To identify the trailering capacity of your vehicle,
you should read the information in "Weight of the
Trailer" that appears later in this section. Trailering
is different than just driving your vehicle by itself.
Trailering means changes in handling, acceleration,
braking, durability and fuel economy. Successful,
safe trailering takes correct equipment, and it has to
be used properly.
That is 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. Also, 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 will 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.
•
Do not 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, do not drive over 50 mph
(80 km/h) and do not 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. Do not 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.
