SCHEDULED MAINTENANCE — DIESEL
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 in
the instrument cluster. This means that ser-
vice is required for your vehicle. Operating
conditions such as frequent short-trips,
trailer tow, and extremely hot or cold ambient
temperatures will influence when the “Oil
Change Required” message is displayed. Se-
vere Operating Conditions can cause the
change oil message to illuminate as early as
3,500 miles (5,600 km) since last reset.
Have your vehicle serviced as soon as pos-
sible, within the next 500 miles (805 km).
NOTE:
Under no circumstances should oil change
intervals exceed 18,500 miles (29,773 km)
or twelve months, whichever comes first.

• 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 reser-
voir, brake master cylinder, and power
steering, and fill as needed
• Check function of all interior and exterior
lights
