WARNING
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be us ed with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or seri-
ous injury especially if the driver is very close to the airbag. The National Highway
Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a clear
margin of safety. This distance is measured from the center of the steering wheel to
your breastbone. If you sit less than 10 in . (250 mm) away now, you can change your
driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals com-
fortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm) dis-
tance, even with the driver seat all the wa y forward, simply by reclining the back of
the seat somewhat. If reclining the back of your seat makes it hard to see the road,
raise yourself by using a firm , non-slippery cushion, or raise the seat if your vehicle
has that feature.
• If your steering wheel is ad justable, tilt it downward. This points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA ab ove, while still maintain-
ing control of the foot pedals, steering whee l, and your view of the instrument panel
controls.

Operation of each component
GS F_OM_OM30G90U_(U)
When either “L” or “R” of the mirror select switch is selected, \
the outside rear
view mirrors will automatically angle downwards when the vehicle is reversing in
order to give a better view of the ground . To disable this function, select neither
“L” nor “R”.
■Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust the mirror angle at a desired position. The
adjusted angle will be memorized and the mirror will automatically tilt to the
memorized angle whenever the shift leve r is shifted to R from next time.
The memorized downward tilt position of th e mirror is linked to the normal position
(angle adjusted with the shif t lever in other than R). Ther efore, if the normal posi-
tion is changed after adjustment, the tilt position will also change.
When the normal position is chang ed, readjust the angle in reversing.
■Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
■When the mirrors are fogged up
The outside rear view mirrors can be cleare d using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. ( P. 316)
■Automatic adjustment of the mirror angle
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. ( P. 160)
■Auto anti-glare function
When the anti-glare inside re ar view mirror is set to automatic mode, the outside rear
view mirrors will activate in conjunction with the anti-glare inside rear view mirror to
reduce reflected light. ( P. 169)
■Using automatic mode in cold weather (if equipped)
When automatic mode is used in cold weather, the door mirror could freeze up and
automatic stowing and return may not be possible. In this event, remove any ice and snow
from the door mirror, then either operate th e mirror using manual mode or move the mir-
ror by hand.

Driving
◆Pre-collision braking
When the system determines that the possibility of a frontal collision is high,
the system warns the driver. If the syst em determines that the possibility of a
frontal collision is extremely high, the br akes are automatically applied to help
avoid the collision or reduce the collision speed.
◆Suspension control (if equipped)
When the system determines that the po ssibility of a frontal collision is high,
the Adaptive Variable Suspension System ( P. 290) will control the damping
force of the shock absorbers to help ma intain an appropriate vehicle posture.
◆Steering control (if equipped)
When the system determines that the possibility of a frontal collision i\
s high
and the driver is operating the steering wheel, the LDH system ( P. 290) will
control the turning angle of the front an d rear wheels and effort necessary to
turn the steering wheel to help enhance steering responsiveness.
WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-collision sy stem instead of normal braking operations under any
circumstances. This system will not preven t collisions or lessen collision damage or
injury in every situation. Do not overly rely on this system. Failure to do so may lead to
an accident, resulting in death or serious injury.
●Although this system is designed to help avoid a collision or help reduce the impact of
the collision, its effectivenes s may change according to various conditions, therefore
the system may not always be able to achieve the same level of performance.
Read the following conditions carefully. Do not overly rely on this system and always
drive carefully.
• Conditions under which the system may oper ate even if there is no possibility of a
collision: P. 243
• Conditions under which the system may not operate properly: P. 246
●Do not attempt to test the operation of the pre-collision system yourself, as the system
may not operate properly, possib ly leading to an accident.

om, liberally apply water to the vehicle body, wheel
wells and underside of the vehicl e to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wa sh soap and rinse thoroughly with
water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is cool.
■CFRP (Carbon Fiber Reinforced Plastic) part (GS F)
CFRP is used for the part s shown in the illustration.
■Self-restoring coat*
The vehicle body has a self-restoring coating that is resistant to small surface scratches
caused in a car wash etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.
●The restoration time differs depending on the depth of the scratch and outside tem-
perature. The restoration ti me may become shorter when the coating is warmed by
applying warm water.
●Deep scratches caused by keys, coins, etc. cannot be restored.
●Do not use wax that contain abrasives.
*: CFRP parts (GS F) do not have a self-restoring coat.
Perform the following to protect the ve hicle and maintain it in prime condi-
tion:
●As the CFRP parts may change color if they
are exposed to ultraviolet rays for extended
periods of time, Lexus recommends that your
vehicle be stored in a place where it will not be
exposed to direct sunlight.
●Do not use wax that contains abrasives.
●CFRP parts may get scratched when using an
automatic car wash.
