Electronic Stability Control in sport
mode
The stability system (ESC
6
) is always activated –
it cannot be switched off. However, the driver
can select
ESC Sport Mode, which allows for a
more active driving experience.
With the ESC Sport Mode subfunction
selected, intervention from the system is reduced
and the car is allowed to skid more and greater
control than normal is thus transferred to the
driver.
When
ESC Sport Mode is selected, the func-
tion can be considered as deactivated, despite
the function continuing to help the driver in many
cases.
NOTE
With ESC Sport Mode selected, Trailer Sta-
bility Assist (TSA
7
) is deactivated.
ESC Sport Mode also provides maximum trac-
tion if the car has become bogged down or is
driving on a loose surface, such as in sand or
deep snow.
