transmission fluid in either degrees Fahrenheit (°F) or
degrees Celsius (°C).
Instantaneous Economy and Active Fuel
Management™Indicator
If your vehicle has this display, press the trip/fuel button
until INST ECON V8 displays. This display shows the
current fuel economy at a particular moment and will
change frequently as driving conditions change. This
display shows the instantaneous fuel economy in miles
per gallon (mpg) or liters per 100 kilometers (L/100 km).
Unlike average economy, this screen cannot be reset.
An Active Fuel Management indicator will display on the
right side of the DIC, while INST ECON displays on the
left side. Active Fuel Management allows the engine to
operate on either four or eight cylinders, depending on
your driving demands. When Active Fuel Management
is active, V4 will display on the DIC. When Active Fuel
Management is inactive, V8 will display. See Active
Fuel Management™
on page 3‑31for more
information.

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 5‑47for 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 5‑47for more
information.
Compass Zone Setting
This display allows for setting the compass zone. See
DIC Compasson page 4‑58for more information.

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 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.
Steering
Power Steering
If the vehicle is a Two‐mode Hybrid, see the Two‐mode
Hybrid manual for more information.
If power steering assist is lost because the engine stops
or the system is not functioning, the vehicle can be
steered but it will take more effort.
Steering Tips
It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and vehicle speed. While in a curve, speed is
the one factor that can be controlled.
If there is a need to reduce speed, do it before entering
the curve, while the front wheels are straight.

.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. If the vehicle has a transfer case with a
N (Neutral) position, do not shift the transfer case to
Neutral when you leave the vehicle. Leave it in
some gear.
{WARNING:
If the vehicle has the two‐speed automatic
transfer case, shifting the transfer case to
Neutral can cause your vehicle to roll even if the
transmission is in P (Park). This is because the
Neutral position on the transfer case overrides
the transmission. You or someone else could be
injured. If you are going to leave your vehicle, set
the parking brake and shift the transmission to
P (Park). But, if the vehicle has a two‐speed
automatic transfer case, do not shift the transfer
case to Neutral.

Rocking Your Vehicle to Get It Out
Turn the steering wheel left and right to clear the area
around the front wheels. For four-wheel-drive vehicles,
shift into Four‐Wheel High or, if the vehicle has a
two‐speed automatic transfer case, Four‐Wheel Low.
For vehicles with StabiliTrak
®, turn the traction control
part of the system off. 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, see Towing Your
Vehicle on page 5‑40.
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.

Dinghy Towing
Two-Wheel-Drive Vehicles and Four-Wheel
Drive Vehicles with a Single Speed
Automatic Transfer Case
Notice:If the vehicle is towed with all four wheels
on the ground, the drivetrain components could be
damaged. The repairs would not be covered by the
vehicle warranty. Do not tow the vehicle with all
four wheels on the ground. Two-wheel-drive vehicles and four-wheel drive vehicles
with a single speed automatic transfer case should
not be towed with all four wheels on the ground.
Two-wheel-drive transmissions have no provisions for
internal lubrication while being towed. Four-wheel drive
vehicles with a single speed automatic transfer case
have no neutral position and will spin the transmission
when the rear wheels turn.
5-41

Four-Wheel Drive Vehicles with a
Two Speed Automatic Transfer Case
Use the following procedure to dinghy tow a four-wheel
drive vehicle with a two speed automatic transfer case:1. Position the vehicle being towed behind the tow vehicle and shift the transmission to P (Park).
2. Turn the engine off and firmly set the parking brake.
3. Securely attach the vehicle being towed to the tow vehicle.
{WARNING:
Shifting a four-wheel-drive vehicle's transfer case
into N (Neutral) can cause the vehicle to roll even
if the transmission is in P (Park). The driver or
others could be injured. Make sure the parking
brake is firmly set before the transfer case is
shifted to N (Neutral).
4. Shift the transfer case to N (Neutral). See “Shifting
into Neutral” under“Four-Wheel Drive” for the
proper procedure to select the Neutral position for
the vehicle.
5. Release the parking brake only after the vehicle being towed is firmly attached to the towing
vehicle.
6. Turn the ignition to LOCK/OFF and remove the key —the steering wheel will still turn.
After towing, see “Shifting Out of Neutral” under
“Four-Wheel Drive” for the proper procedure to take the
vehicle out of the Neutral position.

Dolly Towing
Front Towing (Front Wheels Off the
Ground)
Two-Wheel-Drive Vehicles and Four-Wheel
Drive Vehicles with a Single Speed
Automatic Transfer Case
Notice:If a two-wheel drive vehicle or a four-wheel
drive vehicle with a single speed automatic transfer
case is towed with the rear wheels on the ground, the transmission could be damaged. The repairs
would not be covered by the vehicle warranty. Never
tow the vehicle with the rear wheels on the ground.
Two-wheel-drive vehicles and four-wheel drive vehicles
with a single speed automatic transfer case should
not be towed with the rear wheels on the ground.
Two-wheel-drive transmissions have no provisions for
internal lubrication while being towed. Four-wheel drive
vehicles with a single speed automatic transfer case
have no neutral position and will spin the transmission
when the rear wheels turn.
To dolly tow a two‐wheel‐drive vehicle or a four-wheel
drive vehicle with a single speed automatic transfer
case, the vehicle must be towed with the rear wheels
on the dolly. See
“Rear Towing (Rear Wheels Off the
Ground)” later in this section for more information.
