Introduction
General notes Display messages appear in the multifunction display.
Display messages with graphic displays may be shown in simplified form in the Operator's
Manual and may therefore differ from the multifunction display.
Please respond in accordance with the display messages and follow the additional notes in this Operator's Manual.
Certain display messages are accompanied by an audible warning tone or a continuous tone.
When the ignition is switched off, all display messages are deleted, apart from some high-
priority display messages. Once the causes of the high-priority display messages have been
rectified, the corresponding display messages are also deleted.
When you stop and park the vehicle, please observe the notes on:
R HOLD function (Y page 163)
R Parking (Y page 153)
Hiding display messages X
Press the aor% button on the steering wheel to hide the display message.
The display message is cleared.
The multifunction display shows high-priority display messages in red. Some high-priority dis- play messages cannot be hidden.
The multifunction display shows these messages continuously until the causes for the mes-
sages have been remedied.
Message memory The on-board computer saves certain display messages in the
message memory. You can call
up the display messages:

Possible causes are:
R self-diagnosis is not yet complete.

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 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 an increased risk of skidding and an accident.
