Changing engine oil
Engine oil and oil filter should be changed
according to the service program.
For oil volumes and grades, refer to "Tech-
nical data".
The oil should be drained when the engine
is warm. The car must stand on level
ground.
1 Unscrew the drain plug in the bottom of
the sump and leave the oil to drain into
a suitable receptacle for at least
10 minutes. Take care, as the oil may be
hot.
2 Refit the drain plug with a new washer.
3 Change the oil filter once the engine oil
has drained (see page 178).
4 Fill with new oil.
Run the engine to normal temperature and
check the oil level.
WARNING
 Prolonged and repeated exposure of
the skin to engine oil can cause seri-
ous skin disorders. The risk of cancer
cannot be ruled out.
 Avoid prolonged skin contact when-
ever possible. Wash the affected area
thoroughly with soap and water after
any contact.
 Keep oil out of reach of children.
 Do not touch the turbocharger or
exhaust manifold. These get very hot
when the engine has been running.
 Do not spill oil on hot parts of the
engine as this could cause a fire. Used
engine oil is particularly flammable.
 Protect the environment. Do not
dispose of oil into the ground or down
a drain. Dispose of all used oil and
oil filters at an appropriate disposal
facility.

179 Car care
CoolantIf the coolant level drops too low, the follow-
ing message appears on the SID:The properties of the coolant are retained
for the entire service life of the car. There-
fore, it is not necessary to change the cool-
ant.
The coolant contains 50 % antifreeze and
anti-corrosion fluid. This ratio gives the best
cooling effect. Lower concentrations should
be avoided, in view of the corrosion risk.
Other makes of antifreeze can damage the
engine and cooling system.The expansion tank is transparent to facili-
tate checking the coolant level.
When the engine is cold, the coolant must
not lie above the KALT/COLD mark on the
expansion tank (boundary between the
upper and lower sections of the tank, see
illustration).
Top up with a mixture of equal parts of
Saab-approved antifreeze and clean water.
If the expansion tank is empty when coolant
is added, run the engine to normal temper-
ature and top up again, as necessary.
WARNING
 Proceed with caution if the radiator is
boiling when you open the hood.
Never remove the expansion-tank
filler cap when the radiator is boiling.
 The cooling system is pressurized –
hot coolant and vapor can escape
when the filler cap is released. These
can cause injury to your eyes and
burns. Loosen the cap carefully, and
let the engine cool before removing
the cap.
 Exercise care when adding coolant.
Coolant on hot surfaces constitutes a
fire risk.
Coolant level low.
Refill.

180 Car careNote:
If incorrect coolant is used or added, the life-
time properties will be affected. Even if the
coolant is flushed from the system and
replaced with life-time coolant, life-time
properties are no longer retained and the
coolant must then be drained and replaced
at regular intervals.
Brake/clutch fluid and
brake padsCheckingBrake fluid should be changed according to
the service program. Refer to the Warranty
and Service Book.
The brake and clutch fluid reservoir is trans-
parent to facilitate checking of the fluid level.
The fluid level should lie between the MAX
and MIN marks.
Top up as necessary with DOT 4 brake
fluid. Do not use DOT 5 fluid.
Use only new brake fluid from a sealed
container.
The brake fluid level will fall somewhat as
the brake pads wear. The MAX level in the
reservoir corresponds to the amount of
brake fluid required with new brake pads. If
the fall in fluid level is moderate, due to
normal brake pad wear, topping up is not
necessary.If the brake fluid should require chang-
ing, this must be carried out at a Saab
dealer.
NOTICEIf the cooling system needs topping up,
mix the antifreeze with the appropriate
quantity of drinking water or distilled
water before adding it to the system.
If undiluted antifreeze is added, the
engine could still freeze and be damaged.
This is because the antifreeze will not mix
properly with the coolant before the ther-
mostat has opened to allow full circula-
tion.
WARNING
Brake fluid deteriorates as it becomes
old. Because it is hygroscopic, it absorbs
water from the air and, in time, could allow
vapor to form in the brake system, thus
reducing its performance. It is therefore
important that brake fluid be changed
regularly, as specified in the service
program.

