Traction Control Off
In this mode, stability control and brake-traction control
are functional. Engine speed management will be
modied and the driven wheels can spin more freely.
This can cause the brake-traction control to activate more
frequently. If the controller detects excessive wheel spin
in this mode, the StabiliTrak
®indicator light may blink and
the STABILITRAK ACTIVE message may be displayed
to warn the driver that damage may occur to the
transfer case.

StabiliTrak®Off
In this mode, both stability control and part of the
traction control system are disabled. Your vehicle will
still have brake-traction control, but will not be able
to use the engine speed management system. You may
still hear system noises as a result of the brake-traction
control coming on. If the controller detects excessive
wheel spin in this mode, the StabiliTrak
®indicator light
may blink and the STABILITRAK ACTIVE message
may be displayed to warn the driver that damage may
occur to the transfer case.It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn the
system off if your vehicle is stuck in sand, mud, ice or
snow, and you may want to “rock” your vehicle in an
attempt to free it. It may also be necessary to turn off the
system when driving in extreme off-road conditions where
high wheel spin is required. SeeIf Your Vehicle is Stuck
in Sand, Mud, Ice or Snow on page 4-32for more
information.

Notice:If the StabiliTrak®light comes on due to
heavy braking and/or because the traction control
system has been continuously active, do not allow
the wheel(s) of one axle to spin excessively. If you
do, you may be causing damage to the transfer case.
This could lead to costly repairs not covered by your
warranty.
Notice:If you allow the wheel(s) of one axle to spin
excessively while the StabiliTrak
®, ABS and brake
warning lights and the SERVICE STABILITRAK
message are displayed, you could damage the
transfer case. The repairs would not be covered by
your warranty. Reduce engine power and do not spin
the wheel(s) excessively while these lights and this
message are displayed.
StabiliTrak
®may activate on dry or rough roads or under
conditions such as heavy acceleration while turning or
abrupt upshifts/downshifts of the transmission. When this
happens, you may notice a reduction in acceleration, or
may hear a noise or vibration. This is normal.
If your vehicle is in cruise control when the system
activates, the StabiliTrak
®light will blink, and the
cruise control will automatically disengage. When road
conditions allow, you may re-engage the cruise control.
SeeCruise Control on page 3-11.StabiliTrak
®will turn off automatically if a problem is
detected in the system. The StabiliTrak®light will come
on and SERVICE STABILITRAK will be displayed on
the DIC. For vehicles without a DIC, the StabiliTrak
®
light and the StabiliTrak®service light will both come on.
If the SERVICE STABILITRAK message (or StabiliTrak®
service light) does not clear itself after restarting the
vehicle, you should see your dealer for service.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3for more information.
All-Wheel Drive (AWD) System
Your vehicle has this feature. There is no lever or switch
to engage or disengage the front axle. It is fully automatic
and adjusts as needed for road conditions. Your vehicle
has an active transfer case allowing two-wheel-drive
operation on dry roads. The transfer case will shift
automatically into all-wheel drive on slippery surfaces.
You may feel an extra shift when the all-wheel drive
engages.

Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer
but it will take much more effort.
Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject
to the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when you
turn the front wheels. If there is no traction, inertia will
keep the vehicle going in the same direction. If you
have ever tried to steer a vehicle on wet ice, you will
understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle
at which the curve is banked, and your speed. While you
are in a curve, speed is the one factor you can control.Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to do their
work where the tires meet the road. Adding the sudden
acceleration can demand too much of those places. You
can lose control.
What should you do if this ever happens? Ease up
on the accelerator pedal, steer the vehicle the way you
want it to go, and slow down.
Speed limit signs near curves warn that you should adjust
your speed. Of course, the posted speeds are based on
good weather and road conditions. Under less favorable
conditions you will want to go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
Adding non-Saab accessories can affect your vehicle’s
performance. SeeAccessories and Modications on
page 5-3.

Loss of Control
Let us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough friction
where the tires meet the road to do what the driver has
asked.
In any emergency, do not give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.
The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, your wheels
are not rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to
slip and lose cornering force. And in the acceleration
skid, too much throttle causes the driving wheels to spin.
A cornering skid is best handled by easing your foot
off the accelerator pedal.If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you
will want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer
and vehicle control more limited.
While driving on a surface with reduced traction, try your
best to avoid sudden steering, acceleration, or braking,
including engine braking by shifting to a lower gear. Any
sudden changes could cause the tires to slide. You may
not realize the surface is slippery until your vehicle is
skidding. Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to make
a mirrored surface — and slow down when you have
any doubt.
Remember: Any Anti-Lock Brake System (ABS) helps
avoid only the braking skid.

Buying New Tires
The original equipment tires installed on your vehicle,
when it was new, were designed to meet the Tire
Performance Criteria Specication (TPC spec) system
rating. If you need replacement tires, Saab strongly
recommends that you get tires with the same TPC Spec
rating. This way, your vehicle will continue to have tires
that are designed to give the same performance and
vehicle safety, during normal use, as the original tires.
The exclusive TPC Spec system considers over a dozen
critical specications that impact the overall performance
of your vehicle, including brake system performance,
ride and handling, traction control, and tire pressure
monitoring performance. The TPC Spec number is
molded onto the tire’s sidewall by the tire manufacturer.
If the tires have an all-season tread design, the TPC spec
number will be followed by a MS, for mud and snow.
SeeTire Sidewall Labeling on page 5-57for additional
information.{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes,
brands, or types (radial and bias-belted tires)
the vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes, brands, or types may also cause damage
to your vehicle. Be sure to use the correct size,
brand, and type of tires on your vehicle’s
wheels.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.
5-67
ProCarManuals.com

If you must replace your vehicle’s tires with those that do
not have a TPC Spec number, make sure they are the
same size, load range, speed rating, and construction
type (radial and bias-belted tires) as your vehicle’s
original tires.
Your vehicle’s original equipment tires are listed on the
Tire and Loading Information Label. This label is attached
to the vehicle’s center pillar (B-pillar). SeeLoading Your
Vehicle on page 4-33, for more information about the Tire
and Loading Information Label.
Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may affect
the way your vehicle performs, including its braking, ride
and handling characteristics, stability, and resistance
to rollover. Additionally, if your vehicle has electronic
systems such as, antilock brakes; traction control; and
stability control, the performance of these systems can
be affected.
{CAUTION:
If you add different sized wheels, your vehicle
may not provide an acceptable level of
performance and safety if tires not
recommended for those wheels are selected.
You may increase the chance that you will
crash and suffer serious injury. Only use Saab
specic wheel and tire systems developed for
your vehicle, and have them properly installed
by a Saab certied technician.

Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system developed
by the United States National Highway Traffic Safety
Administration, which grades tires by treadwear, traction
and temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car tires.
The Uniform 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-production tires.
While the tires available may vary with respect to
these grades, they must also conform to federal safety
requirements.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specied government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course
as a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from the norm
due to variations in driving habits, service practices,
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 represent the tire’s ability to stop on
wet pavement as measured under controlled conditions
on specied government test surfaces of asphalt and
concrete. A tire marked C may have poor traction
performance. Warning: 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.
