Replace wheels, wheel bolts, wheel
nuts, or Tire Pressure Monitor
System (TPMS) sensors with new
GM original equipment parts.
{WARNING
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling of
the vehicle. Tires can lose air,
and cause loss of control, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
Notice: The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration,
headlamp aim, bumper height,
vehicle ground clearance, and tire
or tire chain clearance to the
body and chassis.
See If a Tire Goes Flat on
page 10‑58 for more information.
Used Replacement Wheels
{WARNING
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{WARNING
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
(Continued)
WARNING (Continued)
parts. The area damaged by the
tire chains could cause loss of
control and a crash.
Use another type of traction
device only if its manufacturer
recommends it for the vehicle's
tire size combination and road
conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive slow
and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the front tires.

If a Tire Goes Flat
It is unusual for a tire to blow out,
especially if the tires are maintained
properly. SeeTires on page 10‑39.
If air goes out of a tire, it is much
more likely to leak out slowly. But if
there is ever a blowout, here are a
few tips about what to expect and
what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible. A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
{WARNING
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has
been driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
{WARNING
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 flat 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 flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard
Warning Flashers on page 6‑3.

Vehicle Care 10-59
{WARNING
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
causing injury or death. Find a
level place to change the tire. To
help prevent the vehicle from
moving:1. Set the parking brake firmly.
2. Put an automatic transmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine and do not restart while the vehicle
is raised.
(Continued)
WARNING (Continued)
4. Do not allow passengers toremain in the vehicle.
5. Place wheel blocks on both sides of the tire at the
opposite corner of the tire
being changed.
This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. To use the jacking
equipment to change a spare tire
safely, follow the instructions below.
Then see Tire Changing on
page 10‑67. To use the tire sealant
and compressor kit, see Tire
Sealant and Compressor Kit on
page 10‑60. When the vehicle has a flat tire (B),
use the following example as a
guide to assist you in the placement
of wheel blocks (A).

The following information explains
how to repair or change a tire.
Tire Sealant and
Compressor Kit
{WARNING
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains carbon monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation. For
more information, seeEngine
Exhaust on page 9‑22.
{WARNING
Overinflating a tire could cause
the tire to rupture and you or
others could be injured. Be sure
to read and follow the tire sealant
and compressor kit instructions
and inflate the tire to its
recommended pressure. Do not
exceed the recommended
pressure.
{WARNING
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 its
original location. If this vehicle has a tire sealant
and compressor kit, there may not
be a spare tire or tire changing
equipment, and on some vehicles
there may not be a place to store
a tire.
The tire sealant and compressor
can be used to temporarily seal
punctures up to 6 mm (0.25 in) in
the tread area of the tire. It can also
be used to inflate an
underinflated tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a large puncture, the tire is
too severely damaged for the tire
sealant and compressor kit to be
effective. See
Roadside Assistance
Program on page 13‑5.
Read and follow all of the tire
sealant and compressor kit
instructions.

Check the tire sealant expiration
date on the tire sealant canister.
The tire sealant canister should be
replaced before its expiration date.
Replacement tire sealant canisters
are available at your local dealer.There is only enough sealant to seal
one tire. After usage, the tire sealant
canister must be replaced.
Using the Tire Sealant and
Compressor Kit to Temporarily
Seal and Inflate a
Punctured Tire
When using the tire sealant and
compressor kit during cold
temperatures, warm the kit in a
heated environment for five minutes.
This will help to inflate the tire
faster.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. See
Hazard
Warning Flashers on page 6‑3.
See If a Tire Goes Flat on
page 10‑58 for other important
safety warnings.

10-62 Vehicle Care
Do not remove any objects that
have penetrated the tire.
1. Remove the tire sealant canisterand compressor from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑67.
2. Remove the air only hose (J) and the power plug (I) from the
bottom of the compressor.
3. Place the compressor on the ground near the flat tire.
4. Attach the air only hose (J) tothe sealant canister inlet
valve (A) by turning it clockwise
until tight.5. Slide the base of the tire sealantcanister (C) into the slot on the
top of the compressor (F) to hold
it upright.
Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
6. Remove the valve stem cap from the flat tire by turning it
counterclockwise.

Vehicle Care 10-63
7. Attach the sealant/air hose (B) tothe tire valve stem by turning it
clockwise until tight.
8. Plug the power plug (I) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets on page 5‑5.
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.
9. Start the vehicle. The vehicle must be running while using the
air compressor.
10. Press the on/off button (E) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (H) 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.
11. Inflate the tire to the recommended inflation
pressure using the pressure
gauge (H). The recommended
inflation pressure can be found on the Tire and Loading
Information label. See
Tire
Pressure on page 10‑45.
The pressure gauge (H) 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 inflate the
tire. Remove the power plug from
the accessory power outlet and
unscrew the inflating hose from
the tire valve. See Roadside
Assistance Program on
page 13‑5.
12. Press the on/off button (E) to turn the tire sealant and
compressor kit off.

Black plate (64,1)Chevrolet Sonic Owner Manual - 2012
10-64 Vehicle Care
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 13 through
21 must be done immediately
after Step 12.
Be careful while handling the
tire sealant and compressor kit
as it could be warm after
usage.
13. Unplug the power plug (I) from the accessory power outlet in
the vehicle.
14. Turn the sealant/air hose (B) counterclockwise to remove it
from the tire valve stem.
15. Replace the tire valve stem cap.
16. Remove the tire sealant canister (D) from the slot on
top of the compressor (F). 17. Turn the air only hose (J)
counterclockwise to remove it
from the tire sealant canister
inlet valve (A).
18. Turn the sealant/air hose (B) clockwise onto the sealant
canister inlet valve (A) to
prevent sealant leakage.
19. Return the air only hose (J) and power plug (I) back to their
original storage location.
20. If the flat tire was able to inflateto the recommended inflation
pressure, remove the
maximum speed label from the
sealant canister and place it in
a highly visible location.
Do not exceed the speed on
this label until the damaged tire
is repaired or replaced. 21. Return the equipment to its
original storage location in the
vehicle.
22. Immediately drive the vehicle 8 km (5 mi) to distribute the
sealant in the tire.
23. Stop at a safe location and check the tire pressure. Refer
to Steps 1 through 10 under
“Using the Tire Sealant and
Compressor Kit without Sealant
to Inflate a Tire (Not
Punctured).”
If the tire pressure has fallen
more than 68 kPa (10 psi)
below the recommended
inflation pressure, stop driving
the vehicle. The tire is too
severely damaged and the tire
sealant cannot seal the tire.
