2003 SAAB 9-3 heating

136 Starting and drivingLock-upThe transmission’s torque converter has a
lock-up function. This can lock the torque
converter in 3rd, 4th and 5th gears, thus
reducing the engine speed and fuel con-
sumption.Kick-downWhen the accelerator is pressed down fully,
a down change is made to optimize acceler-
ation, e.g. for overtaking.
Following this, the next higher gear will be
selected at the optimum engine speed,
unless you ease off the accelerator before
reaching this. Kick-down works in manual
mode in 4th and 5th gears if the engine
speed is lower than 2,000 rpm.
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 164.
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 to 4th gear. If you desire more
powerful engine braking, manually select a
lower gear (see page 139).
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!

142 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 54).
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 malfunction.
Contact Saab dealer.

155 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 179. 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, carburettor
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-
rettor 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.Winter tires, particularly studded tires,
generally 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.
Remember 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.

159 Starting and driving
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. As
regards 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!
