systems
In contrast to the descriptions in the Owner's
Manual for the BMW Z4, your BMW Z4 M Road-
ster/Z4 M Coupe does not feature Dynamic
Traction Control DTC.
Dynamic Stability Control DSC
DSC prevents slip at the drive wheels while
starting off and accelerating the vehicle. DSC
also recognizes unstable vehicle conditions,
such as fishtailing or nose-diving. In these
cases, and subject to physical limits, DSC helps
to keep the vehicle on a steady course by
reducing engine speed and by applying brakes
at individual wheels.
The laws of physics cannot be repealed
even with DSC. It will always be the
driver's responsibility to drive in a manner that
matches road conditions. Therefore, do not
limit the additional safety margin by practicing
risky driving.<
Deactivating DSC
Press the button; the DSC indicator lamp in the
instrument cluster lights up. No more interven-
tions to increase stability and forward momen-
tum are carried out.
To enhance vehicle stability, reactivate DSC as
soon as possible.
Activating DSC
Press the button briefly; the indicator lamp goes
out in the instrument cluster.
Checking
The indicator lamp flashes:
DSC controls the drive forces and
brake forces.
The indicator lamp is lit:
DSC is deactivated.
Flat Tire Monitor FTM
In contrast to the descriptions in the Owner's
Manual for the BMW Z4, your BMW Z4 M Road-
ster/Z4 M Coupe is not equipped with Run Flat
tires. You should therefore observe the follow-
ing when you receive a flat tire warning.
Flat tire warning
The warning lamp in the instrument
cluster lights up in red. A signal also
sounds. There is a flat tire or substantial
loss of tire pressure.
1.Reduce speed and pull the vehicle over
carefully. Avoid strong braking and steering
maneuvers.
2.Determine which tire is damaged. To do
this, check the tire inflation pressure using
the M Mobility System, refer to Restoring
tire inflation pressure on page33.
3.Use the M Mobility System to repair the flat
tire, refer to page31.
Power steering
In contrast to the descriptions in the Owner's
Manual for the BMW Z4, your BMW Z4 M Road-
ster/Z4 M Coupe is equipped with hydraulic
power steering.

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 deactivate DSC temporarily, refer to
page18.<
