Problems with the rear window defroster
Problem
Possible causes/consequences and
0050
0050Solutions The rear window
defroster has deacti-
vated prematurely or
cannot be activated. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window
defroster can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can deactivate the flow of fresh air if
unpleasant odors are enteringt
he vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.

Alwaysm ake sure that the engine speed
does not reach the red area of the tachom- eter and observe the upshift indicator.
There is otherwise arisk of engine damage.
X To activate the manual drive program:

Upshift indicator The upshift indicator is
afour-stage display
designed to assist you in sporty driving. The upshift indicator allows you to recognize
the ideals hift point for dynamic acceleration.
White segments 0043and yellow segment 0044
light up in succession from left to right.
When red segments 0087light up and the "up"
message appears in the multifunction dis-
play,t he ideals hift point has been reached:
X Shift up using the right-hand steering wheel
paddles hifter (UP) as quickly as possible.
The vehicle shifts up to the next gear. i
If you continue to increase the engine
speed without shifting up in time, the fuel
supplyiss hut off to protect the engine. This
results in abruptly reduced acceleration.
Display for downshift override You cannot shift down with the left steering
wheel paddles hifter if the engine speed is too
high due to adownshift. If you then pull the

General notes G
WARNING
If you leave children unsupervised in the vehi- cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is arisk of
an accident and injury.
When leaving the vehicle, alway stake the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there is amalfunction
in the system, it may not be possible to apply
the released parking brake.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it roll- ing away.
X Shift the automatic transmission to posi-
tion P.
It may not be possible to release an applied
parking brake, if the on-board voltage is low
or there is amalfunction in the system. Con-

Wet roads
If you have drive
nfor along time in heavy rain
without braking, there may be adelayed reac-
tion from the brakes whe nbraking for the first
time. This may also occur after the vehicl ehas
been washed or drive nthroug hdeep water.
You have to depress the brake pedal more
firmly .Maintain agreater distance from the
vehicl einfront.
After driving on awet road or having the vehi-
cle washed ,brake firmly while paying atten-
tion to the traffic conditions. This wil lwarmup
the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt-
treated roads If you drive on salted roads,
alayer of salt
residue may form on the brake discs and
brake pads. This can result in asignificantly
longe rbraking distance.
R Brake occasionally to remove any possible
sal tresidue. Make sure that you do not
endange rother road users whe ndoing so.
R Carefully depress the brake pedal and the
beginning and end of ajourney.
R Maintain agreater distance to the vehicle
ahead.
Servicing the brakes !
If the red brake warning lamp lights up in
the instrument cluster and you hea rawarn-
ing tone while the engine is running, the
brake fluid leve lmay be too low .Observe
additiona lwarning messages in the multi-
function display.
The brake fluid leve lmay be too low due to
brake pad wea rorleaking brake lines.
Have the brake syste mchecked immedi-
ately. This work should be carrie dout at a
qualified specialist workshop. !
As the ESP ®
syste moperates automati-
cally, the engine and the ignition must be
switched off (the SmartKey must be in posi-
tion 0or 1in the ignition lock or the Start/
Stop button must be in position 0or 1)i f:
R the electric parking brake is tested using
ab rake dynamometer.
R the vehicl eistowed with one axle raised.
Braking triggered automatically by ESP ®
may seriousl ydamage the brake system.
All checks and maintenance work on the
brake syste mmust be carrie dout at aquali-
fied specialist workshop. Have this work car- ried out at an authorized Mercedes-Benz
Center.
Have the brake pad sreplaced and the brake
fluid renewe dataqualified specialist work-
shop, e.g. an authorized Mercedes-Benz
Center.
If the brake syste mhas only been subject to
moderate loads, you should test the function- ality of you rbrakes at regulari ntervals. At a
high speed, brake firmly while paying atten-
tion to the traffic conditions. This improves
the grip of the brake pads.
You can find adescription of Brake Assist
(BAS) on (Y page55).
Mercedes-Benz recommends that you only
have brake pads/linings installed on your
vehicl ewhich have been approved for
Mercedes-Benz vehicles or which correspond to an equivalent quality standard. Brake
pads/linings which have not been approved
for Mercedes-Benz vehicles or which are not
