Fuel gaugeOnce the indicator lamp stays on con-
tinuously, 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.
Fill the fuel tank before it is com-
pletely empty. Driving to the last
drop of fuel can prevent the engine
from operating properly and result in
damage.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
Engine coolant temperature gaugeBlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector during normal operation.RedWhen you switch on the ignition, the
warning lamp comes on briefly as an
operation check.
If the lamp comes on while operating
the vehicle: the engine has overheated.
Switch off the engine immediately and
allow it to cool down.
To check the coolant level, refer to
page 128.

However, if the vehicle is exposed to
temperatures below –47/–206 for
extended periods, please have your
BMW center recommend a suitable oil.
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.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their closed origi-
nal containers and in a location inac-
cessible to children. Antifreeze and
anti-corrosion agents are inflammable.
For this reason, do not spill them on hot
engine parts. They could ignite and
cause burns. Comply with the instruc-
tions on the containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze agents with corro-
sion inhibitor.<
Checking coolant level and
adding coolant Check the coolant level when the
engine is cold, approx. 687/+206.
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 illus-
tration – but no more than 3/4 in /
2 cm above it – that is, up to the sec-
ond mark on the float. Refer also to
the schematic diagram next to the
filler neck

3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until
the correct level is reached — do not
overfill.
Brake fluidIndicator lamp
The brake warning lamp comes
on when the parking brake is
not engaged: brake fluid level
too low, refer to page 18.
Brake warning lamp for Cana-
dian models.
Adding brake fluidFor adding brake fluid or for determin-
ing and correcting the cause of brake
fluid loss, consult your BMW center.
Your BMW center is familiar with the
specifications for factory-approved
brake fluids – DOT 4.
Due to loss in brake fluid, pedal travel
can lengthen and braking efficiency
may be reduced. Refer to the informa-
tion on page 114.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW center. Refer also to the Service
and Warranty Information Booklet for
US models or the Warranty and Service
Guide Booklet for Canadian models.
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its closed original container and in
a location inaccessible to children.
Do not spill the brake fluid and do not
fill the brake fluid reservoir beyond the
MAX mark. The brake fluid could ignite
upon contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of brake fluid.<
