WARNING
• When an object is directly under a bumper • When objects become too close to the sensors• When a non-genuine Lexus suspension (l owered suspension, etc.) is installed
In addition to the situations above, there are instances in which, because of their shape, signs and other objects may be judged by th e sensor to be closer than they are.
●The shape of an object may prevent the sensor from detecting it. Pay particular atten-
tion to the following:
• Wires, fences, ropes, etc. • Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects •Low objects• Tall objects with upper sections projecting outwards in the direction of your vehi-
cle • People, animals and other moving objects• People wearing certain types of clothing
●The following situations may occur when using the Lexus parking assist-sensor.
• Depending on the shape of the object and other factors, the detection distance
may be shortened, or detection may not be possible. • Objects may not be detected if they are too close to a sensor.• There will be a short delay between the de tection of an object and display of the
detection. Even at slow speeds, there is a possibility that the object will come within a sensor’s detection area before the display is shown and a warning beep sounds.
• Thin posts or objects lower than a sensor may not be detected when approached, even if they have been detected once.• It might be difficult to hear beeps due to the volume of the audio system or air flow
noise of the air conditioning system.

■When the message is displayed on the multi-information display showing that TRC has
been disabled even if ( ) has not been pressed (RC200t)
TRC and hill-start assist control cannot be operated. Contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
■When the “TRC OFF” indicator light comes on even if ( ) has not been
pressed (RC F)
TRC and hill-start assist control cannot be operated. Contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
■Sounds and vibrations caused by the ABS, brake assist, TRC, VSC and hill-start assist
control systems
●A sound may be heard from the engine compartment when the brake pedal is
depressed repeatedly, when the engine is st arted or just after the vehicle begins to
move. This sound does not indicate that a malfunction has occurred in any of these sys-
tems.
●Any of the following conditions may occu r when the above systems are operating.
None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slig htly after the ABS is activated.
• The brake pedal may move down slig htly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a motor sound may be heard. This does not indi-
cate a malfunction.
■Reactivation of the TRC/VSC systems
Even after the TRC/VSC systems have been turned off, turning the engine off and then
on again will automatically reactivate the TRC/VSC systems.
■Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, th e TRC system will turn on when vehicle speed
increases. However, when both TRC and VSC systems are turned off, the systems will
not turn on even when vehicle speed increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is redu ced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The steering
wheel may feel heavy as a result. Should this occur, refrain from excessive steering input
or stop the vehicle and turn the engine off. The EPS system should return to normal
within 10 minutes.
■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will operate:
●The shift lever is in a position other than P or N (when starting off forward/backward on
an upward incline).
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.

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.
■Handling of tires and the suspension
Using tires with any kind of problem or modif ying the suspension will affect the driving
assist systems, and may cause a system to malfunction.

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.
