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. See "Hitches"
later in this section.
•
Do not tow a trailer at all during the first
500 miles (800 km) your new vehicle is driven.
Your engine, axle, or other parts could be
damaged.
•
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.
•
You can use THIRD (3) or, as you need to, a
lower gear when towing a trailer. Operating
your vehicle in THIRD (3) when towing a trailer
will minimize heat buildup and extend the
life of your transaxle.
Three important considerations have to do with
weight:
•
Weight of the trailer
•
Weight of the trailer tongue
•
Weight on your vehicle's tires
Weight of the Trailer
How heavy can a trailer safely be?
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. It can also
depend on any special equipment that you have
on your vehicle, and the amount of tongue
weight the vehicle can carry. See "Weight of the
Trailer Tongue" later in this section for more
information.
Maximum trailer weight is calculated assuming
only the driver is in the tow vehicle and it has all
the required trailering equipment. The weight
of additional optional equipment, passengers and
cargo must be subtracted from the maximum
trailer weight.
