2008 BMW 525I TOURING windshield

Lamps
110 and low beams, reacting to oncoming traffic,
vehicles ahead of you, and sufficiently lit areas,
e.g. in built-up zones.
Manually switching between high
beams and low beams
If you wish or the situation requires, you can
intervene at any time.
>If the high-beam assistant has switched on
the high beams, but you wish to use the low
beams, just switch on the low beams with
the turn signal lever. This deactivates the
high-beam assistant.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>If the high-beam assistant has switched on
the low beams, but you wish to use the high
beams, simply switch on the high beams as
usual. This deactivates the system and it is
up to you to switch back to low beams.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>When the low beams are on, use the head-
lamp flasher as usual.
System limits
The high-beam assistant is designed to
maximize the amount of time that high
beams can be safely used and to quickly switch
back to low beams when traffic approaches.
The system cannot completely replace driver
intervention when unusual conditions are
encountered. For this reason, switch to low
beams when circumstances so dictate. Failure
to do so can pose a safety risk.<
Below are a few examples of situations in which
the system may not react or may only function
to a limited degree, requiring personal interven-
tion:
>in extremely unfavorable weather condi-
tions such as fog or heavy precipitation
>in sensing road users with poor inherent
illumination such as pedestrians, cyclists,
equestrians, horsedrawn vehicles, railroad or shipping traffic close to the road, and at
deer crossings
>in tight curves, on steep crests or dips, with
cross-traffic, or with partially hidden
oncoming traffic on divided highways
>in poorly illuminated areas and in the pres-
ence of highly reflective signs
>in the low speed range
>when the windshield is fogged up, dirty or
covered with stickers, decals etc. in the area
of the inside rearview mirror
>when the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth slightly moistened with glass
cleaner
Moreover, no system can operate without limi-
tations. High-beam assistant operation is sub-
ject to conditions that may reduce the system's
ability to recognize the difference between
actual vehicle head lamps or tail lamps and, for
example, highly reflective signs, markers, and
streetlights. To be on the safe side, the system
may periodically interpret these situations as
conditions that require low beams. Below are
some of the situations in which premature
switching to low beams can occur:
>approaching large and/or highly reflective
signs
>approaching certain lights, such as drive-
way lighting and porch lights
>approaching certain traffic signals
>approaching large reflective markers
In these situations, the system may interpret
the above conditions as a vehicle ahead requir-
ing a switch to low beams. When the conditions
return to normal, the system will reactivate the
high beams.
The high-beam assistant cannot replace the
driver's responsibility for complying with state
laws on high-beam switching or for adapting to
visibility and traffic conditions.

A congenial climate
The AUTO program offers the optimum air dis-
tribution and air volume for virtually all condi-
tions, refer to AUTO program below. Now you
only need to select an interior temperature
pleasant to you.
The following sections contain more detailed
information on the available setting options.
Most settings are stored for the remote control
currently in use, also refer to Personal Profile
settings on page29.
AUTO program
The AUTO program handles the
adjustment of air volume and air
distribution to the windshield and
side windows, in the direction of
the upper body and in the footwell.
It also adapts your instructions for the tempera-
ture to outside influences throughout the year.
The cooling function is switched on along with
the AUTO program. At the same time, a con-
densation sensor controls the program in such
a way that window condensation is prevented
as much as possible.

Switching cooling function on and off
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature setting.
This function is only available when the engine
is running.
The cooling function helps to avoid condensa-
tion on the window surfaces or to quickly
remove them.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is also switched on with
the AUTO program.
Maximum cooling
Maximally cooled air is obtained as
quickly as possible at an outside
temperature above approx. 327/
06 and with the engine running.At the lowest temperature, the automatic cli-
mate control switches into recirculating air
mode. The maximum air volume flows out of the
vents for the upper body. Therefore, open these
vents for maximum cooling.
AUC Automatic recirculated-air
control/recirculated-air mode
You can respond to pollutants or
unpleasant odors in the immediate
environment by suspending the
supply of outside air. The system then recircu-
lates the air currently within the vehicle. During
AUC operation, a sensor detects pollutants in
the outside air and controls the shut-off auto-
matically.
By pressing the button repeatedly, you can
request three operating modes:
>LED off: outside air flows in continuously.
>Right LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
>Left LED on, recirculated-air mode: the
supply of outside air is permanently shut off.
Should the windows fog up in the recircu-
lated-air mode, press the AUTO button or
switch off the recirculated-air mode and
increase the air volume if necessary.
The recirculated-air mode should not be used
over an extended period of time, as the air qual-
ity inside the vehicle deteriorates continu-
ously.<
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
1.Switch off the engine.
2.Turn to the right, refer to arrow.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine
>with engine at operating temperature

