Indicator and warning lamps

Technology that monitors itself

The system runs a check on the
warning and indicator lamps marked by
"

l

" each time you switch on the igni-
tion. 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.
The following section describes how
you should respond.

Red: stop immediately

Alternator charge current

l

The battery is no longer being
charged. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. Please
contact the nearest BMW center.
You should never attempt to
continue driving with a defective
drive belt, as the engine could overheat
and sustain serious damage. A defec-
tive drive belt will also make the vehicle
harder to steer.

<

Engine oil pressure



l


May be accompanied by the
warning "STOP!ENGINE
OILPRESS" in the Check Control
display panel: stop vehicle and switch
off engine immediately. Check level of
oil in engine, top up as required. If oil
level is correct: please contact the
nearest BMW center.
Stop at once. Attempts to
continue driving can lead to
serious engine damage stemming from
a lack of adequate lubrication.

l

Malfunction in DBC system.
Conventional braking performance
remains available with no loss of effi-
ciency.
Have the system repaired by your BMW
center at the earliest possible opportu-
nity.

Service Engine Soon

l
If the indicator lights up either
continuously or intermittently,
this indicates a fault in the emissions-
related electronic systems. Although
the vehicle remains operational, you
should have the systems checked at
your BMW center at the earliest
possible opportunity.

Parking brake Manual transmission The parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates at the rear
wheels.To engageThe lever engages automatically when
it is pulled up, and the "PARK BRAKE"
(in Canada "P") indicator lamp comes
on in the instrument cluster in ignition
key position 2. Refer to page 17. To releasePull up slightly on the lever, press the
button and lower the lever.390de714
If, in exceptional circumstances, it
should be necessary to engage
the parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling the lever up to apply
moderate pressure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear axle.
The brake lamps do not come on when
the parking brake is applied. Always
engage the parking brake when parking
on hills and inclined surfaces, as even
first gear or reverse may not provide
adequate resistance to rolling.<
You can help prevent corrosion and
maintain balanced braking by periodi-
cally pulling up the parking brake lever
gently while coasting to a stop at a
traffic light. Always check traffic condi-
tions first to avoid posing a hazard to
yourself or other road users.
When shifting gears, always depress
the clutch pedal all the way to the end
of its travel, then move the shift lever
until it engages securely in the desired
gear.
You will also need to depress the clutch
when starting the engine, as an auto-
matic lockout prevents the starter from
operating when the clutch is engaged.
When the vehicle lighting is switched
on, the shift pattern is illuminated on
the shift lever.
When shifting gears in the 5th/
6th-gear plane, be sure to press
the shift lever to the right in order to
prevent inadvertent selection of a gear
in the 3rd/4th-gear plane.<39mde017

Tachometer Engine oil temperature Fuel gauge During the warm-up period, the display
lamps in the orange caution zone indi-
cate the maximum recommended
engine speed for the current engine
temperature. As the engine warms to its
normal operating temperature, the
lamps in this adaptive display then go
out, one after the other.
Avoid allowing the engine speed to rise
into the caution zone.
Do not operate the engine with the
needle in the red overspeed zone of the
gauge.
To protect the engine, the engine-
management system interrupts the fuel
supply when you approach this sector.39mus023
The normal operating temperature
range is between + 176 7 (+ 80 6) and
+ 248 7 (+ 120 6). Do not exceed the
maximum temperature of +302 7
(+150 6). 39mus024
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
If the indicator lamp comes on and
stays on, there are approx. 2.5 gal
(10 liters) of fuel still in the tank.
For fuel tank capacity, refer to
page 143.
If the tilt of the vehicle varies (when you
are driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<39mus025

Coolant Brake fluidChecking coolant level and
adding coolantCorrect coolant level when the engine
is cold (approx. 68 7/20 6):
In the translucent container's visible
range, as far as the graduation marked
KALT/COLD.
1. Turn the cap counterclockwise
slightly in order to allow accumulated
pressure to escape
2. If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<39mde111
Brake fluid level
The warning lamp for the brake
system hydraulic circuits comes
on and/or the message "CHECK
BRAKE FLUID" appears in the
Check Control panel:
Brake fluid level too low.
To add brake fluidThe brake fluid reservoir is located
under the microfilter housing on the
driver's side of the vehicle. For adding
brake fluid or for determining and
correcting the cause of brake fluid loss,
consult your BMW center. Your BMW
center is familiar with the specifications
for factory-approved brake fluids
(DOT 4).
Brake fluid loss may result in extended
brake pedal travel. If this occurs, refer
to the information on page 108.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years at
a BMW center. Refer also to the Service
and Warranty Information Booklet (US
models) or the Warranty and Service
Guide Booklet (Canadian models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion which is out of reach of children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of brake fluid.<
