13 Safety
Correct position for safety beltConsider this:
 Position the lap strap snugly and low
across the hips so that it just touches the
thighs.
The shoulder strap must be as far in on
the shoulder as possible.
 Check to ensure that the belt is not twisted
or rubbing against any sharp edges.
 There should not be any slack in the belt.
Pull the belt tight – particularly important
when thick outer clothing is worn. It is advisable to remove thick items of
clothing.
 Refrain from tilting the backrest more than
necessary, as the safety belt provides
better protection when the seat is in the
more upright position.
 Only one person per safety belt!
 For most of the time a safety belt is worn,
the retractor will allow the wearer freedom
of movement. The retractor locks up auto-
matically if the belt is jerked or withdrawn
sharply, the car tilts, the brakes are
applied hard or a crash occurs.
 Children up to 6 years of age must always
be seated in a child seat. Saab recom-
mends the use of a child seat for children
up to the age of 10.
 Children who have grown out of a child
seat should be restrained by the car’s
standard three-point belts. Make sure that
the shoulder belt is not in contact with the
neck or throat. If it is, a booster seat/cush-
ion may be necessary.
WARNING
Proper positioning of the safety belt is
extremely important.
 An out of position safety belt can result
in the wearer sliding underneath the
belt in a crash (submarining) and
injury can result from the lap portion
cutting into the abdomen.
Never fasten the safety belt with the
shoulder belt behind the body or pull
the belt off the shoulder and under the
arm.
 Two people must never share one
safety belt. In the event of a crash
those sharing a belt risk being crushed
together and injured.

175 Starting and driving
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 205.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 178).
Limp-homeIf the transmission malfunctions, the control
module will activate limp-home mode. Driv-
ability will be affected to varying degrees.
The following message is shown on the SID:
In this mode, only 2nd and 5th gears are
available. Select 2nd gear when driving at
low speeds and 5th gear at higher speeds.
2nd gear must be selected manually. Select
5th gear manually or move the selector
lever to D (see page 178).
Cars with 5-speed transmission
In this mode, only 2nd and 5th gears are
available. Select 2nd gear when driving at
low speeds and 5th gear at higher speeds.
2nd gear must be selected manually. Select
5th gear manually or move the selector
lever to D, see page 178.
Cars with 6-speed transmission3
 The car may be totally powerless. If this is
case, have the car transported to a work-
shop to have the problem rectified.
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!
NOTICEDo not tow a trailer if limp-home mode is
engaged.
Gearbox malfunction.
Limited performance.
Contact Saab dealer.

178 Starting and driving
Certain variants also have steering wheel controls for manual gear
selection. On these models, it is possible to change gear manually
using the selector lever and the steering wheel controls. The steer-
ing wheel controls are only active when the selector lever is in the M
position.
Select a higher gear by pressing the right-hand button and a lower
gear by pressing the left-hand button. Sentronic, manual gear selection
Move the selector lever to the manual position (M)
(to the left position D) to select gear manually.
Select a higher gear by pressing the selector lever
forward or a lower gear by pulling it back. The
selector lever will return to a position adjacent to
the letter M after each gear change.
An example of when you may wish to make
manual gear changes is when overtaking, to
enable you to remain in a low gear for an extended
period of time.
If the road surface is slippery, you may wish to start
off in 2nd or 3rd to reduce the risk of wheel spin.
When descending steep hills you should select a
low gear to increase the braking effect of the
engine and thus spare the brakes.
Manual gear selections are displayed on the main instrument
panel. The letter M and the current gear are displayed.
When the selector lever is in the M position, as opposed to the D
position, the engine is much more responsive to changes in accel-
erator position. The accelerator has a different feel.
When changing down, the desired gear can be selected but the
transmission will not change down until the engine speed is low
enough to avoid overrevving.Steering wheel controls for manual gear

