Refueling Fuel filler door
Before filling the tank, shut off the
engine. If you do not, fuel cannot
be filled into the tank and the "Service
Engine Soon" lamp may come on.<
Press on the rear edge of the fuel filler
door to open and close it.
To unlock the filler door if the central
locking system fails, refer to page 161.
When handling fuels, comply with
all of the applicable safety precau-
tions and regulations pertaining to
fuels.
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 friendly to the
environment
Open the filler cap carefully to
prevent fuel from spraying out.
Fuel spray may cause injury.<
Keep the filler cap in the bracket
attached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refu-
eling
>results in premature pump shutoff
>and will reduce the effect of the vapor
recovery system on the pump.
The fuel tank is full, whenever the fuel
nozzle shuts off the first time, as is
specified for proper service.
Tank capacity, refer to page 181.
Close the fuel cap carefully after
refueling 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
"Service Engine Soon" warning lamp.<

Fuel specifications Tire inflation pressuresThe 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 perma-
nent damage to the system's oxygen
sensor and the catalytic converter.<
The correct tire inflation pressures are
on a sticker attached to the B-pillar and
visible with the driver's door open.Checking tire pressuresAll tire pressure and ambient air
temperature specifications are stated in
the units usually used in your country
(psi; kilopascal) (also see the following
tire inflation pressure table).
After correcting the tire inflation pres-
sure, re-initialize the Tire Pressure
Warning system (RDW) so that it can
monitor the tire inflation pressure. Refer
to page 81.
Check tire inflation pressures
regularly – at least every two
weeks and before beginning a longer
trip. Otherwise, incorrect tire pressure
can lead to poor handling, tire damage
and accidents.< Comply with tire approval
specifications The inflation pressures in the table
apply to tires made by BMW approved
manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
made by other manufacturers. You will
find a list of approved tire sizes on
page 120.
Your vehicle is equipped with tires that
not only meet US standards, but also
European standards. We recommend
the exclusive use of BMW approved
tires.

Luggage compartment Alarm system
*
When opening the convertible top,
refer to page 45, make sure that
the luggage compartment is set up
properly, as otherwise damage may
occur.<
The conceptThe vehicle alarm system responds:
>When a door, the hood or the
luggage compartment lid is opened
>To movement inside the vehicle (inte-
rior motion sensor)
>Altering the vehicle tilt angle, e. g. as
would occur while attempting to steal
the wheels or tow the vehicle (tilt
alarm sensor)
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustical alarm for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
the same rhythm.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
by using a key or with the remote
control, the alarm system is also simul-
taneously armed or disarmed.
The interior motion sensor is activated
approx. 30 seconds after you have
locked the vehicle.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have a signal set as
acknowledgment for both setting
and deactivating the alarm.<
You can also open the luggage
compartment lid when the system is
armed by pressing button 3 of the
remote control (refer to page 37). When
it is closed, the lid is once again
secured.

1 Odometer
2 Trip odometerOdometerYou can activate the displays shown in
the illustration with the ignition key in
position 0 by pressing the button
(arrow) in the instrument cluster.Trip odometerTo reset the trip odometer to zero,
press the button (arrow) with the igni-
tion key in position 1 and up.
Variable pre-warning zoneThe orange pre-warning zone displays
current permissible engine speeds,
depending on the engine temperature.
As the engine temperature climbs, the
sectors for this pre-warning zone will
go out one after the other.
Avoid engine speeds in the pre-warning
zone if possible.Warning zone
Always avoid engine speeds in the
red warning zone, as otherwise
the engine may be damaged.<
To protect the engine, the fuel supply is
automatically interrupted in this zone;
you will notice a loss of power.
The general operating temperature is
between 175 7 (80 6) and 250 7
(120 6). During performance-oriented
driving, do not exceed the maximum
temperature of 300 7 (150 6).

