5系保养手册5系列车型是宝马品牌的一款豪华车型，享有很高的声誉和口碑。
对于这样一款车型来说，保养是非常重要的，只有做好保养工作，才能确保车辆的性能和使用寿命。
接下来，我将为大家详细介绍5系车型的保养手册，希望能对车主们有所帮助。
首先，我们来看一下常规的保养周期。
按照宝马官方的建议，5系车型的常规保养周期是每1万公里或每12个月。
当然，具体的保养周期还是要根据车辆的具体情况来定，如果车辆行驶在复杂的路况下，比如山区或者沙漠地区，那么可以适当缩短保养周期。
保养项目方面，常规保养包括机油更换、滤芯更换、刹车系统检查等项目。
首先是机油更换，这是保养工作的核心之一。
机油是发动机的“血液”，需要经常更换以确保发动机正常运转。
根据宝马的建议，5系车型的机油更换周期一般为每1万公里或每12个月。
当然，具体的更换周期还是要根据使用环境和使用情况来确定。
机油滤芯的更换周期一般和机油更换周期一样。
滤芯的作用是过滤机油中的杂质和颗粒，防止发动机受到损害。
定期更换滤芯可以确保机油的清洁度，提高发动机的工作效率。
刹车系统是车辆行驶过程中最重要的安全装置之一，必须经常检查和保养。
宝马建议每1万公里或每12个月进行一次刹车系统的检查和维护。
具体的保养内容包括刹车片和刹车盘的检查、刹车油液的更换等。
刹车片和刹车盘是刹车系统的核心部件，需要保持良好的工作状态，以确保刹车的灵敏度和安全性。
另外，还有一些其他的保养项目也需要注意。
比如发动机冷却液的更换，宝马建议每2年或每4万公里进行一次发动机冷却液的更换。
冷却液起到很重要的降温和防锈作用，在使用一段时间后会逐渐失去效果，因此需要定期更换。
还有空调滤芯的更换，宝马建议每2年或每4万公里进行一次空调滤芯的更换。
空调滤芯的作用是过滤空气中的灰尘和颗粒物，防止室内空气污染，对车内乘员的健康非常重要。
此外，需要注意的是，保养工作不仅仅是更换部件，还包括对车辆的常规检查和维护。
比如轮胎的检查和调整，制动系统的检查和清洁等。

On the IHKA high and basic versions, thetemperature and air volume are controlled by means of rotaryselectors.- Extended air conditioning functions such as air stratification orindependent heating (option) are selected and activated by means of the controller in the central information display (CID).- Three different AUTO programs can be set in the CID by means of the controller:soft,standard,intensive.The settings have an effect on the flaps program and on the flaps and blower program.-Modified display concept:-Scope of display elements for the extended A/C functions in the CID similar to those in the E65. The required fan and temperaturesettings are not shown in the CID. The set values for temperature and air volume can be read off from scale rings(air volume in IHKA high: with LED illuminated ring). In the IHKA basic version, airdistribution is set manually at the IHKA control panel/control unit.In the IHKA high version it is set by means of the controller in the CID.-The liquid crystal display from the E39control panel is not installed in the E60.-Only stepper motors are used to actuate the flaps, i.e. no bowden cables.-Separate footwell flaps for left and right (IHKA high only)-Separate ventilation flaps for left and right (IHKA high only)-Suction-action blower arrangement in the air conditioner:The blower is arranged behind the evaporator.The heat exchanger for the heating system is positioned at right angles with respect to the evaporator and is arranged over the blower. This arrangement makes for a very compact air conditioner unit.-The heat exchanger for the heating system (HWT) is identical for the IHKA basic and IHKA high on petrol engine vehicles. A heating heat exchanger with an integrated electric auxiliary heater is fitted on diesel engine vehicles. This heater is also of identical design for the IHKA basic and IHKA high.-Clutchless,externally actuated and output-regulated A/C compressor (E65 common part)-2-gas sensor for automatic recirculating air control (IHKA high only, E65 common part)-Solar sensor located in centre of instrument panel in area of defroster air vent (IHKA high only, E65 common part)- Advantages of the system-Even though the efficiency and functionality of the automatic climate control IHKA have been further improved compared to thepredecessor versions the size of the unit is considerably morecompact than in the E39.-The electric auxiliary heater based on the PTC principle in diesel engine models speeds up the rate the vehicle interior is heatedparticularly at low outside temperatures and during the cold start phase. The windows are also defrosted at a faster rate.-Thanks to the PTC characteristics, the heating elements of the auxiliary heater are intrinsically safe, i.e. they are protected from overheating.-The condensation sensor detects the threat of windscreen misting (condensation) even before it is visible. Misting (condensation) is prevented or automatically eliminated with the aid of the IHKA(IHKA high only).-The progressive evaporator temperature control (2 - 8ºC) ensures a lower level of air dehumidification,thereby reducing the drying effect for mucous membranes while resulting in a measurable fuel saving.IHKA basicThe IHKA basic is fitted as standard in E60 ECE vehicles. The design, function and output of the integrated heating and air conditioning control system (IHKR) installed at the basic version in the E39 are not comparable with those of the IHKA basic in the E60.