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.
Deactivate the Tire Pressure
Warning system (RDW) when
using snow chains. Malfunction warn-
ings and undetected losses in pressure
are a possibility when driving with snow
chains.
For further information, refer to
page 81.<
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 to ensure
continued safety.
Inflate tires to specified pressure and
have the wheels balanced every time
the tires or wheels have been rotated;
re-initialize the Tire Pressure Warning
system (RDW) as well. Refer to page 81

for further information.
Special features of winter tires Snow chains
*
Choosing the right tireBMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. So-called all-season
tires with the M+S identification mark
do indeed possess better winter trac-
tion than summer tires that have the H,
V, W, Y and ZR speed ratings, but they
generally fail to provide the same levels
of performance as winter tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer with
the same tread configuration on all four
wheels. Do not exceed specified
maximum speeds
Never exceed the maximum
speed for which the tires are
rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.

professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<

Engine oil manual transmission, the differential,
and the power steering system.<
Recommendation: have the oil changed
by your BMW center only.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, thoroughly
wash any areas of skin that come into
contact with oil using soap and water.
Always store oils, grease and similar
materials so that they are inaccessible
to children. Comply with warning labels
and information on containers.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of used oil. mely important for the function and life
of an engine. Based on extensive
testing, BMW approves only certain
types of engine oil.
Use only approved "BMW High Perfor-
mance Synthetic Oil."
If you are unable to obtain "BMW High
Performance Synthetic Oil," you may
use small volumes of other approved
synthetic oils for topping up between oil
changes. Use only oils with the specifi-
cation API SH or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
synthetic oils that have been
approved.<
You can also call BMW of North
America at 1-800-831-1117 or visit this
website: www.bmwusa.com to obtain
this information.Viscosity ratings Viscosity is the oil flow rating as defined
in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These kinds of oil may be used for
driving in all ambient temperatures.

Important safety notices
Do not attempt to remove the gas
generators of the airbag supple-
mental restraint system from the
vehicle. Have testing and service
procedures performed by specially-
qualified technicians only. In the event
of a malfunction, deactivation, or trig-
gered actuation (as a response to an
accident) of the airbag restraint system,
consult your BMW center for repairs or
service operations.
No modifications may be made on
either the wiring or to individual compo-
nents. This also includes the uphol-
stered covers on the steering wheel, on
the instrument panel, in the door side
trim panels or in the rear. Never apply
adhesive materials to these compo-
nents or cover or modify them in any
way. Do not attempt to remove or
dismantle the steering wheel.
To ensure compliance with official
safety regulations, entrust disposal of
airbag generators to a BMW center.
Unprofessional attempts to service the
system could lead to failure in an emer-
gency or undesired airbag activation,
either of which could result in personal
injury.<

Repairing a flat tire
Precautions in case of a flat tire:
Stop the vehicle as far as possible
from passing traffic; turn on the hazard
warning flashers.
Turn the steering wheel to the straight-
ahead position and engage the steering
lock. Engage the parking brake and
shift into 1st or reverse.
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 regula-
tions.<
M Mobility systemAn M Mobility system for fixing flat tires
is included with your BMW M3 convert-
ible. 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 Raise the floor panel (refer to
page 41).
2 Loosen the M Mobility system from
its storage location.
Note that the fluid bottle in the
system's sealant container has to
be replaced every three years by your
BMW center, if the system is not
used.<

Use the M Mobility system
If possible, leave the foreign
object in the tire.<
Do not exceed the maximum
speed limits described below,
otherwise it could lead to accidents.
Before you use the M Mobility system,
read the warnings and danger notices
on the device carefully.<
1 Pull sticker 5 off for maximum speed
and affix it to the steering wheel.
2 Take the round cover off and hose 4
out. Unscrew the valve stem cover
from the defective wheel and screw
the hose to the valve.

Dynamic Stability Control (DSC) Safety belt tensioner

Highly sensitive sensors monitor the
number of revolutions of the wheels,
steering angle, lateral acceleration,
brake pressure and the movement of
the vehicle around its vertical axis.
If differences in wheel speed should
occur, the system will recognize the
potential dangers associated with
wheel spin and will reduce the drive
torque; if necessary, it will do so using
brake intervention at the rear wheels as
well.
When instable vehicle operating condi-
tions are detected, the application of
the brakes with DSC can also act on the
front wheels to stabilize the vehicle.
You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
drive force and vehicle stability.
The braking intervention may be
accompanied by a certain degree of
noise.The safety belt tensioner makes sure
that the belt tightens during a head-on
collision to ensure that occupants
remain firmly positioned in their seats.
A gas-pressure system retracts the
buckle assembly to tension the
shoulder and lap belts within fractions
of a second. This tends to reduce the
tendency to slide under the lap belt
even more.
