Safety
Driving safety systems Braking
If ABS cuts in while you are braking, you
will feel:
!
the vehicle vibrating
! the brake pedal pulsating
This will indicate to you that ABS has been
acti vated. Always adapt your driving style
to suit the prevai ling road and weather
conditions.
6 Continue to depress the brake pedal,
even when ABS has been activ ated. Brake Assist operates
inemergency brak-
ing situation s.If you depress the brake
pedal quickly, BAS boosts the braking
force automatically and thus shortens the
stopping distance.
6 Depress the brake pedal firm lyuntil the
emergency-braking situation is ove r.
ABS prevents the wheels from locking.
When you release the brake pedal, the
brakes work as norm al again. BAS is then
deactivated. The Electronic Stabilit
y Program monitors
the traction, i.e. the power transmission
between the tyres and the road, and the
stability of the vehicle.
ESP detects when a wheel is spinning or
when the vehicle has begun to skid. ESP
stabilises the vehicle by applying specific
braking to individual wheels and limiting
the engine power output. ESP assists you
in particular when pulling away on a wet or
slip pery road surface.
If ESP cuts in, the vwarning lamp
flashes in the speedometer.
The v ESP warning lamp in the instru-
ment cluster lights up when you turn the
key to po sition 2in the ignition lock. It
goes out when the engine is running. This
ind icates that ESP is operational. G
Risk of accident Always adapt your driving style to suit the
prevailin
groad and weather conditions and
maintain a suffi cient distance from other
road users and objects onthe road. BAS
G
Risk of accident If BAS malfunctions, the brake system is still
available with the full brake boosting effect.
In an emer
gency braking situation, however,
th e braking fo rce is not automatically
bo osted and may lengthen the stopping dis-
tance. ESP209en_d2.boo Seite

! ESP only functions prop erly if whe els with
the recommended tyre sizes are used
( =
page 399).
The engine must not be running if:
! the parking brake is being teste dusing a
dynamometer
! the vehicle is being towed with the front axle
ra ised
Appli cation of the brakes by ESP may otherw ise
des troy the braking system on therear axl e. i
Only use wheels with the recommended tyre
si zes. Only then wil lESP function properly. Activating
/deactivating ESP
It may be best to deactivate ESP in the
following situations:
! if snow chains are being used
! in deep snow
! on sand or gra vel When you deactivate ESP:
! ESP no longer improves driving stability
! the engine's torque isthen no longer
limited and the drive wheels could spin.
This res ults in a cutting action ofthe
spinning wheels for better grip
! traction control is still activated
! you can still brake with support from
ESP
i Thev warning lamp in the instrument
clus ter flashes if ESP isdeactivated and one or
mor ewhe els start to spin. ESP doe snot then sta-
bil ise the vehic le. G
Risk of accident Proceed as follows if the
vwarning lamp
in the speedometer flashes:
! under no circumsta nces should you
de activate ESP
! onlydepress the accelerator pedal as
far as necessary when pulling away
! donot keep your foot onthe ac celerator
while you are driv ing
! adapt your driving sty leto suit the road
and weather conditions
Otherwise ,the vehicle could begin toskid.
ESP cannot reduce the risk of an accident if
you drive too fast. G
Riskofaccident Activate ESP as soon as th
esituations
described above no longer apply. ESP will
ot he rwi sebe unable to stabilise the vehicle
if the vehicle starts to skid or when a wheel
spins. 209en_d2.

Distronic assists you when driving on
motorways or high-speed ma jor roads.
! If a slower vehicle is detected ahead,
Distronic causes your vehicle to brake
and maintain a preset distance from
the vehicle infront.
! If there is no vehicle in front, Distronic
ope rates in the same way as cruise
control* ( =page 197). Distronic*
G
Risk ofinjury Do not place your foot und
erthe brake
pedal, as it coul dbecome trapped. Distronic
may apply the brakes to prevent the vehicle
fro mexceeding the setsp eed. When this
happens, Distronic depresses the brake
pedal. G
Risk of accident Distronic cannot take account
ofroad and
tra ffic conditions.
Always pay attent ion to road and traffic con-
di tions, even when Distronic is activated.
Distronic is onlyan aid desig ned to assist
you when driving. You are respon sible for
maintaining a suffi cient distanc efro mother
vehicles, for driv ing at anappropriate speed
an d for bra king in good time.
Do not activate Distronic:
! if road and traffic conditi onsdonot per-
mit a constant driving speed to be main-
tained (e.g .dense traffic or winding
ro ad s). You could otherwise causean
accident
! on slippery road surfaces. The drive
whe elsmay lose their grip when braking
or acceleratin gand the vehicle could
skid
! when visibility is bad, e.g. infog, heavy
rain or snow G
Risk of accident Deactivate Distronic:
!
when chan ging fro mthe outside lan eto
the inside lane if vehicles on the outside
la ne are travelling more slowly
! when driving in a filter lane or mot orway
exit
! when dri ving incomplex road and traffic
co nd ition s,such as throu ghmotorway

Otherwise, Dis tronic ma intains the stored
speed.
Distronic do esnot react:
! toas tationary obstacle, e.g. in a traffic
jam, or to a vehicle which has bro ken
do wn
! toan oncoming vehic lein the same lane
Distronic causes your vehicle to brake at a
maximum of 2 m/s2
. This is approximately
20% of the maximum braking force of your
vehicle. If this deceleration isinsufficient,
you will have to use the brake pedal to avoid
a collision. 209en_d2.boo Seite
