to the vehicle in front, for vehicle speed, braking
in good time and for staying in your lane. You are
always responsible for maintaining control over

Function of EBD (electronic brake
force distribution)
G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
EBD has the following functions:
R
monitoring and adjusting the braking pres-
sure distribution between the front and rear
wheels
R
improving driving stability when braking,
especially on bends

WARNING
If ESP
®
is malfunctioning it will not provide
any vehicle stabilisation. There is an
increased risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP
®
checked at a qualified specialist
workshop.
!
Do not operate the vehicle on a roller dyna-
mometer (e.g. for performance testing). If you
have to operate the vehicle on a roller dyna-
mometer, please consult a specialist work-
shop beforehand. You could otherwise dam-
age the drivetrain or the brake system.
ESP
®
monitors and improves driving stability
and traction especially in the following situa-
tions:
R
when pulling away on wet or slippery road
surfaces
R
when braking
R
vehicles with a trailer tow hitch: when tow-
ing a trailer from speeds of 60 km/h or above,
if the vehicle/trailer combination starts to
swerve
ESP
®
can stabilise the vehicle by performing the
following actions:
R
one or more wheels are braked.
R
engine output is adapted depending on the
situation.
ESP
®
is deactivated if the ESP
®
warning lamp
å
in the instrument cluster lights up contin-
uously:
R
driving stability is no longer improved.
R
the drive wheels may start to spin.
R
ETS traction control is no longer active.
R
vehicles with a trailer tow hitch: vehicle/
trailer combination stabilisation is no longer
active.
i
Even if ESP
®
is deactivated, ABS will still
support you when braking.
