In this section you will find information on
the following driving safety systems:

ESP
® (E
lectronic S
tability P
rogram)
Electro-hydraulic brake system
ABS
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) indepen-
dent of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
Warning!
G
The following factors increase the risk of ac-
cidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely
The ABS, BAS, ESP
®, and the electro-hy-
draulic brake system cannot reduce this
risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
i
In winter operation, the maximum effective-
ness of the ABS, the BAS, the ESP
®, and the
electro-hydraulic brake system is only achieved
with winter tires (
page 316) or snow chains as
required.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.
88 Safety and SecurityDriving safety systemsThe - indicator lamp in the instrument
cluster comes on when you switch on the
ignition. It goes out when the engine is run-
ning.
Braking
If the ABS activates during braking, the
ABS/ESP
® warning lamp v in the in-
strument cluster dial flashes. Because of
the electro-hydraulic brake system, you
will not feel any pulsation in the brake ped-
al.
Keep firm and steady pressure on the
brake pedal.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.The ABS/ESP
® warning lamp v flashes
whenever the ABS is activated which can
be an indication of hazardous road condi-
tions and functions as a reminder to take
extra care while driving.
Emergency brake maneuver
Keep continuous, full pressure on the
brake pedal.
For more information, see the
“Practical hints” section (
page 332).
Warning!
G
When the ABS is malfunctioning, the BAS
and the ESP
® are also switched off.
When the ABS is malfunctioning, the wheels
may lock during hard braking, reducing
steering capability and extending the brak-
ing distance.
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded. The ABS cannot prevent acci-
dents, including those resulting from exces-
sive speed in turns, following another
vehicle too closely, or hydroplaning. Only a
safe, attentive, and skillful driver can pre-
vent accidents. The capabilities of an ABS
equipped vehicle must never be exploited in
a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
89 Safety and Security
Driving safety systems
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing the braking distance.
Apply continuous full braking pressure
until the emergency braking situation is
over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the
brakes function again as normal. The BAS
is then deactivated.
ESP
®
The Electronic Stability Program (ESP
®) is
operational as soon as the engine is run-
ning and monitors the vehicle’s traction
(force of adhesive friction between the
tires and the road surface) and handling.
The ESP
® recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting engine output, the ESP
® works
to stabilize the vehicle. The ESP
® is espe-
cially useful while driving off and on wet or
slippery road surfaces. The ESP® also sta-
bilizes the vehicle during braking maneu-
vers.
The ABS/ESP
® warning lamp v in the
instrument cluster (
page 27) flashes
when the ESP
® is engaged.
The ABS/ESP® warning lamp v in the
instrument cluster comes on when you
switch on the ignition. It goes out when the
engine is running.
Warning!
G
If the BAS is malfunctioning, the brake sys-
tem is still functioning normally, but without
the additional brake boost available that
BAS would normally provide in an emergen-
cy braking maneuver. Therefore, the braking
distance may increase.
Warning!
G
BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that af-
forded by the condition of the vehicle brakes
and tires or the traction afforded. The BAS
cannot prevent accidents, including those
resulting from excessive speed in turns, fol-
lowing another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of a BAS equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
90 Safety and SecurityDriving safety systems
For more information, see the
“Practical hints” section (
page 332) and
(
page 355).
Warning!
G
Never switch off the ESP
® when you see the
ABS/ESP
® warning lamp v flashing in
the instrument cluster. In this case proceed
as follows:
While driving off, apply as little throttle
as possible.
While driving, ease up on the accelera-
tor.
Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP
® cannot prevent accidents result-
ing from excessive speed.

ous manner which could jeopardize the us-
er’s safety or the safety of others.
!
Because the ESP
® operates automatically,
the engine must be shut off (SmartKey in starter
switch position 0 or 1or KEYLESS-GO*
start/stop button in position 0 or 1) when
the parking brake is being tested on a brake
test dynamometer
the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system.
The ESP
® will only function properly if you use
wheels of the recommended tire size
(
page 435).
i
The cruise control and the Distronic* sys-
tem deactivate automatically when the ESP
® is
in operation (
page 220).
91 Safety and Security
Driving safety systems
Electronic traction system
The electronic traction system is a compo-
nent of ESP
®.
The electronic traction system improves
the vehicle’s ability to utilize available trac-
tion, especially under slippery road condi-
tions by applying the brakes to a spinning
wheel.
When you switch off the ESP
®, the elec-
tronic traction system is still enabled.Switching off the ESP
®
To improve the vehicle’s traction, switch
off the ESP
® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:
when driving with snow chains
in deep snow
in sand or gravelWhen you switch off the ESP
®
the ESP
® does not stabilize the vehicle
the engine output is not limited, which
allows the drive wheels to spin and
thus cut into surfaces for better grip
the electronic traction system will still
apply the brakes to a spinning wheel
the ESP
® continues to operate when
you are braking
you cannot activate the cruise control
or the Distronic* system
the cruise control or the Distronic* sys-
tem switch off if currently activated
Warning!
G
If you are driving too fast, the electronic
traction system cannot reduce the risk of an
accident.
The electronic traction system cannot pre-
vent the natural laws of physics from acting
on the vehicle.
Warning!
G
ESP
® should not be switched off during nor-
mal driving other than in the circumstances
described below. Disabling of the system
will reduce vehicle stability in standard driv-
ing maneuvers.
Do not switch off the ESP
® when a spare
wheel is mounted.
!
Switch on the ESP
® immediately if the
aforementioned circumstances do not apply
anymore.
i
When the ESP
® is switched off and one or
more drive wheels are spinning, the ABS/ESP
®
warning lamp v in the speedometer flashes.
However, the ESP
® will then not stabilize the
vehicle.
92 Safety and SecurityDriving safety systemsThe switch is located in the lower part of
the center console.
1ESP
® switch
Press ESP
® switch1 until the
ABS/ESP® warning lamp v in the
instrument cluster comes on.
The ESP
® is deactivated.
Switching on the ESP
®
Press ESP
® switch1.
The ABS/ESP® warning lamp v in
the instrument cluster goes out.
You are now again in normal driving
mode with the ESP
® switched on.
Electro-hydraulic brake system
The electro-hydraulic 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 ABS/ESP
® warning lampv is
illuminated continuously, the ESP
® is
switched off or is not operational due to a
malfunction. Vehicle stability in standard
driving maneuvers reduces.
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 ex-
tended 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!

Never ignore a brake malfunction indicated
in the speedometer display, for example by
the;(USA only) or3(Canada only)
indicator lamp. Refer to the “Practical hints”
section (
page 335). Also read and ob-
serve the messages in the instrument clus-
ter multifunction display (
