tyre pressure MERCEDES-BENZ M-CLASS SUV 2011 Owner's Guide

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
Tyre pressure .
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
displaye
dafter afew minutes of driving message appe
ars.
After ateach-in period, the tyr epressure
monito rautomatically recognise snew
wheels or new sensors. As long as aclear
allocation of the tyre pressure values to the individual wheels is not possible
,the Tyre pressure monito
ractive displa
ymes-
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
th et yrep ressure warning lamp ligh tsup in
the instrumen tcluster.
Eac htyret hat is affected by asignificant loss
of pressure is highlighted in th epressure dis-
play.
If the Please correc ttyrep ressure messag
eappear sinthe multifunctio ndis-
play:
X Chec kthe tyr epressure on all fou rwheels
and correc titifn ecessary.
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
tyre pressure monitor will automatically 362

have changed th etyrep ressure.

If you wis htodefinethe new reference values
manually:
X Use the tabl eonthe insid eofthe fuel filler

correctly in all four tyres for the current
operating conditions.
Also observe the notes in the section on
tyre pressures (Y page359).
X Make sure tha tthe key is in position 2in
the ignition lock.
X Press the =or; button on the steer-
ing wheel to selec tthe Service menu.
X Press the 9or: button to select

X Press the abutton.
The multifunction display shows the cur-
ren ttyre pressure of the individual tyres or
the Tyrepressures will be dis‐ played after a few minutes of driv‐
ing message.
X Press the :button.
The Usec urrent pressures as new reference values message appears in
th em ultifunction display.
If you wish to confirm the restart:
X Press the abutton.
The Tyre press. monito rrestarted message appears in th
emultifunction dis-
play.
After you have driven for afew minutes, the
system checks whether the curren ttyre
pressures are within the specified range.
The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
X Press the %button.
The tyre pressure values stored at the last
restart will continue to be monitored. Radio typ

aradio type approval for
the tyre pressure monitor may be required.

WARNING
Interchange th efront and rea rwheels only if
they hav ethe sam edimensions :for example
size, offset ,etc.
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.
The wear patterns on the fron tand rea rtyres

On vehicles that have the same size front and

! On vehicles fitted wit hatyre pressure
monitor, electronic components are loca-
ted in the wheel.
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.
Observe the tim erestric tion on use as well as
the speed limitation specified on the emer-
genc yspare wheel/spar ewheel. Storing wheels

otherwise be adv ersely affected. In addi-
tion, when driving with aload, tyr edimen-
sion variations could cause the tyres to

! 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).
i Notes on the vehicle equipment –always
fit the vehicle:

i Vehicles with MOExtended tyre sare not
equippe dwithaTIREFIT kit at th efactory.
It is therefore recommended that you addi-
tionally equip your vehicle with aTIREFIT kit
if yo ufit tyre sthat do not fea ture run-flat
