STARTING
Positions of the ignition
1. OFF/LOCK, shuts off the engine
and all accessories/locks the steering
wheel, gearshift lever and allows key
removal.
2. ACC, allows the electrical
accessories such as the radio to
operate while the engine is not
running. This position also unlocks
the steering wheel.
3. ON, all electrical circuits
operational. Warning lights illuminated. Key position when driving.
4. START, cranks the engine. Release the key as soon as the engine
starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, avoid pressing the accelerator
before or during starting. Only use the accelerator when you have
difficulty starting the engine. For more information on starting the
vehicle, refer toStarting the enginein this chapter.
Extended idling at high engine speeds can produce very high
temperatures in the engine and exhaust system, creating the risk
of fire or other damage.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats upthe engine
compartment and exhaust system, which can start a fire.
Do not start your vehicle in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic. Always open the garage door
before you start the engine. SeeGuarding against exhaust fumesin
this chapter for more instructions.

3. If the temperature is below -12° C (10° F) and the engine does not
start in 15 seconds on the first try, turn the key OFF and wait 10
seconds and try again. If the engine does not start in two attempts, press
the accelerator pedal all the way to floor and hold. Turn the key to
START position.
4. When the engine starts, release the key, then release the accelerator
pedal gradually as the engine speeds up.
5. After idling for a few seconds, apply the brake, shift into gear and
drive.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant which aids in starting
and heater/defroster performance. Use of an engine block heater is
strongly recommended if you live in a region where temperatures reach
-23° C (-10° F) or below. For best results, plug the heater in at least
three hours before starting the vehicle. The heater can be plugged in the
night before starting the vehicle.
To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
Driving

operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or
“continuous squeal” sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
If you are driving down a long or steephill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.
Anti-lock brake system (ABS)
On ABS-equipped vehicles, a noise from the hydraulic pump motor and
pulsation in the pedal may be observed during ABS braking events. Pedal
pulsation coupled with noise while braking under panic conditions or on
loose gravel, bumps, wet or snowy roads is normal and indicates proper
functioning of the vehicle’s anti-lock brake system. The ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal. If a
malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
The ABS operates by detecting the onset of wheel lockup during brake
applications and compensates for this tendency. The wheels are
prevented from locking even when the brakes are firmly applied.
Using ABS
•In an emergency or when maximum efficiency from the four-wheel
ABS is required, apply continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing you to retain steering
control of your vehicle and, providing there is sufficient space, will
enable you to avoid obstacles and bring the vehicle to a controlled
stop.
•The anti-lock system does not always reduce stopping distance.
Always leave enough room between your vehicle and the vehicle in
front of you to stop.
•We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
Driving

Brake Assist (if equipped)
The Brake Assist system provides full braking force during panic braking
situations. It detects a rapid application of the brake pedal and
maximizes the amount of brake booster assist, helping the driver to
achieve maximum braking pressure. Once a panic brake application is
detected, the system will remain activated as long as the brake pedal is
depressed. The system is deactivated by releasing the brake pedal.
When the system activates, the brake pedal will travel with very little
effort; this is normal.
ABS warning lamp
ABS
TheABSwarning lampin the instrument cluster momentarily illuminates
when the ignition is turned to the ON position. If the light does not
illuminate momentarily at start up, remains on or continues to flash, the
ABS needs to be serviced.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. (If your brake warning lampilluminates, have your vehicle
serviced immediately.)
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
The BRAKE warning lampin the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned ON) until the
parking brake is released.

Always set the parking brake fully and make sure that the
gearshift is securely latched in P (Park).
The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
ADVANCETRAC
STABILITY ENHANCEMENT SYSTEM
(IF EQUIPPED)
The AdvanceTracsystem provides a stability enhancement feature as
well as a traction enhancement feature. It helps your vehicle maintain
traction, when driving on slippery and/or hilly road surfaces, by detecting
and controlling wheel spin. Excessive wheel spin is controlled by
momentarily reducing engine power and rapidly applying the anti-lock
brakes. The system is a driver aid which makes your vehicle easier to
handle primarily on snow and ice-covered roads.
If your vehicle should become stuck in deepsnow or mud, try switching
the AdvanceTracsystem off by pressing the AdvanceTracbutton.
This will allow your tires to “dig” for traction.
If the AdvanceTracsystem is activated and deactivated excessively in a
short period of time, the brake portion of the system will shut down to
allow the brakes to cool down. A limited AdvanceTracfunction using
only engine power reduction will still help control the wheels from
over-spinning. When the brakes have cooled down, the system will again
function normally. Anti-lock braking is not affected by this condition and
will function normally during the cool-down period.

Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions, such as
slower speeds and increased stopping distance, should be taken when
driving a heavily loaded vehicle.
Your vehicle has the capability to haul more cargo and people than most
passenger cars. Depending upon the type and placement of the load,
hauling people and cargo may raise the center of gravity of the vehicle.
Use extra caution while becoming familiar with your vehicle. Know the
capabilities and limitations of both you as a driver and your vehicle.
AUTOMATIC TRANSMISSION OPERATION
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed:
1. Apply the parking brake, turn the ignition to LOCK, then remove the
key.
2. Locate the access panel on the
driver side of the floor console.
Using a screwdriver (or equivalent),
pry the access panel off the floor
console.
Driving

3. Using the screwdriver (or
equivalent), push the white plastic
override mechanism (located behind
the bracket) toward the roof of the
vehicle as shown in the illustration.
4. Move the gearshift lever back to N (Neutral) (two places from P
[Park]).
5. Start the vehicle and release the parking brake.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
emergencieschapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.

Driving with a 5–speed automatic transmission
Your transmission is equipped with an adaptive learning strategy found in
the vehicle computer. This feature is designed to increase durability, and
provide consistent shift feel over the life of the vehicle. A new vehicle or
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation. Additionally, whenever the battery is
disconnected or a new battery is installed, the strategy must relearn.
Understanding gearshift positions
Hold the brake pedal down while you move the gearshift lever
from P (Park) to another position. If you do not hold the brake
pedal down, your vehicle may move unexpectedly and injure someone.
P (Park)
This position locks the transmission
and prevents the rear wheels from
turning.
To put your vehicle in gear:
•Start the engine
•Depress the brake pedal
•Move the gearshift lever into the
desired gear
To put your vehicle in P (Park):
•Come to a complete stop
•Move the gearshift lever and securely latch it in P (Park)
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.

The system automatically turns on when the gear selector is placed in R
(Reverse) and the ignition is ON. A control in the message center allows
the driver to disable the system only when the ignition is ON, and the
gear selector is in R (Reverse). Refer toMessage centerin theDriver
Controlschapter for more information.
Keep the Rear Park Assist sensors (located on the rear
bumper/fascia) free from snow, ice and large accumulations of
dirt (do not clean the sensors with sharp objects). If the sensors
are covered, it will affect the accuracy of the system.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with an All Wheel Drive (AWD) transfer
case. With the AWD option, power is supplied to all four wheels
automatically with no need to shift between two-wheel drive and
four-wheel drive. If your vehicle is equipped with the AdvanceTrac
stability enhancement feature, you can change AWD modes, if desired,
by selecting AWD options through the message center.
For the lubricant specification and refill capacity of the AWD transfer
case refer toMaintenance and specificationschapter.
If your vehicle is equipped with AWD, a spare tire of a different
size than the road tires should never be used. Such a tire could
make the vehicle difficult to control as well as result in damage to
driveline components.
Utility and four-wheel drive vehicles arenotdesigned for
cornering at speeds as high as passenger cars any more than
low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharpturns or abrupt maneuvers in these
vehicles.
The following sections,Normal operation,Autolock operationand
Disabling AWD, apply only to vehicles which allow the driver to change
AWD modes through the message center.
Driving

Normal operation (vehicles equipped with AdvanceTrac
only)
During normal operation:
•the AWD system is in AWD AUTO mode (AWD LOCKED will
illuminate in the message center for four seconds when you first start
your vehicle). The AWD LOCKED indicator in the instrument cluster
will also come on.
•AWD AUTO mode can be overridden by pressing SETUP in the
message center. When you first press SETUP, AWD <AUTO> will be
displayed, then if you press RESET within four seconds of pressing
SETUP, AWD <LOCKED> will be displayed. AWD <LOCKED> provides
power to all four wheels constantly which allows you to operate your
vehicle in severe winter or off-road conditions such as deepsnow, ice
or shallow sand. It is not recommended that you use AWD <LOCKED>
on dry pavement.
•AWD <LOCKED> can be cancelled by pressing RESET in the message
center. (The AWD LOCKED display in the message center will then
turn off and the display will return to AWD <AUTO> for four seconds
when the shift is complete.)
Autolock operation (vehicles equipped with AdvanceTrac
only)
If the AWD system begins to overheat, the system will place itself in the
Autolock mode:
•the AWD LOCKED indicator light will illuminate in the instrument
cluster and AWD DISABLED <LOCKED> will be displayed in the
message center.
•AWD LOCKED will be displayed in the message center for four
seconds and a warning chime will sound. This condition may clear
without any action being taken by the driver.
•the AWD LOCKED indicator light in the instrument cluster will turn
off when the AWD system cools down.
•When the system is sufficiently cooled down, AWD AUTO RESTORED
will appear in the message center for four seconds and a warning
chime will sound.
Disabling AWD (vehicles equipped with AdvanceTrac
only)
When a problem is detected in the AWD system:
•the AWD LOCKED indicator light in the instrument cluster will flash
eight times every two minutes in the message center.
•The message center will then display AWD DISABLED for four
seconds, then SEE OWNER’S MANUAL. A warning chime will also
