Occupant safety
Introduction
In this section you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint systems are:
R Seat belts
R Child restraints
R
Lower Anchors and Tethers for CHildren
(LATCH) also known as ISOFIX
Additional protection potential is provided by:
R
Supplemental Restraint System (SRS) with
- Air bags
- Air bag control unit (with crash sensors)
-
Emergency Tensioning Device (ETD) for
seat belts
- Seat belt force limiter
R NECK-PRO active front head restraints
R
Preventive occupant safety (PRE-SAFE ®
)
R Air bag system components with
- Front passenger front air bag off
indicator lamp
- USA only: Front passenger seat with
Occupant Classification System (OCS)
- Canada only: Front passenger seat with
BabySmart™ air bag deactivation system
Although the systems are independent, their
protective functions work in conjunction with
each other.
GWarning!
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
i See “Children in the vehicle”
( Y page 56) for information on
R infants and children traveling with you in
the vehicle
R restraint systems for infants and children
SRS indicator lamp
The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of system malfunctions.
The SRS indicator lamp 6 in the
instrument cluster comes on when the
ignition is switched on. It goes out no later
than a few seconds after the engine has been
started.
The SRS components are in operational
readiness when the SRS indicator lamp
6 is not lit while the engine is running.

A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates.
RIf you have to place a child in a forward-
facing child restraint on the front passenger
seat, move the seat as far back as possible,
use the proper child restraint
recommended for the age, size and weight
of the child, and secure child restraint with
the vehicle’s seat belt according to the child
seat manufacturer’s instructions. For
children larger than the typical 12-month-
old child, the front passenger front air bag
may or may not be activated.
Deployment of the driver front air bag does
not mean that the front passenger front air
bag also should have deployed.
The OCS may have determined
Rthat the seat was empty or occupied by the
weight up to or less than that of a typical
12-month-old child seated in a standard
child restraint – both of which are instances
where the system suppresses deployment
of the front passenger front air bag even
though the impact met the criteria and was
of sufficient severity to deploy the driver
front air bag
Rthat the seat was occupied by a small
individual (such as a young teenager or a
small adult) or a child who weighs more
than the weight of a typical 12-month-old
child in a standard child restraint – both of
which are instances where the system may
suppress deployment of the front
passenger front air bag even though the
impact met the criteria and was of
sufficient severity to deploy the driver front
air bag
45 indicator lamp : will be
illuminated, except with the SmartKey
removed from the starter switch or with the
starter switch in position 0.
GWarning!
If the red SRS indicator lamp 6 in the
instrument cluster and the 45
indicator lamp are lit at the same time, there
is a malfunction in the OCS. The front
passenger front air bag will be deactivated in
this case. Have the system checked by
qualified technicians as soon as possible.
Contact an authorized Mercedes-Benz
Center.
Only have the seat repaired or replaced at an
authorized Mercedes-Benz Center.
In order to ensure proper operation of the air
bag system and OCS:
RSit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
RWhile seated, an occupant should not
position him/herself in such a way as to
cause the occupant’s weight to be lifted
from the seat bottom as this may result in
the OCS being unable to correctly
approximate the occupant’s weight
category.
RRead and observe all warnings in this
chapter.

RAdjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder.
RPlace the lap portion of the seat belt as low
as possible on your hips.
Seat and head restraint
GObserve Safety notes, see page 87.XPosition seat = and head restraint
properly. See (Y page 88) for seat and
head restraint adjustment.
Observe the following points:
RAlways be in a properly seated position.
RThe position should be as far rearward from
the front air bag in the steering wheel as
possible, while still permitting proper
operation of vehicle controls.
RAdjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely.
RThe seat must be adjusted so that you can
correctly fasten and position your seat belt.
RThe seat backrest must be in a position that
is as nearly upright as possible.
RAdjust the seat cushion so that the front
edge of the seat cushion lightly supports
your legs.
RAdjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports the
back of the head at eye level.
RNever place hands under the seat or near
any moving parts while the seat is being
adjusted.
Occupant safety55Safety and security212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 55Z
iIn winter operation, the maximum
effectiveness of most of the driving
systems described in this section is only
achieved with winter tires, or snow chains
as required.
Safety notesGWarning!
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the natural laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear.