- New system features-No bowden cables from the control panel to the air conditioner as the flaps in the air conditioner are actuated solely by stepper motors.-New control panel and control unit with extended functionality even in the basic variant: automatic flap control, temperature stratification setting for centre air vents via controllers and CID, OFF button,interior temperature sensor (force-ventilated).-Local interconnect network bus (LIN bus) for controlling the flap stepper motors, the electric auxiliary fan based on the PTC principle and the blower motor in the air conditioner.-Electric auxiliary heater based on the PTC principle (diesel models only).System overview- Positions of the components in the vehicleKT-11245Fig. 1:IHKA basicIndex Explanation Index

compartment on diesel engine vehicles with independent heating.The system overview for the independent heating is described in the chapter IHKA high.Components- IHKA control panel/control unitThe control panel/control unit controls the following functions:-T emperature setting (no right/left separation)-Air distribution: windows, upper body, footwell-Air volume (blower setting)-Air conditioning ON/OFF (refrigerant compressor)-Automatic air distribution-Outside air or recirculating air-Rear window defoggerExtended functions such as air stratification and independent heating (option) are selected and activated by means of the controller in the CID.DesignThe IHKA control panel/control unit consists of5buttons with indicator fields and 3rotary knobs. The force-ventilated temperature sensor for measuring the vehicle interior temperature is also accommodated inthe IHKA control panel/control unit.KT-11117Fig. 8:Design of IHKA control panel/control unitIndex Explanation1Rotary control for air distribution2Opening for force-ventilated vehicle interior temperature sensor3AUTO button*4Rotary knob for blower adjustment (air volume)5A/C button*6OFF button*7Rotary control for temperature setting8Outside air/recirculating air button*9Independent heating indicator */**10Rear window defogger button** with function lighting** light module for independent heating is always fittedFunctional principleThe IHKA control panel/control unit features 3controls with fine settings (24 and 36 positions) for air distribution, blower setting, air supply and temperature setting.The recirculating air button, AUTO button (automatic air distribution) and the A/C button feature a green function light (LED).The button for the rear window defogger and OFF button have an orange function light (LED).A red LED indicates operation of the independent heating option(SA536):-Timer activated: LED steady light-Function active: LED flashesWhen the light is switched on,the locator and function indicator lighting is activated via terminal 58g. The signal comes from the light module (LM).The locator and function lighting is dimmed:-Dependent on the position of the dimmer control on the light module -Dependent on the ambient brightness (photocell on light module)The independent ventilation and residual heat functions are not included in the IHKA basic version.With the recirculating air function selected,after12minutes,the system switches to partial fresh air for 1 minute. The counter for the recircu-lating air time is restarted when the recirculating air function is switched off and then reselected.The refrigerant circuit need not always be activated in recirculating air mode.The IHKA control panel/control unit features 2plug connections at the rear. The holder for the interchangeable sensor blower for ventilatingthe integrated interior temperature sensor is also located at the rear.These plug connections connect the IHKA control panel/control unit to the vehicle electrical system and the heater/air conditioner.KT-11115Fig. 9:Plug connection, IHKA control panel/control unitIndex Explanation118-pin plug connection to vehicle electrical system212-pin plug connection to heater/air conditionerThe following hardware variants are used for the control panel/control unit IHKA basic and IHKA high:Variant Basic High ECE version with independent heating*X XUS version with independent heating**-X ECE version without independent heating X-US version without independent heating**--* with temperature indication in ºCelsius** with temperature indication in ºFahrenheitNote: The table describes the functionality of the control unit irrespective of whether independent heating is installed or not.

