96 Instruments and controls
Control for setting wiper delay
Rain sensor (option)
WARNING
Turn the rain sensor off if the ignition is
ON to avoid personal injury when clearing
snow and ice from the windshield.
NOTICE
Turn the rain sensor off before washing
the car in an automatic carwash, to avoid
damaging the windshield wipers.
The rain sensor automatically controls the
windshield wipers. The sensor is located on
the windshield beside the rearview mirror.
The system varies the frequency of wiping
between single sweeps and continuous
wiping, depending on the amount of pre-
cipitation.
Activate the rain sensor by lifting the stalk
switch to the AUTO position. The wipers
make one sweep for reference to see how
much water is on the windshield. In the
future, the sensor compares the amount of
water on the windshield with this reference
value.
Windshield wipers with rain sensor
0 OFF
1 Single sweep
2 AUTO - rain sensor engaged
3 Low speed
4 High speed
5 Windshield and headlight washing (certain
variants only)
If the stalk switch is left in the AUTO position
when the engine is switched off, when the
engine is next started it must first be moved
to the 0 or 3 position and then back to AUTO
to reactivate the sensor.
If the system malfunctions, the wipers will
operate at low speed when the stalk switch
is set to the AUTO position.
