The electronic control module for the auto-
matic transmission receives information on
engine torque and road speed, and also
controls the hydraulic pressure in the trans-
mission to ensure that gear changing is as
smooth as possible.
The position of the selector lever is shown
by the symbols adjacent to the lever and
also by a symbol on the main instrument
panel. If manual mode (M) is selected, the
current gear is also displayed on the main
instrument panel.
The ignition key can only be removed when
the selector lever is in the P position.
NOTEWhen the reverse gear is to be engaged
the car must be at a standstill with the
accelerator fully released. Lift the reverse
lock-out collar and push the gear lever
firmly to the right in neutral before easing
it into reverse.
WARNING
Make it a habit to keep your foot on the
brake when selecting a drive position,
to prevent the car from creeping for-
ward (or backward if reverse is
selected).
The car must be at a standstill before
P, R or N is selected. You have to have
your foot on the brake pedal to move
the lever out of P. If the car is still
moving when a drive position is subse-
quently selected, this could cause a
crash or damage the automatic trans-
mission.
Never park the car with the selector
lever in a drive position, even if the
parking brake is on.
If you want to leave the car with the
engine running, move the selector
lever to P or N and apply the parking
brake.

153 Starting and driving
Lock-up function The automatic transmission has a lock-up
function, which can render the torque con-
verter inoperative in 3rd, 4th and 5th gears,
thus reducing the engine speed and fuel
consumption.
When the lock-up function comes into oper-
ation, it may give the impression of an over-
drive being engaged.Kick-downWhen the accelerator is pressed down hard,
a change-down to the next gear will be
effected to provide maximum acceleration,
e.g. for overtaking.
Following this, the next higher gear will be
selected at the optimum engine speed for
acceleration or, if you ease off the acceler-
ator, before reaching this.
Park Brake Shift LockThe transmission has a security function
known as Park Brake Shift Lock. To move
the gear selector out of the P position, the
brake pedal must be depressed at the same
time as the gear selector catch (detent) is
pressed in.
Shift Lock override
Check fuse No. 1 (see page 218). If the
problem was cured by changing the fuse or
battery, you do not have to contact a work-
shop.
If the fuse blows again as soon as the Shift
Lock feature is activated you should contact
a workshop. We recommend that you con-
tact an authorized Saab dealer.If the fuse is OK, check the battery regarding
the voltage.
1 Apply the parking brake
2 Make sure the key is in position ON
3 Use a small tool such as a screwdriver
and push the lever (see picture) down-
wards so that the detent button can be
pressed approx. 10 mm
4 Move the selector out of position P to N
5 Remove the tool
6 Release the parking brake if the car is to
be moved immediately; otherwise keep
it applied.NOTEDue to electrical problems it may not be
possible to move the selector out of the
park position, even if the ignition is ON. If
for some reason the selector has to be
moved out of the park position (i.e. to tow
the car a short distance) do as described
below.

158 Starting and drivingIf you move the selector lever from D to L, down shifts will follow a
set pattern to avoid damaging the engine or transmission.
Manual gear-changing is not recommended on slippery roads.
If one of the drive wheels spins excessively, the engine torque will
be reduced to avoid damaging the transmission.Adaptive gear-change patternsAdaptive gear-change patterns are selected automatically depend-
ing on the engine load and the present temperature of the transmis-
sion. The function is available in Normal and Sport modes.
The changes occur at a higher engine speed and the car remains in
the same gear for longer, if the transmission control module senses
that the load has not decreased. These gear-change patterns pre-
vent unnecessary changing up and down, when for example driving
up or down long slopes with a trailer or caravan, and to prevent over-
heating the transmission oil. The adaptive gear-change function is
also selected automatically when the transmission oil becomes too
hot, to protect the transmission itself from damage and to lower the
oil temperature.
The adaptive gear-change pattern function is deselected when:
The engine is switched off.
The load is reduced so much that the function is no longer
required.
”Automatic transmission3, fault indicator” appears on main
instrument panel, see page 154.
SPORT modes
To select Sport mode, press the ”S” button on
the selector lever when the selector lever is in
position N or D.
In this mode, gear changes will take place at
higher engine speeds than in Normal mode, in
other words, the transmission will change up
later and change down earlier for the same throt-
tle (accelerator) position.
The Sport mode will be deselected if:
The SPORT button is pressed.
The selector lever is moved to position P,R, M
or L.
The engine is switched off.
”Automatic transmission3, fault indicator”
appears on main instrument panel, see
page 154.

176 Starting and drivingWhen negotiating long hills, bear the follow-
ing important considerations in mind:
Use Normal mode when driving with a
caravan or trailer on hilly roads. The adap-
tive gear change pattern function will
prevent the transmission overheating.
Rises in coolant temperature are indi-
cated by the temperature gauge in the
main instrument panel.Recommendations for cars with
automatic transmission
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following steps are taken in order as the
temperature of the engine increases:
Gear change pattern is altered.
A/C compressor is switched off.
Engine torque is reduced.
The following message will be displayed on
the SID if the transmission fluid becomes
too hot:
“Gearbox too hot.
Make a safe stop.
If this message appears, stop the car as
soon as it is safe to do so and allow the
engine to idle until the message has gone
out. The selector lever should be in
position P.When continuing your journey, select
manual mode and a gear in which the
engine speed is about 3,000 rpm until the
incline eases (see page 157).
WARNING
Remember to use the braking effect of the
engine (position D or L) when you are
descending long or steep hills to spare
the brakes.
Brake failure can result from overheated
brakes!

