OBD connector The data link connector for onboard
diagnostics is located on the left-hand
side of the driver's side, on the under-
side of the instrument panel and under
a cover panel. The cover is marked with
the letters "OBD".
The purpose of the OBD system is to
assure proper emission control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.
An illuminated indicator informs
you of the need for service, not
that you need to stop the
vehicle. Your system should be
checked, however, at the earliest
possible opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact your
nearest BMW center immediately.
Severe engine misfire over even a short
period of time can seriously damage
emission control system components,
especially the catalytic converter.
"Service Engine Soon" warning
lamp for Canadian models.
If the fuel filler cap is not on tight
enough, the OBD system can
detect leaking vapor and the indicator
will light up. If the fuel filler cap is then
tightened, the indicator will usually go
out after a short period of time.<

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.
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 gear 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 a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle.
Comply with all safety guidelines and
regulations.<
M Mobility system With the BMW M3, you will find an
M Mobility system for fixing flat tires.
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 trans-
porting a spare wheel superfluous,
thereby reducing the amount of weight
you have to carry around.
The M Mobility system is located in the
luggage compartment under the floor
panel:
1 Lift up the floor panel
2 Loosen the M Mobility system from
its storage location.
Note that the fluid bottle in the
system's sealant container must
be replaced every 3 years by your BMW
center if the system is not used.<

system1 On/Off switch
2 Connection hose with pressure
gauge for connecting the compressor
with the sealant container or to
connect the compressor to the wheel
3 Pressure gauge for indicating the tire
pressure
4 Connector hose from the sealant
container to the wheel
5 Sticker for maximum speed
6 Plug and cable for the cigarette
lighter socket
7 Protective gloves (not shown).
Use the M Mobility system
If possible, leave the foreign
object in the tire.<
Do not exceed the maximum
speed limits described below,
otherwise accidents could result.
Before you use the M Mobility system,
read the warnings and danger notices
on the device carefully.<
1 Pull sticker 5 off for speed limit and
affix it to the steering wheel
2 Remove the round cover and take out
hose 4. Unscrew the valve stem
cover from the defective wheel and
screw the hose to the valve
148n
Repairing a flat tire Battery 8 Take out the hose with the pressure
gauge and screw it onto the valve.
Take out the plug and plug it into the
cigarette lighter socket in the
passenger compartment
9 Inflate the tire pressure:
>To increase the tire pressure: turn
on the M Mobility system
(position I). To check the new tire
pressure briefly turn off the device
>To reduce the tire pressure: turn
the screw on the back of the pres-
sure gauge; this will open the air
release valve
If the air pressure won't hold, still
carry out step 10 and then repeat
steps 7 through 10 again.
The use of the M Mobility system may
be ineffective if the damaged area in
the tire is larger than approx. 0.16 in
(4 mm). Please consult the nearest
BMW center if the tire cannot be
temporarily repaired with the M Mobility
system.<
10 Unscrew the hose from the valve
and stow the M Mobility system in
the luggage compartment.
After the flat tire has been fixed and you
start driving again, do not exceed a
maximum speed of 50 mph (80 km/h).
You will find corresponding instructions
for using the M Mobility system on the
device.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced. Re-initialize the Tire Pressure
Warning system (RDW), refer to
page 78 for further information. Have
the M Mobility system refilled. Contact
your BMW center for this.
Battery locationThe battery is located at the right-rear
of the luggage compartment. Raise the
luggage compartment floor panel (refer
to page 39). Using a screwdriver or a
coin and f turn, release both of the
caps as shown in the illustration, taking
them out along with an additional cap in
the top center of the right side trim
panel. Remove the fasteners. In order
to remove the storage tray, slide the
side trim panel slightly upward.
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<

Self-diagnostics All of the important electrical and elec-
tronic systems in the vehicle are tested
regularly and automatically Ð the driver
does not have to perform any extra
operations or adjustments.
The indicator lamps also come on
briefly after the ignition has been turned
on.
In the same manner, the electrical
resistance of the airbag ignition genera-
tors and all of the remaining airbag
components are constantly being
measured. Any fault in this system
would be detected immediately by a
current fluctuation that would neces-
sarily accompany it. The fault would be
indicated immediately by the airbag
warning lamp.
Even after you shut off the engine, the
overall functional status of your vehicle
is monitored. For example, all of the
flaps of the heating and ventilation
system travel to the nearest limit posi-
tion. This action ensures that the
defrost function will be preserved,
regardless of the circumstances, even
if, for example, a malfunction in the
heating or ventilation system should
occur during the night while the vehicle
is parked.
A calibration cycle runs every tenth time
the engine is shut off. During this cycle,
the actuator motors of all the heating
and ventilation flaps travel to their limit
stops in both directions. The limit posi-
tions and the return travel paths are
checked in this manner in order to
ensure that appropriate adjustments for
the operating elements can be made at
any time.
You can hear the vent flaps of the
heating or ventilation system
performing their self-diagnostics
routine after turning off the ignition. All
of the other self-diagnostics functions
operate silently in the background.Any possible faults detected during
these self-diagnostics can be read out
and corrected by your BMW center
during the next regularly scheduled
maintenance.
