19. Stop at a safe location and check the tire pressure.
Refer to Steps 1 through 11 under “Using the Tire
Sealant and Compressor Kit without Sealant to
Inate a Tire (Not Punctured).”
If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended ination pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant cannot seal the tire.
SeeRoadside Assistance Program on page 7-7.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended ination
pressure, inate the tire to the recommended
ination pressure.
20. Wipe off any sealant from the wheel, tire, and
vehicle.
21. Dispose of the used sealant canister (E) and sealant/
air hose (F) assembly at a local dealer/retailer or in
accordance with local state codes and practices.
22. Replace it with a new canister available from your
dealer/retailer.
23. After temporarily sealing a tire using the tire sealant
and compressor kit, take the vehicle to an authorized
dealer/retailer within a 100 miles (161 km) of driving
to have the tire repaired or replaced.Using the Tire Sealant and Compressor

9. Press the on/off (B) button to turn the compressor on.
The compressor will inate the tire with air only.
10. Inate the tire to the recommended ination pressure
using the pressure gage (C). The recommended
ination pressure can be found on the Tire and
Loading Information label. SeeInflation - Tire
Pressure on page 5-60.
The pressure gage (C) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate reading.
The compressor may be turned on/off until the
correct pressure is reached.If you inate the tire higher than the recommended
pressure you can adjust the excess pressure by
pressing the pressure deation button (D), if
equipped, until the proper pressure reading is
reached. This option is only functional when using
the air only hose (G).
11. Press the on/off button (B) to turn the tire sealant
and compressor kit off.
Be careful while handling the tire sealant and
compressor kit as it could be warm after usage.

If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on the hazard
warning ashers. SeeHazard Warning Flashers
on page 3-6.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you or
other people. You and they could be badly injured
or even killed. Find a level place to change your
tire. To help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in P (Park).
3. If you have a four-wheel-drive vehicle, be
sure the transfer case is in a drive gear — not
in Neutral.

the tire farthest away from the one being
changed. That would be the tire on the other
side, at the opposite end of the vehicle.
When the vehicle has a at tire (B), use the following
example as a guide to assist you in the placement
of wheel blocks (A).
