WARNING
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as excessively
worn tires on a snow covered road).
●The vehicle hydroplanes while driving at high speed on wet or slick roads.
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road surfaces, even if the TRC system is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
■Hill- start assist control does not operate effectively when
●Do not overly rely on hill-start assist control. Hill-start assist control may not operate
effectively on steep inclines and roads covered with ice.

The slip indicator light flashes. Always drive carefully. Reckless driving may cause an accident. Exercise particular care when the indicator light flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As these are the systems to help ensure vehicle stability and driving force, do not turn the TRC/
VSC systems off unless necessary.
■Expert mode precautions
●Do not use on public roads.
●Use only when the road conditions and safety of the surrounding area can be ensured.
●Proper use of expert mode re quires a professional level of driving skill. When using
expert mode, always check the road condit ions and surrounding area and drive more carefully than usual.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load capacity. In addition, make sure that the tire s are inflated to the recommended tire infla- tion pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires are installed on the vehicle.Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional for further information when replacing tires or wheels.

WARNING
■Limitations of the pre-crash safety system
●The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
Do not use the pre-crash safety system in stead of normal braking operations under any circumstances. This system will not pr event collisions or lessen damage or inju- ries in all cases. Do not overly rely on this system. Failure to do so may cause an acci-
dent, resulting in death or serious injury.
●This system has been designed to help avoid and reduce the impact of collisions. However, the system operates differently depending on the situation ( P. 358,
358). As a result, the same level of perf ormance may not be expected in all cases. Also, the pre-crash safety brakes may not oper ate if the driver is depressing the brake pedal or turning the steering wheel, as th e system will determine such conditions as
collision avoidance operations.
●As the pre-crash safety system is designed to assist the driver in safe driving, it may operate under sporty driving conditions, which may cause an accident. For this rea-
son under sporty driving conditions, it is recommended that this system be disabled by using the PCS OFF switch.
■Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function effectively. Otherwise, the system may not function correctly and could result in an accident.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off po sition, the system may become inaccurate or malfunction. If the sensor or surrounding area is subject to a strong impact, alwayshave the area inspected and adjusted by an y authorized Lexus dealer or repairer, or
another duly qualified an d equipped professional.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding area.
●Do not modify or paint the sensor and grille cover.
●If the radar sensor needs to be replaced, contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a vehicle is in a blind spot of the outside rear view mirrors or is approaching rapidly from behind intoa blind spot. Do not overly rely on the BSM function. As the function cannot judge if it is
safe to change lanes, over reliance could lead to an accident resulting in death or seri- ous injury.
As the system may not function correctly under certain conditions, the driver’s own
visual confirmation of safety is necessary.
