DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine's air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs.
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transmission is submerged
may allow water into the transmission and cause internal
transmission damage.
VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
²Base Curb Weight: Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include passengers or
aftermarket equipment.
²Payload: Combined maximum allowable weight of cargo, passengers
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
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.

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).
Driving
122
Page 123 of 216

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
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.
Towing a trailer places an additional load on your vehicle's engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully after any towing operation.

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.
Hitches
For towing trailers up to 907 kg (2 000 lb), use a weight carrying hitch
and ball which uniformly distributes the trailer tongue loads through the
underbody structure. Use a frame-mounted weight distrubuting hitch for
trailers over 907 kg (2 000 lb).
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 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.
