Manual transmission

Check and top up the oil in accordance with

the service program.

Automatic transmission

Check and top up the oil in accordance with

the service program.

Coolant

There is an overpressure in the cooling sys-

tem. Coolant temperatures can sometimes

exceed 212° F (100° C).

If 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.

Coolants of a different brand could damage

the engine or cooling system. We therefore

recommend strict use of coolants that have

been approved by Saab.

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.

NOTICE

If 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.
