13 Safety
Safety-belt pretensionersThe belts of the front seats are fitted with
automatic pretensioners, which are acti-
vated in the event of a severe frontal crash
or very violent rear-end crash. They serve to
reduce the forward movement of the body
by tensioning the belt.
The belt pretensioners do not activate in
less violent frontal or rear-end crashes.
Correct position for safety belt  The lap part of the belt should be pulled
as tightly as comfortable and as low as
possible across the hips, so that it is just
touching the top of the thighs. The shoul-
der belt should be well in on the shoulder
but not touching the neck.
 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. 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matically if the belt is jerked or withdrawn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.
WARNING
If the car is involved in a crash, the safety
belts, belt pretensioners and other com-
ponents must be inspected by an autho-
rized Saab dealer and replaced as neces-
sary.
Never make any alterations or repairs to
the safety belt yourself but visit an author-
ized Saab dealer.
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 (submarin-
ing) and injury can result from the lap por-
tion cutting into the abdomen.
WARNING
If two people share a belt, they risk injury
by being crushed together in the event of
a crash.

63 Instruments and controls
Central warning light
This light comes on and a chime will sound
if a fault has been detected in any system
that is critical to safety. Any of the following
can activate the central warning light and
alarm:
 Airbag system.
 Low oil pressure in engine.
 Parking brake is on (when car is moving).
 Brake fluid level low.
 Fault detected in ABS system.
 Electronic brake force distribution (distri-
bution of brake pressure between front
and rear wheels).
 Engine overheating.
 Alternator not charging properly.
Cruise Control
indicator light
The symbol is lit when cruise control is
active.
Engine malfunction
(CHECK ENGINE)
This light indicates a malfunction in the
fuel-injection or ignition system. The car
may still be driven with care and with some-
what diminished performance.
SPORT Mode Indicator
(automatic transmission)
On cars with automatic transmission the
indicator light comes on when you press the
SPORT button on the gear-lever knob.
In SPORT mode, the transmission remains
longer in the (D, 3, 2, 1) gears before
upshifting.
Cancel Sport mode by again depressing the
SPORT button; see also page 162.
WARNING
An illuminated CHECK ENGINE indicator
light indicates a serious engine-related
problem. While your car may be able to be
driven with the CHECK ENGINE indicator
light illuminated (limp-home mode), you
are advised to have your car serviced at
an authorized Saab dealer as soon as
possible.
Continued driving without this problem
being corrected might cause serious fur-
ther damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g., apply the
brakes, disengage transmission, turn off
the ignition etc.).
NOTEThe car should be checked immediately
at an authorized Saab dealer to prevent
more serious faults from arising.

159 Starting and driving
Automatic transmission
fault indicator
If the symbol appears on the main instru-
ment panel, the system has detected a fault
in the automatic transmission or its control
module (see page 64).
This also means that the Limp-home mode
has been selected, to guard against further
damage being done to the transmission. In
this mode, the automatic transmission
starts in 4th gear, and gear changes (if nec-
essary) will have to be made manually.
It is not possible to select the SPORT or
WINTER mode when the Limp-home mode
is active.
You should have the automatic transmis-
sion checked as soon as possible by an
authorized Saab dealer.
The following gears will be engaged in the
respective selector positions when the auto-
matic transmission is in the Limp-home
mode:
Overheated transmission oilIf the transmission oil becomes overheated
while driving, the following message
appears on the SID: TRANSMISSION
OVERHEATING. In this event, stop the car
in a suitable place, switch off the engine,
open the hood and wait until the message
goes out. When driving subsequent to the
transmission oil overheating, select either
3rd gear or Drive, whichever will allow the
engine to run at 3,000 rpm and maintain the
speed of traffic or a safe speed.
The transmission oil can become very hot
when the car is driven with a heavy load; for
example, driving with a trailer on hilly roads
when the wrong gear has been selected,
resulting in many extra gear changes.
Select one of the positions 1, 2 or 3. A high
outside temperature or a defective oil cooler
can also cause the oil temperature to
increase. Contact an authorized Saab
dealer, see also page 173.
Driving in hilly country with a heavy
loadOverheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a trailer in hilly country,
with the wrong gear selected, resulting in
abnormally frequent gear changing. To
avoid the transmission oil from overheating
always drive in Normal mode, then the
adaptive gear change pattern is active.
High ambient temperatures can also
increase the temperature of the transmis-
sion fluid or the oil cooler may be faulty. As
the transmission fluid temperature
increases, its useful service life is reduced.
Contact an authorized Saab dealer (see
also page 173).TowingTowing a car with automatic transmission,
see page 181. Position R D 3 2 1
Gear Reverse 4th 4th 3rd 3rd
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 4th
gear when D and 3 are selected, making
it very sluggish. To overcome this, move
the selector lever to position 1. The trans-
mission then starts in 3rd gear. When the
car is moving you can select position D
or 3.
WARNING
Remember to use engine-braking (selec-
tor position 1, 2, or 3) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!

