sure may be necessary and brake pedal
travel may be significantly longer.
Please have the system inspected by
your authorized BMW center.
CHECK ENGINE lamp l
If the indicator lamp comes on
either continuously or intermit-
tently, this indicates a fault in the emis-
sions-related electronic systems.
Although the vehicle remains opera-
tional, you should have the systems
checked by your BMW center at the
earliest possible opportunity.

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.

Automatic climate control
If the windows should fog over in
the recirculated air mode, switch
the recirculated air mode off and in-
crease the air supply as required.<
Rear window defroster
When the rear window de-
froster is activated, the indica-
tor lamp comes on. The rear window
defroster switches off automatically.
Residual heat mode
The heat which is stored in
the engine is utilized for
heating the interior when the engine has
been switched off (while waiting at a
railroad crossing, for instance). In igni-
tion key position 1, you can alter the
settings of the automatic climate con-
trol. In ignition key position 0, the sys-
tem automatically directs heated air to
the windshield, side windows and foot-
wells.
This function may be activated
when the outside temperature is
below approx. 597 (156), the engine
is at operating temperature, and the
battery is adequately charged.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to select the opti-
mum airflow rates and directions for
your personal requirements:
Use rotary dial 1 to open and close the
airflow through an infinitely-variable
range. You can also use the levers 2 to
change the direction of the airflow.
Set the outlets so that the air flows past
you and does not flow directly on you.
Rotary dial 3 allows you to temper the
air flow from these outlets by adding
heat or cooling as desired:
Turn toward blue Ð colder
Turn toward red Ð warmer390de051
Rear passenger area ventilationRotary dial 1 opens the outlets in an in-
finitely-variable range. You can vary the
temperature of the air as it flows out us-
ing rotary dial 3 in the same manner as
for the front rotary dial.
You can change the direction of the air
flow with levers 2.390de354

Coolant Brake fluidAdding coolantWait until the engine cools before re-
moving the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be lo-
cated in the blue zone; otherwise, there
is a danger of scalding.
1 Start by turning the cap counter-
clockwise. Pause to allow any
accumulated pressure to escape,
then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50:50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are re-
quired.
Replace the coolant every four years.If the indicator lamp for the
brake hydraulic system appears
or if the "CHECK BRAKE FLUID"
warning appears in the Check
Control: The brake fluid level is
too low in the reservoir.
The brake fluid reservoir is located
under the microfilter housing on the
driver's side of the car. Should you de-
termine that the brake fluid is low, refer
the problem to your BMW center, who
can trace and rectify any sources of
leakage when refilling the reservoir.
Your BMW center is familiar with the
specifications for approved brake fluids
(DOT 4).
Brake fluid loss results in extended
pedal travel. For this situation, refer to
the notes on page 130.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and
reliability of the brake system, have the
brake fluid changed every two years by
an authorized BMW center. Refer also
to the Service and Warranty Information
Booklet (US models) or to the Warranty
and Service Guide Booklet (Canadian
models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion which is out of reach of children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the "MAX"
mark. The brake fluid could ignite upon
contact with hot engine parts and cause
serious burns.<
Comply with the applicable
environmental laws regulating the
disposal of brake fluid.<
