Switches

Daytime Running Lights
(DRL)
When the switch is in the AUTO position,
there is an automatic switch between low-
beam and Daytime Running Lights (DRL)
based on the amount of daylight. Two sen-
sors located at the top of the windshield
detect upward and forward light intensity.
This makes it possible for the system to
automatically perform functions such as
activating low beam when you drive into a
tunnel on a sunny day.
Parking lights are turned off.
In cold and damp weather, the inside of
the headlamp lens may temporarily mist
up. This misting does not affect the func-
tion or service life of the light fitting.
When the lamps are on, the mist will
eventually disappear.
Light switch
Cars with xenon lights: The bulbs for DRL
are in the inner of the two bulb holders in the
bulb housing. The bulb is visible from the
outside.
Cars with halogen lights: These cars do
not have a separate DRL bulb. Low beam
instead shines with reduced output.
A fault in the system will produce the follow-
ing message on the Saab Information Dis-
play (SID):
Automatic light control
malfunction.
Instruments and controls
When the engine is started and the
switch is in the AUTO position
Cars with automatic transmission: DRL
or low beam (which depends on the amount
of daylight) comes on when the gear selec-
tor is moved out of the P position. The light
goes out when the ignition switch is turned
to the OFF position (engine is turned off).
Cars with manual transmission: If the
parking brake is applied when the engine is
started, DRL or low beam (which depends
on the amount of daylight) comes on when
the parking brake is released. Otherwise,
the light comes on when the ignition switch
is turned to the ON position. The light goes
out when the ignition switch is turned to the
OFF position (engine is turned off).
High beam cannot be activated in the DRL
mode but headlight flasher can.
