ess is pre-emptive in nature as the airbag
must
be deployed during – and not at the end
of – the collision.
i Airbags are not deployed in all types of
accidents. They are controlled by complex
sensor technology and evaluation logic.
This process is pre-emptive in nature as
airbag deployment must take place during
the impact and must be adapted to provide
calculated, additional protection for the
vehicle occupants. Not all airbags are
deployed in an accident.
The different airbag systems work inde-
pendently of each other. However, the
deployment of each individual system will
depend on the type of accident determined
by the control system in the first stages of
the collision (head-on collision, side impact
and overturn) and the extent of the acci-
dent (in particular, the vehicle's rate of
deceleration or acceleration).
The rate of vehicle deceleration or accelera-
tion and the direction of the force are basi-
cally determined by:
R the distribution of forces during the colli-
sion
R the collision angle R
the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided, e.g. the other vehi-
cle
Factors which can only be seen and measured
after the collision has taken place do not play
a decisive role in the deployment of an airbag,
nor do they provide an indication of it.
The vehicle may be deformed significantly,
e. g. on the bonnet or the wing, without an
airbag being deployed. This happens if only
parts which are relatively easily deformed are
affected and the necessary deceleration does
not occur. Conversely, airbags may be
deployed even though the vehicle suffers only
minor deformations. This is the case if, for
example, very rigid vehicle parts such as lon-
gitudinal body members are affected and suf-
ficient deceleration occurs as a result.
Belt tensioners, belt force limiters The front seat belts and the outer seat belts
in

the rear are equipped with belt tensioners.
! Do not engage the seat belt tongue in the
buckle on the front-passenger seat if the
seat is not occupied. Otherwise the belt tensioner could be activated in an emer-
gency.
If the seat belt is also equipped with a belt
force limiter, the force exerted by the seat
belt on the seat occupant is reduced.
Belt tensioners tighten the seat belts in an
accident,

pulling them close against the body.
i Belt tensioners do not correct incorrect
seat positions or incorrectly fastened seat
belts.
Belt tensioners do not pull occupants back
towards the backrest.
The front belt force limiters are synchronised
with the front airbags, which spread the
forces exerted by the belt force limiters on
the occupant over a greater area.
When the ignition is switched on, the belt ten-
sioner is triggered:
R only if the restraint systems are operational
(the 1 warning lamp lights up after the
ignition is switched on and goes out once
the engine is running)(Y page 43)
R for each three-point seat belt in the front of
the vehicle when the belt tongue is
engaged in the buckle
R In the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler- Safety

Variable Speedtronic is deactivated automat-
ically when you depress the accelerator pedal
beyond the pressure point (kickdown). but
only if your current speed does not differ by
more than 20 km/h from the stored speed.
You will hear a warning tone if this is the case.
G
Risk of accident
It is not possible to deactivate variable
Speedtronic by braking.
i The last speed stored is cleared when you
switch off the engine.
Permanent Speedtronic i
Permanent Speedtronic is only available
for certain countries.
You can use the on-board computer to limit
the speed permanently to a value between
160 km/h (e.g. for driving with winter tyres)
and the maximum speed.
Shortly before the stored speed is reached, it
is shown in the multi-function display.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). Setting permanent Speedtronic

ter tyres). X
Press the æ orç button to select the

The following settings can be selected:
R Off
Permanent Speedtronic is deactivated.
R A limit speed between 240 km/h and
160 km/h in increments of 10 km/h.
X To select a different display, press j,
è or ÿ. HOLD
HOLD relieves the strain on the driver:
R when pulling away, especially on steep
slopes
R when manoeuvring on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is cancelled and HOLD
deactivated when you depress the accelera-
tor pedal to pull away.
Activation conditions You can activate HOLD if:
R
the vehicle is stationary
R the engine is running
R the driver's door is closed
R the parking brake is not applied
R the bonnet is closed
R the selector lever is in position D, R or N Controls

Activating HOLD X
Make sure that the activation conditions
are met.
X Depress the brake.
X Depress the brake again quickly until
HOLD appears in the display.
HOLD is activated. You can release the
brake pedal.
i If depressing the brake pedal the first
time does not activate HOLD, wait briefly
and then try again. G
Risk of accident
The vehicle's brakes are applied when
HOLD is activated. For this reason, deacti-
vate HOLD if the vehicle is to be set in
motion by other means (e.g. in a car wash
or by towing).
Deactivating HOLD HOLD is deactivated if:
R
you
accelerate when the selector lever is in
position D or R
R you move the selector lever to position P
R you release the brakes completely and
apply them again with a certain amount of pressure until the
HOLD message in the
multi-function display goes out G
Risk of accident
Never get out of the vehicle when HOLD is
activated.
HOLD

must never be operated or deactiva-
ted by a passenger or from outside the
vehicle.
HOLD does not replace the parking brake
and must not be used for parking.
The HOLD braking effect is cancelled and
the vehicle can start moving if:
R HOLD is deactivated by depressing the
accelerator pedal or the brake pedal
R there is a malfunction in the system or an
interruption in the power supply, e.g. bat-
tery failure
R the electrical system in the engine com-
partment, the battery or the fuses are
tampered with
R the battery is disconnected G
Risk of accident
If you wish to leave the vehicle or park it,
deactivate HOLD and secure the vehicle
against rolling away. You will see a warning message in the multi-
function display if HOLD is activated and:
R
the

driver's door is opened and you release
the seat belt
R the ignition is switched off
R the bonnet is opened
Selector lever in park position
X Move the selector lever to P
to prevent the
vehicle from rolling away.
HOLD is deactivated. The warning message
in the multi-function display goes out.
A horn will also sound at regular intervals if
HOLD is activated and you:
R stop

the engine and open the driver's door
R open the bonnet
The horn draws your attention to the fact that
the vehicle has been parked while HOLD is
still activated. The sound becomes louder if
you attempt to lock the vehicle. The vehicle
is not locked until HOLD is deactivated.
i If the ignition has been switched off, the
engine cannot be restarted until HOLD is
deactivated.
If there is a fault in the system or power supply
while HOLD is activated, the Brake immedi-
ately message appears in the multi-function Controls
