300 VEHICLE CARE
Caution (Continued)
The tyre is too severely damaged
and the tyre sealant and
compressor kit cannot inflate the
tyre. Remove the power plug from
the accessory power outlet and
unscrew the inflating hose from the
tyre valve.
11. Press the on/off button (2) to
turn the tyre sealant and
compressor kit off.
The tyre is not sealed and will
continue to leak air until the
vehicle is driven and the sealant
is distributed in the tyre,
therefore, Steps 12 18 must be
done immediately after Step 11.
Be careful while handling the
tyre sealant and compressor kit
as it could be warm after usage.
12. Unplug the power plug (8) from
the accessory power outlet in the
vehicle.
13. Turn the sealant/air hose (6)
anticlockwise to remove it from
the tyre valve stem.
14. Replace the tyre valve stem cap.
15. Replace the sealant/air hose (6),
and the power plug (8) back in
their original location.
16. If the flat tyre was able to inflate
to the recommended inflation
pressure, remove the maximum
speed label from the sealant
canister (5) and place it in a
highly visible location. Do not
exceed the speed on this label
until the damaged tyre is
repaired or replaced.
17. Return the equipment to its
original storage location in the
vehicle.
18. Immediately drive the vehicle
8 km (5 mi) to distribute the
sealant in the tyre.
19. Stop at a safe location and check
the tyre pressure. Refer to
Steps 1 11 under Using the Tyre
Sealant and Compressor Kit
without Sealant to Inflate a Tyre
(Not Punctured).
If the tyre pressure has fallen
more than 68 kPa (10 psi) below
the recommended inflation
pressure, stop driving the vehicle.
The tyre is too severely damaged
and the tyre sealant cannot seal
the tyre.
If the tyre pressure has not
dropped more than 68 kPa
(10 psi) from the recommended
inflation pressure, inflate the
tyre to the recommended
inflation pressure.
20. Wipe off any sealant from the
wheel, tyre and vehicle.
