The engine block heater must be plugged in at least one
hour to have an adequate effect on the engine.
The engine block heater cord is bundled under the hood
between the headlight assembly and the Totally Integrated
Power Module (Fuse Box) on the driver’s side of the
vehicle.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80
or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. For the recom-
mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE: A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and not
interpreted as a problem. Please check your oil level with
the engine oil indicator often during the break in period.
Add oil as required.6

Towing Tips
Before setting out on a trip, practice turning, stopping, and
backing up the trailer in an area located away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. However,
if frequent shifting occurs while in DRIVE, use the
AutoStick shift control to manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions will improve performance
and extend transmission life by reducing excessive shifting
and heat build up. This action will also provide better
engine braking.
If you REGULARLY tow a trailer for more than 45 minutes
of continuous operation, then change the transmission
fluid and filter as specified for “police, taxi, fleet, or
frequent trailer towing”. Refer to the “Scheduled Servic-
ing” in “Servicing And Maintenance” for the proper main-
tenance intervals.
NOTE: Check the four-speed automatic transmission fluid
level before towing. The six-speed transmission does not
require a fluid level check before towing. If, however, you
notice fluid leakage or transmission malfunction, see your
authorized dealer immediately for assistance.

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, and E-85 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).
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 Cluster
Display” in “Getting To Know Your Instrument Panel” for
further information.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, brake
master cylinder, power steering, and transmission (4-
speed only) and fill as needed.
• Check function of all interior and exterior lights.

for diagnosing fluid leaks. Avoid using transmission seal-
ers as they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
Fluid Level Check — Four-Speed Automatic
Transmission
Use the following procedure to check the transmission
fluid level properly:
1. Park the vehicle on level ground.
2. Run the engine at normal idle speed for at least 60seconds, and leave the engine running for the rest of this
procedure.
3. Fully apply the parking brake, and press the brake pedal.
4. Place the gear selector momentarily into each gear position (allowing time for the transmission to fully
engage in each position), ending with the transmission
in PARK. 5. Wipe the area around the dipstick clean to prevent dirt
from entering the transmission.
6. Remove the dipstick and determine if the fluid is hot or cold. You can also read the transmission fluid tempera-
ture using the instrument cluster. Refer to Instrument
Cluster Display inGetting To Know Your Instrument
Panel for further information. Hot fluid is approxi-
mately 180°F (82°C), which is the normal operating
temperature after the vehicle is driven at least 15 miles
(24 km). Hot fluid cannot be held comfortably between
the fingertips. Cold fluid is at a temperature of approxi-
mately 80°F (27°C).
7. Wipe the dipstick clean and reinsert it until seated. Then, remove the dipstick 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.
• If the fluid is hot, the fluid level should be in the
crosshatched area marked “HOT” (between the upper
two holes in the dipstick).
• If the fluid is cold, the fluid level should be between
the lower two holes in the area marked “COLD”.
338 SERVICING AND MAINTENANCE
If the fluid level is low, add fluid through the dipstick tube
to bring it to the proper level. Do not overfill. After adding
any quantity of oil through the dipstick tube, wait at least
two minutes for the oil to fully drain into the transmission
before rechecking the fluid level.
NOTE:If it is necessary to check the transmission below
the operating temperature, the fluid level should be be-
tween the two COLD (lower) holes on the dipstick with the
fluid at approximately 80°F (27°C). If the fluid level is
correctly established at 80°F (27°C), it should be between
the HOT (upper) reference holes when the transmission
reaches 180°F (82°C). Remember it is best to check the level
at the normal operating temperature.
8. Check for leaks. Release the parking brake.
CAUTION!
• Using a transmission fluid other than the manufac-
turer ’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder, and will require more frequent fluid and
filter changes. Refer to “Fluids And Lubricants” in
“Technical Specifications” for fluid specifications.
(Continued)
CAUTION! (Continued)
•Dirt and water in the transmission can cause serious
damage. To prevent dirt and water from entering the
transmission after checking or replenishing fluid,
make sure that the dipstick cap is re-seated properly.
Fluid Level Check — Six-Speed Automatic
Transmission
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required, therefore the transmis-
sion filler tube is capped and no dipstick is provided. An
authorized dealer can check your transmission fluid level
using a special service dipstick. If you notice fluid leakage
or transmission malfunction, visit an authorized dealer
immediately to have the transmission fluid level checked.
Operating the vehicle with an improper fluid level can
cause severe transmission damage.

If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage may
occur. An authorized dealer has the proper tools to
adjust the fluid level accurately.
Fluid And Filter Changes
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
In addition, change the fluid and filter if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
