2010 GMC CANYON Owner's Manual

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly that has a secondary latch system. It is
designed to stop the spare tire from suddenly falling off
your vehicle. For the secondary latch to work, the spare
must be installed with the valve stem pointing down.
SeeStoring a Flat or Spare Tire and Tools on page 6-96.
{WARNING:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly
and you and others could get hurt. Read and
follow the instructions listed next.To release the spare tire from the secondary latch:
1. Check under the
vehicle to see if the
cable end fitting
is visible.
2. If the cable end fitting is not visible, proceed to
Step 6.
If it is visible, first try to tighten the cable by turning
the wheel wrench clockwise until you hear two clicks
or feel it skip twice. You cannot overtighten the cable.
6-93

3. Loosen the cable by turning the wheel wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times. If the
spare tire lowers to the ground, continue with
Step 5 underRemoving the Spare Tire and Tools
on page 6-81.
5. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable is
exposed.
6. Stand the wheel blocks on their shortest ends,
with the backs facing each other.
7. Place the bottom
edge of the jack (A) on
the wheel blocks (B),
separating them so that
the jack is balanced
securely.8. Attach the jack handle, extension, and wheel
wrench to the jack and place it (with the wheel
blocks) under the vehicle towards the front of the
rear bumper. Position the center lift point of the
jack under the wheel.
9. Turn the wheel wrench clockwise to raise the jack
until it lifts the tire.
10. Continue raising the jack until the tire stops moving
upward and is held firmly in place.
6-94

11. Remove the jack handle and insert the hoist end of
the extension through the hole in the rear bumper.
Turn the wheel wrench counterclockwise one
turn or until the wheel retainer assembly is
disengaged.
12. Reinsert the jack handle into the jack. Lower the
jack by turning the wheel wrench counterclockwise.
Keep lowering the jack until the spare tire slides
off the jack or is hanging by the cable.
{WARNING:
Someone standing too close during the procedure
could be injured by the jack. If the spare tire does
not slide off the jack completely, make sure no
one is behind you or on either side of you as you
pull the jack out from under the spare.
13. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while firmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, insert
the hoist end of the extension into the hoist shaft
hole in the bumper and turn the wheel wrench
counterclockwise to lower the spare the rest of
the way.
6-95

14. Tilt the tire retainer at the end of the cable and pull
it through the wheel opening. Pull the tire out from
under the vehicle.
15. If the cable is hanging under the vehicle, turn the
wheel wrench clockwise to raise the cable.
Have the hoist assembly inspected as soon as you
can. You will not be able to store a spare or flat
tire using the hoist assembly until it has been
replaced.
To continue changing the flat tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 6-85.
