Limitations of the pre-collision system
It is the driver’s responsibility to drive safely. The driver should be aware of the sur-
roundings and strive for safe driving.
Do not rely on the pre-collision system inst ead of normal braking operations. This sys-
tem does not avoid or reduce collisions in every situation.
Overly relying on the system and entrusting it with safety may cause an unexpected
accident which could lead to death or serious injury.
Although the system is designed for the pu rpose to support in evading collisions or
reducing the damage of a collision, the effect changes according to various conditions.
( P. 312) Therefore, it does not always provide the same performance. Also, the pre-
collision braking does not work depending on the operating conditions of the driver.
When the driver has stepped on the brake pedal and is operating the steering wheel,
the system judges that the driver is takin g evasive action and the automatic braking
may not operate. ■
Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively.
Otherwise, the system may not function correctly and could result in an accident. ●
Keep the sensor and front grille cover clean at all times.
Clean the sensor and front grille cover with a soft cloth so you do not mark or dam-
age them. ●
Do not subject the sensor or surr ounding area to a strong impact.
If the sensor moves even slightly off position, the system may not normally or malfunc-
tion. If the sensor or surrounding area is subject to a strong impact, always have the
area inspected and adjusted by your Lexus dealer. ●
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 re placed, contact your Lexus dealer.
