When towing the vehicle with the rear axle
raised, observe the notes on ESP®
(Ypage 257).
If the å ESP®OFF warning lamp lights up
continuously, then ESP®is deactivated.
If the ÷ ESP®warning lamp and the å
ESP®OFF warning lamp are lit continuously,
ESP®is not available due to amalfunction.
Observe the information on warning lamps
(
Ypage 205) and display messages which may
be shown in the instrument cluster
(
Ypage 179).
iOnly use wheels with the recommended tire
sizes. Only then will ESP®function properly.
Characteristics of ESP®
General information
If the ÷ ESP®warning lamp goes out before
beginnin gthe journey, ESP®is automatically
active.
If ESP
®intervenes, the ÷ESP®warning lamp
flashes in the instrument cluster.
If ESP
®intervenes:
XDo not deactivat eESP®under any circum-
stances.
XOnly depress the accelerator pedal as far as
