Fuel specifications Tire inflation pressuresRefuel with lead-freeThe engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI
AKI = Anti Knock Index
Never use leaded fuel, as it would
cause permanent and irreversible
damage to the oxygen sensor and the
catalytic converter.<
The specified inflation pressures are
provided on a sticker attached to the
B-pillar and visible with the driver's
door open.Check tire pressuresOn the next page you will find all the tire
pressure and ambient air temperature
specifications stated in the units usually
used in your country (psi; kilopascal).
After correcting the tire inflation pres-
sure, reinitialize the Flat Tire Monitor so
that it can monitor the tire inflation
pressure, refer to page 77.
Check the tire pressures on a
regular basis Ð at least twice a
month Ð and before every extended
journey. Incorrect tire pressure can
otherwise lead to driving instability, tire
damage and accidents.<
Comply with tire approval
specifications The inflation pressures apply to BMW
approved tire sizes and tire manufac-
turers. Your BMW center is familiar with
these pressures. Higher pressures may
be specified for tires made by other
manufacturers.
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.

Opening and closing Ð via the remote control The conceptThe remote control gives you an excep-
tionally convenient method for
unlocking and locking your vehicle.
Furthermore, it provides two additional
functions which you can only execute
via the remote control:
>Switch on the interior lamps, refer to
page 31.
With this function, you can also
"search for" your vehicle Ð when
parked in an underground garage, for
instance
>Open the luggage compartment lid,
refer to page 31.
The luggage compartment lid will
open slightly, regardless of whether it
was locked or unlocked.
The anti-theft system is also deacti-
vated/activated simultaneously with the
unlocking or locking of the vehicle, the
alarm system is disarmed/armed, and
the interior lamps are switched on/off.
You can have a signal set to
confirm that the vehicle's locks
have engaged securely.<
1 Unlock, convenience mode opening
and alarm system
2 Lock and secure, switch on interior
lamps, deactivating tilt alarm sensor
and interior motion sensor
3 Open the luggage compartment lid,
panic mode (trigger alarm)
Master key with remote control
Since passengers or animals
remaining in the vehicle might be
able to lock the doors from the inside,
take the vehicle's keys with you so that
the vehicle can be opened again from
the outside at any time.<
Master keys that are used repeat-
edly are always ready for opera-
tion, since the battery in the key is
charged automatically in the ignition
lock as you drive.
If it is no longer possible to unlock the
vehicle via the remote control, the
battery is discharged. Use this key
while driving for an extended period in
order to recharge the battery, refer also
to page 28.
Guard the remote control against unau-
thorized use by only surrendering the
spare key or the door key (refer to
page 28) e.g. for valet parking.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Alarm system
*
The conceptThe vehicle alarm system responds:
>When a door, the hood or the
luggage compartment lid are opened
>To movement inside the vehicle (inte-
rior motion sensor)
>To variations in the vehicle tilt, 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 acoustic alarm for
30 seconds
>Activating the hazard warning
flashers for approx. five minutes
>Flashing the high beams on and off in
rhythm with the hazard warning
flashers.
To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
by using a key or the remote control,
the alarm system is also simultaneously
armed or disarmed.
You can have a signal set as
acknowledgment for both arming
and disarming the alarm.<
You can also open the luggage
compartment lid when the system is
armed by pressing the button of the
remote control, refer to page 31. When
it is closed, the lid is once again
secured.
Indicator lamp displaysThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes
continuously: the system is armed
>The indicator lamp flashes when it is
armed: the door(s), the hood or
luggage compartment lid are not
completely closed. Even if you do not
close the alerted area, the remaining
areas are secured, and the indicator
lamp flashes continuously after
10 seconds. However, the interior
motion sensor is not activated
>If the indicator lamp goes out when
the system is disarmed: no manipula-
tion or attempted intrusions have
been detected in the period since the
system was armed

Alarm system
*
>If the indicator lamp flashes for
10 seconds when the system is
disarmed: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.Avoiding unintentional alarms The tilt alarm sensor and interior motion
sensor can be deactivated together.
Doing this prevents a false alarm from
being triggered, e.g. in garages with
elevator ramps or when the vehicle is
being transported on a car train:
Lock the vehicle twice (= arm the
system). Press button 2 on the remote
control twice in succession or lock the
vehicle twice with the key, refer to
page 31.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated as long as the system is
armed.
Arm the alarm system again to reacti-
vate the tilt alarm sensor and the inte-
rior motion sensor.
Interior motion sensorIn order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
Nevertheless, you should deactivate
the interior motion sensor (refer to
"Avoiding unintentional alarms") if you
>leave children or animals in the
vehicle
>the windows or sliding/tilt sunroof
should be left open.

