Secondary Latch System - Chevrolet Silverado 2007 Owner's Manual

Notice: Improperly tightened wheel nuts can

Capacities and Specifications on page 626 for
the wheel nut torque specification.

sequence as shown by turning the wheel
wrench clockwise.
When you reinstall the regular wheel and tire, you
must also reinstall either the center cap, or
bolt-on hub cap, depending on what your vehicle
is equipped with. For center caps, place the
cap on the wheel and tap it into place until it seats
flush with the wheel. The cap only goes on one

way. Be sure to line up the tab on the center cap
with the indentation on the wheel. For bolt-on
hub caps, align the plastic nut caps with the wheel
nuts and then tighten by hand. Then use the
wheel wrench to tighten.

Secondary Latch System

Your vehicle has an underbody-mounted tire hoist
assembly which 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 tire must be installed with
the valve stem pointing down. See Storing a Flat
or Spare Tire and Tools on page 602.
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
