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.

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 116 and 129.

In addition, an acoustic signal is 
sounded: a tire failure has occurred. 
Reduce vehicle speed immediately and 
stop the vehicle. Avoid hard brake 
applications. As you steer the vehicle, 
use caution and avoid overcorrecting.

pages 85, 86
 
Red and yellow: continue driving 
cautiously
 
The brake warning lamp comes 
on together with the yellow indi-
cator lamps for ABS

The entire ABS, CBC, 
ASC+T/DSC and 
ADB/ADB-X/DBC control sys-
tem has failed. Continue driving 
cautiously and defensively. Avoid full 
brake applications. Please have the 
system checked by your BMW center 
as soon as possible.

This indicator lamp comes on 
when the fuel filler cap is loose 
or missing.
Close the filler 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.

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.Interior motion sensorIn order for the interior motion sensor to 
function properly, the windows and 
sliding/tilt sunroof must be completely 
closed.
Nevertheless, you should deactivate 
the interior motion sensor, see Avoiding 
unintentional alarms, if
>persons or animals are left in the 
vehicle
>the windows or the sliding/tilt 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 sliding/tilt sun-
roof is interrupted in the first 10 sec-
onds and then restarted. The alarm 
must then be disarmed and reactivated 
before it will resume operation.<

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 sys-
tem immediately.
Transporting children safelyCommercially available child-restraint 
systems are designed to be secured 
with a lap belt or with the lap belt por-
tion of a combination lap/shoulder belt. 
Improperly or inadequately installed 
restraint systems can increase the risk 
of injury to children. Always read and 
follow the instructions that come with 
the system.
Child-restraint system with 
tether strapIf you use a child-restraint system with 
a tether strap, three additional tether 
anchorage points have been provided – 
refer to the arrows in the illustration.
To gain access to this anchor fitting lift 
the plastic plug, see arrows, with the 
help of a screwdriver.

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.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 128.
Between the blue and red zonesNormal operating temperature. The 
needle may rise as far as the edge of 
the red sector in normal operation.

Initializing the systemInitializing is necessary to familiarize the 
system with the correct inflation pres-
sure.
Repeat this process after any changes 
in tire inflation pressure, tire rotation or 
replacement. Do not carry out further 
system initialization after adjusting the 
inflation pressure and letting the system 
"learn" the correct pressures.
1. Check the tire inflation pressures in 
all the tires, comparing them with the 
inflation pressure chart on page 25 
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press button as long as you need to 
until the indicator lamp in the instru-
ment cluster lights up. After a little 
while, the indicator lamp will go out 
by itself
4. After a few minutes' driving time, the 
Flat Tire Monitor adopts the current 
pressure levels as the reference, and 
from that point on, can detect and 
report a flat tire.
To activate/deactivate the systemThe Flat Tire Monitor automatically 
assumes operation whenever you turn 
the ignition key to position 2.
To deactivate the system: press the 
button. The yellow indicator lamp 
comes on.
To activate the system: press the but-
ton again. The indicator lamp goes out.
You should deactivate the system 
before driving with snow chains, as the 
chains can generate spurious warnings 
and/or prevent the system from detect-
ing actual pressure loss.

Flat tire
The red warning lamp in the 
instrument cluster lights up to 
warn of pressure loss and tire 
failure. This visual alert is accompanied 
by an acoustic warning signal. Reduce 
your speed immediately, and steer and 
brake gently as you bring the vehicle to 
a stop.
To reset the warning lamp: after replac-
ing the flat tire you will need to reset the 
red warning lamp manually. Maintain 
pressure on the Flat Tire Monitor button 
until the warning lamp goes out. Then 
reinitialize the system.
The Flat Tire Monitor cannot pro-
vide you with advance warning of 
sudden and severe tire damage caused 
by external factors.
The system also does not detect the 
gradual and minor loss of pressure that 
all tires display over extended periods 
of time.<
Check tire inflation pressures on a 
regular basis, correcting them as 
necessary, refer to page 25.
The system may respond to operation 
on slippery or snow-covered road sur-
faces with false warnings or delays in 
detecting actual pressure loss.
Performance-oriented driving – slip at 
the drive wheels, high rates of lateral 
acceleration – can also increase the 
time that the Flat Tire Monitor requires 
to detect a flat tire.<
System malfunctionsThe yellow indicator lamp in the instru-
ment cluster lights up and remains on 
until the problem is corrected.
Please refer the problem to your BMW 
center.
