170 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

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.

173 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 82).
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 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.
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.

177 Starting and driving
Electronic Stability
Program ESP
®
Anti-skid system
The ESP
® system employs both the
antilock braking system (ABS) and the trac-
tion control system (TCS). It is a system that
helps the driver to stabilize the car in
unusual circumstances that can otherwise
be more difficult to handle.
How the ESP
® system works
The ESP
® system can help to prevent the
car from skidding by braking one or several
wheels independently of the driver. The
engine output is then also reduced to pre-
vent the driving wheels from spinning. The
car has sensors that measure wheel speed,
yaw rate, lateral acceleration, steering
wheel position and braking pressure. The
values provided by these sensors are used
to calculate the actual direction of the car,
the intentions of the driver and whether the
ESP
® system should be engaged.
If this direction does not agree with that
intended by the driver, calculated from the
steering wheel position, the ESP
® system is
engaged.
The ESP
® system improves the driver’s
chances of retaining control over the car in
a critical situation.
WARNING
When driving normally, the ESP
® system
helps to improve the car’s stability and
maneuverability under slippery road and
extreme driving conditions. The ESP
®
system must not be regarded as a system
to enable the driver to maintain higher
speeds. The same precautions must be
adopted as normal for safe cornering and
driving on slippery roads must be
adopted.

brakes on one or several wheels in order
to reduce the likelihood of the car skidding

179 Starting and driving
Parking brakeThe parking brake lever is situated between
the front seats. The brake acts on the rear
wheels. When the parking brake is applied,
the indicator light on the main instru-
ment panel will come on.
To release the parking brake, lift the lever
slightly, pull the release button on the under-
side of the lever and lower the lever.If conditions allow, it is best if the brake
pedal is not depressed, or only depressed
as little as necessary so as to stop the car
from rolling, when the parking brake is
applied.
To facilitate releasing the parking brake,
depress the brake pedal. This is especially
appropriate if the car is standing on a hill.
If the parking brake is applied when the car
starts off, the following message will appear
on the SID:
Parking
WARNING
Always apply the parking brake when
you park the car. If the car is to be
left parked for a long time, refer to
page 181.
Always apply the parking brake
before removing the remote control.
Do not use the parking brake while
driving.
Grasp the parking brake lever in such
a way that no fingers get trapped when
you release the parking brake.
Release park brake.
WARNING
Never leave children or pets unat-
tended in the car. In warm, sunny
weather, the temperature inside the
car can reach 160–180°F (70–80°C).
Park where the vehicle will not create
an obstruction or a hazard to other
road users.
Do not park on dry grass or other com-
bustible material. The catalytic con-
verter gets very hot and could start a
fire.
Apply the parking brake, remove the
remote control and lock the car.

Assistance3
33 3Saab Parking Assistance
Saab Parking Assistance facilitates parking
and reversing. There are four sensors in the
rear bumper that detect objects up to 6 ft
(1.8 meters) behind the car.
If the car is heavily laden, the system may
falsely indicate that there is an object within
the detection range. This is since the sen-
sors are angled towards the ground when
the car is tail-heavy.The system uses four sensors in the rear
bumper. These emit ultrasound signals that
bounce back to the sensors off any objects
behind the car. The system, however,
cannot always detect small or narrow
objects, such as a post, since the surface
area presented to the car is too small.The system is activated automatically when
reverse is engaged or selected. Audible
confirmation is given and the following text
is shown on the SID:
If a warning message, such as the safety-
belt reminder, is shown on the SID when
reverse is engaged, the audible signals
from the parking assistance system will not
be heard since the warning message has
priority.
When the sensors detect an object within
the monitored area, pulses of sound (- - - -)
will be heard. The frequency of these pulses
WARNING
Responsibility always lies with the driver
when reversing.
The parking assistance system can
facilitate parking and reversing.
Bear in mind that small objects, such
as a child lying on the ground, and
narrow objects cannot always be
detected by the system.

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.

192 Starting and drivingWhen continuing your journey, manually
select a low gear in which the engine speed
is about 3,500 rpm until the incline eases
(see page 170).
Recommendations for cars with
manual transmissionRises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
When the needle is just outside the red
zone, the A/C compressor will be switched
off and, on certain engine variants, the max-
imum engine torque will be limited.
When continuing your journey, select a low
gear in which the engine speed is about
3,500 rpm until the incline eases.
Trailer hitch loadThe weight distribution on the trailer makes
a lot of difference to the handling properties
of the car and trailer combination. With a
two-wheel trailer, concentrate the load over
the wheels and keep it as low as possible.
The trailer should be loaded so that the load
on the towball is 110–165 lbs. (50–75 kg).
Note that this load must be included in the
total load for the car. If this now exceeds the
specified load capacity, the load in the trunk
may have to be reduced by the correspond-
ing amount.
WARNING
Remember to use engine-braking (selec-
tor position M1, M2, or M3) to spare the
brakes when you are driving on a long or
steep downhill slope.
Overheating can cause the brakes to
fade!

Fitting roof carriers3
33 3SportCombi with roof rails
1 Clean the car’s roof rails.
2 Check the markings on the cross
members to see which is the front and
which is the rear roof carrier.
3 Place the cross members on the roof
rails, on their respective sides of the
centre supports. The cross members
must not be placed beyond the front or
rear joint on the rail. Ensure that the
distance between the cross members is
at least 700 mm (27.6 in.).
If a roof box is to be fitted, the cross
members must be positioned so that the
tailgate can be opened fully without
hitting the roof box.4Using your thumb, press the bracket
so that it lies snugly against the
outside of the roof rail. Make sure that
the roof carriers are seated centrally on
the rubber spacers and that these sit
correctly on the roof rail. Pull the spacers
down slightly on the inside of the roof
rail.
5 Centre the roof carriers so that they
protrude equally on both sides.6 Tighten the roof carriers by hand.
Ensure that the tightening knobs are
upright once the roof carriers have been
tightened.
7 Make sure the roof carriers are securely
in place.93_US_M08.book Page 195 Friday, May 11, 2007 11:37 AM
