134 Interior equipmentRearview mirrorsDoor mirrorsTo adjust
The door mirrors are electrically adjustable
and heated. The controls for adjusting the
mirrors are on the driver’s door:
1 Select a door mirror with the upper
button.
2 Adjust the mirror using the touch pad.
The mirror glass can also be adjusted man-
ually by gently pressing the glass in the
desired direction.
The mirror heating is turned on together with
the rear window heating.
If the car has an electrically adjustable
driver’s seat with memory, the mirror
settings are stored in the memory (see
page 19).Manual retraction
The door mirrors are designed to fold back
if knocked. The mirrors can also be
retracted manually. This can be useful when
parking in tight spaces, such as on the car
deck of a ferry. Remember to return the door
mirrors to their normal positions before
driving off.Reversing position
On certain model variants, the passenger-
side mirror glass can be angled down to
facilitate reversing. Press the button
shown in the illustration. This is located
under the touch pad. Return the mirror to its
normal position by pressing the button
again. The mirror will also return to its
normal position if you drive forward approx-
imately 22 yds. (20 meters).

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. It then monitors whether one driving
wheel is rotating faster than the other. If so,
the faster wheel is retarded until both
wheels are rotating at the same speed.If the two front wheels are rotating at the
same speed but are turning faster than the
rear wheels, the torque from the engine is
reduced to eliminate the difference.
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.
 When the car is pulling away or accelerat-
ing on a slippery surface, in which case
the system eliminates wheelspin. 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 under the speedometer 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.

170 Starting and drivingTCS indicatorWhen 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 under the speedometer
comes on when the TCS is operative, that is
when one of the wheels has lost its grip.
The fact that the TCS is operative indicates
that the limit for grip has been exceeded and
that the driver must exercise greater care.
Turning the TCS offThe TCS is switched on automatically when
the engine is started.
You can switch the system off manually with
the TCS button, whereupon the light
under the speedometer will come on. The
TCS cannot be switched off if the car is trav-
elling faster than 35 mph (60 km/h).
It may be necessary to switch off the system
if the car has become bogged down, for
instance. Press TCS to switch it on again.
If a fault is detected in the ABS, the TCS will
be switched off automatically.
The following message is shown on the SID:
The cruise control system (if active) will
automatically be disengaged if the TCS is
operative.

Electronic Stability
Program (ESP)Anti-skid system
(Certain variants)
The Electronic Stability Program employs
both the antilock braking system (ABS) and
the traction control system (TCS). It is a
system that helps the driver to stabilize the
car in unusual circumstances that can oth-
erwise be difficult to handle.
How the ESP system worksThe Electronic Stability Program 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 prevent the driving wheels from
spinning. The car has sensors that measure
wheel speed, yaw rate, lateral acceleration,
steering wheel position and braking pres-
sure. 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 should be engaged.
If this direction does not agree with that
intended by the driver, calculated from the
steering wheel position, the ESP is
engaged.
The ESP improves the driver’s chances
of retaining control over the car in critical
situations.
WARNING
When driving normally, the ESP system
helps to improve the car’s directional
stability. The ESP 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
must be adopted.

238 Car careUniform Tire Quality GradingQuality grades can be found where applica-
ble on the tire sidewall between tread shoul-
der and maximum section width. For exam-
ple:
Treadwear 200 Traction AA Temperature
A
The following information relates to the
system developed by the United States
National Highway Traffic Safety Administra-
tion, which grades tires by treadwear, trac-
tion and temperature performance. (This
applies only to vehicles sold in the United
States.) The grades are molded on the side-
walls of most passenger car tires. The Uni-
form Tire Quality Grading system does not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12
inches (25 to 30 cm), or to some limited-pro-
duction tires.
While the tires available on General Motors
passenger cars and light trucks may vary
with respect to these grades, they must also
conform to federal safety requirements and
additional General Motors Tire Perfor-
mance Criteria (TPC) standards.Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions on
a specified government test course. For
example, a tire graded 150 would wear one
and a half (1.5) times as well on the govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon the
actual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlled condi-
tions on specified government test surfaces
of asphalt and concrete. A tire marked C
may have poor traction performance. Warn-
ing: The traction grade assigned to this tire
is based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.Temperature – A, B, C
The temperature grades are A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the material of the tire to degenerate
and reduce tire life, and excessive temper-
ature can lead to sudden tire failure. The
grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the minimum
required by law.
Warning: The temperature grade for this tire
is established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive loading,
either separately or in combination, can
cause heat buildup and possible tire failure.

240 Car careTire Chains
Notice:
If your vehicle does not have
225/45R17 size tires, use tire chains only
where legal and only when you must.
Contact your Saab dealer regarding suit-
able snow chains. Install them on the
front tires and tighten them as tightly as
possible with the ends securely
fastened. Drive slowly and follow the
chain manufacturer’s instructions. If you
can hear the chains contacting your
vehicle, stop and retighten them. If the
contact continues, slow down until it
stops. Driving too fast or spinning the
wheels with chains on will damage your
vehicle.
If a Tire Goes FlatIt’s unusual for a tire to “blowout” while
you’re driving, especially if you maintain
your tires properly. If air goes out of a tire,
it’s much more likely to leak out slowly. But
if you should ever have a “blowout”, here are
a few tips about what to expect and what to
do:
If a front tire fails, the flat tire will create a
drag that pulls the vehicle toward that side.
Take your foot off the accelerator pedal and
grip the steering wheel firmly. Steer to main-
tain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts
much like a skid and may require the same
correction you’d use in a skid. In any rear
blowout, remove your foot from the acceler-
ator pedal. Get the vehicle under control by
steering the way you want the vehicle to go.
It may be very bumpy and noisy, but you can
still steer. Gently brake to a stop – well off
the road if possible.
If a tire goes flat, the next part shows how to
use your jacking equipment to change a flat
tire safely.
WARNING
If your vehicle has 225/45 R17 size tires,
don’t use tire chains, there’s not enough
clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause
damage to the brakes, suspension or
other vehicle parts. The area damaged by
the tire chains could cause you to lose
control of your vehicle and you or others
may be injured in a crash.
Use another type of traction device only if
its manufacturer recommends it for use
on your vehicle and tire size combination
and road conditions. Follow that manu-
facturer’s instructions. To help avoid
damage to your vehicle, drive slowly,
readjust or remove the device if it’s
contacting your vehicle, and don’t spin
your wheels.
If you do find traction devices that will fit,
install them on the front tires.
