2007 SAAB 9-3 Owners Manual

185 Starting and driving
Driving in cold weatherIn cold weather, special attention should be
paid to the following:
Before driving off, make sure that the
wiper blades have not frozen to the wind-
shield.
Remove any snow from the heating
system air intakes between the hood and
the windshield.
If necessary, inject oil into the locks to
prevent them from freezing. Use molyb-
denum-sulphide oil (MoS
2). If the locks
freeze, exercise care when unlocking the
car (manual unlocking) to avoid breaking
the key. Warm up the key or use a de-icer.
It is particularly important when the roads
are slippery that the brakes and tires are
in good condition.
For how to check the level of antifreeze in
the engine coolant, see page 209. Add gasoline anti-freeze when refueling
several times before the onset of winter.
This will prevent condensation water in
the fuel tank from freezing and causing
interruptions in the fuel supply. The likeli-
hood of condensation is lowest when the
fuel tank is full.
If the car is parked outside and the
temperature is below zero, gasoline anti-
freeze is of little use as it cannot remove
water that has already frozen. Park the
car in a warm place so that any ice that
may have built up melts, then add gaso-
line anti-freeze when refueling.
Condensation is caused by temperature
fluctuations, either in the outside temper-
ature alone or when the car is alternately
parked outdoors and in a garage.
Convertible: Avoid operating the soft top
at temperatures below 23°F (–5°C). The car is equipped with tires designed to
provide optimum grip on both wet and dry
roads, although this has been achieved at
the expense of somewhat reduced grip on
snow and ice. For regular driving on snow
and ice, we therefore recommend that
winter tires be fitted. However, winter tires
achieve this extra grip at the expense of
grip on bare road surfaces.
Winter tires, particularly studded tires, gen-
erally make driving safer on snow and ice.
Acquaint yourself with the legal provi-
sions governing the use of different
types of winter tires and snow chains.
Studded tires are not allowed in some
countries. If winter tires are fitted, the same
type must be fitted to all four wheels. Your
Saab dealer will be pleased to advise you on
the best tires for your car.

186 Starting and drivingRemember that tires age: it may therefore
be necessary to change winter tires before
they reach the legal wear limit, as they grad-
ually lose their friction properties with age.
If you get into a front wheel skid and the car
has a manual transmission, the best
response is to freewheel, which means
declutching so that the wheels neither drive
nor brake, and to cautiously steer in the
desired direction.
If the car has automatic transmission, ease
off the accelerator slightly and steer cau-
tiously in the desired direction.
If you get into a rear wheel skid, steer in the
same direction as the movement of the rear
of the car.
Driving with tire chains3Snow chains must only be fitted to the wheel
and tire dimensions that Saab recommends
in "Technical data" on page 279.
We recommend that you contact a Saab
dealer regarding approved tire chains. See
also page 248.
WARNING
Do not drive at speeds above 30 mph
(50 km/h) when tire chains are fitted.
Tire chains can reduce directional
stability.
Do not fit tire chains to the car’s rear
wheels.
NOTICE Check the links frequently for wear.
Check that the chains do not foul the
wheel arch liner at full lock.
Refer to the "Technical data" section
on page 279, for information on wheel
and tire dimensions approved for the
fitting of tire chains.

187 Starting and driving
Driving in hot climatesAlways check the coolant level before start-
ing a journey. When the engine is cold, the
coolant must not lie above the KALT/COLD
mark on the expansion tank (boundary
between the upper and lower sections of the
tank).
At the end of a journey, allow the engine to
idle for 2–3 minutes before switching it off.
If the needle on the temperature gauge
enters the red zone, the following message
will be shown on the SID:
1 Stop the car but do not switch off the
engine. Do not remove the cap on the
cooling system expansion tank, even if
the tank is empty. The engine tempera-
ture 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 to be
topped up, carefully unscrew the
expansion tank cap.
Fill as required with a mixture of 50 %
antifreeze and 50 % clean water. Use an
antifreeze approved by Saab.
3 Have the car’s cooling system checked.
We recommend that you contact a Saab
dealer. Hot engine. Make a
safe stop. Idle engine.
WARNING
Exercise care when opening the hood
if the engine is overheated. Never
remove the expansion tank cap
completely when the engine is hot.
The cooling system is pressurized -
hot coolant and vapour can escape.
These can cause injury to your eyes
and burns. Open the cap slowly to
release the pressure before removing
it.

188 Starting and drivingTowing a trailer3Make sure you are familiar with the legal
requirements regarding speed limits for
towing, maximum trailer weights, trailer
braking requirements, and also any spe-
cial driving licence provisions.
Trailer hitch attachment3Trailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs (1588 kg),
with trailer brakes.
An electrical connection3 for the towbar
and an electrical unit are provided in the
electrical centre on the left-hand side of the
luggage compartment.
If the car has a 13-pin Saab genuine electri-
cal socket then it is possible to supply a
trailer/caravan with rear fog lights and
reversing lights. The caravan can also have
interior and exterior lighting even when the
car’s ignition is switched off. In which case,
remember not to load the battery for too
long so that it is discharged and pre-
vents the car from starting.
There is also access to power in the caravan
during a journey, the caravan battery can be
charged for example.
Also, if the car has SPA, this is deactivated
automatically if a trailer is hitched up and
correctly connected to the Saab genuine
trailer socket.
Saab recommendations:
Use a genuine Saab trailer hitch that is
designed and tested for your Saab.
Contact your Saab dealer for advice on
which trailer hitch is designed for your car.
WARNING
Do not drive with a trailer on inclines
steeper than 15 %. The load on the
drive (front) wheels will be so low that
the wheels can start to spin and
prevent further progress.
In addition, the car’s parking brake
may not always be sufficient to hold
the car and trailer securely, as the
wheels may start to slide.
Always apply the trailer’s parking
brake when unhitching it. There is
otherwise a risk of personal injury or
damage to the bumper should the
trailer start to roll.
When you hitch up the trailer be sure
to attach its safety chains to the holes
by the hitch.93_U S _M 07.book Page 188 W ednesday, April 12, 2006 9:30 AM

