CHECKING OIL LEVEL — 3.6L AND 5.7L
E
NGINE
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 month. 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 three 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.
NOTE:
Always maintain the oil level within the cross -
hatch markings on the dipstick.
Adding 1 Quart (1.0 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.
CHECKING OIL LEVEL — 6.2L
S
UPERCHARGED ENGINE AND 6.4L
E
NGINE
To ensure proper engine lubrication, the engine
oil must be maintained at the correct level.
Check the oil level at regular intervals, such as
once a month. The best time to check the
engine oil level is about five minutes after a fully
warmed engine is shut off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Maintain the oil level in the “SAFE”
range. Adding 1.0 Quart (1 Liter) of oil when the
reading is at the bottom of the “SAFE” range will
result in an oil level at the top of the “SAFE”
range on these engines.
ADDING WASHER FLUID
The windshield washer fluid reservoir is located
in the front of the engine compartment. Be sure
to check the fluid level at regular intervals. Fill
the reservoir with windshield washer solvent
(not radiator antifreeze) and operate the system
for a few seconds to flush out the residual
water.
When refilling the washer fluid reservoir, apply
some washer fluid to a cloth or towel and wipe
the wiper blades clean. 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.
The fluid reservoir will hold nearly 1 Gallon
(4 Liters) of washer fluid when the message
“Low Washer Fluid” appears in the instrument
cluster.CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine.
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.
