The vehicle's battery is drained by use of
the electric air pump. You should therefore
keep the engine running
in the open air

while inflating the tire.
>PressI on electric air pump switch
7.
The electric air pump is switched on and
inflates the tire.
i
First, the sealant is pumped into the tire.
The pressure may briefly increase to a high
value. This is normal and not an indication of a
malfunction. Do not switch off the electric air
pump.>Let the electric air pump inflate the tire for
a maximum of ten minutes.
Pressure gauge
2 must display at least
26 psi (1.8 bar) is reached. The filler hose
can become hot during inflation.
Please exercise appropriate caution.
!
Do not operate the electric air pump
longer than ten minutes without interruption.
Otherwise it may overheat.
You may operate the electrical air pump again
after it has cooled off.
>If the tire inflation pressure of at least
26 psi (1.8 bar) is not attained, turn off the
electric air pump by pressing0 on electric
air pump switch
7.
>Unscrew the end of filler hose
4
from the
tire valve.
>After clearing the area around the vehicle
of people and obstacles, drive vehicle back
or forth very slowly approximately 30 ft
(10 m).
This serves to better distribute the tire
sealant material inside the tire.>Screw the end of filler hose
4 onto the tire
valve.
>Inflate the tire again.
>After attaining a tire inflation pressure of
26 psi (1.8 bar), press0 on electric air
pump switch
7.
The electric air pump is switched off.
>Turn the key in the starter switch to
position0.
G
Warning!
If a tire inflation pressure of 26 psi
(1.8 bar) is not attained, the tire is too
severely damaged for the tire sealant to
provide a reliable tire repair.
In this case, the tire sealant cannot
properly seal the tire.
Do not drive the vehicle.
Contact the nearest smart center for as

sistance or call Roadside Assistance.
