Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing the trailer in an area located away from
heavy traffic.
Automatic Transmission
The “DRIVE” range can be selected when towing. How-
ever, if frequent shifting occurs while in this range,
activate the TOW/HAUL feature. Refer to “Automatic
Transmission” in “Starting and Operating” for further
information.
NOTE:Using the TOW/HAUL feature while operating
the vehicle under heavy operating conditions will im-
prove performance and extend transmission life by re-
ducing excessive shifting and heat build up. 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 automatic
transmission fluid and filter according to the interval specified for “police, taxi, fleet, or frequent trailer tow-
ing.” Refer to “Maintenance Schedule” for the proper
maintenance intervals.
TOW/HAUL
To reduce potential for automatic transmission overheat-
ing, press the TOW/HAUL button when driving in hilly
areas or select the
2range on more severe grades. Refer
to “Automatic Transmission” in “Starting and Operat-
ing” for further information.
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.

Recreational Towing — Two-Wheel Drive Models
Recreational towing is allowed ONLY if the rear wheels
areOFF 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, following
the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly set the parking brake. Place the transmission in
PARK.
4. Properly secure the rear wheels to the dolly, following
the dolly manufacturer’s instructions.
5. Remove the ignition key.
6. Install a suitable clamping device, designed for tow-
ing, to secure the front wheels in the straight position. Flat towing (with all four wheels on the ground) is
allowed ONLY if the driveshaft is removed.
Towing
with the rear wheels on the ground while the driveshaft
is connected will result in severe transmission damage.
WARNING!
If the driveshaft is removed, the vehicle can roll even
if the transmission is in PARK, which could cause
serious injury or death.
The parking brake mustbe firmly engaged and the
wheels chocked during driveshaft removal and installa-
tion. The parking brake must remainengaged unless the
vehicle is securely and properly connected to the tow
vehicle, or the driveshaft is completely reinstalled. See
your authorized dealer for proper driveshaft removal
and reinstallation procedures, including flange
orientation/alignment, use of thread-locking compound,
proper bolt torque specifications, etc.

MAINTENANCE SCHEDULE
The Scheduled Maintenance services listed in this
manual must be done at the times or mileages specified
to protect your vehicle warranty and ensure the best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving. Inspection and service should also be done
anytime a malfunction is suspected.
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.
On Electronic Vehicle Information Center (EVIC)
equipped vehicles, “Oil Change Required” will be dis-
played in the EVIC and a single chime will sound,
indicating that an oil change is necessary.On Non-EVIC equipped vehicles, “Change Oil” will flash
in the instrument cluster odometer and a single chime
will sound, indicating that an oil change is necessary.
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 “Change Oil” message is displayed.
Depending on operating conditions, the message may
appear as early as 3,500 miles (5 630 km) since last reset.
Have your vehicle serviced as soon as possible, within
the next 500 miles (805 km).
