Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
by
+ are tested for proper functioning whenever
the ignition key is turned. They each light up
once for different periods of time.
If a malfunction occurs in one of the monitored
systems, the corresponding lamp does not go
out after the engine has started, or it lights up
again while the vehicle is in motion. More infor-
mation can be found on the specified pages or
in the Owner's Manual for the BMW Z4 under
the respective terms.
Colors
The indicator and warning lamps can light up in
various colors and combinations.
>Red:
Stop the vehicle immediately
or

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The laws of physics cannot be repealed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.

Special operating instructions
Break-in procedures
In contrast to the descriptions in the Owner's
Manual for the BMW Z4, please take note of the
following differences for your BMW Z4 M Road-
ster/Z4 M Coupe.
Always obey all official speed limits.
Engine and differential
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed 5,500 rpm or 100 mph/170 km/h.
Strictly avoid depressing the accelerator pedal
to full-throttle position.
After the breaking-in inspection at 1,200 miles/
2,000 km, engine or road speeds can be gradu-
ally increased.
Transmission
The function of the transmission reaches its
optimal level only after driving a distance of
approx. 300 miles/500 km. Do not exceed
engine speeds of 5,500 rpm during this time.
After replacing components
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Driving notes
Ground clearance
The front spoiler greatly restricts the
vehicle's ground clearance. Make sure
that your BMW always has sufficient ground
clearance, e.g. when entering underground
garage complexes or driving over the edge of a
curb; otherwise the front spoiler could be dam-
aged.<
Braking safely
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 perforated
brake discs.
In certain braking situations, operation of the
perforated brake discs can cause noise; how-
ever, this does not affect the performance and
operating safety of the brakes.

Engine oil
Like fuel consumption, engine oil consumption
depends on your driving style and the vehicle's
operating conditions.
Warning lamp
Engine oil pressure
The warning lamp lights up in red:
The engine oil pressure is too low.
Stop the vehicle immediately and
switch off the engine. Check the engine oil level
and top up if necessary. If the oil level is correct,
please contact your nearest BMW Center or a
workshop that works according to BMW repair procedures with correspondingly trained per-
sonnel.
Do not continue driving, otherwise the
engine could sustain serious damage
from inadequate lubrication.<
Engine oil level
The warning lamp lights up in yellow
while you are driving. A signal also
sounds.
The oil level is at the absolute minimum; check
engine oil level using dipstick 7 and refill as
soon as possible. Do not drive more than
30 miles/50 km before refilling.

Onboard tool kit
The onboard tool kit is stored in a tool pouch.
Roadster
The onboard tool kit can be found on the right-
hand side of the cargo bay in a compartment
next to the battery cover.
Coupe: access to onboard tool kit
1.Turn the quick-release fastener counter-
clockwise.
2.Pull out the cover.
When reinstalling the cover, make sure
that its tabs are inserted into the corre-
sponding cut-outs in the cargo bay trim panel. hand side of the cargo bay on top of the battery.
M Mobility System
Repairing a flat tire
To repair a flat tire, an M Mobility System is pro-
vided in your BMW Z4 M Roadster/Z4 M Coupe.
Using this system you can apply a sealant to the
inside of the tire, seal off the damaged area,
restore the tire inflation pressure and then con-
tinue driving.
Safety measures in the event of a flat:
Park the vehicle as far as possible from
passing traffic and on solid ground. Switch on
the hazard warning flashers.
Lock the steering wheel so that the wheels are
facing straight ahead. Apply the handbrake and
engage first or reverse gear. Have all vehicle
occupants get out of the vehicle and ensure
that they remain outside the immediate area in a
safe place, such as behind a guardrail.
If a warning triangle or portable hazard warning
lamp is required, set it up on the roadside at an
appropriate distance from the rear of the vehi-
cle. Comply with all national safety guidelines
and regulations.<
Preparation
If possible, do not remove foreign bodies which
have penetrated the tire.
