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. 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.<
Refueling

85
Fuel gaugeOnce the indicator lamp stays on con-
tinuously, there are still approx. 2.1 gal-
lons/8 liters of fuel in the fuel tank.
Fuel tank capacity approx.
16.6 gallons/63 liters.
Certain operating conditions, such as
those encountered in mountainous
areas, may cause the needle to fluctu-
ate slightly.
Fill the fuel tank before it is com-
pletely empty. Driving to the last
drop of fuel can prevent the engine
from operating properly and result in
damage.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
Engine coolant temperature gaugeBlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector during normal operation.RedWhen you switch on the ignition, the
warning lamp comes on briefly as an
operation check.
If the lamp comes on during normal
vehicle operation: the engine has over-
heated. Shut off the engine immediately
and allow it to cool down.
To check coolant level, refer to
page 144.

Service interval displayRemaining distance to next
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or higher or
after the engine is started.
The next service due appears with the
message OIL SERVICE or
INSPECTION, together with the dis-
tance remaining in miles – in kilometers
in Canada – before the next scheduled
service.
The computer bases its calculations of
the remaining distance on the preced-
ing driving style.
A flashing message and a "–" in front of
the number mean that the service inter-
val has already been exceeded by the
distance shown on the display. Please
contact your BMW center for an
appointment.
Check ControlDisplayWhen the ignition key is in position 2,
the following information and/or condi-
tions are indicated using symbols until
the conditions have been corrected.
1Check the low and high beams as
well as the parking lamps
2Door open
3Luggage compartment lid open
4Check tail or brake lamps
When you open the driver's door after
having turned the ignition key to posi-
tion 0, you will hear an acoustic signal
for a few seconds to remind you that
the lamps have not been switched off.

Washer fluidHeadlamp* and windshield
washer systemApproximate capacity is
5.6 US quarts/5.3 liters.
Fill with water and, if required, with a
washer antifreeze additive according to
manufacturer's recommendations.
We recommend that you mix the
washer fluid before adding it to
the reservoir.<
Antifreeze agents for the washer
fluid are highly flammable. For this
reason, keep them away from sources
of flame and store them only in closed
original containers, inaccessible to chil-
dren. Comply with the instructions on
the containers.<
Engine oilChecking the oil level1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean
lint-free cloth, paper towel, or similar
material
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts/1 liter. Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.

144
Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.<
Coolant consists of water as well as an
additive such as antifreeze with corro-
sion inhibitor. Not all commercially
available additives are suitable for your
BMW. Your BMW center knows which
additives are appropriate.
Only use approved additives, as
the engine could otherwise be
damaged. The additives are hazardous
to your health; therefore, follow the
instructions on the containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze with corrosion inhib-
itor.<
Checking the coolant level and
adding coolantCheck the coolant level when the
engine is cold, approx. 687/+206.
1. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape, then open
2. The coolant level is correct when the
upper end of the red float rod – see
arrow – is at least even with the
upper edge of the filler neck, is at
least even with the upper edge of the
filler neck; see arrow. The end of the
float may stick out by a maximum of
3/4 in / 2 cm – that is, up to the sec-
ond mark on the float
3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until
the correct level is reached – do not
overfill.
