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

ABS (A

ssist S
ystem)


ESP
® (E
lectronic S
tability P
rogram)


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 ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The- indicator lamp in the instrument
cluster (
page 24) comes on when you
switch on the ignition. It goes out when the
engine is running.
iIn winter operation, the maximum
effectiveness of the ABS, ESP
®, and
4MATIC (if so equipped) is only
achieved with winter tires
(
page 336), or snow chains as re-
quired.
Warning!
G
The following factors increase the risk of
accidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The ABS, BAS, ESP
®, and 4MATIC (if so
equipped) cannot reduce this risk.
Always adjust your driving style to the
prevailing 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.

89 Safety and Security
Driving safety systems
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
spinning or if the vehicle starts to skid. By
applying brakes to the appropriate wheel
and by limiting the engine output, the ESP
®
works to stabilize the vehicle. The ESP
® is
especially useful while driving off and on
wet or slippery road surfaces. The ESP®
also stabilizes the vehicle during braking
maneuvers.
The ESP
® warning lampv in the
speedometer flashes when the ESP
® is
engaged.
The ESP
® warning lampv in the
speedometer comes on when you switch
on the ignition. It goes out when the engine
is running.
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
capabilities of a BAS equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the
user’s safety or the safety of others.
Warning!
G
Never switch off the ESP
® when you see the
ESP
® warning lampv flashing in the
speedometer. 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.

90 Safety and SecurityDriving safety systems
For more information, see “Practical hints”
(page 354) and (
page 360).Switching off the ESP
®
To improve the vehicle’s traction, turn 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 gravel

iThe ESP
® will only function properly if
you use wheels of the recommended
tire size (page 432).
!Vehicles without 4MATIC:
Because of the ESP
®’s automatic
operation, the engine must be turned
off (SmartKey in starter switch
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 92).
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 stan-
dard driving maneuvers.
Do not switch off the ESP
® when a Minis-
pare wheel is mounted.

91 Safety and Security
Driving safety systems
When 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 brakingThe switch is located on the upper part of
the center console.

!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
ESP
® warning lampv in the speed-
ometer flashes. However, the ESP
® will
then not stabilize the vehicle.
Warning!
G
When the ESP
® warning lampv 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.

92 Safety and SecurityDriving safety systemsFour wheel electronic traction system (4MATIC) with the ESP
®
Models with all-wheel-drive only.
The 4MATIC improves vehicle’s ability to
use available traction, e.g. during winter
operation in mountains under snowy
conditions, by applying power to all four
wheels.Warning!
