Secondary Latch System - Chevrolet 2009 Silverado Owner's Manual

Secondary Latch System

Your vehicle has an underbody-mounted tire hoist
assembly equipped with 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. See Storing a Flat or Spare Tire and Tools on
page 5-108.
CAUTION:
{
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:
2. 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.
3. Loosen the cable by turning the 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 of
Removing the Spare Tire and Tools on page 5-93.
5. If the spare does not lower, turn the wrench
counterclockwise until approximately 6 inches
(15 cm) of cable is exposed.
1. Check under the
vehicle to see if the
cable end is visible.
If the cable is not
visible proceed
to Step 6.