189 Starting and driving
Recommendations for cars with
automatic transmissionThe following driving time limits are based
on the capacity of the cooling system in hot
weather, i.e. approximately 86°F (+30°C).
The following driving time limits are based
on the capacity of the cooling system in hot
weather, i.e. approximately 104°F (+40°C).When negotiating long hills, bear the follow-
ing important considerations in mind.
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following steps are taken in order as the
temperature of the transmission increases:
Gear change pattern is altered
A/C compressor is switched off
Max. engine torque is reduced
The following message will be displayed on
the SID if the transmission fluid becomes
too hot:
If this message appears, stop the car as
soon as it is safe to do so and allow the
engine to idle until the message has gone
out. The selector lever should be in
position P.
NOTICE Only use a towbar that has been
approved for your car. We recom-
mend that you entrust towbar installa-
tion to an authorised Saab workshop,
which can also provide important
information such as trailer weight.
Your authorised Saab workshop has
information on how the towbar is to be
installed and whether other measures
must be undertaken that could affect
the cooling system or other equipment
We recommend that you contact a
Saab dealer for guidance on how to
connect a trailer hitch.
Exercise care when driving on uneven
roads or against the curb if the car is
heavily laden. This particularly applies
to cars with 17" wheels.

190 Starting and drivingWhen continuing your journey, manually
select a low gear in which the engine speed
is about 3,500 rpm until the incline eases
(see page 168).
Recommendations for cars with
manual transmissionRises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
When the needle is just outside the red
zone, the A/C compressor will be switched
off and, on certain engine variants, the max-
imum engine torque will be limited.
When continuing your journey, select a low
gear in which the engine speed is about
3,500 rpm until the incline eases.
Trailer hitch loadThe weight distribution on the trailer makes
a lot of difference to the handling properties
of the car and trailer combination. With a
two-wheel trailer, concentrate the load over
the wheels and keep it as low as possible.
The trailer should be loaded so that the load
on the towball is 110–165 lbs. (50–75 kg).
Note that this load must be included in the
total load for the car. If this now exceeds the
specified load capacity, the load in the trunk
may have to be reduced by the correspond-
ing amount.
WARNING
Remember to use engine-braking (selec-
tor position M1, M2, or M3) to spare the
brakes when you are driving on a long or
steep downhill slope.
Overheating can cause the brakes to
fade!

191 Starting and driving
Checks before drivingMake sure that the car and trailer are in
good working order. This is essential since
towing a trailer increases the strain on the
car.
Check and if necessary adjust the tire
pressure of the car and trailer.
Make sure all wheel bolts are properly
tightened.
Make sure that the equipment joining the
car and trailer is properly secured and
adjusted.
Make sure the trailer’s electrical cable is
properly connected and is not so long that
it drags along the ground. Also, make
sure the cable is not too short and risks
breaking when turning a corner.
Check all bulbs.
Check the car and trailer brakes.
Make sure that all items on or in the
camper or trailer are properly secured.
Make sure that the trailer’s jockey wheel
is raised and locked.
Check the distribution of the load so that
the car and trailer are well balanced.
Check that the rearview mirrors provide
the best possible rearward vision.
Make sure the trailer’s safety cable is
correctly attached.
Driving considerationsAlways take extra care when towing a
trailer, as the car’s handling will be different
and its braking performance reduced. The
trailer’s braking system and suspension
also have a considerable effect on these
characteristics. See also "Driving with a
load" on page 194.
Drive carefully:
descending hills
on uneven roads
over railway crossings
when meeting large vehicles
If the car has automatic transmission, select
gear M1 when ascending or descending
steep hills.
ReversingGet someone to help you keep an eye out
behind the trailer as the door mirrors do not
always provide sufficient rearward vision
when reversing.

192 Starting and drivingDriving with a roof rack
loadThe maximum permissible roof load is
220 lbs. (100 kg). Note that the roof load
must be included in the car’s maximum per-
missible payload and axle load.
Strong, sturdy roof carriers designed spe-
cially for your car are available from your
Saab dealer. Always secure roof loads
securely.
Fitting roof carriers3Sport Sedan and SportCombi without
roof rails
1 Open the four covers on the roof of the
car.
2 Insert a screw with washer into each roof
carrier foot. Fit a seal onto each screw.
3 The roof carriers are marked front and
back.
4 Bolt the roof carriers to the brackets in
the roof.
5 Check that the roof carriers are firmly
mounted.
WARNING
A roof load will affect the car’s center
of gravity and aerodynamics. Be
aware of this when cornering and driv-
ing in crosswinds.
Adjust your speed to the prevailing
conditions.
Due to higher aerodynamics drag, fuel
economy may suffer when driving with
a roof rack.