181 Car care
The foot brake and parking brake are self-
adjusting.
It is not possible to detect, through abnormal
pedal or parking brake lever travel, whether
the brake pads are worn and need replac-
ing. It is therefore essential that brake pads
be checked regularly, as specified in the
service program.
Brake pads should only be changed at a
Saab dealer. To ensure optimum brake
performance, use only Saab genuine
brake pads.
Power steeringCheck the level of the power steering fluid in
the reservoir regularly, in accordance with
the service program.
The wheels should point directly forwards
during this check.
Clean round the cap before unscrewing it.
Wipe the dipstick. To check the level, screw
down the cap completely and then remove
it again.
The oil level should lie between the MAX
and MIN marks when the oil temperature is
about 68°F (+20°C). If the oil is colder, the
level will be lower, and at a higher tempera-
tures the level will be higher, both of which
are acceptable.
Top up with "CHF 11S power steering fluid".
NOTICEAvoid spilling brake fluid onto paintwork,
since it can cause the paint to bubble and
lift. If any brake fluid is spilled, the area
should be flushed with large quantities of
water as quickly as possible.
WARNING
Power steering fluid on hot engine
components constitutes a fire risk.

182 Car careBattery
Check the charge state and electrolyte level
of the battery regularly.If frequent short journeys are made, the
battery may need extra charging. This can
be done with a battery charger or by taking
the car for a long run.
If the battery is not being charge while the
engine is running, the following message
will appear on the SID:
Check the drive belt (see page 185). If the
belt is damaged, the engine may overheat,
the battery may not be charged and the A/C
compressor may not work.
WARNING
 When working on the battery, highly
explosive gas can build up. A spark
could ignite this gas that collects
around the battery.
Therefore, always avoid sparks and
open flames in the vicinity of the
battery.
 The battery contains corrosive sulphu-
ric acid. Always wear a face mask or
goggles when working on the battery.
 If battery acid gets into the eyes or
splashes onto skin or clothing, wash
the affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.
NOTICEA discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from sub-zero temperatures.
Battery not charging.
Make a safe stop.
Contact Saab dealer.

188 Car careChanging bulbsAutochecking of lightsThe bulbs that are most important from the point of view of traffic
safety are monitored by the car’s electrical system. If one of these
bulbs should fail, a message will be displayed on the SID.
Example of SID message:
The following bulbs are not checked: parking lights, front fog lights,
reversing lights, license plate lighting, side marker lights and side
direction indicators.If a brake light bulb fails
If a brake light bulb fails, the adjacent tail light will act as a brake light
to ensure traffic safety. Change the broken bulb when possible.
All rear light bulbs are of the same type and rated 21 W, with the
exception of the license plate lighting which is rated 5 W.
Wrong bulb fitted
If a dipped or main beam bulb of too high a rating is fitted, a bulb
failure message will be shown on the SID (a too high wattage bulb
can damage the reflector).
If the following message is displayed but the bulb shines, it is most
likely that an incorrect bulb has been fitted.
Note:
When changing bulbs, fit the same type of bulb (e.g. Long-Life)
as that removed.
Headlight aiming, page 226.
WARNING
Before changing a bulb in the engine bay, switch off the engine
to avoid the danger of fingers and hands being injured by moving
parts.
The radiator fan can cut in even when the engine is switched off.NOTICESwitch off the ignition before changing a bulb, to avoid possible
short-circuiting.

Fuses
The fuses are housed in three fuse panels:
one behind a hatch on the left-hand end of
the fascia, one in the engine bay (additional
small unit in front of battery) and one on the
left-hand side of the trunk. There is space
for spare fuses in the hatch on the left-hand
end of the fascia.
To check if a fuse has blown, first remove it
from the panel. If the filament is broken, the
fuse has blown.
WARNING
To avoid the risk of short-circuiting and/or
fire breaking out in the electrical system,
the following should be heeded:
 Always consult an Saab dealer before
modifying or adding any electrical
equipment. Failure to do so can result
in the electrical system being
damaged.
 Never replace a fuse with one having
a higher rating than specified (see
page 201). The color of the fuse indi-
cates its amperage.
 If the same fuse blows repeatedly,
have the electrical system checked by
an Saab dealer.
 If a MAXI fuse blows, it means that
there is a major fault in the electrical
system. Have the car checked without
delay by an Saab dealer.

