The maximum permissible distanc
ewhich
can be driven in run-flat mode is counted
from the moment the tyre pressure loss
warning appears in the multifunction dis-
play.
You must not exceed amaximum speed of
80 km/h. G
Risk of accident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when acceleratin grapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration ,aswell as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distanc ethat can
be driven in run-flat mode depends to alarge
exten tonthe loads placed on the vehicle. It
can be shorter due to high speeds, aheavy
load, sudden acceleration and/or manoeu-
vring, the road surface condition, outside tem-
perature, etc.,orf urther,ifyou drive carefully
and conservatively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle start stoshake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tyre.
After driving in run-flat mode, you must have
the wheel(s) checked for damage at aquali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the work required. The faulty tyre must be
replaced in every case.
Mercedes-Benz recommends that you use a
Mercedes-Benz Servic eCentre for this pur-
pose. In particular, work relevant to safety or on safety-related systems must be carried out
at
aq ualified specialist workshop.
Vehicles with MOExtended tyres*: when
replacing one or all tyres, make sure that you
only use tyres marked MOExtended and of
the specified size for the vehicle. Battery
Notes on the vehicle battery
In order for the battery to achieve the maxi-
mum possible service life, it must alway sbe
sufficiently charged.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standin gidle for a
lengthy period.
To prevent damage from corrosion, only
replace the battery with one that has acentral
ventilation cover.
Consult aMercedes-Benz Servic eCentre if
you wish to leave your vehicle parked up for
al ong period of time. G
Risk of injury
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion
Fire, naked flames and
smokin
gare prohibited
when handling the battery.
Avoid creatin gsparks. Battery acid is caustic.
Avoid contact with the skin,
eyes or clothing.
Wear suitable protective
clothing, in particular
gloves, an apron and
aface

environmentally responsible manner .Take
them to aMercedes-Ben zServic eCentre or
to as pecial collection poin tfor old batteries. G
Risk of injury
For safet yreasons ,Mercedes-Ben zrecom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increase dimpac tprotection to prevent vehi-
cle occupant sfroms ufferin gacid burns
should th ebattery be damaged in th eevent
of an accident.
To prevent acid burns, observe th efollowing
safet ynotes when handling batteries:
R do not lean over th ebattery.
R do not place any metal object sonabattery.
Otherwise, you could cause ashor tcircuit
and th ebattery's gas mixtur ecould ignite.
R mak esure that you do not create an elec-
trostatic charge, e.g .bywearingsynthetic
clothin gorasar esult of frictio nonfabrics.
Therefore, you should not pull or slide the
battery over carpet sorother synthetic
materials. R
never touc hthe battery first. To discharge
ap ossible electrostatic charge, step out of
th ev ehicle firs tand touc hthe bodywork.
R do not wipe th ebattery using acloth. The
battery may explode as aresult of electro-
static charge or due to flyin gsparks.
! Before loosening th eterminal clamps of
th eb attery, switch off th eengine and
remove th ekey or, on vehicles with KEY-
LESS-GO*, mak esure that th eignitio nis
not switche don. In th einstrumen tcluster,
all of th eindicator lamps must be out. Oth-
erwise ,you may destroy electronic compo-
nents ,such as th ealternator.

have work involvin gthe battery, e.g.
removal, charging and replacement, car-
ried out at aqualified specialist workshop,
e.g .aM ercedes-Ben zServic eCentre.
Installation location of th ebattery Your vehicle is equipped with
