53 Instruments and controls
Automatic transmission,
fault indicator
On a car with an automatic transmission,
this warning symbol is illuminated if a fault
has been detected in the transmission.
Switch the ignition off and on again to check
if the fault persists.
Even if the fault persists, it is still possible in
most cases to drive the car (see page 161).
Have the automatic transmission checked
by an authorized Saab dealer as soon as
possible.
Traction-control-system:
OFF
The indicator light goes on when the Trac-
tion Control System is switched off with the
TCS OFF button.
IMPORTANT: the Traction Control System
is automatically engaged every time the
engine is started (see page 169).
The indicator light also goes on when there
is a fault in the Traction Control System. In
this case the light cannot be turned off by
means of the TCS button. If a fault is indi-
cated, have the system checked by an
authorized Saab dealer.
See also ”Traction Control System”, on
page 169.
TCS modulation in
progress
The TCS indicator light is located in the
lower half of the tachometer and will be illu-
minated when TCS regulation is occurring,
i.e. when there is insufficient traction
between the tires and the road surface to
provide the grip required for the accelera-
tion called for. The driver can also sense
that the engine is not responding normally to
the accelerator.
Operation of the TCS indicates reduced
traction between the tires and the road, and
that extra care should be taken by the driver.
In normal driving, the TCS will improve both
ride comfort and safety, but must not be
regarded as a system to enable the driver to
drive at or maintain a higher rate of speed.
The same precautions for safe cornering
and driving on slippery roads must still be
applied (see page 169).
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 4th
gear when D is selected, making it very
sluggish. To overcome this, select posi-
tion 2 to prevent unnecessary wear on the
transmission. The transmission then
starts in 3rd gear. When the car is moving
you can select position D or 3.
When the indicator light is on, the car
must not be driven with a trailer attached.

169 Starting and driving
Traction Control SystemHow the system works The 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 system uses information from the
ABS system’s wheel sensors to detect
when the front (driving) 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 system 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 sur-
faces (e.g. one slippery and one dry). The
TCS then functions like an electronic dif-
ferential lock.
 When the car is pulling away or accelerat-
ing on a slippery road, in which case the
TCS eliminates wheelspin. The same
applies when the car is reversing.
 On cornering, if there is a tendency for the
inner front wheel to rotate faster than the
other wheels.
 On overtaking.
TCS OFF The TCS OFF indicator on the main instru-
ment panel will come on:
 If a fault has been detected and the
system has therefore been switched off.
 If there is a fault in the ABS system.
 If the system has been switched off man-
ually.
The indicator light will also come on for
4 seconds when the ignition key is turned to
ON, while an internal system check is per-
formed. TCS indicator The indicator light will come on for
4 seconds when the ignition key is turned to
ON, while an internal system check is per-
formed.
The TCS light in the tachometer comes on
when the system is operative, i.e. when the
wheels are not rotating at the same speed.
The fact that the TCS system is operative
indicates that the limit for grip has been
exceeded and that the driver must exert
greater care.
WARNING
In normal driving, the TCS system
enhances the safety of the car, but it does
not mean that the car can be driven faster.
The same care and prudence normally
applied should be displayed on cornering
and when driving on slippery roads.

223 Car care and technical information
Uniform Tire Quality Grading (US)Quality 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 ATreadwearThe 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 one half (1 1/2) times as well on the gov-
ernment course as a tire graded 100. The
relative 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
practices and differences in road character-
istics and climate.
TractionThe traction grades, from highest to lowest,
are AA, A, B and C. These grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
Wear indicatorsThe tires incorporate wear indicators in the
form of smooth, treadless strips across the
width, which become visible when only
1.6 mm of tread remains. As soon as the
indicators become visible, new tires should
be fitted without delay.
Make sure you are familiar with the legal
limit for minimum tread depth in your
country and also any regulations gov-
erning the use of winter tires.
WARNING
The traction grade assigned to a tire is
based on straight-ahead braking, traction
test and does not include acceleration,
cornering, hydroplaning or peak traction
characteristics.
