Tyres
.
Do not tow a trailer while using a
compact spare tyre on the vehicle.
.
Tyres must be properly inflated to
support loads while towing a trailer. See
for instructions on proper
tyre inflation.
Safety Chains
Always attach chains between the vehicle
and the trailer, and attach the chains to the
holes on the trailer hitch platform.
Instructions about safety chains may be
provided by the hitch manufacturer or by
the trailer manufacturer.
Cross the safety chains under the tongue of
the trailer to help prevent the tongue from
contacting the road if it becomes separated
from the hitch. Always leave just enough
slack so the combination can turn. Never
allow safety chains to drag on the ground.
Trailer Brakes
Loaded trailers over 450 kg (1,000 lb) must
be equipped with brake systems and with
brakes for each axle. Trailer braking
equipment conforming to Canadian
Standards Association (CSA) requirement
CAN3-D313, or its equivalent, is
recommended.
Regional or local regulations may require
trailers to have their own braking system if
the loaded weight of the trailer exceeds
certain minimums that can vary from region
to region. Read and follow the instructions
for the trailer brakes so they are installed,
adjusted, and maintained properly. Never
attempt to tap into your vehicle's hydraulic
brake system. If you do, both the vehicle
anti-lock brakes and the trailer brakes may
not function, which could result in a
collision.
Trailer Wiring Harness
Basic Trailer Wiring
The trailer wiring harness is located at the
rear of the vehicle and is tied to the
vehicle's frame. The harness connector can
be plugged into a trailer connector available
through your retailer.
The swivel-style factory installed hitch has a
standard 13-pin connector integrated into the
ball neck that is accessible when the hitch
cover is removed and the hitch is deployed.
Trailer Lamps
Always check that all trailer lamps are
working at the beginning of each trip, and
periodically on longer trips.
Turn Signals When Towing a Trailer
When properly connected, the trailer
indicators will illuminate to indicate the
vehicle is turning, changing lanes,
or stopping. When towing a trailer, the
arrows on the instrument cluster will
illuminate even if the trailer is not properly
connected or the bulbs are burned out.
