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 tire must be stowed with the valve stem
pointing up. See "Storing a Flat or Spare Tire and Tools"
for instructions on storing the spare or flat 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 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 the spare.
