5Adjusting rain sensor sensitivity level
Switching on wipers
Pull the lever upward, arrow1.
The lever automatically returns to its initial posi-
tion when released.
Normal wiper speed
Press once.
The system reverts to operation in the intermit-
tent mode when the vehicle is stationary.
Fast wiper speed
Press twice or press beyond the resistance
point.
The system reverts to normal speed when the
vehicle is stationary.
Rain sensor
The wiper operation is controlled automatically
as a function of the rain intensity. The rain sen-
sor is located on the windshield, directly in front
of the interior rearview mirror.
Activating rain sensor
Press the button, arrow3. The LED in the but-
ton lights up.
Adjusting rain sensor sensitivity level
Turn the knurled wheel5.
Deactivating rain sensor
Press the button again, arrow3. The LED goes
out.
Deactivate the rain sensor when passing
through an automatic car wash. Failure to
do so could result in damage caused by undes-
ired wiper activation.<
Cleaning windshield, headlamps* and
BMW Night Vision camera*
Pull the lever, arrow4.
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
With the vehicle lighting switched on, the head-
lamps and the BMW Night Vision camera are
also cleaned simultaneously at suitable inter-
vals.
Do not use the washing mechanisms 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 Washer
fluid. Do not use washing mechanisms when
the washer fluid reservoir is empty, otherwise
you will damage the washer pump.<

Giving and receiving assistance
250 Sedan:
It is located in the toolkit in the luggage com-
partment lid, refer to page237.
Sports Wagon:
It is located in the toolkit behind the left side
panel in the cargo bay, refer to page237.
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.

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 automati-
cally be engaged during towing.<
Manually unlocking and locking transmission
lock, refer to page65.
Do not exceed a towing speed of 45 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.
