187 Starting and driving
Driving with a loadThe driving characteristics of the car are
affected by the way it is loaded.
 Place heavy loads as far forward and as
low as possible in the trunk.
 Secure the load to the tie downs, see
page 141.
 The load should be such that the car´s
total weight or axle weight are not
exceeded, see page 258.
 Heavy loads mean that the car’s center of
gravity is further back. As a result, the car
will sway more during evasive steering.
 Never exceed the permissible load in the
roof box, even if there is room for more.
 Ensure that the tire pressure is correct –
slight overinflation is preferable to under-
inflation.
 The braking distance of a loaded car is
always greater. Keep your distance from
the vehicle in front.
 Roof loads can negatively affect tele-
communication.
Tire pressure, see page 269 and back
cover.
Tires The tire pressure should match the current
load and speed of the car; see page 268 or
the tire pressure label on
page 269.
The tire pressures given apply to cold tires,
that is tires that are the same temperature
as the outside air temperature.
The tire pressure increases as the tires
become warm (e.g. during highway driving)
with approximately 0.3 bar (4 psi). When
the temperature of the tires changes by 50°
(10°C), the tire pressure will change 0.1 bar
(2 psi).Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Underinflated tires wear more quickly than
slightly overinflated tires.
If a valve is leaking, simply unscrew it and fit
a new one.
Important! Remember to adjust the tire
pressures if you change the load in the car
or intend to drive at substantially lower or
higher speeds than normal.
WARNING
Check the tire pressure at least once a
month and before long journeys. Under-
inflation can result in:
 Punctures
 Separation of the tire and tread
 Damage to the sidewalls
 Damage to the rims on poor roads
 Poor handling characteristics
 Premature tire wear
 Increased fuel consumption.

196 Starting and drivingParking on a hillWhen parking on a steep hill, turn the front
wheels so that they will be blocked by the
curb if the car should move. Long-term parkingIf the car is not going to be used for some
time, e.g. 3–4 months, the following steps
are recommended:
 Run the engine to normal temperature
before long-term parking.
 Drain the washer-fluid reservoir and
hoses.
 Wash and wax the car. Clean the rubber
seals on the hood, luggage compartment
lid and doors, and lubricate them with
glycerol (glycerin).
 After washing the car, dry the brake discs
by taking the car out on the road and
applying the brakes a few times.
 Fill the fuel tank with fuel to prevent con-
densation 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!
 Disconnect the negative (–) battery lead.
If frost is likely to occur during the
long-term parking, remove the battery
and store it away from the frost.
 Ideally, the car should be put up on
blocks, with the wheels off the ground. If
this is not possible, inflate the tires to
about 43 psi (300 kPa).  Leave all the windows open a crack and
cover the car with a fabric tarpaulin – not
one made of plastic.

201 Car care and technical information
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 affixed to the left front inner
fender.
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 control system.
 On-Board diagnostic (OBD II) 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
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 and
 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.
NOTICEThe Trionic engine management systems
continuously monitors the operation of
these systems and have on-board diag-
nostic capabilities (OBD II).
If the ”Engine malfunction (CHECK
ENGINE)” lamp in the main instru-
ment illuminates, this indicates that 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.

202 Car care and technical informationORVR (Onboard Refueling Vapor
Recovery)Hydrocarbon vapors formed when refueling
will be recovered by the car and not
released into the atmosphere. The hydro-
carbons are absorbed in a evaporative
emission canister. When the engine is sub-
sequently started, the evaporative emission
canister is gradually purged as air is sucked
into it through a shut-off valve. The hydro-
carbon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked at least 3 times. Otherwise, it is pos-
sible for the CHECK ENGINE light to illumi-
nate and a ”TIGHTEN FUEL FILLER CAP”
message to appear on SID.
Refueling, see page 158.
Engine2.3-liter engineThe 2.3-liter model is a transverse, 4-cylin-
der in-line engine with twin overhead cam-
shafts and 4 valves per cylinder.
This engine is equipped with balance shafts
that reduce engine vibration 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, an effect that occurs
twice for each revolution of the engine.
Engine noise is also reduced as the
counter-rotating shafts counteract the vibra-
tion from the moving parts of the engine.
The transmission, located on the right
(viewed from the front), is integrated with
the engine. All models have front-wheel
drive.
3.0t V6 engine The 3.0-liter engine is a transverse, V6
engine with each bank of cylinders having
double overhead camshafts and 4 valves
per cylinder.
The transmission, located on the right
(viewed from the front), is integrated with
the engine. All models have front-wheel
drive.

232 Car care and technical informationWheels Alternative wheels and tiresIf you wish to fit other tires or wheels than
those supplied with the car, consult your
Saab dealer first as to the possibilities avail-
able.
Wheels/tires combinations that are not
approved by Saab can negatively affect the
car´s directional stability, steering and brak-
ing in both wet and dry conditions.
Do not assume that a wheel/tire combina-
tion will function properly just because it will
bolt on.
The wheels and tires have been carefully
matched to the characteristics of the car and
play a key role in its outstanding roadhold-
ing and handling.
To ensure that the speedometer is as accu-
rate as possible it should be reprogrammed
if wheels of a different dimension are fitted.
Contact an authorized Saab workshop.
Tire pressureTires need to be inflated to suit the load car-
ried and the maximum speed the car will be
driven (see the recommended tire pres-
sures page 268). Note that all values apply
to cold tires. For tires with an aspect ratio
less than /60, increase the tire pressure by
3 psi (20 kPa) for rough roads with potholes
to minimize the risk of rim damage.
Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Soft tires will cause faster wear than
over-pressurized tires. They also increase
fuel consumption.
If a valve is leaking, simply unscrew it and fit
a new one.
NOTICEAlways consult your Saab dealer before
changing the wheels and tires on your
Saab.
Wide wheels and tyres with sidewalls that
are too low can:
 be damaged in potholes etc.
 cause springs, shock absorbers and
wheel bearings and body mountings
can be overloaded.
 cause that the wheels can come into
contact with chassis and body compo-
nents.
 can affect the function of the Elec-
tronic Stability Program (ESP).
The speed and load limits for the tires
must not be exceeded; see page 233.
Wheels larger than 17” must not be fitted.
The maximum permissible offset is
49 mm.
WARNING
Check the tire pressure at least once a
month and before long journeys. Under-
inflation can result in:
 Punctures
 Separation of the tire and tread
 Damage to the sidewalls
 Damage to the rims on poor roads
 Poor handling characteristics
 Premature tire wear
 Increased fuel consumption.

250 Car care and technical informationHeadlight aiming The 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.
 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 per-
pendicular 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
be correctly aimed if the low beam lamps
are aimed properly.
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.NOTICETo 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.