179 Starting and driving
Cruise control(Cruise control system)
For safety reasons (brake system func-
tion), the brakes must be applied once
when the engine has started, before the
cruise control system can be activated.
The following message is shown on the SID:
The system has the following functions:
1 ON: engaged
2 OFF: disengaged
3 SET/+: sets the speed and increases
the set speed
4 SET/ –: sets the speed and decreases
the set speed
5 RESUME: re-engages the system at the
set speed
The CRUISE indicator light in the main
instrument panel comes on when the switch
is slid to ON. If you switch off the engine
while the cruise control is ON, the system
will be ON the next time the engine is
started.
To set the desired speed1 Slide the switch to ON.
2 Move the thumbwheel up to SET/+ or
SET/– when the car has reached the
desired speed (above 15 mph (25 km/
h)).To increase the preset speedYou can increase the speed in any of
the following ways:
 Accelerate to the desired speed. Jog the
control to SET/+ or SET/–.
 Jog the control to SET/+ to increase the
speed by 1 mph (1.6 km/h) (when cruise
control already engaged).
 Hold the control in the SET/+ position until
the desired speed is reached (when
cruise control already engaged).
WARNING
Do not use the cruise control system in
wet or icy conditions, in dense traffic or on
winding roads.
Tap brakes lightly before
using cruise control.

180 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.

181 Starting and driving
ABS brakesThe Antilock Braking System (ABS) modu-
lates the brake pressure to each wheel. The
pressure is automatically reduced just
before the wheel locks up and then
increases again to the point at which the
wheel is just about to lock. The wheel sen-
sors send information to the brake system’s
electronic control module for every 4 or so
inches (decimetre) that the car rolls. This
information is processed continuously to
ensure that the adjustment of the brake
pressure will be as exact as possible.
Adjustment takes place up to 12 times per
second.The brake system provides Electronic
Brakeforce Distribution (EBD). This distri-
butes the brake pressure between the front
and rear wheels, in such a way as to achieve
optimum braking performance irrespective
of the car’s speed or load.
The ABS has a built-in diagnostics function
which will switch on the ABS warning light
if a fault is detected in the system (see
page 84).
The following message will appear on the
SID (and corresponding symbol on main
instrument unit) if a fault is detected:
WARNING
 It is prudent to try your brakes from
time to time, especially when driving in
heavy rain, through water collected on
the road, in snow, on a wet road
surface or in salty slush. In such condi-
tions, the brakes may take longer than
normal to take effect. To rectify this,
touch the brake pedal periodically to
dry the brakes out.
 The same applies after the car has
been washed or when the weather is
very humid.
 Avoid parking the car with wet brakes.
Before parking, and if the traffic condi-
tions allow, brake quite heavily so that
the brake discs and pads warm up and
dry.
 The brakes are power assisted and it
should be kept in mind that the servo
unit only provides the power assis-
tance when the engine is running.
 The brake pressure required when the
engine is off, (e.g. when the car is
being towed) is roughly four times the
normal pedal force required. The
pedal also feels hard and unrespon-
sive.
 Overheating can cause the brakes to
fade!
WARNING
 The additional safety afforded by the
ABS system is not designed to allow
drivers to drive faster but to make
normal driving safer.
 To stop as quickly as possible, without
loss of directional stability, whether
the road surface is dry, wet or slippery,
press the brake pedal down hard
without letting up (do not pump the
pedal), declutching simulta-
neously, and steer the car to safety.
Antilock brake malfunction.
Contact Saab dealer.

182 Starting and drivingThe ABS system will not reduce the braking
distance on loose gravel, snow or ice but,
because the wheels cannot lock up, steer-
ing control is retained.
When the ABS system operates you will feel
the brake pedal pulsate and hear a ticking
noise, both of which are perfectly normal.
Apply the brake pedal with full force (you
cannot press too hard), declutch and if nec-
essary steer to safety.
Do not release the brake pedal before the
car has come to a halt or the danger is
past!
The above is critical.
If the road is slippery, the ABS system will
operate even when only light pressure is
applied to the brake pedal. This means that
the driver can brake gently to test the condi-
tion of the road and adapt their driving
accordingly.
It is well worth practising the use of ABS
brakes on a skid pan or other suitable
facility.
