Washer/wiper system and
rain sensor*
0Wipers retracted
1Intermittent operation or rain sensor
2Normal wiper speed
3Fast wiper speed
4Brief wipe
5Rotary dial for control of the wipe inter-
val or the sensitivity of the rain sensor
Intermittent operation
Not on vehicles with rain sensor.
You can set the wipe interval over four
stages with rotary dial 5.
In addition, the wipe interval is varied auto-
matically depending on road speed.
Rain sensor
The rain sensor is positioned on the wind-
shield, directly behind the interior rearview
mirror.
To activate the rain sensor:
>With the ignition key in position 1 or
higher, move the lever to position 1. The
wipers travel once across the wind-
shield, regardless of the weather.
You can leave the lever permanently in
position 1. With the ignition key in
position 1 or higher, it is then only neces-
sary to activate the rain sensor. To do this
>turn rotary dial 5 briefly.
To adjust the sensitivity of the rain sensor:
turn rotary dial 5.
To deactivate the rain sensor:
return lever to position 0.Turn the rain sensor off in automatic
car washes. Failure to do so could
result in damage caused by undesired
wiper activation.<
Normal wiper speed
When the vehicle is stationary, the wipers
automatically switch to intermittent wipe –
not on vehicles with rain sensor.
Fast wiper speed
When the vehicle is stationary, the wipers
operate at normal speed – not on vehicles
with rain sensor.

1Cleaning windshield and headlamps
*
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield, otherwise vision could be
obscured. For this reason, use an anti-
freeze agent. Refer to page 79.
Do not use the washers when the reservoir
is empty. Otherwise damage to the washer
pump could result.<
Cleaning the windshield
The system sprays washer fluid against the
windshield and activates the wipers for a
brief period.
Cleaning the headlamps
When the vehicle's lighting system is
switched on, the headlamps are cleaned at
reasonable intervals.

Washer fluids for washer
systems
Headlamp* and windshield washer
system
Capacity of windshield washer system:
approx. 3.2 US quarts / 3 liters.
Capacity when equipped with headlamp
washer system: approx. 5.3 US quarts /
5 liters.
Fill with water and – if required – with an
antifreeze agent according to the manufac-
turer's recommendations.
We recommend that you mix the
washer fluid before adding it to the
reservoir.<
Antifreeze agent for the washer sys-
tems is flammable. For this reason,
keep it away from sources of flame and
store it only in its original container. Store it
so that it is inaccessible to children. Com-
ply with the instructions on the contain-
ers.<
Engine oil
Engine oil pressure
The red engine oil warning lamp
lights up:
Stop the vehicle immediately and
switch off the engine. Check the engine oil
level and top off as required. If the oil level
is correct, please contact the nearest BMW
center.
Do not continue driving, as the engine
could sustain serious damage from
inadequate lubrication.<
Engine oil level
The yellow engine oil indicator lamp
lights up while driving:
The oil level is at the absolute mini-
mum; refill as soon as possible. Do not
drive more than approx. 30 miles / 50 km
until you do.
The yellow engine oil indicator lamp
lights up after the engine is
switched off: add engine oil at the
earliest opportunity, when you stop to
refuel.
Engine oil sensor
The yellow engine oil indicator lamp
lights up within 20 seconds after
the engine is started:
The oil level sensor is defective. Please
have it checked by a BMW center.
Checking the oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature
3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil level should be between the two
marks on the dipstick
6.Return the dipstick to the guide tube,
inserting it as far as it will go.
As with fuel economy, oil consumption is
directly influenced by your driving style and
vehicle operating conditions.
