190 Starting and drivingDriving 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 96).
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
disengaged 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
designated storage space.

194 Starting and drivingIt 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

195 Starting and driving
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.
Using a battery charger/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.

200 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 153.
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.

208 Car careBattery
Check the charge state and electrolyte level
of the battery regularly.If frequent short journeys are made, the
battery 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 210). 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
battery.
 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
NOTICEA 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.
Contact Saab dealer.
Checking the battery electrolyte level.
Level correct if level indicator dark.
Battery should be changed if indicator is
light

213 Car care
Changing bulbsAutochecking 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 displayed on the SID.
Example of SID message:
The following bulbs are not checked: parking lights, front fog lights,
reversing lights, license plate lighting, side marker lights and side
direction indicators.If a stop light bulb fails
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.
Wrong bulb fitted
If a dipped or main beam bulb of too high a rating is fitted, a bulb
failure message will be shown on the SID (a too high wattage bulb
can damage the reflector).
If the following message is displayed but the bulb shines, it is most
likely that an incorrect bulb has been fitted.
Note:
When changing bulbs, fit the same type of bulb (e.g. Long-Life)
as that removed.
Headlight aiming, page 258.
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.NOTICESwitch off the ignition before changing a bulb, to avoid possible
short-circuiting.
Left low beam failure.
Right high beam failure.

258 Car careNote:
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 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.
If you find that the headlight needs adjust-
ment follow these steps:
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.