ABSGObserve Safety notes, see page 62.GWarning!
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
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) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp ! in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal. The pulsation indicates that the
ABS is in the regulating mode.
XKeep firm and steady pressure on the brake
pedal while you feel the pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Emergency brake maneuver
XKeep continuous full pressure on the brake
pedal.62Driving safety systemsSafety and security
212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 62
boost to a level that is suitable for the traffic
situation.
If BAS PLUS requires a particularly high brake
power boost, PRE-SAFE ®
is activated at the
same time.XKeep constant pressure on the brake pedal
until the emergency braking situation is
over.
During this process, the ABS prevents the
wheels from locking up.
The brakes will resume normal operation
after
R the brake pedal is released
R no obstacles are detected in your path
R the system no longer senses a risk of a
collision
BAS PLUS is then deactivated.
BAS PLUS can react to stationary obstacles
such as standing or parked vehicles at road
speeds of up to approximately 40 mph
(70 km/h).
BAS PLUS can only assist you when the radar
sensors are switched on and functional. You
can check whether the sensors are active by
switching on DISTRONIC PLUS
( Y page 149) or using the Radar sensors
function in the instrument cluster control
system.
GWarning!
BAS PLUS will only respond with brake
assistance if it has clearly detected an object.
Detection can be impeded by
R dirty or covered sensors
R snowfall or heavy rain
R disturbance from other radar sources
R strong radar reflection such as in parking
garages
BAS PLUS uses radar signals that are not
reflected well by narrow objects and
absorptive materials. For this reason BAS
PLUS will not react to persons, animals, and
approaching traffic or cross-traffic.
BAS PLUS may not detect narrow vehicles
driving in front of you, such as motorcycles
and vehicles driving offset from your vehicle
center.
After a hard collision or damage to the front
of the vehicle from an accident, have the
adjustment and operation of the radar
sensors checked by an authorized Mercedes-
Benz Center.
If BAS PLUS is not available due to a radar
sensor malfunction, the braking system will
continue to function normally with full brake
boost and full standard BAS function.
Adaptive Brake
Adaptive Brake provides a high level of
braking safety as well as increased braking
comfort. Adaptive Brake takes driver and
vehicle characteristics into consideration,
thus achieving an optimal braking effect.
In addiditon, Adaptive Brake provides the
HOLD function (Y page 161) and the hill-start
assist system ( Y page 160).
For more information on the brake system,
see ( Y page 254).
EBP
GObserve Safety notes, see page 62.
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allowing
the rear brakes to supply a greater proportion
of the braking effort in straight-line braking
without a loss of vehicle stability.
GWarning!
If the EBP malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics.

ESCGObserve Safety notes, see page 62.
The Electronic Stability Control (ESC) is
operational as soon as the engine is running.
It monitors the vehicle’s traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESC recognizes that the vehicle deviates
from the direction of travel as intended by the
driver. By applying brakes to individual
wheels and by limiting the engine output, the
ESC works to stabilize the vehicle. The ESC is
especially useful while driving off and on wet
or slippery road surfaces. The ESC also
stabilizes the vehicle during braking and
steering maneuvers.
The ESC warning lamp ä in the instrument
cluster comes on when you switch on the
ignition. It goes out when the engine is
running.
GWarning!
Never switch off the ESC when you see the
ESC warning lamp ä flashing in the
instrument cluster. In this case proceed as
follows:
R When driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESC cannot
prevent accidents resulting from excessive
speed.
! Vehicles with 4MATIC: Because the ESC
operates automatically, the engine and
ignition must be shut off (SmartKey in
starter switch position 0 or 1 or KEYLESS-
GO start/stop button in position 0 or 1)
when the parking brake is being tested on
a brake test dynamometer.
Active braking action through the ESC may
otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
! Vehicles without 4MATIC: Because the
ESC operates automatically, the engine
and ignition must be shut off (SmartKey in
starter switch position 0 or 1 or KEYLESS-
GO start/stop button in position 0 or 1)
when the parking brake is being tested on
a brake test dynamometer or when the
vehicle is being towed with one axle raised.
Active braking action through the ESC may
otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
! The ESC will only function properly if you
use wheels of the recommended tire size
as specified in the “Technical data” section
of this Operator’s Manual.
i The DISTRONIC PLUS and cruise control
switch off automatically when the ESC
engages.
