Tire inflation pressures If the driver's door is open, the infla-
tion pressures are also visible on the
door pillar. Inflation pressures are
indicated in psi (bar) with tires cold
(ambient temperature).
The inflation pressures apply to tires
from BMW-approved manufacturers;
your BMW Retailer will provide you
with this information. Higher pres-
sures may be required for tires from
other manufacturers.a
Periodically check the inflation
pressure Ð also of the spare tire Ð at
least twice each month and before
setting out on an extended trip. Failing
this, incorrect tire pressure may ren-
der the car unstable or cause tire
damage resulting in an accident.cSedan models

1 Master key with battery-powered
lamp (switch on by pressing the BMW
symbol).
2 Master key without lamp.
3 Spare key to be kept in a safe place
e. g. in your wallet. This key is not
intended for continuous use.
4 Door and ignition key
This key does not operate the locks
for the glove compartment and the
luggage compartment. This is useful
e. g. at a hotel.The electronic vehicle immobilization
unit increases the anti-theft protection
of your BMW Ð without additional
adjustment or activation of systems.
This electronic immobilization system is
designed to reduce the susceptibility of
the vehicle to theft by making it impos-
sible to start the engine using any
means other than the special keys fur-
nished with the vehicle.
The system features an electronic chip
integrated within the key as a supple-
ment to the conventional mechanical
locking system.
The lock mechanism itself is actually a
dual-function device, simultaneously
serving as a communications interface
designed to allow the car security sys-
tem to maintain a continuous stream of
variable, vehicle-specific signals with
the electronic circuitry in the key. The
ignition, the flow of fuel and the starter
are enabled only after the key has been
recognized as "authorized".
b
External force can damage the
electronic circuitry integrated in the key.
Such a key can no longer be used to
start the engine.c
Replacement of a keyReplacement keys are available exclu-
sively through your authorized BMW
Retailer, who is also under obligation to
request verification of vehicle owner-
ship before issuing a substitute key.
Your BMW Retailer can also cancel or
restore the electronic system authoriza-
tion for individual keys (e.g., if a key is
lost). A deactivated key can no longer
be used to start the engine.For US owners onlyThe transmitter and receiver units com-
ply with Part 15 of the FCC (Federal
Communication Commission) Regula-
tions. Operation is governed by the fol-
lowing:
FCC ID: LXBEWS
As defined in the regulations, such a
device is not to emit significant interfer-
ence and must also be shielded against
interference from external sources to
prevent unauthorized or inadvertent
activation.a
Any unauthorized modifications
or changes to these devices could void
the userÕs authority to operate this
equipment.c

gage compartment lock with a key
unlocks or locks the following:

Never use the keys or the remote
control* to lock an occupied vehicle, as
it would then be impossible to unlock it
from inside.c
Convenience closing
* for power win-
dows and sliding/tilt sunroof: after clos-
ing the doors, hold the key in the lock
position to close the windows and slid-
ing/tilt sunroof. The windows/sunroof
stop moving immediately when you
release the key. To be able to keep the
closing system in view, convenience
closing can only be activated via the
driver's door lock for safety reasons,
even on vehicles with remote control.
Emergency lock operation(in the event of electrical failure)
Turn the key to the end positions of the
door lock to unlock/lock the respective
door.
Activating the central locking
system from inside the vehiclePressing the lock button of a front door
unlocks/locks the doors and luggage
compartment, but does not arm the
alarm system.b
If the vehicle is locked from the
inside with this lock button, the fuel
filler door remains unlocked to allow
refueling. On the BMW Convertible, the
glove compartment also remains un-
locked to allow for its use.
It is also possible to unlock the car from
the inside by pulling on one of the front
door handles.c
To preclude accidental locking of the
vehicle
dit can not be locked with the lock
button when the driver's door is open
dthe safety button of the passenger
door activates the central locking
system only when both front doors
are locked.
