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

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.
