16. Replace the tire sealant canister inlet valve (1) cap.
17. Return the air only hose (8) and power plug (7) back to their original storage
location.
18. If the flat tire was able to inflate to therecommended 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.
19. Return the equipment to its original storage location in the vehicle.
20. Immediately drive the vehicle 8 km (5 mi) to distribute the sealant in
the tire. 21. Stop at a safe location and check the tire

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.
SeeRoadside Assistance Program 0399.
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.
22. Wipe off any sealant from the wheel, tire, or vehicle.
23. Dispose of the used tire sealant canister (3) at a local dealer or in
accordance with local state codes and
practices.

Full-Size Spare Tire
If this vehicle came with a full-size spare
tire, it was fully inflated when new,
however, it can lose air over time. Check the
inflation pressure regularly. See Tire Pressure
0 349 and
Vehicle Load Limits 0193 for information
regarding proper tire inflation and loading the vehicle. For instructions on how to
remove, install, or store a spare tire, see
Tire
Changing 0369.
After installing the spare tire on the vehicle,
stop as soon as possible and check that the
spare is correctly inflated. The spare tire is
made to perform well at speeds up to
112 km/h (70 MPH) at the recommended
inflation pressure, so you can finish
your trip.
Have the damaged or flat road tire repaired
or replaced and installed back onto the
vehicle as soon as possible so the spare tire
will be available in case it is needed again.
Do not mix tires and wheels of different
sizes, because they will not fit. Keep the
spare tire and its wheel together.
Caution
If the vehicle has four-wheel drive and a
different size spare tire is installed, do
not drive in four-wheel drive until the flat
tire is repaired and/or replaced. The
vehicle could be damaged and the repairs
would not be covered by the warranty.
Never use four-wheel drive when a
different size spare tire is installed on the
vehicle.
