snow chains BMW Z4 COUPE 2006 E86 Owner's Manual

Technology for driving comfort and safety
50 In the following exceptional circumstances, it
may be effective to activate the DTC for a short
period:
>When driving on snow-covered grades, in
slush or on uncleared, snow-covered roads
>When rocking the vehicle or starting off in
deep snow or on loose surfaces
>When driving with snow chains
Activating DTC
Press the button briefly; the DTC indicator lamp
lights up in the instrument cluster.
Checking
Deactivating DTC
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
Malfunction in the driving stability
control systems
Have the system checked as soon as possible.Drive cautiously, think well ahead and
avoid full brake applications, otherwise
unstable driving conditions could result.<
The vehicle remains operational. Have the sys-
tem checked as soon as possible.
Drive cautiously and think well ahead,
otherwise unstable driving conditions
could result.<
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the handbrake for this.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Depending on vehicle load,
the car may roll backwards a little during this
time span. Drive off without delay after releas-
ing the brake. Otherwise, the drive-off assistant
will no longer hold the car in place after approx.
2 seconds and the car will start to roll back-
wards.< The indicator lamp flashes:
DTC controls the drive forces and
brake forces.
The indicator lamp is lit:
DTC has been activated.
The warning lamp for the brake system
lights up in red, together with the yel-
low indicator lamps for ABS and DSC:
The driving stability control systems
have failed.
Canadian models display these warn-
ing lamps.
The DSC warning lamp lights up
together with the yellow warning lamp
for the brake system:
DSC, including DTC and DBC, are
malfunctioning.
Canadian models display these warn-
ing lamps.

Malfunction
The warning lamp for the brake system
lights up in yellow. The drive-off assis-
tant has failed. The car will not be held
in place after the brake is released. Have the
system checked as soon as possible.
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.
In the event of tire pressure loss, the rolling
radius of the tire changes, thereby affecting the
rotational speed of the wheels. This change is
detected, and a flat tire warning is issued to the
driver.
System requirements
To ensure a reliable flat tire warning, the system
must be initialized with the correct tire inflation
pressures.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
The system could issue a false warning or func-
tion in a delayed manner in the following situa-
tions:
>System was not initialized
>Driving on a snow-covered or slippery road
surface
>Performance-oriented driving: slip at the
drive wheels, high levels of lateral accelera-
tion
>Driving with snow chains attached
Initializing the system
The initialization is completed while you
are driving, and can be interrupted at any
time. Initialization is continued automatically
when you continue driving.
When driving with snow chains, do not initialize
the system.<
1.Start the engine immediately before pulling
away, but do not drive off yet.
2.Press the button until the yellow indicator
lamp in the instrument cluster lights up for a
few seconds.
3.Drive off.
Initialization is completed during the drive,
without any feedback issued.
Flat tire warning
The warning lamp in the instrument
cluster lights up in red. A signal also
sounds. There is a flat tire or a signifi-
cant loss of tire pressure.
1.Cautiously reduce speed to 50 mph/
80 km/h or lower. Avoid strong braking and
steering maneuvers. Do not exceed a maxi-
mum speed of 50 mph/80 km/h.
If the car is not equipped with Run-
Flat Tires, refer to page84, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result after a tire puncture.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If the inflation pressure is correct in all
four tires, it is possible that the Flat
Tire Monitor was not initialized. In this case,
initialize the system.<

approved wheels and tires are used, BMW can-
not evaluate their suitability, and therefore can-
not be held liable for driving safety.<
You can inquire about the correct wheel/tire
combination at your BMW Center.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS and DSC.
To maintain good handling and vehicle
response, only use tires of a single brand and
tread configuration. After a tire has been dam-
aged, for instance, mount the original wheel and
tire combination again as soon as possible.
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Run-Flat Tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, moreover, no spare wheel is
available. Your BMW Center will be glad to pro-
vide you with more information.
For safety reasons, BMW recommends
that damaged Run-Flat Tires be replaced
rather than repaired.<
Special characteristics of winter tires
BMW 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 summer tires, they
generally do not achieve the full performance of
winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW Center
can supply these labels.
Storage
Store tires in a cool, dry place, protecting them
against light whenever possible. Protect the
tires from contact with oil, grease and fuel. Do
not exceed the maximum tire inflation pressure
indicated on the sidewall of the tire.
Snow chains*
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW Center for
more information. Attach snow chains in pairs
and only to the rear wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h when using snow chains.
You are not permitted to mount snow chains to
tires of the following sizes:
>255/40 R 17
>255/35 R 18
Do not initialize the Flat Tire Monitor if
snow chains are mounted, otherwise the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DTC temporarily, refer to
page50.<
