differ from those of the standard wheels.
Your vehicle's handling characteristics will
change when a "Minispare" emergency
spare wheel* is fitted. Adapt your style of
driving accordingly.
The "Minispare" emergency spare wheel*
may only be used for a short time. Do not
exceed the maximum speed of 80 km/h
and do not deactivate ESP ®

260 Otherwise, the jack will not be able to ach-
ieve its load-bearing capacity due to the
restricted height.
Do not start the engine at any time while
the wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the tailgate is opened or closed) and you
could be seriously injured. G
Risk of accident
If you fail to position the jack correctly, the
vehicle may:
R slip off the jack
R injure you or others
R be damaged
Thus, it is important to make sure that the
jack is positioned correctly in the respec-
tive jacking points. Before positioning the
jack, remove any dirt that may have collec-
ted in the jacking points.
The jacking points for the jack are located
behind the wheel housings of the front wheels
and in front of the wheel housings of the rear
wheels. 1

i When you are driving with the "Minispare"
emergency spare wheel* fitted, the tyre
pressure loss warning system* cannot
function reliably. MOExtended run-flat system*
The MOExtended run-flat system may only be
used in conjunction with the tyre pressure
loss warning system.
! 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. 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 wheel(s) 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
use MOExtended spare tyres. These must
be of the size specified for the vehicle. Practical advice

Battery
263Battery
Notes on the vehicle 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 to a special collection point for
old batteries. G
Risk of injury
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which
have been tested and approved for your
vehicle by Mercedes-Benz. These batteries
provide increased impact protection to pre-
vent 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 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

Towing and tow-starting
268
When towing, observe the legal requirements
in all countries concerned.
! When towing, pull away slowly and with-
out jerking. If the tractive power is too high,
the vehicles could be damaged.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
For towing distances over 50 km, the entire
vehicle needs to be lifted up and transpor-
ted.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with AUTOTRONIC* must not be
tow-started.
R If the engine does not start, try jump-start-
ing it (Y page 266).
R If it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre. R
The selector lever must be in position N
when towing a vehicle with AUTO-
TRONIC*.
R If you are towing the vehicle over a consid-
erable distance, this must only be done
with the front axle raised.
R The ignition must be switched off if you are
towing the vehicle with the front/rear axle
raised. Intervention by ESP ®
could other-
wise damage the brake system.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
erwise:
-you cannot switch on the ignition
- you cannot move the selector lever
to N(on vehicles with AUTOTRONIC*)
- you have no support when braking
i Switch off the automatic locking feature
before the vehicle is towed (Y page 110).
You could otherwise be locked out when
pushing or towing the vehicle. Fitting the towing eye
