Both highpositioned lap belts and loosefitting
belts could cause death or serious injuries due to
sliding under the lap belt during a collision or other
unintended event. Keep the lap belt positioned as
low on a child’s hips as possible.
 For child’s safety, do not place the shoulder belt
under child’s arm.
 After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt are not twisted.
 Do not insert coins, clips, etc. in the buckle as this
may prevent your child from properly latching the tab
and buckle.
 If the seat belt does not function normally, it cannot
protect your child from death or serious injury.
Contact your Lexus dealer immediately. Do not
install the child restraint system on the seat until the
seat belt is fixed.

PRECOLLISION SAFETY SYSTEM
(Vehicles with dynamic radar cruise control)
When the precollision safety system detects what it
perceives to be an unavoidable collision, the front seat
belts are quickly drawn back by the retractors
(precollision seat belts) and more powerful braking is
applied according to the amount of pedal depression to
help reduce injury to the occupants and damage to the
vehicle body. In addition, the electronically modulated air
suspension works to help regulate the vehicle not to pitch
forward so much.
Precollision sensor
The millimeter wave radar sensor detects vehicles or
objects near or on the road your vehicle is traveling and
determines the possibility of a collision based on the
object position, vehicle speeds and the course you are
traveling.
The pre −collision sensor will operate in the following
conditions:
 When the ignition switch is turned on.
 When the vehicle speed is about 5 km/h (3 mph) or over.
(The pre−collision safety system does not work with the
vehicle stopped.)
31L359a

Millimeter wave grille cover
2Millimeter wave radar sensor
The millimeter wave radar sensor is installed in the front grille
of the hood.
The millimeter wave radar sensor cannot detect plastic objects
such as pylons, and may not detect people, animals, bicycles,
motor cycles, trees, snowbanks, etc. as objects with which
your vehicle may collide.

STARTING AND DRIVING
375
CAUTION
To ensure that precollision safety system will function
properly while driving, observe the following. Failure to
follow these instructions could reduce the
effectiveness of the precollision safety system in case
of vehicle accident:
 Always keep the millimeter wave radar sensor and
grille cover clean. When cleaning, use a soft cloth
and be careful not to damage the sensor and grille
cover.
 Avoid strong impacts around the millimeter wave
radar sensor. An incorrect millimeter wave radar
sensor alignment will result in system malfunction.
A special device is required to adjust the millimeter
wave radar sensor alignment. Be sure to have the
sensor adjusted by your Lexus dealer.
 Do not disassemble the millimeter wave radar
sensor.
 Do not affix a sticker (including a transparent sticker)
or attach an accessory around the millimeter radar
sensor or the grille cover.
 Do not modify or paint the grille cover. When
replacing the cover, be sure to use a genuine cover.
Precollision seat belts (Front seat belts only)
When the precollision sensor detects an object or
vehicle with which your vehicle might collide and
determines that a collision may be unavoidable, the seat
belts are quickly drawn back by the retractors to enhance
the effects of the seat belt pretensioners. The
precollision seat belts also work as well when hard
braking.
The pre −collision seat belts will operate in the following
conditions:
 When the ignition switch is turned on.
 When the vehicle speed is about 5 km/h (3 mph) or over.
 When the approaching speed in regard to the object or the
vehicle exceeds about 30 km/h (18 mph).
 When the front seat occupants wear the seat belts.
