4-Door Utility
About Driving Your Vehicle
As with other vehicles of this type, failure to operate
this vehicle correctly may result in loss of control or an
accident. Be sure to read the “on-pavement” and
“off-road” driving guidelines in this manual.
(See “Your Driving, the Road and Your Vehicle” and
“Off-Road Driving with Your Four-Wheel-Drive
Vehicle” in the Index.)
How to Use this Manual
Many people read their owner’s manual from beginning
to end when they first receive their new vehicle. If you do
this, it will help you learn about the features and controls
for your vehicle. In this manual, you’ll find that pictures
and words work together to explain things quickly.
Safety Warnings and Symbols
You will find a number of safety cautions in this book.
We use a box and the word CAUTION to tell you
about things that could hurt you if you were to ignore
the warning.
CAUTION:
These mean there is something that could hurt
you or other people.
In the caution area, we tell you what the hazard is.
Then we tell you what to do to help avoid or reduce the
hazard. Please read these cautions. If you don’t, you or
others could be hurt.

viii
You will also find a circle
with a slash through it in
this book. This safety
symbol means “Don’t,”
“Don’t do this” or “Don’t
let this happen.”
Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could damage
your vehicle.
In the notice area, we tell you about something that can
damage your vehicle. Many times, this damage would
not be covered by your warranty, and it could be costly.
But the notice will tell you what to do to help avoid
the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different
colors or in different words.
You’ll also see warning labels on your vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle may be equipped with components and
labels that use symbols instead of text. Symbols, used on
your vehicle, are shown along with the text describing
the operation or information relating to a specific
component, control, message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator reference the following
topics in the index:
D “Engine Compartment Overview”
D “Instrument Panel”
D “Comfort Controls”
D “Audio Systems”
Also see “Warning Lights and Gages” in the Index.
Here are some examples of symbols you may find on
your vehicle:

Seats and Seat Controls
This section tells you about the manual and power
seats -- how to adjust them, and also about the reclining
front seatbacks, memory seats, lumbar adjustments and
heated seats.
Manual Front Seat
CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver’s seat while the vehicle is
moving. The sudden movement could startle and
confuse you, or make you push a pedal when you
don’t want to. Adjust the driver’s seat only when
the vehicle is not moving.
Pull up on the lever located under the front of the
manual seat to unlock it. Slide the seat to where you
want it and release the lever. Then try to move the
seat with your body to make sure the seat is locked
into place.
Power Seats (If Equipped)
If you have this feature,
the power seat controls are
located on the outboard side
of the front seat cushions.
D Move the front of the seat control up or down to
adjust the front portion of the cushion.
D Move the rear of the seat control up or down to
adjust the rear portion of the cushion.

1-3
D Lift up or push down on the center of the seat control
to move the entire seat up or down.
D To move the seat forward or rearward, slide the seat
control forward or rearward.
D To recline the seatback, press the vertical control
rearward. To raise the seatback, press the vertical
control forward.
Manual Lumbar Control
This control is located on the outboard side of the seat.
Turn the knob counterclockwise to increase lumbar
support and clockwise to decrease lumbar support.
Four-Way Power Lumbar Control
(If Equipped)
If your vehicle has this
feature, the driver’s and
passenger’s seatback
lumbar support can be
adjusted four ways by
moving a single control
located on the outboard
side of the seat cushions.
To increase or decrease support, hold the control
forward or rearward. To move the lumbar up or down,
hold the control up or down.
Keep in mind that as your seating position changes,
as it may during long trips, so should the position of
your lumbar support. Adjust the seat as needed.

