Xenon light, dipped beam 3
WARNING
Because Xenon lamp unit is under
extremely high voltage, entrust all work on
the unit, including bulb replacement, to a
workshop. We recommend that you con-
tact an authorised Cadillac workshop.
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 suspension
and one on the rear suspension, and a con-
trol unit by the engine bay electrical centre.
Headlight alignment is adjusted automati-
cally to the car's load to prevent dazzling
drivers in oncoming traffic.
If the system malfunctions, the following
message will appear on the DIC:
Headlight levelling
malfunction.
We recommend that you contact an
authorised Cadillac workshop for Xenon
bulb replacement.
