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 in the
following section.
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
●
Stop the vehicle immediately
and switch off the engine.
Check the engine oil level and top off as
required. If the oil level is correct:
please contact the nearest BMW cen-
ter.
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. Before driv-
ing further, be sure to comply with the
instructions on pages 122 and 135.

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 91
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, DSC and
ADB-X/DBC control system has
failed. Continue driving cau-
tiously and defensively. Avoid
full 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 off the fluid at the earliest
opportunity.

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.

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.

armed: an attempted entry has been
detected in the period since the sys-
tem was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.Avoiding unintentional alarmsThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered in garages
with elevator ramps, for instance, or
when the vehicle is transported by train:
Lock the vehicle twice to arm the sys-
tem. Press the button on the remote
control twice in succession or lock the
vehicle twice with the key.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated as long as the system is
armed.
You can have the tilt alarm sensor
and the interior motion sensor
permanently deactivated.<
Interior motion sensorIn order for the interior motion sensor to
function properly, the windows and the
glass sunroof must be completely
closed.
Nevertheless, you should deactivate
the interior motion sensor, refer to
Avoiding unintentional alarms, if
>persons or animals are left in the
vehicle
>the windows or the glass sunroof are
being left open.
The system deactivates the tilt-
alarm sensor and the interior
motion sensor if the convenience clos-
ing of windows and the glass sunroof is
interrupted in the first 10 seconds and
then restarted. The alarm must then be
disarmed and reactivated before it will
resume operation.<

This is the right way a larger child
should sit wearing the seat belt when
rear side airbags are provided.Indicator lamp
The indicator lamp indicates the
operational status of the airbag
system with the ignition key in
position 1 or higher.
System operational:
>The indicator lamp comes on briefly
when you turn the ignition key to
position 1 or higher.
System malfunction:
>The indicator lamp does not come on
or
>the indicator lamp lights up continu-
ously.
If there is a system malfunction, there is
a risk that the airbags will not be trig-
gered within their normal response
range, even if the level of impact would
normally have triggered them.
Have your BMW center inspect the air-
bag system immediately.

Sport programYou can choose between two driving
programs: smoothly dynamic or Sport.
With the Sport program, gearshifts are
faster in sequential mode and the shift
points are adapted in drive mode.
To activate the Sport program: press
the SPORT button. The LED in the but-
ton lights up.Acceleration assistantThe acceleration assistant permits opti-
mum racing-style acceleration on roads
with good grip.
Do not use the acceleration assis-
tant frequently as this could other-
wise cause premature wear of the com-
ponents.<
1. Activate the Sport program
2. Press and hold the DSC button, refer
to page 86, for more than three sec-
onds
3. Quickly press the accelerator pedal
down fully: kickdown. The optimum
rpm for driving off will be adjusted.
To maintain vehicle stability,
always drive with the DSC acti-
vated whenever possible.<

Fuel gaugeOnce the indicator lamp stays on con-
tinuously, there are still approx.
2 gallons/8 liters of fuel in the fuel tank.
Fuel tank capacity approx.
16.6 gallons/63 liters
Certain operating conditions, such as
those encountered in mountainous
areas, may cause the needle to fluctu-
ate slightly.
Fill the fuel tank before it is com-
pletely empty. Driving to the last
drop of fuel can prevent the engine
from operating properly and result in
damage.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
Engine coolant temperature gaugeBlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.Between the blue and red zonesNormal operating temperature. The
needle may rise as far as the edge of
the red sector in normal operation.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 during normal
vehicle operation: the engine has over-
heated. Switch off the engine immedi-
ately and allow it to cool down.
To check coolant level, refer to
page 134.

Flat Tire Monitor*The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.Functional requirementsIn order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation
pressure table on page 26 and cor-
rect them, if necessary
3. Initialize the system.
System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
>Driving on snow-covered or slippery
roads
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>When driving with snow chains, false
warnings and undetected pressure
losses may occur
>When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Initializing the system
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to until the yellow indicator lamp in
the instrument cluster lights up for a
few seconds
3. Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.