The air temperature at the centre air vent can be raised or lowered with respect to this central presetting.KT-11534Fig. 11:Independent heating display in CIDIndex Explanation1Independent heating: switch-on time 12Independent heating: switch-on time 2Special functions of the rear window defogger (HHS)-With the IHKA control panel/control unit switched off(air conditioning functions OFF)the rear window defogger function can be activated by means of the rear window defogger button irrespective of the other settings on the control panel. All other air conditioning functions remain in OFF mode, the function lighting OFF LED remains active. -When the IHKA control panel/control unit is switched on and the rear window defogger function active,the rear window defogger function is also switched off when the control panel is switched off by means of the OFF button.-If both OFF mode and the rear window defogger function are active, pressing any button (except the rear window defogger button),turning the rotary control or adjusting the A/C setting on the CID will switch the control panel on again.The rear window defogger function will remain active.If only the rear window defogger button is pressed, the OFF setting is retained and the rear window defogger function will be deactivated.- Heater/air conditioner IHKA basicThe package space required for the air conditioner in the E60is smaller than that in the E39 and E65. The modified arrangement of the heatexchanger, evaporator and blower compared to the E39 facilitates the more compact size of the air conditioner (see Fig. 14).There are a total of 4 air conditioners: air conditioner IHKA basic andIHKA high each with and without an auxiliary PTC electric heater. The changes in the various types of heater/air conditioner relate to thewiring harness, air distributor housing, the flaps and stepper motors,the coolant connections as well as the heating system heat exchangers.KT-11465Fig. 12:Left view of air conditioner, IHKA basicIndex Explanation1Air conditioner/bulkhead screw mounting point2Y-connector: common heating feed, left/rightKT-11464Fig. 13:Right view of air conditioner, IHKA basicIndex Explanation1Central connection for sensors and stepper motors2System connector, blowerDesignKT-11463Fig. 14:Evaporator, blower and heating system heat exchanger, IHKA basicIndex Explanation1Blower2Evaporator3Heat exchanger for heating systemKT-11367Fig. 15:Stepper motors and temperature sensors, IHKA basicIndex Explanation1T emperature sensor, heat exchanger2Stepper motor, fresh air/recirculating air, right3Stepper motor, ventilation4Stepper motor, cold air5Stepper motor, fresh air/recirculating air, left6T emperature sensor, evaporator7Stepper motor, defrost8Stepper motor, footwellStepper motors6bipolar stepper motors are installed in the IHKA basic.The motors are designed as MUX5motors (multiplex motor type 5).The differences compared to the MUX4motors used in the E65are found in the actuation software. On actuation, the stepper motors are receive their voltage and ground supply from the IHKA control panel/control unit via the LIN bus.Fig. 16:Flap motor with gear mechanism, drive, electronic moduleThe stepper motors for the fresh air/recirculating air flaps are designed as high-speed motors.The number of steps of the stepper motors depends on the adjustment range of the driven flap as follows.KT-11220Blower with blower controllerAn electric blower for generating the necessary air volume is fitted in the heater/air conditioner. The blower features a symmetrical design and is equipped with two dual suction-action radial fan wheels (four-flute blower).KT-11218Fig. 17:BlowerIndex Explanation1Blower controller on blower motorThe blower controller is mounted directly on the housing of the blower motor.The controller features self-diagnosis capabilities and is actuated by the control unit in the IHKA control panel via the LIN bus. It is possible to replace the fan motor without the need to disassemble theinstrument panel.