Refueling Fuel specificationsFuel filler doorPress on the rear edge of the fuel filler
door to open and close it.
To unlock the fuel filler door if there is a
malfunction of the central locking sys-
tem, refer to page 156.
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 explo-
sion, or lead to fire in the event of a col-
lision.< 460de004
Simple and environmentally
friendly
Open the fuel filler cap carefully.
If you do not, fuel could spray out.
Fuel spray may cause injury.<
Keep the filler cap in the bracket at-
tached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refuel-
ing
>results in premature pump shutoff
>and will reduce the effect of the vapor
recovery system on the pump.
Close the fuel cap carefully after
refueling. A loose or missing cap
will activate the Service Engine Soon
warning lamp.<
460de005
Use unleaded gasoline only.
Recommended fuel: Premium with a
minimum octane rating of 91 AKI.
BMW engines are equipped with knock
sensors and will adapt automatically to
different octane ratings, provided that
the minimum octane requirement
(87 AKI) is met.
Fuels with higher octane ratings will pro-
vide enhanced performance and lower
fuel consumption, while the use of fuels
with lower octane ratings will have the
opposite effect.
Do not use leaded fuels. The use of
leaded fuels will cause permanent
damage to the system's oxygen sensor
and the catalytic convertor.<
AKI = Anti Knock Index

Electronic vehicle immobilizer The key to securityYour BMW is equipped with a passive
anti-theft system. This electronic immo-
bilization system is designed to reduce
the susceptibility of the vehicle to theft
by making it impossible to start the
engine using any means other than the
special keys furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for individual
keys (in the event of loss, for instance). A
deactivated key can no longer be used
to start the engine.463de042
How the electronics workAt the heart of this system is an elec-
tronic chip that is integrated into the
key. The lock mechanism itself is actu-
ally a dual-function device, simulta-
neously serving as a communications
interface designed to allow the security
system to maintain a continuous stream
of variable, vehicle-specific signals with
the electronic circuitry in the key. The
system will not release the ignition, fuel
injection and starter unless it recog-
nizes an "authorized" key.
Force applied to the key can dam-
age the integrated electronic cir-
cuitry. A damaged key can no longer be
used to start the engine.<

0 Steering lock engaged The key can only be inserted or re-
moved in this position.
After removing the key, turn the steer-
ing wheel slightly to the left or right until
the lock engages.
If the key is not removed, an acoustic
signal is sounded after the driver's door
has been opened.
Vehicles with automatic transmis-
sion:
Do not move the selector lever from the
"Park" position until the engine is run-
ning (ignition key at position 2).
In order to turn the key back to position
0 or to remove it, move the selector
lever into position "Park" first (Inter-
lock).<460de022
1 Steering lock disengaged Turning the steering wheel slightly to
the right or left often makes it easier to
turn the key from 0 to 1.
Individual electrical devices are ready
for operation.2 Ignition onAll electrical equipment and accesso-
ries are available for use.3 Starting the engine
Vehicles with manual transmis-
sion: Depress the clutch when
starting the vehicle. A lockout prevents
the engine from starting if the clutch is
not depressed.c
Before starting>Engage the parking brake.
>Be sure that the shift lever is in "Neu-
tral" (or "Park" if the vehicle is equipped
with an automatic transmission).
>Manual transmission: Depress the
clutch pedal.
>Automatic transmission: Depress the
footbrake.
Do not run the engine in enclosed
areas. The exhaust gases contain
carbon monoxide, an odorless and col-
orless, but highly toxic gas. Breathing
the exhaust gases poses an extreme
health risk, and can lead to uncon-
sciousness and death.
Do not leave the car unattended with
the engine running. An unattended vehi-
cle with a running engine represents a
potential safety hazard.<
>Start the engine. Do not press the
accelerator pedal.
Do not actuate the starter for too
short a time, but not turn it for more
than approx. 20 seconds. Release the
ignition key immediately when the
engine starts.
Do not allow the engine to warm up by
leaving it running while the vehicle remains
stationary. Instead, begin driving immedi-
ately at a moderate engine speed.<

Starting the engine Switching off the engine If the engine does not start on the first
attempt (if it is very hot or cold, for in-
stance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold start at extremely low tempera-
tures, from approx. + 5 7 (Ð 15 6)
and at elevations above 3,300 feet
(1,000 meters):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds)
>Press the accelerator pedal halfway
down while engaging the starter.Turn the ignition key to position 1 or 0.
Do not remove the ignition key
while the vehicle is still moving.
If you did so, the steering lock would
engage when the steering wheel is
turned.
When you leave the vehicle, always re-
move the ignition key and engage the
steering lock.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined sur-
faces. Placing the lever in 1st gear or
reverse may not provide adequate
resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<

Automatic transmission with Steptronic
*
You have the option of driving with a
normal automatic transmission or
switching to manual.
When you move the selector lever from
the "D" position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. As soon as you briefly
touch the selector lever in the "+" or "Ð"
direction, Steptronic changes the gear.
The manual mode is engaged. When-
ever you want to use automatic again,
just shift the selector lever toward the
right to position D.
The automatic transmission with Step-
tronic is equipped with ATC (Adaptive
Transmission Control). ATC reacts with
precision to your individual driving style
and the current driving conditions. It is
for this reason that various shift pro-
grams are used.
For additional details concerning the
ATC, please refer to the chapter de-
scribing "Advanced technology" on
page 162.
Selector lever positions
P R N D M/S + Ð
Starting the engineThe engine can only be started in selec-
tor lever positions P ("Park") or N ("Neu-
tral").Range selectionA detent prevents inadvertent shifts into
certain selector lever positions. To dis-
engage the detent, press the button on
the front of the shift knob (arrow).460de076
While the vehicle is stationary and
before shifting out of "Park" or
"Neutral," depress the footbrake in
order to disengage the selector lever's
lock mechanism (Shiftlock).
Hold the footbrake down until starting
off. Otherwise the vehicle will "creep"
when a drive position is engaged.<
If you leave the vehicle with the
engine running, move the selector
lever to the "Park" or "Neutral" position
and apply the parking brake. If you fail
to do this, the vehicle could move. Do
not leave the car unattended with the
engine running. An unattended vehicle
with a running engine represents a po-
tential safety hazard.<

ary. The transmission locks to prevent
the rear wheels from turning.R ReverseSelect only when the vehicle is station-
ary.N NeutralSelect only if your journey is interrupted
for a long period.

Automatic transmission with Steptronic
*
In the following situations, the Step-
tronic "thinks" for you in the manual
mode:
>In order to prevent the engine from
overrevving, the transmission shifts
automatically to the next higher gear
just before the RPM cutoff point.
>If you do not do anything to inter-
vene, it will automatically downshift
at lower speeds.
>In kickdown, it will downshift into
the lowest gear possible, depending
on the engine speed.
>According to the situation, for in-
stance in wintry conditions, the
vehicle can be started in 2nd or
3rd gear.
