156 Starting and driving
• Have the car serviced regularly in accor-
dance with the service program.
• Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to a workshop. We
recommend that you contact a Saab
dealer.
• If the engine fails to start (in severe cold
or if the battery is flat), the car can be
bump started (manual transmission only)
or started using jump leads to a donor
battery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
it to idle for up to 5 minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
switch off the engine to avoid serious
damage to the catalytic converter. We
recommend that you contact a Saab
dealer for advice.
• Never park the car on dry grass or other
combustible material. The catalytic
converter gets very hot and could there-
fore start a fire.
• Never drive off if the engine is misfiring.
• If you bump start the car when the engine
is already at normal working temperature,
the engine must start to run on all cylin-
ders. Abort bump starting if the engine
fails to start immediately.
Failure to strictly follow these instructions
can result in damage to the catalytic con-
verter and associated components, and
could represent a breach of the warranty
conditions.
NOTICE
If the car runs out of gas, air may be drawn
in with the fuel, which, in turn, can cause
the catalytic converter to be damaged by
overheating.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, to ensure
adequate cooling, air must be blown into
the engine compartment and under the
car at a rate equivalent to the ram-air
effect that would obtain at the corre-
sponding road speed.
