Engine oilChecking the oil levelCheck the engine oil level regularly.
1 Park the car on a level ground.
2 Switch off the engine and wait for
2–5 minutes. The engine should be at
normal operating temperature.
3 Take the dipstick out and wipe it off with
a clean rag before carrying out the
check.
The level must not be below the MIN mark
on the dipstick, but nor should it be above
the MAX mark. Excess engine oil could
result in abnormal oil consumption.
The distance between the MIN and MAX
marks is equivalent to 1.0 qt (1.0 l).2.0 Turbo (210 hk): The engine oil level is
checked each time the engine is started. If
the oil level is low, the following message
appears on the SID:
f this occurs the oil level must be checked
first. If the level is too low then it must be
topped up.V6: The engine has an oil level sensor that
checks the oil level when the engine is
running. If the oil level drops too low, the
following message appears on the SID:
f this occurs the oil level must be checked
first. If the level is too low then it must be
topped up.NOTICEToo high oil level can damage the engine.

220 Car careMake sure you screw on the oil filler cap
properly after topping up the oil to avoid
running problems.
It is normal for an engine to consume a cer-
tain amount of oil. It is therefore often nec-
essary to top up the oil between services.
Check the engine oil level regularly.
During the Break-in Period (approx.
3,000 miles or 5,000 km) and when driving
at high speeds or with a trailer, the oil con-
sumption may be higher than normal.
Changing engine oil
Engine oil and oil filter should be changed
according to the service program.
For oil volumes and grades, refer to
page 298.
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 221).
4 Fill with new oil.
Run the engine to normal temperature and
check the oil level.
NOTICEChange of engine oil and oil filter may be
required more frequently if the car is
being used under certain conditions, see
page 289.
WARNING
 Prolonged and repeated exposure of
the skin to engine oil can cause seri-
ous skin disorders. Avoid prolonged
skin contact whenever possible.
 Used engine oil contains chemicals
that have caused cancer in laboratory
animals. Always protect your skin by
washing thoroughly with soap and
water.
 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.

the service program.
Automatic transmission
Check and top up the oil in accordance with
the service program.
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 45 % antifreeze and
anti-corrosion fluid. This ratio gives the best
cooling effect. Lower concentrations should
be avoided, in view of the corrosion risk.
Other brands of antifreeze can damage the
engine and cooling system.
Note:
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.
WARNING
To ensure reliable operation, only use
an air filter recommended by Saab
Automobile AB.
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.
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.

223 Car care
4-cyl engine: The expansion tank is trans-
parent to facilitate 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 anti-
freeze and clean water. We recommend
that you use a Saab-approved anti-freeze.
If the expansion tank is empty when coolant
is added, run the engine until warm so that
the thermostat opens. Top up the tank
again, as necessary.V6 engine: The expansion tank is not trans-
parent. The cap must be unscrewed so that
the coolant level can be checked. When the
cap is screwed off there are two level mark-
ings, MIN and MAX

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.
Top up with CHF 11S or CHF 202 power
steering fluid.

227 Car care
Always connect the positive (red) cable to
the battery’s positive (+) terminal, and the
negative (black) cable to the negative (-)
terminal of the battery. Always disconnect
both battery leads when boost charging the
battery.
A car with standard equipment specifica-
tions and a fully charged battery can be left
for up to 40 days and still have a sufficient
charge for starting. If extra equipment is fit-
ted, such as a mobile phone, the charge
may only be sufficient for about 15 days.NOTICE If boost charging never use anything
but a 12-volt charger, see page 208.
 Do not connect the battery termi-
nals, + and –, incorrectly.
 Serious damage can occur to the car’s
electrical system if a battery or alterna-
tor lead is disconnected while the
engine is running.
