STARTING THE ENGINE
1. Turn the key to 5 (START)
without pressing the accelerator
pedal and release as soon as the
engine starts. The key will return
to 4 (ON).
2. If the engine does not start
within five seconds, wait ten
seconds and try again.If your
vehicle is equipped with a 3.0L
Vulcan engine,and does not start
in two attempts in ambient
temperatures of ±20ÉC (±4ÉF) and
below, depress the accelerator
approximately 1/3 of the way down
and try again.
3. If the engine does not start in
two attempts OR if the
temperature is below -12ÉC (10ÉF),
depress the accelerator and start
the engine while holding the
accelerator down. Release the
accelerator when the engine starts.
4. After idling for a few seconds,
apply the brake and release the
parking brake.
Using the engine block heater
(if equipped)
An engine block heater warms the
engine coolant, which improves
starting, warms up the engine
faster and allows the
heater-defroster system to respond

quickly. They are strongly
recommended if you live in a
region where temperatures reach
-23ÉC (-10ÉF) or below.
For best results, plug the heater in
at least three hours before starting
the vehicle. Using the heater for
longer than three hours will not
harm the engine, so 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
Although odorless and colorless,
carbon monoxide is present in
exhaust fumes. Take precautions
to avoid its dangerous effects.
If you ever smell exhaust
fumes of any kind inside
your vehicle, have your dealer
inspect and fix your vehicle
immediately. Do not drive if you
smell exhaust fumes. These
fumes are harmful and could kill
you.
Have the exhaust and body
ventilation systems checked
whenever:
²the vehicle is raised for service

²the sound of the exhaust system
changes
²the vehicle has been damaged in
a collision
Important ventilating
information
If the engine is idling while the
vehicle is stopped in an open area
for long periods of time, open the
windows at least 2.5 cm (one
inch).
Adjust the heating or air
conditioning (if equipped) to bring
in fresh air.
Improve vehicle ventilation by
keeping all air inlet vents clear of
snow, leaves and other debris.

normal driving and should not be
noticeable to the driver.
To avoid injury, never run
the engine with one wheel
off the ground, such as when
changing a tire.
AIR SUSPENSION SYSTEM (IF
EQUIPPED)
The air suspension system is
designed to improve ride, handling
and general vehicle performance
for static, on and off-road driving
conditions.
²The load leveling feature of the
air suspension automatically
keeps the vehicle at a constant
level if a load is added or
removed from the vehicle.
²The height adjustment feature
automatically controls the
vehicle height over a range of
approximately 5 cm (2 inches)
based on vehicle speed, ignition
position and selection of two or
four-wheel drive modes.

If your vehicle gets stuck in mud
or snow it may be rocked out by
shifting from forward and reverse
gears in a steady pattern. Press
lightly on the accelerator in each
gear.
Do not rock the vehicle for
more than a few minutes. The
transmission and tires may be
damaged or the engine may
overheat.

more engine braking than
(Overdrive) and is useful when:
²driving with a heavy load
²towing a trailer up or down
steep hills
²additional engine downhill
braking is desired. If towing a
trailer, refer toDriving while

2 (Second)
Use 2 (Second) to start-up on
slippery roads or to provide
additional engine braking on
downgrades.
1 (First)
Use 1 (Low) to provide maximum
engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
(Overdrive). Selecting 1 (Low)
at higher speeds causes the
transmission to shift to a lower
gear, and will shift to 1 (Low) after
vehicle decelerates to the proper
speed.
MANUAL TRANSMISSION
OPERATION (IF EQUIPPED)
Using the clutch
Vehicles equipped with a manual
transmission have a starter
interlock that prevents cranking
the engine unless the clutch pedal
is fully depressed.
When starting a vehicle with a
manual transmission, you must:

pressing down slowly on the
accelerator pedal.
²Do not drive with your foot
resting on the clutch pedal and
do not use the clutch to hold
your vehicle at a standstill while
waiting on a hill. These actions
will seriously reduce clutch life.
