209 Starting and driving
It is essential when a donor battery is to be
used to jump start the car that the jump
leads be connected correctly to prevent
arcing.
To jump start your vehicle:
1 Check the other vehicle. It must have a
12-volt battery with a negative ground
system.2 Get the vehicles close enough so the
jumper cables can reach, but be sure the
vehicles are not touching each other. If a
poor connection on the negative jumper
cable should exist, it is possible for
damage to be caused to electrical
systems/components of either vehicle
should inadvertent contact be made.
You would not be able to start your car
and bad grounding could damage the
electrical systems.
3 Turn off the ignition on both vehicles.
Turn off lights that are not needed, and
radios. This will avoid sparks and help
save both batteries and it could save
your radio.4 Open the hood and locate the battery.
Find the positive (+) and negative (–) termi-
nals on the battery.NOTICEIgnoring these steps could result in costly
damage to your vehicle that would not be
covered by your warranty.
Trying to start your car by pushing or pull-
ing it could damage your vehicle, even if
you have a manual transmission. If you
have an automatic transmission, your
vehicle cannot be started by pushing or
pulling it.
NOTICEIf the other system is not a 12-volt system
with a negative ground, both vehicles can
be damaged.
WARNING
You could be injured if the vehicles roll.
Set the parking brake firmly on each vehi-
cle. Put an automatic transmission in P
(Park) or a manual transmission in
Neutral.
NOTICEIf 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.Jump starting

210 Starting and driving5 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.
Using a battery charger3/starter
unitTo avoid damaging the car’s electrical
system and electronics, the following rules
must be followed when charging the battery
or jump starting the car.
 If the charger or starter unit can be set to
different voltages (6V/12V/18V/24V), 12V
must be selected.
 Follow the manufacturer’s instructions
supplied with the charger or starter unit.
 No other apparatus that are grounded or
connected to the mains must be
connected to the car during charging or
jump starting.
 The charger or starter unit must under no
conditions produce a voltage greater
than:
 16V continuous
 18V for 60 min.
If you are unsure about the charge rating of
the unit, disconnect the battery clamp from
the positive terminal before connecting the
unit to the battery.
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.93U S M 06.book Page 210 Friday, February 18, 2005 1:15 PM

211 Starting and driving
For long tripsBefore starting off on a long journey, it is
advisable to have your car inspected by
your Saab dealer.
Obtain a few important items to take along
on your journey, such as spare bulbs, wiper
blades, fuses, a drive belt (poly-V-belt) and
the like.
You can check some points yourself before-
hand:
 Check that no oil or fuel leaks out of the
engine or gearbox/transmission.
 Check the coolant and power steering
fluid levels. Check also for leaks.
 Inspect the drive belt (poly-V-belt) and
replace if it shows any signs of wear.
 Check the battery charge.
 Check the tires for tread pattern and air
pressure, including the compact spare
tire.
 Take an extra remote control and keep it
separate.
 Check the brakes.
 Check all bulbs.
 Check for the presence of the tool kit and
jack in the car.93U S M 06.book Page 211 Friday, February 18, 2005 1:15 PM