- Microfilter system/intakeThe IHKA basic operates as standard with a microfilter system (MFS) for interior ventilation in the E60.An activated carbon microfilter is fitted in the IHKA high version.Based on the operating time and operating parameters, the "filter condition detection" function determines the load status of the filter without additional sensors.In this way,due service dates for the vehicle are calculated together with other wear-registering components.After changing the filter, the CBS system must be reset via the instrument cluster or in the tester.Recorded parameters for determining the filter load status:-Blower voltage-Road speed-Outside temperature-Rain intensity (IHKA high only, otherwise default)-Sun intensity (IHKA high only, otherwise default)-Day counter-Mileage (kilometer reading)Particular care must be taken when mounting the air conditioner on the inner side of the bulkhead to ensure the seals are fitted correctly. The butyl beading on the seals provides a tight seal with the bulkhead.When assembling, make sure the repair instructions are followedprecisely (contact pressure, duration, component temperature).In the same way as for the seals, particular care must be taken when installing (position of seals) the filtered air duct and the filtercompartment covers. Secondary air may be drawn in from the engine compartment if the seal in the transition of the components in the air duct between the filter and air conditioner is defective.KT-11707Fig. 18:Bulkhead with filtered air duct (without intake/microfilter)Index Explanation1Intake/filter compartment seal2Threaded connection, filtered air duct3Filtered air ductKT-11709Fig. 19:Bulkhead with seal for filtered air ductIndex Explanation1Bulkhead/filtered air duct seal2Aperture for expansion valve3Aperture for water connections, heating circuit4Aperture for air conditioner and screw mounting points and sealsKT-11708Fig. 20:Microfilter systemIndex Explanation1Microfilter compartment2Water drain3Bulkhead/filtered air duct seal4Filtered air ductSystem functionsSystem functions in control panel/control unit IHKA basic System functions in control panel/control unit IHKA highHeat exchanger control Heat exchanger control with left/rightseparationInterior temperature control Interior temperature with left/right separation Evaporator temperature control Evaporator temperature controlVentilation temperature control (stratification)Ventilation temperature control (stratification)No automatic blower function Automatic blower control with solar sensorinfluenceAutomatic air distribution without left/right separation Automatic air distribution for defrost Automatic air distribution with left/right separation for footwell and ventilation Individual air distribution defrost 0-100% Individual air distribution footwell and venti-lation 0-100% with left/right separationRecirculating air mode Recirculating air modeAutomatic recirculating air mode with two-gas sensor controlWater valve actuation Dual water valve actuationDefrostMAX ACResidual heatFogging (condensation) avoidance in AUTOprogram (condensation sensor)Solar sensor: air volume/temperatureadaptation with left/right separationT emperature control, rear compartmentstratificationKey memoryCar memorySensor inputsRear window defogger actuationHeated washer water jet actuationActuation of A/C compressor, A/C compressor inlet, A/C compressor protection functions Calculation of load moment of externally controlled A/C compressorActuation of electric fan on cooling module via K-CANControl of progressive evaporator temperatureActuation of stepper motors via LIN busActuation of blower via LIN busActuation of electric auxiliary PTC-type heater via LIN busElectric load cutout, electric auxiliary heater