Automatic Transmission
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in DRIVE, select the
3range (with four-speed transmission), or select a lower
gear using the AutoStick® shift control (with six-speed
transmission).
NOTE: Using a lower gear while operating the vehicle
under heavy loading conditions, will improve perfor-
mance and extend transmission life by reducing exces-
sive 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 auto-
matic transmission fluid and filter as specified for “po-
lice, taxi, fleet, or frequent trailer towing.” Refer to the
“Maintenance Schedule” for the proper maintenance
intervals. NOTE:
Check the transmission fluid level (four-speed
transmission only) before towing. The six-speed trans-
mission does not require a fluid level check before
towing. If, however, you notice fluid leakage or transmis-
sion malfunction, see your authorized dealer immedi-
ately for assistance.
AutoStick®
– When using the AutoStick® shift control, select the highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “4” if
the desired speed can be maintained. Choose “3” or
“2” if needed to maintain the desired speed.
– To prevent excess heat generation, avoid continuous driving at high RPM. Reduce vehicle speed as neces-
sary to avoid extended driving at high RPM. Return to
a higher gear or vehicle speed when grade and road
conditions allow.

STARTING AND OPERATING 393
CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
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. Do not check oil level
before starting the engine after it has sat overnight.
Checking engine oil level when the engine is cold will
give you an incorrect reading.
Checking the oil while the vehicle is on level ground and
only when the engine is hot, will improve the accuracy of
the oil level readings. Maintain the oil level between the
range markings on the dipstick. Either the range mark-
ings consist of a crosshatch zone marked SAFE or a
crosshatch zone marked with MIN at the low end of the
range and MAX at the high end of the range. Adding one
quart of oil when the reading is at the low end of the
range marking will raise the oil level to the high end of
the range marking.

MAINTAINING YOUR VEHICLE 429
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes for diagnosing fluid
leaks. Avoid using transmission sealers 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 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 60
seconds, 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 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.
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. Hot fluid is approximately 180° F (82° C),
which is the normal operating temperature after the
vehicle is driven at least 15 miles (24 km). Hot fluid

MAINTAINING YOUR VEHICLE 451
cannot be held comfortably between the fingertips.
Cold fluid is at a temperature of approximately 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 up-
per 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.”
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.
8. Check for leaks. Release the parking brake.
To prevent dirt and water from entering the transmission
after checking or replenishing fluid, make sure that the
dipstick cap is properly reseated.
CAUTION!
•
Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality and/or torque con-
verter shudder, and will require more frequent
fluid and filter changes. Refer to “Fluids, Lubri-
cants, and Genuine Parts” in this section for fluid
specifications.

452 MAINTAINING YOUR VEHICLE
CAUTION!(Continued)
•Dirt and water in the transmission can cause seri-
ous damage. To prevent dirt and water from enter-
ing the transmission after checking or replenishing
fluid, make sure that the dipstick cap is re-seated
properly.
Fluid Level Check – Six-Speed 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
transmission filler tube is capped and no dipstick is
provided. Your authorized dealer can check your trans-
mission fluid level using a special service dipstick. If you
notice fluid leakage or transmission malfunction, visit
your authorized dealer immediately to have the trans-
mission fluid level checked. Operating the vehicle with an improper fluid level can cause severe transmission
damage.
CAUTION!
•
If a transmission fluid leak occurs, visit your au-
thorized dealer immediately. Severe transmission
damage may occur. Your authorized dealer has the
proper tools to adjust the fluid level accurately.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
In addition, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the trans-
mission is disassembled for any reason.

MAINTAINING YOUR VEHICLE 453
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 ser-
vice 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 “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 thanyour authorized dealer, the message can be reset by refer-
ring to the steps described under “Electronic Vehicle Infor-
mation Center (EVIC)/Oil Change Required” in “Under-
standing 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.
Once A Month Or Before A Long Trip:
• 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 reservoir, brake
master cylinder, power steering and transmission
(four-speed only) and fill as needed
• Check function of all interior and exterior lights
