PRESSURE WASHING
Cleaning the engine compartment with a high pressure
washer is not recommended.

and connections however, the pressures generated
by these machines is such that complete protection
against water ingress cannot be guaranteed.

nel, special tools, and equipment to perform all service

ENGINE OIL
Engine Oil Selection — Gasoline Engine
Use only the manufacturer's recommended fluid
NOTE:
Hemi engines (6.4L) 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 dis-
tance. 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
Use only the manufacturer's recommended fluid
American Petroleum Institute (API)
Approved Engine Oil
These symbols mean that the oil has been certified by
the API. The manufacturer only recommends API trade-
mark oils.
The API Starburst trademark certifies
0W-20, 0W-30 and 5W-30 engine oils.
The API Donut trademark certifies
0W-40 and 5W-40 engine oil.
For diesel engines, oils with a high ash con-
tent may produce damaging deposits on cyl-
inder head valves and/or after-treatment system dam-
age. A maximum sulfated ash content of 1.00 mass %
is recommended for all oil used in the engine.
The same oil change interval is to be followed for syn-
thetic oil as for petroleum-based oil. Also, synthetic oil
must meet the same performance specifications as
petroleum oil.
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.
Synthetic Engine Oils
Your engine was designed for synthetic engine oils, only
use synthetic API approved engine oils.
Synthetic engine oils which do not have both the correct
API trademark and the correct SAE viscosity grade num-
bers should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against the
addition of any additives (other than leak detection
dyes) to the engine oil. Engine oil is an engineered prod-
uct and its performance may be impaired by supple-
mental additives.
