2008 SAAB 9-3 automatic transmission

155 Starting and driving
Starting the engineAvoid racing the engine or loading it heavily
before it has warmed up. Do not drive away
before the warning and indicator lights have
gone out.
The engine has an automatic choke and
should be started as follows:
Cars with manual transmission
To start the engine the clutch pedal must
be fully depressed.
1 Make sure the parking brake is applied.
2 Depress the clutch pedal but do not
touch the accelerator.
3 Start the engine. Let the ignition switch
spring back as soon as the engine has
started and is running smoothly.
Allow the engine to idle for about
10 seconds. Do not apply full throttle for at
least 3 minutes after starting.Cars with automatic transmission
The selector lever must be in the P or N
position.
1 The selector lever must be in the P or N
position.
2 Keep your foot on the brake pedal.
Note! Once the engine has started, the
brake pedal will sink. This is perfectly
normal.
3 Start the engine. Let the ignition switch
spring back as soon as the engine has
started and is running smoothly.
Allow the engine to idle for about
10 seconds. Do not apply full throttle for at
least 3 minutes after starting.
Useful tips on starting the engineIf the engine has failed to start after several
attempts in very cold weather, proceed as
follows:
1 Turn the ignition switch to ON (it is
essential that you turn the ignition to
ON before depressing the accelerator).
2 Press the accelerator to the floor and run
the starter motor for 5-10 seconds. This
will prevent the engine being flooded
(fully depressed accelerator cuts off the
fuel supply).
3 Now start the engine in the normal way
- do not touch the accelerator.
If the engine stalls immediately after starting
(e.g. if the clutch was released too quickly),
do not touch the accelerator when restarting
the engine.

165 Starting and driving
Automatic
transmission3
33 3The automatic transmission has an elec-
tronic control module. The control module
receives information including accelerator
position and road speed. Using this and
other information, it controls the hydraulic
pressure of the transmission to ensure that
gear changing is as smooth as possible.The remote control can only be removed
when the selector lever is in the P position.The engine can only be started when the
selector lever is in the P or N position.
When the car is stationary, the engine must
be idling when you move the selector lever
from one position to another. If not, the
transmission could be damaged.
WARNING
Depress the brake pedal when shifting
the selector lever from P or N.
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.
NOTEAfter selecting a drive position, pause
briefly to allow the gear to engage (the car
starts to pull a little) before you acceler-
ate.

166 Starting and drivingPark Brake Shift LockThe transmission has a security function
known as Park Brake Shift Lock. To move
the gear selector lever out of the P or N posi-
tion, the gear selector lever detent (catch)
must be pressed in at the same time as the
brake pedal is held depressed.
The detent button on the selector lever has
to be pressed in before the lever can be
moved between certain positions.
Temporary override of Park Brake Shift
Lock, see page 168.
Adaptive gear change patternsThe adaptive gear change pattern function
adapts gear changing to the prevailing driv-
ing conditions. The transmission control
module senses the engine load, vehicle
speed and temperature of the transmission.
A suitable gear change pattern is then
selected automatically to avoid unneces-
sary gear changes and undesired increases
in transmission temperature.
Certain variants use a special change pat-
tern for the first few minutes after a cold start
so that the catalytic converter reaches its
working temperature more quickly.
Thermal transmission protectionThe transmission has built-in protection
against overheating. If the temperature of
the transmission fluid exceeds 302°F
(150°C), engine torque will be limited to
147 ft.lbs. (200 Nm).
The following message is shown on the SID:
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.Gearbox too hot. Make a
safe stop. Open hood.

Sport mode3
33 3
Sport mode is selected using the
button, while the word SPORT illuminates
on the SID . Changing up occurs later
and changing down occurs earlier at the
same accelerator pedal position.
Sport mode will be deselected if:
The Sport button is depressed again
the engine is switched off.
Lock-upThe transmission’s torque converter has a
lock-up function. This can lock the torque
converter, thus reducing the engine speed
and fuel consumption.Kick-downWhen the accelerator is pressed down fully,
a down change is made to optimize acceler-
ation, e.g. for overtaking.
Following this, the next higher gear will be
selected at the optimum engine speed,
unless you ease off the accelerator before
reaching this.Driving in hilly country with a
heavy loadThe transmission fluid can overheat when
the gearbox is strained, for example, when
driving with a trailer on hilly roads. To avoid
the transmission fluid overheating, always
drive with the selector lever in the D posi-
tion. The adaptive gear change patterns are
then active.
High air temperatures or a faulty oil cooler
can also cause the transmission fluid to
overheat. Overheating reduces the service
life of the fluid.
TowingTowing of cars with automatic transmission,
see page 197.Descending hillsIf the speed of the car increases while
descending a steep hill, despite the acceler-
ator being released, the control module will
change down. If you desire more powerful
engine braking, manually select a lower
gear (see page 170).
WARNING
Remember to use the braking effect of the
engine (1st, 2nd or 3rd gear) when you
are descending long or steep hills to
spare the brakes.
Overheating can cause the brakes to
fade!

