Indicator and warning
lamps
Technology that monitors itself
Indicator and warning lamps that are iden-
tified by
+ are tested for proper functioning
whenever the ignition key is turned. They
each light up once for different periods of
time.
If a fault should occur in one of these sys-
tems, the corresponding lamp does not go
out after the engine is started or it lights up
again while the vehicle is moving. The indi-
cated pages provide information on what
measures to take.

Installation
Insert the wind deflector in the guides pro-
vided on the rollover bars.
The wind deflector panels inserted in the
rollover bars cannot be removed.
Clothes hooks
Located on the wind deflector panel in the
rollover bars.
Do not hang heavy objects on the
hooks. If you do so, personal injury
could result during braking or evasive
maneuvers, for example.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage
compartment lid is opened
>When attempts are made to start the
vehicle
>To movement inside the vehicle – inte-
rior motion sensor
>To alterations in the vehicle tilt, e.g. as
would occur during attempts to steal
the wheels or tow the vehicle
>To interruption of battery voltage.
The alarm produced by the system in the
event of unauthorized vehicle entry and
attempted theft depends on the country
version:
>Sounding of an acoustical alarm for
30 seconds
>Activation of the hazard warning flash-
ers for approx. five minutes.
Arming and disarming the alarm sys-
tem
When the vehicle is locked or unlocked
either via the driver's door lock or with the
remote control, the alarm system is simul-
taneously armed or disarmed.The hazard warning flashers blink once
when the alarm system has been properly
armed.
You can have different acknowledg-
ment signals set to confirm arming
and disarming.<
You can open the luggage compartment lid
when the system is armed by pressing the
remote control button. Refer to page 19.
When it is closed, the lid is once again
secured.
Manual operation of the luggage
compartment lid triggers the alarm.
Refer to page 21.<
To cancel an alarm:
Press the button on the remote control,
refer to page 18, or turn the ignition key to
position 1. Refer to page 38.
Indicator lamp displays
>The indicator lamp beneath the interior
mirror flashes continuously:
The system is armed
>The indicator lamp flashes when it is
being armed:
A door, the hood or luggage compart-
ment lid is not completely closed. Even
if you do not close the area causing the
alert, the remaining areas are secured
and the indicator lamp flashes continu-
ously after 10 seconds.
However, the interior motion sensor is
not activated

Opening and closing
28 >If the indicator lamp goes out as soon
as the system is disarmed:
No manipulation or attempted intru-
sions have been detected in the period
since the system was armed
>If the indicator lamp flashes for
10 seconds when the system is being
disarmed:
An attempted entry has been detected
in the period since the system was
armed.
After an alarm has been triggered, the indi-
cator lamp will flash continuously.
Interior motion sensor*
The system monitors the footwells and the
seating areas of the driver and passenger.
Deactivate the interior motion sensor
– refer to Avoiding unintentional
alarms – if children or animals are to remain
in the vehicle.<
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor can be deactivated at the same
time. You can do this to prevent a false
alarm from being triggered, for instance in
garages with elevator ramps or when the
vehicle is transported by train.
Lock the vehicle twice = arm the system:
Press the button on the remote control
twice in succession,
or
lock the vehicle twice with the key. Refer to
page 20.

matically depending on road speed.
Rain sensor
The rain sensor is positioned on the wind-
shield, directly behind the interior rearview
mirror.
To activate the rain sensor:
>With the ignition key in position 1 or
higher, move the lever to position 1. The
wipers travel once across the wind-
shield, regardless of the weather.
You can leave the lever permanently in

Do not use the washers if there is any
danger that the fluid will freeze on the
windshield, otherwise vision could be
obscured. For this reason, use an anti-
freeze agent. Refer to page 79.
Do not use the washers when the reservoir
is empty. Otherwise damage to the washer
pump could result.<
Cleaning the windshield
The system sprays washer fluid against the
windshield and activates the wipers for a
brief period.
Cleaning the headlamps

