²GVW (Gross Vehicle Weight): Base curb weight plus payload
weight. The GVW is not a limit or a specification.
²GVWR (Gross Vehicle Weight Rating): Maximum total weight of
the base vehicle, passengers, optional equipment and cargo. The
GVWR is specific to each vehicle and is listed on the Safety
Compliance Label on the driver's door pillar.
²GAWR (Gross Axle Weight Rating): Carrying capacity for each
axle system. The GAWR is specific to each vehicle and is listed on the
Safety Compliance Label on the driver's door pillar.
²GCW (Gross Combined Weight): The combined weight of the
towing vehicle (including passengers and cargo) and the trailer.
²GCWR (Gross Combined Weight Rating): Maximum combined
weight of towing vehicle (including passengers and cargo) and the
trailer. The GCWR indicates the maximum loaded weight that the
vehicle is designed to tow.
²Maximum Trailer Weight Rating: Maximum weight of a trailer the
vehicle is permitted to tow. The maximum trailer weight rating is
determined by subtracting the vehicle curb weight for each
engine/transmission combination, any required option weight for trailer
towing and the weight of the driver from the GCWR for the towing
vehicle.
²Maximum Trailer Weight: maximum weight of a trailer the loaded
vehicle (including passengers and cargo) is permitted to tow. It is
determined by subtracting the weight of the loaded trailer towing
vehicle from the GCWR for the towing vehicle.
²Trailer Weight Range: Specified weight range that the trailer must
fall within that ranges from zero to the maximum trailer weight rating.
Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
Do not exceed the GVWR or the GAWR specified on the Safety
Compliance Certification Label.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle's GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.

The Certification Label, found on the inside pillar of the driver's door,
lists several important vehicle weight rating limitations. Before adding
any additional equipment, refer to these limitations. If you are adding
weight to the front of your vehicle, (potentially including weight added
to the cab), the weight added should not exceed the Front Axle Reserve
Capacity (FARC). Additional frontal weight may be added to the front
axle reserve capacity provided you limit your payload in other ways (i.e.
restrict the number of passengers or amount of cargo carried).
You may add equipment throughout your vehicle if the total weight
added is equal to or less than the Total Axle Reserve Capacity (TARC)
weight. You should NEVER exceed the Total Axle Reserve Capacity.
Always ensure that the weight of passengers, cargo and equipment being
carried is within the weight limitations that have been established for
your vehicle including both Gross Vehicle Weight and Front and Rear
Gross Axle Weight Rating limits. Under no circumstance should these
limitations be exceeded. Exceeding any vehicle weight rating limitation
could result in serious damage to the vehicle and/or personal injury.
Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum gross combined weight rating (GCWR)
chart to find the maximum GCWR for your type engine and rear axle
ratio.
2. Weigh your vehicle as you customarily operate the vehicle without
cargo. To obtain correct weights, try taking your vehicle to a shipping
company or an inspection station for trucks.
3. Subtract your loaded vehicle weight from the maximum GCWR on the
following charts. This is the maximum trailer weight your vehicle can tow
and must fall below the maximum shown under maximum trailer weight
on the chart.

TRAILER TOWING
Trailer towing with your vehicle may
require the use of a trailer tow
option package.
Trailer towing puts additional loads
on your vehicle's engine,
transmission, axle, brakes, tires, and
suspension. For your safety and to
maximize vehicle performance, be
sure to use the proper equipment
while towing.
Follow these guidelines to ensure safe towing procedure:
²Stay within your vehicle's load limits. If exceeded, cargo should be
removed from the trailer and/or the vehicle until all weights are within
specified limits.
²Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
²Use extra caution when driving while trailer towing. Refer toDriving
while you towin this chapter.
²Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the ªService Guideº.
²Do not tow a trailer until your vehicle has been driven at least 800 km
(500 miles).
²Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
If your vehicle is equipped with the optional heavy duty trailer tow
wiring, it is pre-wired for trailer towing. An electrical connector is
provided under the instrument panel for installing a customer-supplied
electric brake controller. Another electrical connector is provided at the
hitch. This connector provides power to the trailer for taillamps, stop
and turn lamps, back up lamps, battery charge, electric brakes (when a
customer provided controller is installed) and ground. The kit included
with your vehicle provides you with adaptors to attach the brake
controller and convert the hitch connector for Class I trailer usage.

