4 Tyre pressure loss warning system
G
Risk of accident
The tyre pressure loss warning system*
does not warn you of an incorrectly set tyre
pressure. The table on the inside of the fue l
filler flap will help you decide whether the
tyre pressures should be corrected.
The tyre pressure loss warning system*
does not replace the need to regularly
check your vehicle's tyre pressures, since
an even loss of pressure on several tyres at
the same time cannot be detected by the
tyre pressure loss warning system*.
The tyre pressure loss warning system* is
not able to warn you of a sudden loss of
pressure, e.g. following penetration by a
foreign object.
In the event of a sudden loss of pressure,
bring the vehicle to a halt by braking care-
fully. Do not make any sudden steering
movements when doing so.
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 spee d
of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning
message will appear in the multi-function dis-
play.
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 grave l
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 th e
vehicle or on the roof)
Restarting the tyre pressure loss warn-
ing system* Restart the tyre pressure loss warning sys-
tem* if you have
:
R changed the tyre pressure
R changed the wheels or tyre s
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler fla pto ensure that the tyre pressure in all fou
r
tyres is set correctly for the operating con-
ditions concerned .
X Also observe the notes in the section on
tyre pressures (Y page 213). G
Risk of accident
The tyre pressure loss warning system* can
only give reliable warnings if you have set
the correct tyre pressure.
If an incorrect tyre pressure is set, thes e
incorrect values will be monitored.
A tyre with insufficient pressure results in
an instability of the vehicle when driving,
thus increasing the risk of an accident .

G
Risk of accident
Interchange the front and rear wheels only
if they have the same dimensions, for exam-
ple size, offset, etc.
After every wheel interchange/change,
have the tightening torque checked at a
qualified specialist workshop that has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a tightening torque of
130 Nm.
For safety reasons, Mercedes-Benz recom -
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wheels may be interchanged every 5,000
km to 10,000 km depending on the degree of
tyre wear, provided that the vehicle has the
same size front and rear tyres. Do not reverse
the direction of tyre rotation. Operation
