between forward and reverse
gears. DO NOT rock the vehicle for
more than a few minutes. The
transmission and tires may be
damaged or the engine can
overheat.
Do not spin the wheels at
over 55 km/h (35 mph).
The tires may fail and injure a
passenger or bystander.
VEHICLE LOADING
It is extremely dangerous
to ride in a cargo area,
inside or outside of a vehicle. In
a collision, people riding in these
areas are more likely to be
seriously injured or killed.
Do not allow people to
ride in any area of your
vehicle that is not equipped with
seats and safety belts.
Be sure everyone in your
vehicle is in a seat and
using a safety belt properly.
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.
Driving
107

²Maximum Trailer Weight Rating:
Maximum weight of a trailer the
vehicle is permitted to tow. The
maximum trailer weight rating
equals 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 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.
If the GVWR or the GAWR
specified on the Safety
Compliance Certification Label is
exceeded, your vehicle may be
damaged or you may lose control
and injure someone.
To obtain correct weights, try
taking your vehicle to a shipping
company or an inspection station
for trucks.
Driving
109

Do not use replacement tires with
lower weight capacities than the
original because they may lower
the vehicle's GVWR and GAWR
limitations. Replacement tires with
a higher weight limit than the
originals do not increase the
GVWR and GAWR limitations.
TRAILER TOWING
Your vehicle may tow a Class I or
II trailer provided the maximum
trailer weight is less than or equal
to the maximum trailer weight
listed for your engine and rear axle
ratio. See theTrailer towing table
later in this chapter.
Do not exceed the maximum loads
stated on the Safety Compliance
Certification Label. Refer to
Vehicle loadingfor a definition of
the terms on the label.
Your vehicle's load capacity is
designated by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle.
Distribute the trailer load so that
only 10 to 15% of the total weight
of the trailer is on the tongue. Tie
down the load so that it does not
shift and change the weight on the
hitch.
Towing a trailer places an
additional load on your vehicle's
engine, transmission, axle, brakes,
tires and suspension. Inspect these
components carefully before and
after any towing operation.
Driving

If the GVWR or the GAWR
specified on the Safety
Compliance Certification Label is
exceeded, your vehicle may be
damaged or you may lose control
and injure someone.
Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limits of the vehicle and could
result in engine damage,
transmission/axle damage,
structural damage, loss of
control, and personal injury.
Calculating the load your
vehicle can carry/tow
1. Use the Safety Compliance
Certification Label to find the axle
code number and engine type for
your vehicle.
2. Use the appropriate maximum
Gross Combined Weight Rating
(GCWR) chart to find the
maximum GCWR for your type
engine and rear axle ratio.
3. 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.
4. 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

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
Do not use or install hitches that
clamp onto the bumper or to the
axle. Underbody hitches are
acceptable if installed properly.
The rear bumper has an integral
hitch and only requires a ball with
a 3/4 inch shank diameter. The

Servicing while towing
If you tow a trailer for long
distances, your vehicle will require
more frequent service intervals.
Refer to theService Guidefor
more information.
Trailer towing
²Practice turning, stopping and
backing in an area before
starting on a trip to get the feel
of the vehicle/trailer
combination. When turning,
drive slightly beyond the normal
turning point so the trailer
wheels will clear curbs and
other obstacles.
²Allow more room for stopping
with a trailer attached.
²The trailer tongue weight should
be 10-15% of the loaded trailer
weight for a Class I or II rear
bumper hitch.
²After you have travelled about
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)
to 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.

immediately.
To avoid damage or injury,
follow these directions in
the order they are given. If in
doubt, call for road service.
Before jump starting a vehicle:
²Make sure the booster battery
vehicle has a 12-volt starting
system (a 24-volt power supply
will cause vehicle damage).
²Park the vehicles close to each
other, but do not allow the
vehicles to touch each other.
²Check to make sure neither
battery is disconnected.
²Remove any excessive corrosion
from the battery terminals.
²Turn on the heater fan in each
vehicle to prevent damage from
voltage surges.
To jump start the vehicle, connect
the jumper cables in the following
order:
1. Disabled battery positive
terminal.
2. Booster battery positive
terminal.
3. Booster battery negative
terminal.
4. Disabled vehicle engine.

Do not connect the end of
the second cable to the
negative (-) terminal of the
battery to be jumped. A spark
may cause an explosion of the
gases that surround the battery.
5. Start the engine in the vehicle
with the booster battery.
6. Wait a few minutes and start the
engine in the vehicle with the
disabled battery.
7. After a few minutes, the
disabled battery should be
recharged. Disconnect the jumper
cables in reverse order.
Let the vehicle idle for a few
minutes to allow the engine to
relearn the proper idle conditions.
Avoid using unnecessary electrical
accessories for a short while to let
the battery fully recharge. A
battery charger may need to be
used to fully recharge the battery.
