The stability system (ESC ) is always acti-
vated and cannot be switched off. However,
the driver can select ESC Sport Mode
which offers more active driving characteris-
tics.
With the ESC Sport Mode sub-function
selected, intervention from the system is
reduced and more lateral movement is permit-
ted, giving the driver more control of the vehi-
cle than usual.
When ESC Sport Mode is selected, the func-
tion may seem to be disabled even though it
continues to assist the driver.
NOTE
When ESC Sport Mode is selected, the
trailer stabilizer (TSA 7 ) is switched off.
ESC Sport Mode also helps provide more
traction, even if the vehicle gets stuck or is
driving on a loose surface such as deep snow
or loose sand.
