the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9-10.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
SeeTire Pressure Monitor System
on page 10-51.

clear the CHANGE ENGINE OIL
SOON message and reset the
oil life at 100%.
Be careful not to reset the oil life
display accidentally at any time

accurately until the next oil
change. See

3-20 Seats and Restraints
Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the driver.
.A frontal airbag for the front
outboard passenger.
.A seat-mounted side impact
airbag for the driver.
.A seat-mounted side impact
airbag for the front outboard
passenger.
.A roof-rail airbag for the driver
and the passenger seated
directly behind the driver.
.A roof-rail airbag for the front
outboard passenger and the
passenger seated directly
behind the front outboard
passenger.
.Seat-mounted side impact
airbags for the second row
outboard passengers.All of the airbags have the word
AIRBAG embossed on the trim or
on a label near the deployment
opening.
For frontal airbags, the word
AIRBAG is on the center of the
steering wheel for the driver and on
the instrument panel for the front
outboard passenger.
For seat-mounted side impact
airbags, the word AIRBAG is on the
side of the seatback closest to
the door.
For roof-rail airbags, the word
AIRBAG is on the ceiling or trim.
Airbags are designed to supplement
the protection provided by safety
belts. Even though today's airbags
are also designed to help reduce
the risk of injury from the force of an
inflating bag, all airbags must inflate
very quickly to do their job.
Here are the most important things
to know about the airbag system:
{Warning
You can be severely injured or
killed in a crash if you are not
wearing your safety belt, even
with airbags. Airbags are
designed to work with safety
belts, not replace them. Also,
airbags are not designed to inflate
in every crash. In some crashes
safety belts are the only restraint.
See
When Should an Airbag
Inflate? on page 3-23.
Wearing your safety belt during a
crash helps reduce the chance of
hitting things inside the vehicle or
being ejected from it. Airbags are
“supplemental restraints” to the
safety belts. Everyone in the
vehicle should wear a safety belt
properly, whether or not there is
an airbag for that person.
