! é
The yellow ABS and
RBS warning lamps are
on while the drive sys-
tem is running.
ABS is temporarily unavailable. BAS, COLLISION PREVENTION
ASSIST, ESP
®
, EBD (electronic brake force distribution), the HOLD
function and hill start assist are therefore also deactivated, for
example.
Possible causes are:
R
Self-diagnosis is not yet complete.
R
The on-board voltage may be insufficient.
ATTENTION ASSIST is deactivated.
G WARNING
The braking performance of the electric motor using recuperative
braking may be either reduced or not effective. If you do not make
an additional effort to apply the brake yourself, the braking effect
may not be sufficient. If necessary, counteract the reduced regen-
erative braking effect by applying the brake yourself.
The brake system continues to function normally, but without the
functions listed above. The front and rear wheels could therefore
lock if you brake hard, for example.
The steerability and braking characteristics may be severely affec-
ted. The braking distance in an emergency braking situation can
increase.
If ESP
®
is not operational, ESP
®
is unable to stabilize the vehicle.
There is a risk of an accident.
X
Carefully drive a suitable distance, making slight steering move-
ments at a speed above 12 mph (20 km/h).
The functions mentioned above are available again when the
warning lamp goes out.
If the warning lamp is still on:
X
Observe the additional display messages in the multifunction
display.
X
Drive on carefully.
X
Visit a qualified specialist workshop.
