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.<
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.

Vehicles with Flat Tire Monitor:
After correcting the inflation pressures,
reinitialize the system. Refer to
page 92.
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
accidents.
Remember to check the inflation pres-
sure in the space-saver or standard
spare tire.
Inflate the spare tire to the highest infla-
tion pressure specified for your vehi-
cle.
specificationsThe inflation pressures in the table
apply to BMW approved tire sizes and
tire manufacturers. Your BMW center
can provide you with more information
about these. Other pressures may be
required for tires made by other manu-
facturers.
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.

32Opening 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 there is an
extended-life battery that is
charged automatically in the ignition
lock as you drive.
For this reason, if you have master keys
that are not being used otherwise, use
those keys at least once a year while
driving for an extended period to
charge the battery.<
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 is ready for
operation whenever the driver's door is
closed. The system simultaneously
engages and releases the locks on the
>doors
>luggage compartment lid
>fuel filler door.
The central locking system can be
operated
>from outside via the remote control
as well as via the driver's door lock
>from inside by pressing a button.
The fuel filler door is not locked when
the central locking system is activated
from the inside, refer to page 37. When
the system is actuated from the out-
side, the anti-theft system is also acti-
vated. This prevents the doors from
being unlocked via the lock buttons or
the release handle. The alarm system is
also activated or deactivated.
If locked from the inside, the central
locking system unlocks automatically in
the event of an accident, except on
doors that have been locked individu-
ally using the lock buttons, refer to
page 39. In addition, the hazard warn-
ing flashers and interior lamps come on.
