Driving
72 defective; if a trailer is attached, this could
also indicate that one of its turn signal
bulbs is defective.

initial position when released.<
1 Standard wiper speed
The system automatically reverts to opera-
tion in the intermittent mode whenever the
vehicle is stationary.
Fast wiper speed
You can also select this position by press-
ing the lever upward beyond the resistance
point.
The system automatically reverts to opera-
tion in the standard wipe mode whenever
the vehicle is stationary.
4 Cleaning windshield
The system sprays washer fluid against the
windshield and activates the wipers for a
brief period.
Headlamp washers
Each fifth time you press into position 4 to
clean the windshield while the headlamps
are on.
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do so, your vision could
be obscured. To avoid freezing, use a
washer fluid antifreeze, refer to page73.
Avoid activating the washer when the res-
ervoir is empty, as damage to the pump
could result.<
Windshield washer nozzles
The windshield washer nozzles and the
windshield itself in the area around the wip-
ers are heated automatically when the igni-
tion is switched on.
Rain sensor
The rain sensor is located on the wind-
shield, directly in front of the interior rear-
view mirror.
Activating rain sensor
Briefly press the button as of ignition in
radio mode. The indicator lamp comes on.
The wipers will always respond by com-
pleting at least one sweep of the wind-
shield.
Adjusting rain sensor sensitivity level
Turn the serrated dial 5.
Deactivating rain sensor
Briefly press the button again. The indicator
lamp goes out.

Technology for comfort, convenience and safety

PDC with visual warning
You also enjoy the option of having the sys-
tem show distances to objects on the Con-
trol Display. The Control Display will also
indicate the presence of objects in green
before they are close enough to generate a
signal tone.
Select "PDC pic." from the "Settings" menu
and confirm your selection. This activates
the PDC display.
The display then appears on the Control
Display whenever the PDC is automatically
or manually activated.
The previous display automatically reap-
pears after the system is deactivated.
confirm to return to the previous dis-
play.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always
remains with the driver. Even when sensors
are involved, there is a blind spot in which
objects cannot be detected. The system is
also subject to the physical limits that apply
to all forms of ultrasonic measurement,
such as those encountered with tow bars
and trailer couplings, as well as thin and wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside the
vehicle may prevent you from hearing the
PDC's signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away
from the sensors.<
Driving stability control
systems
Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on DSC and ABS.
ABS Antilock Brake System
ABS enhances active safety by preventing
the wheels from locking under braking.
ABS incorporates CBC and EBV.
Malfunction
The warning lamp lights up yellow
and ABS is switched off. Conven-
tional braking efficiency remains
available without limitations. Have the sys-
tem checked as soon as possible.
CBC Cornering Brake Control
CBC is a supplement to ABS. It provides
further enhancements in vehicle stability
and steering response during lane changes
and cornering at high rates of lateral accel-
eration.

Things to remember when driving
124 ensured that the radiation which results
during transmission will be discharged
from the vehicle interior.<
Cargo loading
To avoid loading the tires beyond
their approved carrying capacity,
never overload the vehicle. Overloading
can lead to overheating and increases the
rate at which damage develops inside the
tires. The ultimate result can assume the
form of a sudden air loss.<
Determine loading limit
1.Locate the following statement on your
vehicle's door pillar
*:
The combined weight of occu-
pants and cargo should never
exceed XXX lbs. or YYY kg, as other-
wise the vehicle may be damaged and
unstable driving conditions may
result.<
2.Determine the combined weight of the
driver and passenger that will be riding
in your vehicle
3.Subtract the combined weight of the
driver and passenger from XXX lbs. or
YYY kg
4.The resulting figure equals the available
amount of cargo and luggage load
capacity.
For example, if the XXX amount equals
1,400 lbs. and there will be five 150-lbs.
passengers in your vehicle, the amount
of available cargo and luggage load
capacity is 650 lbs.:
1,400 Ibs. minus 750 Ibs. = 650 Ibs.5.Determine the combined weight of lug-
gage and cargo being loaded on the
vehicle. That weight should not exceed
the available cargo and luggage load
capacity calculated in step 4
6.If your vehicle will be towing a trailer,
part of the load from your trailer will be
transferred to your vehicle. Consult the
manual for transporting a trailer to
determine how this may reduce the
available cargo and luggage load
capacity of your vehicle.
Load
The permitted load is the total of the weight
of occupants and cargo/luggage. The
greater the weight of occupants, the less
cargo/luggage can be transported.
Stowing cargo
>Load heavy cargo as far forward and as
low as possible, placing it directly
behind the bulkhead behind the rear
seats
>Cover sharp edges and corners
>For very heavy cargo when the rear seat
is not occupied, secure each safety belt
in the opposite buckle.

Replacing components

Light-emitting diodes LEDs
Light-emitting diodes installed behind
translucent lenses serve as the light source
for many of the controls and displays in
your vehicle. These light-emitting diodes,
which operate using a concept similar to
that applied in conventional lasers, are offi-
cially designated as Class 1 light-emitting
diodes.
Do not remove the covers, and never
stare into the unfiltered light for sev-
eral hours, as irritation of the iris could
result.<
Changing wheels
Safety precautions to observe in the
event of a flat and during all tire
changes:
Park the vehicle as far as possible from
passing traffic. Park on a firm, flat, surface.
Switch on the hazard warning flashers.
Engage the parking brake and move the
transmission's selector lever to P.
Have all vehicle occupants get out of the
vehicle and ensure that they remain outside
the immediate area in a safe place, such as
behind a guardrail.
If a warning triangle or portable hazard
warning lamp is required, set it up on the
roadside at an appropriate distance from
the rear of the vehicle. Comply with all
safety guidelines and regulations.
Change the wheel only on a level, firm sur-
face which is not slippery. The vehicle or
the jack could slip to the side if you attempt
to raise the vehicle on a soft or slippery sur-
face such as snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar
object as a support base for the jack, as
this would prevent it from extending to its
full support height and reduce its load-
carrying capacity.
To avoid serious or fatal injury: never lie
under the vehicle, and never start the
engine while it is supported by the jack.<
What you will need
To avoid rattling noises, note the positions
of the tools before removing them, then
return them to their initial positions after
completing work.
>Lug wrench
Located beside the spare tire
>Wheel chock
The chock is located next to the spare
tire, or behind the trim panel on the left
side of the luggage compartment on
vehicles equipped with a trailer cou-
pling.
Remove the floor mat and the cover
above the spare tire.
Unscrew the wingnut and remove the
wheel chock
>Vehicle jack
Located in the luggage compartment
behind the right-hand side panel.
