panied by a rhythmic clicking sound
from the relay).
If the indicator lamp and the clicking
from the relay are both faster than nor-
mal, one of the turn indicators has
failed.To signal brieflyPress the lever up to but not beyond the

0 Wipers retractedThe wipers are partially hidden behind
the hood. To bring the wipers up into
their vertical position (important when
changing the blades, or folding up
when frost is expected):
With the control lever in position 1,
switch off the ignition when the wipers
are in the parked position.
Fold the wipers down onto the
windshield before you turn the ig-
nition key to position 1 or 2.<
For changing the wiper blades, refer to
page 162.1 Interval time or rain sensor
*
You can set the wipe interval to 4
stages with rotary dial 6.
In addition, the wipe interval automati-
cally adapts to variations in 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

Temperature gauge Service Interval DisplayBlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to con-
firm that the system is operational.
Lights up while driving, or the message
"COOLANT TEMPERATURE” appears
in the Check Control: the engine is
overheated. Switch the engine off im-
mediately and allow it to cool down.380de007
Between the blue and red zonesNormal operating range. It is not un-
usual for the needle to rise as far as the
edge of the red zone in response to
high outside temperatures or severe
operating conditions.
Checking coolant level: Refer to

and offPress the button (arrow).
If you want the interior lamps to remain
off continuously, maintain pressure on
the button for approximately 3 seconds.
Press the button briefly to revert to nor-
mal operation.
The orientation lamps on the right and
left of the button for interior lamps
come on when the side lamps are
switched on.380us640

Automatic climate controlResidual heat mode
The heat which is stored in
the engine is utilized for
heating of the interior when the engine
has been switched off (while waiting at
a railroad crossing, for instance).
In ignition key position 1, you can alter
the settings of the automatic climate
control. In ignition key position 0, the
system automatically directs heated air
to the windshield, side windows and
footwells.
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 vent outlets for the
upper body area for individual selection
of air-flow rates and directions:
You can open and close the ventilation
outlets with infinitely-variable adjust-
ments and direct them up or down with
the rotary dials 1. In the closed position,
air exits only at the upper center of the
instrument panel. You can use rotary di-
als 2 to adjust the flow direction from
side to side.
Set the outlets so that the air flows past
you and is not directed straight at you.380de051
Rotary dial 3 allows you to temper the
air flow from these outlets by adding
heat or cooling as desired:
>Turn toward blue – colder
>Turn toward red – warmer
To adjust the rear compartment vents:
Use the rotary dial on the left to close or
open the vent for any desired air flow.
You can adjust the temperature with the
right rotary dial in the same manner as
the adjustment for the front ventilation
outlets.
Use the levers at the centers of the vent
outlets to control the direction of the
emerging air.

Coolant
Do not add coolant to the cooling
system when the engine is hot.
Escaping coolant can cause burns.
To avoid the possibility of damage later
on, never use anything other than fac-
tory-approved, nitrite and amino-free
extended-duty antifreeze with corrosion
protectant. Your authorized BMW cen-
ter is familiar with the official specifica-
tions.
Antifreeze and anti-corrosion agents
are hazardous to health. Store anti-
freeze and anti-corrosion agents in their
original containers where they are inac-
cessible to children.
Extended-duty antifreeze with corrosion
inhibitor contains ethylene glycol - a
flammable substance. For this reason,
do not spill antifreeze with corrosion in-
hibitor on hot engine components. It
could catch fire and cause serious
burns.<
Correct coolant level when the engine
is cold (approx. 687/206):
Unscrew the cap from the expansion
tank.
The coolant level is correct when the
end of the red float is aligned with the
upper edge of the filler opening (refer to
the arrow in the illustration or the sche-
matic diagram next to the cap).
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.380de081
To add coolantWait until the engine cools before re-
moving the cap from the expansion
tank. The needle of the coolant temper-
ature gauge in the instrument cluster
must be located in the blue zone; other-
wise, there is a danger of scalding.
1 Start by turning the cap counter-
clockwise. Pause to allow any accu-
mulated pressure to escape, then re-
move the cap
2 If the coolant is low, slowly add cool-
ant until the correct level is reached –
do not overfill.
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.<
