OCCUPANT RESTRAINT SYSTEMS
139
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 front 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 front side airbag inflates with
considerable speed and force. Otherwise, you may
be killed or severely injured.
 Do not use seat accessories which cover the parts
where the front side airbags inflate. Such
accessories may prevent the front side airbags from
activating correctly, causing death or serious injury.
 Do not modify or replace the front seats or upholstery
of the seats equipped with front side airbags. Such
change may prevent the side airbag system from
activating correctly, disable the system or cause the
front side airbags to inflate accidentally, resulting in
death or serious injury.
