You are now again in normal driving
mode with ESP
® switched on.
iWhen the ESP® is switched off and one
or more drive wheels are spinning, the ESP®
warning lampv in the instrument cluster
flashes. However, the ESP
® will then not
stabilize the vehicle.
Warning!G
When the ESP® warning lampv is
illuminated continuously, the ESP® is
switched off or is not operational due to a
malfunction. Vehicle stability in standard
driving maneuvers reduces.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP
®.
!Avoid spinning of a drive wheel for an
extended period with the ESP® switched off. This
may cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.
