some washer fluid and apply it to a cloth or towel and
wipe clean the wiper blades; this will help blade perfor-
mance.
To prevent freeze-up of your windshield washer system
in cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This
rating information can be found on most washer fluid
containers.
WARNING!
Commercial windshield washer solvents are flam-
mable. They could ignite and burn you. Care must be
exercised when filling or working around the washer
solution.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, have the
exhaust system inspected each time the vehicle is raised
for lubrication or oil change. Replace as required.

of driving. At normal operating temperature, the fluid
cannot be held comfortably between the fingertips.
Use the following procedure to check the transmission
fluid level properly:
1. Park the vehicle on level ground.
2. Remove the engine cover by pulling it up off the
mounting studs (two in the front and two in the rear).
3. Run the engine at idle speed and normal operating
temperature.
4. Fully apply the parking brake, and press the brake
pedal.
5. Place the shift lever momentarily into each gear posi-
tion (allowing time for the transmission to fully en-
gage in each position), ending with the transmission in
PARK.
6. Remove the dipstick, wipe it clean and reinsert it until
seated.
7. Remove the dipstick again and note the fluid level on
both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid
if the actual level is at or above the hole. The fluid level
should be between the HOT (upper) reference holes on
the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube
to bring it to the proper level.Do not overfill.Use
ONLY the specified fluid (refer to#Fluids, Lubricants,
and Genuine Parts#for fluid specifications). After
adding any quantity of oil through the dipstick tube,
wait a minimum of two minutes for the oil to fully
drain into the transmission before rechecking the fluid
level.

MAINTENANCE SCHEDULE
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 “Change Oil” or “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).
On Electronic Vehicle Information Center (EVIC) equipped
vehicles, “Oil Change Required” will be displayed in the
EVIC and a single chime will sound, indicating that an oil
change is necessary.
On Non-EVIC equipped vehicles, “Change Oil” will flash
in the instrument cluster odometer and a single chime
will sound, indicating that an oil change is necessary.
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 the steps described under “Instrument Clus-
ter Descriptions” or “Electronic Vehicle Information Cen-
ter (EVIC)” in “Understanding Your Instrument Panel”
for further information.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment. This
type of vehicle use is considered Severe Duty
