00BBPress on and off switch 3onthe tire infla‐
tion compressor.
The tire inflation compressor is switched on.
The tire is inflated. Fir st, tire sealant is pum‐
ped into the tire. The pressure may brief ly
ri se toappr oximately 500 kPa (5 bar/73 psi).
Do not switch off the tire inflation compres‐
sor du ring this phase.
00BBLet the tire inflation compressor runfo r a
maximum of ten minu tes.
The tire should then ha veattained a tire
pressure of at least 200 kPa (2.0 bar/
29 psi).
If tire sealant leaks out, make sure you clean the
af fected areas as quickly as possible. It is pref‐
erable touse clean water.
If yo uge t tire sealant on your clo thing, ha veit
cleaned as soon as possible with per chloroe thy‐
lene. If, af
terte n minutes, a tire pressure of
200 kPa (2.0 bar/29 psi) has not been ach‐
ie ve d:
00BBSwitch off the tire inflation compressor.
00BBUn scr ew thefilling hose from theva lve of the
defective tire.
Please no tethat tire sealant may leak out when
unscr ewing thefilling hose.
00BBVe ry slowly drive theve hicle forw ards or
re ve rse appr oximately 33 ft(10 m).
00BBPump up the tire again.
Af ter a maximum of ten minu testh e tire
pressure must be at least 200 kPa (2.0 bar/
29 psi).
0071 WARNING Risk of accident due tothe
specified tire pressure not being reached
If th e specified tire pressure is not reached
af te rth e specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this ins tance.

The system checks the tire pressure and the tire
te mp erature of the tires fitted totheve hicle by
means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires,
are automatically taught-in thefirs t time they are
driven.
The tire pressure and the tire temp erature
appear in the multifunction display
(
→page 202).
If th ere is a subs tantial pressure loss or if the
tire temp erature is excessive, a warning will be
given:

clus ter (→page 459).
It is the driver's responsibility toset the tire
pressure tothere commended cold tire pressure
suitable forth e operating situation. Set the tire
pressure for cold tires using a tire pressure
ga uge. Notethat the cor rect tire pressure forth e
cur rent operating situation must firs t be taught-
in to the tire pressure monitoring sy stem. In most cases,
the tire pressure monitoring sys‐
te m will auto matically update the new refere nce
