2008 SAAB 9-3 traction control

124 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 20).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 position3
33 3
On certain model variants, the passen-
ger-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.
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:
the system has been switched off
manually. It cannot be switched off if the
car is travelling faster than 35 mph
(60 km/h).
there is a fault in the ABS system
a fault has been detected and the system
has therefore been switched off and at the
same time the following message is
shown on the SID:
WARNING
When driving normally, the TCS system
helps to improve the car’s stability,
maneuverability and traction under slip-
pery road and extreme driving conditions.
The TCS 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 cor-
nering and driving on slippery roads.
Traction control failure.

249 Car care
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.
Wheel Alignment and Tire
BalanceThe wheels on your vehicle were aligned
and balanced carefully at the factory to give
you the longest tire life and best overall per-
formance.
Scheduled wheel alignment and wheel bal-
ancing are not needed. However, if you
notice unusual tire wear or your vehicle pull-
ing one way or the other, the alignment may
need to be reset. If you notice your vehicle
vibrating when driving on a smooth road,
your wheels may need to be rebalanced.

251 Car care
Tire Chains
Notice: If your vehicle does not have
235/45R17 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 235/45 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 con-
tacting your vehicle, and don’t spin your
wheels.
If you do find traction devices that will fit,
install them on the front tires.93_US_M08.book Page 251 Friday, May 11, 2007 11:37 AM
