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 6 0 )
■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 child restraint system (CRS) firmly. To free the belt again, fully
retract the belt and then pull the belt out once more. ( →P. 9 6 )
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. (→P. 5 0 )
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.

CAUTION
■Wearing a seat belt
Observe the following precautions to reduce the risk of injury in the event of sud-
den braking or an accident.
Failing to do so may cause death or severe injury.
●Ensure that all passengers wear a seat belt.
●Always wear a seat belt properly.
●Each seat belt should be used by one person only. Do not use a seat belt for more
than one person at once, including children.
●Lexus recommends that children be seated in the rear seat and always use a seat
belt and/or an appropriate child restraint system.
●Do not recline the seat any more than necessary to achieve a proper seating
position. The seat belt is most effective when the occupants are sitting up straight
and well back in the seats.
●Do not wear the shoulder belt under your arm.
●Always wear your seat belt low and snug across your hips.
■Seat belt pretensioners
Do not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger's weight, which prevents the sensor from detecting the
passenger's weight properly. As a result, the seat belt pretensioner for the front pas-
senger's seat may not activate in the event of a collision.
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed
in the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts.
Do not use a damaged seat belt until it is replaced. Damaged seat belts cannot
protect an occupant from death or serious injury.
●Ensure that the belt and tab are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Lexus
dealer.
●Replace the seat assembly, including the belts, if your vehicle has been involved in
a serious accident, even if there's no obvious damage.

■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 reduces 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
START STOP” switch is turned
on.
To ensure that the sensors operate properly,
do not touch or cover it.

Airbag system componentsYour 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. Front passenger airbag

Before driving
ES350_U_(L/O_0708)The main SRS airbag system components are shown above. The SRS
airbag system is controlled by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sensor and an airbag sensor.
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.
■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 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. (

When driving
ES350_U_(L/O_0708)
AFS (vehicles with discharge headlights)AFS (Adaptive Front Lighting System) improves visibility at intersections
and on curves by automatically adjusting the direction of light axis of the
headlights according to vehicle speed and the degree of the tire angle
that are controlled by steering input.
Operates at speeds of 6 mph (10 km/h) or higher.
■ Deactivating AFS
Turn the switch OFF to deactivate
AFS.
OFF
ON
■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 control system to mal-
function.

2-3. Operating the lights and windshield wipers
ES350_U_(L/O_0708)
■Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 seconds
after all doors are closed with the “ENGINE START STOP” switch switched to
ACCESSORY mode 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 START STOP” switch to ACCESSORY mode or turned OFF and
driver’s door is opened.
To turn the lights on again, switch to IGNITION 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... (veh icles with discharge headlights)
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Customization that can be configured at Lexus dealer
Settings (e.g. light sensor sensitivity) can be changed. (Customizable features →P.
433)
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not running.