Manual transmission Sequential M gearbox
* SMG II
Reverse Select only when the vehicle is
completely stopped. Press the gearshift
lever to the left to overcome the slight
resistance.
As you do this, the backup lamps will
come on automatically when the igni-
tion key is in position 2.
Do not hold the vehicle in place on
slopes by slipping or "riding" the
clutch. Use the parking brake instead.
Riding the clutch causes the clutch
assembly to wear out sooner.<
The conceptThe sequential M gearbox SMG II is an
automated manual gearbox with which
clutching and shifting is assumed by an
electro-hydraulic system.
The SMG II is operated via two shift
paddles on the steering wheel and the
selector lever in the center console.
It offers the following functions:
>Sequential and automated shifting
mode
>Ability to choose between different
driving programs (Drivelogic)
>Gradient assistance
>Upshift display (shift lights)
>Throttle blip
>Driving dependent functions:
The respective driving situation (e.g.
cornering, mountain driving, braking)
is detected by sensors and taken into
account accordingly for shifting, e.g.
to achieve optimum gear selection
during deceleration and subsequent
acceleration>Slip recognition at the rear axle for
increasing driving stability, e.g.
during downshifting on slippery road
surfaces
>Operating safety through protection
against misshifting.

Sequential M gearbox* SMG IIShifting gears with shift paddles on
steering wheel:
>To upshift, briefly pull the right
paddle "+"
>To downshift, briefly pull the left
paddle "Ð."
Shift paddles with various widths
matched to the shape of your
hand are available from your BMW
center.<
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward "+"
>To downshift, push the selector lever
forward "Ð".
No automatic upshifting is carried out in
the sequential mode.
You accelerate from higher gears, e.g.
during passing, by manually down-
shifting.
In the following situations the SMG II
helps you "think" in the sequential
mode:
>Upshifts and downshifts are only
executed when the new gear will
provide a suitable combination of
vehicle and engine speed, i.e., down-
shifts that would cause the engine to
overrev will not be executed
>During a stop the gearbox is auto-
matically downshifted into the first
gear so that, e.g. before a traffic light,
it is only necessary to accelerate to
continue driving
>When the speed is reduced, the
gearbox is automatically down-
shifted shortly before a gear-depen-
dent minimum speed is reached
without you taking any action.
A Ð Automated modeEach time the engine is started, the
automated mode is activated as soon
as you move the selector lever into the
forward driving position.
In the automated mode all forward
gears are automatically shifted.
Changeover from sequential to auto-
mated mode: tap the selector lever to
the right toward "A." Watch the display
in the instrument cluster, refer to
page 61.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely (kick-down). The gearbox
now downshifts in dependence on the
selected driving program.
Even in the automated mode, you can
help specify the shifting point: if a gear-
dependent minimum speed is
exceeded, you can upshift by slowly
reducing pressure on the accelerator
pedal. In the process, the respective
driving situation is detected by sensors
and taken into account.

depending on road speed.
Rain sensor

The rain sensor is located on the wind-
shield directly behind the rearview
mirror.
To activate the rain sensor:
>With the ignition key in position 1
or higher, move the lever to
position 1. The wipers will make at
least one sweep across the wind-
shield
>You can leave the lever in position 1
at all times. With the ignition key in
position 1 or higher, all you then need
to do to activate the rain sensor is
briefly turn the rotary dial 5.
To adjust the sensitivity of the rain
sensor: turn rotary dial 5.
To deactivate the rain sensor: return
lever to position 0.
Deactivate the rain sensor in auto-
matic car washes. Failure to do so
could result in damage caused by
undesired wiper activation.<
Normal wiper speedWhen the vehicle is stationary, the
wipers switch automatically to intermit-
tent wipe (not on vehicles with rain
sensor).Fast wiper speedWhen the vehicle is stationary, the
wipers operate at normal speed (not on
vehicles with rain sensor).
