Owner's Manual Vehicles with a navigation system: the vehicle is close to a radio
telescope facility and is therefore prohibited from transmitting any
radar signals. The radar sensor system has switched off automat-
ically (Y
page 398).
If DISTRONIC PLUS was activated, it is no longer available. A
warning tone also sounds.
If Active Blind Spot Assist was activated, it is no longer available.
The yellow 9indicator lamps also light up in the exterior mir-
rors.
BAS PLUS (Brake Assist PLUS) and PRE-SAFE ®
Brake are then also
unavailable.
X Drive on.
Once you have moved far enough away from the radio telescope,
the above functions are available again. Vehicles with Becker
®
MAP PILOT: if the Becker ®
MAP PILOT is
not connected, the radar sensor system is deactivated automati-
cally.
BAS PLUS, DISTRONIC PLUS, Active Blind Spot Assist and
PRE-SAFE ®

Problem Possible causes/consequences and
M Solutions
!
The yellow ABS warning
lamp is lit while the
engine is running. ABS (Anti-lock Brake System) has been deactivated due to a fault.
For this reason, BAS (Brake Assist), BAS PLUS, ESP ®
(Electronic
Stability Program), PRE-SAFE ®
,P RE-SAFE ®
Brake ,the HOLD func-
tion, hill start assist, the adaptive brake lights and ESP ®
trailer
stabilisation are also deactivated, for example.
ATTENTION ASSIST is deactivated.
G WARNING
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.
The steerability and braking characteristics may be severely affec-
ted. The braking distance in an emergency braking situation can
increase.
If ESP ®
is not operational, ESP ®
is unable to stabilise the vehicle.
The danger of skidding and having an accident increases.
X Observe the additional display messages in the multifunction
display.
X Drive on carefully.
X Visit a qualified specialist workshop.
If the ABS control unit is faulty, there is also a possibility that other
systems, such as the navigation system or the automatic trans-
mission, will not be available. Warning and indicator lamps in the instrument cluster

On vehicles with COMAND Online and a
navigation system, the clock is set auto-
matically.

WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, naked flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention. G
WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases
can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
! Only charge the battery using the jump-
start connection point.
The jump-starting connection point is in the
engine compartment (Y page 344).
If, at low temperatures, the indicator lamps/
warning lamps in the instrument cluster do
not light up, it is highly likely that the dis-
charged battery has frozen. In this case, you may neither charge the battery nor jump-start
the vehicle. The service life of a thawed-out
battery may be shorter. Starting characteris-
tics are particularly impaired at low tempera-
tures. Have the thawed-out battery checked
at a qualified specialist workshop.
Never charge a battery which is still fitted in
the vehicle unless a Mercedes-Benz approved
battery charger is being used.
Abattery
charge runit specially adapted for Mercedes-
Benz vehicles and tested and approved by
Mercedes-Benz is available as an accessory.
It permits the charging of the battery in its
installed position. Contact a Mercedes-Benz
Service Centre for informatio nand availabil-
ity .R ead the battery charger's operating
instructions before chargin gthe battery.
X Open the bonnet (Y page 320).
X Connect the battery charger to the positive
terminal and earth point in the same order
as when connecting the donor battery in
the jump-starting procedure
(Y page 344). Battery (vehicle)

Vehicles with
anavigation system: the radar sensor system is deactivated automatically
near radio telescope facilities. Adisplay message appears in the multifunction display to tell
you that the radar sensor system is being switched off (Y page 263).
The currently active systems are automatically deactivated:

If deactivation does not occur automatically, you must deactivate the radar sensor system
using the on-board computer (Y page 243).
Vehicles withou tnavigation and vehicles for Australia: you must deactivate the radar
sensor system using the on-board computer whe nyou are near a radio telescope facility
