Notes

For your own safety
Maintenance and repair

Advanced technology, e.g. the
use of modern materials and high-
performance electronics, requires spe-
cially adapted maintenance and repair
methods. Therefore, only have corre-
sponding work on your BMW carried
out by a BMW center or a workshop
that works according to BMW repair
procedures with correspondingly
trained personnel. If work is carried out
improperly there is a danger of conse-
quential damage and the related safety
risks.

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
SERVICE 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:
Pull the knob with the fuel pump symbol
on the right trim panel of the luggage
compartment.
When handling fuels, comply with
all of the applicable safety precau-
tions posted at the service station.
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.<
Please observe while refuelling
Open the gas cap carefully to pre-
vent fuel from spraying out. Fuel
spray may cause injury.<
Place the gas cap in the bracket
attached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Lifting the
nozzle during refueling
>results in premature pump shutoff
>and will reduce the effect of the vapor
recovery system on the pump.
The fuel tank is full when the filler noz-
zle shuts off the first time.

25
Closing the gas capPlace the cap in position and turn it
until a clearly audible click is heard.
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.<
Warning lamp* lights up. The
gas cap is not properly closed
or is missing. Check if the gas
cap is properly closed.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 fuelPremium Unleaded Gasoline,
Minimum Octane Rating: AKI 91.
Minimum Octane Rating corresponds to
the Anti Knock Index AKI and is deter-
mined according to the so-called
(R+M)/2 method.
Do not use leaded gasoline, as
otherwise the lambda probe and
catalytic converter will be permanently
damaged.<Use high-quality brandsField experience has indicated signifi-
cant differences in fuel quality: volatility,
composition, additives, etc., among
gasolines offered for sale in the United
States and Canada. Fuels containing up
to and including 10 % ethanol or other
oxygenates with up to 2.8 % oxygen by
weight, that is, 15 % MTBE or 3 % meth-
anol plus an equivalent amount of co-
solvent, will not void the applicable
warranties with respect to defects in
materials or workmanship.
The use of poor-quality fuels may
result in drivability, starting and
stalling problems especially under cer-
tain environmental conditions such as
high ambient temperature and high alti-
tude.
Should you encounter drivability prob-
lems which you suspect could be
related to the fuel you are using, we
recommend that you respond by
switching to a recognized high-quality
brand.
Failure to comply with these recom-
mendations may also result in unsched-
uled maintenance.<

Driving when the opening or clos-
ing process has not been com-
pleted can cause vehicle damage or
personal injuries.
Do not reach into the convertible top
mechanism during opening and closing.
Keep children away from the moving
parts of the convertible top during
operation.<
If possible, only operate the con-
vertible top with the vehicle
stopped, as otherwise the process may
be interrupted.
If you set the convertible top in motion
with the vehicle stationary and then
have to start suddenly – for instance, at
a traffic light – you can still complete
the operation by driving as slowly as
possible and again pressing and main-
taining pressure on the button.<
To close the electric power win-
dows while driving, always be
sure to first close either the rear win-
dows, or all 4 windows at the same
time, otherwise, at high speed, the win-
dows may not close tightly.<
At higher speeds, the ensuing
vacuum in the passenger com-
partment can cause the convertible top
to begin fluttering. Increase the air sup-
ply via the ventilation controls so that a
vacuum does not occur in the vehicle.<
Opening and closing1To close
