2007 SAAB 9-3 heating

165 Starting and driving
Driving in hilly country with a
heavy loadThe transmission fluid can overheat when
the gearbox is strained, for example, when
driving with a trailer on hilly roads. To avoid
the transmission fluid overheating, always
drive with the selector lever in the D posi-
tion. The adaptive gear change patterns are
then active.
High air temperatures or a faulty oil cooler
can also cause the transmission fluid to
overheat. Overheating reduces the service
life of the fluid.
TowingTowing of cars with automatic transmission,
see page 195.Descending hillsIf the speed of the car increases while
descending a steep hill, despite the acceler-
ator being released, the control module will
change down. If you desire more powerful
engine braking, manually select a lower
gear (see page 168).
Limp-homeIf the transmission malfunctions, the control
module will activate limp-home mode. Driv-
ability will be affected to varying degrees.
The following message is shown on the SID:
WARNING
Remember to use the braking effect of the
engine (1st, 2nd or 3rd gear) when you
are descending long or steep hills to
spare the brakes.
Overheating can cause the brakes to
fade!
NOTICEDo not tow a trailer if limp-home mode is
engaged.
Gearbox malfunction.
Limited performance.

171 Starting and driving
ABS brakesThe Antilock Braking System (ABS) modu-
lates the brake pressure to each wheel. The
pressure is automatically reduced just
before the wheel locks up and then
increases again to the point at which the
wheel is just about to lock. The wheel sen-
sors send information to the brake system’s
electronic control module for every 4 or so
inches (decimetre) that the car rolls. This
information is processed continuously to
ensure that the adjustment of the brake
pressure will be as exact as possible.
Adjustment takes place up to 12 times per
second.The brake system provides Electronic
Brakeforce Distribution (EBD). This distri-
butes the brake pressure between the front
and rear wheels, in such a way as to achieve
optimum braking performance irrespective
of the car’s speed or load.
The ABS has a built-in diagnostics function
which will switch on the ABS warning light
if a fault is detected in the system (see
page 82).
The following message will appear on the
SID (and corresponding symbol on main
instrument unit) if a fault is detected:
WARNING
It is prudent to try your brakes from
time to time, especially when driving in
heavy rain, through water collected on
the road, in snow, on a wet road
surface or in salty slush. In such condi-
tions, the brakes may take longer than
normal to take effect. To rectify this,
touch the brake pedal periodically to
dry the brakes out.
The same applies after the car has
been washed or when the weather is
very humid.
Avoid parking the car with wet brakes.
Before parking, and if the traffic condi-
tions allow, brake quite heavily so that
the brake discs and pads warm up and
dry.
The brakes are power assisted and it
should be kept in mind that the servo
unit only provides the power assis-
tance when the engine is running.
The brake pressure required when the
engine is off, (e.g. when the car is
being towed) is roughly four times the
normal pedal force required. The
pedal also feels hard and unrespon-
sive.
Overheating can cause the brakes to
fade!
WARNING
The additional safety afforded by the
ABS system is not designed to allow
drivers to drive faster but to make
normal driving safer.
To stop as quickly as possible, without
loss of directional stability, whether
the road surface is dry, wet or slippery,
press the brake pedal down hard
without letting up (do not pump the
pedal), declutching simulta-
neously, and steer the car to safety.
Antilock brake malfunc.

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.

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!

TiresYour new vehicle comes with high-quality
tires made by a leading tire manufacturer. If
you ever have questions about your tire
warranty and where to obtain service, see
your Saab Warranty and Service Record
Booklet for details.
Inflation - Tire PressureThe Tire-Loading Information label shows
the correct inflation pressures for your tires
when they’re cold. “Cold” means your vehi-
cle 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 292).
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
4 psi (28 kPa). When the temperature of the
tires changes by 50°F (10°C), the tire pres-
sure will change 2 psi (14 kPa).
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 used
tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
friction. You could have an blow-out
and a serious accident. See “” on
page 251.
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.93_U S _M 07.book Page 241 W ednesday, April 12, 2006 9:30 AM
