Traction Control
System (TCS)Anti-spin systemHow the system worksThe Traction Control System (TCS) is
designed to prevent wheelspin. This
enables the car to achieve the best possible
grip and, hence, maximum tractive effort,
together with greater stability.The TCS uses information from the ABS
wheel sensors to detect when the front (driv-
ing) wheels are rotating faster then the rear
wheels.
If the two front wheels are rotating faster
than the rear wheels, the torque from the
engine is reduced to eliminate the differ-
ence.
The process continues until all the wheels
are rotating at the same speed.
The advantages of the TCS become most
apparent when the cohesion between the
front wheels and the road surface is so low
that one or both of the wheels would lose
their grip were the car not equipped with the
TCS, e.g.:
When the car is pulling away or accelerat-
ing with the front wheels on different
surfaces (e.g. one slippery and one dry),
the TCS functions like an electronic differ-
ential lock, making sure that both wheels
rotate at the same speed. The system
also functions when the car is reversing.
When cornering, if the inside front wheel
rotates faster than the other wheels.
TCS OFF
lights up if:
a fault has been detected and the system
has therefore been switched off
there is a fault in the ABS system
the system has been switched off
manually.
WARNING
When driving normally, the TCS system
helps to improve the car’s directional
stability. The TCS must not be regarded
as a system to enable the driver to main-
tain higher speeds. The same precau-
tions must be adopted as normal for safe
cornering and driving on slippery roads.93_U S _M 07.book Page 173 W ednesday, April 12, 2006 9:30 AM

176 Starting and drivingESP
® OFF
lights up if:
a fault has been detected and the system
has therefore been switched off
the system has been switched off
manually
ESP
® indicator light
When the remote control is turned to the ON
position, the lamp is lit for about 4 seconds
while the system performs self-diagnosis.
The light comes on for a short period of
time when the ESP
® system is operative.
Operation of the ESP® indicates reduced
cohesion between the tires and the road,
and that extra care should be taken by the
driver during continued driving.
Turning ESP
® system off
The system can be turned off manually with
the ESP
® button , whereupon the
light will come on. The car must be trav-
elling slower than 35 mph (60 km/h). The
TCS is also disengaged.
The ESP® is always engaged during brak-
ing, even if it has been switched off manu-
ally with the ESP
® button.If a fault is detected in the system, the
following message will be displayed on
the SID:
The cruise control system (if active) will
automatically be disengaged if the ESP
® is
operative.
Stability control failure.
Contact service.
NOTICEChanges to the chassis, such as a
change of wheels, shock absorbers or
springs, could affect the function of the
ESP
® system.
Always consult a workshop before chang-
ing any chassis components. We recom-
mend that you contact a Saab dealer.

188 Starting and drivingTowing a trailer3Make sure you are familiar with the legal
requirements regarding speed limits for
towing, maximum trailer weights, trailer
braking requirements, and also any spe-
cial driving licence provisions.
Trailer hitch attachment3Trailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs (1588 kg),
with trailer brakes.
An electrical connection3 for the towbar
and an electrical unit are provided in the
electrical centre on the left-hand side of the
luggage compartment.
If the car has a 13-pin Saab genuine electri-
cal socket then it is possible to supply a
trailer/caravan with rear fog lights and
reversing lights. The caravan can also have
interior and exterior lighting even when the
car’s ignition is switched off. In which case,
remember not to load the battery for too
long so that it is discharged and pre-
vents the car from starting.
There is also access to power in the caravan
during a journey, the caravan battery can be
charged for example.
Also, if the car has SPA, this is deactivated
automatically if a trailer is hitched up and
correctly connected to the Saab genuine
trailer socket.
Saab recommendations:
Use a genuine Saab trailer hitch that is
designed and tested for your Saab.
Contact your Saab dealer for advice on
which trailer hitch is designed for your car.
WARNING
Do not drive with a trailer on inclines
steeper than 15 %. The load on the
drive (front) wheels will be so low that
the wheels can start to spin and
prevent further progress.
In addition, the car’s parking brake
may not always be sufficient to hold
the car and trailer securely, as the
wheels may start to slide.
Always apply the trailer’s parking
brake when unhitching it. There is
otherwise a risk of personal injury or
damage to the bumper should the
trailer start to roll.
When you hitch up the trailer be sure
to attach its safety chains to the holes
by the hitch.93_U S _M 07.book Page 188 W ednesday, April 12, 2006 9:30 AM

195 Starting and driving
Driving 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 97).
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.

196 Starting and drivingThe front towing eye is stowed by the spare
wheel. On the left-hand side of the bumper
is a cover concealing the attachment point
(tapped hole) for the towing eye.
1 Press the knob on the upper section of
this cover at the same time as pulling out
the lower edge.
2 Screw in the towing eye. The towing
eye has a left-hand thread!
3 Insert the wheel wrench into the eye to
tighten it properly.
To refit the cover: Start by inserting the top
edge of the cover. Then click in the lower
edge, one corner at a time.
Rear towing eyeThe car has a permanent towing eye at the
rear under the bumper.
If the car is equipped with a towbar, this can
be used instead of the towing eye.
Towing the carEngage neutral (automatic transmission:
move the selector lever to N). Turn on the
parking lights.
Drive carefully and do not exceed the
speed limit for vehicles on tow.NOTICENever use the towing eyes to pull the car
unstuck.

198 Starting and drivingJump starting
It 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.
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 quan-
tity makes contact with the skin, seek
medical help.
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.

219 Car careChanging bulbs
Autochecking 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 dis-
played on the SID.
Example of SID message:
The following bulbs are not checked: park-
ing lights, front fog lights, reversing lights,
license plate lighting, side marker lights and
side direction indicators.
SportCombi
The tail lights and brake lights consist of
LEDs. If approx. 3/4 of the LEDs on one side
are broken then this is indicated in the SID.
If a stop light bulb fails
Sport Sedan: 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 low 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 269.
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.

220 Car care
Xenon headlight, low beam3Xenon headlights produce roughly two
times as much light as halogen bulbs and
have a significantly longer service life.
The lamp units consist of a gas discharge
lamp containing xenon. When the lights are
switched on a very high voltage activates
the xenon gas. The lamps soon reach full
intensity.Cars with xenon headlights have automatic
levelling. The levelling system is comprised
of two sensors, one on the front suspension
and one on the rear suspension, and a
control unit by the engine bay fuse box.
Headlight alignment is adjusted automati-
cally to the car’s load to prevent dazzling
drivers in oncoming traffic.
If a fault is detected in the system, the fol-
lowing message will be displayed on the
SID:
WARNING
Xenon headlights are high tension. All
work on xenon headlights, including
changing bulbs, must be carried out by
dealer personnel.
Headlight levelling
malfunction.
We recommend you to contact a Saab
dealer to have a xenon headlight changed
