is deactivated, theå warning
lamp lights up continuously:
R Driving stability will no lon ger be impr oved.
R The drive wheels could spin.
R ETS/4ETS traction control is still active.
% When ESP ®
is deactivated, you are still assis‐

ETS/4ETS can impr ovetheve hicle's traction by
inter vening in thefo llowing ways:
R The drive wheels are braked individually if
they spin.
R More drive torque is transferred tothe wheel
or wheels with traction.
Influence of drive prog rams on ESP ®
