Tyre pressure loss warning system
General notes
While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appear in the multifunction dis-
play.
You can recognise the tyre pressure loss
warning by the Run Flat Indicator Run Flat Indicator
active Restart with OK active Restart with OK message which
appears in the Serv Serv menu of the multifunc-
tion display. Information on the message dis-
play can be found in the "Restarting the tyre
pressure loss warning system" section
(
Y
page 448).
Important safety notes
The tyre pressure warning system does not
warn you of an incorrectly set tyre pressure.
Observe the notes on the recommended tyre
pressure (
Y
page 443).
The tyre pressure loss warning does not
replace the need to regularly check the tyre
pressures. An even loss of pressure on sev-
eral tyres at the same time cannot be detec-
ted by the tyre pressure loss warning system.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R
snow chains are fitted to your vehicle's
tyres.
R
road conditions are wintry.
R
you are driving on sand or gravel.
R
you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R
you are towing a very heavy or large trailer.
R
you are driving with a heavy load (in the
vehicle or on the roof).
Restarting the tyre pressure loss warn-
ing system
Restart the tyre pressure loss warning system
if you have:
R
changed the tyre pressure
R
changed the wheels or tyres
R
fitted new wheels or tyres
X
Before restarting, make sure that the tyre
pressures are set properly on all four tyres
for the respective operating conditions.
The recommended tyre pressures can be
found in the table on the fuel filler flap.
