The tyre pressure monitor warns you when
the pressure drops in one or more of the
tyres. The tyre pressure monitor only func-
tions if the correct sensors are fitted to all
wheels. G
WARNING
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. The table
on the inside of the fuel filler flap will help you
decide whether the tyre pressures should be
corrected.
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. Do not
make any sudden steering movements when
doing so.
Information on tyre pressures is displayed in
the multifunction display .After a few minutes
of driving, the current tyre pressure of each
tyre is show ninthe multifunction display.
i The tyre pressure values indicated by the
on-board computer may differ from those
measured at a filling station with a pressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tyre pres-
sure values indicated by a pressure gauge
are higher than those shown by the on-
board computer. In this case, do not reduce
the tyre pressures.
i The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
Checking tyre pressure electronically X
Make sure that the key is in position 2
(Y page 153) in the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Service menu.X
Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The current tyre pressure for each wheel
will be displayed in the multifunction dis-
play.
If the vehicle has been parked for longer than
20 minutes, the Tyre pressures will be
displayed after a few minutes of
driving message appears.
After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the Tyre pressure monitor active display mes-
sage is shown instead of the tyre pressure
display. The tyre pressures are already being
monitored.
i If a spare wheel/emergency spare wheel
is fitted, the system may continue to show
the tyre pressure of the wheel that has
been removed for a few minutes. If this
occurs, note that the value displayed for
the position where the spare wheel/emer-
gency spare wheel is fitted is not the same
as the spare wheel/emergency spare
wheel's current tyre pressure.
Tyre pressure monitor warning mes-
sages If the tyre pressure monitor detects a signifi-
cant pressure loss on one or more tyres, a
warning message is shown in the multifunc-
tion display.
Awarning tone also sounds and
the tyre pressure warning lamp lights up in
the instrument cluster.
Each tyre that is affected by a significant loss
of pressure is highlighted in the pressure dis-
play.
If the Please correct tyre pressure message appears in the multifunction dis-
play:
X
Chec kthe tyre pressure on all four wheels
and correct it if necessary. 364

Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 28).Notes on the technical data
You can find technical data on the Internet at:
http://www.mercedes-benz.com
i The technical data was determined in
accordance with EC Directives. All data
applies to the vehicle's standard equip-
ment. Therefore, the data may differ for
vehicles with optional equipment. You can
obtain further information from a
Mercedes-Benz Service Centre. Genuine Mercedes-Benz parts
Mercedes-Ben ztests genuine parts and con-
version parts and accessories which have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benzis
unable to evaluate other parts. Mercedes-
Ben ztherefore accepts no responsibility for
the use of such parts in Mercedes-Ben zvehi-
cles, even if they have been independently or
officially approved.
In Germany and some other countries, certain
parts are only officially approved for installa-
tion or modification if they comply with legal
requirements. All genuine Mercedes-Benz
parts meet this requirement .The use of non- approved parts may invalidate the vehicle's
general operating permit. This is the case if:
R
they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted.
R other road users could be endangered.
R the emission or noise levels are adversely
affected. G
WARNING
Driving safety may be impaired if non-
approved parts, tyres and wheels or safety-
relevant accessories are used.
This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. This
could cause you to lose control of your vehicle
and cause an accident.
For this reason, Mercedes-Ben zrecommends
that you use genuine Mercedes-Benz parts or
parts of equal quality. Only use tyres, wheels
and accessories that have been specifically
approved for your vehicle.
! Airbags and seat belt tensioners, as well
as control units and sensors for these
restraint systems may be installed in the
following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have aftermarket accessories installed at
a qualified specialist workshop. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. 376

WARNING
Only have work on the engine electronics and
related components carried out at a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Ben zService
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop. Otherwise, the vehicle's
roadworthiness could be affected.
! Only have maintenance work on the
engine electronics and its associated parts,
such as control units, sensors and connec-
tor leads, carried out at a qualified special-
ist workshop, e.g. a Mercedes-Benz Service
