2009 CADILLAC SRX wheel

If the spare tire will not lower, the secondary latch might
be engaged causing the tire not to lower. Do the
following to check the cable:
1. Check under the
vehicle to see if the
cable is visible. If it is
not visible, see
Secondary Latch
System on page 5-82.2. 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
over-tighten the cable.
3. Loosen the cable then by turning the wrench
counterclockwise three or four turns.
4. Tighten the cable all the way and then loosen it at
least two times, if the spare tire has not lowered.
If the spare tire did lower to the ground, continue
with Step 4 underRemoving the Spare Tire
and Tools on page 5-75.
If you still cannot lower the spare tire to the ground, see
Secondary Latch System on page 5-82.

Removing the Flat Tire and
Installing the Spare Tire
To remove the at tire and install the spare:
1. Do a safety check before proceeding. SeeChanging
a Flat Tire on page 5-74for more information.
2. Loosen the wheel nuts, but do not remove them
yet, using the wheel wrench. Turn the handle
about 180 degrees, then ip the handle back to the
starting position. This avoids taking the wrench
off the lug nut for each turn.3. Find the jacking location using the V–shaped
notches located in the plastic molding.
4. Attach the wheel wrench to the jack.
{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under a
vehicle when it is supported only by a jack.
5-78

{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even make
the vehicle fall. To help avoid personal injury and
vehicle damage, be sure to t the jack lift head into
the proper location before raising the vehicle.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without the
appropriate safety equipment and training. If a jack
is provided with the vehicle, it is designed only for
changing a at tire. If it is used for anything else,
you or others could be badly injured or killed if the
vehicle slips off the jack. If a jack is provided with
the vehicle, only use it for changing a at tire.
5. Turn the wheel wrench clockwise to raise the jack
lift head until the jack just ts under the vehicle.6. Raise the jack by turning the wheel wrench
clockwise until the slots in the jack head t into the
metal ange located behind the triangle on the
plastic molding as shown.
Notice:Using a jack to raise the vehicle without
positioning it correctly could damage your vehicle.
When raising your vehicle on a jack, be sure to
position it correctly under the frame and avoid
contact with the plastic molding.
7. Put the compact spare tire near you.
5-79

8. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground for the compact spare tire to t under the
vehicle.9. Remove all the wheel
nuts and the at tire.
10. Remove any rust or dirt
from the wheel bolts,
mounting surfaces, and
spare wheel.
5-80

{CAUTION:
Rust or dirt on a wheel, or on the parts to which it
is fastened, can make wheel nuts become loose
after time. The wheel could come off and cause
an accident. When changing a wheel, remove any
rust or dirt from places where the wheel attaches
to the vehicle. In an emergency, use a cloth or
a paper towel to do this; but be sure to use a
scraper or wire brush later, if needed, to get all
the rust or dirt off. SeeChanging a Flat Tire on
page 5-74.
{CAUTION:
Never use oil or grease on bolts or nuts because
the nuts might come loose. The vehicle’s wheel
could fall off, causing a crash.
11. Install the spare tire.
12. Put the wheel nuts back on with the rounded end of
the nuts toward the wheel.
13. Tighten each nut by hand until the wheel is held
against the hub.
14. Lower the vehicle by attaching the wheel wrench to
the jack and turning the wrench counterclockwise.
Lower the jack completely.
5-81

15. Tighten the wheel nuts
rmly in a crisscross
sequence, as shown.
{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 5-109
for 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.
16. Do not try to put a wheel cover on the compact
spare tire. It will not t. Store the wheel cover
securely in the rear of the vehicle until you have
the at tire repaired or replaced.
Secondary Latch System
Your vehicle has an underbody mounted tire hoist
assembly that has a secondary latch system. It is
designed to stop the compact spare 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 down.
SeeStoring a Flat or Spare Tire and Tools on
page 5-85for instructions on storing the spare tire
correctly.

{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 the under spare.To release the spare tire from the secondary latch:
1. If the cable is not visible, start this procedure
at Step 3.
2. If the cable is visible,
place the wrench on
the hoist drive nut
and turn the wrench
counterclockwise
until approximately
6 inches (15 cm)
of cable is exposed.
3. Attach the wheel wrench to the jack and raise the
jack at least 10 turns.
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.

5. Turn the wheel wrench clockwise to raise the jack
until it lifts the secondary latch spring.
6. Keep raising the jack until the spare tire stops
moving upward and is held rmly in place, this lets
you know that the secondary latch has released.
7. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until
the spare tire is resting on the wheel wrench.8. Grasp the spare tire with both hands and pull it out
from under the vehicle.
