9-64 Driving and Operating
5. Remove the key and install the
protective cover.
Check that the hitch is correctly
installed:
Red marking on knob points
towards white marking on hitch.
There is no gap between the
knob and the hitch.
The hitch is seated firmly in the
housing.
The hitch must be locked and
the key removed.
Removing the Hitch
1. Pull the knob out and turn it
clockwise as far as it will go.
2. Pull the hitch downwards out of
the coupling housing and store it
in a safe place.
3. Insert the plug in the housing.
Safety Chains
Always attach chains between the
vehicle and the trailer. 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 rig can turn. Never allow safety
chains to drag on the ground.
Trailer Brakes
A loaded trailer that weighs more
than 450 kg (1,000 lbs) needs to
have its own brake system that is
adequate for the weight of the
trailer. Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted and
maintained properly.
Because the vehicle has anti-lock
brakes, do not tap into the vehicle's
brake system. If you do, both brake
systems will not work well, or at all.
Trailer Wiring Harness
See your dealer/retailer or towing
professional for information on
preparing the vehicle for trailer
towing.
