are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react in the follow-
ing section.

If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

<

●

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level; top off as
required. If the oil level is correct:
please contact the nearest BMW cen-
ter.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

RefuelingFuel filler door
Always switch off the engine
before refueling, as it is not possi-
ble to add fuel with the engine running,
and attempts may also trigger the SER-
VICE ENGINE SOON lamp.<
Press on the rear edge of the fuel filler
door to open and close it.
If an electrical malfunction occurs, you
can unlock the fuel filler door manually:
1. Undo the trim panel on the right side
of the luggage compartment
2. Pull the button with the fuel pump
symbol.
Always observe all safety precau-
tions posted at the service station
when handling fuel.
Never carry spare fuel containers in
your vehicle. Whether empty or full,
these containers can leak, cause an
explosion, or lead to fire in the event of
a collision.<
Simple and environmentally
friendly
Open the filler cap carefully to
prevent fuel from spraying out.
Fuel spray may cause injury.<
Keep the filler cap in the bracket – see
arrow – attached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refuel-
ing
>results in premature pump shutoff
>and will reduce the effectiveness of
the vapor recovery system on the
pump.
The fuel tank is full when the filler noz-
zle shuts off the first time.

Close the fuel filler 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 FILLER 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 pressureThe specified inflation pressures are
provided on a sticker attached to the
B-pillar and are visible with the driver's
door open.Checking tire pressuresAll pressures are specified in the stan-
dard units of pressure, psi and kilopas-
cal, and apply to cold tires, that is tires
at ambient temperature. Refer to tire
pressure table at the end of this chap-
ter.
Vehicles with Tire Pressure Monitor
(TPM)/Flat Tire Monitor:
After correcting the inflation pressures,
reinitialize the system, refer to
pages 92, 93.

To avoid placing unnecessary loads on
the battery, you should avoid operating
the top when the engine is switched off.
1. Read and comply with the preceding
safety precautions
2. Before opening the convertible top,
ensure that the convertible top com-
partment panel is back down into its
original position, refer to page 37
3. Ensure that the luggage compart-
ment lid is closed
4. Maintain pressure on the corre-
sponding button for the convertible
top operation.
The red indicator lamp flashes when-
ever the convertible top mechanism
is in operation. It goes out when the
opening or closing process has been
completed.
If it continues flashing after the con-
trol button is released, the process
has not completed opening or clos-
ing. You can resume operation in the
desired direction by pressing the
button again.
If the yellow indicator lamp lights up
continuously with the button
pressed, the convertible top com-
partment panel has been raised and
the top cannot be moved, refer to
step 2.
The convertible top stops moving
immediately when the button is
released. You can resume operation in
the desired direction by pressing the
button again.<
While the convertible top is in
motion, the rear window will move
toward the passenger compartment. To
avoid possible pinching, the area
around the closing convertible top
should be clear.<
The side power windows are lowered a
small distance whenever the top is set
in motion by pressing the button and
after the opening or closing process is
completed, they will go back up, if you
keep holding the button down for more
than 2 seconds after the indicator lamp
has gone out.
The luggage compartment lid cannot be
opened while the convertible top is in
motion.
Do not close the side power win-
dows using the buttons if the con-
vertible top operation has been inter-
rupted.<
After having been stored for an
extended period of time in the
convertible top compartment, e.g. dur-
ing the winter months because the
hardtop was being used, you may have
to support the convertible top by hand
when closing it for the first time: If the
convertible top should halt just before

Vehicle Memory, Key MemoryHow the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own individ-
ual preferences. In engineering your
vehicle, BMW has provided for a num-
ber of options for personal adjustment
that can be programmed into your vehi-
cle at your BMW center.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle –
Vehicle Memory – or the individual –
Key Memory. Provided that each per-
son has a separate remote-control key,
you can have your BMW center enter
basic adjustment data for up to four
individuals in the system.
The system then relies on a bilateral
data exchange to identify the individual
user and executes the selected settings
whenever the remote control unit is
used to disengage the door locks.
Color-coded decals have been pro-
vided to help you distinguish individual
keys with different settings.What the system can doYour BMW center can provide you with
details on the capabilities of the Vehicle
Memory and Key Memory systems.
Examples for Vehicle Memory:
>Various signals as acknowledgment
when locking or unlocking your vehi-
cle, refer to pages 31, 33
>Activates/deactivates the "Follow me
home" function, refer to page 96
>Activates/deactivates daytime driv-
ing lamps, refer to page 96
>Sets the units of measure for display-
ing time, outside temperature, dis-
tance traveled and fuel consumption
in the instrument cluster>Indicates via an acoustic tone that
PDC has been activated, refer to
page 87
>Switches on rear window defroster
automatically, refer to
pages 102, 107
>After giving an ice warning, the dis-
play returns to the previous setting,
refer to page 85.
Examples for Key Memory:
>Unlocks driver's door first, then the
vehicle's remaining locks, refer to
page 33
>Locks the vehicle automatically after
you start off, refer to page 34
>Automatically adjusts the driver's
seat to the personal programmed
settings when the vehicle is
unlocked, refer to page 57
>Automatic tilting of the passenger-
side mirror, refer to page 58.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<
