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 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 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 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 manoeu-
vring, the road surface condition, outside tem-
perature, 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 quali-
fied specialist workshop which has the nec-
essary 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 pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
Vehicles with MOExtended tyres*: if you
change one or all of the tyres, make sure that
you only use tyres marked MOExtended of the
specified size for the vehicle.
Battery
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 pro-
tective measures when handling batteries.
Risk of explosion
Fire, naked flames and
smoking are prohibited
when handling the battery.
Avoid creating sparks.
