124 STARTING AND OPERATING
4WD LOW — If Equipped
AutoPark will be disabled when operating the
vehicle in 4WD LOW.
The message AutoPark Disabled” will be
displayed in the instrument cluster.
Additional customer warnings will be given
when both of these conditions are met:
Vehicle is not in PARK
Driver’s door is ajar
The message AutoPark Not Engaged” will be
displayed in the instrument cluster. A warning
chime will continue until you shift the vehicle
into PARK or the driver’s door is closed.
ALWAYS DO A VISUAL CHECK
that your vehicle
is in PARK by looking for the "P" in the
instrument cluster display and on the gear
selector. As an added precaution, always apply
the parking brake when exiting the vehicle.
IF ENGINE FAILS TO START
If the engine fails to start after you have
followed the "Normal Starting" procedure and
has not experienced an extended park
condition (i.e., parked for more than 30 days), it
may be flooded. Push the accelerator pedal all
the way to the floor and hold it there while the
engine is cranking. This should clear any excess
fuel in case the engine is flooded. The starter
motor will engage automatically, run for
10 seconds, and then disengage. Once this
occurs, release the accelerator pedal and brake
pedal, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
COLD WEATHER OPERATION (BELOW
22°F O
R 30°C)
To ensure reliable starting at these
temperatures, use of an externally powered
electric engine block heater (available from an
authorized dealer) is recommended.
AFTER 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 standard 110-115 Volt AC
electrical outlet with a grounded, three-wire
extension cord.
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 310.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
10 seconds at a time. Wait 10 to 15 seconds
before trying again.
