Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
by

the ignition key is turned. They each light up
once for different periods of time.
If a malfunction occurs in one of the monitored
systems, the corresponding lamp does not go
out after the engine has started, or it lights up
again while the vehicle is in motion. More infor-
mation can be found on the specified pages or
in the Owner's Manual for the BMW Z4 under
the respective terms.
Colors
The indicator and warning lamps can light up in
various colors and combinations.
>Red:
Stop the vehicle immediately
or

>Red and yellow:

Like fuel consumption, engine oil consumption
depends on your driving style and the vehicle's
operating conditions.
Warning lamp
Engine oil pressure
The warning lamp lights up in red:
The engine oil pressure is too low.
Stop the vehicle immediately and
switch off the engine. Check the engine oil level
and top up if necessary. If the oil level is correct,
please contact your nearest BMW Center or a
workshop that works according to BMW repair procedures with correspondingly trained per-
sonnel.
Do not continue driving, otherwise the
engine could sustain serious damage
from inadequate lubrication.<
Engine oil level
The warning lamp lights up in yellow
while you are driving. A signal also
sounds.
The oil level is at the absolute minimum; check
engine oil level using dipstick 7 and refill as
soon as possible. Do not drive more than
30 miles/50 km before refilling.
