SERVICING AND MAINTENANCE

HECKING

EVEL

To ensure proper engine lubrication, the engine oil

must be maintained at the correct level. Check the

oil level at regular intervals, such as every fuel

stop. The best time to check the engine oil level is

about five minutes after a fully warmed up engine

is shut off.
Checking the oil while the vehicle is on level ground

will improve the accuracy of the oil level readings.
There are four possible dipstick types:



Crosshatched zone.



Crosshatched zone marked SAFE.



Crosshatched zone marked with MIN at the low

end of the range and MAX at the high end of the

range.



Crosshatched zone marked with dimples at the

MIN and the MAX ends of the range.

NOTE:

Always maintain the oil level within the crosshatch

markings on the dipstick.

Adding 1 quart (1 liter) of oil when the reading is at

the low end of the dipstick range will raise the oil

level to the high end of the range marking.
NOTE:

Always maintain the oil level within the crosshatch

markings on the dipstick.
NOTE:

Use care when filling under hood fluids such as

engine oil, washer fluid, antifreeze, etc., to

minimize spillage onto the top of the engine. Any

excess fluid that is spilled onto the top of the

engine should be removed using compressed air

or an absorbent cloth.

DDING

ASHER

LUID

The instrument cluster display will indicate when

the washer fluid level is low. When the sensor

detects a low fluid level, the windshield will light on

the vehicle graphic outline and the “WASHER

FLUID LOW” message will be displayed.

The fluid reservoir for the windshield washers and

the rear window washer is shared. The fluid

reservoir is located in the engine compartment, be

sure to check the fluid level at regular intervals. Fill

the reservoir with windshield washer solvent only

(not radiator antifreeze). When refilling the washer

fluid reservoir, take some washer fluid and apply it

to a cloth or towel and wipe clean the wiper blades,

this will help blade performance. To prevent

freeze-up of your windshield washer system in cold

weather, select a solution or mixture that meets or

exceeds the temperature range of your climate.

This rating information can be found on most

washer fluid containers.
NOTE:

Use care when filling under hood fluids such as

engine oil, washer fluid, antifreeze, etc., to

minimize spillage onto the top of the engine. Any

excess fluid that is spilled onto the top of the

engine should be removed using compressed air

or an absorbent cloth.

WARNING!

Commercially available windshield washer

solvents are flammable. They could ignite and

burn you. Care must be exercised when filling or

working around the washer solution.

Engine Oil Selection

Use only the manufacturer's recommended fluid

page 405.

NOTE:

Hemi engines 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)

Approved Engine Oil

These symbols mean that the oil has been certified

by the API. The manufacturer only recommends API

trademark 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.

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 numbers 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 product and its performance may be

impaired by supplemental additives.

Disposing Of Used Engine Oil And Oil

Filters
