Normal operating range. The needle may
rise as far as the edge of the red sector dur-
ing normal operation.
Red
When you switch on the ignition, warning
lamp 1 comes on briefly to indicate an
operational check.
Comes on while driving:
The engine has overheated. Switch off the
engine immediately and allow it to cool
down.
For checking the coolant level, refer to
page 80.
Service interval display
Remaining distance to next service
The displays shown in the illustration
appear for a few seconds when the ignition
key is in position 1 or after the engine is
started.
The next service due appears with the
message OIL SERVICE or INSPECTION,
together with the distance remaining in
miles – in kilometers in Canada – before the
next scheduled service.
The computer bases its calculations of the
remaining distance on the preceding driv-
ing style.
A flashing message and a "–" in front of the
number mean that the service interval has
already been exceeded by the distance
shown on the display. Please contact your
BMW center for an appointment.
Outside temperature
If the vehicle is not equipped with a com-
puter, the display in the instrument cluster
always shows the outside temperature.
Clock
If you wish to have a permanent time dis-
play, you can have it appear in the car radio
display, refer to the Owner's Manual for
Radio.
You can set the clock and the time display
in the car radio as follows.

onds until the hours are displayed and

Maintenance
The BMW Maintenance
System
The BMW Maintenance System has been
designed as a reliable means of providing
maximum driving and operating safety –
and as cost-effectively for you as possible.
Please keep in mind that regular mainte-
nance is not only necessary for the safety
of your vehicle, but also plays a significant
role in maintaining the resale value of your
vehicle.
Service interval display
While conventional systems rely on dis-
tance traveled alone to determine when a
service is due, the BMW Maintenance Sys-
tem has taken the actual conditions under
which the vehicle is operated into consid-
eration for years, because miles can be
traveled in many different ways:
From a maintenance point of view,
62,000 miles / 100,000 km accumulated in
short-distance urban driving are not the
equivalent of the same distance covered at
moderate speeds in long-distance highway
travel.
The BMW Maintenance System includes
the Engine Oil Service and Inspections I
and II.
Determining the maintenance intervals
based on the actual loads on the vehicle
covers every kind of operating situation.
Minimal use drivers, who drive fewer than
6,200 miles / 10,000 km per year, should
nevertheless have the oil changed at least every 2 years since engine oil deteriorates
over time, regardless of use.
Service and Warranty Information
Booklet for US models/Warranty and
Service Guide Booklet for Canadian
models
For detailed information on required main-
tenance items and the work involved,
please refer to the Service and Warranty
Information Booklet for US models or to the
Warranty and Service Guide Booklet for
Canadian models.
Depending on operating conditions, it may
be advisable to have the body checked for
damage from rocks or gravel as a precau-
tion against corrosion.
BMW recommends that you have your
BMW center perform the mainte-
nance and repair.
Check that the maintenance work is
recorded in the Service Manual. These
entries will serve as proof that the vehicle
has received regular maintenance.<
