are already shown there before a signal tone
sounds. The setting is stored for the remote
control currently in use.
iDrive, for explanation of principle, refer to
page16.
1.Open the start menu.
2.Press the controller to open the menu.
3.Select "Vehicle settings" and press the
controller.
4.Change to upper field if necessary. Turn the
controller until "PDC" is selected and press
the controller.
5.Select "PDC display on" and press the con-
troller.
The PDC screen is activated.
The display appears on the Control Display as
soon as PDC is activated.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstacles always remains with
the driver. Even when sensors are involved,
there is a blind spot in which objects cannot be
detected. This applies especially in those cases
where the system approaches the physical con-
straints of ultrasonic measurement, as occurs
with tow bars and trailer couplings, and in the
vicinity of thin or wedge-shaped objects. Low
objects already displayed, e.g. a curb, can dis-
appear from the detection area of the sensors
again before a continuous tone sounds. Higher,
protruding objects, e.g. ledges, cannot be
detected. Loud noises from outside and inside
the vehicle may prevent you from hearing the
PDC signal tone.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during hard braking. This increases active
driving safety.
ABS is operational every time you start the
engine. For information on safe braking, refer to
page99.
CBC Cornering Brake Control
This system provides further enhancements to
vehicle stability and steering response when
braking while cornering or when braking during
a lane change.
Electronic brake-force distribution
This system controls the brake system's appli-
cation pressure at the rear wheels to ensure
stable deceleration.
DBC Dynamic Brake Control
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability Control
DSC optimizes the vehicle stability and traction.
It also detects unstable driving states such as
understeering and oversteering, and helps
keep the vehicle on course within the physical
limits by reducing the engine output and by
braking at the wheels.
The DSC is operational every time you start the
engine.

Wheels and tires

Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one-half, 1γ, times as well on the govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may
depart significantly from the norm due to varia-
tions in driving habits, service practices and dif-
ferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
These grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.<
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and foreign objects lodged in
the tread, and check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm. At tread depths below 0.12 in/
3 mm, there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
Winter tires noticeably loose their suitability for
winter use below a tread depth of 0.16 in/4 mm.
New tires should be mounted in the interest of
safety.
