$J
òN$ (USA only) or J(Canada only): the ABS and brake warning lamps are
lit while the engine is running.
EBD is unavailable due to amalfunction .ABS ,BAS,h ill 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.
GWARNING
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 causes steerability and braking to be greatly impaired. The braking distance
can increase in emergency braking situations.
If ESP
®is not operational, ESP®will not stabilize the vehicle.
There is an increased risk of skidding and accidents.
XObserve the display messages.
XDrive on with care.
XVisit aqualified specialist workshop immediately.
