Driving Characteristics
and Towing Tips
Pulling a Trailer
Important points for pulling a trailer:
. There are many different laws,
including speed limit restrictions,
having to do with trailering.
Make sure the 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.
See “Hitches” under Towing
Equipment on page 9‑112.
. Do not tow a trailer at all during
the first 800 km (500 miles)
the new vehicle is driven.
The engine, axle, or other
parts could be damaged.
. During the first 800 km
(500 miles) that a trailer is
towed, do not drive over
80 km/h (50 mph) and do
not make starts at full throttle.
This helps the engine and other
parts of the vehicle wear in at
the heavier loads.
. Vehicles can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts
too often under heavy loads
and/or hilly conditions.
Important considerations that have
to do with weight:
. Weight of the trailer
. Weight of the trailer tongue
. Weight on the vehicle's tires
. Weight of the trailering
combination
