The starter motor will engage automatically, run for
10 seconds, and then disengage. Once this occurs, release
the accelerator pedal and the brake pedal, wait 10 to
15 seconds, then repeat the “Normal Starting” procedure.
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.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that
is located on the driver side of the Integrated Power
Module.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
