Only use towing equipment that has
been designed for the vehicle.
Contact your dealer or trailering
dealer for assistance with preparing
the vehicle for towing a trailer.

information in this section:

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
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
