173 Starting and driving
Driving in hot weather Always check the coolant level before
starting a journey. When the engine is
cold, the coolant must not be above the
KALT/COLD mark on the expansion tank.
 At the end of a journey, if the engine has
worked hard, allow it to idle for two or
three minutes before switching it off.
If the needle on the temperature gauge
enters the red zone:
1 Bring the car to a standstill but leave the
engine running. Do not remove the cap
on the expansion tank even if the tank is
empty. The engine temperature should
decrease. If the temperature continues
to rise with the engine idling, the engine
must be switched off. 2 If the engine is idling and the needle on
the temperature gauge falls, wait until a
normal temperature is shown (about in
the middle of the scale) before switching
off the engine. If the coolant needs top-
ping up, unscrew the cap on expansion
tank carefully.
Top up, as necessary, ideally with a
50/50 mixture of coolant and water. Use
a Saab-approved coolant. If only water
is available, use that, but remember to
have the coolant mixture checked as
soon as possible.
3 As soon as possible, have the cooling
system checked by an authorized Saab
dealer.
Towing a trailerTrailer hitch attachment Trailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs (1588 kg),

tor provided in the trailer hitch kit.
Saab recommends:
 Use a Saab original hitch kit attachment
which is designed and tested by Saab.

hitch kit for your car.
WARNING
Always undo the expansion tank filler cap
carefully, releasing the pressure and any
vapor before removing the cap com-
pletely.
NOTEUse only a genuine Saab trailer hitch and
wiring, since other wiring methods can
cause expensive damage to the car’s
body and electrical system.
Consult an authorized Saab dealer for
guidance on how to connect the trailer
hitch electrical system.
