SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indicator
system will remind you that it is time to take your
vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent short-trips,
trailer tow, extremely hot or cold ambient
temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is
displayed. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for fleet
customers.
Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look for
unusual wear or damage.
Check the fluid levels of the coolant reservoir,
brake master cylinder and fill as needed.
Check function of all interior and exterior lights.

CHECKING OIL LEVEL
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 (1.0 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.
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.
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 illuminate and the “Washer Fluid
Low” message will display.
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.
CAUTION!
Do not travel with the windshield washer fluid
reservoir empty: the windshield washers are
essential for improving visibility.

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.
Refer to the “Maintenance Plan” for the proper
maintenance intervals. 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
automatically 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. All passenger vehicle tires must conform
to Federal safety requirements in
addition to these grades.
TREADWEAR
The Treadwear grade is a comparative
rating, based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half times as well on
the government course as a tire graded
100. The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
