consumers.Ignition (or position 2)
Press KEYLESS-GO start/stop button
twice.
This supplies power for all electrical
consumers. All lamps (except high

turn signal indicator lamps unless acti-
vated) in the instrument cluster come
on. If a lamp in the instrument cluster
fails to come on when the ignition is
switched on, have it checked and
replaced if necessary. If a lamp in the
instrument cluster remains on after
starting the engine or comes on while
driving, see “Lamps in instrument clus-
ter” (
page 344).For information on starting the engine us-
ing the KEYLESS-GO start/stop button

iWhen you switch on the ignition, the
indicator and warning lamps (except high beam

tor lamps unless activated) in the instrument
cluster come on. The indicator and warning
lamps (except high beam headlamp indicator
lamp and turn signal indicator lamps if activated)
should go out when the engine is running. This in-
dicates that the respective systems are opera-
tional.

Getting out of your vehicle with the gear
selector lever not fully engaged in positionP
is dangerous. Also, when parked on an in-
cline, positionP alone may not prevent your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to positionP.
When parked on an incline, turn front wheels
towards the road curb.

64 Safety and Security
Occupant safety
In this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are
Seat belts (page 76)
Child restraints (page 82)
Lower Anchors and Tethers for
CHildren (LATCH) (
page 86)
Additional protection is provided by
Supplemental Restraint System (SRS)
with
Air bags (page 66)
Air bag control unit (with crash
sensors)
Emergency Tensioning Device
(ETD) for seat belts (

Classification System (OCS)
(
page 71)
Although independent systems, their pro-
tective functions work in conjunction with
each other.The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The 1indicator lamp in the instrument
cluster lights up when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the 1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the 1indicator lamp:
fails to go out after approximately
4 seconds after the engine was started
does not come on at all
comes on after the engine was started
or while driving

89 Safety and Security
Driving safety systems
Driving safety systems
In this section you will find information on
the following driving safety systems:
ABS (Antilock Brake System)
Adaptive Brake
BAS (Brake Assist System)
EBP (Electronic Brake Proportioning)
ESP® (Electronic Stability Program)
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
respond even with 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.
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 driving safety systems described in this
section cannot reduce these risks or pre-
vent the natural laws of physics from acting
on the vehicle.
Always adapt your driving style to the pre-
vailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
iIn winter operation, the maximum
effectiveness of the ABS, BAS, ESP® and Adap-
tive Brake is only achieved with winter tires
(
page 328) 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.
92 Safety and Security
Driving safety systems
EBP
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allow-
ing the rear brakes to supply a greater pro-
portion of the braking effort in straight line
breaking without a loss of vehicle stability.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 the 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 slippery road surfaces. The ESP
®
also stabilizes the vehicle during braking
and steering maneuvers.
The ESP
® warning lamp v in the
instrument cluster flashes when the ESP®
is engaged.
The 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
When the EBP is malfunctioning, the ABS,
BAS, ESP® are also switched off.
If the EBP is malfunctioning, the brake sys-
tem will still function with full brake boost.
However, the rear wheels could lock up dur-
ing emergency braking situations, for exam-
ple. You could lose control of the vehicle and
cause an accident. Adapt your driving style
to the changed driving characteristics.
Warning!G
Never switch off the ESP® when you see the
ESP® warning lamp v flashing in the in-
s t r u m e n t c l u s t e r . I n t h i s c a s e p r o c e e d a s f o l -
lows:
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.
94 Safety and Security
Driving safety systems
Switching off the ESP®
Switching off the ESP®
(except CLS 63 AMG)
To improve the vehicle’s traction, switch
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:
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 traction control 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*
the cruise control or Distronic* switch
off if currently activatedThe switch is located on the center con-
sole.
1ESP
® switch
With the engine running, press ESP®
switch1 until the ESP® warning
lampv in the instrument cluster
comes on.
The ESP
® is switched off.
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.
Do not switch off the ESP
® when a spare
wheel is mounted.
Warning!G
Switch on the ESP® immediately if the afore-
mentioned circumstances do not apply any-
more. Otherwise the ESP
® will not stabilize
the vehicle when it is starting to skid or a
wheel is spinning.
iWhen the ESP® is switched off and one or
more drive wheels are spinning, the ESP® warn-
ing lamp v in the instrument cluster flashes.
However, the ESP
® will then not stabilize the ve-
hicle.
