Electric parking brake
General notes
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart 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
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The function of the electric parking brake is
depending on the on-board voltage. If the on-
board voltage is low or there is a malfunction in
the system, it may not be possible to apply the
released parking brake.
XIf this happens, park the vehicle on level
ground only and secure it to prevent it from
rolling away.
XShift the transmission to position j.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is a malfunction in the system. Contact a
qualified specialist workshop.
The electric parking brake performs a function
test at regular intervals while the engine is
switched off. The sounds that can be heard while
this is occurring are normal.
Applying or releasing manually
XTo apply: push handle :.
When the electric parking brake is applied,
the red F(USA only) or !(Canada
only) indicator lamp lights up in the instru-
ment cluster.
The electric parking brake can also be applied
when the SmartKey is removed.
XTo release: pull handle:.
The red F(USA only) or !(Canada
only) indicator lamp in the instrument cluster goes out.
The electric parking brake can only be released:
Rif the SmartKey is in position 1or2 in the
ignition lock (Ypage 123) or
Rif the ignition was switched on using the
Start/Stop button
Applying automatically
The electric parking brake is automatically
applied when the transmission is in position j
and:
Rthe engine is switched off or
Rthe driver is not wearing a seat belt and the
driver's door is opened
To prevent the electric parking brake from being
automatically applied, pull handle :.
The electric parking brake is also engaged auto-
matically if:
RDistance Pilot DISTRONIC brings the vehicle
to a standstill or
Rthe HOLD function is keeping the vehicle sta- tionary
RParking Pilot is keeping the vehicle stationary
In addition, at least one of the following condi-
tions must be fulfilled:
Rthe engine is switched off
Rthe driver is not wearing a seat belt and the
driver's door is opened
Rthere is a system malfunction
Rthe power supply is insufficient
Rthe vehicle is stationary for a lengthy period

iCruise control is not deactivated if you
depress the accelerator pedal. If you acceler-
ate to overtake, cruise control adjusts the
vehicle's speed to the last speed stored after
you have finished overtaking.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol:
XBriefly press the cruise control lever forward
=.
or
XBrake.
Cruise control is automatically deactivated if:
Ryou engage the electric parking brake
Ryou are driving at less than 20 mph (30 km/h)
RESP®intervenes or you deactivate ESP®
Ryou shift the transmission to position i
while driving
If cruise control is deactivated, a warning tone
sounds. You will see the Cruise Control Off
message in the multifunction display for approx-
imately five seconds. The message on the mul-
tifunction display disappears and the segments
on the speedometer go out.
iWhen you switch off the engine, the last
speed stored is cleared.
Distance Pilot DISTRONIC
General notes
Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehicles
are detected with the aid of the radar sensor
system. Distance Pilot DISTRONIC brakes auto-
matically so that the set speed is not exceeded. Change into a lower gear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden. By doing so, you
will make use of the braking effect of the engine.
This relieves the load on the brake system and
prevents the brakes from overheating and wear-
ing too quickly.
If Distance Pilot DISTRONIC detects that there is a risk of a collision, you will be warned visually
and acoustically. Without your intervention, Dis-
tance Pilot DISTRONIC cannot prevent a colli-
sion. An intermittent warning tone will then
sound and the distance warning lamp will light
up in the instrument cluster. Brake immediately in order to increase the distance to the vehicle in
front or take evasive action provided it is safe to
do so.
Distance Pilot DISTRONIC operates in the range
between 0 mph (0 km/h) and 120 mph
(200 km/h).
Do not use Distance Pilot DISTRONIC whi
le driv-
ing on roads with steep gradients.
Since Distance Pilot DISTRONIC transmits radar
waves, it can resemble the radar detectors of
the responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.

AIRMATIC
General notes
AIRMATIC is an air suspension with variable
damping for improved driving comfort. All-round
level control ensures the best possible suspen-
sion and constant ground clearance, even with a
laden vehicle. When you drive fast, the vehicle is
lowered automatically 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 control
and ADS PLUS (Adaptive Damping System with
continuous damping adjustment).
The vehicle level can be set using the DYNAMIC
SELECT switch (
Ypage 130) or the level button
(Ypage 164). The setting always corresponds
to the last selected function.
Important safety notes
GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
iIf one of the doors is open, the vehicle is not
lowered.
