2008 CHEVROLET HHR Owners Manual

If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain your vehicle’s tires properly.
If air goes out of a tire, it is much more likely to leak out
slowly. But if you should ever have a blowout, here
are a few tips about what to expect and what to do:
If a front tire fails, the at tire creates a drag that pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you would
use in a skid. In any rear blowout remove your foot from
the accelerator pedal. Get the vehicle under control
by steering the way you want the vehicle to go. It may
be very bumpy and noisy, but you can still steer.
Gently brake to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle 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. Use the jack provided with your
vehicle only for changing a at tire.
If a tire goes at, the next part shows how to use the
jacking equipment to change a at tire safely.

Tire Sealant and Compressor Kit
Your vehicle may have a tire sealant and compressor kit
that is capable of temporarily sealing a puncture up to
14inch (6 mm) in the tread area of the tire. If your vehicle
has this kit, there is no jack or spare tire. The kit inates
the tire with liquid sealant and air. The tire sealant and
compressor kit can also be used to inate an
underinated tire. After the tire is inated to the
recommended ination pressure, seeInflation - Tire
Pressure on page 5-60for more information, the vehicle
must be driven for ve miles to distribute the sealant in
the tire and to seal the puncture. After driving ve miles,
the tire pressure must be rechecked and adjusted as
needed. See Using the Tire Sealant and Compressor
later in this section. Be sure to read and follow all of the
tire sealant and compressor kit instructions. The kit
includes the following:
A. Air Compressor
B. Tire Sealant Canister
C. Air Compressor
Accessory Plug
D. On/Off SwitchE. Air Pressure Gage
F. Air Compressor
Inator Hose
G. Sealant Filling Hose
After temporarily repairing a tire using the tire sealant
and compressor kit, take your vehicle to an authorized
dealer/retailer as soon as possible. If the sealant is
not removed from the tire within 100 miles
(161 kilometers) of driving, the dealer/retailer may
recommend that the tire be replaced.

Accessing the Tire Sealant and
Compressor Kit
To access the tire sealant and compressor kit:
1. Open the liftgate. SeeLiftgate on page 2-12for
more information
2. Remove the cargo cover.3. Remove the foam retainer bolt (B) holding down the
foam container.
4. Remove the foam container (C).
5. Remove the sealant and compressor kit (A) from its
foam container.
5-77

Tire Sealant
Read and follow the safety handling instructions on the
sealant canister.
The sealant can temporarily seal a puncture up to
14inch (6 mm) in the tread area of the tire. The sealant
cannot seal sidewall damage, large punctures, or a
tire that has unseated from the wheel. SeeRoadside
Assistance Program on page 7-6if you need assistance.
The sealant can only be used to seal one tire. After
usage, the sealant canister and the sealant lling hose
assembly must be replaced at a dealer/retailer. See
Removal and Installation of Sealant Canister later in this
section.
Check the tire sealant expiration date on the sealant
canister, if it has expired, see your dealer/retailer for a
replacement.
Using the Tire Sealant and Compressor
Kit to Temporarily Seal a Punctured Tire
Follow the directions closely for correct sealant usage.
1. Place the sealant and compressor kit on the ground
and unwrap the sealant lling hose from the
compressor.
2. Remove the air compressor accessory plug from
the unit. To do this, pull the top portion of the
wrapped cord out rst, then the bottom, and then
unsnap the plug. Do not insert the plug into an
accessory outlet yet.
3. Remove the valve stem or tire pressure monitoring
sensor cap from the at tire by turning it
counterclockwise.
If an object, such as a nail, has penetrated the tire,
do not remove it.
5-78

4. Attach the sealant lling hose (A) onto the tire valve
stem. Turn it clockwise until it is tight.
Make sure the sealant and compressor kit on/off
switch (B) is in the O (off) position.
5. Plug the air compressor accessory plug (C) into an
accessory power outlet in the vehicle. SeeAccessory
Power Outlet(s) on page 3-20for more information.
Do not slam door or close window on the
compressor accessory plug cord.
{CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause
deadly carbon monoxide (CO). SeeEngine
Exhaust on page 2-37.
6. Start the vehicle. SeeStarting the Engine (Key
Access) on page 2-25for more information.
The vehicle must be running while using the air
compressor.
{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions, and
inate the tire to its recommended pressure.
Do not exceed 36 psi (248 kPa).
5-79

