Fuel specifications Tire inflation pressure The engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index
Do not use leaded fuels. The use
of leaded fuels will cause perma-
nent damage to the system's oxygen
sensor and the catalytic converter.<
Proper inflation pressures are 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).
For vehicles with Tire Pressure Control
(RDC):
After a correction of the tire inflation
pressure, reactivate the system. Refer
to page 86.460de163
Check tire inflation pressures Ð
including the space-saver spare
tire, or spare tire Ð regularly, at least
every two weeks and before beginning
a longer trip. Incorrect tire pressure can
otherwise lead to tire damage and acci-
dents.
Inflate the spare tire to the highest tire
inflation pressure specified for your
vehicle.<

Tire inflation pressureComply with tire approval
specificationsThe inflation pressures in the table
apply to tires from BMW-approved
manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
from other manufacturers. You will find
a list of approved tires sizes beginning
on page 130.
Your vehicle is equipped with tires that
meet US and European standards.
We recommend the exclusive use of
BMW-approved tires.BMW Tires
All pressure specifications in
the table are indicated in psi
(kilopascal) for cold tires
(cold = ambient temperature)

For all-season tires, use the same tire inflation pressure as for summer tires.
BMW 320i, 325i, 325xi: when using the tire 205/50 R 17 93 W extra load, the
inflation pressure increases by 3 psi (20 kilopascal).
330i/330xi: when using the tires 225/45 R 17 91 W and mixed tires 225/45 ZR 17
(front) + 245/40 ZR 17 (rear) the inflation pressure decreases by 3 psi
(20 kilopascal).

Keys1 The master keys with remote control
determine the functions of the Key
Memory. Refer to page 53
There is an extended-life battery
in every master key which is
charged automatically in the steering
lock as you drive.
For this reason, if you have a master
key that is otherwise not used, use that
key at least once a year while driving for
an extended period. This will charge the
battery. Refer also to page 35.<
2 Spare key for storage in a safe place,
such as in your wallet. This key is not
intended for continuous use46cde059
3 Door and ignition key
The locks for the luggage compart-
ment lid and the glove compartment
cannot be operated with this key Ð
this is recommended for valet
parking, for instance
Replacement keysReplacement keys are available exclu-
sively through your BMW center. Since
the keys belong to a security system
(refer to "Electronic vehicle immobilizer"
on page 33), your BMW center is obli-
gated to be sure that a person
requesting a key is authorized to do so.
If possible, take all of the master
keys that belong to the vehicle
with you when you pick up your
replacement key.
When you receive a new replacement
key, turn that key to position 2 in the
ignition lock once (ignition switched on)
and then back. This allows the elec-
tronic vehicle immobilizer to "learn" the
new key.<

Central locking system Opening and closing Ð from the outside The conceptThe central locking system is ready for
operation whenever the driver's door is
closed. The system engages and
releases the locks on the
>doors,
>luggage compartment lid and
>fuel filler door.
The central locking system can be
operated
>from outside via the door lock and
using the remote control
>from inside by pressing a button.
Activating it from inside does not lock
the fuel filler door (see page 38). When
the system is actuated from the
outside, the antitheft system is acti-
vated simultaneously. Both the door
locks and the safety lock buttons
remain locked. The alarm system is also
armed or disarmed.
If locked from the inside, the central
locking system unlocks automatically in
the event of an accident. In addition,
the hazard warning flashers and interior
lamps come on.
Using the keyOne turn of the key in the driver's door
lock unlocks the driver's door only.
Turning the key a second time unlocks
all of the remaining doors, the luggage
compartment lid and the fuel filler door.
You can have a confirmation
message set to inform you that the
vehicle has been properly locked.<460de006
Convenience operating modeYou can also operate the power
windows and sliding/tilt sunroof via the
door lock.
>To open: with the door closed, turn
the key to the "Unlock" position and
hold it.
>To close: with the door closed, turn
the key to the "Lock" position and
hold it.
Watch during the closing process
to be sure that no one is injured.
Releasing the key stops the opera-
tion.
Turn the key to the extreme left or right
to unlock/lock the door.

Opening and closing Ð from the outsideUsing the remote control The remote control makes opening and
locking the doors of your vehicle very
convenient. Furthermore, it provides
two additional functions that can only
be executed by means of the remote
control:
>Switch on the interior lamps, refer to
page 36.
With this function, you can also
"search for" your vehicle Ð when
parked in an underground garage, for
instance.
>Open the luggage compartment,
refer to page 37.
The luggage compartment lid will
open slightly, no matter whether it
has been locked or unlocked.
The anti-theft system is also deacti-
vated simultaneously when you unlock
the vehicle, the alarm system is
disarmed, and the interior lamps are
turned on. When you lock the vehicle,
the systems are activated and armed,
and the lamps go off.
You can have a confirmation
message set to inform you that the
vehicle has been properly locked.<
Master keysKeys with remote control are master
keys. Refer to page 32.
Children might be able to lock the
doors from the inside. For this
reason, always take the vehicle keys
with you so that the vehicle can be
opened again from the outside at any
time.<460de494
Master keys that are used repeat-
edly are always ready for opera-
tion since the battery in the transmitter
is charged automatically in the steering
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 charge the battery. Refer also
to page 32.
To prevent unauthorized use of the
remote control, surrender only the door
and ignition key or the spare key (refer
to page 32) when leaving the vehicle for
valet parking, for example.
In the event of a system malfunction,
please contact your BMW center.
You can also obtain replacement keys
there.<

To closeThe handle recesses in the interior trim
panel of the luggage compartment lid
(arrows) make it easier to pull the lid
down.
To avoid injuries, be sure that the
travel path of the luggage
compartment lid is clear when it is
closed, as with all closing procedures.<460de067
Do not drive with the luggage
compartment lid open, since
exhaust fumes could penetrate the inte-
rior of the vehicle. Should it be abso-
lutely necessary to operate the vehicle
with the luggage compartment lid open:
>Close all windows and the sliding/tilt
sunroof.
>Increase the air supply for the air
conditioner or the automatic climate
control to a high level. Refer to
page 92 or 98.<
