SAAB 9-3 2006 Owners Manual

191 Starting and driving
If you stop the car with reverse gear
engaged, the sound pulse will stop after
2 seconds. The sound pulses will return if
you continue to reverse. If the car rolls for-
ward while reverse is engaged, the system
is silenced.
When the distance to the object is less
than 1 ft. (30 cm), a continuous tone will
be heard.
When an object is approximately 3 ft.
(90 cm) from the car, the sound pulses
change character markedly (frequency
increases). A distance of about 3 ft. (90 cm)
is suitable if you wish to load or unload the
trunk.
If the distance between an object and a
corner sensor does not change for
3 seconds, for example if you are reversing
alongside a wall, the system will switch to
monitoring straight back. The system indi-
cates if the distance to the wall decreases
again.
If a trailer is hitched up and correctly con-
nected to the trailer contact by the tow bar,
the system is automatically deactivated.Reversing alongside a wall
If the distance between an object and a
corner sensor does not change for
2 seconds, for example if you are reversing
alongside a wall, the system will switch to
monitoring straight back. The system indi-
cates if the distance to the wall decreases
again.Cars with trailer hitch
If the car has a trailer hitch and its wiring is
correctly connected to the car’s electrical
system, the Saab Parking Assistance auto-
matically compensates for the protrusion of
the tow bar.
If a camper or trailer is hitched up and the
trailer hitch wiring is correctly connected to
the car’s electrics, the system is automati-
cally deactivated.
You can temporarily deactivate the Saab
Parking Assistance as follows:
 Engage reverse and press the CLEAR
button on the SID control panel.
The system will be reactivated the next time
you engage reverse.
NOTICEThe sensors must be kept clean to func-
tion well. Ice, snow and dirt can affect
their sensitivity.
Large quantities of snow or dirt covering
the sensors can prevent the parking
assistance system from detecting any
objects.
Do not spray the sensors with a pressure
washer, as this can damage them.

193 Starting and driving
Economical drivingFactors affecting fuel
consumptionThe fuel consumption of a car is greatly
affected by driving conditions, climate, road
conditions, speed, driving technique, etc.Breaking-inFuel consumption may be somewhat
higher during the break-in period (the
first 3,000–4,000 miles (5,000–7,000 km)).Weather conditionsSummer temperatures give better fuel
economy than winter ones. The difference
can be as much as about 10%. Consump-
tion increases in cold weather because the
engine takes longer to reach its normal
operating temperature. The transmission
and wheel bearings also take longer to
warm up. Even distance affects consump-
tion: short journeys of 3–5 miles (5–8 km)
do not give the engine enough time to
reach its optimum temperature. Wind con-
ditions also have a marked effect on fuel
consumption.How to read the diagram:
If fuel consumption with the engine at
normal temperature is 28 mpg (10 l/
100 km), the actual fuel consumption
3 miles (5 km) after the engine has started
from cold will be:
– 23.5 mpg (12 l/100 km) at outside temp.
of 68°F (+20°C) (increase of 20%).
– 17.7 mpg (16 l/100 km) at outside temp.
of 32°F (0°C) (increase of 60%).
– 14 mpg (20 l/100 km) at outside temp.
of –4°F (–20°C) (increase of 100%).
It is clear from the diagram that both dis-
tance driven and outside temperature have
a significant impact on fuel consumption,
after a cold start.
If the car is normally driven on short jour-
neys, 3–5 miles (5–8 km), for example to
and from work, the average consumption
will be 60–80% above the normal level.
Driving techniques To obtain the best running economy, with
regard to fuel consumption and general
wear, the car must be serviced regularly.
 High speed, unnecessary acceleration,
frequent braking and much changing
down all give higher fuel consumption.
 Frequent gear changing in traffic, starting
in cold weather, the use of studded tires
and roof racks, and towing a camper all
increase fuel consumption.
 Do not warm up the engine while the car
is stationary.
If idling, the engine will take much longer
to reach its optimum temperature, and Percentage increase in fuel consumption
of engine starting from cold compared to
engine at normal temperature.

194 Starting and drivingengine wear is at its greatest during this
period. Drive off as soon as possible after
starting the engine and avoid high engine
speeds.
 Drive as smoothly and thoughtfully as
possible. Match your driving to the prevail-
ing traffic conditions.
 Driving in a low gear gives rise to higher
fuel consumption than driving in a high
gear because of the higher engine speed
for any given road speed. Always shift up
as soon as traffic conditions allow and
drive in the highest gear as much as
possible.
 Check the tire pressure once a month.
Incorrect tire pressure increases tire
wear. It is preferable for the tire pressure
to be slightly high than too low. Under-
pressure increases fuel consumption. Check the fuel consumption regularly.
Increased fuel consumption can indicate
that something is wrong and that the car
needs to be checked. We recommend
that you contact a Saab dealer.
Practical road tests have demonstrated that
substantial savings in fuel consumption can
be made if the above advice is followed.
Road conditionsWet roads increase fuel consumption, as do
unpaved roads and driving in hilly country
(the amount of fuel saved driving downhill is
less than the additional amount required to
climb the hill).
Engine block heater3The following are just some of the benefits
to the car and the environment of using an
engine block heater:
 Lower fuel consumption.
 Reduced wear on the engine.
 Inside of car warms up faster.
 Exhaust emissions substantially reduced
over short runs.
The engine heater is effective at outside
temperatures up to 60–70°F (+15–+20°C).
The warmer it is outside, the shorter the time
the engine heater needs to be connected.
Longer than 1.5 hours is unnecessary.
If the car is equipped with a removable,
electric cabin heater that is not in use, store
this in the trunk.
WARNING
Never switch off the engine while driving
as the effect of the brakes and power
steering will be greatly reduced.

195 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 222.
 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.

196 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 293.
We recommend that you contact a Saab
dealer regarding approved tire chains. See
also page 263.
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 293, for information on wheel
and tire dimensions approved for the
fitting of tire chains.

197 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.
Run engine on idle.
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.

198 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.
The Saab genuine electrical socket enables
a battery in the trailer on tow to be charged
while driving. 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.93U S M 06.book Page 198 Friday, February 18, 2005 1:15 PM

199 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 178).NOTICE We recommend you to use a genuine
Saab trailer hitch, since other models
can damage the car’s bodywork and
electrical system.
 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.

200 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!
