Stop afte rdriving for approximatel yten
minutes and check the tire pressure with
the tire inflation compressor.
The tire pressure mus tnow be at least
130 kPa (1.3 bar/19 psi). G
WARNING
If the required tire pressure is not reached
after driving for ashort period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving
characteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
X Correct the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi) (for the values,
see the Tire and Loading Information
placard on the driver's side B-pillar or tire
pressure table on the fuel filler flap).
X To increase the tire pressure: switch on
the tire inflation compressor. X
To reduce the tire pressure: depress
pressure release button 001Anext to
pressure gauge 0010. X
To remove the tire sealant bottle from the
tire inflation compressor ,press together
the lockin gtabs on the yellow cap.
X Pull the tire sealant bottle out of the tire
inflation compressor.
The filler hose remains attached to the tire
sealant bottle.
X Stow the tire sealant bottle and the tire
inflation compressor.
X Drive to the nearest qualified specialist
workshop and have the tire changed there.
X Have the tire sealant bottle and the filler
hose replaced as soon as possible at a
qualified specialist workshop.
X Have the tire sealant bottle replaced every
four years at aqualified specialist
workshop. Battery (vehicle)

oss warning system
General notes While the vehicle is in motion, the tire
pressure loss warning system monitors the
set tire pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in atire. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorresponding warning
message will appearint he multifunction
display.
You can recognizet he tire pressure loss
warning by the Run Flat Indicator Active Press 'OK' to Restart message
which appears in the Service menu of the
multifunction display. Further information on
the message displayc an be found under
"Restarting the tire pressure loss warning
system" (Y page 319). Important safety notes The tire pressure warning system does not
warn you of an incorrectly set tire pressure.
Observe the notes on the recommended tire
pressure (Y
page 315).
The tire pressure loss warning does not
replace the need to regularly check the tire
pressure. An even loss of pressure on several
tires at the same time cannot be detected by
the tire pressure loss warning system.
The tire pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tire is penetrated by aforeign object.Int he
event of asudden loss of pressure, bring the
vehicle to ahalt by braking carefully. Avoid
abrupt steering maneuvers.
The function of the tire pressure loss warning
system is limited or delayed if:
R snow chains are mounted on your vehicle's
tires.
R road conditionsa re wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style
(corneringath igh speeds or driving with
high rates of acceleration).
R you are driving with aheavy load (in the
vehicle or on the roof).
Restarting the tire pressurel oss
warning system Restart the tire pressure loss warning system
if you have:
R
changed the tire pressure
R changed the wheels or tires
R mounted new wheels or tires
X Before restarting, make sure that the tire
pressures are set properly on all four tires
for the respective operating conditions.
The recommended tire pressure can be
found on the Tire and Loading Information
placard on the B-pillar on the driver's side.
Additionally, atire pressure table is