163 Starting and driving
Cruise ControlFor 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 system is operated by means of the
controls on the stalk switch:
 OFF (system is disconnected; the system
is always in the OFF position when the
engine is started).
 ON (system switched on).
 SET/+ (to set the desired speed).
 CANCEL (cancel operation of system,
e.g. to reduce speed temporarily).
 RESUME/– (resume preset speed).
When the system is ON, the CRUISE indi-
cator light will appear on the main instru-
ment panel and will be extinguished when
the system is switched OFF. If CANCEL is
selected, CRUISE will flash off once.
To set the desired speed Move the switch to ON. Accelerate to the
desired speed (minimum speed: 25 mph
(40 km/h) and press SET/+. To increase the preset speed Accelerate to the desired speed and press
SET/+.
You can also increase the speed of the car
using the SET/+ button. Press it once to
increase the speed by 1 mph (1.6 km/h) or
hold it in and release when the desired
speed is reached.
Temporary increase in speed Press the accelerator to override the preset
speed, e.g. for overtaking.
When you release the accelerator, the
system will revert to the preset speed. To cancel temporarily Move the control stalk to CANCEL
(spring-loaded position before OFF posi-
tion). This will disengage the system but the
preset speed will be retained in the system
memory. (The memory is deleted when the
engine is switched off.) To re-engage the system To revert to the preset speed, slide the
switch to RESUME/–. This will only operate
when the car’s speed is above 25 mph
(40 km/h). To reduce the preset speedThe cruise-control system will always disen-
gage automatically the moment that either
the brake pedal or the clutch pedal is
depressed.
It is also possible to reduce the speed by:
 Sliding the button to RESUME/– once will
reduce the speed by 1 mph (1.6 km/h).
 Holding the button in the RESUME/–
position will effect a gradual reduction in
speed until the button is released.
WARNING
 Do not use the Cruise-control system
on wet or icy roads, in dense traffic or
on winding roads
 To prevent the system being activated
inadvertently, set the control to OFF
when you do not want to use the
system

164 Starting and drivingDisengaging the system The system will be disengaged:
 When the brake or clutch pedal is
depressed.
 When the switch is moved to CANCEL.
 When the switch is moved to OFF.
 When the engine is switched off.
 When the selector lever is moved to posi-
tion N (cars with automatic transmission).
BrakingTo avoid overheating the brakes, (e.g. when
negotiating long descents with a drop of
several hundred feet), select a low gear to
use the braking effect of the engine. If the
car has automatic transmission, move the
selector lever to position 1 or 2.
When driving fast, you can help to prolong
the life of the brakes by thinking ahead and
braking harder for short periods, rather than
braking more moderately over long
stretches. Brake pad wear indicatorsThe outboard brake pads on the front
wheels incorporate pad-wear indicators.
When the lining is down to 3 mm, the pad
will produce a screeching, squealing or
scraping noise when the brakes are applied.
New pads should be installed without delay.
Brake pads should only be replaced by
an authorized Saab dealer.
To ensure optimum brake performance,
it is recommended that you use only
Saab original brake pads.