169 Starting and driving
Selector lever positions
P
The selector lever is locked and the transmission
is mechanically blocked.
The engine can be started.
To move the selector lever out of the P position,
depress the brake pedal and press in the detent
(catch) on the selector lever.
Only select the park position (P) when the car is
stationary.
R
Only select the reverse position (R) when the car
stationary. The detent release button must be
pressed before the selector lever can be moved
to R.
Wait until reverse gear has engaged before
touching the accelerator.
N
You must press the brake pedal to move
the selector lever from the neutral position (N).
In neutral, the transmission is disengaged from the
engine. The engine can be started but make sure
the parking brake is on to prevent unexpected
movement.
To prevent the engine and transmission becoming
hotter than necessary, select N for long stops with
the engine running, e.g. when stuck in a traffic jam.
At traffic lights, leave the selector lever in the drive
position (D).
D
The drive position (D) is the normal one for forward
driving. The transmission shifts automatically
between all gears from 1st to 5th or 6th, the timing
of which depends on factors such as the current
accelerator position and the speed of the car.
Pause for a moment before applying the acce-
lerator, to allow the gears to engage.

172 Starting and drivingTo reduce the preset speedYou can reduce speed in any of the follow-
ing ways:
Brake to the desired speed. Jog the
control to SET/+ or SET/–.
Jog the control to SET/– to reduce the
speed by 1 mph (1.6 km/h).
Hold the control in the SET/– position until
the desired speed is reached.Temporary increase in speedAccelerate, without shifting down (manual
transmission), to exceed the set speed such
as for overtaking. When you release the
accelerator, the car will return to the set
speed.To disengage the system
temporarilySlide the switch to the left towards OFF, but
only as far as to disengage the cruise con-
trol. Allow the switch to spring back.
To re-engage the systemSlide the switch to RESUME. The car will
return to the previously set speed. Vehicle
speed must exceed 15 mph (25 km/h).To disengage the systemThe system will be disengaged:
As soon as the brake or clutch pedal is
depressed (cars with manual transmis-
sion).
When the switch is slid towards OFF. See
also heading "To disengage the system
temporarily".
When the switch is slid to OFF.
When the TCS/ESP
® system is operative.
When position N is selected (cars with
automatic transmission).
BrakingIt is good practice to try your brakes period-
ically while driving. This is particularly
important when driving in heavy rain, on
roads with a lot of surface water, in snow or
in salty slush. In such conditions a slight
delay in the braking effect may be noticed.
To minimize this delay, dry the brakes by
applying them lightly now and again. This
should also be done after the car has been
washed, and in extremely damp weather.
To avoid the brakes becoming overheated,
such as when negotiating long descents
with a drop of several hundred yards (hun-
dred metres), select a low gear to utilize the
braking effect of the engine. If the car has
automatic transmission, select 1st or 2nd
gear.
You can help to prolong the life of the brakes
by thinking ahead and braking harder over
short periods, rather than braking more
moderately over long stretches.

188 Starting and drivingRemember that tires age: it may therefore
be necessary to change winter tires before
they reach the legal wear limit, as they grad-
ually lose their friction properties with age.
If you get into a front wheel skid and the car
has a manual transmission, the best
response is to freewheel, which means
declutching so that the wheels neither drive
nor brake, and to cautiously steer in the
desired direction.
If the car has automatic transmission, ease
off the accelerator slightly and steer cau-
tiously in the desired direction.
If you get into a rear wheel skid, steer in the
same direction as the movement of the rear
of the car.
Driving with tire chains3
33 3Snow chains must only be fitted to the wheel
and tire dimensions that Saab recommends
in "Technical data" on page 285.
We recommend that you contact a Saab
dealer regarding approved tire chains. See
also page 251.
WARNING
Do not drive at speeds above 30 mph
(50 km/h) when tire chains are fitted.
Tire chains can reduce directional sta-
bility.
Do not fit tire chains to the car’s rear
wheels.
NOTECheck the links frequently for wear.
Check that the chains do not foul the
wheel arch liner at full lock.
Refer to the "Technical data" section
on page 285, for information on wheel
and tire dimensions approved for the
fitting of tire chains.

Recommendations for cars with
automatic transmissionThe following driving time limits are based
on the capacity of the cooling system in hot
weather, i.e. approximately 86°F (+30°C).
The following driving time limits are based
on the capacity of the cooling system in hot
weather, i.e. approximately 104°F (+40°C).When negotiating long hills, bear the follow-
ing important considerations in mind.
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 transmission increases:
Gear change pattern is altered
A/C compressor is switched off
Max. engine torque is reduced
The following message will be displayed on
the SID if the transmission fluid becomes
too hot:
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.
NOTEOnly use a towbar that has been
approved for your car. We recom-
mend that you entrust towbar installa-
tion to an authorized Saab dealer,
which can also provide important
information such as trailer weight.
Your authorized Saab dealer has
information on how the towbar is to be
installed and whether other measures
must be undertaken that could affect
the cooling system or other equipment
We recommend that you contact a
Saab dealer for guidance on how to
connect a trailer hitch.
Exercise care when driving on uneven
roads or against the curb if the car is
heavily laden. This particularly applies
to cars with 17" wheels.
