When the ABS/ESP
® warning lamp v 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.
!Turn on the ESP
® immediately if the
aforementioned circumstances do not
apply anymore.
Warning!
G
Never ignore a brake malfunction indicated
in the speedometer display, for example by
the ; (USA only) or 3 (Canada only)
warning lamp. Refer to the “Practical hints”
section (
page 376). Also read and ob-
serve the messages in the instrument clus-
ter display (page 386).
98 Safety and SecurityDriving safety systems
The electrohydraulic brake system is auto-
matically activated when you
unlock the vehicle with the SmartKey
or the KEYLESS-GO*
open the driver’s or passenger door
turn the SmartKey in the starter switch
to position1
in vehicles with KEYLESS-GO*, press
the start/stop button on the gear se-
lector lever once
depress the brake pedal
release the parking brake
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 376) and
warning messages in the instrument cluster
(
page 386) come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and de-
press the pedal much further to obtain the
expected braking effect. If necessary, apply
full pressure to the brake pedal. Brakes may
only be applied to the front wheels. Stop-
ping 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.
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
u p t o 3 0 m i l e s ( 5 0 k m ) a n d a t a s p e e d n o t t o
exceed 30 mph (50 km/h). For more infor-
mation, refer to “Towing the vehicle”
(page 457).
iIf the electrohydraulic brake system is
activated as the brake pedal is first de-
pressed, 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 mal-
function. Pedal travel returns to normal
when you release the brake pedal and
the sound soon ceases.
If you experience the above while driv-
ing and the red brake warning lamp
(page 376) illuminates and/or warn-
ing messages appear in the instrument
cluster (
page 386), the brake system
is malfunctioning. Follow the instruc-
tions of the warning message(s) and
have the brake system checked imme-
diately.

Warning!
G
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the
hands-free device and only use the tele-
phone when weather, road and traffic condi-
tions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.
304 OperationDriving instructionsPower assistance
Brakes
Warning!
G
The brake system requires electrical energy
for operation.
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 376) and
warning messages in the instrument cluster
(
page 386) come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and de-
press the pedal much further to obtain the
expected braking effect. If necessary, apply
full pressure to the brake pedal. Brakes may
only be applied to the front wheels. Stop-
ping 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. 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,
refer to “Towing the vehicle” (
page 457).
For more information, see “Electrohydraulic
brake system” (
page 97).
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle.
Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking ef-
fect. Maintain a safe distance from vehicles
in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.
