STARTING AND OPERATING 109
(Continued)
EXTREME COLD WEATHER
(B
ELOW 20°F OR 29°C)
To ensure reliable starting at these
temperatures, use of an externally powered
electric engine block heater (available from an
authorized dealer) is recommended.
EXTENDED PARK STARTING
NOTE:
Extended Park condition occurs when the
vehicle has not been started or driven for at
least 30 days.
1. Install a battery charger or jumper cables
to the battery to ensure a full battery
charge during the crank cycle.
2. Place the ignition in the START mode and
release it when the engine starts.
3. If the engine fails to start within 10 seconds,
place the ignition in the OFF mode, wait
10 to 15 seconds to allow the starter to
cool, then repeat the Extended Park
Starting procedure.
4. If the engine fails to start after eight
attempts, allow the starter to cool for
at least 10 minutes, then repeat the
procedure.
IF ENGINE FAILS TO START
A
FTER STARTING
The idle speed is controlled automatically, and
it will decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine and
permits quicker starts in cold weather.
Connect the cord to a 110-115 Volt AC electrical
outlet with a grounded, three-wire extension
cord.
For ambient temperatures below 0°F (-18°C),
the engine block heater is recommended for at
least an hour to have an adequate warming
effect on the engine. For ambient temperatures
below -20°F (-29°C), the engine block heater is
required for at least four hours to have an
adequate warming effect on the engine.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
WARNING!
Never pour fuel or other flammable liquid
into the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine has
started, ignite and damage the converter
and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly Ú page 351.