7. Push the On/Off switch to the I (on) position.
The sealant and compressor kit injects sealant
and air into the tire. Sealant can leak from
the puncture until the vehicle is driven and the hole
has sealed.
The pressure gage 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 inates with air.
8. Inate the tire to the recommended ination
pressure, found on the Tire and Loading Information
label located on the vehicle’s center pillar (B-pillar)
below the vehicle’s door latch, using the air pressure
gage on the top of the unit.
The pressure gage reads high while the compressor
is running. Turn the compressor off to get an
accurate pressure reading.
Notice:If the recommended pressure cannot be
reached after 15 minutes, the vehicle should not be
driven farther. Damage to the tire is severe and
the sealant will not be effective. Remove the
air compressor plug from the accessory power
outlet and unscrew the inating hose from the tire
valve. SeeRoadside Assistance Program on
page 7-6for more information.9. Push the sealant and compressor kit switch to the
O (off) position.
10. The tire is not sealed and will continue to leak air
until the vehicle is driven and the sealant is
distributed in the tire.
Steps 11 through 18 must be done right after
Step 9.
11. Unplug the air compressor accessory plug from the
accessory power outlet in the vehicle.
12. Disconnect the sealant lling hose from the tire
valve stem, by turning it counterclockwise, and
replace the tire valve stem cap.
Be careful when handling the tire inator
components as they could be hot after usage.
13. Wrap the sealant lling hose around the air
compressor channel to stow it in its original location.
14. Stow the air compressor accessory plug back in the
air compressor. To do this, wrap the air compressor
accessory plug, snap in the plug, and then push
in the bottom and then the top of the wrapped
air compressor accessory plug.
5-80

15. If the at tire was able
to inate to the
recommended ination
pressure, remove
the maximum speed
label from the sealant
canister.
The maximum speed label reminds you to drive
cautiously and not to exceed 55 mph (90 km/h)
until you have the damaged tire inspected
and repaired.
16. Place it in a highly visible location such as the
inside of the upper left corner of the windshield
or to the face of the radio/clock.
17. Return the equipment to the proper storage location
in the rear of your vehicle. To do this, insert the tire
sealant and compressor kit back into the foam
container and place the foam container onto the
storage bracket. Securely tighten down the
foam container with the foam retainer bolt.
{CAUTION:
Storing the tire sealant and compressor kit
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 the tire sealant
and compressor kit in the proper place.
18. Reverse Steps 1 through 4 under Accessing the
Tire Sealant and Compressor Kit earlier in this
section.
19. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant evenly in the tire. Stop at a
safe location and check the tire pressure, refer
to Steps 1 through 8 under Using the Air
Compressor without Sealant next in this section.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, you can inate the tire back up to
the recommended ination pressure.
5-81

20. If the tire pressure has fallen more then 10 psi
(68 kPa), below the recommended ination
pressure, stop driving the vehicle. The tire is
too severely damaged and the tire sealant and
compressor kit cannot seal the tire. SeeRoadside
Assistance Program on page 7-6for more
information.
21. Wipe off any sealant from the wheel, tire and
vehicle with a rag.
22. Dispose of the sealant canister at a local
dealer/retailer or in accordance with any local, state,
and provincial codes and practices.
After using the sealant canister, replace it with a
new canister from a dealer/retailer.
23. After temporarily sealing a tire with the tire sealant
and compressor kit, take your vehicle to an
authorized dealer/retailer to have the tire inspected
and repaired.Using the Air Compressor without
Sealant to Inate an Underinated Tire
(Not Punctured)
To use the air compressor to inate a tire with air only
and not sealant:
1. Remove the air compressor inating hose connector
from the bottom of the air compressor.
2. Unlock the air compressor hose from the sealant
canister by pulling up on the lever.
3. Pull the air compressor inator hose from the
sealant canister.
