If Engine Fails To Start

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 con-
verter 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. Refer to
"Jump-Starting Procedure" in "In Case Of
Emergency" for further information.

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 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
ambient temperatures below -20°F (-29°C), the
engine block heater is required.
The engine block heater cord is routed under
the hood, behind to the driver's side headlamp.
Follow the steps below to properly use the
engine block heater:
1. Locate the engine block heater cord (behind
the driver's side headlamp).
2. Undo the Velcro strap that secures the
heater cord in place.
3. Pull the cord to the front of the vehicle and
plug it into a grounded, three-wire extension
cord.
4. After the vehicle is running, reattach the cord
to the Velcro strap and properly stow away
behind the driver's side headlamp.
NOTE:
• The engine block heater cord is a factory
installed option. If your vehicle is not
equipped, heater cords are available from
your authorized Mopar dealer.
• The engine block heater will require 110 Volts
AC and 6.5 Amps to activate the heater
element.
• The engine block heater must be plugged in
at least one hour to have an adequate warm-
ing effect on the engine.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause elec-
trocution.
ENGINE BREAK-IN
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle) in
your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws contributes to
a good break-in. Wide-open throttle acceleration
in low gear can be detrimental and should be
avoided.
