Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
Roadside Assistance Program on page 7-5.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see
Recreational Vehicle Towing on page 4-32.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle
- such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy towing” (towing your
vehicle with all four wheels on the ground) and “dolly
towing” (towing your vehicle with two wheels on
the ground and two wheels up on a device known
as a “dolly”). With the proper preparation and
equipment, many
vehicles can be towed
in these ways. See “Dinghy
Towing” and “Dolly Towing,” following.
Here are some important things to consider before you
do recreational vehicle towing:

What’s the towing capacity of the towing vehicle?
Be sure you read the tow vehicle manufacturer’s
recommendations.
How far will you tow? Some vehicles have
restrictions on how far and how long they can tow.
Do you have the proper towing equipment?
See your dealer or trailering professional for
additional advice and equipment recommendations.
Is your vehicle ready to be towed? Just as you
would prepare your vehicle for a long trip, you’ll
want to make sure your vehicle is prepared to be
towed. See
Before Leaving on a Long Trip on
page 4-23.

Towing a Trailer
Y
If you don’t use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well
-- or even
I at all. You and your passengers could be
~ seriously injured. You may also damage your
vehicle; the resulting repairs would not be
covered by your warranty. Pull a trailer only
if
you have followed all the steps in this section.
Ask your dealer for advice and information
about towing a trailer with your vehicle.
Your vehicle can tow a trailer
if it is equipped with the
proper trailer towing equipment. To identify what
the vehicle trailerinq capacity is for Vour vehicle, vou
should read the information in “Weight of the Trailer” that
appears later in this section. But trailering is different
than just driving your vehicle by itself. Trailering means
changes in handling, durability and fuel economy.
Successful, safe trailering takes correct equipment, and
It has to he L!sed proper!)/.
That’s the reason for this part. In it are many time-tested,
important trailering tips and safety rules. Many of
these are important for your safety and that of your
passengers.
So please read this section carefully before
you pull a trailer.
Load-pulling components such as the engine, transaxle,
wheel assemblies and tires are forced to work harder
against the drag
of the added weight. The engine
is required to operate at relatively higher speeds and
under greater loads, generating extra heat. What’s more,
the trailer adds considerably to wind resistance,
increasing the pulling requirements.
If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live
but also where you’ll be driving.
A good source for
this information can be state or provincial police.
Consider using a sway control. You can ask a hitch
dealer about sway controls.

Don’t tow a trailer at all during the first 1,000 miles
(1
600 km) your new vehicle is driven. Your
engine, axle or other parts could be damaged.
Then, during the first 500 miles (800 km) that you
tow a trailer, don’t drive over 50 mph (80 km/h)
and don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at
the heavier loads.
Obey speed limit restrictions when towing a trailer. Don’t drive faster than the maximum posted speed
for trailers, or no more than 55 mph (90 km/h),
to save wear on your vehicle’s parts.
Three important considerations have
to do with weight:
0 the weight of the trailer,
0 the weight of the trailer tongue
0 and the total weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 Ibs. (454 kg). But
even that can be
too heavy.
It depends on how you plan
to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used
to pull
a trailer are all important. And, it can also depend
on any special equipment that you have on your vehicle. You can

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo you
may carry in it, and the people who will be riding in
the vehicle. And
if you tow a trailer, you must add the
tongue load to the GVW because your vehicle will
be carrying that weight,
too. See Loading Your Vehicle
on page 4-35 for more information about your
vehicle’s maximum load capacity.
