Special characteristics of winter tires Snow chainsChoosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under adverse
winter driving conditions. So-called all-
season tires with the M+S identification
mark do indeed possess better winter
traction than summer tires that have the
H, V, W, Y and ZR speed ratings, they
generally fail to provide the same levels
of performance as snow tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer having
the same tread configuration on all four
wheels. Do not exceed specified
maximum speeds
Never exceed the maximum
speed for which 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. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureOnce winter tires wear to a tread depth
of less than 0.16 in (4 mm), their perfor-
mance under winter driving conditions
deteriorates noticeably. Worn tires
should therefore be replaced for safety
considerations.
Inflate tires to specified pressure and
have the wheels balanced every time
the tires or wheels have been replaced.Use narrow-link BMW snow chains
* on
winter tires in pairs only and only on the
rear wheels. Comply with all manufac-
turer's safety precautions when
mounting the chains. Do not exceed a
maximum speed of 30 mph (50 km/h)
with snow chains.
After mounting or removing snow
chains, always reinitialize the sequential
M gearbox
* SMG II, refer to page 65.
It is not possible to mount snow
chains on tires with 18- 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 77.<

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 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 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 systemWith 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. Using the M Mobility systemTo repair a flat tire using the M Mobility
system, proceed as follows:
>Prepare the M Mobility system for
use, refer to the next column
>This is part of the M Mobility system,
refer to page 127
>Filling with sealant, refer to page 127
>Distributing sealant, refer to
page 128
>Inflating tire to correct pressure, refer
to page 129.
Preparing the M Mobility system
for useThe 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.
Before you use the M Mobility
system, read the warnings and
danger notices on the device care-
fully.<
If possible, leave the foreign object in
the tire.
Pull off the sticker 5 (refer to the second
column on the right) for the speed limit
and apply it to the steering wheel.

Repairing a flat tire
Please keep in mind that the fluids
bottle in the system's sealant
container has to be changed every
3 years by your BMW center, if the unit
has not been used.<
This is part of the M Mobility
system1 On/Off switch
2 Connection hose with manometer for
connecting the compressor with the
sealant container or to connect the
compressor to the wheel
3 Manometer 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).
Filling with sealant1. Take the round cover off and hose 4
out. Unscrew the valve stem dust
cap from the defective wheel and
screw the hose to the valve. Keep
the dust cap in a safe place.

128n
Repairing a flat tire2. Flip open the cover and pull on the
enclosed protective gloves. Take out
hose 2 with the manometer and
screw it to the terminal for the
sealant container as shown in the
illustration
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
passenger compartment (refer to
page 93)
4. Make sure that the screw on the rear
of manometer 3 is tightened down.
Turn on the M Mobility system (Posi-
tion 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 sealant 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 1.2 miles
(2 km), so that the liquid sealant distrib-
utes 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 suitable spot.<

Repairing a flat tire Inflating tire to correct pressure1. Take the hose with the manometer
out and screw it onto the valve.
Take the plug out and plug it into the
cigarette lighter socket in the
passenger compartment
2. Reset the air pressure to 29 psi
(200 kilopascal), and:
>Increase tire pressure: turn on the
M Mobility system (Position I). Turn
the unit off while you check the
current setting for the tire pressure
>Decrease tire pressure: turn the
screw on the back of the mano-
meter, 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
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. 0.16 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,
otherwise it could lead to accidents.<
After the flat tire has been fixed and you
start driving again, do not exceed a
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
balanced. Reinitialize the Flat Tire
Monitor, and refer to page 78 for further
information. 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.

Towing the vehicleTowing a vehicle1. Shift lever in Neutral
2. Towing speed:
Max. 45 mph (70 km/h)
3. Towing distance:
Max. 95 miles (150 km)
4. Leave the ignition key at position 1 to
ensure that the brake lamps, turn
signal indicators, horn and wind-
shield wipers remain operative, and
to prevent the steering lock detent
from engaging
5. Switch on the hazard-warning
system (observe applicable legal
regulations).
Find some means of identifying the
vehicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed to
prevent the steering lock from
engaging.
The steering and brakes are without
power assist when the engine is off.
This means that increased effort is
required for steering and braking.c
Vehicles with sequential M gearbox
*
SMG II:
To push or tow, engage selector lever
in position 0.
Never work on the vehicle with a
driving position engaged.c
Towing with a commercial tow
truck>Do not tow with sling-type equipment
>Use wheel lift or flatbed equipment
>Please comply with applicable state
towing laws.
Never allow passengers to ride in
a towed vehicle for any reason.
Never attach tie-down hooks, chains,
straps, or tow hooks to tie rods, control
arms, or any other part of the vehicle
suspension, as severe damage to these
components will occur, leading to
possible accidents.c
