Fuel gauge Temperature gauge Service Interval Display Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
Fuel tank capacity:
approx. 16.6 gal. (63 liters).
If the tilt of the vehicle varies (when you
are driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds. RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on while operating
the vehicle, the engine has overheated.
Switch off the engine immediately and
allow it to cool down.
Checking coolant level: refer to
page 118.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector in normal operation.
Remaining distance for serviceThe 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 OILSERVICE or INSPECTION,
together with the distance remaining
before the next scheduled service.
The computer bases its calculations of
the remaining distance on the
preceding driving style.
A flashing message and a "Ð" 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.

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.
To avoid the possibility of damage later
on, never use anything other than
factory-approved, nitrite and amino-
free extended-duty antifreeze with
corrosion inhibitor. Your BMW center is
familiar with the official specifications.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their original
containers and in a location inacces-
sible to children. Extended-duty anti-
freeze with corrosion inhibitor contains
ethylene glycol, a flammable
substance. For this reason, do not spill
extended-duty antifreeze with corrosion
inhibitor on hot engine parts. It could
catch fire and cause burns.<
Check the coolant level and
add coolant

Check the coolant level when the
engine is cold (approx. 68 7 or
+20 6).
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 is at least
even with the upper edge of the filler
neck (refer to the arrow in the illustra-
tion), but no more than 0.8 in (2 cm)
above it Ð that is, up to the second
mark on the float (refer also to the
schematic diagram next to the filler
neck)
3. If necessary, add coolant. If the
coolant is low, slowly add
coolant until the correct level is
reached Ñ do not overfill.
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