Care
240 ating instructions for the high-pressure clean-
ing jets.<
When using high-pressure cleaning jets,
do not remain in one place for a long time
and be sure to maintain a distance of at least
12 in/30 cm from sensors, e.g. Park Distance
Control sensors or radar sensors.<
Hand washing
When washing the vehicle by hand, use plenty
of water and car washing shampoo. Clean the
vehicle with gentle pressure using a sponge or a
washing brush.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unwanted wiper operation.<
Follow local guidelines for washing vehi-
cles by hand.<
Headlamps
Do not rub dry and never use abrasives or
strong solvents to clean the covers.
Loosen dirt, e.g. insects, with shampoo or
insect remover and wash away with plenty of
water.
Use a window de-icer to remove accumulated
ice and snow, not a scraper.
Windows
Use a glass cleaner to clean the inside and out-
side surfaces of the windows and the glass sur-
faces of the mirrors.
Do not use quartz-containing cleansers
to clean glass surfaces of the mirrors.<
Wiper blades
Clean with soapy water and replace regularly to
prevent streaking.
The presence of wax and sealant residues
and dirt on the windows leads to streaking
during wiper operation and results in premature
wear on wiper blades as well as interference
with the rain sensor.<
Caring for the vehicle finish
Regular care helps your vehicle retain its value
and protects the paint from the long-term
effects of aggressive substances.
Regionally occurring environmental factors can
affect and damage vehicle finish. It is therefore
important to tailor the frequency and extent of
your car care accordingly.
Immediately remove particularly aggressive
substances such as spilled fuel, oil, grease,
brake fluid, tree resin, or bird droppings; other-
wise, they may damage your paint.
Repairing paint damage
Repair stone damage or scratches imme-
diately, depending on the severity of the
damage, to prevent the formation of rust.<
BMW recommends having paint damage pro-
fessionally repaired using Genuine BMW finish
materials in accordance with factory guidelines.
Waxing
Sealant is required when water no longer beads
on the clean surface of the paint. Use only prod-
ucts that contain carnauba wax or synthetic wax
to seal your finish.
Rubber gaskets
Treat only with water or a rubber care product.
To avoid noise or damage, do not use
products that contain silicone to care for
rubber gaskets.<
Chrome components
Particularly after exposure to road salt, thor-
oughly cleanse parts like the radiator grille, door
handles, or window frames with plenty of water
with shampoo added to it. For additional treat-
ment, use chrome polish.
Alloy wheels
Depending on your system, braking can gener-
ate dust, which settles on the light-alloy wheels.
Remove this dust regularly with acid-free wheel
cleaner.

Giving and receiving assistance
256 Sedan:
It is located in the toolkit in the luggage com-
partment lid, refer to page243.
Sports Wagon:
It is located in the toolkit behind the left side
panel in the cargo bay, refer to page243.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing only on roads. Avoid lateral
loading of the tow fitting, e.g. do not lift the vehi-
cle by the tow fitting. Otherwise damage to the
tow fitting and the vehicle can occur.<
Access to screw thread
Press the arrow symbol on the cover in the
bumper.
Front
Rear
Being towed
Make sure that the ignition is switched on,
refer to page61, otherwise the low
beams, tail lamps, turn signals and windshield
wipers would not be available. Do not tow the
vehicle with the rear axle raised, as otherwise
the steering can turn to the left or right. When
the engine is stopped, there is no power assist. This then requires increased effort for braking
and steering. Active steering is deactivated and
larger steering wheel movements are
required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Manual transmission
Gearshift lever in neutral position.
Automatic and sport automatic
transmission
Before towing, manually release the
transmission lock, even if there is no mal-
function in the transmission. Otherwise there is
a risk that the transmission lock will engage dur-
ing towing.<
Manually unlocking and locking transmission
lock, refer to page65.
Do not exceed a towing speed of mph/
70 km/h and a towing distance of
90 miles/150 km; otherwise the automatic
transmission may be damaged.
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts, otherwise damage may
result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
