Important safety notes If
at yre press urem onitor system is fitted, the
vehicle's wheels have sensor sfitted that
monitor the tyre pressures in all four tyres.
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 wil lhelp you
decide whether the tyre pressures should be
correc ted.
The tyr epressure monitor is not abl etow arn
you of asudden loss of pressure, e.g. if the Tyr

tyre is penetrated by
aforeign object .Inthe
event of asudden loss of pressure, bring the
vehicl etoah altbyb rakingcarefully. Do not
make any sudden steering movements when
doing so.
Informatio nontyre pressures is displayed in
the multifunction display. After afew minutes
of driv ing, the curren ttyre pressure of each
tyre is sho wn inthe multifunction display.
i Thet yre pressure values indicated by the
on-board computer may differ from those
measured at afilling station with apressure
gauge. Th etyre pressures shown by the on-
board computer refer to thos emeasured at
sea level. At high altitudes, the tyr epres-
sure values indicated by apressure gauge
are higher than thos eshown by the on-
boar dcomputer .Inthis case ,donot reduce
the tyr epressures.
i Theo peration of the tyr epressure moni-
to rc an 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 tyr epressure electronically X
Make sure that the key is in position 2
(Y page 139) in the ignitio nlock.
X Press the =or; button on the steer-
ing wheel to select the Serv. menu.
X Press the 9or: button to select

X Press the abutton.
The curren ttyre pressure for each wheel
will be displayed in the multifunction dis-
play.
If the vehicle has been parked for longe rthan
20 minutes, the Tyre pressures will be

After ateach-in period, the tyr epressure

allocation of the tyre pressure values to the individual wheels is not possible
,the Tyre pressure monito
ractive displa

sage is shown instead of the tyr epressure
display. Th etyre pressures are already being
monitored.
i Ifas pare wheel/emergenc yspare wheel
is fitted, the system may continue to show
the tyr epressure of th ewheel that has
been removed for afew 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/emergenc yspare
wheel's current tyr epressure.
Tyre pressure monito rwarning mes-
sages If the tyre pressure monitor detects
asignifi-
cant pressure loss on one or more tyres, a
warnin gmessage is shown in the multifunc-
tion display. Awarning ton ealso sounds and

i If the wheel positions on the vehicle are
inter changed, the tyre pressures may be
displ ayed for th ewrong positions for a
short time .This is rectified after afew
minutes of driving, and the tyr epressures
are displayed for th ecorrect positions.
Restarting th etyre pressure monitor When yo
urestar tthe tyr epressure monitor,
all existing warning message sare deleted and
th ew arning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
ence values for monitoring. In most cases, the

After every whee linterchange/change, have
the tightening torque checked at aqualified
specialist workshop that has the necessary
specialist knowledg eand tool stocarry out
the work required. Mercedes-Benz recom-
mends that you use aMercedes-Benz Service
Centr efor this purpose. In particular ,work
relevant to safet yoronsafety-related sys-
tems must be carried out at aqualified spe-
cialist workshop.
The wheel scould work loose if they are not
tightened to atorqu eof150 Nm.
For safety reasons, Mercedes- Benz recom-
mends that you only use wheel bolts of the
correct siz ewhich hav ebeen approved for
Mercedes-Ben zvehicles.

Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the tyres changed at aquali-
fied specialist workshop, e.g. aMercedes-
Benz Servic eCentre. Direction of rota
tion
Tyres with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit an emergenc yspare wheel/spare
wheel against the direction of rotation.

tain characteristics, e.g. handling, vehic le
nois eemis sions or fuel consumption, may
otherwise be adv ersely affected. In addi-
tion, when driving with aload, tyr edimen-
sion variations could cause the tyres to
come into contact with the bodywork and

! Retreaded tyres ar eneither tested nor
recommended by Mercedes-Benz, since
previous damage can nota lways be detec-
ted on retreaded tyres. As aresult,
Mercedes-Benz can notg uarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage.
! Large wheels: the lower the section width
for acertain wheel size, the lower the ride
comfor tisonp oor roadsurfaces. Roll com-
fort and suspensio ncomfort ar ereduced
and the risk of damage to the wheels and
tyres as aresult of driving over obstacles
increases.
i You will fin datable of tyre pressures on
the inside of your vehicle's fuel filler flap.
For further information on tyre pressure,
see (Y page 359).

zparts
Mercedes-Ben ztests genuin eparts 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 -Benz is
unabl etoe valuat eother parts. Mercedes-
Benz therefore 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 coun tries, 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 ma
yinvalidat ethe vehicle's
general operating permit. This is the case if:
R they cause achange of the vehicle type
from that for whic hthe vehicle' sgeneral
operating permit was granted.
R other road users could be endangered.
R the emission or noise levels are adversely
affected. G
WARNING
Drivin gsafety 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-Benz recommends
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.
