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 13–21 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 (9) from the accessory power outlet in the
vehicle.
14. Turn the sealant/air hose (2) counterclockwise to remove it from
the tire valve stem.
15. Replace the tire valve stem cap.
16. Remove the tire sealant canister (4) from the slot on top of the

17. Turn the air only hose (10) counterclockwise to remove it from
the tire sealant canister inlet
valve (1).
18. Turn the sealant/air hose (2) clockwise onto the sealant canister
inlet valve (1) to prevent sealant
leakage. 19. Return the air only hose (10) and
power plug (9) back to their
original storage location.
20. If the flat tire was able to inflate tothe 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–

temporary use only. The vehicle will
perform differently with the spare tire
installed and it is recommended that
the vehicle speed be limited to
80 km/h (50 mph). To conserve the
tread of the spare tire, have the
standard tire repaired or replaced as
soon as convenient and return the
spare tire to the storage area.
When using a compact spare tire, the
AWD (if equipped), ABS, and Traction
Control systems may engage until the
spare tire is recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible wheel slip.