1-4
Memory Seat (If Equipped)
If your vehicle has this
feature the controls are
located on the driver’s door,
and are used to program and
recall memory settings for
the driver’s seating and
outside mirror positions.
Adjust the driver’s seat (including the seatback recliner
and lumbar) and both of the outside mirrors to the
desired position. Then press and hold button 1
(for driver 1) for three seconds. A chime will sound
to let you know that the position has been stored.
A second mirror and seating position can be
programmed by repeating the procedure with a
second driver and pressing button 2 for three seconds.
Each time button 1 or 2 is pressed and released while
the vehicle is in PARK (P), the memory position will
be recalled. Each time a memory button is pressed,
a single chime will sound.
If you use the unlock button on the remote keyless entry
transmitter to enter your vehicle, the preset driver’s seat
and mirror positions will be recalled if programmed to
do so through the Driver Information Center (DIC).
The numbers on the back of the transmitters, 1 or 2,
correspond to the numbers on the memory controls.
The seat and mirror positions can also be recalled by
placing the key in the ignition if programmed to do
so through the Driver Information Center (DIC).
To stop recall movement of the memory feature at
any time, press one of the power seat controls or
memory buttons.

1-5
Two personalized exit positions can be set by first
recalling the driver’s position (by pressing 1 or 2), then
positioning the seat in the desired exit position for that
driver. Then press and hold the button with the exit
symbol for three seconds. A chime will sound to let you
know that the position has been stored. With the vehicle
in PARK (P), the exit position for that driver can be
recalled by pressing the exit button. The mirrors,
power lumbar and recline positions will not be stored
or recalled for the exit positions.
Programming for automatic seat and mirror movement
can be done through the Driver Information Center
(DIC). You can choose to either select or not select
automatic seat and mirror movement by using the
remote keyless entry transmitter, by placing your
key in the ignition, or when exiting the vehicle. For
programming information, see “Vehicle Programming
and Personalization Features” in the Index.
Heated Front Seats (Option)
Your vehicle may have
heated front seats. The
buttons used to control this
feature are located on the
front door armrests. The
engine must be running
for the heated seat feature
to work.
The horizontal button with the heated seat symbol
is used to control the temperature settings high,
medium and low. Press the button to cycle through the
temperature settings and to turn the heated seat off. An
indicator light will glow beside the temperature selected.
The low setting warms the seatback and cushion until
the seat temperature is near body temperature. The
medium and high settings heat the seatback and seat
cushion to a slightly higher temperature. You will be
able to feel heat in about two minutes.
To heat only the seatback, press the vertical button with
the heated seatback symbol. Press the vertical button
again to heat the whole seat.
The feature will shut off automatically when the ignition
is turned off.

1-6
Reclining Front Seatbacks
If your vehicle has a manual recliner, lift the lever
located on the outboard side of the seat and push the
seatback rearward to recline the seatback. To return the
seatback to the normal position, lift the lever without
pushing rearward on the seatback and the seatback
will move forward.
If your vehicle has power seat controls, the vertical
power seat control described earlier allows the seatback
to recline.
But don’t have a seatback reclined if your vehicle
is moving.

1-7
CAUTION:
Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts can’t do their job when
you’re reclined like this.
The shoulder belt can’t do its job. In a crash, you
could go into it, receiving neck or other injuries.
The lap belt can’t do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety
belt properly.
Head Restraints
Slide the head restraint up or down so that the top of the
restraint is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.
On some models, the head restraints tilt forward and
rearward also.
The head restraints lock into place when raised.
To release the head restraint and lower it, press the
tab located on the top of the seatback.

1-8
Rear Seats
Your vehicle has a folding rear seat which lets you fold
the seatbacks down for more cargo space.
Pull up on the tab located where the seat cushion meets
the seatback to fold the seat cushion up and out of
the way. This will allow the seatback to fold flat and
increase the cargo area.
The rear seatback handles
are located on the outboard
side of the rear seatbacks.
Pull the seatback toward you as you lift up on the handle.
The head restraint will automatically fold out of the way
when the seatback is folded down.
To raise the seatbacks, lift up the seatbacks and push
on them until they lock into the upright position.
Push and pull on the seatbacks to make sure that they
are latched securely. Then fold the bottom seat cushion
back into place.
