220 Driving and Operating
Hitch Cover
To remove the hitch cover, if equipped:
1. Turn the two quarter-turn fasteners (2).
2. Pull the bottom edge of the cover rearward.
3. Disengage the cover at the upper
attachments (1) and remove.
Consider using mechanical sway controls
with any trailer. Ask atrailering professional
about sway controls or refer to the
trailer manufacturer's recommendations
and instructions.
Tires
•
Do
not tow atrailer while using acompact
spare tire on the vehicle.
•
Tires must be properly inflated to
support loads while towing atrailer. See
Tires 3249 for instructions on proper
tire 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.
State 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 state to state. 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crash.
Trailer Lamps
Always check 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 turn
signals should 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.
