TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery
surfaces, particularly when one wheel is on a poor
traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle.
Extended use of other than the manufacturer's
specified size tires on a Traction-Lok rear axle could
result in a permanent reduction in effectiveness.
This loss of effectiveness does not affect normal
driving and should not be noticeable to the driver.
To avoid injury, never run the engine with
one wheel off the ground, such as when
changing a tire.

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.
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.
Driving
106

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 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.
Driving
107

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.
TRAILER TOWING
Your vehicle is capable of towing a trailer up to
454 kg (1 000 lbs.) gross trailer weight with a
maximum tongue load of 45 kg (100 lbs.). Do not
tow a trailer until your vehicle has been driven at
least 800 km (500 miles).
Towing a trailer places an additional load on your
vehicle's engine, transmission, axles, brakes, tires
and suspension. Inspect these components carefully
after towing.
Do not exceed the GVWR or the GAWR
specified on the certification label.
Towing trailers beyond the maximum
recommended gross trailer weight could result
in engine damage, transmission/axle 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.
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.
Driving
108

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.
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.
Driving
109

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.
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 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.

HAZARD FLASHER
Use only in an emergency to warn traffic of vehicle
breakdown, approaching danger, etc. The hazard
flashers can be operated when the ignition is off.
²The hazard lights
control is located on
top of the steering
column.
²Depress hazard
lights control to
activate all hazard
flashers
simultaneously.
²Depress control again to turn the flashers off.
RESETTING THE FUEL PUMP SHUT-OFF
SWITCH
After a collision, if the engine cranks but does not
start, the fuel pump shut-off switch may have been
activated. The shut-off switch is a device intended to
stop the electric fuel pump when your vehicle has
been involved in a substantial jolt.
The fuel pump shut-off
switch is located on
the left side of the
trunk behind the trunk
liner.
