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. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. 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

●

The engine oil pressure is too
low. Stop the vehicle immedi-
ately and switch off the engine. It is not
possible to continue driving. Please
contact the nearest BMW center.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

<

Brake warning lamp

●

If the lamp comes on when the
parking brake is not engaged:
check the brake fluid level. It is very
important that you follow the instruc-
tions on page 128 before driving on.
Have the system checked immediately.

dian models.
Flat Tire Monitor

●

In addition, an acoustic signal is
sounded: there is a flat tire.
Reduce speed and carefully come to a
stop. Avoid sudden braking and steer-
ing maneuvers.
For additional information, refer to
page 83.

Red and yellow: continue driving
cautiously

The brake warning lamp comes
on together with the yellow indi-
cator lamps for ABS

●

and
DSC:
The entire ABS, CBC and DSC
control system has failed. Con-
tinue driving cautiously and
defensively. Avoid hard brake
applications. Please have the system
checked by your BMW center as soon
as possible.

Add washer fluid
The washer fluid level is too low,
top it up at the earliest opportu-
nity.
For additional information, refer to
page 126.
CHECK GAS CAP*

●

This indicator lamp comes on
when the gas cap is loose or
missing.
Close the gas cap tightly: refer to
page 24.
SERVICE ENGINE SOON

●

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 132.
Service Engine Soon indicator
lamp for Canadian models.
Engine electronics

●

There is a fault in the electronic
engine-management system.
You can continue to drive with reduced
engine output or engine speed. Please
have the system inspected at your
BMW center.
Add coolant
The coolant level is too low. Add
coolant at the earliest opportu-
nity.
For additional information, refer to
page 128.

Green: for your information

Turn signal indicator
Flashes when the turn signal is
operated.
Rapid flashing indicates a system mal-
function.
For additional information, refer to

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.<
Coolant consists of water as well as an
additive such as antifreeze with corro-
sion inhibitor. Not all commercially
available additives are suitable for your
BMW. Your BMW center knows which
additives are appropriate.
Only use approved additives, as
the engine could otherwise be
damaged. The additives are hazardous
to your health; therefore, follow the
instructions on the containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze with corrosion inhib-
itor.<
Checking the coolant level and
adding coolantCheck 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 rod is at
least even with the upper edge of the
filler neck; see arrow. The end of the
float may stick out by a maximum of
3/4 in/2 cm – that is, up to the sec-
ond mark on the float
3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until
the correct level is reached – do not
overfill.
Brake fluidIndicator lamp
The warning lamp comes on
even though the parking brake
is released:
The brake fluid level in the reservoir is
too low, refer to page 18. At the same
time, there may be significantly greater
pedal travel. Have the system checked
as soon as possible.
Warning lamp for Canadian
models.
If you continue driving, extended
pedal travel may be necessary
and braking distances may be signifi-
cantly longer. Be sure to adapt your
driving style accordingly.<

129
Adding brake fluidFor 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 may result in extended
brake pedal travel.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the brake system's
safety and reliability, have the brake
fluid changed every two years by a
BMW center. Refer to the Service and
Warranty Information Booklet for US
models or the Warranty and Service
Guide Booklet for Canadian models.
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its closed original container and in
a location which is out of reach of chil-
dren.
Do not spill the brake 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.<

130Maintenance
BMW Maintenance SystemThe BMW Maintenance System helps
maintain your vehicle's road safety and
operational safety. Comfort-related
aspects, such as the timely change of
filters for the air inside the vehicle, are
taken into consideration. The goal is to
optimize maintenance with respect to
low total cost of ownership.
If you should sell your BMW one day,
consistent service and maintenance will
prove to your advantage.
Service interval displayThe service interval display shows you
when an oil service, an inspection –
always alternating between I and II – or
a brake fluid change is due. The special
feature is that the service intervals are
calculated according to your BMW's
individual driving conditions instead of
from fixed mileage increments.
The technology developed for this
takes your personal driving style into
account, as well as your BMW's driving
conditions. After all, short-distance
driving, i.e. frequent cold starts, or driv-
ing off at high engine speeds, affects
your BMW differently from long-dis-
tance driving with the engine at consis-
tent operating temperature.
Special feature regarding engine
oil changeThe calculation of the service intervals
covers practically every kind of operat-
ing situation. If you drive very rarely,
however, you should have the oil
changed at least every two years, since
engine oil deteriorates over time
regardless of use.Service and Warranty Information
Booklet for US models/
Warranty and Service Guide
Booklet for Canadian modelsFor additional information on required
maintenance intervals and procedures,
please refer to the Service and War-
ranty Information Booklet for US mod-
els, or the Warranty and Service Guide
Booklet for Canadian models.
As a precaution against rust, it is advis-
able to have the body checked for dam-
age from rocks or gravel at the same
time, depending upon operating condi-
tions.
