lock GMC YUKON 2005 Owner's Manual

The TPM sensor matching process is outlined below:
1. Set the Parking brake.
2. Turn the ignition switch to RUN with the engine off.
3. Turn the exterior lamp switch from “Off” to “On”
four times within 3 seconds. A double horn chirp
will sound and the TPM low tire warning light
will begin to ash. The double horn chirp and
ashing TPM warning light indicate that the TPM
matching process has started. The TPM warning
light should continue ashing throughout the
matching procedure. The SERVICE TIRE
MONITOR message will be displayed on the
Driver Information Center (DIC).
4. Start with the left (driver’s side) front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPM sensor by increasing or
decreasing the tire’s air pressure for 10 seconds,
then stop and listen for a single horn chirp.
The single horn chirp should sound within
15 seconds, conrming that the sensor identication
code has been matched to this tire and wheel
position. If you do not hear the conrming single
horn chirp, you will need to start over with step
number one. To let air-pressure out of a tire you can
use the pointy end of the valve cap, a pencil-style
air pressure gage or a key.6. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in Step 5.
7. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in Step 5.
8. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in Step 5.
9. After hearing the conrming horn chirp for the left
rear tire, check to see if the TPM warning light is
still ashing. If yes, turn the ignition switch to LOCK.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems
The spare tire does not have a TPM sensor. If you
replace one of the road tires with the spare, the CHECK
TIRE PRESSURE message will be displayed on the
DIC screen. This message should go off once you
re-install the road tire containing the TPM sensor. The
SERVICE TIRE MONITOR message is displayed
when the TPM system is malfunctioning. One or more
missing or inoperable TPM sensors will cause the
service tire monitor message to be displayed. See your
dealer for service.

{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
To be even more certain the vehicle will not
move, you should put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire, on the
other side, at the opposite end of the vehicle.When your vehicle has a at tire, use the following
example as a guide to assist you in the placement of
wheel blocks.
The following information will tell you next how to use
the jack and change a tire.

1. Open the spare tire lock cover on the bumper and
use the ignition key to remove the lock if your
vehicle is equipped with a hoist lock (J).
2. Assemble the wheel wrench (H) and the two jack
handle extensions (I) as shown.3. Insert the hoist end
(open end) (F) of the
extension through
the hole (G) in the
rear bumper.
Be sure the hoist end of the extension connects to
the hoist shaft (E). The ribbed square end of the
extension is used to lower the spare tire.
4. Turn the wheel wrench (H) counterclockwise to
lower the spare tire to the ground. Continue to
turn the wheel wrench until the spare tire can be
pulled out from under the vehicle.
If the spare tire does not lower to the ground, the
secondary latch is engaged causing the tire
not to lower. SeeSecondary Latch System on
page 5-87.

5. Use the wheel wrench
which has a hook that
allows you to pull the
hoist cable towards you
to assist in reaching the
spare tire.
6. Tilt the retainer (D) at
the end of the cable
when the tire has been
lowered, so it can
be pulled up through
the wheel opening.
7. Put the spare tire near the at tire.Removing the Flat Tire and
Installing the Spare Tire
Use the following pictures and instructions to remove
the at tire and raise the vehicle.
The tools you’ll be using include the bottle jack (A), the
wheel blocks (B), the jack handle (C), the jack handle
extensions (D), and the wheel wrench (E).
5-81

1. Remove the center cap by placing the chisel end of
the wheel wrench in the slot on the wheel and
gently prying the cap out.
If the wheel has bolt-on wheel covers, loosen the
plastic nut caps by turning the wheel wrench
in a counterclockwise direction. If needed, nish
loosening them by hand. The nut caps will not come
off. Using the at end of the wheel wrench, pry
along the edge of the cover until it comes off.2. Use the wheel wrench to loosen all the wheel nuts.
Turn the wheel wrench counterclockwise to loosen
the wheel nuts. Don’t remove the wheel nuts yet.
Notice:If your vehicle has QUADRASTEER™ and
you use a jack to raise the vehicle without
positioning it correctly, you could damage the
QUADRASTEER™ system. When raising your
vehicle on a jack, avoid contact with tie rods and
tie rod boots.

3. Position the jack under the vehicle as shown.
Front Tire Flat:If the at tire is on a front tire of
the vehicle, you’ll need to use the jack handle (C)
and only one jack handle extension (D). Attach
the wheel wrench to the jack handle extension.
Attach the jack handle to the jack. Position the jack
on the frame behind the at tire where the frame
sections overlap. Turn the wheel wrench clockwise
to raise the vehicle. Raise the vehicle far enough
off the ground so there is enough room for the spare
tire to clear the ground.Rear Tire Flat:If the at tire is on a rear tire of the
vehicle, you’ll need to use the jack handle (C)
and both jack handle extensions (D). Attach the
wheel wrench to the jack handle extensions. Attach
the jack handle to the jack. Use the jacking pad
provided on the rear axle. Turn the wheel wrench
clockwise to raise the vehicle. Raise the vehicle
far enough off the ground so there is enough room
for the spare tire to clear the ground. Front Position

6. Put the wheel nuts back
on with the rounded
end of the nuts toward
the wheel after
mounting the spare.
7. Tighten each wheel nut by hand. Then use the
wheel wrench to tighten the nuts until the wheel
is held against the hub.
8. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose
and even come off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM 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 5-114for 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 5-114for the wheel nut
torque specication.
5-86

9. 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 either the center cap, or bolt-on hub
cap, depending on what your vehicle is equipped
with. For center caps, place the cap on the wheel and
tap it into place until it seats ush with the wheel.
The cap only goes on one way. Be sure to line up the
tab on the center cap with the indentation on the wheel.
For bolt-on hub caps, align the plastic nut caps with
the wheel nuts and then tighten by hand. Then use the
wheel wrench to tighten.
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 5-91.
{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 below.
