R there are tears in the sidewall softhe tyre.
After driving in emergency mode, have the
whee lrims checked at aquali fied specialist
workshop with regar dtotheir furthe ruse. The
fault ytyre must be replaced.
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is atotal loss of
pressure in one or mor etyres.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning syste morwith an activ etyre pres-
sure monitor.
The maximum driving distance is approx-
imately 80 km when the vehicle is partially
laden, and approximatel y30kmwhen the
vehicle is fully laden.
In addition to the vehicle load, the drivin gdis-
tance possible depends upon:
R speed
R road condition
R outside temperature
The drivin gdistance possible in run-flat mode
may be reduced by extrem edriving condi-
tions/manoeuvres ,oritcan be increased
through amoderate style of driving.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyr epressure loss warning
appe arsint he multifunction display.
You must not exceed amaximum spee dof
80 km/h.
i When replacing one or all tyres, make
sure tha tyou only use tyres marked
"MOExtended". Make sure that you only
use the size of tyr especified for the vehicle.
i Vehicles with MOExtended tyres are not
equipped with aTIREFIT kit at th efactory.
It is therefore recommended that you addi-
tionally equip your vehicle with aTIREFIT kit
if yo ufit tyres that do not featur erun-flat
characteristics, e.g. winter tyres. ATIREFIT kit can be obtaine
dfrom aqualified spe-
cialist workshop. TIREFIT kit
Usin gthe TIREFIT kit TIREFIT is
atyre seal ant.
You can use TIREFIT to seal punctures of up
to 4m m, particularl ythose in the tyr etread.
Yo uc an use TIREFI Tatoutside temperatures
down to Ò20 †. G
WARNING
In the following situations, the tyre sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tyre properly:
R there are cuts or punctures in the tyre
larger than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on aflat tyre.
There is arisk of accident.
Do not drive any further. Contact aqualified
specialist workshop. G
WARNING
The tyre sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not
inhale TIREFIT fumes. Keep tyre sealant away
from children. There is arisk of injury.
If you come into contact with the tyre sealant,
observe the following:
R Rinse off the tyre sealant from your skin
immediately with water.
R If the tyre sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tyre sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately. Flat tyre

Important safety notes
Work on the battery, e.g. removin gorinstal-
ling ,requires specialist knowledge and the
use of special tools. Therefore, always have
work on the batter ycarried out at aqualified
specialist workshop. G
WARNING
Work carried out incorrectly on the battery
can, for example, lead to ashort circui tand
damage your vehicle's electronic system. This
can disrupt driving safety systems such as ABS (anti-lock braking system) or ESP
®
(Elec-
tronic Stability Program).
R If ABS malfunctions ,the wheels can lock
during braking. This limits the steerability
of the vehicle when brakin gand the braking
distance may increase. There is arisk of
accident.
R If ESP ®
malfunctions, the vehicle will not be
stabilised if it start stoskid or awheel star ts
to spin. There is arisk of accident.
You should therefore have all work involving
the batter ycarried out at aqualified specialist
workshop. G
WARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of abattery. There is arisk of an
explosion.
Befor ehandling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-
starting.
Always make sure that neither you nor the
batter yiselectrostatically charged. There is
ab uild-up of electrostatic charge, e.g.:
R by wearing clothing made from synthetic
fibres
R due to friction betwee nclothin gand seats
R if you pus horpull the batter yacross the
carpe torother synthe ticm aterials
R if you wipe the batter ywithacloth. G
WARNING
Durin gthe charging process, abatter yprodu-
ces hydroge ngas. If ashort circui toccurs or
sparks are created, the hydroge ngas can
ignite. There is arisk of an explosion. 382

Information on driving
Check the tyre pressures when the vehicle is
heavily laden and, if necessary, adjust.
While driving, pay attention to vibrations,
noises and unusual handling charac teristics,
e.g .pulling to one side .This ma yindicate that
the wheels or tyres are damaged. If you sus-
pect that atyre is defective, reduce your
speed immediately. Stop the vehicle as soon
as possibl etocheckthe wheels and tyres for
damage. Hidden tyr edamage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tyres
and wheel schecked at aqualified specialist
workshop.
When parking your vehicle, make sure that
the tyres do not get deformed by the kerb or 396

hsummer tyres
At temperatures belo w+7† ,summer tyres
lose elasticity and therefore traction and
braking power. Change the tyres on your vehi-
cle to M+S tyres .Using summer tyres at very
cold temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility
for this typ eofdamage. M+S tyres
G
WARNING
M+S tyres with atyre tread depth of less than
4mma re not su itable for use in winter as they
do not provid esufficient traction. There is a
risk of accident.
M+S tyres with atrea ddepth of less than
4mmm ust be replaced.
At temperatures below +7 †, use winter tyres
or all-seas ontyres.B oth types of tyr eare
identified by th eM+S marking.
Onl ywinter tyres bearing the isnowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintr yroad con-
ditions.
Only these tyres will allow drivin gsafety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. Thes etyres have been devel-
ope dspecifically for driving in snow.
Use M+S tyres of the same mak eand tread
on all wheels to maintain safe handling char-
acteris tics.
Alway sobserv ethe maximum permissible

If you fit M+S tyres that have alower maxi-
mu mp ermissible speed than that of the vehi-
cle, affix acorresponding warnin glabel in the
driver' sfield of vision. This can be obtained
at aq ualified specialist workshop.
Under these circumstances, you should also

Snow chains
G
WARNING
If you hav efitted snow chains to the front
wheels, they may scrape against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tyres.
There is arisk of an accident.
To avoid hazardous situations:
R never fit snow chains on the fron twheels
R fit snow chains to the rea rwheels in pairs.
! You must driv eatraised vehicle level if
snow chains have been fitted. The vehicle
could otherwise be damaged. Observe the
information in the "AIRMATIC package"
section.
! Do not use the Adaptive Damping System
(ADS )sports mode if you have fit teds now
chains .The vehicle could otherwise be
damaged.
! On some tyr esizes there is not enough
space for snow chains. In order to prevent
damage to the vehicle or the tyres, observe
the "Tyre and wheel combinations" section
under "Tyres and wheels".
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz, or that are of acorre-
spondin gstandard of quality.
If you intend to fit snow chains ,please bear
the following points in mind:
R only use snow chains when the road sur-
face is completely snow-covered. Remove
the snow chains as soon as possible when
you come to aroad that is not snow- cov-
ered.
R do not exceed the maximu mpermissible
speed of 50 km /h. R
local regulations may restric tthe use of
snow chains. Observ ethe appropriate reg-
ulations if you wish to fit snow chains.
R snow chains cannot be fitted to all wheel-
tyr ec ombinations. Permissible wheel-tyre
combination s(Ypage 409).
i You may wish to deactivat eESP®
when
pull inga way with snow chains fitted
(Y page 67). This way you can allow the
wheels to spin in acontrolled manner ,ach-
ieving an increased driving force (cutting

WARNING
Tyres with too low or too high tyre pressure