215 Car care
EngineTurbo petrol engineThe engine is a transverse four-cylinder in-
line engine with twin overhead camshafts
and 16 valves.
The engine is equipped with two balance-
shafts that reduce engine vibrations to a
minimum.
The balance shafts are chain-driven and
rotate at twice the speed of the crankshaft.
They produce forces and torques that are
opposed to those generated by the pistons
and connecting rods. The effect occurs
twice in each revolution of the engine, coun-
teracting the vibration from its moving parts,
and at the same time reducing unwanted
engine noise.
The gearbox, located on the right (viewed
from the front), is integrated with the engine.Petrol engine, V6The V6 engine is a turbocharged V6 engine
produced completely of aluminium with 60°
between the cylinder banks, 4 valves per
cylinder, 2 camshafts per bank.
The camshafts are driven via a chain trans-
mission. The engine is equipped with a
turbo whose turbine collects exhaust pres-
sure from both banks of cylinders.
To obtain optimum performance, fuel con-
sumption and low emission levels the
engine is equipped with CVCP (Continuous
Variable Cam Phasing). This means that
the engine’s intake camshafts can be adjusted to achieve optimum functionality.
The switches are hydraulic.
Engine familiesSaab cars imported into the United States
and Canada meet all applicable emission
control standards. The engine family and
appropriate tune-up specifications are iden-
tified on a label in the engine bay.
These engine families meet applicable EPA
Federal Standards, California State Stan-
dards and Canadian Federal Standards and
are equipped with the following systems:
 sequential multiport fuel injection system
 three way catalytic converter
 crankcase emissions control system
 evaporative emission system.
Emission control
systemsThe systems for controlling emissions to the
atmosphere require regular checking and
adjustment at the intervals specified in the
service program.
In addition to meeting the exhaust emission
regulations and thereby helping to keep the
environment clean, a correctly tuned engine
will also give maximum fuel economy.
WARNING
Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth
defects and reproductive harm. In addi-
tion, certain fluids contained in vehicles
and certain products of component wear
contain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.

216 Car careSaab Trionic engine
management systemThe Saab Trionic engine management
system is a unique Saab development that
combines sequential multiport fuel injection,
electronic distributorless ignition and turbo-
charger boost pressure control into one sys-
tem.
The Trionic engine control module (ECM)
monitors many different engine parameters
such as:
 Intake manifold pressure.
 Intake air temperature.
 Crankshaft position.
 Engine coolant temperature.
 Throttle position.
 The oxygen content of the exhaust gases.
The ECM receives information regarding
engine knocking from a sophisticated feed-
back function in the ignition discharge unit.
By processing all of this information, the Tri-
onic system can control fuel injector open-
ing duration, ignition timing and turbo-
charger boost pressure to provide excellent
engine performance while maintaining low
emissions and fuel consumption.
ORVR (Onboard Refueling Vapor
Recovery)All hydrocarbons formed when refueling will
be recovered by the car and not released
into the atmosphere. The hydrocarbons are
absorbed in an evaporative emission canis-
ter. When the engine is subsequently
started, the evaporative emission canister is
gradually purged as air is sucked into it
through a shut-off valve. The hydrocar-
bon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. “Refueling”, see
page 167.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 3 times.
NOTICEThe Trionic engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the Engine
malfunction (CHECK ENGINE) light in
the main instrument illuminates, the
Trionic ECM has detected a problem. The
car will continue to operate, but perfor-
mance may be diminished. You should
have your car checked by a Saab dealer
as soon as possible.

Engine oilChecking the oil levelCheck the engine oil level regularly.
1 Park the car on a level ground.
2 Switch off the engine and wait for
2–5 minutes. The engine should be at
normal operating temperature.
3 Take the dipstick out and wipe it off with
a clean rag before carrying out the
check.
The level must not be below the MIN mark
on the dipstick, but nor should it be above
the MAX mark. Excess engine oil could
result in abnormal oil consumption.
The distance between the MIN and MAX
marks is equivalent to 1.0 qt (1.0 l).2.0 Turbo (210 hk): The engine oil level is
checked each time the engine is started. If
the oil level is low, the following message
appears on the SID:
f this occurs the oil level must be checked
first. If the level is too low then it must be
topped up.V6: The engine has an oil level sensor that
checks the oil level when the engine is
running. If the oil level drops too low, the
following message appears on the SID:
f this occurs the oil level must be checked
first. If the level is too low then it must be
topped up.NOTICEToo high oil level can damage the engine.

