Electro-hydraulic brake system
The electro-hydraulic brake system combines
a hydraulic brake circuit with electronically
controlled brake servo assistance. You have
increased braking safety and improved
braking comfort.GWarning!
Never ignore a brake malfunction indicated in
the speedometer display, for example by the
$ (USA only) or J (Canada only)
indicator lamp. Refer to the “Practical hints”
section. Also read and observe the messages
in the instrument cluster multifunction
display.
For information on warning and indicator
lamps, see the “Practical hints” section
( Y page 255). For information on the
messages that may appear in the
multifunction display, see the “Practical
hints” section ( Y page 227) and
( Y page 237).
GWarning!
The electro-hydraulic brake system requires
electrical power to operate.
A malfunction in the vehicle’s power supply or
electrical system may impair brake system
operation and switch it into its emergency
operation mode. In such a case, the red brake
warning lamp comes on and warning
messages appear in the multifunction display
while driving. To brake, the driver must then
apply significantly greater brake pedal
pressure and depress the pedal much further
to obtain the expected braking effect. If
necessary, apply full pressure to the brake
pedal. Brakes are only applied to the front
wheels. Stopping distance is increased!
If there is a malfunction in the electro-
hydraulic brake system, we recommend that
the vehicle be transported with all wheels off
the ground using flatbed or appropriate wheel
lift/dolly equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on the
ground is only permissible for distances up to
30 miles (50 km) and at a speed not to exceed
30 mph (50 km/h). For more information, see
the “Towing the vehicle” section in this
Operator’s Manual.
The electro-hydraulic brake system is
activated automatically when you
R unlock the vehicle with the SmartKey or
with KEYLESS-GO
R open the driver’s or passenger door
R turn the SmartKey in the starter switch to
position 1
R press the start/stop button on the gear
selector lever once (vehicles with
KEYLESS-GO)
R depress the brake pedal
R release the parking brake
If the electro-hydraulic brake system is
activated as the brake pedal is first
depressed, you may feel a reduced pedal
resistance and longer pedal travel than
normal. When releasing the pedal, you may
also feel the brake pedal pulsate and you may
hear a sound which is caused by the
activation of the electro-hydraulic brake
system pump. This is normal and not an
indication of a malfunction. Pedal travel
returns to normal when you release the brake
pedal and the sound soon ceases.
If you experience the above while driving and
the red brake warning lamp illuminates
and/or warning messages appear in the
multifunction display, the brake system is
malfunctioning. Follow the instructions of the
warning message(s) and have the brake
system checked immediately.GWarning!
Have brake pad replacement and other work
on the electro-hydraulic brake system carried

Power closing assist for trunk lid
It is not necessary to slam the trunk lid
closed. An electrical power-assisted
mechanism draws the trunk lid closed quietly
and automatically once the trunk lid has been
latched. When the electrical power-assisted
mechanism has stopped, the trunk can be
reopened.
GWarning!
To prevent possible personal injury, always
keep hands and fingers away from the trunk
opening when closing the trunk lid. Be
especially careful when small children are
around.
In case of danger, pull the inside or outside
door handle, or press the trunk lid lock.
To prevent personal injury, never actuate the
closing assist mechanism by tampering with
the door or trunk lid latch.
GWarning!
Make sure the trunk is closed when the engine
is running and while driving. Among other
dangers, deadly carbon monoxide (CO) gases
may enter vehicle interior resulting in
unconsciousness and death.
