The windowbags are integrated into the side
of the roo
fframe and deploy in the area
extending from the front door (A-pillar) to the
rear door (C-pillar). Windowbags
:are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate

PRE-SAFE ®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R in emergency braking situations, e.g. if BAS
is activated or intervenes powerfully in vehicles with DISTRONIC PLUS, BAS PLUS
or PRE-SAFE ®
Brake
R if the radar sensor system detects an immi-
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
R in critical situations involving driving
dynamics, e.g. if the vehicle oversteers or
understeers significantly due to physical
limits being exceeded or if the vehicle
swerves to avoid an obstacle at a speed of
over 140 km/h.
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memory function: under
accident conditions, it adjusts the front-
passenger seat if it is in an unfavourable
position.
R vehicles with a multicontour seat or an
active multicontour seat: the air pressure
in the side bolsters on the seat cushion and
the side bolsters on the backrest is
increased.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroof and the side win-
dows are closed so that only a small gap
remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat/active
multicontour seat is reduced again. All set-
tings made by PRE-SAFE ®
can then be
reversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism releases. G

Risk of accident
The risk of an accident is significantly
increased by driving too fast. This is particu-
larly 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 can neither reduce this risk nor over-
ride the laws of physics.
For this reason, always adapty our driving
style to the prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road.
i In wintry driving conditions, always use
winter tyres (M+S tyres) and if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. 56
Driving safety systemsSafety

ABS (Anti-lock Braking System)
Important safety guidelines G
Ris
kofa ccident
Do no tdepress the brake pedal several times
in quick succession (pumping). Pumping the
brake pedal reduces the braking effect. You
might otherwise not be able to stop the vehi-
cle in time and could cause an accident.
Depress the brake pedal firmly and smoothly.
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.
Braking If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
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 vehi-
cle when braking and the braking distance
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 condi-
tions.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func-
tions as a reminder to take extra care while
driving. 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 system
remains available with full brake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase. BAS PLUS (Brake Assist PLUS)
BAS PLUS is only available in vehicles with
DISTRONIC PLUS.
BAS PLUS assists you in braking during haz-
ardous situations at speeds above 30 km/h
and uses the radar sensor system to evaluate
the traffic situation. G
Risk of accident
BAS PLUS is only an aid to assist you when
driving. You are responsible for maintaining a
safe distance from other vehicles, for the vehi-
cle's speed and for braking in good time.
Always pay attention to the traffic conditions.
Otherwise, you may recognise dangers too
late, cause an accident and injure yourself
and others.
BAS PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time. Should you approach a detected obsta-
cle quickly, BAS PLUS calculates the braking
force necessary to avoid a rear-end collision.
Should you additionally apply the brakes, BAS
PLUS will automatically increase the braking Driving safety systems
57Safety Z

force to a level suitable for the traffic condi-
tions.
If BAS PLUS demands particularly high brak-
ing force, PRE-SAFE
®
is activated simultane-
ously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if:
R you release the brake pedal.
R no obstacle is detected in front of your
vehicle.
R there is no longe rany dange rofarear-end
collision.
BAS PLUS is then deactivated.
At speeds up to approximately 70 km/h, BAS
PLUS may also detect stationary obstacles,
for example, stopped or parked vehicles.
Vehicles without COMAND and a navigation
system and vehicles for Australia: the radar
sensor system and on-board computer must
be switched off in the vicinity of radio tele-
scope facilities (Y page 210).
For BAS PLUS to assist you when driving, the
rada rsensor system must be switched on and
operational. You can chec kthis by activating
DISTRONIC PLUS(Y page 154) or via the
"radars ensor" function in the on-board com-
puter (Y page 210). G
Risk of accident
Only clearly identified obstacles will initiate
braking assistance by BAS PLUS.
In particular, the detection of obstacles can
be restricted if there is:
R dirt on the sensors or anything else cover-
ing the sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example in
multi-storey car parks
BAS PLUS does not react to people or ani-
mals, oncoming vehicles and crossing traffic,
or when cornering. BAS PLUS may not detect narrow vehicles
such as motorcycles and vehicles driving on
a different line.
Following a collision or accident-related dam-
age to the fron tend of the vehicle, have the
configuratio nand operatio nofthe radar sen-
sors checked at a Mercedes-Benz Service
Centre.
If BAS PLUS is not available due to a malfunc-
tion in the radar sensor system, the brake
system remains available with full brake
boosting effect and BAS. 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
or BAS PLUS, 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 .Ifthe
brakes are applied again, the brake lamps
light up continuously.T he hazard warning
lamps switch off automatically if you travel
faster than 10 km/h .You can also switch off
the hazard warning lamps using the hazard
warning switch button . ESP
®
(Electronic Stability Program)
Important safety notes 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. If necessary, 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 slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking. 58
Driving safety systemsSafety

If ESP
®
intervenes, the ÷warning lamp
flashes in the instrument cluster. G
Risk of accident
If the ÷ warning lamp in the instrument
cluster flashes, proceed as follows:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt yourd riving style to suitt he prevail-
ing road and weather conditions.
Otherwise, the vehicle could go into a skid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! Switch the ignition off when:
R the parking brake is being tested using a
dynamometer
R the vehicle is being towed with the front/
rear axle raised
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
! Do not tow vehicles with 4MATIC with the
front or rear axle raised.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS/4ETS (Electronic Traction System) Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually 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. On vehicles with 4MATIC, more drive
torque is also transferred to the wheel or
wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
. G
Risk of accident
Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics.
Deactivating/activating ESP ®
(except
AMG vehicles) ESP
®
is activated automatically when the
engine is started.
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.E SP®
will
otherwise not be able to stabilise the vehicle
if the vehicle starts to skid or a wheel starts
to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides bette rgrip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ESP®
warning lamp in
the instrument cluster flashes. In such situa-
tions, ESP ®
will not stabilise the vehicle.

ESP
®
is activated automatically when the
engine is started.
It may be best to activate SPORT handling
mode in the following situations:
R when using snow chains
R in deep snow
R on sand or gravel
Otherwise, you should only use SPORT han-
dling mode on designated race circuits. G
Risk of accident
Deactivate SPORT handling mode and acti-
vate ESP ®
as soon as the situations described
above no longer apply. Otherwise, SPORT
handling mode will only be able to stabilise
the vehicle to a limited degree if the vehicle
starts to skid or a wheel starts to spin.
When SPORT handling mode is activated:
R ESP ®
only improves driving stability to a
limited degree.
R the engine's torque is restricted to a limited
degree and the drive wheels can spin. The
spinning of the wheels results in a cutting
action, which provides better grip. R

EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
Risk of accident
If EBD has malfunctioned, the braking system
remains available with full brake boosting
effect .However, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident .You should therefore adapt your
driving style to the different handling charac-
teristics. ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (Y page 165) and
hill start assist (Y page 131). For further
information, see Driving tips (Y page 149). PRE-SAFE
