10 kPa (0.1 bar/1.5 psi) per 10 †. Take this
into account when checking the pressure of
warm tyres. Only correct the tyre pressure if
it is too low for the current operating condi-
tions.
Driving with tyre pressure that is too high or
too low can:
shorten the service life of the tyres
R
cause increased tyre damage
R
have a negative effect on handling charac-
R
teristics and thus the driving safety (e.g.
aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle.
Speeds up to 210 km/h: despite the values
stated on the tyre pressure information label
(fuel filler flap), for speeds up to
210 km/hand with 16" or 17" tyres, the val-
ues stated can be reduced as follows, without
a reduction in safety:
Saloon:Ò30 kPa (Ò0.3 bar/Ò4 psi)
R
Estate:Ò20 kPa (Ò0.2 bar/Ò3 psi)

This does not apply to vehicles towing a
trailer.
This improves the ride comfort of your vehi-
cle; however, fuel consumption may increase
slightly.
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
Run Flat Indicator
warning by the
active Restart with OK
Service
appears in the
function display. Information on the message
display can be found in the "Restarting the
tyre pressure loss warning system" section
( Y page 410).
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 407).
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:
snow chains are fitted to your vehicle's
R
tyres.
road conditions are wintry.
R
you are driving on sand or gravel.
R
you adopt a very sporty driving style (cor-
R
nering at high speeds or driving with high
rates of acceleration).
you are towing a very heavy or large trailer.
R
you are driving with a heavy load (in the
R
vehicle or on the roof).
