Indicator and warning lamps

Technology that monitors itself

Many of the systems for your BMW
monitor themselves automatically, both
during engine starts and while you are
driving. Indicator and warning lamps
identified by "

l

" are tested for proper
operation whenever the ignition key is
turned. They each light up once for
different periods of time.
The indicator lamps signal defects in
monitored systems either by remaining
lit after the engine is started or by
coming on in the course of normal
vehicle operation. Refer to the following
section for detailed information on how
to respond to the various types of warn-
ings.

Red: stop immediately

Battery charge current
The alternator is no longer
charging the battery. Indicates a
defect in the alternator drive belt or the
charging circuit. Please contact the
nearest BMW center.
Never attempt to continue driving
if the V-belt is defective: the
engine could overheat and sustain
serious damage. A broken or damaged
V-belt will also lead to a sudden
increase in steering effort.

<

Engine oil pressure

l

Stop vehicle and switch off
engine immediately. 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. The
engine could sustain damage
owing to inadequate lubrication.

Tire Pressure Warning (RDW)

l

Flashing warning lamp in addi-
tion to an acoustic signal: a tire
failure has occurred. Carefully reduce
speed to less than 50 mph (80 km/h),
and avoid hard braking or steering
maneuvers.
For additional information, refer to
page 67.
Brake warning lamp

(DSC) l
Indicator lamp flashes:
The system is actively regulating engine
torque.
If the indicator lamp does not go out
after the engine is started, or if it comes
on during normal driving and stays on:
DSC has been switched off or has been
deactivated because of a malfunction.
In the event of a malfunction, have the
system checked by your BMW center.
For additional information, refer to
page 65.
Service Engine Soon l
If the indicator lamp comes on
either continuously or intermit-
tently, this indicates a fault in the emis-
sions-related electronic systems.
Although the vehicle remains opera-
tional, you should have the systems
checked by your BMW center at the
earliest possible opportunity.
For additional information, refer to
page 124.

Engine electronics
Malfunction in the engine's
electronic control system. The
electronics revert to a default mode
permitting continued operation, but at
lower than usual engine speeds and
with reduced power. Please have the
system inspected by your BMW center.

Tire Pressure Warning (RDW)The conceptRDW monitors the tire pressure in all
four wheels while driving. The system
provides an alert whenever the inflation
pressure drops significantly in one of
the tires.
For RDW to "learn" the correct tire infla-
tion pressure, check the inflation pres-
sure in all tires, comparing them with
the values in the inflation pressure table
(refer to page 27), and make correc-
tions as necessary. Then activate the
system.
The indicator lamp within the in-
strument cluster flashes to alert
you to substantial pressure loss
in any of the tires.
To activate the system 1 Turn the ignition key to position 2
2 Press the switch long enough for
the indicator lamp in the instrument
cluster to light up red for a few
seconds
3 RDW carries out an automatic
initialization process while you are
driving, and stores this data to aim for
optimal conditions. This one-time
"learning" process lasts at least
10 minutes, after which the RDW is
able to detect and report a flat tire.520de117
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement.
Do not reactivate the system after
periodic corrections of inflation pres-
sures to maintain them at the levels
stored during an earlier initialization
process.

Side lamps (Side marker lamps)
With the switch in this position,
the front, rear and side vehicle
lighting is switched on.
When leaving the vehicle parked, you
also have the additional option of acti-
vating the lighting on just one side, refer
to page 70.
Low beam headlamps
When you switch off the ignition
and the low beams are still on,
only the side lamps (side marker
lamps) remain on.

"Follow-me-home lighting":
If you actuate the headlamp
flasher after you have parked the
vehicle and shut off the engine, the low
beams will remain on for a brief period.
You may also have this function deacti-
vated if you wish.<
"LAMPS ON" warningIf you turn the ignition key to position 0,
an acoustic signal will sound for a few
seconds after the driver's door has
been opened if the low beam head-
lamps have not been switched off.Daytime running lamps

The headlamps are automatically
switched on for daylight driving when
ignition key is in position 2.

Disc brakes Brake systemDriving notesWhen driving in heavy rain and on wet
roads it is advisable to apply light pres-
sure to the brake pedal every few miles.
Monitor traffic conditions to ensure that
this maneuver does not pose a hazard
to you or to other road users. The heat
generated in this braking process helps
dry the pads and rotors.
Maximum braking force is obtained
while the wheels are not locked, but
rather when they are still barely turning
immediately prior to locking. ABS main-
tains this state automatically. If the ABS
fails, you should revert to the staggered
braking technique (refer to page 93).
When descending steep hills and
extended grades, downshift to a gear
that will allow you to continue safely
with only a minimal amount of braking.
By minimizing the loads placed on the
brake system, this strategy helps
ensure that optimal brake system
response will remain available at all
times.
You can enhance the engine's braking
effect by engaging a lower gear, down-
shifting as far as first gear when
descending extremely steep slopes. Even if engine braking fails to slow the
vehicle sufficiently, you should still
make every effort to avoid prolonged
braking with continuous application of
low to moderate pressure at the pedal.
It is better to decelerate the vehicle by
applying a higher level of force at the
pedal (watch following traffic!) and then
subsequently pausing to allow the
brakes to cool briefly before starting on
your next braking cycle. By protecting
brake system components against
overheating, the cooling phases
afforded by this staggered, or intermit-
tent braking technique help maintain
consistent availability of optimal braking
response when it is needed.
Do not coast with the clutch
depressed, the gear-shift lever in
neutral, or, above all, with the engine
off; otherwise, the engine will provide
no braking effect if the transmission is
in neutral, and there is no braking or
steering power assist if the engine is
not running. Never allow floor mats,
carpets or any other objects to obstruct
the accelerator, clutch or brake pedals
and pose a safety hazard by reducing
their available travel range.<
Brake fluid level
The brake warning lamp comes
on with the parking brake
released:
The brake fluid level in the reser-
voir is too low, refer to page 112.
If the brake fluid level is too low
and brake pedal travel has become
noticeably longer, there may be a
defect in one of the brake system's
hydraulic circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<

Coolant Brake fluidAdding coolant To guard against the possibility of
scalding injuries, always wait until the
engine cools (temperature gauge
needle in blue sector) before
unscrewing the cap on the expansion
tank.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape, then continue
turning to remove.
2 If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the
prescribed all-season 50:50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant every three years.The brake warning lamp comes on and
the parking brake has been released:
Check the brake fluid level. Fill it to the
top mark ("MAX") if necessary.
For adding brake fluid or for deter-
mining 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 can increase brake
pedal travel. For this type of situation,
refer to the notes on page 91.
520de157
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 by
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 attacks the
vehicle's paintwork. You should always
store it in its original container and in a
location that is inaccessible to 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.<
