To be classified correctly, the frontpassenger
must sit:
Rwith the seat belt fastened correctly
Rin a positionthat is as upright as possible
with their back against the seat backrest
Rwith their feet on the floor
The OCS weight sensor reading is affected if
the occupant's weight is transferred, e.g. by
leaning on the armrest.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at a
qualified specialist workshop.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz.
Both the driver and the front passenger
should always observe the
indicator lamp to determine whether or not
the front passenger is positioned correctly.
Observe also the air bag display messages
that can be displayed in the instrument
cluster (Ypage 222).
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy.
The OCS may have detected that the seat:
Ris empty or occupied by the weight of a
typical child up to twelve months old,
seated in a child restraint system
Ris occupied by a small individual, such as a
young teenager or a small adult
Ris occupied by a child in a child restraint
system whose weight is greater than that
of a typical twelve month old child.
These are examples of when the OCS
deactivates the front-passenger front air bag.
Deactivation takes place although the
collision fulfills the criteria for deploying the
driver's air bag.
System self-test
GWARNING
If theindicator lamp does not
illuminate, the system is not functioning. You
must contact an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.
GWARNING
Never place anything betweenseat cushion
and child seat (e.g. a pillow), since it reduces
the effectiveness of the OCS. The underside
and rear side child restraint system must be
placed entirely on the seat cushion and the
backrest of the front-passenger seat
backrest.
If necessary, adjust the tilt of the passenger
seat backrest.
An incorrectly mounted child seat could cause
injuries to the child in case of an accident,
instead of increasing protection for the child.
Follow the manufacturer's instructions for
installation of child restraint systems.
If you turn the SmartKey to position1or2in
the ignition lock, theindicator
lamp illuminates.
If an adult occupant is sitting properly on the
front-passenger seat and the OCS classifies
the occupant as an adult, the
indicator lamp illuminates and goes out again
after approximately six seconds.
If the seat is not occupied and the OCS
classifies the frontpassenger seat as being
unoccupied, theindicator lamp
will illuminate and notgo out.
For more information, see "Problems with the
Occupant Classification System"
(Ypage 49).

GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Ypage 242) and
display messages which may be showninthe
instrument cluster (Ypage 213).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface
conditions. ABS works on slippery roads,
even if you only brake gently.
Braking
XIf ABS intervenes:continue to depress the
brake pedal vigorously until the braking
situation is over.
XTo make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
The pulsating brake pedal can be an
indication of hazardous road conditions, and
functions as a reminder to take extra care
while driving.
BAS (Brake Assist System)
General information
BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes"
section (Ypage 61).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking
XKeep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
COLLISION PREVENTION ASSIST
General notes
COLLISION PREVENTION ASSIST consists of
the Adaptive Brake Assist and the distance
warning function, which are described in the
following.
Distance warning function
Important safety notes
iObserve the "Important safety notes"
section for driving safety systems
(Ypage 61).
GWARNING
The distance warning function does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
62Driving safety systems

Page 65 of 354

Always pay careful attention to the traffic
situationand be ready to brake.
The distance warning functioncannot always
clearly identify objects and complextraffic
situations.
In such cases, the distance warning function
may:
Rgive an unnecessary warning
Rnot give a warning
Always pay careful attention to the traffic
situation and do not rely solely on the
distance warning function.
Function
XTo activate/deactivate:activate or
deactivate the distance warning function in
the on-board computer (Ypage 204).
If the distance warning function is not
activated, thesymbol appears in the
assistance graphics display.
The distance warning function can help you
to minimize the risk of a front-end collision
with a vehicle ahead or reduce the effects of
such a collision. If the distance warning
function detects that there is a risk of a
collision, you will be warned visually and
acoustically.Without your intervention, the
distance warning function cannot prevent a
collision.
Starting at a speed of around 4 mph
(7 km/h) the distancewarning function warns
you if you rapidly approach a vehicle in front.
An intermittentwarning tone will then sound,
and the distance warning lamp will light
up in the instrument cluster.
XBrake immediately in order to increase the
distance from the vehicle in front.
or
XTake evasive action provideditis safe to do
so.
For the distance warning function to assist
you when driving, the function must be
activated in the on-board computer and be
operational (Ypage 204).
Due to the nature of the system, particularly
complicated but non-critical driving
conditions may also cause the system to
display a warning.
With the help of the radar sensor system, the
distance warning function can detect
obstacles that are in the path of your vehicle
for an extended period of time.
From a speed of around 40 mph (70 km/h),
the distance warning function can also react
to stationary obstacles, such as stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision,
the system will initially alert you both visually
and acoustically.
In particular, the detection of obstacles can
be impaired if:
Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain
Rinterference by other radar sources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
Adaptive Brake Assist

