Occupant safety

Sidebags
1and 2are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or accelera-
tion, e.g. in a side impact
R independently of seat belt use
R independently of the front airbags
R independently of the belt tensioners
R if the vehicle overturns, but only if the sys-
tem detects high vehicle deceleration in a
lateral direction and determines that side-
bag deployment can offer additional pro-
tection to that provided by the seat belt
Windowbags
The purpose of the windowbags is to enhance
the level of protection for the head (but not
chest or arms) of the vehicle occupants on
the side of the vehicle on which the impact
occurs.
The windowbags are integrated into the side
of the roof frame and run from the front door
(A-pillar) to the rear door (C-pillar). Saloon shown as an example
1 Windowbag
Windowbags 1are deployed:
R at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
lateral direction
R on the side on which an impact occurs
R independently of the front airbags
R regardless of whether the front-passenger
seat is occupied
R if the vehicle overturns and the system
determines that windowbag deployment
can offer additional protection to that pro-
vided by the seat belt PRE-SAFE
®
system
PRE-SAFE ®
system takes pre-emptive meas-
ures to protect you in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes in the event of:
R emergency braking situations, e.g. if BAS
Brake Assist intervenes
R critical situations involving driving dynam-
ics, e.g. if the vehicle oversteers or under-
steers significantly due to physical limits
being exceeded
If you are driving faster than approximately
30 km/h, PRE-SAFE ®
takes the following
measures in the aforementioned situations:
R It tensions the front seat belts.
R Vehicles with memory functions*: it
adjusts the front-passenger seat if this is in
an unfavourable position.
R If the vehicle skids, it closes the sliding/
tilting sunroof* and side windows so that
only a small gap remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
releases
the belt pretensioning. You can then reverse
all settings made by PRE-SAFE ®
again. Safety

Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock Braking System)
R BAS ( Brake Assist System)
R Adaptive brake lamps
R ESP ®
( Electronic Stability Program)
R EBV (electronic brake-power distribution)
R ADAPTIVE BRAKE
i In wintry road conditions, always use win-
ter tyres (M+S tyres) and, where necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. G
Risk of accident
The risk of an accident is significantly
increased by driving too fast. This is partic-
ularly the case when cornering as well as
on wet or slippery roads or when driving too
close to the vehicle in front.
The driving safety systems described in this
section cannot reduce this risk nor override
the laws of physics. For this reason, always adapt your driving
style to suit the prevailing road and weather
conditions. Maintain sufficient distance
from other road users and objects on the
road.
ABS (Anti-lock Braking System)
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from a speed of about 8 km/h
upwards, regardless of road surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently. G
Risk of accident
Do not depress the brake pedal several
times in quick succession (pumping).
Depress the brake firmly and evenly. Pump-
ing the brake pedal reduces the braking
effect.
Braking If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.Safety

X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force. G
Risk of accident
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the
vehicle when braking and the braking dis-
tance may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are also deactivated.
There is an increased risk of your vehicle
skidding in certain situations.
You should always adapt your driving style
to suit the prevailing road and weather con-
ditions. BAS (Brake Assist)
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep 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. G
Risk of accident
If BAS has malfunctioned, the braking sys-
tem remains available with full brake boost-
ing effect. However, braking force is not
automatically increased in emergency
braking situations and the stopping dis-
tance may increase. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by BAS,
the brake lamps flash rapidly. In this way,
traffic travelling behind you is warned in an
even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you drive
faster than 10 km/h again. You can also
switch off the hazard warning lamps using the
hazard warning switch button (Y page 102). Safety

Driving safety sys
tems60 ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between the tyres
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 stabilise the
vehicle. The engine output is also modified, if
necessary, to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
When ESP ®
intervenes, the vwarning
lamp flashes in the instrument cluster. G
Risk of accident
If the v warning lamp in the instrument
cluster flashes, proceed as follows:
R Do not deactivate ESP ®
under any cir-
cumstances.
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Adapt your driving style to suit the pre-
vailing road and weather conditions.
The vehicle could otherwise go into a skid. ESP
®
cannot reduce the risk of an accident
if you drive too fast. ESP ®
cannot override
the laws of physics.
! If the vehicle is to be towed with the front
or rear axle raised, the ignition must be
switched off (key in position 0or 1in the
ignition lock). Application of the brakes by
ESP ®
could otherwise destroy the brake
system on the front or rear axle.
! Vehicles with 4MATIC* may not be towed
with the front or rear axle raised.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
Deactivating/activating ESP ® ESP
®
is activated automatically when the
engine is running.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehi-
cle if the vehicle starts to skid or a wheel
starts to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels produce a cutting effect for better
traction.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
i If ESP ®
is deactivated and one or more
wheels start to spin, the vwarning lamp
in the instrument cluster flashes. In such
situations ESP ®
will not stabilise the vehi-
cle. Safety
