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. There is a malfunction
of the alternator drive belt or in the
charging circuit of the alternator. 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

●

An alarm sounds at the same
time. Stop vehicle immediately
and switch off engine. 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, as the
engine could sustain serious dam-
age from inadequate lubrication.

<

Flat Tire Monitor

●

In addition, an acoustic signal is
sounded: a tire failure has
occurred. To come to an immediate
stop, reduce speed, while avoiding any
sudden, jerky braking or steering
maneuvers.
For additional information: refer to
page 82
Brake warning lamp

●

If the lamp comes on when the
parking brake is not engaged:
check the brake fluid level. Before driv-
ing further, be sure to comply with the
instructions on pages 108 and 121.
Brake warning lamp for Cana-
dian models.

Red: an important reminder

Brake warning lamp

●

Comes on when the parking
brake is engaged – an additional
acoustic signal sounds when starting
off. For additional information: refer to
page 63
Brake warning lamp for Cana-
dian models.
Please fasten safety belts

●

Comes on together with an
acoustic signal until the safety
belts are fastened.
For additional information on safety
belts: refer to page 47
Airbags

●

Please have the system
inspected at your BMW center.

page 53

Dynamic Stability Control
(DSC)

●

The indicator lamp flashes and
an acoustic signal sounds: the system
is active and governs drive and braking
force.
If the indicator lamp fails to go out after
the engine has been started, or if it
comes on during normal driving and
stays on:
DSC has been deactivated, either at the
button or in response to a system mal-
function.
In the event of a malfunction, have the
system checked by your nearest BMW
center.
For additional information: refer to
page 81
Dynamic Brake Control (DBC)

●

Malfunction in DBC system.
Conventional braking efficiency
is available and unrestricted.
Have the system checked and repaired
at your BMW center as soon as possi-
ble.
For additional information: refer to
page 82
Dynamic Brake Control (DBC)
warning lamp for Canadian
models.

Add washer fluid
The washer fluid is too low. Top
off the fluid at the earliest
opportunity.
For additional information: refer to
page 118
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 124
SERVICE ENGINE SOON warn-
ing 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
Coolant level too low, top up as
soon as possible.
For additional information: refer to
page 120
CHECK FILLER CAP

●

This indicator lamp comes on
when the fuel filler cap is loose
or missing.
Close the filler cap tightly: refer to
page 24

Green: for your information

Turn signal indicator
Flashes when turn signals are
on. Rapid flashing: indicates a
system malfunction.
For additional information: refer to
page 70
Cruise control
Lights up when the cruise con-
trol is activated. Ready for oper-
ation via the steering wheel with multi-
function buttons.
For additional information: refer to
page 72
Front fog lamps
Lights up whenever the fog
lamps are on.

Brake systemBrake fluid levelLow brake fluid level in the reservoir
combined with longer than usual pedal
travel may indicate a defect in one of
the brake system's hydraulic circuits.
Proceed to the nearest BMW cen-
ter. Higher brake application pres-
sure may be necessary when stopping,
and the vehicle may exhibit a slight ten-
dency to pull to one side. Brake dis-
tances may even be longer. Please
remember to adapt your driving style
accordingly. sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
rotors by brake applications is not
reached.
Corrosion on brake rotors is signaled by
a running or pulsation during braking;
even extended subsequent braking will
not cure this phenomenon.
It is a good idea to periodically dry the
brakes with a gentle application when
driving in rain and on wet roads. Watch
traffic conditions to ensure that this
maneuver does not endanger other
road users. The heat generated in this
process helps dry the pads and rotors
to ensure that your brake system will
respond with undiminished efficiency
when you need it.
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake applica-
tions are required. This helps avoid
placing excessive loads on the brake
system. Stay within the allowable rpm
range. For additional information, refer
to page 74.
Do not coast with the clutch
depressed or with the gearshift
lever in idle. Do not coast with the
engine switched off. If you do so the
engine provides no braking effect and
there is no power assist for braking or
steering when the engine is not run-
ning.<
Brake pads
For your own safety: use only
brake pads which BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suitable for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until
the correct level is reached — do not
overfill.
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze agents with corro-
sion inhibitor.<
Brake fluid
The brake warning lamp comes
on when the parking brake is
not engaged: brake fluid level
too low, refer to page18.
Brake warning lamp for Cana-
dian models.
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.
Due to loss in brake fluid, pedal travel
can lengthen and braking efficiency
may be reduced. Refer to the informa-
tion 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 by
a BMW center. Refer also to the Service
and Warranty Information Booklet for
US models or in 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 original container and in a loca-
tion inaccessible to children.
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.<
