1-2. Opening, closing and locking the doors and trunk
1
Before driving
Locking and unlocking the doors (front door handles only)
Press the lock button to lock the
door.
Grip the handle to unlock the
door.
Make sure to touch the sensor on
the back of the handle.
The door cannot be unlocked for 3
seconds after the door is locked.
Unlocking the trunk
Press the button to unlock the
trunk.

1-3. Adjustable components
Pre-collision seat belts (front seats of vehicles with pre-collision system)
When the pre-collision sensor detects an obstacle and determines that a
collision is unavoidable, the seat belts lessen collision injury by retracting
the slack in the front seat belts before the collision, thus restraining the
driver and passenger at an earlier stage.
The seat belts will also operate in the event of sudden braking. (P. 1 5 4 )
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if
you lean forward too quickly. A slow, easy motion will allow the belt to extend so that
you can move around fully.
■Automatic locking retractor (ALR)
When a passenger's shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is
used to hold the CRS firmly. To free the belt again, fully retract the belt and then pull
the belt out once more. (P. 8 0 )
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. (P. 3 4 )
Women who are pregnant should position
the lap belt as low as possible over the hips in
the same manner as other occupants. Extend
the shoulder belt completely over the shoul-
der and position the belt across the chest.
Avoid belt contact over the rounding of the
abdominal area.
If the seat belt is not worn properly, not only a
pregnant woman, but also the fetus could suf-
fer death or serious injury as a result of sud-
den braking or a collision.

1-3. Adjustable components
Anti-glare inside rear view mirror
■To prevent sensor error
CAUTION
■Caution while driving
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and an accident, resulting in death
or serious injury.
In AUTO mode, sensors are used to detect the headlights of vehicles
behind and automatically reduce the reflected light.
Turns AUTO mode ON/OFF
The indicator comes on when
AUTO mode is turned ON.
The anti-glare mirror default
mode is AUTO. The anti-glare
mirror is automatically set to
AUTO whenever the engine
switch is turned on.
To ensure that the sensors operate properly,
do not touch or cover them.

1-7. Safety information
Airbag system components
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the driver seat’s position sensor etc. The
front passenger’s airbag system consists of the front passenger occupant
classification sensor etc.
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.Knee airbags

1
Before driving
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
■SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag sensors,
side and curtain shield airbag sensor assemblies, curtain shield airbag sensor
assemblies, driver's seat position sensor, driver's seat belt buckle switch, seat belt
pretensioner assemblies, inflators, interconnecting wiring and power sources.
(P. 3 4 0 )
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the front seats, and parts of the front pillar, rear pillar and roof side rail,
may be hot for several minutes. The airbag itself may also be hot.
●The front windshield may crack.
■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision when the vehicle impacts straight into a fixed barrier that does not move
or deform.
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle "underrides", or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
●The SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the front passenger airbag may deploy if
luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccu-
pied. (P. 7 2 )

When driving
AFS (vehicles with discharge headlights)
AFS (Adaptive Front Lighting System) improves visibility at intersections
and on curves by automatically adjusting the level of the headlights
according to vehicle speed and the degree of the tire angle that are con-
trolled by steering input.
Operates at speeds of 6 mph (10 km/h) or higher.
■Deactivating AFS
How to switch: P. 2 2 2
The indicator turns on when the AFS is deactivated.
■Daytime running light system
To make your vehicle more visible to other drivers, the headlights turn on automati-
cally (at a reduced intensity) whenever the engine is started and the parking brake
is released. Daytime running lights are not designed for use at night.
■Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

124
2-3. Operating the lights and windshield wipers
■Automatic light off system
●When the headlights comes on: The headlights and tail lights turn off 30 sec-
onds after a door is opened and closed if the engine switch has been switched
to ACC or turned OFF. (The light turns off immediately if the button on
the key is pressed after all doors are locked.)
●When only the tail lights come on: The tail lights turn off automatically if the
engine switch is switched to ACC or turned OFF and driver’s door is opened.
To turn the lights on again, switch to IG-ON mode, or turn the light switch OFF
once and then back to the or position.
■Automatic headlight leveling system (vehicles with discharge headlights)
The level of the headlights is automatically adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights do
not interfere with other road users.
■If the indicator flashes... (vehicles with discharge headlights)
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Customization
Settings (e.g. light sensor sensitivity) can be changed. (P. 406)
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not running.