Maximum frontal area of trailer is 5.6 square meters (60 square feet)
Do not exceed the maximum loads listed on the Safety Compliance
Certification label. For load specification terms found on the label, refer
toVehicle loadingin this chapter. Remember to figure in the tongue
load of your loaded trailer when figuring the total weight.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of control
and personal injury.

Preparing to tow
Use the proper equipment for towing a trailer, and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
If your vehicle is not equipped with the factory heavy duty trailer tow
option, auxiliary coolers are recommended for the automatic
transmission system if you are planning on:
²traveling farther than 80 km (50 miles)
²towing in hilly terrain
²towing frequently
Hitches
Do not use hitches that clamp onto the vehicle's bumper or attach to the
axle. You must distribute the load in your trailer so that 10% of the total
weight of the trailer is on the tongue.
Load equalizing hitch
When hooking up a trailer using a load equalizing hitch, always use the
following procedure:
1. Park the unloaded vehicle on a level surface. With the ignition on and
all doors closed, allow the vehicle to stand for several minutes so that it
can level.
2. Turn the air suspension (if equipped) control to OFF.
3. Measure the height of a reference point on the front and rear bumpers
at the center of the vehicle.
4. Attach the trailer to the vehicle and adjust the hitch equalizers so that
the front bumper height is within 0±13 mm (0.5 in) of the reference
point. After proper adjustment, the rear bumper should be no higher
than in Step 3.
5. Turn the air suspension (if equipped) control to ON.
Adjusting an equalizing hitch so the rear bumper of the vehicle
is lower or higher than it was unloaded will defeat the function
of the load equalizing hitch and may cause unpredictable handling.

Safety chains
Always connect the trailer's safety chains to the vehicle. To connect the
trailer's safety chains, cross the chains under the trailer tongue and allow
slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type brakes are safe if
installed properly and adjusted to the manufacturer's specifications. The
trailer brakes must meet local and Federal regulations.
Do not connect a trailer's hydraulic brake system directly to your
vehicle's brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure your
trailer lamps conform to local and Federal regulations. See your dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.
Using a step bumper
The rear bumper is equipped with an integral hitch and requires only a
ball with a 25.4 mm (one inch) shank diameter. The bumper has a
1 814 kg (4 000 lb.) trailer weight and 181 kg (400 lb.) tongue weight
capability.
Use a frame-mounted weight distributing hitch for trailers over 1814 kg
(4 000 lb).
Driving

Driving while you tow
Do not drive faster than 88 km/h (55 mph) when towing a trailer.
Speed control may shut off if you are towing on long, steep grades.
When towing a trailer:
²Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
²Anticipate stops and brake gradually.
Exceeding the GCWR rating may cause internal transmission
damage and void your warranty coverage.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your Scheduled Maintenance guide
for more information.
Towing behind another vehicle
Do not tow your vehicle behind another vehicle, such as an RV.
Your vehicle cannot be flat-towed with all wheels on the ground.
Trailer towing tips
²Practice turning, stopping and backing up in an area before starting on
a trip to get the feel of the vehicle trailer combination. When turning,
make wider turns so the trailer wheels will clear curbs and other
obstacles.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be 10% of the loaded trailer weight.
²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) and increase idle speed. This aids engine
cooling and air conditioner efficiency.
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.
Driving

Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
²Do not allow the static water level to rise above the bottom edge of
the rear bumper and
²Do not allow waves to break higher than 15 cm (six inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions, reliability and
causing internal transmission damage.
Replace the rear axle lubricant anytime the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
Disconnect the wiring to the trailer before backing the trailer into the
water. Reconnect the wiring to the trailer after the trailer is removed
from the water.
LUGGAGE RACK (IF EQUIPPED)
The rear crossbar can be adjusted to fit the item being carried. The front
crossbar does not move.
To adjust the luggage rack, push the
adjustment lever forward (toward
the front of the vehicle), then slide
the crossbar forward and lock the
adjusting levers by pushing them
down (toward the back of the
vehicle). Pull the crossbar rearward
to ensure that it is locked in place.
Load luggage at the front crossbar and adjust the rear crossbar as
necessary.
²Do not exceed 90.7 kg (200 lb) of luggage if the weight is placed
directly on the crossbars.
²Do not exceed 68 kg (150 lb) if the weight is resting directly on the
roof.
Use adjustable tie down loops to secure the load.
