PRESSURE WASHING
Cleaning the engine compartment with a high

VEHICLE MAINTENANCE
An authorized dealer has the qualified service
personnel, special tools, and equipment to
perform all service operations in an expert
manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
NOTE:
Intentional tampering with emissions control
sy
stems may void your warranty and could result in
civil penalties being assessed against you.
ENGINE OIL
Engine Oil Selection — Gasoline 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-12633.
NOTE:
Hemi engines (6.4L) at times can tick right after
st
artup 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.
Engine Oil Selection — Diesel Engine
For best performance and maximum protection
under all types of operating conditions, the
manufacturer only recommends engine oils that
are API CK-4 certified and meet the requirements
of the manufacturer. Use Mopar® or an equivalent
oil meeting the manufacturer Material Standard

ries contain lead and lead compounds. Wash

If a “fast charger” is used while the battery is
