Indicator and warning lamps

Technology that monitors itself

Many of the systems of your BMW
monitor themselves automatically, both
during engine starts and while you are
driving. 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 will light up while the vehicle is mov-
ing. You will see how to react to this
below.

Red: stop immediately

Battery charge

l
The battery is no longer being
charged. There is a malfunction
of the alternator V-belt or in the charg-
ing circuit of the alternator. Please con-
tact 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 V-belt is defective, increased
steering effort is also required.<
Engine oil pressure
l
Stop the vehicle immediately
and switch off the engine. Check
the engine oil level and refill as required.
If the oil level is correct, please contact
the nearest BMW center.
Do not continue driving. If you do
so, the engine could be damaged
because of inadequate lubrication.<
Tire Pressure Control (RDC)
* l
In addition, an acoustic will go
off: a tire failure has occurred.
Reduce vehicle speed immediately to
stop the vehicle. Avoid hard brake ap-
plications. Do not oversteer.
For additional information, refer to
page 89.
Brake hydraulic system l
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 117 and 136.

Service Interval Display
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
Once the indicator lamp stays on con-
tinuously, there are still approx. 2.1 gal-
lons (8 liters) of fuel left in the fuel tank.
For fuel tank capacity, refer to page 185.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for exam-
ple), there may be slight fluctuations of
the needle.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<462us020
BlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning 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.
Shut off the engine immediately and
allow it to cool down.Between the blue and red zonesNormal operating range. It is not un-
usual for the needle to go as far as the
edge of the red zone in response to
high outside temperatures or severe
operating conditions.Checking coolant level, refer to page 13 5.460de082
Remaining distance for serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OILSERVICE or INSPECTION,
together with the remaining distance
before scheduled service.
The computer bases its calculations of
the remaining distance on the rate of
fuel consumption in the period immedi-
ately preceding your data request.
A flashing display and a "–" in front of
the number indicate that service inter-
val has already been exceeded by the
distance shown in the display. Please
contact your BMW center for an
appointment.46cus006

Tire Pressure Control (RDC)
*
The conceptRDC monitors the tire pressure at all
four wheels – even while you are driv-
ing. The system provides an alert when-
ever the inflation pressure drops signifi-
cantly below the specified pressure in
one or more tires.
In order for the system to "learn" cor-
rect tire inflation pressure, check the
pressure in all the tires, compare your
pressures with those in the tire inflation
tables (page 28), and make corrections
as necessary. Then activate the system.
This indicator lamp in the
instrument cluster informs you
whenever the tire pressure is
not normal.
Activate the system 1 Turn the ignition key to position 2
(do not start the engine)
2 Press the button long enough for
the indicator lamp in the instrument
cluster to light up yellow for a few
seconds
3 After you have driven a few minutes,
RDC imports the current tire inflation
pressures as the nominal values to be
monitored.
You will only have to repeat this proce-
dure following a correction of the tire
inflation pressure. Otherwise, the RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.46cus013
Loss of tire pressureIf the inflation pressure has dropped
significantly over a long period of time
(which is normal for any tire), the
indicator lamp will come on with a
yellow lamp.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not ac-
curate. Please check the inflation pres-
sure again and make corrections ac-
cording to the inflation pressure table.
Then activate the system once again.<

Antilock Brake System (ABS)Antilock Brake System (ABS)/
Cornering Brake Control (CBC) CBC is an advanced engineering de-
sign of the ABS. When braking while
cornering at high speed or braking dur-
ing high lateral acceleration, or when
braking during a lane change, vehicle
stability is improved and steering re-
sponse is enhanced.
In the event of a malfunction
If the ABS warning lamp in the
instrument cluster lights up,
refer to page 22. The brake
system then reverts to conventional
operation as on vehicles without ABS.
However, have the brake system
checked by your BMW center as soon
as possible, to prevent undetected
defects and cumulative faults from
adversely affecting the brake system.
ABS warning lamp for Canadian
models.
If the brake warning lamp
comes on together with the indi-
cator lamps for ABS and DSC –
refer to page 21 – the entire
ABS, CBC and DSC control sys-
tem has failed. Continue driving
cautiously and defensively.
Avoid full brake applications.
This could cause the vehicle to lose
stability and you might no longer be
able to control it.
Have the system checked as soon as
possible by your BMW center.

Coolant Brake fluidAdding coolant Wait until the engine cools before re-
moving the cap from the expansion
tank. The coolant gauge needle in the
instrument cluster must be located in
the blue zone. If it is not, there is a
danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open
the cap
2 If the coolant is low, slowly add
coolant until the correct level is
reached – do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are
required.
Replace the coolant every four years.If the warning lamp for the brake sys-
tem 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 determin-
ing 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 result in extended
pedal travel. Comply with the informa-
tion provided on page 117.
460de128
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 damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion 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 dis-
posal of brake fluid.<

OBD interface socket The interface socket for the onboard
diagnostics is located on the driver's
side at the left-hand bottom of the
dashboard and under a cover. The
cover has the letters "OBD" on it.
The purpose of the OBD system is to
ensure proper emission control system
operation for the life of the vehicle by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.460us250
An illuminated indicator informs
you of the need for service, not
that you need to stop the vehicle.
Your system should be checked by your
BMW center at the earliest possible
opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact your near-
est BMW center immediately. Severe
engine misfire over only a short period
of time can seriously damage emission
control components, especially the
catalytic converter.
Warning lamp: "Service Engine
Soon" for Canadian models
When the fuel filler cap is not pro-
perly tightened, the OBD system
can detect the vapor leak and the indi-
cator will light up. If the fuel filler cap is
then tightened, the indicator will usually
go out after a short period of time.<
