SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GASOLINE
ENGINE
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. If a scheduled oil change is performed
by someone other than an authorized dealer, the
message can be reset by referring to the steps
described under Instrument Cluster Display
Ú page 101.
NOTE:
Under no circumstances should oil change
in
tervals exceed 8,000
miles (13,000 km),
1
2
months or 350 hours of engine run time,
wh
ichever 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 tire pressure and look for unusual wear
or damage. Rotate tires at the first sign of irreg-
ular wear, even if it occurs before the oil indi-
cator system turns on
Check the fluid levels of the coolant reservoir,
brake master cylinder and power steering and
fill as needed
Check function of all interior and exterior lights