226 Car careHeadlight aimingThe vehicle has a visual optical headlight
aiming system equipped with vertical
aiming device. The aim has been preset at
the factory and should normally not need
further adjustments.
If your headlights are damaged in a crash,
the headlight aim may be affected. If you
believe your headlights need to be re-
aimed, we recommend that you take it to
your Saab dealer for service. However, it is
possible for you to re-aim your headlights as
described in the following procedure.To check the aim, the vehicle should be
properly prepared as follows:
 The vehicle shall be placed so that the
headlights are 25 ft (7.6 m) from a light
colored wall or other flat surface. The
aiming area should be darkened, this will
improve your ability to see the beam of the
low beam headlight being aimed.
An optical headlamp aimer can also be
used and will than replace the wall.
 The vehicle must have all four wheels on
a perfectly level surface which is level all
the way to the wall or other flat surface.
 The vehicle should be placed so it is per-
pendicular to the wall or other flat surface.
 The vehicle should be unloaded and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat.  The vehicle should be fully assembled
and all other work stopped while headlight
aiming is being done.
 The vehicle should not have any snow, ice
or mud attached to it.
 Tires should be inflated to the prescribed
pressure.
 Close all doors.
 Rock the vehicle to stabilize the suspen-
sion.
Headlight aiming is done with the vehicle
low beam lamps. The high beam lamps will
be correctly aimed if the low beam lamps
are aimed properly.
WARNING
Before checking/adjusting the headlight
aiming, 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.NOTICETo make sure that your headlights are
aimed properly read all instructions
before beginning. Failure to follow these
instructions could cause damage to
headlight parts or a not correctly aimed
headlight.

230 Maintenance and owner assistanceMaintenance scheduleThe Maintenance Schedule prescribes a
service program to the purchaser/operator
of a Saab that is reasonable and necessary
to ensure the proper emission control sys-
tems function, safety and reliability of the
Saab automobile in normal use. Additional
maintenance is recommended for specific
components when the car is operated under
certain severe conditions. Proper mainte-
nance is always a good practice!
Authorized Saab dealers are equipped and
trained to meet your Saab’s service needs.
They regularly receive up-to-date Saab ser-
vice manuals and parts and technical ser-
vice bulletins from Saab and are able,
through their franchise agreement, to attend
Saab service schools, obtain Saab special
tools and technical assistance and pur-
chase original equipment service and
replacement parts.
Today’s complex automobiles should only
be entrusted to the most knowledgeable
service professionals. A Saab dealer is your
best choice.
SERVICE INTERVALSThe maintenance schedule begins with an
Inspection Service at 30 days. A time for
service message will illuminate on the Saab
Instrument Display (SID) when the car is
due for regular maintenance. There are twi
different messages that will appear:
TIME FOR INTERMEDIATE SERVICE
indicates that an oil/filter change is required
along with several inspections. This mes-
sage is set by the engine management
system which calculates service intervals
based on several factors including driving
habits, ambient temperature, number of
cold starts, mileage driven and elapsed time
since the last service. Based on this algo-
rithm, this message may appear at mileage
as low a 8,000 or as high as 15,000 miles.
If mileage accumulation does not occur, the
message will be set, and maintenance
required at a maximum of 2 years.
TIME FOR MAJOR SERVICE will be set
when additional maintenance is necessary,
such as air filter or spark plug replacement.
This message will appear at 30,000 mile
intervals. When either message is dis-
played, contact your Saab Dealer for a ser-
vice appointment.
Failure to perform scheduled maintenance
in a timely manner may result in serious
damage to key components or systems.
.NOTICEThe Check-up will be done by your Saab
dealer at no charge and should be done
as close as possible to the scheduled 30
days.
