CHECKING OIL LEVEL — 3.0L ENGINES
The 3.0L engine does not have a traditional “dipstick” and
there is no need to manually check the oil level. If it is
desired to check engine oil level, it can be seen on the
instrument cluster display by navigating to the appropriate
screen under “Vehicle Information”. Use the up or
down arrow buttons within the steering wheel controls
to find the “Vehicle Information” menu. Then use the
right or left arrow buttons until you reach the “Oil
Level” sub-menu.
There is a white bar on the gauge which shows the oil level.
As long as the oil level is between the minimum and the
maximum it is safe to operate the vehicle. If the oil level is
either too high or too low, a red bar will be illuminated.
When the engine is in need of more oil, the Oil Level
Warning Light will illuminate. This warning will appear for
five seconds. Within the next 300 miles (500 km) you
should add 1 quart of manufacturer specified motor oil to
the engine
Úpage 376. This light will reappear every time the engine is started
until a safe level is detected. Continuing to operate the
vehicle without adding oil may result in a critically low oil
level and possible engine damage (see “Critically Low”
below).
NOTE:Use care when filling under hood fluids such as engine oil,
washer fluid, antifreeze, etc. to minimize spillage onto top
of engine. Any excess fluid that is spilled onto the top of
the engine should be removed using compressed air or an
absorbent cloth.
Oil Level Display - How To Refresh After Adding Oil
In vehicles equipped with the 3.0L engine, the oil level is
automatically monitored when the vehicle is parked on a
level surface, the oil is warm, and the engine has been off
four minutes. To refresh the oil level display (after a quart
of the correct oil has been added), follow this process:

Run the engine until the oil temperature is above
120°F (49°C).
 Park the vehicle on relatively level ground. 
Turn the engine off and wait four minutes. If you choose
to stay in the vehicle and want to listen to the radio
while waiting, it is acceptable to have the ignition
switch in any position (OFF or ON/RUN) as long as the
engine is not running.
 Start the engine and the new oil level will be available
in the Vehicle Information menu (accessible via the
navigation buttons on the steering wheel).
NOTE:
If the level indication is not updated after the previously
described procedure, repeat. The oil level measure -
ment is made every time the engine has been turned
off (after being warmed up) and on a level surface. If
you do not get a “new” reading after adding oil, find a
more “level” surface to measure. Most parking lots and
gas stations are sufficiently level, some driveways are
not.
 If you have added a quart of oil and the indicator is not
reading 3/4 or full, please contact an authorized dealer
for service.

WARNING!
Be aware the oil cap may be hot. Please use suitable
gloves. WARNING: risk of burns!
CAUTION!
Do not to add too much oil. Overfilling the oil may
damage the engine.

SERVICING AND MAINTENANCE317
NOTE:
After adding oil to the engine, always reinstall the oil
cap securely by rotating clockwise until it stops. Never
run the engine without the oil fill cap as this could
cause an oil leak.
 Because the oil level is automatically detected only
when the engine has been off and restarted (after four
minutes), the system cannot immediately detect a
sudden drop in oil level while driving (for example, if the
oil pan starts to leak due to damage during an off-road
event).
CHECKING OIL LEVEL — 5.7L & 6.4L
E
NGINES
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 qt (1 L) 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.
ADDING WASHER FLUID
The instrument cluster display will indicate when the
washer fluid level is low. When the sensor detects a low
fluid level, the Low Washer Fluid Warning Light will turn on
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 top
of engine. Any excess fluid that is spilled onto the top of
the engine should be removed using compressed air or an
absorbent cloth.
CAUTION!
If the “Critically Low or Critically High” Oil Level Warning
Light is illuminated, the following steps should be
taken:
Critically Low: add two quarts of manufacturer speci -
fied oil as soon as possible
Úpage 376. Continuing
to operate the vehicle with “Critically Low” oil level
may damage the engine.
 Critically High: contact an authorized dealer for
service. Continuing to operate the vehicle with “Criti -
cally High” oil level may damage the engine.
Do not use any oils that are not manufacturer specified
and API approved.
Used engine oil and oil filters contain substances which
are harmful to the environment. When oil and filters are
changed contact an authorized dealer and dispose of in
a safe and responsible manner.
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.

TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off-Road
type tires. Rotation will increase tread life, help to
maintain mud, snow, and wet traction levels, and
contribute to a smooth, quiet ride.
For the proper maintenance intervals
Úpage 310. More
frequent rotation is permissible if desired. The reasons for
any rapid or unusual wear should be corrected prior to
rotation being performed.
NOTE:The premium Tire Pressure Monitoring System will auto -
matically locate the pressure values displayed in the
correct vehicle position following a tire rotation.
The suggested rotation method is the “rearward cross”
shown in the following diagram.

Tire Rotation (Rearward Cross)

DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
 Because of restricted traction device clearance
between tires and other suspension components, it
is important that only traction devices in good condi -
tion are used. Broken devices can cause serious
damage. Stop the vehicle immediately if noise occurs
that could indicate device breakage. Remove the
damaged parts of the device before further use.
 Install device as tightly as possible and then
retighten after driving about ½ mile (0.8 km).
 Do not exceed 30 mph (48 km/h).
 Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
 Do not drive for a prolonged period on dry pavement.
 Observe the traction device manufacturer’s instruc -
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested
operating speed of the device manufacturer’s if it is
less than 30 mph (48 km/h).
 Do not use traction devices on a compact spare tire.
