Wrong bulb fitted
If a low or main beam bulb of too high a
rating is fitted, a bulb failure message will be
shown on the SID (a too high wattage bulb
can damage the reflector).
If the following message is displayed but the
bulb shines, it is most likely that an incorrect
bulb has been fitted.
Note
When changing bulbs, fit the same type of
bulb (e.g. Long-Life) as that removed.
Headlight aiming, page 274.
Xenon headlights
3
Xenon headlights produce roughly two
times as much light as halogen bulbs and
have a significantly 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 is comprised
of two sensors, one on the front suspension
and one on the rear suspension, and a con-
trol unit by the engine bay fuse box. Head-
light alignment is adjusted automatically to
the car’s load to prevent dazzling drivers in
oncoming traffic.
If a fault is detected in the system, the fol-
lowing message will be displayed on the
SID:
Right high beam failure.
WARNING
Xenon headlights are high tension. All
work on xenon headlights, including
changing bulbs, must be carried out by
dealer personnel.
Headlight levelling
malfunction.
We recommend you to contact a Saab
dealer to have a xenon headlight changed
