Battery - Mercedes-Benz R-Class Owner's Manual

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:
when cornering
R
when braking
R
when accelerating rapidly
R
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:
you hear banging noises
R
the vehicle starts to shake
R
you see smoke and smell rubber
R
®
R ESP is intervening constantly
there are tears in the sidewalls of the tyre
R
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
use MOExtended spare tyres. These must
be of the size specified for the vehicle.
Practical advice

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.
