Changing bulbs

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.

Xenon headlights 3 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.

Check that the new bulb is working when fin- ished.

Use only "Long Life" bulbs.

Headlight aiming, see page 247.

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.

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 on the front axle, one on the rear axle and a control unit under the head- light housing. Headlight alignment is regu- lated automatically to prevent dazzling oncoming traffic. Alignment is also adjusted during braking.
