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. SeeStoring a Flat or Spare Tire and Tools
on page 5-94.
{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:
1. Check under the
vehicle to see if the
cable end is visible.
If the cable is not
visible proceed
to Step 6.
2. If it is visible, rst 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.

lifts the end tting.
11. Continue raising the jack until the spare tire stops
moving upward and is held rmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.
12. 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.
{CAUTION:
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 rmly 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 extension, and wheel wrench into the
hoist shaft hole in the bumper and turn the wheel
wrench counterclockwise to lower the spare the rest
of the way.

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. Turn the wheel wrench in the hoist shaft hole in the
bumper clockwise to raise the cable back up if the
cable is hanging under the vehicle.
Have the hoist assembly inspected as soon as you can.