Electronic Traction System
(ETS/4-ETS) GObserve Safety notes, see page 62.
The ETS (Electronic Traction System) and
4-ETS (four-wheel Electronic Traction
System, vehicles with 4MATIC only) are
components of the ESC. The ETS/4-ETS
improves the vehicle’s ability to utilize
available traction, especially under slippery
road conditions by applying the brakes to a
spinning wheel. Vehicles with 4MATIC also
transfer more power to the wheel(s) with
traction.
When you switch off the ESC, the
ETS/4-ETS is still enabled.
Driving safety systems65Safety and security212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 65Z
Switching the ESC off or on
(except E 63 AMG)
GWarning!
The ESC should not be switched off during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not switch off the ESC when a spare wheel
is mounted.
To improve the vehicle’s traction, switch off
the ESC. This allows the drive wheels to spin
and thus cut into surfaces for better grip, for
example
Rwhen driving with snow chains
Rin deep snow
Rin sand or gravel
GWarning!
Switch on the ESC immediately if the
aforementioned circumstances do not apply
anymore. Otherwise the ESC will not stabilize
the vehicle when it is starting to skid or a
wheel is spinning.
When you switch off the ESC,
Rthe ESC does not stabilize the vehicle
Rthe engine output is not limited, which
allows the drive wheels to spin and thus cut
into surfaces for better grip
Rthe ETS/4-ETS will still apply the brakes to
a spinning wheel
Rthe ESC continues to operate when you are
braking
Rthe cruise control or the DISTRONIC PLUS
cannot be activated
Rthe cruise control or the DISTRONIC PLUS
switch off if activated
iWhen the ESC is switched off and one or
more drive wheels are spinning, the ESC
warning lamp ä in the instrument
cluster flashes. However, the ESC will then
not stabilize the vehicle.
XSwitching off: With the engine running,
press ESC switch : until the ESC OFF
warning lamp å in the instrument
cluster comes on.
The ESC is switched off.
GWarning!
When the ESC OFF warning lamp å is on,
the ESC is switched off.
When the ESC warning lamp ä and the
ESC OFF warning lamp å are on
continuously, the ESC is not operational due
to a malfunction.
When the ESC is switched off or not
operational, vehicle stability in standard
driving maneuvers is reduced.
Adapt your speed and driving to the prevailing
road conditions and to the non-operating
status of the ESC.
! Avoid spinning of a drive wheel for an
extended period with the ESC switched off.
This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
XSwitching on: Press ESC switch : until
the ESC OFF warning lamp å in the
instrument cluster goes out.
You are now again in normal driving mode
with the ESC switched on.

Switching ESC SPORT on or off
GWarning!
ESC SPORT should not be switched on during
normal driving.
Switching ESC SPORT on will result in the
following:
Rno restriction to engine torque
Rsystem-supported traction control is
limited
ESC SPORT is designed for driving on closed
tracks when the vehicle’s natural oversteer
and understeer characteristics are desired
and requires a highly skilled and experienced
driver able to handle these critical driving
situations.
You could lose control of your vehicle and
cause an accident.
Please be aware of these limits when you
switch on ESC SPORT.
Do not switch on ESC SPORT when a spare
wheel is mounted.
To improve the vehicle’s traction, switch on
ESC SPORT. This allows the drive wheels to
spin and thus cut into surfaces for better grip,
for example
Rwhen driving with snow chains
Rin deep snow
Rin sand or gravel
GWarning!
Switch off ESC SPORT and switch on the ESC
immediately if the aforementioned
circumstances do not apply anymore.
Otherwise ESC will only stabilize the vehicle
to a limited extent when it is starting to skid
or a wheel is spinning.
When you switch on ESC SPORT
Rthe ESC stabilizes the vehicle only to a
limited extent
Rthe engine output is limited, but only to the
extent that allows the drive wheels to spin
and thus cut into surfaces for better grip
Rthe ETS will still apply the brakes to a
spinning wheel
Rthe ESC continues to operate when you are
braking hard
Rthe cruise control or the DISTRONIC PLUS
cannot be activated
Rthe cruise control or the DISTRONIC PLUS
switch off if activated
