3. Continue to press and hold the trip odometer resetstem to scroll through all of the available
languages.
The available languages are ENGLISH (default),
FRANCAIS (French), ESPANOL (Spanish), and
NO CHANGE.
4. Once the desired language is displayed, release the trip odometer reset stem to set your choice.
Trip Odometer
Press the trip odometer reset stem until TRIP displays.
This display shows the current distance traveled in
either miles (mi) or kilometers (km) since the last reset
for the trip odometer.
The trip odometer can be reset to zero by pressing and
holding the trip odometer reset stem while the trip
odometer is displayed.
The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to the
number of miles (kilometers) driven since the ignition
was last turned on. This can be used if the trip
odometer is not reset at the beginning of the trip.
To use the retro-active reset feature, press and hold
the trip odometer reset stem for at least four seconds.
The trip odometer will display the number of miles (mi)
or kilometers (km) driven since the ignition was last
turned on and the vehicle was moving. Once the vehicle
begins moving, the trip odometer will accumulate mileage. For example, if the vehicle was driven
5 miles (8 km) before it is started again, and then the
retro-active reset feature is activated, the display will
show 5 miles (8 km). As the vehicle begins moving,
the display will then increase to 5.1 miles (8.2 km),
5.2 miles (8.4 km), etc.
Transmission Temperature
Press the trip odometer reset stem until TRANS TEMP
displays. This display shows the temperature of the
automatic transmission fluid in either degrees
Fahrenheit (°F) or degrees Celsius (°C).
Trailer Gain and Output
On vehicles with the Integrated Trailer Brake Control
(ITBC) system, the trailer brake display appears in the
DIC. Press the trip odometer reset stem until TRAILER
GAIN and OUTPUT display.
TRAILER GAIN shows the trailer gain setting. This
setting can be adjusted from 0.0 to 10.0 with either a
trailer connected or disconnected. To adjust this setting,
see
“Integrated Trailer Brake Control System” under
Towing a Trailer
on page 5‑42for more information.
OUTPUT shows the power output to the trailer anytime
a trailer with electric brakes is connected. Output is
displayed in 0 to 10 bars. Dashes may appear in the
OUTPUT display. See “Integrated Trailer Brake Control
System” underTowing a Trailer
on page 5‑42for more
information.

TRAILER CONNECTED
On vehicles with the Integrated Trailer Brake
Control (ITBC) system, this message displays briefly
when a trailer with electric brakes is first connected to
the vehicle.
This message clears itself after several seconds. This
message also clears if you acknowledge it. After this
message clears, the TRAILER GAIN/OUTPUT display
appears in the DIC.
See“TRAILER GAIN/OUTPUT” underDIC Operation
and Displays (Using DIC Buttons)
on page 4‑43or DIC

Control System” underTowing a Traileron page 5‑42for more information.
TRANSMISSION HOT IDLE ENGINE
Notice: If you drive your vehicle while the
transmission fluid is overheating and the
transmission temperature warning is displayed on
the instrument panel cluster and/or DIC, you can
damage the transmission. This could lead to costly
repairs that would not be covered by your warranty.
Do not drive your vehicle with overheated
transmission fluid or while the transmission
temperature warning is displayed. This message displays along with a sound if the
transmission fluid in the vehicle gets hot. Driving with
the transmission fluid temperature high can cause
damage to the vehicle. Stop the vehicle and let it idle to
allow the transmission to cool. This message clears and
the chime stops when the fluid temperature reaches a
safe level.
TURN SIGNAL ON
This message displays and a chime sounds if a turn
signal is left on for 3/4 of a mile (1.2 km). Move the turn
signal/multifunction lever to the off position.
WASHER FLUID LOW ADD FLUID
This message displays when the windshield washer
fluid is low. Fill the windshield washer fluid reservoir as
soon as possible. See
Engine Compartment Overview
on page 6‑14for the location of the windshield washer
fluid reservoir. Also, see Windshield Washer Fluidon
page 6‑37for more information.

Traction Control Operation
The traction control system is part of the StabiliTrak
system. Traction control limits wheel spin by reducing
engine power to the wheels (engine speed
management) and by applying brakes to each individual
wheel (brake-traction control) as necessary.
The traction control system is enabled automatically
when the vehicle is started. It will activate and the
StabiliTrak light will flash if it senses that any of the
wheels are spinning or beginning to lose traction while
driving. If traction control is turned off, only the
brake-traction control portion of traction control will
work. The engine speed management will be disabled.
In this mode, engine power is not reduced automatically
and the driven wheels can spin more freely. This can
cause the brake-traction control to activate constantly.
Notice:If the wheel(s) of one axle is allowed to spin
excessively while the StabiliTrak, ABS and brake
warning lights and any relevant DIC messages are
displayed, the transfer case could be damaged. The
repairs would not be covered by the vehicle
warranty. Reduce engine power and do not spin the
wheel(s) excessively while these lights and
messages are displayed. The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, a reduction in
acceleration may be noticed, or a noise or vibration may
be heard. This is normal.
If cruise control is being used when the system
activates, the StabiliTrak light will flash and cruise
control will automatically disengage. Cruise control may
be reengaged when road conditions allow. See
Cruise
Control on page 4‑8.
StabiliTrak may also turn off automatically if it
determines that a problem exists with the system. If the
problem does not clear itself after restarting the vehicle,
see your dealer/retailer for service.
Locking Rear Axle
Vehicles with a locking rear axle can give more traction
on snow, mud, ice, sand or gravel. It works like a
standard axle most of the time, but when traction is low,
this feature will allow the rear wheel with the most
traction to move the vehicle.

