The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there isamalfunction in
the system, it may not be possible to apply the
released parking brake.
XIf this is the case, only park the vehicle on
level ground and secure it to prevent it rolling
away.
XShift the automatic transmission to position
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. Contact a
qualified specialist workshop.
The electric parking brake performs afunction
test at regular intervals while the engine is
switched off. The sounds that can be heard while
this is occurringa re normal.

154Parking
Driving and parking

When you take advantage of engine braking, a
drive wheel may not turn for some time, e.g.
on aslippery road surface. This could cause
damage to the drive train. This type of damage is not covered by the Mercedes-Benz war-
ranty.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stoppin gdistanc eand can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as afootrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!Depressin gthe brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately. Drive
on for ashort while. This allows the airflow to
cool the brakes more quickly.
Wet roads
If you have driven for along time in heavy rain
without braking, there may be adelayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain agreater distanc efrom the
vehicle in front.
After driving on awet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, alayer of salt resi-
due may form on the brake discs and brake
pads. This can result in asignificantly longer
braking distance.
RIn order to prevent any salt build-up, apply the
brakes occasionally while paying attention to
the traffic conditions.
RCarefully depress the brake pedal and the
beginnin gand end of ajourney.
RMaintain agreater distanc etothe vehicle
ahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up in
the instrument cluster and
Ryou hear awarning ton ewhile the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately. Consult aqualified specialist workshop to
arrange this.
!Vehicles with 4MATIC: function or per-
formance test smay only be carried out on a2-
axle dynamometer. If you wish to operate the
vehicle on such adynamometer, please con-
sult aqualified specialist workshop in
advance. You could otherwise damage the
drive train or the brake system.
!Vehicles with 4MATIC: the ESP®system
operates automatically. The engine and the
ignition must therefore be switched off (the
SmartKey must be in position 0or 1in the
ignition lock or the Start/Stop button must be
in position 0or 1)ift he electric parking brake
is tested on abrake dynamometer.
Brakin gtriggered automatically by ESP
®may
cause severe damage to the brake system.
All checksa nd maintenance work on the brake
system must be carried out at aqualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at aqualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the functional-
ity of your brakes at regular intervals.

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 automaticallytoi mprove driving safety
and to reduce fuel consumption. There is also
the option to manuallya djust the vehicle level.
AIRMATIC consists of level setting, level control
and ADS (Adaptive Damping System).
The vehicle level can be set using the DYNAMIC
SELECT switch (
Ypage 139) or the level button
(Ypage 172). The setting always corresponds
to the last selected function.
