malfunction on Canadian models.
For your own safety: use only brake pads
that BMW has approved for your particu-
lar vehicle model. As BMW cannot assess the
suitability of other brake pads for use on your
vehicle, BMW is unable to assume continued
responsibility for the vehicle's operating safety
if non-approved pads are installed.<

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located under a cover on the left
side of the driver's footwell, directly under the
dashboard.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values are deteriorating.
Have the vehicle checked as soon as
possible.
Display of the previously described
malfunction on Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case, you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring causes serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system can detect the
escape of fuel vapor. This causes a display to
light up. If the cap is then tightened, the display
should go out within a few days.<
Event data recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with a
device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to a BMW Assist plan, then certain vehi-
cle data can be transmitted or recorded to
enable corresponding services.
Care
Important information on care and maintenance
of your BMW is contained in the Caring for your
vehicle brochure.

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to driving safety. You must be duly diligent
in replacing them. If you are not familiar with the
specified procedures, have the corresponding
work carried out at your BMW center.Never touch the glass on new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean cloth, napkin, etc., or hold the bulb by its
metal socket.<
A selection of replacement bulbs is available at
your BMW center.
Whenever you perform any work on the
electrical system, turn off the electrical
devices involved to prevent short circuits from
occurring. To avoid possible injury or equip-
ment damage when replacing bulbs, follow any
instructions provided by the bulb manufac-
turer.<
When performing maintenance on the head-
lamps, follow the instructions in the separate
Caring for your vehicle brochure.
For bulbs for which changing is not
described, and for checking and adjusting
headlamp aim, please contact your BMW cen-
ter.<
Light-emitting diodes LEDs
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare into the unfiltered light for several
hours, as irritation of the retina could result.<
Xenon lamps
The service life of these lamps 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.
Have work on the Xenon lighting system
performed only by your BMW center or a
workshop that works according to BMW repair

Stow the M Mobility System in the vehicle
again.
Distributing sealant
Immediately drive approx. 2 miles/3 km so that
sealant is evenly distributed in tire.
Do not exceed a maximum speed of
35 mph/60 km/h. Do not drop below
12 mph/20 km/h if possible.<
Producing tire inflation pressure
1.After approx. 2 miles/3 km, stop at suitable
location.
2.Screw compressor hose9 directly onto tire
valve.
3.Insert connector 3 in lighter socket in vehi-
cle interior.
4.Correct tire inflation pressure to 29 psi/
200 kPa. With the ignition switched on:
>Increase inflation pressure: switch on
device, position I. To check currently set
inflation pressure, briefly switch off
device.
Do not allow compressor to run
longer than 10 minutes, otherwise
the device will overheat and may be dam-
aged.<
>Reduce inflation pressure: press but-
ton8 or turn screw8 on pressure gauge.
If the inflation pressure is not held, drive
the vehicle again, refer to Distributing
sealant. Then repeat steps 1 to 4 once.
Using the M Mobility System can be ineffective
with tire damage from a size of approx. 0.16 in/
4 mm. Please contact the nearest BMW center,
refer to page192, or a workshop that works according to BMW repair procedures with cor-
respondingly trained personnel if the tire can-
not be made ready for driving with the
M Mobility System.<
The tire inflation pressure must be at least
29 psi/200 kPa. Otherwise do not con-
tinue driving.<
Continue driving
Do not exceed the permissible maximum
speed of 50 mph/80 km/h, otherwise
accidents can occur.<
Reinitialize the Flat Tire Monitor.
For details, refer to page74.
Have the defective tire and the sealant bottle of
the M Mobility System replaced as soon as
possible.<
Changing wheels
Safety precautions in the event of a flat
tire or wheel change: park the vehicle as
far as possible from passing traffic and on solid
ground. Switch on the hazard warning flashers.
Lock the steering wheel in straight-ahead set-
ting of the wheels. Set the handbrake and
engage a driving position with the selector
lever.
Have all vehicle occupants get out of the vehicle
and ensure that they remain outside the imme-
diate area in a safe place, such as behind a
guardrail.
If a warning triangle or portable hazard warning
lamp is required, set it up on the roadside at an
appropriate distance from the rear of the vehi-
cle. Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm surface
which is not slippery. The vehicle or the jack
could slip to the side if you attempt to raise the
vehicle on a soft or slippery surface such as
snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar object as a
support base for the jack, as this would prevent
it from extending to its full support height and
reduce its load-carrying capacity.

Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.
3.Position the new wheel or spare wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the
lug bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. The tightening torque is
88.5 lb ft/120 Nm.<
2.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
3.Initialize the Flat Tire Monitor, refer to
page74, and the Sequential Manual Trans-
mission, refer to After changing wheels/
tires on page174.
4.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Stowing wheel and tools
1.Lay the wheel in the tool mounting.
2.Lay the cover on the mounting.
3.Center the wheel and cover relative to the
lashing eyes5.4.Hook the belt into the lashing eyes.
5.Completely open the tensioning lock.
6.Thread the belt3 through the axis6 of the
tensioning lock without twisting it and ten-
sion it by hand.
7.Tighten the belt firmly with the tensioning
lock by opening and closing the lock several
times.
8.Fold the tensioning lock closed and stow
the protruding belt end.
Driving with spare wheel
With certain wheel-and-tire combinations
the size of the spare wheel differs from
that of the other wheels. The spare wheel is
equivalent to them in all load and speed ranges.
However, to restore the original state, the nor-
mal wheel should be remounted as soon as
possible.<
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate.
Your BMW center will be glad to advise in all
matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. For the connections, refer
to Jump starting on page192.

the connection has been established. You will
then be able to provide a detailed description of
the situation.If the current location of your vehicle can be
determined, it will be forwarded to the
BMW Assist response center.
If the LED flashes, but you are unable to hear
the BMW Assist response center through the
handsfree system, this could indicate, for
instance, that the handsfree system is no longer
operational. But the response center is still able
to hear you.
Under certain conditions, an emergency call is
automatically initiated immediately after a
severe accident. The automatic emergency call
is not affected by the button being pressed.
For technical reasons, the emergency call
cannot be guaranteed under the most
unfavorable conditions.<

for tow-starting and towing.<
Do not transport any passengers other
than the driver in a vehicle that is being
towed.<
Using tow fitting
The threaded tow fitting is stored in the tool kit
mounted on the inside of the luggage compart-
ment under the floor mat, refer to page182, and
should always remain in the vehicle. It can be
screwed in at the front or rear of the BMW M6.
Only use the tow fitting that comes with
the vehicle and screw it in as far as possi-
ble. Use the tow fitting for towing only on roads.

Being towed
Make sure that the ignition is switched on,
refer to page50; otherwise, the low-beam
headlights, tail lights, turn signals and wind-
shield wipers would not be available. If the vehi-
cle electrical system fails, do not tow-start or
tow the vehicle. The electric steering-wheel
lock cannot be unlocked and the vehicle cannot
be steered. For information on jump starting,
refer to page192. There is no power assistance
with the engine stopped. This then requires
increased effort for braking and steering.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Engage selector lever position N with the igni-
tion switched on.
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts; otherwise, damage
may result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed; otherwise, it
will not be possible to reliably control vehicle
response. side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please note the following:
>Clearance and maneuvering capability will
be strictly limited during cornering.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Attach the tow bar to the tow fittings only,
as attachment to other vehicle parts can
lead to damage.<
With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach tow ropes to the tow fittings only, as
attachment to other vehicle parts can lead to
damage.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Tow-starting
Do not tow-start the vehicle if possible, but
instead start the engine by means of jump start-
ing, refer to page192. With a catalytic con-
verter, the vehicle should only be tow-started
with the engine cold.
If the electrical system fails, do not tow-
start or tow the vehicle, as otherwise the
electric steering-wheel lock cannot be
unlocked and the vehicle cannot be steered.<
