2009 CADILLAC SRX Owners Manual

{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.
5-82

{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.
{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.
5-83

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.
9. Reach under the vehicle and remove the wheel
wrench and jack.
5-84

10. Tilt the retainer and slip
it through the wheel
opening when the
spare tire has been
completely lowered.
11. Turn the wrench clockwise to raise the cable back
up if the cable is hanging.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare tire using the
hoist assembly until it has been repaired or replaced.Storing a Flat or Spare Tire and
Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these in
the proper place.
5-85

Storing the Flat Tire with Third Row
Passengers
1. Put back all tools as they were stored in the rear
storage compartment and put the compartment
cover back on.
2. Use the power third row seat button, near the
liftgate, to tilt the third row seatback forward slightly.
3. Place the at tire in the tire storage bag and put the
tire in an upright position against the third row seat.
4. Route the tie-down strap through the tire as shown
in the graphic and attach the strap to the cargo
tie-downs in the rear of the vehicle.
5. Tighten the tie-down strap.
Storing the Flat Tire with a Flat Load
Floor
1. Put back all tools as they were stored in the rear
storage compartment and put the compartment
cover back on.
2. Place the at tire in the tire storage bag and put the
tire in a horizontal position on the oor in the rear of
the vehicle.
3. Route the tie-down strap through the tire as shown
in the graphic and attach the strap to the cargo
tie-downs in the rear of the vehicle.
4. Tighten the tie-down strap.
5-86

Storing the Spare Tire and Tools
{CAUTION:
The underbody-mounted spare tire needs to be
stored with the valve stem pointing down. If the
spare tire is stored with the valve stem pointing
upwards, the secondary latch will not work properly
and the spare tire could loosen and suddenly fall
from the vehicle. If this happened when the vehicle
was being driven, the tire might contact a person or
another vehicle, causing injury and damage to itself.
Be sure the underbody-mounted spare tire is stored
with the valve stem pointing down.
To store the spare tire and tools, do the following:
1. Lay the compact spare tire on the ground at the
rear of the vehicle. Position the compact spare
tire so that the valve stem is pointed down facing
the rear of the vehicle.
2. Lower the cable to the ground. SeeRemoving the
Spare Tire and Tools on page 5-75.3. Tilt the retainer downward and slip it through the
center hole of the spare tire.
Make sure the retainer is fully seated across the
underside of the wheel.
4. Attach the wheel wrench to the hoist shaft.
5. Turn the wheel wrench clockwise to lift the
spare tire.
6. When the tire is almost in the stored position, turn
the tire so that the valve stem is towards the rear of
the vehicle.
This will help when you check and maintain tire
pressure in the spare.
5-87

7. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench until
you feel more than two clicks. This indicates that the
compact spare tire is secure and the cable is
tight. The spare tire hoist cannot be overtightened.
8. Make sure the tire is stored securely. Push, pull (A),
and then try to turn the tire (B). If the tire moves,
use the wheel wrench to tighten the cable.
Put back all tools as they were stored in the rear
storage compartment and put the compartment cover
back on.Compact Spare Tire
Although the compact spare tire was fully inated when
the vehicle was new, it can lose air after a time.
Check the ination pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on the vehicle, you
should stop as soon as possible and make sure the spare
tire is correctly inated. The compact spare is made to
perform well at speeds up to 65 mph (105 km/h) for
distances up to 3,000 miles (5 000 km), so you can nish
your trip and have the full-size tire repaired or replaced
where you want. You must calibrate the tire ination
monitor system after installing or removing the compact
spare. SeeTire Pressure Monitor System on page 5-59.
The system may not work correctly when the compact
spare is installed on the vehicle. Of course, it’s best to
replace the spare with a full-size tire as soon as you can.
The spare will last longer and be in good shape in case
you need it again.
Notice:When the compact spare is installed,
do not take the vehicle through an automatic car
wash with guide rails. The compact spare can
get caught on the rails which can damage the tire,
wheel and other parts of the vehicle.
Do not use the compact spare on other vehicles.
