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 157.
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 168) (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 temporarely
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 296.
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.

154 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 work-
ing normally, and is perfectly safe for
the engine.The light3 comes on in the event of an
engine or gearbox fault (cars with automatic
gearbox), which can cause drivability prob-
lems. The car can still be driven but perhaps
with limited performance.
Contact a workshop when you find it suit-
ably. We recommend that you contact an
authorised Saab workshop.
NOTICE If 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
damage.
Limited performance.

179 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 parking
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_U S _M 07.book Page 179 W ednesday, April 12, 2006 9:30 AM

184 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
prevailing 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.

200 Starting and drivingUsing 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.
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.

203 Car care
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.
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.

204 Car careBosch 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 157.
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 workshop as
soon as possible. We recommend that
you contact a Saab dealer.

241 Car care
TiresYour new vehicle comes with high-quality
tires made by a leading tire manufacturer. If
you ever have questions about your tire
warranty and where to obtain service, see
your Saab Warranty and Service Record
Booklet for details.
Inflation - Tire PressureThe Tire-Loading Information label shows
the correct inflation pressures for your tires
when they’re cold. “Cold” means your vehi-
cle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).Notice:
Don’t let anyone tell you that
underinflation or overinflation is all
right. It’s not. If your tires don’t have
enough air (underinflation), you can get
the following:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy
If your tires have too much air (overinfla-
tion), you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazardsAdjust the tire pressure to match the current
load and speed of the car (see page 292).
The stated tire pressures apply to cold tires,
i.e. tires that are the same temperature as
the outside air temperature. Tire pressure
increases as the tires become warm (e.g.
during highway driving) by approximately
4 psi (28 kPa). When the temperature of the
tires changes by 50°F (10°C), the tire pres-
sure will change 2 psi (14 kPa).
Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
WARNING
Poor maintained and improperly used
tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
friction. You could have an blow-out
and a serious accident. See “” on
page 251.
Underinflated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact – such as when you hit a
pothole. Keep tires at the recom-
mended pressure.
Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.93_U S _M 07.book Page 241 W ednesday, April 12, 2006 9:30 AM
