or does not go out after the engine starts,
an emission control system malfunction
has been detected.
You should have your vehicle checked by
an authorized Saab dealer immediately.NOTEThis light also comes on when the fuelfiller cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator lamp coming on
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure nothing is interfering
with the sealing of the cap. Tightening the
cap will not make the CHECK ENGINE
warning light turn off immediately. It may
take several driving trips. If the light does
not go out, take your vehicle to your au-
thorized Saab dealer immediately.

gine misfire condition has been detected

sion control system, you should do the fol-
lowing.

ble.

sible.

dition but the light remains on, contact
your nearest Saab dealer immediately.Oil pressure warning

not go out after the engine starts, stop the
engine at the first safe opportunity and
check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil
is at the proper level but the light remains

cle’s warranty.

Maintenance and service
Spark plugsIt may be difficult to replace the spark
plugs. It is recommended that you have
the spark plugs replaced by your Saab
dealer.
The spark plugs should be replaced ac-
cording to the maintenance schedule in
the “Saab Warranty and Service Record
Booklet”.
Recommended spark plugsNon-turbo models:
FR5AP-11 (NGK)
Turbo models:
ILFR6B (NGK)
Drive belts1) Power steering pump pulley
2) Air conditioner compressor pulley
3) Crank pulleyThe alternator, power steering pump, and
air conditioner compressor depend on
drive belts. Satisfactory performance re-
quires that belt tension be correct.
To check belt tension, place a straight-
edge (ruler) across two adjacent pulleys
and apply a force of 22 lbs (98 N, 10 kg)
midway between the pulleys by using a
spring scale. Belt deflection should be the
amount specified. If a belt is loose,
cracked, or worn, contact your Saab deal-
er. When disconnecting the spark
plug cables, always grasp the
spark plug cap, not the cables.
Make sure the cables are replaced
in the correct order.
