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,

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:

4. Check all battery terminals and
remove any excessive corrosion

1. Position the vehicles so that
they do not touch one another.
2. Switch off the engine. Switch off
any unnecessary electrical
equipment.
3. Connect the positive (+)
terminal of the discharged battery
(1) to the positive (+) terminal of
the booster battery (2).
4. Connect one end of the second
lead to the negative (-) terminal of
the booster battery (3) and the
other end to a metal part of the
engine to be started (4), not to the
negative (-) terminal of the
discharged battery.
5. Make sure that the jump leads
are clear of moving parts of the
engine.
Do not connect the end of
the second cable to the
negative (-) terminal of the
battery to be jumped. A spark
may cause an explosion of the
gases that surround the battery.
