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.<

The lamps and bulbs are essential fac-
tors contributing to the safety of your
vehicle. Therefore, comply fully with the
following instructions during bulb
replacement. If you are not familiar with
any of the procedures, consult your
BMW center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn in to the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Always switch off all electrical
accessories and systems before
working on them. As an alternative, you
can also disconnect the cable from the
battery's negative terminal. Failure to
observe this precaution can lead to
short circuits.
To prevent injuries and damage,
comply with any instructions provided
by the bulb manufacturer.<

Lamps and bulbs Xenon lamps

The service life of these bulbs is very
long and the probability of a failure is
very low, provided that they are not
switched on and off an unusual number
of times. If one of these bulbs should
nevertheless fail, it is possible to con-
tinue driving with great caution using
the fog lamps, provided traffic laws in
your area do not prohibit this.
Never attempt to perform bulb
changes or any other service oper-
ations on the xenon lamps. Always have
them serviced by professional techni-
cians. The extremely high voltages at
which these lamps operate constitute a
potentially lethal safety hazard.<
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth (this causes scratches). Never
use abrasives or strong solvents to
clean the covers
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with
ample water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<

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

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

Repairing a flat tire5. Make sure that the screw on the rear
of the pressure gauge 3 is tightened
down. Turn on the M Mobility system
(position I, refer to illustration) and
allow 3 minutes to elapse, to let the
sealant flow in. At this point, it is
insignificant what the tire pressure is
6. Turn the device off.
Disconnect the connector hose from
the sealant container and the wheel
valve. Stow the M Mobility system in
the luggage compartment39mde144
7. Right afterward, drive at least
1.2 miles (2 km), so that the liquid
sealant distributes evenly throughout
the inside of the tire. If possible drive
at no less than 15 mph (20 km/h), but
not more than 40 mph (60 km/h).
Stop in a suitable spot
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. Reset the tire pressure to 29 psi
(200 kilopascal), and:
>Increase the tire pressure: turn on
the M Mobility system (position I).
To check the new tire pressure
briefly turn off the device
>Reducing tire pressure: turn the
screw on the back of the pressure
gauge, a valve located there will
open