Driving considerations Always take extra care when towing a
trailer, as the car’s handling will be different
and its braking effect reduced. The trailer’s
braking system and suspension also have a
considerable effect on these characteris-
tics, see also ”Driving with a load” page 181.
If the car has automatic transmission, select
position D when ascending steep hills. This
ensures that the adaptive gear change pat-
terns are operational, see page 158. Use
position D or L for steep descents.Checks before drivingMake sure that the car and camper or trailer
are in good working order. This is essential
since towing a camper or trailer increases
the strain on the car.
Check and if necessary adjust the tire
pressure of the car and camper or trailer.
Make sure all wheel bolts are properly
tightened.
Make sure that the equipment joining the
car and camper or trailer is properly
secured and adjusted.Make sure the camper or trailer’s electri-
cal cable is properly connected and is not
so long that it drags along the ground.
Also, make sure the cable is not too short
and risks breaking when turning a corner.
Check all bulbs.
Check the car and camper or trailer
brakes.
Make sure that all items on or in the cara-
van or trailer are properly secured.
Make sure that the camper or trailer’s
jockey wheel is raised and locked.
Check the distribution of the load so that
the car and camper or trailer are well
balanced.
Check that the rearview mirrors provide
the best possible rearward vision.
Make sure the camper or trailer’s safety
cable is correctly attached.
WARNING
Utilize the braking effect of the engine
(1st, 2nd or 3rd gear) when you are
descending long or steep hills to spare
the brakes.
Brake failure can result from overheated
brakes!
NOTEIf the ”Automatic transmission3, fault
indicator” indicator comes on, cease
towing until the problem has been recti-
fied.

194 Car care and technical informationEngineThe 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.
Engine oilChecking the oil level Check the engine-oil level regularly. This
should be done after the engine has been
run to normal temperature and then allowed
to cool for 2–5 minutes, with the car stand-
ing on level ground. Remove the dipstick
and wipe it clean before checking the level.The oil level must not be allowed to drop
below the MIN mark on the dipstick, nor
should oil be filled beyond the MAX mark, as
this can lead to excessive oil consumption.
The distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 1.05 qts (1 liter).
When necessary, add oil of the recom-
mended grade via the dipstick tube.
Recommended oil grade, see page 263.
NOTEDo not operate the engine with a low
oil level.
Change engine oil and oil filter as pre-
scribed in the service programme.
Only use the recommended oil type.
Follow the three points listed above to
avoid severe engine damage.
More frequent oil changes are recom-
mended if your vehicle is operated under
certain conditions, see page 254.

200 Car care and technical informationCharging/replacing the battery Connect the positive lead to the positive (+)
battery terminal (red), and the negative lead
to a good ground point, e.g. the lifting lug at
the front of the engine.
To remove the battery, always disconnect
the negative (black) lead first and reconnect
it last when fitting the new battery.
The battery size must comply with DIN
53735 MFI 230/2.16.

NOTETo avert the danger of short-circuiting
between the positive (+) terminal on the
battery and the inlet manifold on the
engine, always disconnect the negative
(–) battery lead first and reconnect it last.
NOTEIf boost charging never use anything
but a 12-volt charger, see page 188.
Never reverse the polarity of the bat-
tery by connecting the leads to the
wrong terminals. The red, positive
lead connects to the positive (+) termi-
nal, and the black, negative lead to the
negative (–) terminal.
Serious damage can occur to the car´s
electrical system if a battery or alterna-
tor lead is disconnected while the
engine is running.
The nut on the battery clamp should
be tightened to a torque of 10 Nm.

239 Car care and technical information
Changing a wheel
WARNING
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
flat tire. If it is used for anything else, you
or others could be badly injured or killed if
the vehicle slips off the jack. Use the jack
provided with your vehicle only for chang-
ing a flat tire.
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire. To
help prevent the vehicle from moving:
1 Set the parking brake firmly.
2 If you have an automatic transmis-
sion, put the shift lever in PARK (P).
For a manual transmission, leave the
car in gear (1st or REVERSE (R)).
3 Turn off the engine and do not restart
while the vehicle is raised.
4 Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle won't
move, you should put blocks at the front
and rear of the tire farthest away from the
one being changed. That would be the
tire, on the other side, at the opposite end
of the vehicle.
The car jack is designed solely for use
in changing a wheel or fitting snow
chains. It must not be used to sup-
port the car during repair work or
servicing.
Never crawl under a car that is
supported only by a jack.
Raising your vehicle too high or with
the jack improperly positioned can
damage the vehicle and even make
the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to
fit the jack lift head into the proper
location before raising the vehicle, and
raise the vehicle only far enough off
the ground so there is enough room
for the spare tire to fit (no more than
25 mm or 1 inch clearance between
the ground and the bottom of the tire).
Switch on the hazard warning lights if
the car is on a road.
The jack should be stored correctly
under the carpeting in the trunk. If it
lies loose in the car, it could thrown for-
ward and cause personal injury in the
event of a crash or if the car rolls over.
Grit, salt and rust can clog the inner
threads of the wheel bolts if the car has
been driven for several years exclu-
sively with alloy wheels.
If steel wheels are being installed, the
bolt hole threads in the brake hubs
should be cleaned before the thinner
steel wheels are fitted. It may other-
wise not be possible to achieve the
correct clamping force, despite tight-
ening the wheel bolts to the correct
torque.
