202 Car care and technical information
Changing bulbs Check that the new bulb is working when
finished.
Use only "Long Life" bulbs.
Headlight aiming, see page 248.
Xenon headlight
3
Xenon headlights produce roughly twice as
much light as halogen bulbs and have a sig-
nificantly longer service life.
The lamp units consist of a gas discharge
lamp containing xenon. When the lights are
switched on a very high voltage activates
the xenon gas. The lamps soon reach full
intensity.
Cars with xenon headlights have automatic
levelling. The levelling system comprises
two sensors, one on the front axle, one on
the rear axle and a control unit under each
of the two headlight housings. Headlight
alignment is regulated automatically to pre-
vent dazzling oncoming traffic. Alignment is
also adjusted during braking.
WARNING
Before changing a bulb in the engine bay,
switch off the engine to avoid danger of
fingers and hands being injured by
moving parts.
The radiator fan can start up even when
the engine is switched off.

are high voltage
and must therefore be changed at a
workshop. We recommend that you
contact an authorized Saab work-
shop. Work involving high-voltage
components is potentially lethal.
NOTICE
• Since the headlight lenses are made
of plastic, rinse dried-on dirt with
water and allow it time to soften up
before cleaning the lenses. Avoid
rubbing the lenses when dry and
never use solvents.
• Use de-icer spray instead of scraping
the ice off.
NOTICE
• Do not fit bulbs with a higher rating
than 55 W, since the headlight reflec-
tor and the wiring of the car are not
designed for a higher wattage.
• Switch off the ignition before chang-
ing a bulb, to avoid possible short-cir-
cuiting.
• Do not touch the glass of the bulbs
with your fingers. The oil on your skin
can shorten the life of the bulb.
