ing normal operation.

When you switch on the ignition, warning
lamp 1 comes on briefly to indicate an
operational check.

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.

If the vehicle is not equipped with a com-
puter, the display in the instrument cluster
always shows the outside temperature.

Washer fluids for washer
systems
Headlamp* and windshield washer
system
Capacity of windshield washer system:
approx. 3.2 US quarts / 3 liters.
Capacity when equipped with headlamp
washer system: approx. 5.3 US quarts /
5 liters.
Fill with water and – if required – with an
antifreeze agent according to the manufac-
turer's recommendations.
We recommend that you mix the
washer fluid before adding it to the
reservoir.<
Antifreeze agent for the washer sys-
tems is flammable. For this reason,
keep it away from sources of flame and
store it only in its original container. Store it
so that it is inaccessible to children. Com-
ply with the instructions on the contain-
ers.<
Engine oil
Engine oil pressure
The red engine oil warning lamp
lights up:
Stop the vehicle immediately and
switch off the engine. Check the engine oil
level and top off as required. If the oil level
is correct, please contact the nearest BMW
center.
Do not continue driving, as the engine
could sustain serious damage from
inadequate lubrication.<
Engine oil level
The yellow engine oil indicator lamp
lights up while driving:
The oil level is at the absolute mini-
mum; refill as soon as possible. Do not
drive more than approx. 30 miles / 50 km
until you do.
The yellow engine oil indicator lamp
lights up after the engine is
switched off: add engine oil at the
earliest opportunity, when you stop to
refuel.
Engine oil sensor
The yellow engine oil indicator lamp
lights up within 20 seconds after
the engine is started:
The oil level sensor is defective. Please
have it checked by a BMW center.
Checking the oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature
3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
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
6.Return the dipstick to the guide tube,
inserting it as far as it will go.
As with fuel economy, oil consumption is
directly influenced by your driving style and
vehicle operating conditions.
