500 kPa (5 bar/73 psi).
Do not switch off the tyre inflation com-
pressor during this phase.
X Let the tyre inflation compressor run for a
maximum of ten minutes. The tyre should
then have reached a pressure of at least
200 kPa (2.0 bar/29 psi).
If a pressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten minutes, see "Tyre pres- sure reached" (Y page 344).
If a tyre pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten minutes, see "Tyre
pressure not reached" (Y page 344).
If tyre sealant leaks out, make sure you clean the affected area as quickly as possible. It is pref-
erable to use clear water.
If you get tyre sealant on your clothing, have it
cleaned as soon as possible with perchloroethy-
lene.
Tyre pressure not reached If a tyre pressure of 200 kPa (2.0 bar/29 psi) has
not been reached after ten minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tyre.
Tyre sealant may leak out when the filler hose
is unscrewed.

After a maximum of ten minutes, the tyre
pressure must be at least 200 kPa (2.0 bar/
29 psi). G
WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the tyre in this instance. Damaged tyres and a tyre
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.

WARNING
A tyre temporarily sealed with tyre sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed the specified maximum speed with a tyre that
has been repaired using tyre sealant.
The maximum permissible speed for a tyre
sealed with tyre sealant is 80 km/h. The upper
part of the TIREFIT sticker must be affixed to the
instrument cluster where it will be easily seen by
the driver.
If a tyre pressure of 200 kPa (2.0 bar/29 psi) has been reached after ten minutes:

WARNING
A discharged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
If the warning and indicator lamps do not light up on the instrument cluster when temperatures are low, it is probably because the discharged battery has frozen. In this case, you may neither jump-
start the vehicle nor charge the battery. The service life of a battery that has been thawed may be
reduced. The starting characteristics may be impaired, especially at low temperatures. Have the
thawed battery checked at a qualified specialist workshop.
All vehicles:
! Vehicles with a petrol engine:
avoid repeated and lengthy starting attempts. Otherwise, the
non-combusted fuel may damage the catalytic converter.
Do not use a rapid charging device to start the vehicle. If your vehicle's battery is discharged, the
engine can be jump-started from another vehicle or from a second battery using jump leads.
Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible, jump-
start the vehicle using a second battery or a jump-starting device.
R Vehicles with a petrol engine: jump-start the vehicle only when the engine and exhaust system
are cold.
R All vehicles except vehicles with a lithium-ion battery: do not start the engine if the battery
is frozen. Let the battery thaw first.
R Jump-starting may be performed only using batteries with a nominal voltage of 12 V.
R Use only jump leads that have a sufficient cross-section and insulated terminal clamps.
R If the battery is fully discharged, leave the battery that is being used to jump-start connected for