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 sur-
face 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.
ProCarManuals.com

165 Starting and driving
ABS brakes ABS (Antilock Braking System) modulates
the brake pressure to the respective
wheels. Wheel sensors detect if a wheel is
about to lock, and the control module
reduces the pressure to that wheel and then
increases it once more until the tendency is
detected again.
The brake system is equipped with an Elec-
tronic Brake-force Distribution device
(EBD), which distributes the brake pressure
between the front and rear wheels in such a
way as to achieve optimum braking per-
formance irrespective of the car’s speed
and load.
The ABS system has a built-in diagnostic
function which will switch on the ABS warn-
ing light if a fault is detected in the system
(see page 62). The ABS system will not reduce the braking
distance on loose gravel or on snow or ice
but, because the wheels cannot lock up,
some steering control is retained.
When the ABS system is working, i.e. mod-
ulation of the brake pressure is in progress,
the brake pedal will pulsate and a ticking
noise will be heard. All this is perfectly nor-
mal.
Press the pedal down hard (you cannot
press too hard) and steer the car to safety. Do not release the brake pedal before the
car has come to a halt or the danger is
past!
This is critical.
If the road is slippery, the ABS system will
operate even when only light pressure is
applied to the pedal. This means that you
can brake gently to test the condition of the
road and adapt your driving accordingly.
It is well worth practising the use of ABS
brakes on a skid pad or other suitable facil-
ity.
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.

169 Starting and driving
Parking 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, trunk lid and doors,
and lubricate them with glycerol (glyc-
erin).
 After washing the car, dry the brake discs
by taking the car out on the road and
applying the brakes a few times. If the traf-
fic conditions allow, brake quite heavily
just before parking.
 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 freezing temperatures are likely to occur
during the long-term parking, remove the
battery and store it away from freezing
temperatures.
 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 which will not breath.

1Pointing downhill and
against the curb
– Turn the wheels into the
curb and edge the car for-
ward until the wheels touch
the curb. 2Pointing uphill and
against the curb
– Turn the wheels away
from the curb and edge the
car back until the wheels
touch the curb. 3Pointing uphill or down-
hill – no curb
– Turn the wheels towards
the edge of the road. If the
car should start rolling, it
will not run into the road.

170 Starting and drivingEconomical motoringFactors affecting fuel consumption Fuel consumption is greatly affected by the
general driving conditions, the way in which
the car is driven and at what speeds, the
weather, the state of the road, the condition
of the car, etc. Breaking-in Fuel consumption may be somewhat higher
during the break-in period (the first 3,000–
4,000 miles (5,000–7,000 km). Weather conditionsFuel consumption can be as much as 10 %
lower in summer than in winter. The higher
consumption in cold weather is explained by
the longer time it takes for the engine to
reach normal operating temperature, and
for the transmission and wheel bearings to
warm up. Fuel economy is also affected by
the distance driven: short journeys of
3-5 miles (5-8 km) do not give the engine
enough time to reach normal temperature.
Strong winds can also affect fuel consump-
tion. How to read the graph:
If fuel consumption with the engine at
normal temperature is 28 mpg
(10l/100 km), the actual fuel consumption 3
miles (5 km) after the engine has started
from cold will be:
– 23.5 mpg (12l/100 km) at outside temp.
of 68°F (20°C) (increase of 20%)
– 17.7 mpg (16l/100 km) at outside temp.
of 32°F (0°C) (increase of 60%)
– 14 mpg (20l/100 km)) at outside temp. of
–4°F (–20°C) (increase of 100%)
As can be seen, both the distance travelled
by the car and the outside temperature have
a major impact on fuel consumption after the engine has started from cold. Thus, if the
car is mainly used for short journeys of
3–5 miles (5–8 km), the fuel consumption
will be 60–80 % higher than normal.
Driving technique To obtain the best running economy, not
only regarding fuel consumption but gen-
eral wear also, regular service is required.
 High speed, unnecessary acceleration,
heavy braking and much low gear work all
gives rise to higher fuel consumption.
 Frequent gear changing in traffic, starting
in cold weather, the use of studded tires
and roof racks, and towing a trailer all
increase fuel consumption.
 Do not run the engine when the car is sta-
tionary.
If idling, it will take much longer before the
engine becomes hot. Engine wear is
greatest during this warming-up phase.
Therefore drive away as soon as possible
after the engine is started and avoid high
revving.
WARNING
Never switch the engine off while driving
as the effect of the brakes and power
steering will be greatly reduced.