Lamps
Parking lamps/Low beams
Parking lamps
The front, rear and side vehicle
lighting is switched on. You can use
the parking lamps to signal the
position of the vehicle when it is parked.
For information on lighting on one side of
the vehicle for parking, which is available
as an additional feature, refer to page 46.
Low beams
When you switch off the ignition
with the low beam headlamps on,
only the parking lamps will remain
on.
Follow me home lamps:
When you activate the headlamp flasher
after parking the vehicle and switching off
the lights, the low beams will come on for a
brief period.
You can also have this function acti-
vated/deactivated if you wish.<
Defective bulbs
The defective bulb indicator lamp
lights up:
At least one bulb of the vehicle's
exterior lighting has failed.
For replacing bulbs: refer to page 84.
LIGHTS ON warning
Whenever you open the driver's door after
having turned the ignition key to position 0,
you will hear an acoustic signal for a few seconds to remind you that the lamps have
not been switched off
.
Daytime driving lamps*
If you wish, the light switch can be left in
the second position. When the ignition is
switched off, the external lighting is also
switched off.
You can have the activation settings
for the daytime driving lamps pro-
grammed on your vehicle.<
Automatic headlamp control*
When the switch is set to this posi-
tion, the system automatically
switches the low beams on and off
in response to changes in ambient light – in
tunnels, at dusk, etc. – as well as to rain and
snow.
The vehicle's external lights remain
on constantly when you switch on the
front fog lamps after the headlights have
come on automatically.<
Automatic headlamp control cannot
serve as a substitute for the driver's
judgement in determining when the vehicle
lights should be switched on. For example,
the sensors are not able to detect fog. To
avoid safety risks, you should respond to
these kinds of low-visibility situations by
switching the headlights on manually.<
You can have the sensitivity of your
vehicle's automatic headlamp control
adjusted.<

>Forceful braking and braking with ABS:
Brake lamps 1 and 2 light up on both
vehicle sides together with the center
brake lamp.
Antilock Brake System ABS
The concept
ABS keeps the wheels from locking during
braking, thereby enhancing active driving
safety.
Malfunction
If the yellow indicator lamps for the
Antilock Brake System ABS come
on together with the brake warning
lamp and the indicator lamp for the
Dynamic Stability Control DSC:
The entire ABS and DSC control
system has failed. Continue driving
cautiously and defensively. Avoid
hard brake applications. Please have the
system checked by your BMW center as
soon as possible.
ABS and DSC indicator and warn-
ing lamps for Canadian models.
Braking with ABS
If you are in a situation which requires full
braking, you will exploit the full benefits of
the ABS system if you apply maximum
brake pressure – panic stop.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Flat Tire Monitor
The concept
The tire pressure is determined using the
signals of the ABS sensors.
The system provides an alert whenever the
tire pressure of one tire drops relative to
that of another.
Prerequisites
In order for the system to "learn" the cor-
rect tire inflation pressures, please do the
following:
>Check the inflation pressure in all tires
>Compare to the inflation pressure table
– refer to page 72 – and correct if nec-
essary
>Initialize the system.
Check the tire pressures regularly
and correct if necessary. Refer to
page 71.<
Indicator lamp
In the event of a flat tire
The indicator lamp lights up red; in
addition, an acoustic signal is
sounded:
Respond immediately by carefully reducing
vehicle speed to under 50 mph / 80 km/h.
Avoid hard brake applications and steering
maneuvers.
If your vehicle is equipped with
Run Flat tires, note the information on
page 75.<
The Flat Tire Monitor cannot alert you
to severe and sudden tire damage
caused by external factors. Another factor
which the Flat Tire Monitor does not recog-
nize is the even and very gradual pressure
loss that takes place in all tires over an
extended period of time.<

Refueling

Refueling
Fuel filler door
1.Open fuel filler door
2.Turn the filler cap in a counter-clock-
wise direction
3.Place the filler cap in the bracket on the
filler door.
Releasing manually
If an electrical malfunction occurs, you can
unlock the fuel filler door manually.
1.Remove the covers of the tail lamps by
turning the lock to the right; refer also to
page 87
2.Pull the luggage compartment trim
panel slightly toward the interior.
The green button with the fuel pump
symbol is revealed
3.Undo the adhesive strip and pull off
4.Pull on the knob
Fuel filler cap is released.
Fuel gas cap
Close the gas cap carefully after refu-
eling until a "click" is heard. While closing, be sure not to squeeze the strap
which is fastened to the cap. A loose or
missing cap will activate the "Check gas
cap" lamp.<
Check gas cap
This indicator lamp comes on when
the fuel gas cap is loose or missing.
Close the gas cap tightly as described
above.
Tank capacity: approx. 14.5 gallons /
55 liters, of which approx. 2.1 gallons /
8 liters are reserve capacity.
Simple and environmentally friendly
When handling fuels, comply with all
of the applicable safety precautions
posted at the service station.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Pulling the nozzle
out of the pipe during refueling
>results in premature shutoff
>and will reduce the effect of the vapor
recovery system on the pump.
The fuel tank is full when the filler nozzle
shuts off the first time.
Fill the fuel tank before it is com-
pletely empty. Driving to the last drop
of fuel can prevent the engine from operat-
ing properly and result in damage.<
Fuel specifications
The engine uses lead-free gasoline only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index.
Do not use leaded fuels. The use of
leaded fuels will cause permanent
damage to the system's oxygen sensor and
the catalytic converter.<
