2002 SAAB 9-5 light

192 Car care and technical informationORVR (Onboard Refueling Vapor
Recovery)Hydrocarbon vapors formed when refueling
will be recovered by the car and not
released into the atmosphere. The hydro-
carbons are absorbed in a evaporative
emission canister. When the engine is sub-
sequently started, the evaporative emission
canister is gradually purged as air is sucked
into it through a shut-off valve. The hydro-
carbon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked at least 3 times. Otherwise, it is pos-
sible for the CHECK ENGINE light to illumi-
nate and a ”TIGHTEN FUEL FILLER CAP”
message to appear on SID.
Refueling, see page 152.
Engine2.3-liter engineThe 2.3-liter model is a transverse, 4-cylin-
der in-line engine with twin overhead cam-
shafts and 4 valves per cylinder.
This engine is equipped with balance shafts
that reduce engine vibration to a minimum.
The balance shafts are chain driven and
rotate at twice the speed of the crankshaft.
They produce forces and torques that are
opposed to those generated by the pistons
and connecting rods, an effect that occurs
twice for each revolution of the engine.
Engine noise is also reduced as the
counter-rotating shafts counteract the vibra-
tion from the moving parts of the engine.
The transmission, located on the right
(viewed from the front), is integrated with
the engine. All models have front-wheel
drive.
3.0t V6 engine The 3.0-liter engine is a transverse, V6
engine with each bank of cylinders having
double overhead camshafts and 4 valves
per cylinder.
The transmission, located on the right
(viewed from the front), is integrated with
the engine. All models have front-wheel
drive.

203 Car care and technical information
WashersThe washer-fluid reservoir holds 6.4 quarts
(6 liters). When "WASHER FLUID LEVEL
LOW" comes up on the SID, the reservoir is
down to about 1 quart (1 liter) of fluid. Add
at least 50% of washer- fluid to water to pre-
vent freezing and for effective cleaning.
WARNING
Take care not to spill washer fluid concen-
trate onto hot surfaces as this constitutes
a fire hazard.

204 Car care and technical informationChanging bulbs Check that the new bulb is working when finished.
Some bulbs are of the ”Long-Life” type. Make sure the same type is
fitted when changing one of these.
Headlight aiming, see page 239.
Xenon headlight (certain models only)Xenon headlights produce roughly twice 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 comprises two sensors on the front axle, one on the rear axle
and a control unit under the headlight housing. Headlight alignment
is regulated automatically to prevent 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.
Xenon headlights are high tension and must therefore be
changed at an authorized Saab workshop. Work involving
high-tension components is potentially lethal.NOTE 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.
NOTE Do not fit bulbs with a higher rating than 55 W, since the head-
light reflector and the wiring of the car are not designed for a
higher wattage.
 Switch off the ignition before changing a bulb, to avoid possi-
ble short-circuiting.
