Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down. It also tells you about
reclining front seatbacks and head restraints.
Power Seats
Horizontal Control: You can adjust your vehicle's front
seats with the horizontal control located on the outboard
edge of each front seat.
Raise or lower the front of the seat by raising or
lowering the forward edge of the control. Raise or lower
the rear of the seat by raising or lowering the rear edge
of the control.
Move the seat forward or rearward by moving the
whole control toward the front or toward the rear of
the vehicle.
Moving the whole control up or down raises or lowers
the entire seat cushion.

1-4 Heated Front Seats
The control for the driver's
side heated seat is located
on the driver's side door
panel. The control for the
passenger's side heated seat
is located on the passenger's
side door panel.
The ignition must be in RUN for this feature to operate.
To activate the heated seats, press the button once for the
HI heat setting. Press the button again for the LO heat
setting. To turn off the heated seats, press the button a third
time. An indicator light on the button will illuminate for
each heat setting anytime the heated seats are operating.
The heated front seats will be canceled after the ignition
is turned to OFF. If you still want to use the heated front
seat feature after you restart your vehicle, you will need
to press the heated seat button again.
You vehicle also has rear heated seats. See the section
on ªRear Heated Seatsº later in this section for
more information.
Reclining Front Seatbacks
Your vehicles front seatbacks have a recline feature.
Vertical Control: You can use the vertical control to
adjust the angle of the seatback. Move the reclining front
seatback rearward or forward by moving the control
toward the rear or toward the front of the vehicle.

How does an air bag restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The air bag supplements the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant's upper body,
stopping the occupant more gradually. But the frontal air
bags would not help you in many types of collisions,
including rollovers, rear impacts, and side impacts,
primarily because an occupant's motion is not toward
the air bag. Side impact air bags would not help you in
many types of collisions, including frontal or near
frontal collisions, rollovers, and rear impacts, primarily
because an occupant's motion is not toward those air
bags. Air bags should never be regarded as anything
more than a supplement to safety belts, and then only in
moderate to severe frontal or near
-frontal collisions for
the driver's and right front passenger's frontal air bags,
and only in moderate to severe side collisions for the
driver's and right front passenger's side impact air bags.What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module
-- the
steering wheel hub for the driver's air bag, the
instrument panel for the right front passenger's bag, the
side of the seatback closest to the door for the driver and
right front passenger's side impact air bags
-- will be
hot for a short time. The parts of the bag that come into
contact with you may be warm, but not too hot to touch.
There will be some smoke and dust coming from the
vents in the deflated air bags. Air bag inflation doesn't
prevent the driver from seeing or being able to steer the
vehicle, nor does it stop people from leaving the vehicle.

CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child's hip
bones are still so small that the vehicle's regular
safety belt may not remain low on the hip bones,
as it should. Instead, it may settle up around the
child's abdomen. In a crash, the belt would apply
force on a body area that's unprotected by any
bony structure. This alone could cause serious or
fatal injuries. Young children always should be
secured in appropriate child restraints.
Restraint Systems for Children
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed to
restrain or position a child on a continuous flat surface.
Make sure that the infant's head rests toward the center
of the vehicle.

1-72
CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can't properly spread the impact forces.
In a crash, the two children can be crushed
together and seriously injured. A belt must be
used by only one person at a time.
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt is
very close to the child's face or neck?
A:Move the child toward the center of the vehicle, but
be sure that the shoulder belt still is on the child's
shoulder, so that in a crash the child's upper body
would have the restraint that belts provide. If the
child is sitting in a rear seat outside position, see
ªRear Safety Belt Comfort Guidesº in the Index.
If the child is so small that the shoulder belt is still
very close to the child's face or neck, you might
want to place the child in a seat that has a lap belt,
if your vehicle has one.

New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the long
run if you follow these guidelines:

Keep your speed at 55 mph (88 km/h) or
less for the first 500 miles (805 km).

Don't drive at any one speed
-- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.
Ignition Positions
You can use your key to turn your ignition switch to
five different positions.
ACCESSORY (A): This position lets you use things
like the radio, power windows and the windshield
wipers when the engine is off. Push in the key and turn
it toward you.
