Consider the following items when computing the
weight on the rear axle:
•the tongue weight of the trailer
•the weight of any other type of cargo or equipment put
in or on your vehicle
NOTE:Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options, or dealer-installed options,
must be considered as part of the total load on your
vehicle. Refer to the Certification label located at the
driver’s door for the Gross Vehicle Weight Rating.
WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Perform the maintenance listed in the “Maintenance
Schedules” section of this manual (Section 8). When
towing a trailer, never exceed the Gross Axle Weight
Rating (GAWR), or Gross Combined Vehicle Weight
(GCVW).
CAUTION!
When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or damage
to brakes, axle, engine, transmission, steering, sus-
pension, body structure or tires.

Trailer Towing Mirrors — If Equipped
These mirrors are designed with an adjustable mirror
head to provide a greater vision range when towing
extra-wide loads. To change position inboard or out-
board, the mirror head should be rotated (flipped Out or
In). A small blindspot mirror is integrated onto the main
mirror surface.
Cooling System Tips — Trailer Towing
To reduce potential for engine and transmission over-
heating, take the following actions:
•City Driving—when stopped, put the transmission in
N (Neutral) and increase the engine idle speed.
•Highway Driving—reduce your speed.

•Air Conditioning—turn it off temporarily.
•Hilly Terrain—Turn overdrive off.
See Cooling System Operating information in the Service
and Maintenance section of this manual for more infor-
mation.
Automatic Transmission Oil Temperature Warning
Light
All vehicles with automatic transmissions are equipped
with a transmission sump oil temperature sensor and
warning light. If elevated transmission temperatures are
encountered, the engine controller will select the most
desirable gear until the transmission temperatures are
reduced. If transmission oil temperatures continue to
rise, a warning light located in the instrument cluster will
illuminate. If this should occur, stop the vehicle, shift to
Neutral, and run the engine at idle or faster until the light
goes off.
Towing With An Automatic Transmission
Vehicles equipped with an automatic transmission may
shift into and out of Overdrive, or a lower gear, when
driving in hilly areas, when heavily loaded, or when
towing into heavy winds.
When this condition occurs, select TOW/HAUL mode or
shift into a lower gear to prevent excessive transmission
wear and/or overheating, and to provide better engine
braking.
NOTE:Do not exceed the following RPM while manu-
ally downshifting:
•5800 rpm with 3.7L engines.
•5800 rpm with 4.7L engines.
•5600 rpm with 5.7L engines.
If your vehicle has an automatic transmission and you
tow a trailer frequently, change transmission fluid and
filter(s) according to Maintenance Schedule “B.”

5. Cargo capacity will be reduced by the addition of
options or passengers, etc.
The loaded vehicle weight, including the snowplow
system, all aftermarket accessories, driver, passengers,
options, and cargo, must not exceed either the Gross
Vehicle Weight (GVWR) or Gross Axle Weight (GAWR)
ratings. These weights are specified on the Safety Com-
pliance Certification Label on the driver’s side door
opening.
NOTE: Detach the snowplow when transporting
passengers.
Vehicle front end wheel alignment was set to specifica-
tions at the factory without consideration for the weight
of the plow. Front end tow-in should be checked and
reset if necessary at the beginning and end of the
snowplow season. This will help prevent uneven tire
wear.The blade should be lowered whenever the vehicle is
parked.
Maintain and operate your vehicle and snowplow equip-
ment following the recommendations provided by the
specific snowplow manufacturer.
Over the Road Operation With Snowplow
Attached
The blade restricts air flow to the radiator and causes the
engine to operate at higher than normal temperatures.
Therefore, when transporting the plow, angle the blade
completely and position it as low as road or surface
conditions permit. Do not exceed 40 mph (64 km/h). The
operator should always maintain a safe stopping distance
and allow adequate passing clearance.

Keep all snowplow electrical connections and battery
terminals clean and free of corrosion.
When plowing snow, to avoid transmission and driv-
etrain damage, the following precautions should be ob-
served.
•Operate with transfer case in 4L when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4H.
•Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission between forward and reverse.
NOTE:Change the automatic transmission fluid and
filter(s) according to Maintenance ScheduleB.
RECREATIONAL TOWING — 4 WHEEL DRIVE
VEHICLES (BEHIND MOTORHOME, ETC.)
Recreational Towing – 2 Wheel Drive Models
Recreational towing 2 Wheel Drive is not allowed.
Towing with the rear wheels on the ground can result in
severe transmission damage.
CAUTION!
Failure to follow these requirements can cause se-
vere damage to the transmission and/or transfer case.

CAUTION!
Internal damage to the transfer case will occur if a
front or rear wheel lift is used when recreational
towing.
NOTE:Both the Manual Shift and Electronic Shift
transfer cases must be shifted into Neutral (N) for
recreational towing. Automatic transmissions must be
placed in P (Park) position for recreational towing.
Manual transmissions must be left in gear (not in neutral)
for recreational towing. Refer below for the proper trans-
fer case Neutral shifting procedure for your vehicle.
Recreational Towing Procedure — Manual Shift
Transfer Case — If Equipped
Use the following procedure to prepare your vehicle for
recreational towing:
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in N (NEUTRAL) before
recreational towing to prevent damage to internal
parts.
1. Bring the vehicle to a complete stop.
2. Shut OFF the engine.
3. Depress the brake pedal.
4. Shift automatic transmission to N (NEUTRAL), or
