82 until "PDC" is selected and press the con-
troller.
6.Select "PDC display on" and press the con-
troller.
The PDC screen is activated.
The display is shown on the Control Display as
soon as PDC is activated.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e. g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Loud sound sources out-
side or inside the car can drown out the PDC
signal. Therefore, always drive cautiously, oth-
erwise there is a risk of personal injury or prop-
erty damage.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page116.
Electronic brake-force distribution
EBV
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 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 for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions at the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks, as this could
result in an accident.<

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The objective is to optimize
efforts with respect to minimal vehicle mainte-
nance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
Condition Based Service CBS
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
On the Control Display, you can have the
remaining times or distances for selected main-
tenance tasks and any legally prescribed dates
displayed, refer to page72:
>Engine oil
>Brake pads: separately for front and rear
>Brake fluid
>Vehicle check
>Legally mandated inspections depending
on local regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. Your BMW Service Advi-
sor can read out this data from the remote con-
trol unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore hand your
BMW Service Advisor the remote control unit
that you last used.
Make sure that the date is always set cor-
rectly, refer to page76; otherwise the
effectiveness of Condition Based Service CBS
is not assured.<

Please consult your Service and Warranty Infor-
mation Booklet for US models and Warranty
and Service Guide Booklet for Canadian models
for additional information on service require-
ments.
BMW recommends that you have service
and repair operations performed at your
BMW center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance.<

Care
Care products
Regular cleaning and care contributes signifi-
cantly to the value retention of your BMW.
BMW recommends cleaning and caring for your
vehicle with products that are approved by
BMW for this purpose.
Your BMW center will be happy to advise you on
the products and services available for cleaning
and caring for your BMW.
Original BMW CareProducts have been
material tested, laboratory checked and
proven in the field, and offer optimal care and
protection for your vehicle.<
Do not use cleaners that contain alcohol
or solvents as these may result in dam-
age.<
Cleaning agents can contain substances
that are dangerous or hazardous to your
health. Therefore, follow the warning and safety
instructions on the packaging. When cleaning
inside the vehicle, always open the doors or
windows of the vehicle. In enclosed areas, pro-
vide for sufficient ventilation. Only use products
designed for cleaning vehicles.<
Exterior care
Washing the vehicle
Especially during the winter months,
ensure that the vehicle is washed more
frequently. Heavy soiling and road salt can lead
to vehicle damage.<
After washing the vehicle, apply the
brakes briefly to dry them, otherwise
water can reduce braking efficiency over the
short term and brake discs can corrode.<
Automatic car washes
Preference should be given to cloth car washes.Do not use high-pressure car washes,
otherwise water may drip into the vehicle
around the windows.<
Before driving into a car wash, ensure that it is
suitable for your BMW. Check the following:
>Dimensions of your vehicle, refer to
page237.
>If necessary: fold in the exterior mirrors,
refer to page52
>Maximum permissible tire width
>In convertibles, do not treat the convertible
top with wax. Ensure that a program is avail-
able that does not apply wax or is designed
specifically for convertibles.
Preparations before driving into an automatic
car wash:
>Unscrew rod antenna
*
>Deactivate the rain sensor* to avoid unin-
tentional activation of the wipers.
>Remove additional attachments, e.g.
spoiler or telephone antennas, if there is a
possibility that they could be damaged.
Automatic transmission
Before driving into an automatic car wash, per-
form the following steps to ensure that the vehi-
cle can roll:
1.Insert the remote control, even with conve-
nient access, into the ignition lock.
2.Engage transmission position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock
so that the vehicle can roll.
Steam jets / high-pressure washers
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 1407/606.
Insufficient clearance or excessive pressure or
