Indicator and warning lamps 
 
Technology that monitors itself 
 
Many of the systems of your BMW 
monitor themselves automatically, both 
during engine starts and while you are 
driving. Indicator and warning lamps 
that are identified by "
 
l
 
" are tested for 
proper functioning whenever the igni-
tion key is turned. They each light up 
once for different 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 
 
l
 
 
The battery is no longer being 
charged. There is a malfunction 
of the alternator ribbed V-belt or in the 
charging circuit of the alternator. Please 
contact the nearest BMW center.
If the ribbed V-belt is defective, do 
not continue driving. If you do so, 
the engine could be damaged due to 
overheating. If the ribbed V-belt is de-
fective, increased steering effort is also 
required.<
Engine oil pressure l 
Stop the vehicle and switch off 
the engine immediately. Check 
the engine oil and top up as required. If 
the oil level is correct, please contact 
the nearest BMW center.
Do not continue driving. If you do 
so, the engine could be damaged 
because of inadequate lubrication.< 
Tire Pressure Control (RDC)
* l
In addition, an acoustic signal is 
sounded: A tire failure has oc-
curred. Reduce vehicle speed immedi-
ately and stop the vehicle. Avoid hard 
brake applications. Do not oversteer. 
For additional information: Refer to 
page 80.
Brake hydraulic system l
If the lamp comes on when the 
parking brake is not engaged: 
Check the brake fluid level. Before driv-
ing further, be sure to read the notes on 
pages 109 and 129.

Indicator and warning lampsYellow: Stop immediately
Engine oil level
 
Comes on while driving: Stop 
the vehicle and switch off the 
engine immediately. The oil level is at 
the absolute minimum.
For additional information: Refer to 
page 125.
Do not continue driving until you 
have topped up the engine oil. If 
you continue to drive, the engine could 
be damaged because of inadequate 
lubrication.< 
Red and yellow: Continue driving 
cautiously 
Cornering Brake Control (CBC) l
If 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. 
For additional information: Refer to 
pages 79 and 107.

Red: An important reminder
Parking brake
Comes on when the parking 
brake is applied Ð an additional 
acoustic signal sounds when starting 
off. 
For additional information: Refer to

dian models.
Please fasten safety belts l 
An acoustic warning signal 
sounds simultaneously. Lights 
up for a few seconds or until the safety 
belt is fastened. 
For additional information on safety 
belts: Refer to page 54.
Airbags l 
Please have the system in-
spected by your BMW center.

Malfunction in engine timing. 
Higher brake application pressure may 
be necessary and brake pedal travel 
may be significantly longer. Please have 
the system inspected by your BMW 
center.
Add coolant
The coolant level is too low. Top 
up the coolant at the earliest 
opportunity. 
For additional information: Refer to

Turn signal indicator
Flashes when the turn signal in-
dicator is actuated. Includes the 
trailer turn signals if you are towing a 
trailer. Rapid flashing indicates a sys-
tem malfunction.

Comes on when the cruise con-
trol is activated. Available for 
operation via the multifunction steering 
wheel. 
For additional information: Refer to

Antilock Brake System (ABS)Antilock Brake System (ABS)/
Cornering Brake Control (CBC) CBC is an advanced engineering devel-
opment of ABS. When braking during 
cornering with high lateral accelera-
tion, or when braking during a lane 
change, vehicle stability is improved 
and the steering response is enhanced.
In the event of a fault 
If the ABS in the instrument 
cluster lights up, refer to 
page 22. The brake system then 
reverts to conventional operation as on 
vehicles without ABS. However, have 
the brake system checked by your 
BMW center as soon as possible. To 
prevent undetected defects and cumu-
lative faults from adversely affecting the 
brake system, refer any problems to 
your BMW center at the earliest oppor-
tunity.
ABS warning lamp for Canadian 
models.
If the brake warning lamp 
comes on together with the indi-
cator lamps for ABS and DSC 
(refer to page 21), the entire 
ABS, CBC and DSC control sys-
tem has failed. Continue driving 
cautiously and defensively. 
Avoid full brake applications. 
This could cause the vehicle to lose 
stability and you might no longer be 
able to control it.
Have the system checked as soon as 
possible by your BMW center.

Brake systemBrake fluid level 
If the brake warning lamp 
comes on and the parking brake 
has been released:
The brake fluid level is too low in the 
reservoir (refer to page 129).
If the brake fluid level is too low and 
brake pedal travel has become notice-
ably longer, there may be a defect in 
one of the hydraulic circuits of the brake 
system.

dian models.
Proceed to the nearest BMW 
center. Higher brake application 
pressure may be necessary under these 
conditions, and brake pedal travel may 
be significantly longer. Please remem-
ber to adapt your driving style accord-
ingly.<
Brake pads
If the warning lamp for the brake 
pads lights up:
The brake pads have reached 
their minimum pad thickness. Proceed 
to the nearest BMW center as soon as 
possible to have the pads replaced.
For your own safety: Use only 
brake pads that BMW has ap-
proved for your particular vehicle 
model. BMW cannot evaluate non-
approved brake pads to determine if 
they are suited for use, and therefore 
cannot ensure the operating safety of 
the vehicle if they are installed.<
