Six-year/70,000-mile Powertrain Warranty. Six-year/unlimited-mileage Corrosion Perforation Warranty. All warranties with zero deductible. See the LX Warranty and Services Guide at your Lexus dealer for details. DISCLOSURES 1. Mark Levinson ® is a registered trademark of Harman International Industries, Inc. 2. The LX 570 is designed to meet most off-road driving requirements. Abusive use may result in bodily harm or damage. Lexus encourages responsible operation to help protect you, your vehicle and the environment. Seatbelts should be worn at all times. Please do not allow passengers to ride in the cargo area. Tow hitch receivers/ball mount kits are not intended to provide crash protection. 3. The backup camera does not provide a comprehensive view of the rear area of the vehicle. Y ou should also look around outside your vehicle and use your mirrors to confirm rearward clearance. Cold weather may limit effectiveness and view may become cloudy. 4. The Wide-view Front and Side Monitor does not provide a comprehensive view of the front and side areas of the vehicle. Y ou should also look around outside your vehicle and use your mirrors to confirm clearance. Cold weather will limit effectiveness and view may become cloudy. 5. The Wide-view Side Monitor system does not provide a comprehensive view of the front passenger-side area of the vehicle. Y ou should also look around outside your vehicle and use your mirrors to confirm clearance. Cold weather will limit effectiveness and view may become cloudy. 6. Cargo and load capacity limited by weight and distribution. 7. Always drive safely, obey traffic laws & focus on the road while driving. Apps/services vary by phone/carrier; functionality depends on many factors. Select apps use large amounts of data, you are responsible for all charges. Apps/services are subject to change. Apps identified by ™ or ® are trademarks or registered trademarks of their respective companies. For enrollment, cost and more details, see /enform. 8. Contact with the response center may not be available in all areas. Service Agreements required. A variety of subscription terms available; charges will vary. See for details. 9. A single-disc DVD player is standard. A separate DVD player or game system utilizing the center console’s video/audio inputs is required in order to use the split-screen function of the dual-screen system. 10. Headphones are for passenger use only. Do not use while operating vehicle. 11. Crawl Control is designed for driving on difficult terrain at low speeds. It assists the driver by controlling acceleration and braking, allowing the driver to focus on steering. The LX 570 is designed to meet off-road driving requirements, but off-roading is inherently dangerous. Always wear seatbelts. 12. Ratings achieved using the required premium unleaded gasoline with an octane rating of 91 or higher. If premium fuel is not used, performance will decrease. 13. Before towing, confirm your vehicle and trailer are compatible, hooked up properly and you have any necessary additional equipment. If gross trailer weight is above 5,000 lb (2,268 kg ), it is necessary to use a weight-distributing hitch with sufficient capacity. Do not exceed any Weight Ratings and follow all instructions and cautions from your trailer-hitch manufacturer and vehicle Owner’s Manual . The maximum amount you can tow depends on the total weight of any cargo, occupants and available equipment. 14. Please consult your Lexus dealer or Owner’s Manual for towing and load specifications. 15. The Pre-Collision System is designed to help reduce the crash speed and damage in certain frontal collisions only. It is not a collision-avoidance system and is not a substitute for safe and attentive driving. System effectiveness depends on many factors, such as speed, driver input and road conditions. See Owner’s Manual for further information. 16. The Wide-view Front Monitor does not provide a comprehensive view of the front area of the vehicle. Y ou should also look around outside your vehicle and use your mirrors to confirm clearance. Cold weather will limit effectiveness and view may become cloudy. 17. Availability and accuracy of the information provided by the Navigation System or any SiriusXM™ and/or HD Radio™ services mentioned (if installed ) are dependent upon many factors. Use common sense when relying on information provided. Services not available in every city or roadway. Periodic Enform app updates do not include Navigation updates. Navigation updates are available at an additional cost from your local dealer. See Navigation Owner’s Manual or contact SiriusXM for details. 18. Trailer Sway Control (TSC ) is an electronic system designed to help the driver maintain vehicle control under adverse conditions. It is not a substitute for safe driving practices. Factors including speed, road conditions and driver steering input can all affect whether TSC will be effective in preventing a loss of control. See Owner’s Manual for details. 19. TORSEN ® is a registered trademark of Zexel Torsen, Inc. 20. All the airbag (AB ) systems are Supplemental Restraint Systems. All ABs are designed to inflate only under certain conditions and in certain types of severe collisions: frontal and knee ABs typically inflate in frontal collisions; side and side curtain ABs in side collisions; Roll-Sensing Curtain ABs at a severe tilt degree, roll or lateral G-force. In all other accidents, the ABs will not inflate. To decrease the risk of injury from an inflating AB, always wear seatbelts, sit upright in the middle of the seat as far back as possible and do not lean against the door. Do not put objects in front of an AB or around the seatback. Do not use a rearward-facing child seat in any front passenger seat. The force of an inflating AB may cause serious injury or death. See Owner’s Manual for further information/warnings. 21. The Adaptive Front Lighting System helps improve vision at night. Situations such as dirty windshield, rapidly changing light conditions or hilly terrain will limit effectiveness, requiring the driver to manually turn off. See Owner’s Manual for details. 22. Smart Stop Technology operates only in the event of certain simultaneous brake and accelerator pedal applications. When engaged, the system will reduce power to help the brakes bring the vehicle to a stop. Factors including speed, road conditions and driver input can all impact stopping distance. Smart Stop T echnology is not a substitute for safe and attentive driving and does not guarantee instant stopping. See Owner’s Manual for further details. 23. Continuous average power, all channels driven, at less than 0.1% THD; 20–20,000 Hz. 24. Dynamic Radar Cruise Control is designed to assist the driver and is not a substitute for safe and attentive driving practices. See Owner’s Manual for details. 25. The SmartAccess system may interfere with some pacemakers or cardiac defibrillators. If you have one of these medical devices, please talk to your doctor to see if you should deactivate this system. 26. The engine immobilizer is a state-of-the-art anti-theft system. When you insert your key into the ignition switch or bring a SmartAccess fob into the vehicle, the key transmits an electronic code to the vehicle. The engine will only start if the code in the transponder chip inside the key/fob matches the code in the vehicle’s immobilizer. Because the transponder chip is embedded in the key/fob, it can be costly to replace. If you lose a key or fob, your Lexus dealer can help. Alternatively, you can find a qualified independent locksmith to perform high-security key services by consulting your local Y ellow Pages or by contacting . 27. 20-in performance tires are expected to experience greater tire wear than conventional tires. Tire life may be substantially less than 20,000 miles, depending upon driving conditions. 28. Performance figures are for comparison only and were obtained with prototype vehicles by professional drivers using special safety equipment and procedures. Do not attempt. 29. 2014 EPA-estimated ratings. Actual mileage will vary.Lexus strives to build vehicles to match customer interest, and thus they typically are built with popular options and option packages. Not all options/packages are available separately, and some may not be available in all regions of the country. See for information about options/packages commonly available in your area. If you would prefer a vehicle without any or with different options, contact your dealer to check for current availability or the possibility of placing a special order. Specifications, features, equipment, technical data, performance figures, options, and color and trim are based upon information available at time of printing, are subject to change without notice, and are for mainland U.S.A. vehicles only.
