takes into account the way in which
way the car has been driven.
Data request: press RANGE key.
A plus symbol (+) in front of the value
indicates that the cruising range is still
being corrected (measuring tolerance).
If three segments flash in the display,
the cruising range is less than 9 miles
(15 km) and the car should be refueled
as soon as possible.
When you refuel, the onboard computer
registers the action only
dif the fuel amount is over 1.2 gallons
(approx. 4 liters).
dthe engine is switched off.
Average fuel consumptionThe computer can calculate average
fuel consumption rates simultaneously
for two distances, e.g., for an entire
journey and for a single section of it.
To start calculations for distance 1:
Key sequence as in illustration.
To start calculations for distance 2:
Repeat key sequence as in illustration.
Data request: press CONSUM key.
Press the key repeatedly to switch
between the average consumption of
the 1st and 2nd section of the journey.
At the same time, the display also indi-
cates which consumption (1 or 2) is cur-
rently indicated.
Distance remaining to destinationDisplays the distance to the destination.
Available only if the total distance was
entered before the start of the journey.
Enter the distance:
Key sequence as in illustration.
Data request: press DIST key.

A special luggage system is available as
an option for your BMW. Please
observe the precautions included with
the installation instructions.
Because roof racks raise the center of
gravity of the car when loaded, they
exercise a major effect on its handling
and steering response.
You should therefore always remember
not to exceed the approved roof weight,
the approved gross vehicle weight or
the axle weights when loading the rack.
For specifications refer to "Technical
data", page 163ff.
Make sure that the load is not too heavy,
and attempt to distribute it evenly.
Always load the heaviest items first (on
the bottom).
Make sure there is sufficient space to
raise the sliding/tilt sunroof.Secure the roof luggage correctly and
securely to prevent it from shifting or
being lost during driving (danger to fol-
lowing traffic).
Drive smoothly: avoid sudden accelera-
tion and braking maneuvers; corner
gently.
The roof load increases the surface
area exposed to the wind: increased
fuel consumption and stress on the roof
are the immediate results.Roof-mounted luggage rack*

Headlamp washer
* and
windshield washer
Capacity approx. 2.65 US quarts
(2.5 liters) for the windshield washer or
5.3 US quarts (5 liters) in conjunction
with the headlamp cleaning system.
Fill with water and - if required - with
antifreeze (according to the manufac-
turer's recommendations).b
We recommend that you mix the
washer fluid before adding it to the res-
ervoir.c
Windshield washer spray
nozzles The spray from the nozzles should be
directed so as to ensure effective
cleaning, even at high speeds.
Use a needle to adjust the nozzles as
required, or have them adjusted by your
BMW Retailer.
Checking oil level As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
Consequently you should check the oil
level regularly with the vehicle posi-
tioned on a level surface - approx. every
600 miles (1,000 km), or more fre-
quently if your vehicle is driven under
increased demands.
To obtain precise readings:
dCheck with engine cold, before start-
ing.
dWhen checking with the engine
warm, wait briefly for the oil to drain
back down into the oil pan (e.g.,
while refueling).
