SERVICING AND MAINTENANCE
SC\b\fED 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 kmyf.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 kmyf
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
MAINTENANCE PLAN
Refer to the Maintenance Plan for the required
maintenance intervals.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change oil and filter.
Rotate the tires. Rotate at the first sign of
irregular wear, even if it occurs before the
oil indicator system turns on.
Inspect battery and clean and tighten termi -
nals as required.
Inspect the CV/Universal joints.
Inspect brake pads, shoes, rotors, drums,
hoses and parking brake.
Inspect engine cooling system protection
and hoses.
Inspect exhaust system.

the engine is overheated. Do not loosen or
remove the cap to cool an overheated

injury, do not remove the pressure cap
while the system is hot or under pressure.
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
