Risk of accident
If a wheel hub thread is damaged, you must
not drive the vehicle any further. Consult a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre or Service
24h for this purpose. In particular, work rel-
evant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop. G
Risk of accident
Only use wheel bolts that have been
designed for the wheel and the vehicle. For
safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts which
have been approved for Mercedes-Benz
vehicles. Other bolts could work loose.

Flat tyre
328 MOExtended run-flat system*
The MOExtended run-flat system must only
be used in conjunction with the tyre pressure
loss warning system or 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 50 km if the
vehicle is partially laden and 30 km if fully
laden.
The maximum range that can be driven in
emergency operation is measured from the
point at which the pressure loss warning
message appears in the multi-function dis-
play.
You must not exceed a maximum speed of
80 km/h.
i Vehicles featuring the MOExtended run-
flat system are not equipped with the
TIREFIT kit*.
It is therefore recommended to additionally
equip your vehicle with the TIREFIT kit*
when fitting tyres that do not feature run-
flat properties, e.g. winter tyres. i
A TIREFIT kit* is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre. 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 accelerating rapidly
Adapt your driving style accordingly and
avoid sudden changes in direction and sud-
den 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
a large extent on the loads placed on the
vehicle. It can be shorter due to high
speeds, a heavy load, sudden acceleration
and/or manoeuvring, the road surface con-
dition, outside temperature, etc., or further
if you drive carefully and conservatively.
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 rims checked for damage at a
qualified specialist workshop which has the
necessary 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 Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop.
i On a vehicle with MOExtended tyres, only
MOExtended spare tyres should be used.
These must be of the size specified for the
vehicle. Practical advice

Notes on the battery
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period.
To prevent damage from corrosion, only
replace the battery with one that has a central
ventilation cover.
Consult a Mercedes-Benz Service Centre if
you wish to leave your vehicle parked up for
a long period of time. G
Risk of injury
Comply with safety precautions and take
protective measures when handling batter-
ies. Risk of explosion
Fire, naked flames and
smoking are prohibited
when handling the bat-
tery. Avoid creating
sparks. Battery acid is caustic.
Avoid contact with the
skin, eyes or clothing.
Wear suitable protective
clothing, in particular
gloves, an apron and a
face mask.
Immediately rinse acid
splashes off with clean
water. Consult a doctor if
necessary.
Wear eye protection.
Keep children away.
Observe this Owner's
Manual.

Environmental note
Do not dispose of batteries with the house-
hold rubbish. Dispose of defective batteries
in an environmentally responsible manner.
Take them to a Mercedes-Benz Service Centre or a special collection point for old
batteries.
G
Risk of injury
Mercedes-Benz recommends that, for
safety reasons, you only use batteries
which have been tested and approved for
your vehicle by Mercedes-Benz. These bat-
teries provide increased impact protection
to prevent vehicle occupants from suffering
acid burns should the battery be damaged
in the event of an accident.
To prevent acid burns, observe the follow-
ing safety notes when handling batteries:
R Do not lean over batteries.
R Do not place any metal objects on a bat-
tery. You could otherwise cause a short
circuit and the battery's highly flammable
gas mixture could ignite.
R Make sure that you do not create an elec-
trostatic charge, e.g. by wearing syn-
thetic clothing or as a result of friction on
fabrics. Therefore, you should not pull or
slide the battery over carpets or other
synthetic materials.
R Never touch the battery first. To dis-
charge a possible electrostatic charge, Practical advice
