Tachometer Energy control Fuel gaugeNever allow the engine to operate with
the needle in the red overspeed zone of
the gauge.
To protect the engine, the engine-man-
agement system automatically inter-
rupts the fuel supply in this range; the
resulting effect resembles that associ-
ated with a sudden loss of power.390us004
Indicates current fuel consumption in
mpg (in liters per 100 km on Canadian
vehicles). This instrument shows
whether your current driving style is
conducive to fuel economy with mini-
mum exhaust emissions.
When the vehicle is stationary, the dis-
play goes to "Maximum" (zero on Cana-
dian models).390us005
When you switch on the ignition, the in-
dicator lamp comes on briefly to con-
firm that the system is operational.
If the indicator lamp stays on, there are
approx. >2.0
gal (8 liters) –
BMW 525i, BMW 530i
>2.5 gal (10 liters) – BMW 540i
remaining in the tank.
Tank capacity: refer to page 223.
Certain operating conditions (such
as those encountered in mountainous
areas) may cause the needle to fluctu-
ate slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.< 390us006

ComputerMode selectionFrom ignition key position 1 and up, you
can call up information from the com-
puter using the button in the turn signal
lever. By pressing the button briefly in
the direction of the steering column,
you can call up a new function for dis-
play.
The displays appear in the following
order: outside temperature, average
fuel consumption, cruising range, aver-
age speed.
Starting with ignition key position 1, the
last active setting is displayed.
The range of available displays varies
according to your individual vehicle's
equipment.390de336
Outside temperature and
average fuel consumptionYou can change the units of measure
(7/6) for the outside temperature dis-
play by
1 pressing and holding the trip odome-
ter reset button (in ignition key posi-
tion 1)
2 and then turning the ignition key to 0.
Refer also to page 83.390us126
Cruising range and
average speed The computer bases its calculations
of the cruising range on the previous
driving style and conditions.
The computer ignores any time spent
with the vehicle stationary and the
engine off in its average speed calcula-
tions.390us703

Multi-Information Display (MID)
*
Central displayThe MID serves as the central display
and operation for the following onboard
systems:
>Digital clock (e. g. time display, date)
>Audio systems (radio, cassette, CD)
>Computer ( e.g. fuel consumption,
cruising range)
>Cellular phone ( e.g. dialing)
You will find explanations and notes
for operating the digital clock and the
computer on the following pages.
Please refer to the separate Owner's
Manual for operating the audio
systems, the cellular phone and the
onboard monitor.
Any unrealistic numerical entries
will not be accepted.
All stored data will be lost if the power
supply is interrupted. Time display,
switch-on times for independent
heating and ventilation, distance and
cruise control speed limit may have to
be reset once the power supply has
been re-established.<

Estimated time of arrivalWhen you have input the distance from
your destination, you can obtain an
estimated time of arrival display which
is continuously updated by the com-
puter as your average driving period
varies.
Press the right of the button.
Press on the right:
The estimated time of arrival is
displayed.
Cruising rangeThe distance which the vehicle should
cover on the remaining fuel in the tank
is displayed.
Press the right of the button.
Press.
The display shows the probable range.
When you have only enough fuel
left to drive fewer than 30 miles
(50 km), then refuel, as otherwise the
engine or the catalytic converter could
be damaged.<
The computer will only register fuel
amounts over 1.8 gal (6 liter).
Fuel consumptionYou can have the average fuel
consumption displayed for two different
distances, for example a complete
journey and part of the journey .
To start the calculation, select the
CONS function with the engine running.
Press the right side of the button.
Press on the left or right:
The display will show the average fuel
consumption.
To restart the fuel consumption
calculation:
Press on the left or right.
Press the right side of the button.

137nRoof-mounted luggage rack
Mounting points
Access to the mounting points:
To fold up the cover (arrow), please use
the tool which is provided with the lug-
gage system.
A special luggage system is available
as an option for your BMW. Please
comply with the precautions included
with the installation instructions.
Because roof racks raise the center of
gravity of the car when loaded, they ex-
ercise a major effect on its handling and
steering response.
394de369
You should therefore always remember
not to exceed the approved roof
weight, the approved gross vehicle
weight or the axle weights when load-
ing the rack. You will find the specifica-
tions under "Technical data" on
page 221.
Make sure that the load is not too bulky,
and attempt to distribute it evenly.
Always load the heaviest pieces first (on
the bottom). Be sure that adequate
clearance is maintained for raising the
sliding/tilt sunroof, and that objects do
not project into the opening path of the
luggage compartment lid/tailgate.
Secure the roof luggage correctly and
tightly to prevent it from shifting or be-
ing lost during driving (danger to follow-
ing traffic).
Drive smoothly. Avoid sudden accelera-
tion and braking maneuvers. Take cor-
ners gently.
The roof load increases aerodynamic
resistance: increased fuel consumption
and stress on the roof are the immedi-
ate results.

Overview
165nEngine oil
Checking oil level
1 Park the vehicle on a level surface.
2 Shut the engine off after it has
reached normal operating
temperature.
3 After approx. 5 minutes, pull the dipstick 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 in between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
390de647
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.
460de189
To add oil
Wait until the level has dropped to just
above the lower mark before adding oil.
However, do not wait until the oil level
drops below the lower mark.
BMW engines are designed to op-
erate without oil additives; the use
of additives could lead to damage in
some cases. This is also true for the
manual transmission, the automatic
transmission, the differential, and the
power steering system. <