Fuel gauge Coolant temperature gauge Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
For fuel tank capacity, refer to
page 181.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for
example), there may be slight fluctua-
tions of the needle.
Fill the fuel tank well before it is
empty. Driving to the last drop of
fuel can result in damage to the engine
and/or the catalytic converter.<
When the ignition is switched on, the
indicator lamp in the fuel display will
light up briefly to confirm that the
system is operational.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds. RedTo confirm that the system is opera-
tional, the warning lamp in the coolant
temperature gauge will light up briefly
when the ignition is switched on.
If the lamp comes on while operating
the vehicle: the engine is overheated.
Stop and switch the engine off immedi-
ately and allow it to cool down.
Checking coolant level, refer to
page 129.
Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response to
high outside temperatures or severe
operating conditions.

Computer

Mode selectionFrom ignition key position 1 on, you can
use the button in the turn signal lever to
retrieve information from the computer
for display in the instrument cluster. By
pressing the button briefly in the direc-
tion of the steering column, you can call
up a new function for display.
The displays appear in the following
order:
Time of day, outside temperature,
average fuel consumption, cruising
range, average vehicle speed.
From ignition key position 1 on, the last
active setting is displayed.
Outside temperature You can change the units of measure
(6/7) for the outside temperature
display by pressing the right-hand reset
button in the instrument cluster while
the temperature display is active.
Ice warning If the outside temperature drops to
about 37.5 7 (+3 6), then the
computer will automatically switch to
show the outside temperature. In addi-
tion, a signal sounds as a warning and
the display flashes for a brief period.
This warning will repeat itself whenever
the temperature has climbed to at least
43 7 (+6 6) since the last warning,
and has then dropped back to 37.5 7
(+3 6).
Ice warnings do not exclude the
possibility that surface ice can still
occur at temperatures above 37.5 7
(+3 6), e. g. on bridges and shady
roads.<

The conceptThe PDC assists you when you back
into a parking space. A signal warns
you of the distance to an obstacle.
To do this, four ultrasonic sensors in
the rear bumper measure the distance
to the nearest object. The range for the
sensors located at both rear corners
ends approx. 2 ft. (60 cm) behind
the bumpers. The range for the two
middle sensors is approx. 4.9 feet
(1.50 meters).
The system is activated automatically
about one second after you engage
reverse with the ignition key in
position 2. PDC is deactivated when
you shift back out of reverse.
Acoustic signalsThe distance to the nearest object is
indicated by a tone sounding at various
intervals. As the distance between
vehicle and object decreases, the inter-
vals between the tones become
shorter. A continuous tone indicates the
presence of an object less than 1 ft.
(30 cm) away.
The warning signal is interrupted after
approx. three seconds if the distance to
the obstacle remains constant during
this time (if you are moving parallel to
a wall, for instance).
System malfunctions will be indicated
by a continuous high-pitched tone
when the system is activated the first
time. Please refer the problem to your
BMW center.The PDC does not remove the
driver's personal responsibility for
evaluating the distance between the
vehicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be
detected. This applies especially in
those cases where the system
approaches the physical limits of ultra-
sonic measurement, as occurs with tow
bars and trailer couplings, and in the
vicinity of thin and painted objects.
Certain sources of sound, such as a
loud radio, could drown out the PDC
signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they continue to operate effec-
tively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Always maintain a distance of more
than 4 in (10 cm).<

Tire Pressure Warning (RDW)The conceptThe Tire Pressure Warning system
(RDW) monitors the tire inflation pres-
sure in all four tires while driving. The
system is designed to detect whenever
the inflation pressure in a tire drops off
significantly.
By monitoring the speeds of the tires
relative to each other, a flat tire can be
detected and reported because its
speed suddenly deviates drastically
from that of the other tires.
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 correcting the
inflation pressure and letting the system
"learn" what condition is required.
1 Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 28),
and adjusting their pressure if neces-
sary
2 Turn the ignition key to position 2
3 Press button until the yellow indicator
lamp on the instrument cluster lights
up. After a little while, the indicator
lamp will go out automatically
4 After a few minutes, the RDW will
accept the current inflation pressure
as its reference value, and from that
point on, can detect and report a flat
tire.
