Indicator and warning lamps
Tire Pressure Warning (RDW) l
RDW 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
pages 26, 78.
Dynamic Stability Control
(DSC) l
The indicator lamp flashes when
the system is active and governs drive
force and braking force.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving and stays on:
DSC has been switched off via the
button or because of a malfunction.
In the event of a malfunction, have the
system checked by the nearest BMW
center.
For additional information, refer to
page 76 and on.
Add washer fluid
The washer fluid is too low.
Top up the fluid at the earliest
opportunity.
For additional information, refer to
page 122.
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 135.
Warning lamp: Service Engine
Soon for Canadian models.
Engine electronics l
There is a fault in the engine's
electronic control system. The
electronics allow for continued driving
with reduced engine output or speed.
Please have the system inspected by
your BMW center.
Add coolant
The coolant level is too low.
Add coolant at the earliest
opportunity.
For additional information, refer to
page 125.
Green: for your information
Turn signal indicator
Flashes when the turn signal is
on. Rapid flashing: indicates a
system malfunction.
For additional information, refer to
page 65.
Cruise control
Lights up when the cruise
control is activated. Available for
operation via the multifunction steering
wheel (MFL).
For additional information, refer to
page 67.
Fog lamps
Lights up whenever fog lamps
are on.
For additional information, refer to
page 82.
Blue: for your information
High beams
Lights up when the high beams
are on or the headlamp flasher
is actuated.
For additional information, refer to
pages 65, 82.

Fuel gauge Coolant temperature gauge Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
For fuel tank capacity, refer to
page 169.
If the tilt of the vehicle varies (when you
are driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
When the ignition is turned on, the indi-
cator lamp in the fuel display will light
up briefly as a functional check.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds. RedTo check the function, the warning
lamp in the coolant temperature gauge
will light up briefly when the ignition is
turned on.
If the lamp comes on while operating
the vehicle, the engine has overheated.
Switch the engine off immediately and
allow it to cool down.
Checking coolant level, refer to
page 125.
Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response to
high outside temperatures or severe
operating conditions.

Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you do, escaping coolant can cause
burns.
To avoid the possibility of damage later
on, never use anything other than
factory-approved, nitrite and amino-
free extended-duty antifreeze with
corrosion inhibitor. Your BMW center is
familiar with the official specifications.
Antifreeze and anticorrosion agents are
hazardous to health. You should always
store them in original containers and in
a location inaccessible to children.
Extended-duty antifreeze with corro-
sion inhibitor contains ethylene glycol,
a flammable substance. For this reason,
do not spill long-life antifreeze with
corrosion inhibitor on hot engine parts.
It could catch fire and cause burns.<
Check the coolant level and add
coolant Check the coolant level when the
engine is cold (approx. 68 7 or
+20 6). The coolant gauge needle in
the instrument cluster must be located
in the blue field, as otherwise you could
be scalded when adding more fluid.
1 Open the cap for the expansion tank
by turning it slightly counter-clock-
wise to allow accumulated pressure
to escape. Then open
2 The coolant level is correct whenever
the upper end of the red float rod is
aligned with the upper edge of the
filler neck (refer to the arrow in the
illustration and the schematic
diagram next to the filler neck as well)
3 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.Change the coolantReplace the coolant every three years.
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
