Close the gas 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
CHECK GAS CAP* lamp.<
Fuel tank capacity>Approx. 16.6 gal./63 liters, of which
>approx. 2.1 gal./8 liters are reserve
capacity.
Do not drive to the last drop of
fuel. This can prevent the engine
from operating properly and result in
damage.<
Fuel specificationsThe 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.<
Tire inflation pressureChecking tire pressuresTire pressures in psi/kilopascal are
shown on the driver's door post and are
visible when the door is open.
Only check the tire inflation pressures
of cold tires. This means after driving a
maximum of 1.25 miles/2 km or after
the vehicle has been parked for at least
2 hours. Warm tires have higher infla-
tion pressures.
In the following tire inflation pressure
table, all pressures are specified in the
standard units of pressure, psi and kilo-
pascal, and apply to cold tires, i.e. tires
at ambient temperature.
After correcting the tire inflation pres-
sure, reinitialize the Flat Tire Monitor so
that it can monitor the tire inflation
pressure, refer to page 87.

Check the tire pressures on a reg-
ular basis – at least twice a month
– and before every extended journey. If
this is not done, incorrect tire pressures
can cause driving instability and tire
damage, ultimately resulting in acci-
dents.<
Comply with tire approval
specificationsThe inflation pressures in the table
apply to BMW-approved tire sizes and
tire manufacturers. Your BMW center
will be glad to supply this information.
Other pressures may be required for
tires made by other manufacturers.
Your vehicle is equipped with tires
which not only meet US standards, but
also European standards. We recom-
mend the exclusive use of BMW
approved tires.Tire inflation pressure

30Opening and closing
KeysThe key set1Master keys with remote control unit
– these keys determine the functions
of the Key Memory. Refer to page 64.
You can mark the individual keys for
subsequent identification by apply-
ing the colored decals that you
received when accepting delivery of
your vehicle
In every master key with remote
control there is an extended-life
battery that is charged automatically in
the ignition lock as you drive.
For this reason, if you have a master
key with remote control that is other-
wise not used, use that key at least
once every year while driving for an
extended period to charge the bat-
tery.<
2Spare key – for storage in a safe
place, such as in your wallet. This key
is not intended for constant use. The
luggage compartment lid and the
glove compartment cannot be locked
and unlocked with this key. This is
useful for valet parking, for example.
Central locking systemThe conceptThe central locking system engages
and releases the following locks at the
same time:
>doors
>luggage compartment lid
>fuel filler door and
>glove compartment.
The central locking system is ready for
operation whenever the driver's door is
closed.
The central locking system can be
operated
>from outside via the door lock and
using the remote control
>from inside via the central locking
system button.
If it is operated from inside, the fuel
filler door will not be locked, refer to
page 34.
Operating it from outside simulta-
neously activates the anti-theft system,
which prevents the doors from being
unlocked via the door lock buttons or
the door release handles.
The central locking system unlocks
automatically in the event of an acci-
dent. In addition, the hazard warning
flashers and interior lamps come on.

31
Opening and closing – via the remote controlThe conceptThe remote control also provides two
additional functions beyond the central
locking feature:
>Switch on the interior lamps, refer to
page 32.
With this function you can also
search for your vehicle – when
parked in an underground garage, for
instance
>Open the luggage compartment lid,
refer to page 32.
The luggage compartment lid will
open slightly, regardless of whether it
was locked or unlocked.
Whenever you unlock or lock the vehi-
cle, you simultaneously deactivate/acti-
vate the anti-theft system and switch
the interior lamps on/off.
You can have a signal set to con-
firm that the vehicle's locks have
engaged securely. Since passengers or animals
remaining in the vehicle might be
able to lock the doors from the inside,
always take the vehicle's keys with you
so that the vehicle can be opened again
from the outside at any time.<
If it is no longer possible to lock
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. To pre-
vent unauthorized use of the remote
control, surrender only the spare key
when leaving the vehicle for valet park-
ing, for example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<
