Indicator and warning lamps

Technology that monitors itself

Many of the systems of your BMW mon-
itor themselves automatically, both dur-
ing engine starts and while you are driv-
ing. Indicator and warning lamps that
are identified by "

l

" are tested for
proper functioning whenever the igni-
tion key is turned. They each light up
once for different 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



l


The battery is no longer being
charged. There is a malfunction
of the alternator ribbed V-belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
If the ribbed V-belt is defective, do
not continue driving. The engine
could be damaged due to overheating.
If the ribbed V-belt is defective, in-
creased steering effort is also re-
quired.

<

Engine oil pressure


l


Stop vehicle and switch off en-
gine immediately. Check level of
oil in engine, top up as required. If oil
level is correct: Please contact the
nearest BMW center.
Do not continue driving. The en-
gine could be damaged because
of inadequate lubrication.

In addition, there is an acousti-
cal warning signal: A tire failure
has occurred. Reduce vehicle speed
immediately and stop the vehicle. Avoid
hard brake applications. Do not over-
steer.
For additional information: Refer to
page 82.

If the lamp comes on when the
parking brake is not engaged:
Check the brake fluid level. Before driv-
ing further, be sure to read the notes on
pages 109 and 127.

Fuel gauge Temperature gauge When you switch on the ignition, the
indicator lamp comes on briefly to con-
firm that the system is operational.
Once the indicator lamp begins to light
up continuously, there are still approx.
2.1 gallons (8 liters) of fuel in the fuel
tank.
Tank capacity: page 173.
If the tilt of the vehicle varies, e.g.,
when you are driving in mountainous
areas, this may cause the needle to
fluctuate slightly.
Please refuel early, as driving to
the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<462us020

ate engine and vehicle speeds.RedWhen you switch on the ignition, the
indicator lamp comes on briefly to con-
firm that the system is operational.
If the lamp comes on while operating
the vehicle, the engine is overheated.
Switch the engine off immediately and
allow it to cool down.460de082

usual for the needle to rise as far as the
edge of the red zone in response to high
outside temperatures or severe operat-
ing conditions.

Clothes hooks:
When suspending clothing from the
hooks, ensure that they will not obstruct
the driver's vision. In order to avoid per-
sonal injuries during braking maneu-
vers, do not hang heavy objects on the
hooks. exhaust emissions, and is designed for
use with unleaded fuel only.
Even minute quantities of lead would be
enough to permanently damage both
the catalytic converter and the system
oxygen sensor.
To ensure efficient, trouble-free engine
operation and avoid potential damage:
>Be sure to comply with the scheduled
maintenance requirements
>Do not drive until the fuel tank is
empty
>Tow-start only when the engine is
cold, otherwise unburned, residual
fuel in the catalytic converter could
ignite and cause damage. It is better
to start the vehicle with an outside
starting aid
>Avoid other situations in which the
fuel is not burned, or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine that is running
properly does not present a problem).
Never let the engine run with any of
the spark plug cables disconnected.Be sure to comply with the in-
structions above to prevent un-
burned fuel from reaching the catalytic
converter. Otherwise, the catalytic con-
verter could respond by overheating,
leading to serious damage.
Extreme temperatures occur at the cat-
alytic converter. Heat shields are in-
stalled adjacent to some sections of the
exhaust system. Never remove these
shields; do not apply undercoating to
their surfaces. When driving, standing
at idle, and parking the vehicle, take
care to avoid contact between the ex-
haust system and flammable materials
(grass, hay, leaves, etc.). Such contact
could lead to a fire, resulting in serious
injury and property damage.
