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. The
transmission controls include an adaptive drive strategy
to avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you can use
the AutoStick® shift control (if equipped) or the LOW
range (if equipped) to select a lower gear.
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 buildup. This action will also
provide better engine braking. If you REGULARLY tow a trailer for more than 45 min-
utes of continuous operation, then change the transmis-
sion fluid and filter as specified for “police, taxi, fleet, or
frequent trailer towing.” Refer to the “Maintenance
Schedule” for the proper maintenance intervals.Electronic Speed Control – If Equipped
•
Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.

Fluid And Filter Changes
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
In addition, change the fluid and filter if the transmission
is disassembled for any reason.
All Wheel Drive (AWD) – If Equipped
The all wheel drive system consists of a transfer case and
front differential. The exterior surface of these compo-
nents should be inspected for evidence of fluid leaks.
Confirmed leaks should be repaired as soon as possible.
The transfer case fluid fill/inspection plug is located in
the middle of the rear housing. To inspect the transfer
case fluid level, remove the fill/inspection plug. The
fluid level should be even with the bottom of the hole.
Use this plug to add fluid as required.
The front differential fill plug is located on the outer cover
near the halfshaft attachment. To inspect the differential
fluid level, remove the fill plug. The fluid level should be
even with or slightly below the bottom of the hole.
Fluid Changes
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Rear Axle
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected.
If gear oil leakage is suspected inspect the fluid level. Refer
to “Fluids, Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” 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 as
needed
• Check function of all interior and exterior lights
Required Maintenance Intervals.
Refer to the maintenance schedules on the following
page for the required maintenance intervals.At Every Oil Change Interval As Indicated By Oil Change Indicator System:
•Change oil and filter
• Rotate the tires. Rotate at the first sign of
irregular wear, even if it occurs before the
oil indicator system turns on.
• Inspect battery and clean and tighten terminals as
required
• Inspect automatic transmission fluid if equipped
with dipstick
• Inspect brake pads, shoes, rotors, drums, hoses
and park brake
• Inspect engine cooling system protection and
hoses
• Inspect exhaust system
• Inspect engine air cleaner if using in dusty or
off-road conditions