220 Car careMake sure you screw on the oil filler cap
properly after topping up the oil to avoid
running problems.
It is normal for an engine to consume a cer-
tain amount of oil. It is therefore often nec-
essary to top up the oil between services.
Check the engine oil level regularly.
During the Break-in Period (approx.
3,000 miles or 5,000 km) and when driving
at high speeds or with a trailer, the oil con-
sumption may be higher than normal.
Changing engine oil
Engine oil and oil filter should be changed
according to the service program.
For oil volumes and grades, refer to
page 298.
The oil should be drained when the engine
is warm. The car must stand on level
ground.
1 Unscrew the drain plug in the bottom of
the sump and leave the oil to drain into a
suitable receptacle for at least
10 minutes. Take care, as the oil may be
hot.
2 Refit the drain plug with a new washer.
3 Change the oil filter once the engine oil
has drained (see page 221).
4 Fill with new oil.
Run the engine to normal temperature and
check the oil level.
NOTICEChange of engine oil and oil filter may be
required more frequently if the car is
being used under certain conditions, see
page 289.
WARNING
 Prolonged and repeated exposure of
the skin to engine oil can cause seri-
ous skin disorders. Avoid prolonged
skin contact whenever possible.
 Used engine oil contains chemicals
that have caused cancer in laboratory
animals. Always protect your skin by
washing thoroughly with soap and
water.
 Keep oil out of reach of children.
 Do not touch the turbocharger or
exhaust manifold. These get very hot
when the engine has been running.
 Do not spill oil on hot parts of the
engine as this could cause a fire. Used
engine oil is particularly flammable.
 Protect the environment. Do not
dispose of oil into the ground or down
a drain. Dispose of all used oil and
oil filters at an appropriate disposal
facility.

222 Car careAir filter
Transmission fluidManual transmission
Check and top up the oil in accordance with
the service program.
Automatic transmission
Check and top up the oil in accordance with
the service program.
CoolantIf the coolant level drops too low, the follow-
ing message appears on the SID:
The properties of the coolant are retained
for the entire service life of the car. There-
fore, it is not necessary to change the cool-
ant.The coolant contains 45 % antifreeze and
anti-corrosion fluid. This ratio gives the best
cooling effect. Lower concentrations should
be avoided, in view of the corrosion risk.
Other brands of antifreeze can damage the
engine and cooling system.
Note:
If incorrect coolant is used or added, the life-
time properties will be affected. Even if the
coolant is flushed from the system and
replaced with life-time coolant, life-time
properties are no longer retained and the
coolant must then be drained and replaced
at regular intervals.
WARNING
To ensure reliable operation, only use
an air filter recommended by Saab
Automobile AB.
WARNING
 Proceed with caution if the radiator is
boiling when you open the hood.
Never remove the expansion-tank
filler cap when the radiator is boiling.
 The cooling system is pressurized –
hot coolant and vapor can escape
when the filler cap is released. These
can cause injury to your eyes and
burns. Loosen the cap carefully, and
let the engine cool before removing
the cap.
 Exercise care when adding coolant.
Coolant on hot surfaces constitutes a
fire risk.
Coolant level low.
Refill.
NOTICEIf the cooling system needs topping up,
mix the antifreeze with the appropriate
quantity of drinking water or distilled
water before adding it to the system.
If undiluted antifreeze is added, the
engine could still freeze and be damaged.
This is because the antifreeze will not mix
properly with the coolant before the ther-
mostat has opened to allow full circula-
tion.

223 Car care
4-cyl engine: The expansion tank is trans-
parent to facilitate checking the coolant
level.
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, see
illustration).
Top up with a mixture of equal parts of anti-
freeze and clean water. We recommend
that you use a Saab-approved anti-freeze.
If the expansion tank is empty when coolant
is added, run the engine until warm so that
the thermostat opens. Top up the tank
again, as necessary.V6 engine: The expansion tank is not trans-
parent. The cap must be unscrewed so that
the coolant level can be checked. When the
cap is screwed off there are two level mark-
ings, MIN and MAX

Power steeringCheck the level of the power steering fluid in
the reservoir regularly, in accordance with
the service program.
The wheels should point directly forwards
during this check.
Clean round the cap before unscrewing it.
Wipe the dipstick. To check the level, screw
down the cap completely and then remove
it again.
The oil level should lie between the MAX
and MIN marks when the oil temperature is
about 68°F (+20°C). If the oil is colder, the
level will be lower, and at a higher tempera-
tures the level will be higher.
Top up with CHF 11S or CHF 202 power
