Towing Requirements – Tires
•Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
•
Check the trailer tires for proper tire inflation pressures
before trailer usage.
•Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires – General Information”
in “Starting and Operating” for the proper inspection
procedure.
• When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for the proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements – Trailer Brakes
• Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).
390 STARTING AND OPERATING
Page 393 of 519

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have a
collision.
(Continued)
WARNING! (Continued)
•Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in a
collision.
Towing Requirements – Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four-pin and
seven-pin wiring harness. Use a factory approved trailer
harness and connector.
NOTE: Do not cut or splice wiring into the vehicle’s
wiring harness.5

The electrical connections are all complete to the vehicle,
but you must mate the harness to a trailer connector.

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. 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.

Recreational Towing – All Models
Recreational towing is allowedONLYif 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, following the 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.

STARTING AND OPERATING 395

NOTE:There are steps that you can take to slow down
an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control
to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator.
If you see or hear steam coming from under the hood,
(Continued)
WARNING! (Continued)
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
Engine Oil Overheating (2.4L Engine Only) —
If Equipped
During sustained high-speed driving or trailer tow up
long grades on a hot day, the engine oil temperature may
become too hot. If this happens, the “HOTOIL” message
flashes in the odometer and the vehicle speed will be
reduced to 53 mph (85 km/h) until the engine oil
temperature is reduced.
NOTE:The vehicle speed is reduced to a maximum of
53 mph (85 km/h). You may of course, reduce your
vehicle speed further if needed.

MAINTAINING YOUR VEHICLE 463
Page 480 of 519

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 than
your 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
