1 Intermittent wipe or rain sensor*Intermittent wipe:
You can set the wipe interval to four
stages with rotary dial 7.
In addition, the wipe interval is varied
automatically depending on road
speed.
Rain sensor:
When the rain sensor is activated, the
windshield wiper is controlled automati-
cally, depending on the degree of wet-
ness of the windshield (in both snow
and rain). You do not have to be con-
cerned with switching the windshield
wiper on or off or adjusting the wipe in-
terval between intermittent and full
wipe. Instead, you can concentrate fully
on the traffic conditions. This is espe-
cially important under adverse weather
conditions.
The rain sensor is positioned on the
windshield, directly ahead of the interior
rearview mirror.
To activate the rain sensor:
From ignition key position 1 and up,
move the lever to position 1. The wipers
travel once across the windshield,
regardless of the weather.

Wiper/Washer systemYou can leave the lever permanently in
position 1. It is then only necessary to
activate the rain sensor from ignition
key position 1 and up. To do this
>turn rotary dial 7 briefly or
>use either the automatic windshield
washer 5 or the automatic intensive
washer 6.
To modify the sensitivity of the rain
sensor:
Turn rotary dial 7.
Turn the rain sensor off in auto-
matic car washes.
If you do not, damage may occur if the
wipers switch on unintentionally.< 2 Normal wiper speedThe wipers automatically revert to inter-
mittent operation when the vehicle is
stationary (not on vehicles with rain
sensor
*).
3 Fast wiper speedThe wipers automatically revert to nor-
mal speed when the vehicle is station-
ary (not on vehicles with rain sensor
*).
5 Automatic windshield washerThe system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
If you only pull the lever briefly, the sys-
tem sprays washer fluid onto the wind-
shield without activating the wipers.6 Intensive automatic
cleaning unit
*
As in setting 5. In addition, an intensive-
action washer fluid is first sprayed on
the windshield.
For changing the wiper blades, refer to
page 166.
Headlamp washers
*
If they are on, the headlamps will also
be cleaned every fifth time you activate
the automatic windshield washer (inten-
sive-action or standard wash/wipe).
Do not use the washers if there is
any danger that the fluid will
freeze on the windshield, otherwise vi-
sion could be obscured. For this rea-
son, use an antifreeze agent. Refer to
page 148.
Do not use the washers when the reser-
voir is empty, since this could cause
damage to the washer pump. Windshield washer jetsThe windshield washer jets are warmed
automatically when the ignition key is in
position 2.

Caring for your carWashing your carYou can have your new BMW washed
in an automatic car wash. Car wash
systems that do not employ brushes are
preferable.
Wipe away tough dirt and loosen and
remove dead insects before washing
the car.
To prevent spots, avoid washing when
the hood is still warm, or immediately
after and during exposure to strong
sunlight.
When using an automatic car wash, be
sure that:
>The car wash system is suited for the
dimensions of your vehicle
>No damage will occur on vehicles
with attached body accessories (such
as spoilers or antennas). If you are
uncertain, consult the manager of the
car wash
>The wheels and tires of your vehicle
cannot be damaged by the convey-
ance devices of the car wash system
>The vehicle is cleaned with minimum
brush pressure, and that ample water
is available for washing and rinsing.Vehicles with rain sensor
*:
Clean the windshield regularly. Wax
from automatic car washes or insects,
for example, can cause malfunctions in
the function of the rain sensor.
Turn the rain sensor off in auto-
matic car washes. If you do not,
damage may occur if the wipers switch
on unintentionally.<
Parts of the car which are inaccessible
to the automatic washer Ð such as door
sills, door and hood edges, etc. Ð
should be cleaned by hand.
In the winter months, it is especially im-
portant to ensure that the car is washed
on a regular basis. Large quantities of
dirt and road salt are difficult to remove,
and they also cause damage to the ve-
hicle.
If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's sur-
face. Inadequate distance and exces-
sive pressure can damage or weaken
the finish, making it more susceptible to
subsequent attack. In addition, mois-
ture could penetrate to vehicle compo-
nents, leading to long-term damage.<
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth (scratches). Never use abra-
sives or strong solvents to clean the
covers
>Remove dirt and contamination
(such as insects) by soaking with
BMW Car Shampoo and then rinsing
with plenty of water
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use an ice scraper.<
After washing the car, apply the
brakes briefly to dry them. Braking
efficiency might otherwise be reduced
by the moisture, and the brake rotors
could also be corroded.<

Towing the vehicle
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-startingIt is not possible to start the engine of
vehicles equipped with an automatic
transmission by towing or pushing.
For instructions on jump starting, refer
to page 182.
Never attempt to use your vehicle to
push another car, since damage to the
energy-absorbing bumpers could
result.
Towing a vehicle with automatic
transmission1 Place the selector lever in position N
2 Towing speed:
Max. 45 mph (70 km/h)
3 Towing distance:
Max. 95 miles (150 km)
4 Leave the ignition key at position 1 to
ensure that the brake lamps, turn sig-
nals, horn and windshield wipers re-
main operative, and to prevent the
steering lock detent from engaging.
5 Switch on the hazard-warning system
(observe country-specific regula-
tions).
Find some means of identifying the ve-
hicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed to pre-
vent the steering lock from engaging.
The steering and brakes are without
power assist when the engine is off.
This means that increased effort is
required for steering and braking.<
Towing with a commercial
tow truck>Do not tow with sling-type equipment
>Use a wheel lift or flat bed carrier
>Please comply with applicable towing
laws.
Never allow passengers to ride in
a towed vehicle for any reason.<380us124

Rain sensor
*
Depending on the degree of wetness
on the windshield, the rain sensor
controls the operation of the windshield
wipers.
Infrared light is carried along the
surface of the windshield in an optical
conductor in such a manner that it is
reflected completely when the wind-
shield is dry. The quantity of reflected
light is measured.
If the window is covered with beads of
water, the amount of light that is
reflected is decreased since the infra-
red light at the surface of the windshield
can then escape. The quantity of
reflected light is thus a means of
gauging the degree of wetness on the
windshield.390de133
When the system is set to the "Intermit-
tent" wiper speed, the wipers react
immediately Ð if water is splashed onto
the windshield by vehicles traveling
ahead of you, for example. As a result,
the rain sensor provides a contribution
to driving safety and comfort.
