This light comes on when the battery is not
being charged by the alternator. If the light
comes on during driving, stop as soon as
possible and switch off the engine.
The following message is shown on the
Saab Information Display (SID):
Check the drive belt, see page 219.
The light illuminates if the tire pressure in
one or more tires is too low, see page 257.
Below is an example of the message simul-
taneously shown on the SID:This light will come on if the engine oil pres-
sure is too low. If the warning light flashes or
comes on while you are driving, stop imme-
diately in a safe place, switch off the engine
and check the oil level (see page 210).
The following message is shown on the
Saab Information Display (SID):
This light indicates a malfunction in the fuel
or ignition system.
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to
fully install the cap. See Fuel cap on
page 160. The diagnostic system can deter-
mine if the fuel cap has been left off or
improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the

Engine malfunction
(CHECK ENGINE)
WARNING
An illuminated “Engine malfunction
(CHECK ENGINE)” indicator light indi-
cates an engine-related problem. While
your car may be able to be driven with the
“Engine malfunction (CHECK ENGINE)”
indicator light illuminated (limp-home
mode), you are advised to have your car
serviced at an authorized Saab dealer as
soon as possible.
Continued driving without this problem
being corrected might cause serious fur-
ther damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g. brake
smoothly, engage neutral, stop in a suita-
ble place, switch off the engine, etc.)

89 Instruments and controls
If the needle repeatedly enters the red zone
and the engine at the same time loses
power, because the monitoring system is
limiting the boost pressure, you should
contact a Saab dealer as soon as possible.
If the speed of the car exceeds 143 mph
(230 km/h), acceleration is limited by reduc-
ing the boost pressure. The pressure gauge
then moves towards the middle of the white
field, indicating a drop in engine power and
consequently the car’s speed.
Fuel gaugeWhen less than about 2.5 gallons (10 litre)
of fuel is left in the tank, a warning light on
the main instrument panel comes on.
Refueling, see page 159.
Saab Information
Display (SID)Various types of information are shown on
the SID: warnings, indications, trip
computer information and information
from the car’s Infotainment System.
Selected gear is shown on the left-hand
side of the display. When gears are
selected manually, the letter M (manual)
and the selected gear are displayed (see
page 170) (cars with automatic transmis-
sion).
In the first row trip computer information is
displayed and in the second row odome-
ter and tripmeter is displayed.
When a message is displayed
The odometer and tripmeter is temporarily
turned off when a two row message is dis-
played. The icon is displayed in the left part
of the display.
The warnings and indications that can be
shown on the SID are listed on page 300.
If there is more than one message on the
SID, a plus sign will be displayed to the left
of the first message. Each message will be
displayed for 10 seconds.

156 Starting and drivingImportant
considerations for
driving1 Starting and driving
Do not use full throttle until the engine
is warm, so as to avoid unnecessary
wear. If the needle of the turbo gauge
repeatedly enters the red zone, the
engine may suddenly lose power, due
to the initiation of a monitoring system
that limits the boost pressure. We
recommend that you contact a Saab
dealer as soon as possible.
Under certain barometric conditions
(high outside temperature and/or high
altitude) the needle may enter the first
part of the red zone without necessarily
indicating that a fault has arisen.
A protective function (interruption of the
fuel supply) limits the engine speed.2 Stopping the engine
Do not rev the engine immediately
before switching it off - stop the engine
when it is idling.
3 Regulating the boost pressure
One of the advantages of boost pres-
sure regulation is that the engine can
also be run safely on gasoline with a
lower octane rating, although not lower
than AON 87. However, engine perfor-
mance will fall slightly and heavy load-
ing and laboring should be avoided. For
optimum performance, use the recom-
mended grade of fuel.
The maximum boost pressure is regu-
lated according to the tendency of the
engine to knock. Short-lived knocking
is perfectly normal. This can occur
when the engine is running at about
3,000 rpm under a heavy load. The
extent of this knocking will depend on
the grade of fuel in the tank.
Isolated instances of knocking can
occur with low-octane fuel. This
controlled form of knocking, followed by
a reduction in the boost pressure, is a
sign that the control system is working
normally, and is perfectly safe for the
engine.The light comes on in the event of an engine
or gearbox fault (cars with automatic gear-
box), which may cause drivability problems
but that does not affect exhaust emission.
The car can still be driven but perhaps with
limited performance.
Contact a dealer whenever an opportunity
occurs. We recommend that you contact a
Saab dealer.
NOTEIf the engine sounds strange there is a
malfunction. We recommend that you
contact a Saab dealer immediately.
The use of fuel with too low an octane
rating can cause serious engine dam-
age.
Limited performance.

181 Starting and driving
Long-term parkingIf the car is not going to be used for some
time, e.g. three to four months, the following
steps are recommended:
Drain the washer fluid reservoir and
hoses.
Wash and wax the car. Clean the rubber
seals on the hood, trunk lid and doors,
and lubricate them with glycerol
(glycerine).
After washing the car, dry the brake discs
to avoid corrosion by taking the car out on
the road and applying the brakes a few
times.
Fill the fuel tank to prevent condensation
forming in it.
Top up the coolant and check the anti-
freeze before the onset of winter.Park the car in a dry, covered and
well-ventilated building. Leave the park-
ing brake OFF!
Convertible: If the car is stored, the soft
top should be closed.
If necessary, use wheel chocks and leave
the parking brake off.
Disconnect the negative (–) battery lead.
If frost is likely to occur during the storage
period, remove the battery and store it in
a frost-free place.
If it is not possible to stand the car on axle
stands, increase the tire pressure to
43 psi (3 bar).
Leave all the door windows open a crack
and cover the car with a non-plastic
tarpaulin – not one made of plastic which will
not breath.93_US_M08.book Page 181 Friday, May 11, 2007 11:37 AM

186 Starting and drivingto reach its optimum temperature, and
engine 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 heater3
33 3The 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.

202 Starting and drivingUsing a battery charger3
33 3/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 (6 V/12 V/18 V/24 V),
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:
16 V continuous
18 V for 60 minutes.
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.
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.

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.

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.
