WARNING
Driving when your engine is overheated can cause some fluids which may have leaked into
the engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening
the engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle until the engine has cooled down.
! Among other possible causes, the poly-V-belt could be broken. Do not continue to
drive.
Otherwise, the engine will overheat due to an inoperative water pump which may
result in damage to the engine. 170

Press I on electric air pump switch C.
The
electric air pump is switched on and
inflates the tire.
i First, the sealant is pumped into the

to

a high value. This is normal and not an
indication of a malfunction. Do not
switch off the electric air pump.
X Let the electric air pump inflate the tire
for a maximum of ten minutes.
Pressure gauge ; must display at least
180 kPa (1.8 bar, 26 psi)

.!
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.
X If a tire inflation pressure of at least
180 kPa (1.8 bar, 26 psi)

is not attained,
turn off the electric air pump by
pressing 0 on electric air pump switch
C.
X Unscrew the end of filler hose ? from
tire valve G.
X After clearing the area around the
vehicle of people and obstacles, drive

This

serves to better distribute the tire
sealant material inside the tire.
X Screw the end of filler hose ? onto tire
valve G.
X Inflate the tire again. G
WARNING
If a tire inflation pressure of
180
kPa (1.8 bar, 26 psi) 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
assistance or call Roadside Assistance.
X After attaining a tire inflation pressure
of

at least 180 kPa (1.8 bar, 26 psi), press
0 on electric air pump switch C.
The electric air pump is switched off.
X Turn the key in the starter switch to
position 0.

every 4 years. Replacement containers
are available at any authorized smart
center. G
WARNING
After changing a tire, contact a smart
center to make sure the bolts holding the
wheel to the car are tight enough.
Otherwise, the wheels could come off. Each
bolt should be tightened to a torque of
81 lb‑ft (110 Nm). Sealing a tire (Version 2)
