Characteristics of activated SPORT han-
dling mode
SPORT handling mode raises the intervention threshold for stabilizing the vehicle. This
allows for asportier driving style on desig-
nated race circuits and may in certain situa-
tions improve the traction in comparison with
ESP ®
.
If SPORT handling mode is activated and one or more wheels start to spin, the 0089warn-
ing lamp in the instrument cluster flashes.
ESP ®
only stabilizes the vehicle to alimited
degree.
When SPORT handling mode is activated:
R ESP ®
only improves driving stability to a
limited degree.
R traction control is still activated.
R ESP ®
still provides support when you brake
firmly.
R engine torque is only restricted to alimited
degree, and the drive wheels are able to
spin. The spinning wheels produce acut-
ting effect for better traction. Characteristics when ESP
®
is deactivated
If ESP ®
is deactivated and one or more wheels
start to spin, the 0089warning lamp in the
instrument cluster does not flash. In such sit-
uations, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning
of the wheels results in acutting action for
better traction.
R traction control is still activated.
R ESP ®
still provides support when you brake
firmly. EBD (electronic brake force distribu-
tion)
i Observe the "Important safety notes" sec-
tion (Y page 54).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
WARNING
If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapty our driving style
to the different handling characteristics. Have the brake system checked at aqualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 192) as well as dis-
play messages (Y page 166). ADAPTIVE BRAKE
