switches on and off the low beams
in response to changes in ambient light
conditions, for instance, in a tunnel, at
dawn and dusk, and in rain and snow.
The LED next to the symbol is illuminated
when the low beams are on.
The low beams remain on indepen-
dent of the ambient lighting condi-
tions when you switch on the fog lamps.
With the daytime driving lamps activated,
the low beams are always switched on in

position 2.<
The automatic headlamp control can-
not serve as a substitute for your per-
sonal judgment in determining when the
lamps should be switched on in response
to ambient lighting conditions. For exam-
ple, the system cannot detect fog. To avoid
safety risks, you should always switch on
the lamps manually under these condi-
tions.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumina-
tion of the road surface. Depending on the
steering angle and other assumptions, the
light from the headlamp follows the course
of the road.
Activating Adaptive Head Light
In ignition key position 2, turn the
light switch to the position 'Auto-
matic headlamp control', refer to
page 85.
So that oncoming traffic is not dazzled,
Adaptive Head Light is
>not active when the vehicle is reversing
>only active toward passenger's side
when stopped.
Malfunction

A congenial climate
90 rently within the vehicle. AUC executes this
function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows
into the vehicle continuously
>Right indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required.
Depending upon air quality require-
ments, in the automatic mode the sys-
tem alternates between its outside-air
and recirculated-air modes
>Left indicator lamp on, recirculated-air
mode: the supply of outside air into the
vehicle is continuously blocked.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing
the air volume as required.
The recirculated-air mode should not be
used over a longer period of time, as the air
quality inside the vehicle deteriorates con-
tinuously.<
Residual heat mode
If you press this button with the
engine switched off, the system
uses the warmth stored in the
engine to heat the interior, for
instance, while the vehicle is
stationary at a school to pick up a child.
You can adjust the automatic climate con-
trol settings as of ignition key position 2.
Provided that the engine has warmed to its
normal operating temperature and the bat-
tery is charged, you can use this function
for up to 15 minutes after switching off the
ignition. The LED within the button lights up
to confirm compliance with both of these
conditions.

transmitter uses an alternating-code sys-
tem. In the case of an alternating-code sys-
tem, program the memory buttons 1 as
described at Alternating-code hand-held
transmitters.<
Alternating-code hand-held

Warning lamp* lights up.
Fuel filler cap is not properly closed
or is missing. Check whether the
fuel filler cap is properly closed.
Fuel specifications
The engine uses lead-free gasoline only.
Required fuel
Premium Unleaded Gasoline,
Minimum Octane Rating: 91.
Minimum Octane Rating corresponds to
the Anti Knock Index AKI and is deter-
mined according to the so-called (R+M)/
2 method.
Do not use leaded gasoline, as other-
wise the lambda probe and catalytic
converter will be permanently damaged.<
Use high-quality brands
Field experience has indicated significant
differences in fuel quality: volatility, compo-
sition, additives, etc., among gasolines
offered for sale in the United States and
Canada. Fuels containing up to and includ-
ing 10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight, that is,
15 % MTBE or 3 % methanol plus an equiv-
alent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may
result in drivability, starting and stall-
ing problems, especially under certain
environmental conditions such as high
ambient temperature and high altitude.
Should you encounter drivability problems
which you suspect could be related to the
fuel you are using, we recommend that you
respond by switching to a recognized high-
quality brand.
Failure to comply with these recommenda-
tions may also result in unscheduled main-
tenance.<

Lamps and bulbs
Lamps and bulbs make an essential contri-
bution to vehicle safety. Therefore, comply
fully with the following instructions during
bulb replacement. If you are not familiar
with the specified procedures, have the
replacements carried out at your BMW
center.Never touch the glass on new bulbs
with your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life.
Use a clean cloth, napkin etc., or hold the
bulb by its metal socket.<
You can obtain a selection of replacement
bulbs at your BMW center.
When working on the lighting system
you should always switch off the
lights affected to prevent short circuits.
To avoid possible injury or equipment dam-
age when changing bulbs, observe any
instructions provided by the bulb manufac-
turer.<
When performing maintenance on the
headlamps, comply with the instructions in
the separate Caring for your vehicle bro-
chure.
In the case of bulbs where the
replacement is not described, please
consult your BMW center.<
Xenon lamps
The service life of these lamps is very long
and the probability of a failure is very low,
provided that they are not switched on and
off an unusual number of times. In the
unlikely event that one of these lamps
should fail, you can continue driving under
poor visibility conditions by switching on
your fog lamps and proceeding carefully,
where allowed by law.
To avoid the risk of potentially fatal
injuries: owing to the extremely high
voltages at which these units operate, ser-
vice work on the xenon lighting system
should only be carried out by a BMW cen-
ter.<
