We recommend using Genuine
Mercedes-Benz parts as well as conversion
parts and accessories explicitly approved
by us for your vehicle model.
We have tested these parts to determine
their reliability, safety and special suitabili-
ty for Mercedes-Benz vehicles.We are unable to make an assessment for
other products and therefore cannot be
held responsible for them, even if in indi-
vidual cases an official approval or authori-
zation by governmental or other agencies
should exist. Use of such parts and acces-
sories could adversely affect the safety,
performance or reliability of your vehicle.
Please do not use them.Genuine Mercedes-Benz parts as well as
conversion parts and accessories ap-
proved by us are available at an authorized
Mercedes-Benz Center where you will re-

84 Safety and SecurityDriving safety systemsSwitching on the ESP
®
Press switch1 again.
The ESP
® warning lampv in the
speedometer goes out.
You are now again in normal driving
mode with the ESP
® switched on.
Electrohydraulic brake system
The electrohydraulic brake system com-
bines a hydraulic brake circuit with elec-
tronically controlled brake servo
assistance. You have increased braking
safety and improved braking comfort.
Warning!
G
When the v ABS/ESP
® warning lamp is
illuminated continuously, the ESP
® is
switched off.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP
®.
!Avoid spinning of a drive wheel for an
extended period with the ESP
®
switched off. This may cause serious
damage to the drivetrain which is not
covered by the Mercedes-Benz Limited
Warranty.
Warning!
G
Never ignore a brake malfunction indicated
in the speedometer display, for example by
the ; (USA only) or 3 (Canada only)
indicator lamp. Refer to the “Practical hints”
section (
page 300). Also read and ob-
serve the messages in the instrument clus-
ter multifunction display (
page 319).
Warning!
G
The electrohydraulic brake system requires
electrical power to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. In such a case, the
red brake warning lamp (
page 300)
comes on and warning messages
(
page 319) 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 ef-
fect. If necessary, apply full pressure to the
brake pedal. Stopping distance is increased!
If there is a malfunction in the electrohy-
draulic brake system, we recommend that
the vehicle be transported with all wheels
off the ground using flatbed or appropriate
wheel lift/dolly equipment.
