2008 CADILLAC ESCALADE EXT Owners Manual

{CAUTION:
Incorrect or improperly tightened wheel
nuts can cause the wheel to come loose and
even come off. This could lead to a crash.
If you have to replace them, be sure to get
new original equipment wheel nuts. Stop
somewhere as soon as you can and have the
nuts tightened with a torque wrench to the
proper torque specication. SeeCapacities
and Specifications on page 5-115for wheel
nut torque specication.
Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage.
To avoid expensive brake repairs, evenly tighten
the wheel nuts in the proper sequence and to
the proper torque specication. SeeCapacities
and Specifications on page 5-115for the wheel
nut torque specication.12. Tighten the
nuts rmly in a
crisscross sequence
as shown by
turning the wheel
wrench clockwise.
When you reinstall the regular wheel and tire, you
must also reinstall the center cap. Line the tab on the
back of the tab with the slot in the wheel. Place the
cap on the wheel and press until it snaps into place.

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.

4. Repeat this procedure at least two times. If the
spare tire lowers to the ground, continue with
Step 5 ofRemoving the Spare Tire and Tools
on page 5-79.
5. If the spare does not lower, turn the wrench
counterclockwise until approximately 6 inches
(15 cm) of cable is exposed.
6. Stand the wheel blocks on their shortest ends,
with the backs facing each other.
7. Place the bottom
edge of the jack (A) on
the wheel blocks (B),

wrench to the jack and place it (with the wheel
blocks) under the vehicle toward the front of the
rear bumper.

9. Position the center lift point of the jack under the
center of the spare tire.10. Turn the wrench clockwise to raise the jack until
it 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.
You will not be able to store a spare or at tire using
the hoist assembly until it has been replaced.
