Secondary Latch System - GMC 2003 Envoy XL Owner's Manual

Secondary Latch System
Your vehicle has an underbody mounted tire hoist
assembly equipped with a secondary latch system.
It's designed to stop the spare or flat road tire
from suddenly falling off your vehicle if the cable holding
the spare tire is damaged. For the secondary latch to
work, the spare tire must be stored with the valve
stem pointing up. See "Storing a Flat or Spare Tire and
Tools" for instructions on storing the spare tire
correctly.
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 below.
Someone standing too dose 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 the spare.
To release the spare tire from the secondary latch do
the following:
1. Check under the
vehicle to see if
the cable is visible.
