CAUTION
■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 instead of normal braking operations under
any circumstances. This system will not prevent 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. 2 9 3 ,
294). As a result, the same level of performance may not be expected in all cases.
Also, the pre-crash safety brakes may not operate if the driver is depressing the
brake pedal or turning the steering wheel, as the system will determine such condi-
tions 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-cras h 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 position, the system may become inaccurate or
malfunction. If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by any authorized Lexus dealer or repairer, or
another duly qualified and 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.
