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 0162.
{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 automatictransmission 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.
4. Do not allow passengers to remain in the vehicle.
(Continued)
Warning (Continued)
5. Place wheel blocks,if equipped, 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 0309. To
use the tire sealant and compressor
kit, see Tire Sealant and
Compressor Kit 0296 orTire
Sealant and Compressor Kit 0302.
When the vehicle has a flat tire (2),
use the following example as a
guide to assist you in the placement
of wheel blocks (1), if equipped.

2. Flat Tire
The following information explains
how to repair or change a tire.
Tire Sealant and
Compressor Kit
Your vehicle may have one of the
two inflator kits described following.
{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)(Continued)
Warning (Continued)
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 0193.
{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 4 mm (0.16 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

4. Remove the plug from thesealant canister inlet valve (2)
and from the sealant
canister (1).
Screw the sealant canister (1)
onto the sealant canister inlet
valve (2) without removing the
tinfoil from the canister.
5. Remove the valve stem cap from the flat tire by turning it
counterclockwise.
Make sure the tire valve stem
is positioned close to the
ground so the hose will
reach it.6. Remove the protective cap and
attach the sealant/air hose (6)
to the tire valve stem by turning
it clockwise until tight.
7. Plug the power plug (5) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets 0120.
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.
8. Start the vehicle. The vehicle must be running while using
the air compressor.
9. Press the on/off button (7) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (3) 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
gauge (3). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure 0281.

Buick Regal Owner Manual (GMNA-Localizing-2nd Timed Print-U.S./Canada-
11486030) - 2018 - crc - 3/23/18
Vehicle Care 299
The pressure gauge (3) 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.
Caution
If the recommended pressure
cannot be reached after
approximately 10 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. SeeRoadside
Assistance Program 0350.
11. Press the on/off button (7) 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 12–14 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 (5) from the accessory power outlet in
the vehicle.
13. Turn the sealant/air hose (6) counterclockwise to remove it
from the tire valve stem.
14. Replace the tire valve stem cap.
15. Immediately drive the vehicle 8 km (5 mi) but not longer than
10 minutes to distribute the
sealant in the tire.
16. Stop at a safe location and check the tire pressure. Refer
to Steps 1–10 under “Using theTire 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.
See
Roadside Assistance
Program 0350.
If the tire pressure has not
dropped more than 68 kPa
(10 psi) from the recommended
inflation pressure, inflate the
tire to the recommended
inflation pressure by using the
compressor to increase the
pressure or turn the air release
valve counterclockwise at the
air filler hose to decrease the
pressure.

18. Turn the sealant/air hose (2)clockwise onto the sealant
canister inlet valve (4) to
prevent sealant leakage.
19. Return the air only hose (11) and power plug (10) back to
their original storage location.
20. If the flat tire was able to inflate
