2008 SAAB 9-3 check engine light

197 Starting and driving
Driving at nightBear in mind the following points, especially
when driving at night:
Nighttime driving requires your full
concentration
Do not rush. Count on your journey taking
slightly longer.
The number of drivers under the influence
of drugs is likely to be greater at night than
during the day.
Do not stare at the headlights of oncom-
ing vehicles.
Avoid driving at night if you have poor
eyesight. Night vision deteriorates with
age.
Keep your car’s headlights, windows and
mirrors clean. Also, if you wear glasses,
make sure they are clean.
Make sure you are well rested before
starting a long journey. Take a break every
other hour.
Only eat light meals. Heavy meals have a
tendency to induce tiredness.
Wild animals prefer to move at dusk and
dawn.
Check the headlight levelling setting (see
page 98).
Towing the car
Front towing eye
WARNING
Remember that the brake servo does
not operate when the engine is off.
Much greater pressure than normal
will therefore be required to operate
the brake pedal.
Nor does the steering servo operate
when the engine is off. The steering
will therefore be much heavier than
usual.
The towing vehicle should always be
heavier than the vehicle on tow.
Never allow passengers to ride in the
car when it is on tow.
Always seek professional help if the
car needs to be recovered.
The ignition switch must be in the ON
position if the car is moved with the
engine not running.
The steering wheel lock must be dis-
engaged before towing the car.
The steering wheel lock disengages
when the remote control is inserted
into the ignition switch, if the battery
has sufficient charge.
WARNING
Make sure that the towing eye is
screwed in tightly. It has a left-hand
thread!
The towing eye is only designed for
towing the car on roads. It must not
be used to pull the car out of a ditch,
for example.
Make sure that all bystanders keep a
suitable distance, in case the towing
eye or tow rope should snap. The
towing eye or tow rope could catapult
off and cause seriously injury.
Never drive with the towing eye fitted
to the front bumper. Return it to its des-
ignated storage space.

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.

206 Car careEmission 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.
Saab Trionic engine
management system, 4-cyl
engineThe 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.
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.
NOTEThe 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 Tri-
onic 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 workshop as
soon as possible. We recommend that
you contact a Saab dealer.

Bosch ME9 engine management
system, V6 engineThe Bosch ME9 engine management
system is a system that combines sequen-
tial multiport fuel injection, electronic distrib-
utorless ignition and turbocharger boost
pressure control into one system and intake
camshaft phasing control.
The ME9 engine control module (ECM)
monitors many different engine parameters
such as:
Charge air pressure.
Intake air temperature.
Crankshaft position.
Engine coolant temperature.
Throttle position.
The oxygen content of the exhaust gases.
By processing all of this information, the
ME9 system can control fuel injector open-
ing duration, ignition timing, intake camshaft
phasing and turbocharger boost pressure to
provide excellent engine performance while
maintaining low emissions and fuel con-
sumption.
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 159.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 3 times.
NOTEThe ME9 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 ME9
ECM has detected a problem. The car will
continue to operate, but performance
may be diminished. You should have your
car checked by a workshop as soon as
possible. We recommend that you con-
tact a Saab dealer.

216 Car careBattery
Check the charge state and electrolyte level
of the battery regularly.
If frequent short journeys are made, the bat-
tery may need extra charging. This can be
done with a battery charger or by taking the
car for a long run.
If the battery is not being charged while the
engine is running, the following message
will appear on the SID:
Check the drive belt (see page 219). If the
belt is damaged, the engine may overheat,
the battery may not be charged and the A/C
compressor may not work.
WARNING
When working on the battery, highly
explosive gas can build up. A spark
could ignite this gas that collects
around the battery.
Therefore, always avoid sparks and
open flames in the vicinity of the bat-
tery.
The battery contains corrosive sulphu-
ric acid. Always wear a face mask or
goggles when working on the battery.
If battery acid gets into the eyes or
splashes onto skin or clothing, wash
the affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash your hands after
handling
NOTEA discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from sub-zero temperatures.
Battery not charging.
Make a safe stop.
Checking the battery electrolyte level.
Dark or green level indicator means
correct fluid level.
Battery should be changed if indicator is
light

222 Car careWasher jetsThe washer jets, which are adjustable, can
be cleaned with a pin if necessary.
Changing bulbs
Autochecking of lightsThe bulbs that are most important from the
point of view of traffic safety are monitored
by the car’s electrical system. If one of these
bulbs should fail, a message will be dis-
played on the SID.
Example of SID message:
The following bulbs are not checked: park-
ing lights, front fog lights, reversing lights,
license plate lighting, side marker lights and
side direction indicators.
SportCombi
The tail lights and brake lights consist of
LEDs. If approx. 3/4 of the LEDs on one side
are broken then this is indicated in the SID.
If a stop light bulb fails
SportSedan: If a stop light bulb fails, the
adjacent taillight will act as a stop light to
ensure traffic safety. Change the broken
bulb when possible.
All rear light bulbs are of the same type and
rated 21 W, with the exception of the license
plate lighting which is rated 5 W.
WARNING
Before changing a bulb in the engine
bay, switch off the engine to avoid the
danger of fingers and hands being
injured by moving parts.
The radiator fan can cut in even when the
engine is switched off.NOTESwitch off the ignition before changing a
bulb, to avoid possible short-circuiting.
Left low beam failure.

275 Car care
Other than in extremely cold weather, do not
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.
Applicable to the manual climate control
system - During cold months the air condi-
tioning should be switched on once or
twice a month and run for 5–10 minutes
during highway driving once the engine is
warm.
This action saves the gaskets in the
compressor from being spoiled. The
compressor uses a lubricant that circu-
lates with the coolant.
Note
The A/C system cannot be switched on
when the outside temperature is below 32°F
(0°C). Turn on the A/C system when the car
is standing in a warm place. Simplest is to
always have the A/C button pressed in. The
A/C system will then cut in automatically
when the outside temperature is high
enough.
Headlight aimingThe vehicle has a visual optical headlight
aiming system equipped with vertical
aiming device. The aim has been preset at
the factory and should normally not need
further adjustments.
If your headlights are damaged in a crash,
the headlight aim may be affected. If you
believe your headlights need to be
re-aimed, we recommend that you take it to
your Saab dealer for service. However, it is
possible for you to re-aim your headlights as
described in the following procedure.To check the aim, the vehicle should be
properly prepared as follows:
The vehicle shall be placed so that the
headlights are 25 ft (7.6 m) from a light
colored wall or other flat surface. The
aiming area should be darkened, this will
improve your ability to see the beam of the
low beam headlight being aimed.
An optical headlamp aimer can also be
used and will than replace the wall.
The vehicle must have all four wheels on
a perfectly level surface which is level all
the way to the wall or other flat surface.
The vehicle should be placed so it is
perpendicular to the wall or other flat
surface.
The vehicle should be unloaded and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat.
The vehicle should be fully assembled
and all other work stopped while headlight
aiming is being done.
The vehicle should not have any snow, ice
or mud attached to it.
Tires should be inflated to the prescribed
pressure.
Close all doors.
Rock the vehicle to stabilize the suspen-
sion.
Headlight aiming is done with the vehicle
low beam lamps. The high beam lamps will
WARNING
Before checking/adjusting the headlight
aiming, switch off the engine to avoid
danger of fingers and hands being injured
by moving parts.
The radiator fan can start up even when
the engine is switched off.NOTETo make sure that your headlights are
aimed properly read all instructions
before beginning. Failure to follow these
instructions could cause damage to
headlight parts or a not correctly aimed
headlight.
