Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started or
it lights up while the vehicle is moving.
You will see how to react to this below.

Red: stop immediately

Battery charge current

●

The battery is no longer being
charged. There is a malfunction
of the alternator drive belt or in the
charging circuit of the alternator. please
contact the nearest BMW center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

<

Engine oil pressure

●

An alarm sounds at the same
time. Stop vehicle immediately
and switch off engine. Check the
engine oil level and top up as required.
If the oil level is correct, please contact
the nearest BMW center.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

<

Flat Tire Monitor

●

In addition, an acoustic signal is
sounded: a tire failure has
occurred. To come to an immediate
stop, reduce speed, while avoiding any
sudden, jerky braking or steering
maneuvers.

Indicator lamp
The transmission indicator lamp
in the instrument cluster goes
out after the engine is started.
>If it does not go out, or if it lights up
during driving, a fault has occurred.
The available functions may be lim-
ited under certain circumstances.
Drive carefully and with the Dynamic
Stability Control (DSC) activated.
Have the system checked by the
nearest BMW center
>If the indicator lamp flashes while
driving, the system is overloaded.
Avoid high loads until the indicator
lamp goes out again permanently.
Shift lightsTo achieve the best possible vehicle
acceleration with a sporty driving style
in the sequential mode, shift lights in
the instrument cluster indicate the opti-
mum shifting point shortly before the
maximum engine speed is reached.
1. When the maximum engine speed is
approached, yellow indicator fields,
shift lights, in the tachometer light up
consecutively to indicate the
approaching upshift time
2. Shift at the latest when the last indi-
cator field lights up red.
Tire replacement, snow chainsFollowing a tire or wheel change and
after mounting or removing snow
chains, the slip recognition of the
SMG II must become familiar with the
changed condition.
Reinitialize the system afterwards:
1. Move the selector lever into
position 0 on a straight stretch of
road at a speed of over 20 mph /
30 km/h
2. Pull both shift paddles for approx.
two seconds.
If you do not carry out the initialization,
the system automatically learns the
changed condition gradually during
driving. This can become apparent due
to brief opening and closing of the
clutch.

Fuel gaugeOnce the indicator lamp stays on con-
tinuously, there are still approx.
2 gallons/8 liters of fuel in the fuel tank.
Fuel tank capacity approx. 16.6 gal./
63 liters.
If the tilt of the vehicle varies – when
you are driving in mountainous areas,
for example – the needle may fluctuate
slightly.
Fill the fuel tank before it is com-
pletely empty. Driving to the last
drop of fuel can prevent the engine
from operating properly and result in
damage.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
Engine coolant temperature gaugeBlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly as an
operation check.
If the lamp comes on while operating
the vehicle: the engine has overheated.
Switch off the engine immediately and
allow it to cool down.
To check the coolant level, refer to
page 126.
Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector during normal operation.

However, if the vehicle is exposed to
temperatures below –47 /–206 for
extended periods, please have your
BMW center recommend a suitable oil.
Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their closed origi-
nal containers and in a location inac-
cessible to children. Antifreeze and
anti-corrosion agents are inflammable.
For this reason, do not spill them on hot
engine parts. They could ignite and
cause burns. Comply with the instruc-
tions on the containers.<
Check the coolant level and add
coolant Check the coolant level when the
engine is cold, approx. 687/+206.
1. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape. Then open
2. The coolant level is correct when the
upper end of the red float is at least
even with the upper edge of the filler
neck – refer to the arrow in the illus-
tration – but no more than 3/4 in/
2 cm above it – that is, up to the sec-
ond mark on the float. Refer also to
the schematic diagram next to the
filler neck
