GMC YUKON HYBRID 2009 Manual Online

Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inate a
Punctured Tire
Follow the directions closely for correct sealant usage.
When using the tire sealant and compressor kit during
cold temperatures, warm the kit in a heated environment
for 5 minutes. This will help to inflate the tire faster.Always do a safety check first. SeeIf a Tire Goes Flat
on page 5-30. Do not remove any objects that have
penetrated the tire.
1. Remove the tire sealant and compressor kit from its
storage location. SeeTire Sealant and Compressor
Kit Storage on page 5-50.
2. Unwrap the sealant/air hose (F) and the power
plug (H).
3. Place the kit on the ground.
4. Remove the valve stem cap from the flat tire by
turning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve
stem. Turn it clockwise until it is tight.
6. Plug the power plug (H) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. See “Accessory Power
Outlet(s) in the owner manual.”
If the vehicle has an accessory power outlet, do not
use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.
5-45

7. Start the vehicle. The vehicle must be running while
using the air compressor.
8. Turn the selector switch (A) counterclockwise to the
Sealant + Air position.
9. Press the on/off (B) button to turn the tire sealant
and compressor kit on.
The compressor will inject sealant and air into
the tire.
The pressure gage (C) will initially show a high
pressure while the compressor pushes the sealant
into the tire. Once the sealant is completely
dispersed into the tire, the pressure will quickly drop
and start to rise again as the tire inflates with air only.
10. Inflate the tire to the recommended inflation pressure
using the pressure gage (C). The recommended
inflation pressure can be found on the Tire and
Loading Information label. SeeInflation - Tire
Pressure on page 5-24.
The pressure gage (C) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate pressure
reading. The compressor may be turned on/off
until the correct pressure is reached.Notice:If the recommended pressure cannot be
reached after approximately 25 minutes, the vehicle
should not be driven farther. The tire is too severely
damaged and the tire sealant and compressor kit
cannot inate the tire. Remove the power plug from
the accessory power outlet and unscrew the inating
hose from the tire valve. See “Roadside Assistance
Program” in the owner manual.
11. Press the on/off button (B) to turn the tire sealant
and compressor kit off.
The tire is not sealed and will continue to leak air until
the vehicle is driven and the sealant is distributed in
the tire, therefore, Steps 12 through 18 must be done
immediately after Step 11.
Be careful while handling the tire sealant and
compressor kit as it could be warm after usage.
12. Unplug the power plug (H) from the accessory
power outlet in the vehicle.
13. Turn the sealant/air hose (F) counterclockwise to
remove it from the tire valve stem.
14. Replace the tire valve stem cap.
15. Replace the sealant/air hose (F), and the power
plug (H) back in their original location.
5-46

16. If the flat tire was able
to inflate to the
recommended inflation
pressure, remove
the maximum speed
label from the sealant
canister (E) and
place it in a highly
visible location.
The label is a reminder not to exceed 55 mph
(90 km/h) until the damaged tire is repaired
or replaced.
17. Return the equipment to its original storage location
in the vehicle.
18. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant in the tire.
19. Stop at a safe location and check the tire pressure.
Refer to Steps 1 through 11 under “Using the Tire
Sealant and Compressor Kit without Sealant to
Inflate a Tire (Not Punctured).”If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended inflation pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant cannot seal the tire.
See “Roadside Assistance Program” in the
owner manual.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended inflation
pressure, inflate the tire to the recommended
inflation pressure.
20. Wipe off any sealant from the wheel, tire, and
vehicle.
21. Dispose of the used sealant canister (E) and
sealant/air hose (F) assembly at a local
dealer/retailer or in accordance with local state
codes and practices.
22. Replace it with a new canister available from your
dealer/retailer.
23. After temporarily sealing a tire using the tire sealant
and compressor kit, take the vehicle to an authorized
dealer/retailer within a 100 miles (161 km) of driving
to have the tire repaired or replaced.

Using the Tire Sealant and Compressor
Kit without Sealant to Inate a Tire
(Not Punctured)
To use the air compressor to inflate a tire with air only
and not sealant:Always do a safety check first. SeeIf a Tire Goes Flat
on page 5-30.
1. Remove the tire sealant and compressor kit from its
storage location. SeeTire Sealant and Compressor
Kit Storage on page 5-50.
2. Unwrap the air only hose (G) and the power
plug (H).
3. Place the kit on the ground.
4. Remove the tire valve stem cap from the flat tire by
turning it counterclockwise.
5. Attach the air only hose (G) onto the tire valve stem
by turning it clockwise until it is tight.
6. Plug the power plug (H) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. See “Accessory Power
Outlet(s) in the owner manual.”
If the vehicle has an accessory power outlet, do not
use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.
5-48

7. Start the vehicle. The vehicle must be running while
using the air compressor.
8. Turn the selector switch (A) clockwise to the Air
Only position.
9. Press the on/off (B) button to turn the compressor on.
The compressor will inflate the tire with air only.
10. Inflate the tire to the recommended inflation pressure
using the pressure gage (C). The recommended
inflation pressure can be found on the Tire and
Loading Information label. SeeInflation - Tire
Pressure on page 5-24.
The pressure gage (C) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate reading.
The compressor may be turned on/off until the
correct pressure is reached.
If you inflate the tire higher than the recommended
pressure you can adjust the excess pressure by
pressing the pressure deflation button (D) until the
proper pressure reading is reached. This option
is only functional when using the air only hose (G).
11. Press the on/off button (B) to turn the tire sealant
and compressor kit off.
Be careful while handling the tire sealant and
compressor kit as it could be warm after usage.12. Unplug the power plug (H) from the accessory
power outlet in the vehicle.
13. Disconnect the air only hose (G) from the tire valve
stem, by turning it counterclockwise, and replace
the tire valve stem cap.
14. Replace the air only hose (G) and the power
plug (H) and cord back in its original location.
15. Place the equipment in the original storage location
in the vehicle.
The tire sealant and compressor kit has an accessory
adapter located in a compartment on the bottom of
its housing that may be used to inflate air mattresses,
balls, etc.
