Driving Characteristics
and Towing Tips
Pulling a Trailer
Here are some important points:
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 in Towing
Equipment on page 9 76.
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.
Then, 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.
If the vehicle has the Side Blind
Zone Alert (SBZA) system and it
doesn't seem to be working
properly while pulling a trailer,
turn the system off. See Side
Blind Zone Alert (SBZA) on
page 9 54 for more information.

Important considerations that have
to do with weight:
The weight of the trailer
The weight of the trailer tongue
The weight on the vehicle's tires
And the weight of the trailering
combination
Driving with a Trailer
WARNING
When towing a trailer, exhaust
gases may collect at the rear of
the vehicle and enter if the
liftgate, trunk/hatch, or rear-most
window is open.
Engine exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
