RefuelingFuel filler door
Always switch off the engine
before refueling, as it is not possi-
ble to add fuel with the engine running,
and attempts may also trigger the
SERVICE ENGINE SOON lamp.<
Press on the rear edge of the fuel filler
door to open and close it.
Pull the knob with the fuel pump sym-
bol, located on the right side wall of the
luggage compartment.
Always observe all safety precau-
tions posted at the service station
when handling fuel.
Never carry spare fuel containers in
your vehicle. Whether empty or full,
these containers can leak, cause an
explosion, or lead to fire in the event of
a collision.<
Simple and environmentally
friendly
Open the gas cap carefully to pre-
vent fuel from spraying out. Fuel
spray may cause injury.<
Keep the gas cap in the bracket
attached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Lifting the
nozzle during refueling
>results in premature pump shutoff
>and will reduce the effectiveness of
the vapor recovery system on the
pump.
The fuel tank is full when the filler noz-
zle shuts off the first time.

61 Passenger safety systems
Airbags1Front airbags on the driver and pas-
senger sides
2Side airbags on the driver and pas-
senger sides – front and rear*Protective effectThe front airbags supplement the three-
point safety belts by providing addi-
tional protection in the event of a
severe frontal collision in which the pro-
tection afforded by the belts alone may
no longer be sufficient. The side airbags
provide protection in the event of a col-
lision from the side. They help support
the respective seat occupant's upper
body.
For information on the correct sitting
posture, refer to page 52.
The side airbags in the rear pas-
senger area* of your vehicle may
already have been deactivated by a
BMW center. You may have them acti-
vated if you desire to do so. Please
contact your BMW center for additional
information.<
The airbags do not deploy in
response to minor collisions, rear
impacts and certain kinds of vehicle
rollover.<
Do not apply adhesive materials to
the cover panels of the airbags,
cover them or modify them in any other
way. Do not remove the airbag restraint
system. In the event of a malfunction,
deactivation or triggered activation – as
a response to an accident – of the air-
bag restraint system, consult your BMW
center for inspection, repair or disas-
sembly. Do not modify or tamper with
either the wiring or the individual com-
ponents in the airbag system. These
include the upholstered covers on the
steering wheel, instrument panel, side
trim panels of the doors and front roof
pillars and on the sides of the headliner.
Also, do not attempt to remove the
steering wheel. Unprofessional
attempts to service the system could
lead to failure in an emergency or
undesired airbag activation, either of
which could result in personal injury. Do
not touch the individual components
immediately after the system has been
activated, as this could result in per-
sonal injury.<

3. Keep pressing down on the protec-
tive bar – see arrow 1 – from on top
until you hear it click into place
4. Put the cover panel back in place
and press down firmly
5. Push the back panel of the head
restraint closed – see arrow 2.
Do the same for the second protective
bar. If you are not familiar with any of
the procedures, consult your BMW
center.
Have the rollover protection system
checked out by your BMW center after
it has been inadvertently triggered.
Do not move the convertible top
under any circumstances if the
rollover protection system has
extended.
Do not use the rear head restraints as
storage shelves.
Absolutely no modifications are to be
made to any of the rollover protection
system's individual components or any
of its wiring.
Only your BMW center is to carry out
any work on the rollover protection sys-
tem.
Work done on the system that is carried
out improperly could lead to failure in
an emergency or accidental activation.
Regarding having the system checked
to ensure long-term operation: be scru-
pulous in adhering to the Service inter-
val display for maintenance intervals.
Every 2 years at the latest, the rollover
protection system must be inspected at
a BMW center.<

If the engine does not start on the first
attempt – if it is very hot or cold, for
instance:
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera-
tures below approx. +57/–156 and at
altitudes over 3,300 ft/1,000 m:
>On the first start attempt, it may be
necessary to engage the starter for a
longer period – but no longer than
20 seconds
>Press the accelerator pedal halfway
down while engaging the starter.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged can damage the catalytic con-
verter.<
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharg-
ing, always deactivate electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.Manual transmission1. Engage the parking brake
2. Gearshift lever in idling position
3. Start the engine.Automatic transmission1. Depress footbrake
2. Place the selector lever in position P
or N
3. Start the engine.
To prevent the vehicle from start-
ing off on its own, always move
the selector lever to position P and
engage the parking brake before leav-
ing your vehicle with the engine run-
ning.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a safety hazard. 2. Move selector lever into position N
3. Start the engine.
If the engine does not start, reen-
gage the gear last selected, refer
to the gear indicator in the display, and
move the selector lever into neutral
position N again.
The gearbox is automatically taken out
of gear if the driver's door is opened
while the engine is running and the
driver does not actuate the pedals, the
shift paddles or the selector lever. This
is accompanied by a warning tone and
the flashing gear indicator. The gear
display N appears in the instrument
cluster.<
Before exiting the vehicle with the
engine running, move the selector
lever into position N and apply the park-
ing brake.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a safety hazard.<

Service interval displayRemaining distance to next
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or higher or
after the engine is started.
The next service due appears with the
message OIL SERVICE or
INSPECTION, together with the dis-
tance remaining in miles – in kilometers
in Canada – before the next scheduled
service.
The computer bases its calculations of
the remaining distance on the preced-
ing driving style.
A flashing message and a "–" in front of
the number mean that the service inter-
val has already been exceeded by the
distance shown on the display. Please
contact your BMW center for an
appointment.
Check ControlDisplayWhen the ignition key is in position 2,
the following information and/or condi-
tions are indicated using symbols until
the conditions have been corrected.
1Check the low and high beams as
well as the parking lamps
2Door open
3Luggage compartment lid open
4Check tail or brake lamps
When you open the driver's door after
having turned the ignition key to posi-
tion 0, you will hear an acoustic signal
for a few seconds to remind you that
the lamps have not been switched off.

Under these special circumstances
traction is increased by deactivating the
control systems that enhance traction
under normal conditions.Deactivating the DSC and the
DTCHold the DSC button down for at least
3 seconds. The indicator lamp and the
yellow brake warning lamp light up and
remain on continuously.
The systems for enhancing stability and
traction are deactivated, and there is no
active braking intervention or torque
control.
To maintain vehicle stability,
always drive with the DSC acti-
vated whenever possible. lamp or the indicator lamps will go out.
DTC is deactivated.
The laws of physics cannot be
repealed even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the sys-
tem as an excuse for taking risks.
Whenever the DTC is activated, the
DSC is switched off and performs minor
stabilizing intervention.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Flat Tire Monitor*The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.Functional requirementsIn order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation
pressure table on page 25 and cor-
rect them, if necessary
3. Initialize the system.
