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

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.

Seat adjustment precautions
CAUTION
Do not adjust the seat while the vehicle is moving as
the seat may unexpectedly move and cause the
driver to lose control of the vehicle.
 Be careful that the seat does not hit a passenger,
luggage or the rear seat.
NOTICE
Do not operate the control switch in more than one
dimension at a time. It may cause electrical overload.

For passenger’s seat
Move the control switch in the desired direction.
Releasing the switch will stop the seat in that position. Do not
place anything under the seat as this might interfere with the
seat movement.
Adjusting seatback angle

Move the control switch in the desired direction.
Releasing the switch will stop the seatback in that position.
CAUTION
Avoid reclining the seatback any more than needed.
The seat belts provide maximum protection in a frontal
or rear collision when the driver and the front passenger
are sitting up straight and well back in the seats. If you
are reclined, the lap belt may slide past your hips and
apply restraint forces directly to the abdomen or your
neck may contact the shoulder belt. In the event of a
frontal collision, the more the seat is reclined, the
greater the risk of death or personal injury.

CAUTION
If you operate the switch when a front passenger is
seated or he/she is getting on or off the front passenger
seat, take full safety precautions beforehand by telling
the occupant that the seat is about to move.

CAUTION
If you operate the switch when an occupant is seated
or when he/she is getting on or off the front
passenger seat, take full safety precautions
beforehand by telling the occupant that the seat is
about to move.
 Avoid reclining the seatback any more than needed.
The seat belts provide maximum protection in a
frontal or rear collision when the front passenger is
sitting up straight and well back in the seats. If he/she
is reclined, the lap belt may slide past his/her hips
and apply restraint forces directly to the abdomen or

SEAT BELTS
Seat belt precautions
Lexus strongly urges that the driver and passengers in the
vehicle be properly restrained at all times with the seat belts
provided. Failure to do so could increase the chance of injury
and/or the severity of injury in accidents.
The seat belts provided for your vehicle are designed for
people of adult size, large enough to properly wear them.
Child. Use a child restraint system appropriate for the child
until the child becomes large enough to properly wear the
vehicle’s seat belts. See “Child restraint” on page 199 for
details.
If a child is too large for a child restraint system, the child should
sit in the rear seat and must be restrained using the vehicle’s
seat belt. According to accident statistics, the child is safer
when properly restrained in the rear seat than in the front seat.
If a child must sit in the front seat, the seat belts should be worn
properly. If an accident occurs and the seat belts are not worn
properly, the force of the rapid inflation of the airbag may cause
death or serious injury to the child.
Do not allow any children to stand up or kneel on either rear or
front seats. An unrestrained child could suffer serious injury or
death during emergency braking or a collision. Also, do not let
the child sit on your lap. Holding a child in your arms does not
provide sufficient restraint. Pregnant
woman. Lexus recommends the use of a seat belt.
Ask your doctor for specific recommendations. The lap belt
should be worn securely and as low as possible over the hips
and not on the waist.
Injured person. Lexus recommends the use of a seat belt.
Depending on the injury, first check with your doctor for specific
recommendations.
CAUTION
Persons should ride in their seats properly wearing
their seat belts whenever the vehicle is moving.
Otherwise, they are much more likely to suffer serious
bodily injury or death in the event of sudden braking or
a collision.
When using the seat belts, observe the following:
 Use the belt for only one person at a time. Do not use
a single belt for two or more people even children.
 Avoid reclining the seatback any more than needed.
The seat belts provide maximum protection in a
frontal or rear collision when the driver and the front
passenger are sitting up straight and well back in the
seats. If you are reclined, the lap belt may slide past
your hips and apply restraint forces directly to the
abdomen or your neck may contact the shoulder belt.
In the event of a frontal collision, the more the seat is
reclined, the greater the risk of death or personal
injury.
