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 will influence when the “Oil Change
Required” message is displayed. Severe Operating Condi-
tions 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 possible, within the next 500
miles (805 km).
Your 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
your authorized dealer, the message can be reset by
referring to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel”.NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km), twelve 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.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and off
road environment or is operated predominately at idle or
only very low engine RPM’s. This type of vehicle use is
considered Severe Duty.
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 irregular wear,
even if it occurs before the oil indicator system turns on.
• Check the fluid levels of the coolant reservoir and brake
master cylinder, fill as needed.
• Check function of all interior and exterior lights.

WARNING!
•You can be badly injured working on or around a
motor vehicle. Do only service work for which you
have the knowledge and the right equipment. If you
have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.
• Failure to properly inspect and maintain your vehicle
could result in a component malfunction and effect
vehicle handling and performance. This could cause
an accident.
Heavy Duty Use Of The Vehicle
Change engine oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and off
road environment or is operated predominately at idle or
only very low engine RPM’s. This type of vehicle use is
considered Severe Duty.

Checking Oil Level
To assure 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 engine is shut OFF.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain the
oil level between the MIN and MAX markings on the
dipstick. Adding one quart or one liter of oil when the
reading is at the MIN mark will result in a MAX reading on
these engines.
CAUTION!
•Overfilling or underfilling will cause oil aeration, or
loss of oil pressure. This could damage your engine.
• Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
Adding Washer Fluid
The fluid reservoir is located in the front of the engine
compartment. Be sure to check the fluid level in the
reservoir at regular intervals. Fill the reservoir with wind-
shield washer solvent (not radiator antifreeze) and operate
the system for a few seconds to flush out the residual
washer fluid.
