Do not mix these fuels with diesel fuels and
do not use any special additives. Other-
wise, this can lead to damage to the engine.
This excludes flow improver ;see "Low out-
side temperatures".
! Use afilter when adding fuel from afuel
can. Otherwise, the fuel lines and/or the
diesel injection system could be blocked by
particles from the fuel can.
For further information on "Fuel", see
(Y page 374).
Low outsid etemperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
peratur eclasses are defined in EN 590 .Refu-
elling with diesel fuel which complies with the
climatic specification sofstandard EN 590
can hel ptoprevent operatin gproblems. At
exceptionall ylow tempera tures, it is possible
that the flow properties of the fuel ma ybe
inadequate. This also applies to fuel that has
not been adapted to suit the climatic condi-
tions, e.g. diesel fuel from warmer regions.
i Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g. at filling stations.
Flow improver Flow improvers can be added to improv
ethe
cold resistan ceof diesel fuel. The effective-
ness of aflow improver is not guaranteed with
every diesel fuel.
Correc tdosage and thorough mixing ar edeci-
sive factor sinensuring improvement in low-
temperature resistance. Avoid excessive dos-
age .Exce ssiv edosage ma yactuall ydecrease

wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using aflow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz

the wheels and replace them if necessary.
Checklist after driving off-road !
If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at aqualified specialist work-
shop.
Driving over rough terrain places greater
demands on your vehicle than driving on nor-
mal roads. After driving off-road, check the
vehicle. This allow syou to detec tdamage
promptly and reduce the risk of an accident
to yourself and other road users.
X Vehicles with the ON&OFFROAD pack-
age: activate the on-road program
(Y page 222).
X Vehicles without the ON&OFFROAD
package: deactivate the on-road program
(Y page 222).
X Deactivate the LOW RANGE off-road gear
(Y page 223).
X Deactivate DSR (Y page 220).
X Lower the vehicle level again to alevel suit-
able to the road conditions, e.g. to the high-
way/high-speed level.
X Clean the headlamps and rear lights and
check for damage.
X Clean the front and rear licence plates.
X Clean the wheels/tyres with awater jet and
remove any foreign objects.
X Clea nthe wheels, wheel arches and the
vehicle underside with awater jet; check
for any foreign objects and damage.
X Check whethe rtwigs or other parts of

i Only operate the tyre inflation compres-
sor using a12Vsocket (Y page 309), even
if the ignition is turned off.
An emergenc ycut-off ensures that the on-
board voltage does not drop too low. If the
on-board voltage is too low, the power to
the sockets is automatically cut. This
ensures that there is sufficient power to
start the engine. TIREFIT kit

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
G
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
etyres los eall
air pressure.
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,
e.g. at aMercedes-Ben zService Cent re.
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
braking power; chang ethe tyres on your vehi-
cle to M+S tyres .Using summer tyres at very
cold temperatures could cause tears to form,
thereby damagin gthe tyres permanently.
Mercedes-Ben zcannot accept responsibility
for this type of damage. Winter operation
