2004 BMW M3 COUPE flat tire

Winter tiresChoosing the right tireBMW recommends the use of winter
tires for operation under winter road
conditions. While all-season tires – with
M+S designation – provide better winter
traction than the corresponding sum-
mer tires, they generally do not achieve
the performance of winter tires.
In the interest of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
When mounting winter wheels,
observe the different recesses of
the front and rear wheels, as otherwise
damage may result.<
Do not exceed specified
maximum speeds
Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Your BMW center
will be glad to assist you with both their
expertise and the proper equipment for
your vehicle.<
Tire condition, tire pressureAt tread depths below approx. 3/16 in /
4 mm, tire performance under winter
driving conditions deteriorates notice-
ably. Worn tires should therefore be
replaced for safety considerations.
Comply with the specified tire inflation
pressures – and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.
Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult your
BMW center for more information.
BMW recommends using only these
approved fine-link snow chains. Use
them in pairs on winter tires, but only on
both rear wheels.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a maximum speed of
30 mph / 50 km/h when using snow
chains.
After mounting or removing snow
chains, always reinitialize the sequential
M gearbox with Drivelogic, refer to
page 71.
It is not possible to mount snow
chains on tires with 18-inch and
19-inch wheels.
Deactivate the Flat Tire Monitor when
using snow chains. Malfunction warn-
ings and undetected losses in pressure
are a possibility when driving with snow
chains.
For additional information, refer to
page 84.<

Repairing a flat tire
Precautions in case of a flat tire:
Stop the vehicle as far as possible
from passing traffic; switch on the haz-
ard warning flashers.
Turn the steering wheel to the straight-
ahead position 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 trian-
gle or portable hazard warning lamp on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all local safety guidelines and reg-
ulations.
Comply with all safety guidelines and
regulations.<
M Mobility systemYou will find an M Mobility system in the
BMW M3 for repairing flat tires. With
this system you can apply a sealing liq-
uid to the inside of the tire that seals off
the damaged point 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.

Using the M Mobility systemTo repair a flat tire using the M Mobility
system, proceed as follows:
>Preparing the M Mobility system for
use, refer to the next column
>Components of the M Mobility sys-
tem, refer to page 138
>Filling with sealant, refer to page 138
>Distributing sealant, refer to
page 139
>Inflating tire to correct pressure, refer
to page 139.
Preparing the M Mobility system
for useThe M Mobility system is located in the
luggage compartment under the floor
panel:
1. Lift the floor panel
2. Loosen the M Mobility system from
its storage location.
Before you use the M Mobility sys-
tem, read the warnings and dan-
ger notices on the device carefully.<
If possible, leave the foreign object in
the tire.
Pull off the sticker 5, refer to the second
column below, for the speed limit and
apply it to the steering wheel.
Please keep in mind that the fluids
bottle in the system's sealant con-
tainer has to be changed every 3 years
by your BMW center, if the unit has not
been used.<

7Protective gloves, not shown
Filling with sealant1. Take off the round cover and take out
hose 4. Unscrew the valve dust cap
from the defective wheel and screw
the hose to the valve. Keep the dust
cap in a safe place
2. Flip open the cover and pull out the
enclosed protective gloves. Take out
hose 2 with the manometer and
screw it to the terminal for the seal-
ant container as shown in the illustra-
tion
3. Make sure that the system has been
switched off, position 0.
Take out plug 6 and insert it into the
cigarette lighter socket in the pas-
senger compartment – refer to
page 100

4. Make sure that the screw on the rear
of the pressure gauge 3 is tightened
down. Turn on the M Mobility sys-
tem, position I, refer to illustration,
and allow minutes to elapse, to let
the sealant flow in. It does not matter
afterward, what the tire's inflation
pressure is
5. Turn the system off.
Disconnect the connector hose from
the sealant container and the wheel
valve. Stow the M Mobility system in
the luggage compartment.Distributing the sealantRight afterward, drive at least
1 1/4 miles / 2 km, so that the liquid
sealant distributes evenly throughout
the inside of the tire.
Do not exceed a maximum speed
of 40 mph / 60 km/h.
If possible, keep the vehicle speed
above 10 mph / 20 km/h. Stop in a suit-
able spot.<
Inflating tire to correct pressure1. Take out the hose with the pressure
gauge and screw it onto the valve.
Take the plug out and plug it into the
cigarette lighter socket in the pas-
senger compartment
2. Reset the air pressure to 29 psi/
200 kilopascal, and:
>Increase tire pressure: switch on
the M Mobility System, position I.
Switch off the unit briefly to check
the current tire pressure
>Decrease tire pressure: turn the
screw on the back of the manome-
ter. A valve located there will open

Even if the tire fails to hold the
pressure, you should still carry out
Step 3 before proceeding to drive the
vehicle again, refer to Distributing the
sealant for more information. Then
repeat Steps 1 through 3.
The use of the M Mobility system may
be ineffective if the damaged area in
the tire is larger than approx. 1/8 in /
4 mm. Please consult the nearest BMW
center if the tire cannot be temporarily
repaired with the M Mobility system.<
3. Unscrew the hose from the valve and
stow the M Mobility system in the
luggage compartment. Screw the
dust cap onto the valve again.
Do not exceed the maximum
speed limit described below, oth-
erwise it could lead to accidents.<
When you start driving again, do not
exceed the permissible maximum
speed of 45 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 bal-
anced. Reinitialize the Flat Tire Monitor,
and refer to page 85 for further informa-
tion. Have the M Mobility system
refilled. Contact your BMW center for
this.<
Protect valve stems against dirt using
screw-on dust caps. Dirty valve stems
frequently lead to slow pressure loss.
Battery
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
MaintenanceThe battery is completely maintenance-
free. That means that the original bat-
tery acid will normally last for the ser-
vice life of the battery under moderate
climate conditions.
Please consult your BMW center
whenever you have any questions
concerning the battery. when the engine is not running. Use the
connections provided in the engine
compartment. For information on the
connections, see Jump-Starting,
page 143.Disposal
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery against tilting in transit.<
