Fuel quality 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.<
You will find the tire inflation pressures
on the door pillar (visible with door
open).Check tire pressuresAll pressure specifications are indicated
in psi (kilopascal) for cold tires at
ambient temperature (refer also to the
next page).
Remember to reactivate the Flat
Tire Monitor after every wheel or
tire change, refer to page 67.<520de008
Check tire inflation pressures
regularly Ð at least every two
weeks and before each extended
journey. Otherwise, incorrect tire pres-
sure can lead to poor handling, tire
damage and accidents.<
Comply with tire approval
specificationsThe inflation pressures in the table
apply to tires made by BMW-approved
manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
made by other manufacturers.
You will find a list of approved tire sizes
on page 104.
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.

Electronic vehicle immobilizer The key to securityThe electronic vehicle immobilizer
reduces your BMW's susceptibility to
theft by rendering it impossible to start
the engine using any means other than
the car's own individual keys. The
system operates automatically, with no
action or intervention on your part. Your
BMW center can cancel the system
authorization for individual keys (for
instance, if a key is lost). A deactivated
key can no longer be used to start the
engine.520de146
Advanced electronics in actionAt the heart of this system is an elec-
tronic chip that is integrated into the
key. The lock mechanism itself is actu-
ally a dual-function device, simulta-
neously serving as a communications
interface designed to allow the security
system to maintain a continuous stream
of variable, vehicle-specific signals with
the electronic circuitry in the key. The
system will release the ignition, elec-
trical steering lock, fuel injection and
starter for use only if it detects an
"authorized" key.
Exposure to external force can
damage the key's integrated elec-
tronic circuitry and render it inoperative.
A damaged key can no longer be used
to start the engine or release the
steering lock.<

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
>fuel filler door
>glove compartment
>cellular phone holder.
The central locking system can be
operated
>from the outside via the driver's door
lock or by using the remote control
>from the inside by pressing a button.
If you initiate central locking from
inside, neither the fuel filler door, the
glove compartment, nor the cellular
phone holder are locked (refer to
page 36).
If you do set it from outside, the anti-
theft alarm is automatically activated as
well. This prevents the door handles
from unlocking the doors. The alarm
system is also activated or deactivated.
The central locking system unlocks
automatically in the event of an acci-
dent. In addition, the hazard warning
flashers and interior lamps come on.
Using the keySwing the door lock mechanism's cover
upward. Return it to its original position
and allow the detent to engage when
you have finished locking or unlocking
the doors.
Turn the key in the driver's door once to
unlock the driver's door only; turning
the key a second time will unlock the
passenger door, the luggage compart-
ment lid, the fuel filler door, the glove
compartment, and the cellular phone
holder.
If necessary, you can open the fuel filler
door by pressing the button inside the
vehicle; refer to page 25.520de100
You can have various signals set
as an acknowledgment message
when locking.<
Convenience operationYou can also operate the windows 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.
As the windows are closing you
should always monitor their path
and progress to ensure that no injuries
occur. Release the key to stop the
windows. Turn the key to the extreme left or right
to unlock/lock the driver's door.
Refer to page 143 for operating the
passenger door.

Opening and closing Ð from the inside Use this button to operate the central
locking system when the doors are
closed. The doors and the luggage
compartment lid are unlocked or locked
only. The anti-theft alarm system is not
activated.
You can also have the key preset
to engage the central locking
system as soon as you start to drive.<520de011
If only the driver's door was
unlocked from the outside and
you press the button,
>the passenger door, the luggage
compartment lid, the fuel filler door,
the glove compartment and the
cellular phone holder will be
unlocked, when the driver's door is
open
>the driver's door will be locked again
if it is closed.<
To unlock and open the doors>Either unlock the doors together with
the button for the central locking
system and then pull each of the
release handles above the armrests
or
>pull the release handle for each door
twice: the first pull unlocks the door,
and the second one opens it.To engage the locks>Lock both doors using the button for
the central locking.
Because passengers or animals
remaining in the vehicle could lock
the doors from the inside, you should
always remove the key and take it with
you to ensure that you remain able to
unlock the vehicle from the outside at
all times.<

1 Odometer With the ignition key in position 0, you
can activate the displays shown in the
illustration by pressing the button in the
instrument cluster (arrow).2 Trip odometerTo reset the trip odometer to zero,
press the button (arrow) with the igni-
tion key in position 1 and up.520us004
Never allow engine speed to climb until
the needle enters the tachometer's red
sector.
To protect the engine, the engine-
management system automatically
interrupts the fuel supply in this range,
producing the sensation of a sudden
loss of power.520de029
When you switch on the ignition, the
indicator lamp lights up briefly to
confirm that the system is operational.
Once the indicator lamp comes on and
stays on, there are approx. 2.5 gallons
(10 liters) of fuel left in the fuel tank.
For fuel tank capacity, refer to
page 161.
Certain operating conditions (such
as those encountered in mountainous
areas) may cause the needle to fluc-
tuate slightly.
Please refuel early, since driving
to the last drop of fuel can result
in damage to the engine or catalytic
converter.<520us005

Brakes:
Do not rest your foot on the brake
pedal while driving. Even light but
consistent pressure on the brake pedal
could lead to high temperatures, brake
wear, and possibly, to brake system
failure.
Aquaplaning:
Reduce speed while driving on wet or
slushy roads, otherwise, a wedge of
water can form between the tires and
the road surface. This phenomenon is
referred to as "aquaplaning" or "hydro-
planing." It is characterized by a partial
or complete loss of contact between
the tires and the road surface. The ulti-
mate results are loss of steering and
braking control.
Driving through water:
When there is water on the roads, do
not drive in it if it is deeper than 1 ft
(30 cm), and even then, only at walking
speed, otherwise the vehicle can
sustain damage to the engine, the elec-
trical systems and the transmission.<
The catalytic converter reduces harmful
exhaust emissions.
It is designed for use with unleaded fuel
only. Even minute quantities of lead
would be enough to permanently
damage both the catalytic converter
and the system's oxygen sensor.
To ensure efficient, trouble-free engine
operation and to avoid potential
damage:
>Be sure to comply with the scheduled
maintenance requirements
>Fill the fuel tank well before it is empty
>Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, unburned residual
fuel could ignite on the way to the
catalytic converter and cause
damage. It is better to start the
vehicle with a battery charger or
assistance from another vehicle
>Avoid other situations where the fuel
is either not burned or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never allow the engine to run with
any of the spark plug cables discon-
nected.Be sure to comply with the
instructions above to prevent
unburned fuel from reaching the cata-
lytic converter. Otherwise, there is the
danger of overheating and damage to
the catalytic converter.
Extreme temperatures are present with
the catalytic converter both on this and
every catalyst-equipped vehicle. Heat
shields are installed adjacent to some
sections of the exhaust system. Never
remove these shields; do not apply
undercoating to their surfaces. When
driving, standing at idle, and parking
the vehicle, take care to avoid contact
between the exhaust system and flam-
mable materials (grass, hay, leaves
etc.). Such contact could start a fire,
resulting in serious personal injury and
property damage.<
