Dynamic Brake Control (DBC)

●

Malfunction in the DBC system.
Conventional braking efficiency
is available and unrestricted.
Have the system checked as soon as
possible.
For additional information, refer to
page 115.
Dynamic Brake Control (DBC)
warning lamp for Canadian
models.
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

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.

Indicator and warning lamps

75
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 range. The needle
may rise as far as the edge of the red
sector during normal operation.RedWhen you switch on the ignition, the
warning lamp comes on briefly as an
operation check.
If the lamp comes on during normal
vehicle operation: the engine has over-
heated. Stop and switch the engine off
immediately and allow it to cool down.
To check coolant level, refer to
page 128.

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.<
