If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. This warning tone stops after
a maximum of six seconds or once the
driver's seat belt is fastened.
If after six seconds, the driver or front
passenger have not fastened their seat belts
and the doors are closed:
Rtheseat belt warning lamp remains lit
as long as the driver's or front-passenger's
seat belt is not fastened
and
Rif a vehicle speed of 15 mph (25 km/h) is
exceeded, theseat belt warning lamp
begins to flash.Awarning tone also sounds
with increasing intensity for a maximum of
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver/front passenger unfasten their
seat belt while the vehicle is in motion, the
seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases evenifthe driver or
front-passenger seat belt has still not been
fastened after 60 seconds. Theseat belt
warning lamp stops flashing but remains
illuminated.
After the vehicle comes to a standstill, the
warning tone is reactivated. Theseat
belt warning lamp flashes again if the vehicle
speed exceeds 15 mph (25 km/h).
Theseat belt warning lamp only goes
out if:
Rboth the driver and the front passenger
have fastened their seat belts.
or
Rthe vehicle is stationary and a door is open.
iFor more information on theseat
belt warning lamp, see "Warning and
indicator lamps in the instrument cluster,
seat belts" (Ypage 240).
Emergency Tensioning Devices, seat
belt force limiters
GWARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer
operational and are unable to perform their
intended protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency
Tensioning Devices which have been
triggered immediately replaced at a qualified
specialist workshop.
!If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the front-
passenger seat. Otherwise, the Emergency
Tensioning Device could be triggered in the
event of an accident.
The front seat belts and the outer seat belts
in the rear are equipped with Emergency
Tensioning Devices and seat belt force
limiter.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
The ETDs can only be activated when:
Rthe ignition is switched on.
Rthe restraint systems are operational; see
"SRS warning lamp" (Ypage 39).
Rthe belt tongue is engaged in the buckle on
each of the front seat belts.
The ETDs on the outside seats in the rear
compartmentare triggered independently of
the lock status of the seat belts.
The ETDs are triggered depending on the type
and severity of an accident:
Rif, in the event of a head-on or rear-end
collision, the vehicle decelerates or
accelerates rapidly in a longitudinal

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, the
symbol 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 thedistance 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.

section for driving safety systems

!When testing the electric parking brake
on a braking dynamometer, switch off the
ignition. Application of the brakes by
ESP®may otherwise destroy the brake
system.
!Vehicles with 4MATIC: switch off the
ignition when the electric parking brake is
being tested on a brake dynamometer.
Application of the brakes by ESP®may
otherwise destroy the brake system.
!Vehicles with 4MATIC: function or
performance tests may only be carried out
on a 2-axle dynamometer. Before you
operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage
the drive train or the brake system.
!Do not tow vehicles with 4MATIC with the
front or rear axle raised.
Vehicles without 4MATIC: when towing your
vehicle with the front axle raised, it is
important that you observe the notes on
ESP®(Ypage 307).
Vehicles with 4MATIC: when towing your
vehicle with both axles on the ground, it is
important that you observe the notes on
ESP®(Ypage 307).
ESP®is deactivated if theESP®OFF
warning lamp in the instrument cluster lights
up continuously when the engine is running.
If theESP®warning lamp and the
ESP®OFF warning lamp are lit
continuously, ESP®is not available due to a
malfunction.
Observe the information on warning lamps
(Ypage 244) and displaymessages which
may be shown in the instrument cluster
(Ypage 213).
iOnly use wheels with the recommended
tire sizes. Only then will ESP®function
properly.
Characteristics of ESP®
General information
If theESP warning lamp goes out before
beginning the journey, ESP®is automatically
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.

Side window reversing feature
The side windows are equipped with an
automatic reversing feature. If a solid object
blocks or restricts a side window during the
closing process, the side window opens again
automatically. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying
attentionwhen closing a side window.
