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.”
iii

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

Four-Wheel Drive

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 3-39.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 4-56.

Passenger Airbag Indicator
The mirror may be equipped with a passenger airbag
indicator on the mirror glass, just above the buttons.
If the vehicle has this feature the mirror will display the
word ON, or an airbag symbol in Canada, when the
passenger airbag is enabled. For more information see
Passenger Sensing System on page 1-67
Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
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.

The hazard warning ashers warn others. They also let
police know you have a problem. Your front and rear
turn signal lamps will ash on and off.
The hazard warning
asher button is located
on top of the steering
column.
The hazard warning ashers work no matter what
ignition position the key is in, and even if the key is not

Press the button to make the front and rear turn signal
lamps ash on and off. Press the button again to
turn the ashers off.
When the hazard warning ashers are on, your turn

the side of the road about 300 feet (100 m) behind
your vehicle.
Horn

steering wheel pad.
Tilt Wheel
You should adjust the
steering wheel before you

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice.
Waiting to do repairs can be costly—and even
dangerous. So please get to know your warning lights
and gages. They’re a big help.
Your vehicle may also have a Driver Information Center
(DIC) that works along with the warning lights and
gages. SeeDriver Information Center (DIC) on
page 3-50.
