Driving safety
systems
In this section, you will find information
about the following driving safety system s:
! ABS(A nti-lock B raking S ystem)
! BAS (B rake As sist)
! ESP (E lectronic S tability P rogram)
i In wintry conditions, use winter tyres (M+S
tyres), with snow chains if ne cessary. The maxi-
mu m effect of ABS, BAS, ESP and SBC can only
be ac hievedin this way. ABS regulates the brake
pressure insuch a
way that the wheels do not lock when you
brake. This allows you to continue steer-
ing.
ABS works from a speed of approxi mately
8 km /hupwards, regardless of road sur-
face conditions.
ABS works on slip pery road surfaces, even
when you only brake gent ly.
The - indicator lamp in the instrument
cluster ( =page 12 )light s up when you
turn the keyto position 2in the ignition
lock. It goes out when the engine isrun-
ning. This indicates that ABS is opera-
tional. Dr
iving safety systems G
Risk of accident The risk of an acci
dent increases especially if
you:
! drive too fast, particularly when cornering
and ona wet or slippery road surfa ce
! drive too close to th evehicle in front
The driving safety systems described in this
section are unable to reduce this risk or over-
ride the laws of physics.
For this reason, always adapt your driving
style to suit the current road and weather con-
ditions and maintain asuffici en tdistanc efrom
other road users and objectsonthe road. ABS
G
Risk of accident Do not depress the brake pedal several times
in
qu ick succession (pumping). Depress the
brake firmly and evenly .Pumping the brake
ped alreduces the braking effect. 209en_d2.boo Seite

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.

i You can also use the KEYLESS GO key just
like a normal key with remote control
(= page 78).
If th e vehicle has beenparked upfor a long

ints to bear in mind
! Always carry the KEYLESS GO key on
your person.
! Never store the KEYLESS GO key
toge ther with:
! electronic equipment, e.g. a mobile
phone
! met allic objects such as coins or
foil
This could otherw ise impair the key's
effectiven ess.
! To lock or unlock the vehicle using the
KEYLES SGO key, the key must be out-
side the vehicle and no more than a
metre away fro mthe door or boot.
! To start the engine with the KEYLESS
GO button on the selector lever:
!the KE YLES SGO ke ymu stbe inthe

and the selector lever is at P(vehi-
cles with automatic transmission*)
The key in the ignition lock then
has priority over the KEYLESS GO
function and the vehicle electrical
system will be controlled in accord-
ance with the position of the key in
the ignition lock.
