2014 BMW Z4 brake

The transmission provides assistance in the
following situations:▷Upshifts and downshifts are executed only
when they will result in a feasible combina‐
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by
the system.▷When the vehicle stops, the transmission
automatically shifts down to first gear.▷Shortly before the vehicle slows down to
below the minimum speed of the gear cur‐
rently engaged, the transmission automati‐
cally shifts down without requiring your in‐
tervention.
Shifting down rapidly: even in manual mode,
you can skip several gears to achieve optimal
acceleration. Do so by pressing the accelerator
past the resistance point.
Changing to Drive mode Push the selector lever to the right.
Shifting gears via the selector lever
In manual mode:
▷To shift up, pull back the selector lever.▷To shift down, push it forward.
Shifting gears using the shift paddles
on the steering wheel
The shift paddles allow you to shift gears with‐
out taking your hands off the steering wheel.
You do not need to raise your foot from the ac‐
celerator when doing so.
▷Shift up: pull right shift paddle.▷Shift down: pull left shift paddle.
Gears can be shifted using the shift paddles in
Drive mode or in manual mode.
Gear change in manual mode
When manual mode is active, refer to page 67,
gears can be changed using the shift paddles
or the selector lever.
Gear change in Drive mode The shift paddles can be used to change gears
in Drive mode as well.
Afterwards, if the shift paddles are not used for
some time and vehicle acceleration is insuffi‐
cient, the forward gears are changed again au‐ tomatically.
Launch Control
Launch Control enables you to drive off with an
optimal vehicle acceleration on a high grip road
surface.
Do not use Launch Control too often
Do not use Launch Control too often, as
the higher loads on the vehicle lead to prema‐
ture component wear.◀
Launch Control is available when the engine is
at operating temperature, i.e., after driving con‐
tinuously for at least 6 miles/10 km.

5.The vehicle accelerates when you release
the brake pedal. Keep the accelerator
pressed all the way down.6.The transmission shifts up automatically as
long as the accelerator is pressed all the
way down.
Launch Control only becomes available again
after a certain distance has been driven.
Launch Control can only be used after the
break-in phase, refer to page 128.
To maintain driving stability, activate DSC
whenever possible.
Manually releasing and engaging the

Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv‐
er's responsibility to maintain correct tire pres‐
sure, even if under-inflation has not reached
the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal‐
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the in‐
stallation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to en‐
sure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Brake force display
The concept▷During normal brake application, the brake
lamps light up.▷During heavy brake application, the turn
signals light up in addition.
The brake force display is not activated if the
turn signal function is switched on.

Driving stability control systemsVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system automatically produces the maximum braking
force boost. It thus helps to achieve the short‐
est possible braking distance during full brak‐
ing. This system utilizes all of the benefits pro‐
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.Dynamic Stability Control
DSC
The concept DSC prevents traction loss in the driving
wheels when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Sub‐
ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Activating/deactivating DSC DSC can be deactivated/activated via the DSC
OFF program of the Dynamic Driving Control,
refer to page 100.
For better control The DSC indicator lamp flashes: DSC
is controlling the drive forces and brake
forces.
The DSC indicator lamp lights up: DSC has
failed.Seite 99Driving stability control systemsControls99

Activating COMFORTPress the button repeatedly until
COMFORT is selected in the instru‐
ment cluster.
Displays in the instrument cluster
The selected program is displayed in the in‐
strument cluster.
Drive-off assistant
This system supports driving away on gradi‐
ents. The parking brake is not required.
1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive away
without delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin
rolling back.◀
Servotronic
The concept
The Servotronic varies the steering force re‐
quired to turn the wheels depending on the
speed at which you are driving. Power steering
provides strong support at low speeds, which
means that little effort is needed to turn the
wheels. Power steering support lessens as
your speed increases.
The system works automatically.
Malfunction
Malfunctions are displayed via Check Control,

Cruise control The concept
Cruise control is available for use at speeds of
approx. 20 mph/30 km/h and higher. The car
then stores and maintains the speed that you
specify using the lever on the steering column.
In order to maintain the specified speed, the
system brakes the vehicle when the engine
braking effect is insufficient on downhill gradi‐
ents.
Do not use cruise control
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, for instance:▷On curvy roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀
Manual transmission
You can shift gears while cruise control is acti‐
vated. An indicator lamp notifies you that you
should shift gears when you drive for an ex‐
tended period at very high or very low engine
speeds, or the system is deactivated.

Maintaining current speed
Push the lever, arrow 1, or pull it briefly, ar‐
row 2.
The car's current speed is stored and main‐
tained. It is displayed on the speedometer and briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking ef‐
fect is insufficient on downhill slopes, the sys‐
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow 1, until the desired
speed is reached.
▷Each time the lever is pressed to the point
of resistance, the desired speed increases
by approx. 1 mph/1 km/h.Seite 103Driving comfortControls103
