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

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 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 3-47for further information.
Shifting Into 4HI (Four-Wheel High)
or A4WD (Automatic Four-Wheel Drive)
Turn the knob to 4HI or A4WD. This can be done at any
speed unless you are shifting out of 4LO. The indicator
light will ash while shifting. It will remain on when
the shift is complete.
Shifting Into 2HI (Two-Wheel High)
Turn the knob to 2HI. This can be done at any speed

2 mph (3.2 km/h) with the transmission in NEUTRAL (N).
The preferred method for shifting into 4LO is to have
your vehicle moving 1 or 2 mph (1.6 to 3.2 km/h).Turn the knob to 4LO. You must wait for the 4LO indicator
light to stop ashing and stay on before shifting the
transmission into gear.
If you turn the knob to 4LO when your vehicle is in
gear and/or moving, the 4LO indicator light will ash
for 30 seconds and not complete the shift unless your
vehicle is moving less than 2 mph (3.2 km/h) and
the transmission is in NEUTRAL (N). After 30 seconds,
the transfer case will return to the setting last chosen.

vehicle must be stopped or moving less than
2 mph (3.2 km/h) with the transmission in NEUTRAL (N)
and the engine running. The preferred method for
shifting out of 4LO is to have your vehicle moving
1 or 2 mph (1.6 to 3.2 km/h). Turn the knob to 4HI,
A4WD or 2HI. You must wait for the 4HI, A4WD, or
2HI indicator light to stop ashing and stay off before
shifting your transmission into gear.
If the knob is turned to 4HI, A4WD, or 2HI when your
vehicle is in gear and/or moving, the 4HI, A4WD, or
2HI indicator light will ash for 30 seconds. It will
not complete the shift unless your vehicle is moving
less than 2 mph (3.2 km/h) with the transmission
in NEUTRAL (N).

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 3-38.
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.

seeTowing a Trailer on page 4-55.
2-31

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
The vehicle may have this feature.
The 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.
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). SeeDIC Vehicle
Customization on page 3-56.

Your hazard warning ashers let you 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.
Your hazard warning ashers work no matter what
position your key is in, and even if the key is not in
the ignition.
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
signals will not work.

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

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 3-49.
