70 Safety and SecurityDriving safety systems
ESP
The Electronic Stability Program (ESP)
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 ABS/ESP warning lamp
v
in the
speedometer dial flashes when the ESP is
engaged.
The warning lamp
v
in the speedome-
ter dial (
page 21) lights up when you
turn the key to position1 or2. It goes out
when you start the engine
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. The BAS cannot
prevent accidents, including those resulting
from excessive speed in turns, following an-
other vehicle too closely, or hydroplaning.
Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities 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.
Warning!
G
Never switch off the ESP when you see the
ABS/ESP-warning lamp
v
flashing in
the speedometer dial. 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.

71 Safety and Security
Driving safety systems
Switching off 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 gravel
Warning!
G
The ESP cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
cannot prevent accidents, including those
resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ESP 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.
!Because of ESP’s automatic operation,
the engine must be shut off 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
rear axle brake system.
ESP will only function properly if you
use wheels of the recommended tire
size (page 337).
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.iDistronic* cannot be activated when
ESP has been deactivated.

72 Safety and SecurityDriving safety systemsThe button is located in the lower part of
the center console.

Press ESP button1 until the ESP warn-
ing lamp
v
in the speedometer
lights up.
ESP is deactivated.
If one or more wheels are spinning, the
ESP warning lamp v
in the speedome-
ter flashes, regardless of the speed.
Traction control brakes a spinning wheel
even when ESP is deactivated.
ESP always operates when you are brak-
ing, even when it has been deactivated.Switching on ESP

Press button1.
The ESP warning lamp
v
in the
speedometer goes out. You are now
again in normal driving mode.
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.
!Avoid spinning of a drive wheel for an
extended period with the ESP switched
off. This may cause serious damage to
the drive train which is not covered by
the Mercedes-Benz Limited Warranty.Warning!
G
When the ESP warning lamp
v
is
illuminated continuously, ESP is switched
off.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP.
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 253). Also read and ob-
serve the messages in the instrument clus-
ter display (page 257).

73 Safety and Security
Driving safety systems
The SBC brake system is automatically ac-
tivated when you:

unlock the vehicle with the key or the
KEYLESS-GO* card


open the driver’s or passenger door


turn the key in the starter switch to
position1


in vehicles with KEYLESS-GO*, press
start/stop button on 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 253) and
the warning messages (
page 265) light up
while driving. To brake, the driver must then
apply significantly greater brake pedal pres-
sure and depress the pedal much further to
obtain the expected braking effect. If neces-
sary, 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 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 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 in-
formation, refer to “Towing the vehicle”
(page 325).
iIf the SBC 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 SBC 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.
