Check Control

System malfunctions are shown in plain
text, and a gong warning sounded.
There is also a general warning light on
the instrument panel which comes on
during the journey if a fault signal is
present.
1 Symbol that a warning is present
2 Display
3 Plus sign for further fault displays
4 CHECK button
A system of 3 priority categories has
been adopted for the fault signals:
Priority 1
These faults are shown immediately
with a gong signal and flashing indica-
tion in the display (1). If several faults
develop simultaneously, they are dis-
played in succession. These displays
remain active until the fault is rectified,
and cannot be cleared with the CHECK
button (4).
d "HANDBRAKE ON"
This signal appears shortly after the car
has begun to move.
d "BRAKE ASSIST INACT."
The driver may have to exert extra
effort when steering and braking,
since the brake servo pressure is lost
and the power assistance for the
steering is also out of action. See
Page 103.
d "BRAKE LIGHT CIRCUIT"
The brake lights are not working. The
fuse has blown or the circuit is inter-
rupted. See Page 106, or consult
BMW Service.
d "BRAKE LIGHTS FAILURE"
The brake lights themselves have
failed – the bulbs have blown.
Renew defective bulbs. See Page
119.
d "LOW BRAKE FLUID"
The level is close to the minimum
mark. Top up at the earliest opportu-
nity. See Page 99. Have the cause of
the brake fluid loss rectified by BMW
Service.
d "ENGINE OILPRESS LOW"
Engine oil pressure has dropped too
low. Stop the car immediately and
switch off the engine. See Page 16.
d "COOLANT TEMPERATURE"
The temperature is too high. Stop the
car immediately and switch off the
engine. See Pages 19, 100.
