2008 SATURN AURA Owners Manual

Police records show that almost 40 percent of all motor
vehicle-related deaths involve alcohol. In most cases,
these deaths are the result of someone who was
drinking and driving. In recent years, more than
17,000 annual motor vehicle-related deaths have been
associated with the use of alcohol, with about
250,000 people injured.
For persons under 21, it is against the law in every
U.S. state to drink alcohol. There are good medical,
psychological, and developmental reasons for
these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink alcohol and
then drive.
Medical research shows that alcohol in a person’s
system can make crash injuries worse, especially
injuries to the brain, spinal cord, or heart. This means
that when anyone who has been drinking — driver
or passenger — is in a crash, that person’s chance of
being killed or permanently disabled is higher than if the
person had not been drinking.Control of a Vehicle
The following three systems help to control your vehicle
while driving — brakes, steering, and accelerator. At
times, as when driving on snow or ice, it is easy to ask
more of those control systems than the tires and road can
provide. Meaning, you can lose control of your vehicle.
SeeTraction Control System (TCS) on page 4-6and
Electronic Stability Control (ESC) on page 4-8.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.
Braking
SeeBrake System Warning Light on page 3-32.
Braking action involves perception time and reaction
time. First, you have to decide to push on the brake
pedal. That is perception time. Then you have to bring
up your foot and do it. That is reaction time.
4-3

Average reaction time is about three-fourths of a second.
But that is only an average. It might be less with one
driver and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination,
and eyesight all play a part. So do alcohol, drugs, and
frustration. But even in three-fourths of a second, a
vehicle moving at 60 mph (100 km/h) travels 66 feet
(20 m). That could be a lot of distance in an emergency,
so keeping enough space between your vehicle and
others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement
or gravel; the condition of the road, whether it is
wet, dry, or icy; tire tread; the condition of the brakes;
the weight of the vehicle; and the amount of brake force
applied.
Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is a
mistake. The brakes might not have time to cool between
hard stops. The brakes will wear out much faster if you do
a lot of heavy braking. If you keep pace with the traffic
and allow realistic following distances, you will eliminate a
lot of unnecessary braking. That means better braking
and longer brake life.If your vehicle’s engine ever stops while you are driving,
brake normally but do not pump the brakes. If you do,
the pedal could get harder to push down. If the
engine stops, you will still have some power brake
assist. But you will use it when you brake. Once the
power assist is used up, it can take longer to stop and
the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.
Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS),
an advanced electronic braking system that will
help prevent a braking skid.
When you start the engine and begin to drive away,
ABS will check itself. You might hear a momentary
motor or clicking noise while this test is going on, and
you might even notice that the brake pedal moves
a little. This is normal.

If there is a problem with
ABS, this warning light will
stay on. SeeAntilock
Brake System Warning
Light on page 3-33.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.
As you brake, the computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.Remember: ABS does not change the time you need to
get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle
in front of you, you will not have time to apply the brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work for you. You might hear
the antilock pump or motor operate, and feel the
brake pedal pulsate, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same time.
In many emergencies, steering can help you more than
even the very best braking.

Traction Control System (TCS)
Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that the front wheels are spinning too much
or are beginning to lose traction. When this happens, the
system works the front brakes and reduces engine
power by closing the throttle and managing engine spark
to limit wheel spin.
This light will ash when
your traction control
system is limiting
wheel spin.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when TCS begins to
limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may re-engage the cruise control.
SeeCruise Control on page 3-10.When this light is on solid
and either the SERVICE
TRACTION or TRACTION
OFF message is
displayed, the system will
not limit wheel spin.
Adjust your driving accordingly. SeeDIC Warnings and
Messages on page 3-46for more information.
The Traction Control System is automatically enabled
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system enabled. You can turn TCS
off if you ever need to.
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 want to “rock” your vehicle
to 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 4-21.

