TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer, carefully
review this information to tow your load as efficiently
and safely as possible.
To maintain the New Vehicle Limited Warranty cover-
age, follow the requirements and recommendations in
this manual concerning vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will
assist you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo, and
tongue weight. The total load must be limited so that
you do not exceed the GVWR.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of
all cargo, consumables and equipment (permanent or
temporary) loaded in or on the trailer in its "loaded and
ready for operation" condition. The recommended way
to measure GTW is to put your fully loaded trailer on
a vehicle scale. The entire weight of the trailer must be
supported by the scale.Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your
vehicle and trailer when weighed in combination.
NOTE:
The GCWR rating includes a 68 kg allowance
for the presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and
rear axles. Distribute the load over the front and rear
axles evenly. Make sure that you do not exceed either
front or rear GAWR.
WARNING!
It is important that you do not exceed
the m
aximum front or rear GAWR. A
dangerous driving condition can result if either
rating is exceeded. You could lose control of the
vehicle and have an accident .

(Continued)
• Vehicles with trailers should not be parked on a
grade.When parking, apply the parking brake on
the tow vehicle. Always, block or "chock" the
trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the
tow vehicle and the trailer such that the following
four ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch uti- lized.
Towing Requirements – Tires
– Do not attempt to tow a trailer while using a compact spare tire.
– Proper tire inflation pressures are essential for the safe and satisfactory operation of your vehicle. Refer
to “Tires – General Information” in “Technical Speci-
fications” for proper tire inflation procedures.
– Check the trailer tires for proper tire inflation pres- sures before trailer usage. – Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Technical Specifications” for the
proper tire inspection procedures.
– When replacing tires, refer to “Tires – General Information” in “Technical Specifications” for proper
tire replacement procedures. Replacing tires with a
higher load carrying capacity will not increase the
vehicle's GVWR and GAWR limits.
Towing Requirements – Trailer Brakes
–Do notinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the
trailer. This could cause inadequate braking and pos-
sible personal injury.
– When towing a trailer equipped with a hydraulic surge actuated brake system, an electronic brake
controller is not required.
– Trailer brakes are recommended for trailers over 450 kg and required for trailers in excess of 750 kg.
If the trailer weighs more than 450 kg
loaded, it should have its own brakes, and
they should be of adequate capacity. Fail-
ure to do this could lead to accelerated brake
lining wear, higher brake pedal effort , and longer
stopping distances.
