The depth of water must not exceed the
value specified in the table. Not ethat the
possible fording depth is less in flowing
water.
R Establish how deep the water is and the
characteristic softhe body of water before
fording.
R Select the highest possible vehicle level.
R Restrict the shift range to 1or 2.
R Avoid high engin espeeds.
R Enter and exit the water at aflat place and
at as teady walking pace.
! Under no circumstances should you
accelerate before entering the water. The
bow wave could cause water to enter and
damage the engine and neighbouring
assemblies.
R Drive slowl yand at aconstant speed
through the water.
R Do not stop.
! Do not open any of the vehicle' sdoors
while fording. Otherwise, wate rcould get
int ot he vehicle interior and damage the
vehicle' selectronics and interior equip-
ment.
R Water offer sahigh degree of resistance,
and the ground is slippery and in some
cases unstable. Therefore, it is difficult and
dangerous to pull away in the water.
R Ensure that abow wav edoes not for mas

R Clea nany mud from the tyre tread after
fording.
R Appl ythe brakes to dry them after fording. Winter driving
Genera lnotes G
WARNING
If the vehicle becomes trapped in snow,
ensure that snow is kept away from the
exhaust pipe and from around the vehicle as long as the engine is running. Otherwise, poi-
sonous carbon monoxide (CO) may enter the
vehicle, resulting in loss of consciousness and
even death.
To assure sufficient fresh air ventilation, open
aw indow slightly on the side of the vehicle
not facin gthe wind.
At the onset of winter, have your vehicle win-
terproofed at aqualified special istworkshop,
e.g. at aMercedes-Ben zService Centre.
Vehicles with the ON&OFFROAD package: if
driving in snow or with snow chains, select
the snow program (Y page 219) with the off-
road program selector wheel in the centre
console.
Driving with summer tyres Observ
ethe notes in the "Winter operation"
section (Y page 357).
Slippery roa dsurfaces G
WARNING
Do not shift down for additiona lengine brak-
ing on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.

X Depending on the size of the wheel, you
ma yalso be able to secure the faulty wheel
in the emergenc yspare wheel well. In this
case, you must remove the stowage tray
from the emergency spare wheel well and
store it securely in the luggage compart-
ment.
i When you are driving with the collapsible
emergency spare wheel fitted, the tyre
pressur eloss warnin gsystem or the tyre
pressure monitor cannot function reliably.
Only restart the tyre pressure los swarning
system/tyre pressure monitor when the
defective wheel has been replaced with a
new wheel.
Vehicles with tyre pressure monitor: all fit-
ted wheels must be equipped with func-
tioning sensors. The defective wheel
should no longer be in the vehicle. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allow you to continue driving the
vehicle even when one or more tyres lose all
air pressure.
MOExtended tyres may only be used in con-
junction with the activated tyre pressure loss
warning system or with the tyre pressure
monitor.
The maximum permissible distance which
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyre pressure loss warning
appears in the multifunction displ ay.
Yo um ust not exceed amaximum spee dof
80 km/h. G
WARNING
Th eh andling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well 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 distance that 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 changes in direction, the road
surface condition, outside temperature, etc.,
or further if you driv ecarefully and conserva-
tively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle starts to shake.
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 knowledg eand tool stocarry
out the work required. The faulty tyre must be
replaced in every case.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular ,work relevant to safet yor
on safety-related system smust be carried out
at aq ualified specialist workshop.
i Whe nreplacing one or all tyres, make
sure that you only use tyres marked
MOExtended and of the specified size for
the vehicle.
i Vehicles with MOExtended tyres are not
equipped with aTIREFIT kit at th efactory. 342

Tyre tread

WARNING
Bea rinm ind that:
R tyre gri pdecrease srapidly on wetroads
when the tread depth is less than 3mm.
Thus ,you should repl acet yres that have
insufficient tread.
R winter tyres sho uld bereplaced when the
trea ddepth is 4mmorl ess as they no lon-
ger provide adequat egrip.
R thet rea donat yre may not wear evenly.
Thus ,you should regularly chec kthe tread
depth and the condition of the tread across
the entire widt hofall tyres. If necessary,
turn the fron twheels to full lock in order to
inspec tthe tyr etrea dm ore easily.
Otherwise, you coul dlose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Note
sons electing, fitting and replac-
ing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fittin gnew tyres, run them in at mod-
erat espeeds for the first 10 0km, as they
onl yreach their ful lperformanc eafter this
distance.
R Do not drive wit htyres which have too little
tread depth ,asthis significantly reduces
the traction on wet roads (aquaplaning).
R Replace the tyres after six year satthe lat-
est, regardless of wear .This also applies to
the emergency spar ewheel/spar ewheel. MOExtended ty
res( tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allo wyou to continue drivin gthe vehicle even when one or mor

MOExtended tyres may only be used in con-
junction with the tyre pressure loss warning
system or with the tyre pressure monitor and
on wheels specifically tested by Mercedes-
Benz.
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 the TIREFIT
kit if you fit tyres that do not feature run-
flat properties, e.g. winter tyres. ATIREFIT
kit can be obtaine dfrom aMercedes-Benz
Ser vice Centre.
Notes on driving with MOExtended tyres in
the event of aflat tyre can be found in the
"Breakdown assistance" section
(Y page 342). Winter operation
Points to remember
At the onset of winter ,have your vehicle win-
terproofed at aqualified specialist workshop,

Observe the notes in the "Changin gawheel"
section (Y page 363). Drivin
gwith summer ty res
At temperatures below +7 †, summer tyres
los ee lasticit yand therefore traction and
