Starting the engine
1. Turn the key to 4
(ON) without turning
the key to 5 (START).
2. Turn the key to 5
(START), then release
the key as soon as the
engine starts.
Excessive cranking
could damage the starter.
Note:If the engine does not start within five
seconds on the first try, turn the key to 3 (OFF),
wait 10 seconds and try again. If the engine still fails
to start, press the accelerator to the floor and try
again; this will allow the engine to crank with the
fuel shut off in case the engine is flooded with fuel.
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 reduce the risk of 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.
