Handling the Unexpected
Temporarily Repairing a Flat Tire*
If the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a small puncture, from a nail for instance, you can
use the temporary tire repair kit so that you can drive to the nearest service station
for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and n on-slippery surface and apply the parking
brake.
2. Move the shift lever to
(P.
3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF
(LOCK).
1Temporarily Repairing a Flat Tire*
The kit should not be used in the following situations.
Instead, contact a dealer or a roadside assistant to
have the vehicle towed.
•The tire sealant has expired.
•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4mm).
•The tire side wall is da maged or the puncture is
outside the contact area.
•Damage has been caused by driving with the tire
extremely under inflated.
•The tire bead is no longer seated.
•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.
NOTICE
Do not use a puncture-repairing agent other than the
one provided in the kit that came with your vehicle. If
a different agent is used, you may permanently
damage the tire pressure sensor.

7. Press the inflator switch to turn on the
compressor.
u The compressor starts injecting sealant
and air into the tire.
8. When the sealant injection is complete,
continue to add air.
9. After the air pressure reaches front: 35 psi
(240 kPa)/rear: 33 psi (230 kPa), turn off
the kit.
u To check the pressure, occasionally turn
off the compressor and read the gauge.
10. Unplug the power plug from the accessory
power socket.
11. Unscrew the sealant/ai r hose from the tire
valve stem. Reinstall the valve cap.
12. Press the pressure relief button until the
gauge returns to 0 psi (0 kPa).Pressure Gauge

1Injecting Sealant and Air
If the required air pressure is not reached within 15
minutes, the tire may be too severely damaged for
the kit to provide the necessa ry seal and your vehicle
will need to be towed.
See an Acura dealer for a replacement sealant bottle
and proper disposal of an empty bottle.

4. Recheck the air pressure using the air only
hose on the compressor.
5. Turn the selector switch to AIR ONLY.
u Do not turn the air compressor on to
check the pressure.

6.If the air pressure is
• Less than 19 psi (130 kPa):
Do not add air or continue driving. The leak
is too severe. Call for help and have your
vehicle towed.
2 Emergency Towing P. 429
•Front: 35 psi (240 kPa) /rear: 33 psi (230
kPa) or more:
Continue driving for another 10 minutes or
until you reach the nearest service station.
Do not exceed 50 mph (80 km/h).
u If the air pressure does not go down after
10 minutes of driving, you do not need
to check the pressure any more.

• Greater than 19 psi (130 kPa), but less
than front: 35 psi (240 kPa)/rear: 33 psi

Turn the air compressor on to inflate the
tire until the tire pressure reaches front: 35
psi (240 kPa)/rear: 33 psi (230 kPa).
2 Inflating an Under-inflated Tire P. 411
Then drive carefully for 10 more minutes or
until you reach the nearest service station.
Do not exceed 50 mph (80 km/h).
u You should repeat this procedure as long
as the air pressure is within this range.
7. Press the pressure relief button until the
gauge returns to 0 psi (0 kPa).
8. Repackage and properly stow the kit.
