SWITCHES

Automatic headlight leveling system
The headlight beam level is always maintained automatically
at the proper level in all loading conditions so that your
headlights do not dazzle other road users.
If the system fails, the “AFS OFF” indicator light in the
instrument cluster will flash. If this occurs, have your vehicle
checked by your Lexus dealer.
Adaptive Front Lighting System (AFS)
Adaptive Front Lighting System (AFS) provides the proper
headlight beam level according to the current driving
conditions. This system moves the headlight beam left or right
according to the turning angle of the steering wheel. The
synergy of this system and the automatic headlight leveling
system improves visibility at the intersections and curves.
The system operates when the vehicle speed increases above
10 km/h (6 mph), and stops when the vehicle speed drops
below 10 km/h (6 mph).
The system can operate within the limited range of the steering
wheel turning angle.

OCCUPANT RESTRAINT SYSTEMS
154
SEATS
While the vehicle is being driven, all vehicle occupants should
have the seatback upright, sit well back in the seat and properly
wear the seat belts provided.
CAUTION
 Do not drive the vehicle unless the occupants are
properly seated. Do not allow any passengers to sit
in the luggage compartment or cargo area. Persons
not properly seated and/or not properly restrained by
seat belts can be severely injured in the event of
emergency braking or a collision.
 During driving, do not allow any passengers to stand
up or move around between seats. Otherwise, severe
injuries can occur in the event of emergency braking
or a collision.
FRONT SEATS
Front seat precautions
Driver seat
CAUTION
The SRS driver airbag deploys with considerable force,
and can cause death or serious injury especially if the
driver is very close to the airbag. The National Highway
Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver airbag is the first 5075
mm (23 in.) of inflation, placing yourself 250 mm (10 in.)
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 250 mm (10 in.) 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 comfortably.
 Slightly recline the back of the seat. Although vehicle
designs vary, many drivers can achieve the 250 mm
(10 in.) distance, even with the driver seat all the way
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,
nonslippery cushion, or raise the seat if your vehicle
has that feature.

OCCUPANT RESTRAINT SYSTEMS
155
If your steering wheel is adjustable, 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 above, while still maintaining control of the foot
pedals, steering wheel, and your view of the instrument
panel controls.
Front passenger seat
CAUTION
The SRS front passenger airbag also deploys with
considerable force, and can cause death or serious
injury especially if the front passenger is very close to
the airbag. The front passenger seat should be as far
from the airbag as possible with the seatback adjusted,
so the front passenger sits upright.
Front seats
CAUTION
The SRS side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
 Do not lean against the front door when the vehicle
is in use, since the side airbag inflates with
considerable speed and force. Otherwise, you may
be killed or severely injured.
 Do not use seat accessories which cover the area
where the side airbags inflate. Such accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
 Do not modify or replace the seats or the upholstery
of the seats equipped with side airbags. Such
change may prevent the side airbag system from
activating correctly, disable the system, or cause the
side a irbags to inflate accidentally, resulting in death
or serious injury.

OCCUPANT RESTRAINT SYSTEMS
184Deployment of the
airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, primarily to the
head and chest, it may also cause other, less severe injuries
to the face, chest, arms and hands. These are usually in the
nature of minor burns or abrasions and swelling, but the force
of a deploying airbag can cause more serious injuries,
especially if an occupant’s hands, arms, chest or head is in
close proximity to the airbag module at the time of deployment.
This is why it is important for the occupant to; avoid placing any
object or part of the body between the occupant and the airbag
module; sit straight and well back into the seat; wear the
available seat belt properly; and sit as far as possible from the
airbag module, while still maintaining control of the vehicle.
Parts of the airbag module (steering wheel hub, lower portion
of instrument panel, airbag cover and inflator) may be hot for
several minutes after deployment, so do not touch! The
airbags inflate only once. The windshield may be damaged by
absorbing some of the force of the inflating airbag.
CAUTION
The driver or front passenger who is too close to the
steering wheel, lower portion of instrument panel or
dashboard during airbag deployment can be killed or
seriously injured. Lexus strongly recommends that:
 The driver sit as far back as possible from the
steering wheel while still maintaining control of the
vehicle.
 The front passenger sit as far back as possible from
the dashboard.
 All vehicle occupants be properly restrained using
the available seat belts.
 If the seat belt extender has been connected to the
driver’s seat belt buckle but the seat belt extender
has not also been fastened to the latch plate of the
driver’s seat belt, the SRS driver’s airbag system will
judge that the driver is wearing the seat belt even
though the seat belt has not been connected. In this
case, the driver’s airbag may not activate correctly,
causing death or serious injury in the event of a colli-
sion. Be sure to wear the seat belt with the seat belt
extender. Otherwise, there will also not be any effec-
tive protection in a sudden stop or a collision pro-
vided by the seat belt.
For instructions and precautions concerning the
seating position, see “Front seat precautions” on page
154.

OCCUPANT RESTRAINT SYSTEMS

16L794
Do not put anything or any part of your body on or in
front of the dashboard, lower portion of instrument
panel, steering wheel pad that houses the front
airbag system or in the areas where the SRS knee
airbags will inflate. They might restrict inflation or
cause death or serious injury as they are projected
rearward by the force of the deploying airbags.
Likewise, the driver and front passenger should not
hold objects in their arms or on their knees.
 If a vinyl cover is put on the area where the SRS knee
airbag will deploy, be sure to remove it.
Do not attach any objects except Lexus genuine
parts in the area where the SRS knee airbag for the
front passenger will inflate. When using an ashtray
or auxiliary box on the front passenger’s console
box, be sure to keep it closed. The attached object, or
opened ashtray or auxiliary box might restrict
inflation of the airbag or be thrown away by the force
of the deploying airbag, causing a danger.
 Do not modify or remove any wiring. Do not modify,
remove, strike or open any components, such as the
steering wheel pad, steering wheel, column cover,
dashboard near the front passenger airbag, front
passenger airbag cover, front passenger airbag,
knee airbags or airbag sensor assembly. Doing so
may prevent the front airbag system from activating
correctly, cause sudden activation of the system or
disable the system, which could result in death or
serious injury.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer about any
repair and modification.
