Problems with the rear window heating
Problem
Possible causes/consequences and
M
MSolutions The rear window heat-
ing has switched off
prematurely or cannot
be activated. The battery has not been sufficiently charged.
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 heat-
ing can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can also temporarily deactivate the flow
of fresh air manually if unpleasant odours are
entering the vehicle from outside. The air
already inside the vehicle will then be recir-
culated.
If you switch on air-recirculation mode, the
windows can mist up more quickly, in partic-
ular at low temperatures. Only use air-recir-
culation mode briefly to prevent the windows misting up.
Activating/deactivating X
Turn the key to position 2in the ignition
lock (Y page 159).
X To activate: press thegrocker switch

Electric parking brake
General notes G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended 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 if there is a malfunc-
tion 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 from
rolling 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
if there is a malfunction in the system. Con-
tact a qualified specialist workshop.
The electric parking brake carries out a func-
tion check at regular intervals when the
engine is switched off. Noises that occur are
normal. Applying/releasing manually X
To apply: push handle :.
When the electric parking brake is applied, the red !indicator lamp lights up in the
instrument cluster.
The electric parking brake can also be
applied when the key is removed.
X To release: pull handle:.
The red !indicator lamp in the instru-
ment cluster goes out.
The electric parking brake can only be
released:
R when the key is in position 1or 2in the
ignition lock (Y page 159) or
R if the ignition was switched on using the
Start/Stop button
Applying automatically The electric parking brake is engaged auto-
matically if:
R DISTRONIC PLUS brings the vehicle to a
standstill or
R the HOLD function is keeping the vehicle
stationary
R Active Parking Assist is holding the vehicle
at a standstill
In addition, at least one of the following con-
ditions must be fulfilled:
R the engine is switched off
R the driver's door is open and the seat belt is
not fastened
R there is a system malfunction 180

the power supply is insufficient
R the vehicle is stationary for a lengthy period
The red !indicator lamp in the instrument
cluster lights up.
The electric parking brake is not automati-
cally applied if the engine is switched off by
the ECO start/stop function.
Releasing automatically The electric parking brake is released auto-
matically when all of the following conditions
are fulfilled:
R the engine is running
R the transmission is in position Dor R.
R the seat belt is fastened
R you depress the accelerator pedal
If the automatic transmission is in position R,
the boot lid must be closed.
If your seat belt is not fastened, the following conditions must be fulfilled to automatically
release the electric parking brake:
R the driver's door is closed
R you have shifted out of transmission posi-
tion Por you have previously driven faster
than 3 km/h.
Ensure that you do not depress the acceler-
ator pedal unintentionally. Otherwise, the
parking brake will be released and the vehicle will start to move.
Emergency braking The vehicle can also be braked during an
emergency by using the electric parking
brake.
X While driving, push handle :of the elec-
trical parking brake (Y page 180).
The vehicle is braked as long as you keep
handle :of the electric parking brake
pressed. The longer electric parking brake
handle :is depressed, the greater the brak-
ing force. During braking:
R a warning tone sounds
R the Release parking brake
Release parking brake message
appears
R the red !indicator lamp in the instru-
ment cluster flashes
When the vehicle has been braked to a stand- still, the electric parking brake is applied. Parking up the vehicle
If you leave the vehicle parked up for longer
than four weeks, the battery may be damaged by exhaustive discharging and further dam-
aged in the event of this occurring again.
X Disconnect the battery or connect it to a
trickle charger.
i You can obtain information about trickle
chargers from a qualified specialist work-
shop.
If you leave the vehicle parked up for longer
than six weeks, it may suffer from lack of use.
X Visit a qualified specialist workshop and
seek advice. Driving tips

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.

hands off the steering wheel for a prolonged
period of time, the system will first alert you
with a visual warning. A steering wheel sym-
bol appears in the multifunction display. If you have still not started to steer and have not
taken hold of the steering wheel after five
seconds at the latest, a warning tone also
sounds to remind you to take control of the

General notes AIRMATIC is an air suspension system with
variable damping for improved driving com-
fort. All-round level control ensures the best
possible suspension and constant ground
clearance, even with a laden vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption. There is also the
option to manually adjust the vehicle level.
AIRMATIC consists of level setting, level con-
trol and the Adaptive Damping System ADS
