82STARTING AND OPERATING
ENGINE BREAK-IN RECOMMENDATIONS —
3.6L & 5.7L
A long break-in period is not required for the
drivetrain (engine, transmission, clutch, and rear
axle) in your new 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. However, wide-open throttle acceleration
in low gear can be detrimental and should be
avoided.
The engine oil, transmission fluid, and axle
lubricant installed at the factory are high-quality
and energy-conserving. Oil, fluid, and lubricant
changes should be consistent with anticipated
climate and conditions under which vehicle
operations will occur. For the recommended
viscosity and quality grades Ú page 306.
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
and not interpreted as an indication of difficulty.
Please check your oil level with the engine oil indi -
cator often during the break in period. Add oil as
required.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the gear
selector in the PARK or REVERSE (manual
transmission only) position.
When the parking brake is applied and the ignition
switch is in the ON/RUN position, the Brake
Warning Light in the instrument cluster will
illuminate.
NOTE:
When the parking brake is applied and the
transmission is placed in gear, the Brake
Warning Light will flash. If vehicle speed is
detected, a chime will sound to alert the driver.
Fully release the parking brake before
attempting to move the vehicle.
This light only shows that the parking brake is
applied. It does not show the degree of brake
application. When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade. For
vehicles equipped with an automatic transmission,
apply the parking brake before placing the gear
selector in PARK, otherwise the load on the
transmission locking mechanism may make it
difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever
the driver is not in the vehicle.
Manual Transmission — If Equipped
The foot operated parking brake is positioned
below the lower left corner of the instrument panel.
To release the parking brake, pull the parking
brake release handle.

CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

SERVICING AND MAINTENANCE255
NOTE:Intentional tampering with emissions control
systems may void your warranty and could result in
civil penalties being assessed against you.
ENGINE OIL
Engine Oil Selection — 3.6L And 5.7L
Engine
For best performance and maximum protection
under all types of operating conditions, the
manufacturer only recommends engine oils that
are API Certified and meet the requirements of the
manufacturer Material Standard MS-6395.
NOTE:Hemi engines (5.7L) at times can tick right after
startup and then quiet down after approximately
30 seconds. This is normal and will not harm the
engine. This characteristic can be caused by short
drive cycles: for example, if the vehicle is started
then shut off after driving a short distance. Upon
restarting, you may experience a ticking sound. Other causes could be if the vehicle is unused for
an extended period of time, incorrect oil, extended
oil changes or extended idling. If the engine
continues to tick or if the Malfunction Indicator
Light (MIL) comes on, see the nearest authorized
dealer.
American Petroleum Institute (API) Engine
Oil Identification Symbol
This symbol means that the oil has been
certified by the American Petroleum
Institute (API). The manufacturer only
recommends API Certified engine oils.
This symbol certifies 0W-20, 5W-20, 0W-30,
5W-30 and 10W-30 engine oils.
Synthetic Engine Oils
You may use synthetic engine oils provided the
recommended oil quality requirements are met,
and the recommended maintenance intervals for
oil and filter changes are followed.
Synthetic engine oils which do not have both the
engine oil certification mark and the correct SAE
viscosity grade number should not be used.
Shaker Hood — If Equipped
Shaker Hood Oil Filler
For vehicles equipped with a “Shaker Hood”, the
upper scoop will need to be removed so that oil can
be properly added to the engine.
To do this, use the following procedure:
1. Remove the four nuts with the Shaker tool located in the glove compartment.
2. Lift off the upper scoop.
NOTE:Be sure to clean off all debris around or inside of
the Shaker assembly.
3. Locate the oil fill cover in base assembly to expose the oil fill cap.
4. Remove oil fill cap to add oil.
5. Reinstall Shaker assembly.
WARNING!
You can be badly injured working on or around a
motor vehicle. Only do service work for which
you have the knowledge and the proper
equipment. If you have any doubt about your
ability to perform a service job, take your vehicle
to a competent mechanic.
CAUTION!
Do not use chemical flushes in your engine oil as
the chemicals can damage your engine. Such
damage is not covered by the New Vehicle
Limited Warranty.
