The ABS and brake system warning lamps light up while the engine is running.
EBD is unavailable due to a malfunction. ABS, BAS, hill start assist and ESP
®
as well
as its driving safety systems, for example, are therefore also unavailable.
ATTENTION ASSIST is deactivated and other driving systems could be automati-
cally deactivated.
G
WARNING
The brake system continues to function normally, but without the functions listed
above. The wheels could therefore lock prematurely if you brake hard, for example.
This greatly impairs steerability and braking. The braking distance can increase in
emergency braking situations.
If ESP
®
is not operational, ESP
®
will not stabilise the vehicle.
There is an increased risk of skidding and accidents.
X
Switch the engine off, wait briefly and start the engine again.
X
Check if the display message has disappeared and ESP
®
is operational.
