minimum. Top up the brake fluid at
the earliest opportunity. Refer to
page 118. Have the source of the
brake fluid loss diagnosed and cor-
rected at your BMW center
>"TIRE DEFECT"

Reduce vehicle speed immediately
and stop the vehicle. Avoid hard
brake applications. Do not oversteer.
Refer to page 83

imum, so add engine oil as soon as
possible. Refer to page 115. Until
then, do not drive more than approx.
30 miles (50 km)>"TIRE PRESSURE SET"
The Flat Tire Monitor has adopted the
tires' current inflation pressures as its
reference levels. Refer to page 82

Transient malfunctions and system
errors in the Flat Tire Monitor. Refer
to page 83

OverviewControlsMaintenanceRepairsDataIndex
Engine oil CoolantSpecified engine oils The quality of the engine oil is
extremely important for the function
and service life of an engine. Based on
extensive testing, BMW approves only
certain grades of engine oil.
Use only approved "BMW High Perfor-
mance Synthetic Oil."
If you are unable to obtain "BMW High
Performance Synthetic Oil," you can
add small amounts of synthetic oil in
between oil changes. Only use oils with
the API SH specification or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
"special oils" which have been
approved.<
You can also call BMW of North
America at 1-800-831-1117 or visit this
website: www.bmwusa.com to obtain
this information.
Viscosity ratings Viscosity is the oil flow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you typically drive your
BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.
Do not add coolant to the cooling
system when the engine is hot.
If you attempt to do so, escaping
coolant can cause scalds. To avoid the
possibility of secondary damage, never
use anything other than factory-
approved, nitrite and amino-free
extended-duty antifreeze with corrosion
inhibitor. Your BMW center is familiar
with these specifications.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their original con-
tainers and in a location which is out of
reach of children. For this reason, do
not spill antifreeze with corrosion inhib-
itor on hot engine parts. It could ignite
and cause burns.<

Coolant Brake fluidChecking coolant level and
adding coolantCorrect coolant level when the engine
is cold (approx. 68 7/20 6):
In the translucent container's visible
range, as far as the graduation marked
KALT/COLD.
1. Turn the cap counterclockwise
slightly in order to allow accumulated
pressure to escape
2. If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.<39mde111
Brake fluid level
The warning lamp for the brake
system hydraulic circuits comes
on and/or the message "CHECK
BRAKE FLUID" appears in the
Check Control:
Brake fluid level too low.
To add brake fluidThe brake fluid reservoir is located
under the microfilter housing on the
driver's side of the vehicle. For adding
brake fluid or for determining and cor-
recting 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).
Brake fluid loss may result in extended
brake pedal travel. If this occurs, refer
to the information on page 108.
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 at
a BMW center. Refer also to the Service
and Warranty Information Booklet (US
models) or the Warranty and Service
Guide Booklet (Canadian models).
Brake fluid is hazardous to health and
damages the vehicle's paint. You
should always store it in its original
container and in a location which is out
of reach of children. Do not spill the
fluid and do not fill the brake fluid reser-
voir 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 dis-
posal of brake fluid.<
