service SAAB 9-3 2008 Owner's Manual

158 Starting and drivingHave the car serviced regularly in accor-
dance with the service program.
Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to a workshop. We
recommend that you contact a Saab
dealer.
If the engine fails to start (in severe cold or
if the battery is flat), the car can be bump
started (manual transmission only) or
started using jump leads to a donor
battery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
it to idle for up to 5 minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
switch off the engine to avoid serious
damage to the catalytic converter. We
recommend that you contact a Saab
dealer for advice.Never park the car on dry grass or other
combustible material. The catalytic
converter gets very hot and could there-
fore start a fire.
Never drive off if the engine is misfiring.
If you bump start the car when the engine
is already at normal working temperature,
the engine must start to run on all cylin-
ders. Abort bump starting if the engine
fails to start immediately.
Failure to strictly follow these instructions
can result in damage to the catalytic con-
verter and associated components, and
could represent a breach of the warranty
conditions.
NOTEIf the car runs out of gas, air may be drawn
in with the fuel, which, in turn, can cause
the catalytic converter to be damaged by
overheating.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, to ensure
adequate cooling, air must be blown into
the engine compartment and under the
car at a rate equivalent to the ram-air
effect that would obtain at the corre-
sponding road speed.

Refer to page 187 for information regarding
gasoline anti-freeze.
The fuel door has a built in filler cap holder
slot located on the fuel door. Slide the white
ring on the cap into the slot.
Notice: If you need a new fuel cap, be sure
to get the right type. Your dealer can get one
for you. If you get the wrong type, it may not
fit properly.
Filling a portable fuel container Fuel (Gasoline Engine)
Fuel
Use of the recommended fuel is an impor-
tant part of the proper maintenance of your
vehicle.
For optimum performance Saab recom-
mends:
Gasoline engines – AON 90.
Gasoline Octane
Use regular unleaded gasoline with a
posted octane of 87 or higher. If the octane
is less than 87, you may get a heavy knock-
ing noise when you drive. If this occurs, use
a gasoline rated at 87 octane or higher as
soon as possible. Otherwise, you might
damage your engine. A little pinging noise
when you accelerate or drive uphill is con-
sidered normal. This does not indicate a
problem exists or that a higher-octane fuel
is necessary. If you are using 87 octane or
higher-octane fuel and hear heavy knock-
ing, your engine needs service.
WARNING
Never fill a portable fuel container while it
is in your vehicle. Static electricity dis-
charge from the container can ignite the
gasoline vapor. You can be badly burned
and your vehicle damaged if this occurs.
To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
Do not fill a container while it is inside
a vehicle, in a vehicle’s trunk, pickup
bed or on any surface other than the
ground.
Bring the fill nozzle in contact with the
inside of the fill opening before operat-
ing the nozzle. Contact should be
maintained until the filling is complete.
Do not smoke while pumping gaso-
line.
When refueling, hang the fuel cap inside
the fuel door93_US_M08.book Page 161 Friday, May 11, 2007 11:37 AM

163 Starting and driving
gasoline whether the fuel contains MMT.
Saab does not recommend the use of such
gasolines.
Fuels containing MMT can reduce the life of
spark plugs and the performance of the
emission control system may be affected.
The malfunction indicator lamp may turn on.
If this occurs, return to your authorized Saab
dealer for service.
Fuels in Foreign Countries
If you plan on driving in another country out-
side the United States or Canada, the
proper fuel may be hard to find. Never use
leaded gasoline or any other fuel not recom-
mended in the previous text on fuel. Costly
repairs caused by use of improper fuel
would not be covered by your warranty.
To check the fuel availability, ask an auto
club, or contact a major oil company that
does business in the country where you will
be driving.
Engine Break-in PeriodPistons, cylinder bores and bearings need
time to obtain uniform, wear-resistant
surfaces.
If a new engine is driven too hard, this grad-
ual process of bedding-in will not be possi-
ble and the life of the engine will be short-
ened.
During the first 1,200 miles (2,000 km),
do not exceed 5,000 rpm.
In addition, refrain from driving the car at full
throttle, other than for brief instances,
during the first 1,800 miles (3,000 km).
Wearing in new brake padsNew brake pads take time to bed in, about
90 miles (150 km) if the car is driven largely
under stop-and-go conditions or about
300 miles (500 km) of highway driving.
To extend the useful life of the pads, avoid
hard braking as much as possible.

