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.<

Technical modifications California Proposition 65 WarningLight-emitting diodes (LEDs)Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and dis-
plays in your vehicle. The concept
behind their operation is related to that
employed for lasers.
Do not remove the protective lens
and avoid staring directly at the
unfiltered beam for extended periods
(several hours), as inflammation of the
iris could result.<
California laws require us to state the
following warning:
Engine exhaust, some of its con-
stituents, and certain vehicle com-
ponents contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, certain
fluids contained in vehicles and certain
products of component wear contain or
emit chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash your hands after
handling.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by
washing thoroughly with soap and
water.<

OBD interface socketThe Onboard Diagnostic (OBD) inter-
face socket is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover. The
cover has the letters "OBD" on it.
The purpose of the OBD (Onboard-
Diagnostics) system is to assure proper
emission-control system operation for
the vehicle's lifetime by monitoring
emissions-related components and
systems to detect deterioration and
malfunction.390us739
An illuminated indicator informs
you of the need for service, not
of the need to stop the vehicle.
However, the systems should be
checked by your BMW center at the
earliest possible opportunity.
Under certain conditions, the indicator
will blink or flash. This indicates a rather
severe level of engine misfire. When
this occurs, you should reduce the
speed and consult the nearest BMW
center as soon as possible. Severe
engine misfire over only a short period
of time can seriously damage emis-
sions-control components, especially
the catalytic converter.
Service Engine Soon warning
lamp for Canadian models.
When the fuel filler cap is not
properly tightened, the OBD
system can detect the vapor leak and
the indicator will light up. If the filler cap
is subsequently tightened, the indi-
cator should go out within a few days.<

Repairing a flat tire
Precautions in case of a flat tire:
Stop the vehicle as far as possible
from passing traffic. Switch on the
hazard warning flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse and engage the parking
brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area (behind a guardrail,
for instance).
If necessary, set up your warning tri-
angle or portable hazard warning lamp
on the roadside at an appropriate dis-
tance from the rear of the vehicle.
Comply with all safety guidelines and
regulations.<
M Mobility systemFor repairing a flat tire, you will find an
M Mobility system in the BMW M5. With
the aid of this system, you can apply a
liquid sealant to the inside of the tire,
thereby sealing off the damaged area,
and then continue driving.
The M Mobility system makes the trans-
port of a spare wheel superfluous and
minimizes the curb weight.
The M Mobility system is located in the
luggage compartment under the floor
mat:
1. Lift up the floor mat and then raise
the front cover panel
2. Loosen the M Mobility system from
its storage location.
Please note that the system's
sealant container must be
replaced every three years by your
BMW center if the device is not used.<39mde132

system1 On/Off switch

Repairing a flat tireUse the M Mobility system
If possible, leave the foreign
object in the tire.<
Do not exceed the maximum
speeds indicated below, as an
accident could result.
Before you use the M Mobility system,
read the warnings and danger notices
on the device carefully.<
1. Remove the warning sticker 5 for
maximum speed that is located on
top of the device and affix it to the
steering wheel
2. Take off the round cover and extract
hose 4. Unscrew the valve stem cap
from the defective tire, then screw
the hose onto the valve stem. Avoid
losing the valve stem cap39mde142
3. Flip open the cover and pull out the
enclosed protective gloves. Take out
hose 2 with the pressure gauge and
screw it to the connection on the
sealant container, as shown in the
illustration
4. Make sure that the system has been
switched off (position 0). Take out
plug 6 and plug it into the cigarette
lighter socket in the passenger com-
partment (refer to page 98)39mde143
