This section describes procedures for towing a disabled
vehicle using a commercial towing service. If the trans-
mission and drivetrain are operable, disabled vehicles
may also be towed as described under “Recreational
Towing” in the “Starting And Operating” section.
NOTE:Vehicles equipped with air suspension must be
placed in Transport mode, before tying them down (from
the body) on a trailer or flatbed truck. Refer toAir
SuspensioninStarting And Operatingfor more infor-
mation. If the vehicle cannot be placed in Transport mode
(for example, engine will not run), tie-downs must be
fastened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.

If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the key fob is unavailable or the vehicle’s battery is
discharged, refer to ”Manual Park Release” or “Shift
Lever Override” in this section for instructions on shift-
ing the automatic transmission out of PARK for towing.
CAUTION!
•Do not use sling type equipment when towing.
Vehicle damage may occur.
•When securing the vehicle to a flat bed truck, do
not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheelsOFFthe ground using a flatbed.
If flatbed equipment is not available, and the transmis-
sion is operable, this vehicle may be towed (with rear
wheels on the ground) under the following conditions:
•The transmission must be in NEUTRAL.
•The towing speed must not exceed 30 mph (48 km/h).
•The towing distance must not exceed 15 miles (24 km)
for 6-speed transmission, or 30 miles (48 km) for
8-speed transmission.
If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than 15
miles (24 km) for 6-speed transmission, or 30 miles
(48 km) for 8-speed transmission, tow with the rear
wheelsOFFthe ground. Acceptable methods are to tow
the vehicle on a flatbed, or with the front wheels raised

and the rear wheels on a towing dolly, or (when using a
suitable steering wheel stabilizer to hold the front wheels
in the straight position) with the rear wheels raised and
the front wheels on the ground.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe engine and/or transmission
damage. Damage from improper towing is not cov-
ered under the New Vehicle Limited Warranty.
Four-Wheel Drive Models
The manufacturer recommends towing with all wheels
OFFthe ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of vehicle raised and
the opposite end on a towing dolly.
If flatbed equipment is not available, and the transfer
case is operable, the vehicle may be towed (in theforward direction, withALLwheels on the ground),IF
the transfer case is in NEUTRAL (N) and the transmis-
sion is inPARK(for automatic transmissions) or in gear
(NOT in NEUTRAL, for manual transmissions). Refer to
“Recreational Towing” in “Starting And Operating” for
further information and detailed instructions.
CAUTION!
•Front or rear wheel lifts must not be used. Internal
damage to the transmission or transfer case will
occur if a front or rear wheel lift is used when

Conditions that would require replacement:
•Rib chunking (one or more ribs has separated from belt
body)
•Rib or belt wear
•Longitudinal belt cracking (cracks between two ribs)
•Belt slips
•“Groove jumping(belt does not maintain correct
position on pulley)
•Belt broken (note: identify and correct problem before
new belt is installed)
•Noise (objectionable squeal, squeak, or rumble is
heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty component
such as a belt pulley. Belt pulleys should be carefully
inspected for damage and proper alignment.Belt replacement on some models requires the use of
special tools, we recommend having your vehicle ser-
viced at an authorized dealer.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required.

burn or even blind you. Do not allow battery fluid
to contact your eyes, skin, or clothing. Do not lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water. Refer to
“Jump-Starting Procedures” in “What To Do In

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 otherthan your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)” or “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information.
1500 Models Only
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.
2500 – 3500 Models Only
NOTE:Under no circumstances should oil change inter-
vals exceed 8,000 miles (13,000 km), twelve months or 350
