heating SAAB 9-3 2004 Owner's Manual

175 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 199.
 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, carburetor
spirit 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 carbu-
retor spirit 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.
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 (snow) tires be fitted.
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.

179 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 reducedThe 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.
When continuing your journey, manually
select a low gear in which the engine speed
is about 3,500 rpm until the incline eases
(see page 158).NOTICE Use only a genuine Saab trailer hitch,
since other models can damage the
car’s bodywork and electrical system.
 Consult 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.

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!

180 Starting and drivingRecommendations 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 1, 2, or 3) to spare the brakes
when you are driving on a long or steep
downhill slope.
Overheating can cause the brakes to
fade!

231 Car care
TiresYour new vehicle comes with high-quality
tires made by a leading tire manufacturer. If
you ever have qestions about your tire war-
ranty and where to obtain service, see your
Saab Warranty and Service Record Booklet
for details.
Inflation - Tire PressureThe Tire-Loading Information label, which is
on the inside of the trunk lid, shows the cor-
rect inflation pressures for your tires when
they’re cold. “Cold” means your vehicle has
been sitting for at least three hours or driven
no more than 1 mile (1.6 km).Notice:
Don’t let anyone tell you that
underinflation or overinflation is all
right. It’s not. If your tires don’t have
enough air (underinflation), you can get
the following:
 Too much flexing
 Too much heat
 Tire overloading
 Bad wear
 Bad handling
 Bad fuel economy
If your tires have too much air (overinfla-
tion), you can get the following:
 Unusual wear
 Bad handling
 Rough ride
 Needless damage from road hazardsAdjust the tire pressure to match the current
load and speed of the car (see page 277).
The stated tire pressures apply to cold tires,
i.e. tires that are the same temperature as
the outside air temperature. Tire pressure
increases as the tires become warm (e.g.
during highway driving) by approximately
0.3 bar (4 psi). When the temperature of the
tires changes by 50°F (10°C), the tire pres-
sure will change 0.1 bar (2 psi).
Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
WARNING
Poor maintained and improperly uswed
tires are dangerous.
 Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out and
a serious accident. See “Loading Your
Vehicle” on page 240.
 Underinflated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked
when your tires are cold.
 Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact – such as when you hit a
pothole. Keep tires at the recom-
mended pressure.
 Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.
