156 Starting and driving

Fuel (Gasoline Engine)

Use regular unleaded gasoline rated at 87

octane or higher. Use of gasoline with an

octane rating lower than 87 can result in

severe engine damage. Damage caused by

incorrect fuel being used is not covered

under the terms of the New Car Warranty

and will be the responsibility of the owner. It

is recommended that the gasoline meet

specifications which were developed by the

American Automobile Manufacturers Asso-

ciation (AAMA) and endorsed by the Cana-

dian Motor Vehicle Manufacturers Associa-

tion for better vehicle performance and

engine protection. Gasolines meeting the

AAMA specification could provide improved

driveability and emission control system

performance compared to other gasolines.

Be sure the posted octane is at least 87. If

the octane is less than 87, you may get a

heavy knocking noise when you drive. If it’s

bad enough, it can damage your engine. If

you’re using fuel rated at 87 octane or

higher and you hear heavy knocking, your

engine needs service. But don’t worry if you

hear a little pinging noise when you’re accel-

erating or driving up a hill. That’s normal,

and you don’t have to buy a higher octane

fuel to get rid of pinging. It’s the heavy, con-

stant knock that means you have a problem.

NOTICE

Higher concentrations of methanol than

listed above, or the use of methanol-

blended gasoline without suitable

co-solvents and corrosion inhibitors,

can damage your car’s fuel system,

leading to the need for repairs which are

not covered by Saab’s product warranty.

NOTICE

The engine control module (ECM) mon-

itoring the engine parameters also

stores fault codes.

Under certain circumstances, this may

cause constant illumination of the

”Engine malfunction (CHECK

ENGINE)” lamp , thus indicating a

fault that must be checked by your Saab

dealer, see page 57.

NOTE: always observe the following two

measures:

• Make sure that the fuel filler cap is

screwed on correctly before the

engine is started. Screw on the fuel

filler cap until you hear 3 distinct

clicks.

• Avoid driving with the fuel low level

indicator illuminated. The symbol

illuminates when less than approxi-

mately 2 gallons (8 litres) of fuel

remains in the tank.

In Canada, look for the

”Auto Makers’ Choice” label

on the fuel pump.