by DDE/DME (looped through)Interaction of IHKA control panel/control unit with man-machine interface(MMI integrated in M-ASK or CCC)Actuation of auxiliary water pumpLED dimmerActuation of independent heatingCalculation of air filter status (CBS)Flash programmingSelf-diagnosis, IHKA control panel/control unitDiagnosis of stepper motors on LIN busDiagnosis of blower output stage on LIN busDiagnosis of electric auxiliary PTC-type heater on LIN busSystem functions in control panel/controlunit IHKA basic System functions in control panel/control unit IHKA high- Vehicle interior temperature controlThe IHKA control panel/control unit is the central control module for temperature control in the vehicle interior.The required temperature (setpoint) is set on the IHKA control panel/ control unit by means of a rotary temperature selector.The temperature is controlled with the aid of the ventilated interior temperature sensor in the IHKA control panel/control unit.The mass air flow for temperature control of the vehicle interior is produced by a radial blower in the air conditioner. T ogether with the road speed(K-CAN signal)backpressure compensation is realized with the fresh air flap/recirculating air flap for the purpose of maintaining the mass air flow in the air inlet ducts as constant as possible at different driving speeds.In a reheat process, the mass air flow in the air conditioner is initially cooled and dried at the evaporator (provided the A/C compressor is switched on) and then heated to the set temperature at the heating system heat exchanger (HWT).The temperature at the heat exchanger is controlled by means of a temperature sensor on the heating system heat exchanger and a clocked water valve that is actuated by a PWM signal.A heat exchanger characteristic map defines the opening times of the water valve depending on the engine variant and engine speed.A water pump and an auxiliary electric water pump provide the necessary water throughput in the heating circuit.The evaporator temperature is controlled by means of a temperature sensor on the evaporator and a controllable expansion valve. An output-controlled refrigerant compressor generates the pressure in the refrigerant circuit and therefore the necessary low-temperature energy in the evaporator.A progressive evaporator temperature between2and 8ºC facilitates an effective reheat process used to optimize the energy output.Inclusion of the outside temperature via the K-CAN guarantees a subjectively perceived uniform interior temperature at different outside temperatures.The temperature for the driver and passenger can be set separately in the IHKA high variant. This requires a heat exchanger with left/right separation. T ogether with the IHKA control panel/control unit, a dual water valve in the heating feed circuit and two temperature sensors on the heat exchanger form the heating control circuit.In the IHKA high variant, solar sensors for the driver's and passenger's side compensate for additional temperature influences of the sun.- Air distribution-Individual air distribution setting(360ºrotary control with36positions) -Automatic air distribution (AUTO button)The air volume of the blower remains unchanged when the automatic air distribution setting is changed by means of the "air distribution" rotary control. The function light in the AUTO button goes out.An important prerequisite for optimum air distribution is that the manually adjustable air vents are open.。

2021 款宝马525i功能使用说朋书（一）中控按键
1、车身电子稳定系统（ESP）
系统默认开启，除非雨雪等湿滑路面，一般情况不建议关闭。
2、驻车雷达/影像
中控屏显示倒车影像，雷达监测靠近障碍物会有报警音。
3、内/外循环
内循环指车内的空气加热或制冷再送回车内，外循环则是让外界的空气进入车内。
一般在拥堵或者外界空气环境不好的情况下打开内循环。
高速路段应该每隔一个小时左右切换外循环，更替车内外的空气，以防缺氧。
4、温区同步
开启温区同步功能后，改变主驾驶位的温度，其余几个温区也会进行同步的变化。
另外，此功能关闭后，每个分区就可能单独调整温度，更加人性化。
5、自动启停
主要作用：使发动机短暂熄火。
当放开刹车踏板时，发动机重新工作推动车辆前进。
6、自动驻车
在红绿灯等停车的情况，松开刹车踏板后，自动驻车功能会锁住车轮，解放车主的脚部疲劳。
当车主再次踩下油门踏板时，电子驻车就会解锁车轮。
