WARNING
Th ejack is intended only for lifting the vehicle
briefly for wheel changes.
The vehicle must be placed on stands if you
intend to work under it.
Make sure that the jack is placed on afirm,

blocks or similar objects as ajack underlay.
The vehicle could otherwise slip off the jack
and seriousl yinjure you.
Do not start the engine at any time whil ethe
wheel is being changed.
Do not lie unde rthe vehicle when it is being
supported by the jack. If you do not raise the
vehicle as described, it coul dslip off the jack
(e.g. if the engine is started or adoor or the

injure you. G
WARNING
If you fai ltoposition the jac kcorrectly, the
vehicle may:
R slip off the jack
R injure you or others
R be damaged. Therefore, mak
esure that the jack is posi-
tioned correctly in the respective jacking
points. Before positioning the jack, remove
any dirt that may have collected in the jacking
points. Pleas enote that you must position the

Fitting anew wheel G
WARNING
Replac edamaged or corroded wheel bolts.
Never oil or grease wheel bolts. This could
cause the bolts to loosen in the wheel hub. G
WARNING
If aw heel hub thread is damaged, you must
not drive the vehicle any further. Consult a
qualified specialist workshop whic hhas the

WARNING
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea- 340

sons, Mercedes-Benz recommends that you
only use wheel bolts whic hhave been
approved for Mercedes-Benz vehicles and the
respective wheel. Other wheel bolts could
work loos eordamage the brake system.
Do not tighten the wheel bolts completely
while the vehicle is still jacked up. The vehicle
could topple off the jack. :

WARNING
Have the tightening torque checked immedi-
ately after awheel is changed. The wheels
coul dwork loose if they are not tightened to
at orqu eof150 Nm.
X Turn the jack back to its initia lposition and

change tool kit in the luggage compart-
ment.
Vehicles with an emergenc yspare wheel:
X Wrap the faulty wheel in the protec tive film

and transpor
tthe wheel in the luggage
compartment.
or
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
Flat tyreBreakdown assistance

It is therefore recommende
dthat you addi-
tionally equip your vehicle with aTIREFIT kit
if yo ufit tyres that do not featur erun-flat
properties, e.g. winter tyres. ATIREFIT kit
can be obtaine dfrom aMercedes-Benz
Ser vice Centre. Battery

WAR
NING
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
bee ntested and approved for your vehicle by
Mercedes-Benz .These batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering aci dburns
should the battery be damaged in the event
of an accident.
To prevent acid burns, observe the following
safety notes when handling batteries:
R do not lean over the battery.
R do not place any metal objects on abattery.
Otherwise ,you coul dcause ashort circuit
and the battery's gas mixtur ecould ignite. Battery

R
make sure that yo udonot create an elec-
trostati ccharge, e.g. by wearing synthetic
clothing or as aresul toff riction on fabrics.
Therefore, you should not pul lorslide the
battery over carpets or other synthetic
materials.
R never touc hthe battery fir st. To discharge
ap ossible electrostatic charge, ste pout of
the vehicle firs tand touch the bodywork.
R do not wipe the battery using acloth. The
battery may explode as aresul tofe lectro-
static charge or due to flying sparks.
! Switch off the engin eand remove the key
befo redisconnecting the terminal clamps
from the battery. On vehicles with KEY-
LESS-GO, mak esure that the ignition is
switched off .Check that all the indicator
lamps in the instrumen tcluster are off .You

nents, such as the alternator.
i When you park the vehicle, remove the
key if you do not require any electrical con-
sumers. The vehicle will then use ver ylittle
energy, thus conserving battery power.
Mercedes-Benz recom mends that you do not
carry out work on batteries yourself, e.g.
removing or charging. Have this work per-
formed at aqualified specialist workshop, e.g.
aM ercedes-Benz Servic eCentre. Installation location of the battery
