4MATIC (Four Wheel Electronic
Traction 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.
The - indicator lamp in the instrument
cluster comes on when you switch on the
ignition. It goes out when the engine is run-
ning.
iIn winter operation, the maximum
effectiveness of the ABS, the BAS, the
ESP, SBC and 4MATIC is only achieved
with winter tires (M + S tires), or snow
chains as required.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, SBC and 4MATIC cannot
reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
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 systemsBraking
If the ABS activates during braking, the
ABS/ESP warning lamp v in the instru-
ment cluster dial flashes. Because of the
SBC brake system, you will not feel any
pulsation in the brake pedal.
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 353).
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 af-
forded. The ABS cannot prevent accidents,
including those resulting from excessive
speed in turns, following another vehicle too
closely, or hydroplaning. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ABS equipped
vehicle must never be exploited in a reck-
less or dangerous manner which could jeop-
ardize 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 especially
useful while driving off and on wet or slip-
pery road surfaces. The ESP also stabilizes
the vehicle during braking maneuvers.
The ABS/ESP warning lamp v in the in-
strument cluster 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
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that
afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The BAS cannot prevent accidents, includ-
ing those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of a BAS equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.

90 Safety and SecurityDriving safety systems
For more information, see the “Practical
hints” section (
page 353).
Warning!
G
Never switch off the ESP when you see the
ABS/ESP warning lamp v fla s hi n g in th e
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 resulting
from excessive speed.

you use wheels of the recommended
tire size (
page 443).
!Vehicles without 4MATIC:
Because of the ESP’s automatic opera-
tion, the engine and ignition must be
shut off (SmartKey in starter switch
position0 or1 or KEYLESS-GO
start/stop button* in position0 or1)
when:

the parking brake is being tested on
a brake test dynamometer


the vehicle is being towed with the
front axle raised
Active braking action through the ESP
may otherwise seriously damage the
brake system.
For information on vehicles with
4MATIC, see “Four wheel electronic
traction system (4MATIC) with the
ESP” (
page 95).

91 Safety and Security
Driving safety systems
Switching off the ESP
To improve the vehicle's traction, turn off
the ESP in driving situations where it would
be advantageous to have drive wheels spin
and thus cut into surfaces for better grip
such as:

starting out on slippery surfaces and in
deep snow in conjunction with snow
chains


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 traction control will still brake a
spinning wheel


the ESP continues to operate when you
are braking


you cannot activate Distronic*The switch is located on the center con-
sole.
1ESP off/on switch

Press ESP switch 1 until the
ABS/ESP warning lamp v in the
instrument cluster comes on.
The ESP is deactivated.
Warning!
G
The ESP should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in driving
maneuvers.!Turn on the ESP immediately if the
aforementioned circumstances do not
apply anymore.
iWhen 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 systems
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.
SBC brake system
The SBC brake system combines a hydrau-
lic brake circuit with electronically con-
trolled brake servo assistance. You have
increased braking safety and improved
braking comfort.
Warning!
G
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 354). Also read and ob-
serve the messages in the instrument clus-
ter display (page 362).

93 Safety and Security
Driving safety systems
The SBC brake system is automatically
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 gear selector
lever once


depress the brake pedal


release the parking brake
Warning!
G
The SBC 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 354) and
warning messages in the instrument cluster
(
page 362) 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 SBC 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 cir-
cumstances do not permit the use of the
recommended towing methods and the ve-
hicle 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 vehi-
cle” (
page 430).
