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 will influence when the “Oil Change 
Required” message is displayed. Severe 
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 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 “Instrument Cluster Display” in 
“Getting To Know Your Instrument Panel”.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.
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. 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

364SERVICING AND MAINTENANCE  
(Continued)
Maintain engine coolant (antifreeze) concen-
tration at a minimum of 50% OAT coolant 
(conforming to MS.90032) and distilled 
water for proper corrosion protection of your 
engine which contains aluminum compo -
nents.
Make sure that the coolant expansion bottle 
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your 
vehicle is equipped with air conditioning, 
keep the front of the condenser clean.
Do not change the thermostat for Summer or 
Winter operation. If replacement is ever 
necessary, install ONLY the correct type ther -
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze) 
performance, poor gas mileage, and 
increased emissions.
Brake System 
In order to ensure brake system performance, 
all brake system components should be 
inspected periodically. Refer to the 
“Maintenance Plan” in this section for the 
proper maintenance intervals.
Brake Master Cylinder
The fluid in the master cylinder should be 
checked when performing under hood services 
or immediately if the “Brake Warning Light” is 
illuminated.
Be sure to clean the top of the master cylinder 
area before removing the cap. If necessary, add 
fluid to bring the fluid level up to the requirements 
described on the brake fluid reservoir. With disc 
brakes, fluid level can be expected to fall as the 
brake pads wear. Brake fluid level should be 
checked when pads are replaced. However, low 
fluid level may be caused by a leak and a checkup 
may be needed.
Use only manufacturer's recommended brake 
fluid. Refer to “Fluids And Lubricants” in 
“Technical Specifications” for further information.
WARNING!
Riding the brakes can lead to brake failure 
and possibly a collision. Driving with your foot 
resting or riding on the brake pedal can result 
in abnormally high brake temperatures, 
excessive lining wear, and possible brake 
damage. You would not have your full braking 
capacity in an emergency.
WARNING!
Use only manufacturer's recommended 
brake fluid. Refer to “Fluids And Lubricants” 
in “Technical Specifications” for further infor-
mation. Using the wrong type of brake fluid 
can severely damage your brake system 
and/or impair its performance. The proper 
type of brake fluid for your vehicle is also 
identified on the original factory installed 
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter 
or moisture, use only new brake fluid or fluid 
that has been in a tightly closed container. 
Keep the master cylinder reservoir cap 
secured at all times. Brake fluid in a open 
container absorbs moisture from the air 
resulting in a lower boiling point. This may 
cause it to boil unexpectedly during hard or 
prolonged braking, resulting in sudden brake 
failure. This could result in a collision.
