How to Use This Manual
Many people read the owner manual from
beginning to end when they rst receive their
new vehicle. If this is done, it can help you learn
about the features and controls for the vehicle.
Pictures and words work together in the owner
manual to explain things.
Index
A good place to quickly locate information about
the vehicle is the Index in the back of the manual.
It is an alphabetical list of what is in the manual
and the page number where it can be found.
Safety Warnings and Symbols
There are a number of safety cautions in this
book. We use a box and the word CAUTION to
tell 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 do not, you or others could be hurt.
You will also nd a
circle with a slash
through it in this book.
This safety symbol
means “Do Not,”
“Do Not do this” or
“Do Not let this happen.”

Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not be
covered by your vehicle’s warranty, and it could
be costly. But the notice will tell 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.
There are also warning labels on the vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown
along with the text describing the operation or
information relating to a specic component,
control, message, gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3
Climate Controls in Section 3
Warning Lights, Gages, and Indicators in
Section 3
Audio System(s) in Section 3

{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.
Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and
ash the hazard warning ashers when the airbags
inate. You can lock the doors again, turn the
interior lamps off, and turn off the hazard warning
ashers by using the controls for those features.In many crashes severe enough to inate the
airbag, windshields are broken by vehicle
deformation. Additional windshield breakage may
also occur from the right front passenger airbag.Airbags are designed to inate only once.
After an airbag inates, you will need some
new parts for your airbag system. If you do not
get them, the airbag system will not be there
to help protect you in another crash. A new
system will include airbag modules and
possibly other parts. The service manual for
your vehicle covers the need to replace
other parts.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection
and Event Data Recorders on page 538.
Let only qualied technicians work on the
airbag system. Improper service can mean
that an airbag system will not work properly.
See your dealer for service.

4m(Four-Wheel High):This setting should be
used when you need extra traction, such as
on snowy or icy roads or in most off-road
situations. This setting also engages your front
axle to help drive your vehicle.
4
n(Four-Wheel Low):This setting also
engages your front axle and delivers extra torque.
It sends maximum power to all four wheels.
You might choose this setting if you are driving
off-road in deep sand, deep mud, and climbing or
descending steep hills.
{CAUTION:
Shifting the transfer case to NEUTRAL
can cause your vehicle to roll even if the
transmission is in PARK (P). You or
someone else could be seriously injured.
Be sure to set the parking brake before
placing the transfer case in NEUTRAL.
SeeParking Brake on page 126.NEUTRAL:Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle.
SeeRecreational Vehicle Towing on page 355for
more information.
An indicator light in the knob will show you which
position the transfer case is in. The indicator
lights will come on briey when you turn on the
ignition and one will stay on. If the lights do
not come on, you should take your vehicle to your
dealer for service. An indicator light will ash
while shifting the transfer case. It will stay on when
the shift is complete. If for some reason the
transfer case cannot make a requested shift, it will
return to the last chosen setting.
If the service Four-Wheel Drive Warning Light on
the instrument panel cluster stays on, you
should take your vehicle to your dealer for service.
SeeService Four-Wheel Drive Warning Light on
page 216for further information.
123

Parking Brake
To set the parking brake, hold the regular brake
pedal down with your foot and pull up on the
parking brake lever located between the seats.
If the ignition is on, the brake system warning light
on the instrument panel cluster will come on.
SeeBrake System Warning Light on page 206.To release the parking brake, hold the regular
brake pedal down. Pull the parking brake lever up
until you can press in the button at the end of
the lever. Hold the button in as you move
the parking brake lever all the way down.
Notice:Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake system
parts. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
If you are towing a trailer and you must park on a
hill, seeTowing a Trailer on page 362.

Outside Manual Mirrors
If the vehicle has the manual outside mirrors,
adjust each outside mirror so that a little of
the vehicle and the area behind it can be seen
while sitting in a comfortable, driving position.
Both mirrors can be manually folded inward
by pulling them towards the vehicle. Push the
mirrors away from the vehicle, to the normal
position, before driving.
Outside Power Mirrors
Your vehicle may have this feature. The power
mirror control is located on the driver’s door.
Turn the knob counterclockwise or clockwise to
adjust the driver’s or passenger’s mirror so
that you can see a little of the side of your vehicle.
After adjusting the position of the mirrors, turn
the knob to the center position so that the mirrors
cannot move.
If the travel position in any direction of the mirror is
reached, it will enter a ratcheting mode. This action
is harmless. It is a warning that the mirror can go no
further. To stop this action, back the mirror up by
moving the knob in the opposite direction.The mirrors can be manually folded inward to
prevent damage when going through an automatic
car wash. To fold, push the mirror toward the
vehicle. To return the mirror to its original position,
push outward. Be sure to return both mirrors to
their original unfolded position before driving.
Outside Curb View Assist Mirror
If the vehicle has this feature, the passenger’s
outside mirror will adjust to a preset tilt position
while the vehicle is in REVERSE (R) gear.
Curb view assist may be useful when you are
parallel parking. The mirror will return to normal
position when the vehicle is shifted out of
REVERSE (R) gear. Automatic mirror movement
in either direction will follow a short delay.
You may be able to turn this feature on or off
through the Driver Information Center (DIC). See
DIC Vehicle Customization on page 229.
