To release the spare tire from the
secondary latch:
WARNING
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.
1. Check under the vehicle to see if
the cable end is visible.
If the cable is not visible, start
this procedure at Step 6.
2. Turn the hoist extension
counterclockwise until
approximately 15 cm (6 in) of
cable is exposed.
Vehicle Care
3. Attach the jack handle/jack
handle extension and wheel
wrench to the jack.
4. Place the jack under the vehicle,
ahead of the rear bumper.
Position the center lift point of
the jack under the center of the
spare tire and turn the handle
clockwise to raise the jack until it
lifts the secondary latch spring.