ASSIST PLUS can help you to minimize the
risk of a front-end collision with a vehicle
ahead or reduce the effects of such a
collision. If COLLISION PREVENTION ASSIST
PLUS detects that thereis a risk of a collision,
you will be warned visually and acoustically.
In critical situations COLLISION PREVENTION
ASSIST PLUS also initiates automatic
braking.

COLLISION PREVENTION ASSIST PLUS can
brake automatically withinaspeed range of
between 4 mph (7 km/h) and 124 mph
(200 km/h).
COLLISION PREVENTION ASSISTPLUS can
also react to stationary obstacles with
automatic braking within a speed range of
between 4 mph (7 km/h) and 19 mph
(30 km/h).
In particular, the detection of obstacles can
be impaired if:
Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain
Rinterference by other radarsources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a

Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes"
section (Ypage 61).
ESP®monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP®detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP®assists the driver when
pulling away on wet or slippery roads. ESP®
can also stabilize the vehicle during braking.
ETS/4ETS (Electronic Traction System)
iObserve the "Important safety notes"
section (Ypage 61).
ETS/4ETS traction control is part of ESP®.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
if the road surface is slippery on one side. In
addition, more drive torque is transferred to
the wheel or wheels with traction.
ETS remains active when you deactivate
ESP®.
Important safety notes
GWARNING
If ESP®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP®checked at a
qualified specialist workshop.

active.
If ESP®intervenes, theESP®warning
lamp flashes in the instrument cluster.
If ESP®intervenes:
XDo not deactivate ESP®under any
circumstances.
XOnly depress the accelerator pedal as far
as necessary when pulling away.
XAdapt your driving style to suit the
prevailing road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. The engine starts
automatically when the driver wants to pull
away again. ESP®remains in its previously
selected status.Example:if ESP®was
deactivated before the enginewas switched
off, ESP®remains deactivated when the
engine is switched on again.

ESP®trailer stabilization
General information
If your vehicle/trailer combinationbegins to
swerve, ESP®assists you in this situation.
ESP®slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilized.
Important safety notes
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from
swerving.Trailers with a high center of gravity
can tip over before ESP®can detect this.
There is a risk of an accident.
Always adapt yourdriving style to the
prevailing road and weather conditions.
If yourvehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
ESP®trailer stabilization is active above
speeds of about 40 mph (65 km/h).
ESP®trailer stabilization does not work if
ESP®is deactivated or disabled because of a
malfunction.
EBD (electronic brake force
distribution)
General information
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
Important safety notes
iObserve the "Important safety notes"
section for driving safety systems
(Ypage 61).
GWARNING
If EBDhas malfunctioned, the rear wheels can
still lock, e.g.underfull braking.This
increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps (Ypage 242) as well as
display messages (Ypage 215).
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also has the HOLD function
(Ypage 172) and hill start assist
(Ypage 138). For further information, see
Driving tips (Ypage 158).
STEER CONTROL
General information
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering
wheel in the direction required for vehicle
stabilization.
This steering assistance is provided in
particular if:
Rboth right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
Rthe vehicle starts to skid.
Important safety notes
If ESP®is malfunctioning, you will not receive
steering support from STEER CONTROL.
Power steering will, however, continue to
function.
