7.

Press the inflator switch to turn on the 
compressor.

u

The compressor starts injecting sealant 
and air into the tire.

u

When the sealant injection is complete, 
continue to add air.

8.

After the air pressure reaches 36 psi (250 
kPa), turn off the kit.

u

To check the pressure, occasionally turn 
off the compressor and read the gauge.

9.

Unplug the power plug from the accessory 
power socket.

10.

Unscrew the sealant/air hose from the tire 
valve stem. Reinstall the valve cap.

Press the pressure relief button until the 
gauge returns to 0 psi (0 kPa).

Pressure Gauge

Injecting Sealant and Air

Until the sealant injection is complete, the pressure 
shown on the pressure gauge will appear higher than 
actual. After the sealant injection is complete the 
pressure will drop and then begin to rise again as the 
tire is inflated with air. This is normal. To accurately 
measure the air pressure using the gauge, turn the air 
compressor off only after the sealant injection is 
complete.

If the required air pressure is not reached within 10 
minutes, the tire may be too severely damaged for 
the kit to provide the necessary 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.

Changing a Flat Tire

If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually 
to reduce speed. Then, stop in a safe place. Replace the flat tire with a compact 
spare tire. Go to a dealer as soon as possible to have the full-size tire repaired or 
replaced.

1.

Park the vehicle on firm, level, and non-slippery surface, and apply the parking 
brake.

Changing a Flat Tire

NOTICE

Do not use an unapproved puncture-repairing agent 
on a flat tire, as it can damage the tire pressure 
sensor.

NOTICE

Do not use the jack if it doesn’t work properly. Call 
your dealer or a professional towing service.

Follow compact spare precautions:
Periodically check the tire pressure of the compact 
spare. It should be set to the specified pressure. 
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm

2

)

When driving with the compact spare tire, keep the 
vehicle speed under 50 mph (80 km/h). Replace with 
a full-size tire as soon as possible.

The compact spare tire and wheel in your vehicle are 
specifically for this model. Do not use them with 
another vehicle. Do not use another type of compact 
spare tire or wheel with your vehicle.

Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of 
the full-size rear tires and replace it with the compact 
spare tire. Remove the flat front tire and replace it 
with the full-size tire that was removed from the rear. 
Mount the tire chains on the front tire.

How to Set Up the Jack

How to Set Up the Jack

Do not use the jack with people or luggage in the 
vehicle.

Use the jack provided in your vehicle.
Other jacks may not support the weight (“load”) or 
may not fit the jacking point.

The following instructions must be followed to use 
the jack safely:

•

Do not use while the power system is on.

•

Use only where the ground is firm and level.

•

Use only at the jacking points.

•

Do not get in the vehicle while using the jack.

•

Do not put anything on top of or underneath the 
jack.

WARNING

The vehicle can easily roll off the jack, 
seriously injuring anyone underneath.

Follow the directions for changing a tire 
exactly, and no person should place any 
portion of their body under a vehicle that is 
supported by a jack.