Sport mode3
33 3
Sport mode is selected using the
button, while the word SPORT illuminates
on the SID . Changing up occurs later
and changing down occurs earlier at the
same accelerator pedal position.
Sport mode will be deselected if:
The Sport button is depressed again
the engine is switched off.
Lock-upThe transmission’s torque converter has a
lock-up function. This can lock the torque
converter, thus reducing the engine speed
and fuel consumption.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.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 197.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 170).
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!

173 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 sur-
face 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.

175 Starting and driving
Traction Control
System (TCS)Anti-spin systemHow the system worksThe Traction Control System (TCS) is
designed to prevent wheelspin. This
enables the car to achieve the best possible
grip and, hence, maximum tractive effort,
together with greater stability.The TCS uses information from the ABS
wheel sensors to detect when the front (driv-
ing) wheels are rotating faster then the rear
wheels.
If the two front wheels are rotating faster
than the rear wheels, the torque from the
engine is reduced to eliminate the differ-
ence.
The process continues until all the wheels
are rotating at the same speed.
The advantages of the TCS become most
apparent when the cohesion between the
front wheels and the road surface is so low
that one or both of the wheels would lose
their grip were the car not equipped with the
TCS, e.g.:
When the car is pulling away or accelerat-
ing with the front wheels on different
surfaces (e.g. one slippery and one dry),
the TCS functions like an electronic differ-
ential lock, making sure that both wheels
rotate at the same speed. The system
also functions when the car is reversing.
When cornering, if the inside front wheel
rotates faster than the other wheels.
TCS OFF
lights up if:
the system has been switched off
manually. It cannot be switched off if the
car is travelling faster than 35 mph
(60 km/h).
there is a fault in the ABS system
a fault has been detected and the system
has therefore been switched off and at the
same time the following message is
shown on the SID:
WARNING
When driving normally, the TCS system
helps to improve the car’s stability,
maneuverability and traction under slip-
pery road and extreme driving conditions.
The TCS must not be regarded as a
system to enable the driver to maintain
higher speeds. The same precautions
must be adopted as normal for safe cor-
nering and driving on slippery roads.
Traction control failure.

185 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 techniquesTo 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 Percentage increase in fuel consumption
of engine starting from cold compared to
engine at normal temperature.

201 Starting and driving
4 Open the hood and locate the battery.
Find the positive (+) and negative (–) termi-
nals on the battery.5 Check that the jumper cables do not
have loose or missing insulation. If they
do, you could get a shock and also the
vehicles could be damaged.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) and
negative (–) will go to negative (–). Do
not connect (+) to (–) or you will get a
short that could injure you or would
damage the battery and maybe other
parts as well.
6 Connect the red positive (+) cable to the
positive (+) terminal of the vehicle with
the discharged battery.7 Do not let the other end touch metal.
Connect it to the positive (+) terminal of
the good battery. Use a remote positive
(+) terminal if the vehicle has one.
8 Now connect the negative (–) cable to
the good battery’s negative terminal.
9 Attach the cable to the discharged
battery’s negative terminal.
10 Start the vehicle with the good battery
and run the engine for a while.
11 Try to start the vehicle with the
discharged battery. If it does not start
after a few tries, it probably needs
service.
Note. If the current in the low battery is
too low it might be necessary to wait
several minutes with the cables
connected before you can start the
engine with the low battery.
12 Remove the cables in reverse order to
prevent electrical shorting. Take care
that they do not touch each other or any
other metal.NOTEIf you leave your radio on, it could be
badly damaged. The repairs would not be
covered by your warranty.
WARNING
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
WARNING
Using a match or flame of any kind near a
battery can cause battery gas to explode.
You can suffer burns or be blinded. Use a
flashlight if you need more light.
Be sure the electrolyte in the battery is not
frozen. Discharged batteries will freeze.
When connecting jumper cables to a
frozen battery, gas from the chemical
reaction inside the battery can build up
under the ice and cause an explosion.
Battery fluid contains acid that can burn
you. Do not get it on you. If you acciden-
tally get it in your eyes or on your skin,
flush the area with water and get medical
help immediately.
