2003 SAAB 9-5 wiring

181 Starting and driving
Driving in hot weather Always check the coolant level before
starting a journey. The level should be just
below the MAX mark.
 At the end of a journey, if the engine has
worked hard, allow it to idle for two or
three minutes before switching it off.
If the needle on the temperature gauge
enters the red zone:
1 Bring the car to a standstill but leave the
engine running. Do not remove the cap
on the expansion tank even if the tank is
empty. If the needle on the temperature
gauge continues to rise while the engine
is idling, switch off the engine. 2 Wait until the needle has dropped back
to indicate normal temperature (roughly
midway, in the white zone) before stop-
ping the engine. If the coolant needs top-
ping up, unscrew the cap on expansion
tank carefully.
Top up, as necessary, ideally with a
50/50 mixture of Saab-approved coolant
and water. If only water is available, use
that, but remember to have the coolant
mixture checked as soon as possible.
3 As soon as possible, have the cooling
system checked by an authorized Saab
dealer.
Towing a trailerTrailer hitch attachmentTrailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs. (1588 kg),
see also page 259.
Use only the electrical trailer hitch socket
provided in the trailer hitch kit.
Saab recommends:
 Use a Saab original hitch kit attachment
which is designed and tested by Saab.
 Consult your Saab dealer regarding the
appropriate hitch kit for your car.
WARNING
 Exercise care when opening the hood
if the engine is overheated. Never
remove the expansion tank cap com-
pletely when the engine is hot.
 The cooling system is pressurized -
hot coolant and vapor can escape.
These can cause injury to your eyes
and burns. Open the cap slowly to
release the pressure before
removing it.
NOTICEUse only a genuine Saab trailer hitch and
wiring, since other wiring methods can
cause expensive damage to the car’s
body and electrical system.
Consult an authorized Saab dealer for
guidance on how to connect the trailer
hitch electrical system.

214 Car care and technical informationChanging bulbsCheck that the new bulb is working when finished.
Use only "Long Life" bulbs.
Headlight aiming, see page 250.
Bi-Xenon headlight (certain models only)Bi-Xenon headlights produce roughly twice as much light as halo-
gen 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.
Bi-Xenon headlights are high voltage and must therefore be
changed at an authorized Saab workshop. 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 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.
 Do not touch the glass of the bulbs with your fingers. The oil
on your skin can shorten the life of the bulb.
