After Starting
The idle speed is controlled automatically, and it will

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 an 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 warming effect on the engine.

5. Position the new Sealant Bottle (1) in the housing so thatthe Sealant Hose (6) aligns with the hose slot in the front
of the housing. Push the bottle into the housing. An
audible click will be heard indicating the bottle is locked
into place.
6. Verify that the cap is installed on the fitting at the end of the Sealant Hose (6) and return the hose to its storage
area (located on the bottom of the air pump).
7. Return the Tire Service Kit to its storage location in the vehicle.
JUMP STARTING
If your vehicle has a discharged battery, it can be jump
started using a set of jumper cables and a battery in another
vehicle or by using a portable battery booster pack. Jump

the manufacturer ’s operating instructions and precautions.

Jump Starting Procedure

Conditions that would require replacement:
•Rib chunking (one or more ribs has separated from belt
body)
• Rib or belt wear
• Longitudinal belt cracking (cracks between two ribs)
• Belt slips
• “Groove jumping (belt does not maintain correct posi-
tion on pulley)
• Belt broken (note: identify and correct problem before
new belt is installed) •
Noise (objectionable squeal, squeak, or rumble is heard
or felt while drive belt is in operation)
Some conditions can be caused by a faulty component such
as a belt pulley. Belt pulleys should be carefully inspected
for damage and proper alignment.
Belt replacement on some models requires the use of
special tools, we recommend having your vehicle serviced
at an authorized dealer.
Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
