TARTING
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
page 134. 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 for at
least one hour to have an adequate warming effect
before starting the engine.
The engine block heater cord is located:
5.7L & 6.4L Engine — Bundled and fastened to
the injector harness.
ENGINE BREAK-IN RECOMMENDATIONS
An initial break-in period is recommended for the
powertrain (engine, transmission, axle, etc.) in your
vehicle. Following the guidelines below will
contribute to improved longevity, fuel economy,
and performance.
Drive moderately during the first 100 miles
(160 km). After that, for the first 500 miles
(800 km), avoid long periods at constant speed.
Varying speed, engine RPM, and throttle position is
desirable.
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 auto
-
matic 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
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.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.
