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The laws of physics cannot be repealed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.

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.
Information for your safety
The factory-approved radial-ply tires are spe-
cifically matched to your vehicle and offer opti-
mal road safety as well as enhanced driving
comfort if used properly.
In the event of a flat tire, proceed as described
under M Mobility System, refer to page31.

Snow chains*
Snow chains may be attached only to winter
tires of the size 225/40R 18 on both rear
wheels.
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.<

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.

32 Corresponding information on using the
M Mobility System is also provided on the
device.<
Before using the M Mobility System, note
the information on the sealant bottle.<
Pull the sticker for the speed limit off the sealant
bottle and affix it to the steering wheel.
Please observe the expiry date on the
sealant bottle.<

hand side of the cargo bay on the battery cover.
Coupe: access to the Mobility Set
1.Turn the quick-release fastener counter-
clockwise.

Using the M Mobility System
To repair a flat tire with the M Mobility System,
proceed as follows:
>Fill sealant into wheel
>Distribute sealant
>Restore tire inflation pressure
Filling sealant into wheel
Strictly adhere to the specified order, oth-
erwise highly pressurized sealant could
escape.<
1.Shake sealant bottle.
2.Screw hose9 onto connection of sealant
bottle.
3.Unscrew and remove dust cap from valve of
defective wheel and screw filler hose2 of
sealant bottle onto valve.
4.Insert sealant bottle on compressor hous-
ing so that the bottle is in an upright posi-
tion.
5.Make sure that the device is switched off,
position 0.
6.Insert connector 3 into cigarette lighter
socket inside the vehicle.
7.With the ignition switched on:
Switch on the device and allow it to run for
approx. 3 minutes to fill the wheel with seal-
ant. It is not important what inflation pres-
sure the tire has after this.
8.Switch off device.
9.Remove connecting hoses from connection
of sealant bottle and tire valve.Stow the M Mobility System in the vehicle
again.
Distributing sealant
Immediately drive approx. 2 miles/3 km so that
the sealant is evenly distributed in the tire.
Do not exceed a speed of 35 mph or
60 km/h. Do not drive slower than 12 mph
or 20 km/h if possible.<
Restoring tire inflation pressure
1.After approx. 2 miles/3 km, pull over at a
suitable location.
2.Screw compressor hose9 directly onto tire
valve.
3.Insert connector 3 into cigarette lighter
socket inside the vehicle.
4.Correct tire inflation pressure to 29 psi/
200 kPa. With the ignition switched on:
>To increase inflation pressure: switch on
the compressor, position I. Switch off
the device briefly to check the tire's cur-
rent inflation pressure.
Do not allow the compressor to run
for more than 10 minutes, otherwise
the device will overheat and may be dam-
aged.<
>To reduce inflation pressure: press but-
ton 8.
if the inflation pressure is not maintained,
drive the vehicle again, refer to Distribut-
ing sealant. Then repeat steps 1 to 4 once.
Using the M Mobility System can be ineffective
with tire punctures larger than approx. 1/6 in/
4 mm. Please contact the nearest BMW Center
or a workshop that works according to BMW
repair procedures with correspondingly trained
personnel if the tire cannot be made ready for
driving with the M Mobility System.<
The tire inflation pressure must be at least
29 psi/200 kPa. Otherwise do not con-
tinue driving.<
