seatback symbol.
This symbol will appear on the
climate control display to indicate

medium, and low and to turn the
heated seat off. Indicator bars next to
the symbol designate the level of
heat selected: three for high, two for

1-6 Seats and Restraint System

Rollover capable roof-rail airbags
are designed to help contain
the head and chest of occupants in
the outboard seating positions in
the rst, second, and third rows. The
rollover capable roof-rail airbags
are designed to help reduce the risk
of full or partial ejection in rollover
events, although no system can
prevent all such ejections.
But airbags would not help in many
types of collisions, primarily
because the occupant’s motion is
not toward those airbags. SeeWhen
Should an Airbag Inflate? on
page 1-51for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.What Will You See After
an Airbag Inates?
After the frontal airbags and
seat-mounted side impact airbags
inate, they quickly deate, so
quickly that some people may not
even realize an airbag inated.
Roof-rail airbags may still be at least
partially inated for some time
after they deploy. Some components
of the airbag module may be hot
for several minutes. For location of
the airbag modules, seeWhat
Makes an Airbag Inflate? on
page 1-53.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There
may be some smoke and dust
coming from the vents in the
deated airbags. Airbag ination
does not prevent the driver
from seeing out of the windshield or
being able to steer the vehicle,
nor does it prevent people from
leaving the vehicle.
{CAUTION
When an airbag inates, there may
be dust in the air. This dust could
cause breathing problems for
people with a history of asthma or
other breathing trouble. To avoid
this, everyone in the vehicle should
get out as soon as it is safe to do
so. If you have breathing problems
but cannot get out of the vehicle
after an airbag inates, then get
fresh air by opening a window or a
door. If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors,
turn the interior lamps on, and turn
the hazard warning ashers on
when the airbags inate. You can
lock the doors, turn the interior
lamps off, and turn the hazard
warning ashers off by using the
controls for those features.
