2006 SAAB 9-5 engine

204 Car care and technical informationDrive belts
The alternator is situated on the right-hand
side of the engine, adjacent to the bulkhead.
It is driven via a Poly-V-belt from the crank-
shaft pulley.
The Poly-V-belt also drives the water pump,
the A/C compressor and the steering servo
pump.
The belt tension is critical and is adjusted
automatically by the belt tensioner.
See also page 59, ”Warning, charging”.
WARNING
 Keep hands and clothing clear of drive
belts when engine is running.
 Always stop the engine before
inspecting drive belt.
 The radiator fan is electric and can
start even when the engine is
switched off.NOTICESerious damage can be done to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.

207 Car care and technical information
Changing bulbsCheck that the new bulb is working when finished.
Use only "Long Life" bulbs.
Headlight aiming, see page 250.
Xenon headlight




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 voltage and must therefore be
changed at a workshop. We recommend that you contact 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.

220 Car care and technical informationMaxi fusesThe Maxi fuses are housed in the fuse box
under the hood. These fuses can be
checked in the same way as the other fuses.
The Maxi fuses are designed to protect the
car’s electrical system from being dam-
aged. Each Maxi fuse protects a number of
electrical circuits and functions and there-
fore has a higher rating (amperage) than the
standard fuses. No spare Maxi fuses are
supplied with the car.
DICE / TWICEDICE = Dashboard Integrated Central Elec-
tronics
TWICE = Theft-Warning Central Electronics
DICE and TWICE are electronic control
modules that monitor and control a variety
of functions:
DICE controls (among other things):
 Front lights and interior lighting
 Instrument illumination
 Intermittent wiper operation
 Electric heating of rear window and door
mirrors
 Cooling fans
TWICE controls (among other things):
 Central locking.
 Car alarm (Anti-theft system)
 Engine immobilizer
 Autochecking of lights.
 Electric heating of rear seat
 Safety belt reminder
 Electrically adjustable passenger seatThe DICE and TWICE control modules are
linked to a data bus, which is basically an
information carrier that allows information to
be exchanged between all the control mod-
ules and components connected to the bus.
If a fault occurs in any of these components,
diagnostic faults codes are set in the rele-
vant control module, which facilitates fault
diagnosis. We recommend that you contact
an authorized Saab dealer.
The scan tool connector for fault diagnosis
is located under the instrument panel on the
drivers side.
NOTICEIf a Maxi fuse blows, it means that there is
a major fault in the electrical system.
Have the car checked without delay by a
workshop. We recommend that you con-
tact an authorized Saab dealer.

239 Car care and technical information
Changing a wheel
WARNING
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
flat tire. If it is used for anything else, you
or others could be badly injured or killed if
the vehicle slips off the jack. Use the jack
provided with your vehicle only for chang-
ing a flat tire.
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire. To
help prevent the vehicle from moving:
1 Set the parking brake firmly.
2 If you have an automatic transmis-
sion, put the shift lever in PARK (P).
For a manual transmission, leave the
car in gear (1st or REVERSE (R)).
3 Turn off the engine and do not restart
while the vehicle is raised.
4 Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle won't
move, you should put blocks at the front
and rear of the tire farthest away from the
one being changed. That would be the
tire, on the other side, at the opposite end
of the vehicle.
 The car jack is designed solely for use
in changing a wheel or fitting snow
chains. It must not be used to sup-
port the car during repair work or
servicing.
Never crawl under a car that is
supported only by a jack.
 Raising your vehicle too high or with
the jack improperly positioned can
damage the vehicle and even make
the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to
fit the jack lift head into the proper
location before raising the vehicle, and
raise the vehicle only far enough off
the ground so there is enough room
for the spare tire to fit (no more than
25 mm or 1 inch clearance between
the ground and the bottom of the tire).
 Switch on the hazard warning lights if
the car is on a road.
 The jack should be stored correctly
under the carpeting in the trunk. If it
lies loose in the car, it could thrown for-
ward and cause personal injury in the
event of a crash or if the car rolls over.
 Grit, salt and rust can clog the inner
threads of the wheel bolts if the car has
been driven for several years exclu-
sively with alloy wheels.
If steel wheels are being installed, the
bolt hole threads in the brake hubs
should be cleaned before the thinner
steel wheels are fitted. It may other-
wise not be possible to achieve the
correct clamping force, despite tight-
ening the wheel bolts to the correct
torque.

240 Car care and technical informationTo jack up the car, apply the jack to one of
the special jacking points under the sills.
If a floor jack is used, it can be applied to the
standard jacking points used by the dealer.
A floor jack can lift both front wheels or both
rear wheels off the ground simultaneously.
A jack stand must then be applied under-
neath the front of the engine subframe (at
the fixing point for the towrope-attachment
eye) or to the rear towrope-attachment eye
(or under the trailer hitch, if fitted).1 Put the car in 1st gear (automatic trans-
mission: move selector to the P position)
and apply the parking brake.2 Wind the jack up to a suitable height
before placing it under the recess in the
sill.
Make sure that the jack fully engages
the recess in the sill and that the base of
the jack is steady and flat on the ground.
3 Remove the wheel cover (where appli-
cable).
Loosen the wheel bolts by half a turn.
4 Wind the jack to raise the wheel clear of
the ground. Remove the wheel bolts and
lift off the wheel.
5 Clean any rust or dirt from the contact
surfaces between the wheel and brake
disc. Do not wipe away the grease in the
hub.
6 Fit the wheel and screw in the bolts in the
sequence shown (opposite pairs) - see
page 242.

indicated on the body.Position for jack

245 Car care and technical information
Waxing and polishingOther than in exceptional cases, do not use
abrasive polishes containing a cutting agent
on a new car. Always wash the car thor-
oughly before waxing or polishing.Engine compartmentClean the engine compartment using an
engine detergent and rinse with hot water.
Cover the headlights. Do not use high-pres-
sure washer. Avoid spraying the hood liner,
as this can become heavy and hang down
and touch the engine when the hood is
closed.
Do not use gasoline as a cleaning agent or
solvent when carrying out repairs or mainte-
nance. Saab recommends the use of envi-
ronmentally safe degreasing agents.
Touching up the paintDamaged paintwork should be treated as
soon as it is discovered: the longer it is left,
the greater the risk of corrosion. The
anti-perforation warranty does not cover
corrosion resulting from untreated defects.
Paintwork damage sustained in a crash is
usually extensive and can only be properly
restored by professionals.
However, you can repair small scratches
and stone-chip damage yourself. The nec-
essary tools and materials, such as primer,
touch-up paint and brushes, are available
from your Saab dealer.
In the case of minor flaws in the paintwork,
where the metal has not been exposed and
an undamaged layer of paint remains,
touch-up paint can usually be applied
directly, after any dirt has been scraped
away using a pointed knife.If corrosion has already set in, e.g. as a
result of stone-chip damage, use a pointed
knife to scrape off all surface rust. If possi-
ble, the damaged area should be taken
back to the bare metal. The metal should
then be primed with two thin coats of primer
applied by brush.
After the primer has dried, apply several thin
layers of topcoat enamel until the surface of
the repaired area is flush with the surround-
ing paintwork.
Stir both primer and touch-up enamel thor-
oughly before use and allow each coat to
dry before applying the next.
