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.

4. Check all battery terminals and
remove any excessive corrosion
before you attach the battery
cables.
5. Turn the heater fan on in both
vehicles to protect any electrical
surges. Turn all other accessories
off.
Connecting the jumper cables
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.