.Sound the horn as you approach the top of the hill
to let opposing traffic know you are there.
.Use headlamps even during the day to make the
vehicle more visible to oncoming traffic.
{WARNING:
Driving to the top (crest) of a hill at full speed can
cause an accident. There could be a drop-off,
embankment, cliff, or even another vehicle. You
could be seriously injured or killed. As you near
the top of a hill, slow down and stay alert.
If the vehicle stalls, or is about to stall, and you cannot
make it up the hill:
.Push the brake pedal to stop the vehicle and keep
it from rolling backwards and apply the parking
brake.
.If the engine is still running, shift the transmission
to R (Reverse), release the parking brake, and
slowly back down the hill in R (Reverse).
.If the engine has stopped running, you need to
restart it. With the brake pedal pressed and the
parking brake still applied, shift the transmission to
P (Park) and restart the engine. Then, shift to R (Reverse), release the parking brake, and slowly
back down the hill as straight as possible in
R (Reverse).
.While backing down the hill, put your left hand on
the steering wheel at the 12 o'clock position so you
can tell if the wheels are straight and can
maneuver as you back down. It is best to back
down the hill with the wheels straight rather than in
the left or right direction. Turning the wheel too far
to the left or right will increase the possibility of a
rollover.
Things not to do if the vehicle stalls, or is about to stall,
when going up a hill:
.Never attempt to prevent a stall by shifting into
N (Neutral) to rev-up the engine and regain forward
momentum. This will not work. The vehicle can roll
backward very quickly and could go out of control.
.Never try to turn around if about to stall when
going up a hill. If the hill is steep enough to stall
the vehicle, it is steep enough to cause it to roll
over. If you cannot make it up the hill, back straight
down the hill.
If, after stalling, you try to back down the hill and decide
you just cannot do it, set the parking brake, put your
transmission in P (Park), and turn off the engine. Leave
the vehicle and go get some help. Exit on the uphill side
and stay clear of the path the vehicle would take if it
rolled downhill.

Driving Downhill
When off-roading takes you downhill, consider:
.How steep is the downhill? Will I be able to
maintain vehicle control?
.What is the surface like? Smooth? Rough?
Slippery? Hard-packed dirt? Gravel?
.Are there hidden surface obstacles? Ruts? Logs?
Boulders?
.What is at the bottom of the hill? Is there a hidden
creek bank or even a river bottom with large
rocks?
If you decide you can go down a hill safely, try to keep
the vehicle headed straight down. Use a low gear so
engine drag can help the brakes so they do not have to
do all the work. Descend slowly, keeping the vehicle
under control at all times.
{WARNING:
Heavy braking when going down a hill can cause
your brakes to overheat and fade. This could
cause loss of control and a serious accident.
Apply the brakes lightly when descending a hill
and use a low gear to keep vehicle speed under
control. Things not to do when driving down a hill:
.When driving downhill, avoid turns that take you
across the incline of the hill. A hill that is not too
steep to drive down might be too steep to drive
across. The vehicle could roll over.
.Never go downhill with the transmission in
N (Neutral), called free-wheeling. The brakes will
have to do all the work and could overheat
and fade.
Vehicles are much more likely to stall when going uphill,
but if it happens when going downhill: 1. Stop the vehicle by applying the regular brakes and apply the parking brake.
2. Shift to P (Park) and, while still braking, restart the engine.
3. Shift back to a low gear, release the parking brake, and drive straight down.
4. If the engine will not start, get out and get help.

Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, find a safe
place to park your vehicle and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving—scan the road ahead
and to the sides.
.Check the rearview mirror and vehicle instruments
often.
Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on flat or rolling terrain. Tips for driving in
these conditions include:
.Keep the vehicle serviced and in good shape.
.Check all fluid levels and brakes, tires, cooling
system, and transmission.
.Going down steep or long hills, shift to a
lower gear.
{WARNING:
If you do not shift down, the brakes could get so
hot that they would not work well. You would then
have poor braking or even none going down a hill.
You could crash. Shift down to let the engine
assist the brakes on a steep downhill slope.
5-26

Rocking Your Vehicle to Get It Out
Turn the steering wheel left and right to clear the area
around the front wheels. Turn off any traction or stability
system. Shift back and forth between R (Reverse) and a
forward gear, spinning the wheels as little as possible.
To prevent transmission wear, wait until the wheels stop
spinning before shifting gears. Release the accelerator
pedal while shifting, and press lightly on the accelerator
pedal when the transmission is in gear. Slowly spinning
the wheels in the forward and reverse directions causes
a rocking motion that could free the vehicle. If that does
not get the vehicle out after a few tries, it might need to
be towed out. Recovery hooks can be used, if the
vehicle has them. If the vehicle does need to be towed
out, seeTowing Your Vehicle on page 5‑37.
Recovery Hooks
{WARNING:
These hooks, when used, are under a lot of force.
Always pull the vehicle straight out. Never pull on
the hooks at a sideways angle. The hooks could
break off and you or others could be injured from
the chain or cable snapping back.
Notice:Never use recovery hooks to tow the
vehicle. Your vehicle could be damaged and it
would not be covered by warranty.
Your vehicle has recovery hooks at the front of the
vehicle. You can use them if you are stuck off-road and
need to be pulled to some place where you can
continue driving.

Two-Wheel-Drive Vehicles
Dinghy Towing
Notice:If a two-wheel-drive vehicle is towed with all
four wheels on the ground, the transmission could
be damaged. The repairs would not be covered by
the vehicle warranty. Do not tow a two-wheel-drive
vehicle with all four wheels on the ground.
Two-wheel-drive vehicles should not be towed with all
four wheels on the ground. Two-wheel-drive
transmissions have no provisions for internal lubrication
while being towed.
To dolly tow a two‐wheel‐drive vehicle, the vehicle must
be towed with the rear wheels on the dolly. See “Dolly
Towing (Rear Wheels Off the Ground)” following.
