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
You can adjust the front seats with the controls located
on the side of the seat, next to the door.You can use the round center knob to move the seat to
where you want it. To raise the seat, move the knob up.
To lower the seat, move the knob down. To move the
seat forward, move the knob toward the front of the
vehicle. To move the seat rearward, move the knob
toward the rear of the vehicle.
You can also raise and lower the front and rear of the
seat. To raise the front of the seat, move the front lever
up. To lower the front of the seat, move the front lever
down. To raise the rear of the seat, move the rear lever
up. To lower the rear of the seat, move the rear
lever down.
The switch located at the front of this control panel
is for the power lumbar adjustment, which is
explained next.

1-6 Rear Seats
CAUTION:
If a head restraint is not installed on the seatback
or stored in the vehicle properly, it could be
thrown about the vehicle in a crash or sudden
maneuver. People in the vehicle could be injured.
Remove the head restraints only when you need
to fold the seat, and be sure that the head
restraints are stored securely in the appropriate
holes at the rear of the lower seat cushion. When
the seat is returned to the passenger position, be
sure the head restraints are installed properly.
Folding the Rear Seat
Your vehicle has a 60/40 rear seat, either side may be
folded down to give you more cargo space.
Before folding, place the latch portion of the center
safety belt in the center armrest. That way, the center
safety belt will be out of the way when the seat is folded
and also will be easily available for passengers to use
when the seat is returned to the passenger position. Also,
make sure that nothing is under or in front of the seat.
When the seat is folded, it will lay flat on the floor.
To fold the seat, pull up on
the strap loop at the rear of
the seat cushion.
Then, pull the seat cushion up and fold it forward.

The Certification/Tire label also tells you the maximum
weights for the front and rear axles, called Gross Axle
Weight Rating (GAWR). To find out the actual loads on
your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help
you with this. Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR for your vehicle, or the
GAWR for either the front or rear axle.
And, if you do have a heavy load, you should spread it out.
CAUTION:
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can
break, and it can change the way your vehicle
handles. These could cause you to lose control
and crash. Also, overloading can shorten the life
of your vehicle.
Using heavier suspension components to get added
durability might not change your weight ratings. Ask
your dealer to help you load your vehicle the right way.Your warranty does not cover parts or components that
fail because of overloading.
If you put things inside your vehicle
-- like suitcases,
tools, packages, or anything else
-- they go as fast as the
vehicle goes. If you have to stop or turn quickly, or if
there is a crash, they'll keep going.
CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or in
a crash.

Put things in the cargo area of your vehicle.
Try to spread the weight evenly.

Never stack heavier things, like suitcases,
inside the vehicle so that some of them are
above the tops of the seats.

Don't leave an unsecured child restraint in
your vehicle.

When you carry something inside the
vehicle, secure it whenever you can.

Don't leave a seat folded down unless you
need to.
