161Starting and driving
2 Wait until the needle has dropped back
to indicate normal temperature (roughly
midway, in the white zone) before stop-
ping 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 Saab-approved coolant
and water. 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 trailer
Trailer hitch attachment
Trailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs. (1588 kg),
see also page 253.
Use only the electrical trailer hitch socket
provided in the trailer hitch kit.
Saab recommends:
• Use a Saab original hitch kit attachment
which is designed and tested by Saab.
• Consult your Saab dealer regarding the
appropriate hitch kit for your car.
WARNING
• Exercise care when opening the hood
if the engine is overheated. Never
remove the expansion tank cap com-
pletely when the engine is hot.
• The cooling system is pressurized -
hot coolant and vapor can escape.
These can cause injury to your eyes
and burns. Open the cap slowly to
release the pressure before
removing it.
WARNING
• When towing a trailer, do not attempt
to negotiate a hill having a gradient in
excess of 15 %. The weight distribu-
tion over the front wheels of the car will
be insufficient to prevent wheelspin,
making further progress impossible.
• In addition, the parking brake may not
always be able to hold the car and trai-
ler securely, with the result that the
wheels can start to slide downhill.
• Always apply the trailer’s handbrake
when unhitching it. There is otherwise
a risk of personal injury or damage to
the bumper should the trailer start to
roll.
NOTICE
Use 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.
