Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine/Transmission Frontal Area Max. GTW (Gross Trailer
Wt.)Max. Tongue Wt.
3.5L Automatic12 sq ft (1.11 sq m) 1,000 lbs (454 kg) 100 lbs (45 kg)
5.7L Automatic12 sq ft (1.11 sq m) 1,000 lbs (454 kg) 100 lbs (45 kg)
Refer to local laws for maximum trailer towing speeds
Trailer and Tongue Weight
Always load a trailer with 60% to 65% of the weight in
the front of the trailer. This places 10% to 15% of the
Gross Trailer Weight (GTW) on the tow hitch of your
vehicle. Loads balanced over the wheels or heavier in the
rear can cause the trailer to swayseverelyside to side
which will cause loss of control of the vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer accidents.
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.5
STARTING AND OPERATING 329

WARNING! (Continued)
Make certain that the load is secured in the trailer
and it will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance, or damage to
brakes, axle, engine, transmission, steering, suspen-
sion, chassis structure, or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
PARK. Always, block orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. Max loading as defined on the “Tire and Loading
Information” placard.
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight.)

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 this range, use
the Electronic Range Select (ERS) or Autostickmode (if
equipped) to select a lower gear range.
NOTE:Using a lower gear range while operating the
vehicle under heavy operating conditions will improve
performance and extend transmission life by reducing
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 intervalspecified for “police, taxi, fleet, or frequent trailer tow-
ing” in the Maintenance Schedule. Refer to Section 8 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.
Autostick/Electronic Range Select (ERS)

By using the Electronic Range Select (ERS) or
Autostickmode and selecting a specific gear range,
frequent shifting can be avoided. The highest gear
range should be selected that allows for adequate
5

performance. For example, choose “4” if the desired
speed can be maintained. Choose “3” or “2” if needed
to maintain the desired speed.
Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear range or vehicle
speed when road conditions and RPM level allows.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods, put transmission in
NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Recreational towing is allowed ONLY if the driveshaft
is removed.Towing with the rear wheels on the ground
while the driveshaft is connected can result in severe
transmission damage.
336 STARTING AND OPERATING

HAZARD WARNING FLASHER
The Hazard Warning flasher switch is located in the
switch bank near the bottom center of the instrument
panel.
Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flasher.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.When you must leave the vehicle to seek assistance, the
Hazard Warning flasher will continue to operate even
though the ignition switch is in the LOCK position.
NOTE:With extended use, the Hazard Warning flasher
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — slow down.
•In city traffic — while stopped, put transmission in
NEUTRAL, but do not increase engine idle speed.

JUMP-STARTING
WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is ON. You can be hurt by the fan.
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned
fuel could enter the catalytic converter and once
the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged battery, booster cables may be used to
obtain a start from another vehicle. This type of
start can be dangerous if done improperly, so
follow this procedure carefully.
