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 improves starting, warms up the engine faster
and allows the heater-defroster system to respond
quickly. 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. 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.

To release the parking
brake, the brake handle
may need to be pulled
up slightly to release
pressure before
pushing in the button.
Push the button on the
end of the parking
brake handle and push the handle down as far as
possible. Driving with the parking brake applied will
cause the brakes to wear out quickly and reduce fuel
economy.
Anti-lock brake system (ABS)
On vehicles equipped with an anti-lock braking
system (ABS), 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. The
accompanying illustration depicts the advantage of
an ABS equipped vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with
loss of front braking traction.

ABSwarning lampABS
TheABSwarning lamp in 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 lamp illuminates, have your vehicle
serviced immediately.)
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 full 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 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.
Hydraulic brake booster system (Hydroboost)
The Hydroboost system receives fluid pressure from
the power steering pump to provide power assist
during braking.
The sound of the pump operating may be heard by
the driver, but this is a normal characteristic of the
system.
For Hydroboost-equipped vehicles operating under
normal conditions, the noise of the fluid flowing

surfaces.The system operates by detecting and
controlling wheel spin. The system borrows many of
the electronic and mechanical elements already
present in the anti-lock braking system (ABS).
Wheel-speed sensors allow excess rear wheel spin to
be detected by the Traction Control
portion of the
ABS computer. Any excessive wheel spin is
controlled by automatically applying and releasing
the rear brakes in conjunction with engine torque
reductions. Engine torque reduction is realized via
the fully electronic spark and fuel injection systems.
This process is very sensitive to driving conditions
and very fast acting. The rear wheels“search”for
optimum traction several times a second and
adjustments are made accordingly.
The Traction Control
system will allow your
vehicle to make better use of available traction on
slippery surfaces. The system is a driver aid which
makes your vehicle easier to handle primarily on
snow, ice covered and gravel roads.
During Traction
Control
operation,
the traction control
active light will
illuminate, you may hear an electric motor type of
sound coming from the engine compartment and the
engine will not“rev-up”when you push further on
the accelerator. This is normal system behavior.
The Traction Control

on/off switch, located
below the radio,
illuminates when the
system is OFF. The
Traction Control
system will revert to the ON
position every time the ignition is turned OFF and
ON.
If you should become stuck in snow or ice or on a
very slippery road surface, try switching the Traction
Control
system off. This may allow excess wheel
spin to“dig”the vehicle out and enable a successful
“rocking”maneuver.
Driving
143

If a system fault is detected the OFF indicator lamp
on the traction control switch will be illuminated and
your vehicle should be serviced.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery
surfaces, particularly when one wheel is on a poor
traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle.
Extended use of other than the manufacturer’s
specified size tires on a Traction-Lok rear axle could
result in a permanent reduction in effectiveness.
This loss of effectiveness does not affect normal
driving and should not be noticeable to the driver.
To reduce the risk of injury, never run the
engine with one wheel off the ground, such
as when changing a tire.
AUTOMATIC TRANSMISSION OPERATION
(IF EQUIPPED)
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 ignition key to
LOCK, then remove the key.
2. Insert the key and turn it to OFF.Apply the
brake pedal and shift to N (Neutral).
In the ignition OFF position, the automatic
transmission shift lever can be moved from
the P (Park) position without the brake pedal
depressed. To avoid unwanted vehicle movement,
always set the parking brake.
Driving
144

3. Start the vehicle.
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 the
Roadside emergencieschapter.
Do not drive your vehicle until you verify
that the brakelamps are working.
If your vehicle gets stuck in mud or snow it may be
rocked out by shifting from forward and reverse
gears, stopping between shifts, in a steady pattern.
Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at
normal operating temperature or damage to
the transmission may occur.
Do not rock the vehicle for more than a few
minutes or damage to the transmission and
tires may occur or the engine may overheat.
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.

Understanding gearshift positions
P (Park)
Always come to a
complete stop before
shifting into P (Park).
Make sure the gearshift
lever is securely
latched in P (Park).
This position locks the
transmission and
prevents the rear
wheels from turning.
Always set the parking brake fully and make
sure the gearshift lever is latched in P
(Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
R (Reverse)
With the gearshift lever
in R (Reverse), the
vehicle will move
backward. Always come
to a complete stop
before shifting into and
out of R (Reverse).
N (Neutral)
With the gearshift lever
in N (Neutral), the
vehicle can be started
and is free to roll. Hold
the brake pedal down
while in this gear.

MANUAL TRANSMISSION OPERATION
(IF EQUIPPED)
Using the clutch
Vehicles equipped with a manual transmission have a
starter interlock that prevents cranking of the
engine unless the clutch pedal is fully depressed.
When starting a vehicle with a manual transmission,
you must:
1. Make sure the
parking brake is fully
set.
2. Depress the clutch
pedal fully.
3. Put the gearshift
lever in neutral.
4. Start the engine and
letitidleforafew
seconds.
5. Depress the brake
pedal.
6. Release the parking
brake.
7. Move the gearshift
lever to the desired
gear.
8. Release the brake
pedal.
9. Slowly release the
clutch pedal while slowly pressing down on the
accelerator pedal.
•Do 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 greatly reduce clutch life.
