WARNING: Exceeding any vehicle weight rating limitation
could result in serious damage to the vehicle and/or personal
injury.
Steps for determining the correct load limit:
1. Locate the statement ªThe combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs.º on your vehicle's placard.
2. Determine the combined weight of the driver and passengers that
will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and
luggage load capacity. For example, if the ªXXXº amount equals
1,400 lbs. and there will be five 150 lb. passengers in your vehicle,
the amount of available cargo and luggage load capacity is 650 lbs.
(1400-750 (5 x 150) = 650 lb.). In metric units (635-340 (5 x 68) =
295 kg.)
5. Determine the combined weight of luggage and cargo being loaded
on the vehicle. That weight may not safely exceed the available
cargo and luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle.
The following gives you a few examples on how to calculate the available
amount of cargo and luggage load capacity:
²Another example for your vehicle with 1400 lb. (635 kg) of cargo and
luggage capacity. You decide to go golfing. Is there enough load
capacity to carry you, 4 of your friends and all the golf bags? You and
four friends average 220 lb. (99 kg) each and the golf bags weigh
approximately 30 lb. (13.5 kg) each. The calculation would be: 1400 -
(5 x 220) - (5 x 30) = 1400 - 1100 - 150 = 150 lb. Yes, you have
enough load capacity in your vehicle to transport four friends and
your golf bags. In metric units, the calculation would be: 635 kg - (5 x
99 kg) - (5 x 13.5 kg) = 635 - 495 - 67.5 = 72.5 kg.
²A final example for your vehicle with 1400 lb. (635 kg) of cargo and
luggage capacity. You and one of your friends decide to pick up
cement from the local home improvement store to finish that patio

you have been planning for the past 2 years. Measuring the inside of
the vehicle with the rear seat folded down, you have room for 12-100
lb. (45 kg) bags of cement. Do you have enough load capacity to
transport the cement to your home? If you and your friend each weigh
220 lb. (99 kg), the calculation would be: 1400 - (2 x 220) - (12 x
100) = 1400 - 440 - 1200 = - 240 lb. No, you do not have enough
cargo capacity to carry that much weight. In metric units, the
calculation would be: 635 kg - (2 x 99 kg) - (12 x 45 kg) = 635 - 198 -
540 = -103 kg. You will need to reduce the load weight by at least 240
lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags, then the
load calculation would be:
1400 - (2 x 220) - (9 x 100) = 1400 - 440 - 900 = 60 lb. Now you have
the load capacity to transport the cement and your friend home. In
metric units, the calculation would be: 635 kg - (2 x 99 kg) - (9 x 45
kg) = 635 - 198 - 405 = 32 kg.
The above calculations also assume that the loads are positioned in your
vehicle in a manner that does not overload the Front or the Rear Gross
Axle Weight Rating specified for your vehicle on the Safety Compliance
Certification Label found on the edge of the driver's door.
Special loading instructions for owners of pickup trucks and
utility-type vehicles
WARNING: For important information regarding safe operation
of this type of vehicle, see thePreparing to drive your vehicle
section in theDrivingchapter of thisOwner's Guide.
WARNING: Loaded vehicles may handle differently than
unloaded vehicles. Extra precautions, such as slower speeds and
increased stopping distance, should be taken when driving a
heavily loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following charts.
Your vehicle's load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.

WARNING: Do not exceed the GVWR or the GAWR specified on
the certification label.
The certification label is found on the driver's door latch pillar.
WARNING: 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 vehicle control, vehicle rollover 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 authorized dealer or a
reliable trailer dealer if you require assistance.
Hitches
For towing trailers up to 2,000 lb. (907 kg), use a weight carrying hitch
and ball which uniformly distributes the trailer tongue loads through the
underbody structure. Use a frame-mounted weight distributing hitch for
trailers over 2,000 lb. (907 kg).

Do not install a single or multi-clamp type bumper hitch, or a hitch
which attaches to the axle. Underbody mounted hitches are acceptable if
they are installed properly. Follow the towing instructions of a reputable
rental agency.
Whenever a trailer hitch and hardware are removed, make sure all
mounting holes in the underbody are properly sealed to prevent noxious
gases or water from entering.
Safety chains
Always connect the trailer's safety chains to the frame or hook retainers
of the vehicle hitch. 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 trailer brakes are
safe if installed properly and adjusted to the manufacturer's
specifications. The trailer brakes must meet local and Federal
regulations.
WARNING: 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 all running
lights, brake lights, turn signals and hazard lights are working. See your
authorized dealer or trailer rental agency for proper instructions and
equipment for hooking up trailer lamps.
Using a step bumper
The optional step bumper is equipped with an integral hitch and requires
only a ball with a 3/4 inch (19 mm) shank diameter. The bumper has a
2,000 lb. (907 kg) trailer weight and 200 lb. (91 kg) tongue weight
capability.

The rated capacities (as shown in this guide) for trailer towing with the
factory bumper are only valid when the trailer hitch ball is installed
directly into the ball hole in the bumper. Addition of bracketry to either
lower the ball hitch position or extend the ball hitch rearward will
significantly increase the loads on the bumper and its attachments. This
can result in the failure of the bumper or the bumper attachments. Use
of any type of hitch extensions should be considered abuse.
Trailer tow connector
The trailer tow connector is located
under the rear bumper, on the
driver's side of the vehicle.

Driving while you tow
When towing a trailer:
²Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, and don't make full throttle
starts.
²Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations for towing a trailer.
²To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5±speed automatic transmissionsection in the
Drivingchapter.)
²Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gaugein theInstrument Cluster
chapter.
²Anticipate stops and brake gradually.
²Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
informationfor more information.
Trailer towing tips
²Practice turning, stopping and backing up 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±15% of the loaded trailer
weight.
²If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