ProCarManuals.com

To turn the system off or
on, press and release this
button located on the
instrument panel.
The DIC will display the appropriate message as
described previously when you press the button.
Traction Control Operation
Traction control limits wheel spin by reducing engine
power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when you start your vehicle, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses either of the front wheels are
spinning or beginning to lose traction while driving. For
more information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-43.
Notice:If you allow the wheel(s) of one axle
to spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC
and/or SERVICE TRACTION messages are
displayed, you could damage the differential.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.
Notice:When traction control is turned off, it is
possible to lose traction. If you attempt to shift with
the front wheels spinning with a loss of traction,
it is possible to cause damage to the transmission.
Do not attempt to shift when the front wheels do
not have traction. Damage caused by misuse of the
vehicle is not covered. See your warranty book
for additional information.
The traction control system 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 ESC/TCS light will ash and the cruise
control will automatically disengage. When road
conditions allow you to use cruise control again,
you may re-engage the cruise control. SeeCruise
Control on page 3-10.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.

Electronic Stability Control (ESC)
Your vehicle may have an Electronic Stability
Control (ESC) system which combines antilock brake,
traction and stability control systems and helps the
driver maintain directional control of the vehicle in
most driving conditions.
When you rst start your vehicle and begin to drive away,
the system performs several diagnostic checks to ensure
there are no problems. You may hear or feel the system
working. This is normal and does not mean there is a
problem with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h).
If the system fails to turn on or activate, the ESC/TCS
light will be on solid, and the ESC OFF or SERVICE
ESC message will be displayed.
For more information, seeDriver Information
Center (DIC) on page 3-43.This light will ash on the
instrument panel cluster
when the ESC system
is both on and activated.
You may also feel or hear the system working; this
is normal.
When the light is on solid and either the SERVICE ESC
or ESC OFF message is displayed, the system will
not assist the driver in maintaining directional control of
the vehicle. Adjust your driving accordingly. SeeDIC
Warnings and Messages on page 3-46.
The Electronic Stability Control (ESC) system is
automatically enabled whenever you start your vehicle.
To assist the driver with vehicle directional control,
especially in slippery road conditions, you should always
leave the system on. But, you can turn ESC off if you
ever need to.
4-8
ProCarManuals.com

If the vehicle is in cruise control when the system
begins to assist the driver maintain directional control
of the vehicle, the ESC/TCS light will ash and the
cruise control will automatically disengage. When road
conditions allow you to use cruise again, you may
re-engage the cruise control. SeeCruise Control
on page 3-10.
The ESC/TCS button
is located on the
center console.
The traction control system can be turned off or back on
by pressing the ESC/TCS button. To disable both traction
control and ESC, press and hold the button briey.
When the ESC system is turned off, the TRACTION
OFF and ESC OFF messages will appear, and
the ESC/TCS light will be on solid to warn the driver
that both traction control and ESC are disabled.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 want to “rock” your vehicle
to 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 4-21.
ESC may also turn off automatically if it determines that
a problem exists with the system. The ESC OFF and
SERVICE ESC messages and the ESC/TCS light will
be on solid to warn the driver that ESC is disabled and
requires service. If the problem does not clear after
restarting the vehicle, you should see your dealer/retailer
for service. SeeDIC Warnings and Messages on
page 3-46for more information.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.

Steering
If the engine stalls while you are driving, the power
steering assist system will continue to operate until you
are able to stop your vehicle. If you lose power steering
assist because the electric power steering system is not
functioning, you can steer, but it will take more effort.
If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time,
you may notice a reduced amount of power steering
assist. The normal amount of power steering assist
should return shortly after a few normal steering
movements.
The electric power steering system does not require
regular maintenance. If you suspect steering system
problems, contact your dealer/retailer for service repairs.
SeeDIC Warnings and Messages on page 3-46.
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 the 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. SeeTraction Control
System (TCS) on page 4-6andElectronic Stability
Control (ESC) on page 4-8.
What should you do if this ever happens? Ease up on
the brake or 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 the
front wheels are straight ahead.
