2015 BMW Z4 Warning lights

Low tire pressure messageThe warning lights come on in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds.▷There is a flat tire or a major loss in tire in‐
flation pressure.▷The system was not reset. The system
therefore issues warnings in case of devia‐
tions from the tire inflation pressures
stored last.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 98, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
Actions in the event of a flat tire Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. Reset the system.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
The use of tire sealant can damage the
TPM electronics. In this case, have theelectronics checked at the next opportu‐
nity and have them replaced if necessary.
Run-flat tires
You can continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at
the next opportunity.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. Reset the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx.
50 miles/80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e. g., curbs, potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending on the driving speed, road
conditions, external temperature, cargo load,
etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.

A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering
properties.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of the tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving, and contact your service
center.◀
Message when not reset The warning light lights up yellow. A
Check Control message is displayed.
The system may not have been reset
although a wheel was changed.
Check the tire inflation pressure and reset the
system, refer to page 97.
System limits
The system does not function properly if it has
not been reset, e.g., it may identify a tire as flat
in spite of the fact that the tire is filled to the
correct inflation pressure.
The tire pressure depends on the temperature
of the tire. An increase in the tire temperature,
e.g., while driving or due to sunlight, increases
the tire inflation pressure. The tire pressure
decreases when the tire temperature drops. In
case of severe temperature drops, this behav‐
ior may lead to a warning on account of the de‐
fined warning limits.
Malfunction The small warning light flashes in yel‐
low and then lights up continuously;
the larger warning light comes on in
yellow. On the Control Display, the
tires are shown in gray and a message ap‐
pears. No flat tire can be detected.Display in the following situations:▷A wheel without TPM electronics is fitted:
have the service center check it if neces‐
sary.▷Malfunction: have the system checked by
your service center.▷TPM could not be fully reset. Reset the
system again.
The small warning light flashes in yel‐
low and then lights up continuously;
the larger warning light comes on in
yellow. The tires are displayed in gray
on the Control Display. No flat tire can be de‐
tected.
Display in the following situations:
▷Disturbance by systems or devices with
the same radio frequency. After leaving the
area of the disturbance, the system auto‐
matically becomes active again.
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‐

Park Distance Control PDC
The concept PDC supports you when parking.
You are alerted that you are slowly approach‐
ing an object behind the vehicle and, if equip‐
ped accordingly, in front of the vehicle by:▷Signal tones.▷A visual display.
Measurement
Measurements are made by ultrasound sen‐
sors in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷By the front sensors and two rear corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
System limits
Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an acci‐
dent could result from road users or objects
located outside of the PDC detection range.
Loud noises from outside and inside the vehi‐
cle may prevent you from hearing the PDC's
signal tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physi‐
cal limits of ultrasonic measurement, for in‐
stance:▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With low objects.▷With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before
or after a continuous tone sounds.
High, protruding objects such as ledges may
not be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground ga‐
rages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.Seite 107Driving comfortControls107
