Automatic Transmission Operation
If your vehicle has an automatic transmission,
the shift lever is located on the center console
between the front seats.
There are several
different positions for
the shift lever.
PARK (P):This position locks the rear wheels.
It is the best position to use when you start the
engine because your vehicle cannot move easily.{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
use the steps that follow.
Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transmission shift lock control system.
You must fully apply your regular brakes rst
and then press the shift lever button before you
can shift from PARK (P) when the ignition key is
in RUN. If you cannot shift out of PARK (P),
ease pressure on the shift lever and push the
shift lever all the way into PARK (P) as you
maintain brake application. Then press the shift
lever button and move the shift lever into another
gear. SeeShifting Out of Park (P) on page 89.

DRIVE (D):This position is for normal driving.
It provides better fuel economy for your vehicle.
If you need more power for passing, and
you are:
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more,
push the accelerator all the way down.
The transmission will shift down to a lower
gear and have more power.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”
underLoss of Control on page 208.
Notice:If your vehicle seems to start up
rather slowly or not shift gears when you go
faster, and you continue to drive your vehicle
that way, you could damage the transmission.
Have your vehicle serviced right away. You
can drive in LOW (L) when you are driving less
than 35 mph (55 km/h) and DRIVE (D) for
higher speeds until then.
FOURTH (4):This position is also used for
normal driving. However, it reduces vehicle
speed more than DRIVE (D) without usingyour brakes. You might choose FOURTH (4)
instead of DRIVE (D) when driving on hilly,
winding roads and when going down a steep hill.
INTERMEDIATE (I):This position is also used for
normal driving. However, it reduces the vehicle’s
speed without using your brakes, for slight
downgrades where the vehicle would otherwise
accelerate due to steepness of grade. If constant
upshifting or downshifting occurs while driving on
steep hills, this position can be used to prevent
repetitive types of shifts. You might choose
INTERMEDIATE (I) instead of DRIVE (D) when
driving on hilly and winding roads.
LOW (L):This position reduces vehicle speed
more than INTERMEDIATE (I) without using your
brakes. You can use it on very steep hills, or
in deep snow or mud. If the shift lever is put in
LOW (L), the transmission will not shift into
low gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only
the accelerator pedal may damage the
transmission. If you are stuck, do not spin
the tires. When stopping on a hill, use
the brakes to hold the vehicle in place.

Anti-Lock Brake System
Warning Light
Your vehicle may have
the Anti-Lock Brake
System (ABS).
This light will come on when your engine is
started and may stay on for several seconds.
That is normal.
If the light stays on, turn the ignition off. If the
light comes on when you are driving, stop as soon
as possible and turn the ignition off. Then start
the engine again to reset the system. If the
light still stays on after driving at a speed of at
least 13 mph (20 km/h), or comes on again
while you are driving, your vehicle needs service.If the regular brake system warning light is not
on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system
warning light
is also on, you do not have anti-lock brakes and
there is a problem with your regular brakes.
SeeBrake System Warning Light on page 134.
The ABS warning light will come on briey
when you turn the ignition key to RUN. This is
normal. If the light does not come on then, have
it xed so it will be ready to warn you if there
is a problem.

Control of a Vehicle
You have three systems that make your
vehicle go where you want it to go. They are the
brakes, the steering, and the accelerator. All
three systems have to do their work at the places
where the tires meet the road.
Sometimes, as when you are driving on snow or
ice, it is easy to ask more of those control systems
than the tires and road can provide. That means
you can lose control of your vehicle. SeeTraction
Control System (TCS) on page 199and
Electronic Stability Control on page 201.
Adding non-Saturn accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 233.
Braking
SeeBrake System Warning Light on page 134.
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.
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 may 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 may 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 may take longer to stop and the brake pedal
will be harder to push.
Adding non-Saturn accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 233.Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake System
(ABS), an advanced electronic braking system
that will help prevent a braking skid.
When you start your engine and begin to drive
away, ABS will check itself. You may hear a
momentary motor or clicking noise while this test
is going on, and you may even notice that
your brake pedal moves a little. This is normal.
If there is a problem
with ABS, this warning
light will stay on.

System Warning
Light on page 135.

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, your 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 your 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 anti-lock work for you. You may
hear the anti-lock 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 called TCS that limits wheel spin. This
is especially useful in slippery road conditions.The system operates only if it senses that the rear
wheels are spinning too much or are beginning
to lose traction. When this happens, the system
works the rear 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.
SeeElectronic Stability Control (ESC)/Traction
Control System (TCS) Indicator/Warning Light
(2.0L Engine Only) on page 136for more
information.
If your vehicle is in cruise control when the
traction control system 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.
SeeTurn Signal/Multifunction Lever on page 111.

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 apply the brakes. Both
control systems — steering and braking — have
to do their work where the tires meet the road.
Unless you have four-wheel anti-lock brakes,
adding the hard braking can demand too much of
those places. You can lose control.
The same thing can happen if you are steering
through a sharp curve and you suddenly
accelerate. Those two control systems — steering
and acceleration — can overwhelm those
places where the tires meet the road and make
you lose control. SeeTraction Control System
(TCS) on page 199andElectronic Stability Control
on page 201.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
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-Saturn accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 233.
