in spite of the fact that the tire is filled to the cor‐
rect inflation pressure.
The system is deactivated and is unable to de‐
tect flat tires if a wheel not equipped with TPM
electronics has been mounted, e.g., a compact
wheel, or if TPM is experiencing temporary in‐
terference from other systems or devices that
use the same frequency.
Resetting the system
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
Operating principle, refer to page 62.1.Start the engine, but do not start driving.2.Lightly push button 1 in the turn indicator
lever up or down repeatedly until the appro‐
priate symbol appears in the display, ac‐
companied by the word "RESET".3.Press button 2 to confirm your choice of the
Tire Pressure Monitor.
The following display appears:4.Press button 2 for approx. 5 seconds until
the small warning lamp lights up yellow and
the following display appears:5.Drive away.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the
target values to be monitored. The system
reset is completed during your drive, and
can be interrupted at any time. When driving
resumes, the reset is continued automati‐
cally. The indicator lamp goes out after the
system reset is completed.
Low tire pressure message
The warning lamps come on in yellow
and red. In addition, a signal sounds.
▷There is a flat tire or a major loss in
tire inflation pressure.▷The system was not reset after a wheel
change and thus issues warnings based on
the inflation pressures initialized last.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with reg‐
ular tires or run-flat tires.
Run-flat tires , refer to page 160, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.Seite 78ControlsSafety78

Park Distance Control PDC
The concept
PDC supports you when parking.
Objects in front of or behind your vehicle that
you are approaching slowly are indicated by
acoustic signals.
Measurement
Measurements are made by ultrasound sensors
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 vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
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 physical
limits of ultrasonic measurement, for instance:▷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 garages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
Engage reverse gear with the engine running or
the ignition switched on.
Switching off automatically when
driving forward
The system switches off when a certain distance
or speed is exceeded.
Switch on the system again if necessary.

Close both windows
An open window causes higher air resistance
and thus increases fuel consumption.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire inflation
pressure, refer to page 155, at least twice a
month and before starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehicle
driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.
Avoid high engine speeds
Use 1st gear to get the vehicle in motion. Be‐
ginning with 2nd gear, accelerate rapidly. When
accelerating, shift up before reaching high en‐
gine speeds.
When you reach the desired speed, shift into the
highest applicable gear and drive with the en‐
gine speed as low as possible and at a constant
speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use coasting conditions
When approaching a red light, take your foot off
the accelerator and coast to a halt in the highest
applicable gear.On a downhill slope, take your foot off the ac‐
celerator and coast in a suitable gear.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer
stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Fuel savings are achieved after the vehicle is
switched off for only approx. 4 seconds.
The Automatic Engine Start/Stop Function au‐
tomatically switches the engine off during a
stop. Additional information on the Automatic
Engine Start/Stop Function, refer to page 47.
Switch off any functions that are not
currently needed
Functions such as the automatic climate control
require a large amount of energy and consume
additional fuel, especially in city and stop-and-
go traffic.
Therefore, switch off these functions if they are
not actually needed.
Have maintenance carried out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
Have the maintenance carried out by your serv‐
ice center.
Please also note the BMW Maintenance Sys‐
tem, refer to page 168.Seite 113Things to remember when drivingDriving tips113
