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 a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, select TOW/HAUL
mode or select a lower gear range (using the Electronic
Range Select [ERS] shift control).
NOTE:Using a lower gear range 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.
Tow/Haul Mode
To reduce the potential for automatic transmission over-
heating, activate the “TOW/HAUL” feature when driv-
ing in hilly areas, or select a lower gear range (using the
Electronic Range Select (ERS) shift control) on more
severe grades.
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.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:

Recreational Towing — Automatic Transmission
Recreational towing is allowed ONLY if the front wheels
are OFF the ground. This may be accomplished using a
tow dolly or vehicle trailer. If using a tow dolly, follow
this procedure:
1. Properly secure the dolly to the tow vehicle, followingthe dolly manufacturer’s instructions.
2. Drive the front wheels onto the tow dolly.
3. Firmly apply the parking brake. Place the transmis- sion in PARK.
4. Properly secure the front wheels to the dolly, following the dolly manufacturer’s instructions.
5. Release the parking brake.
CAUTION!
• DO NOT flat tow this vehicle. Damage to the
drivetrain will result. If this vehicle requires tow-
ing, make sure the drive wheels are OFF the
ground.
• Towing this vehicle in violation of the above re-
quirements can cause severe transmission damage.
Damage from improper towing is not covered un-
der the New Vehicle Limited Warranty.
284 STARTING AND OPERATING

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 in the instrument clus-
ter. This means that service is required for your vehicle.
Operating conditions such as frequent short-trips, trailer
tow, and extremely hot or cold ambient temperatures 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)” 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 4,000 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.
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
