engine SATURN SKY 2007 Service Manual

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.

When the system is on,
this warning light will
come on and stay on to
let you know if there
is a problem.
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 147.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you
should always leave the system on. You can turn
the traction control system off if you ever need to.
To turn the system off,
press and release this
button located on
the console.Press the traction control system button again to
turn the system back on. The DIC will display
the appropriate message when you press
the button.
Adding non-Saturn accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 233for more information.
Limited-Slip Rear Axle
Your vehicle may have a limited-slip rear
differential which provides maximum power and
performance. It is designed to give you additional
traction on snow, mud, ice, sand or gravel. It
works like a standard axle most of the time, but
when one of the rear wheels has no traction
and the other does, this feature will allow
the wheel with traction to move the vehicle.
During a sudden shift, such as shifting from
FIRST (1) to SECOND (2) gear at low engine
speeds or suddenly applying the clutch, you may
feel or hear a clunking or rattling noise. This is
normal.

Electronic Stability Control
Your vehicle may be equipped with 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). In
some cases, it may take approximately two miles
of driving before the system initializes.
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 144andElectronic Stability
Control (ESC)/Traction Control System (TCS)
Indicator/Warning Light (2.0L Engine Only)
on page 136.This light is located
on the instrument
panel cluster.
It will ash 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 maintain
directional control of the vehicle. Adjust your
driving accordingly. SeeDIC Warnings and
Messages on page 147.

Competitive Driving Mode
The driver can select this optional handling mode
by pressing the ESC/TCS button on the console
two times within a ve second time period.
COMPETITIVE MODE will be displayed in the DIC.
SeeDIC Warnings and Messages on page 147for
more information. Competitive Driving Mode allows
the driver to have full control of the rear wheels
while the ESC system helps maintain directional
control of the vehicle by selective brake application.
When Competitive Mode is selected, the traction
control system will not be operating. Adjust your
driving accordingly. This mode should only be used
for driving in closed course or track driving venues.
When you press the ESC button again, or restart the
vehicle, the ESC and TCS will be turned back on.
Notice:When traction control is turned off,
or Competitive Driving Mode is active, it is
possible to lose traction. If you attempt to shift
with the rear wheels spinning with a loss of
traction, it is possible to cause damage to the
transmission. Do not attempt to shift when the
rear wheels do not have traction. Damage
caused by misuse of the vehicle is not covered.
See your warranty book for additional
information.
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.

Driving Through Deep Standing Water
Notice:If you drive too quickly through deep
puddles or standing water, water can come in
through your engine’s air intake and badly
damage your engine. Never drive through water
that is slightly lower than the underbody of your
vehicle. If you cannot avoid deep puddles or
standing water, drive through them very slowly.
Driving Through Flowing Water
{CAUTION:
Flowing or rushing water creates strong
forces. If you try to drive through owing
water, as you might at a low water
crossing, your vehicle can be carried away.
CAUTION: (Continued)
CAUTION: (Continued)
As little as six inches of owing water
can carry away a smaller vehicle. If this
happens, you and other vehicle occupants
could drown. Do not ignore police warning
signs, and otherwise be very cautious
about trying to drive through owing water.
Some Other Rainy Weather Tips
Besides slowing down, allow some extra
following distance. And be especially careful
when you pass another vehicle. Allow yourself
more clear room ahead, and be prepared to
have your view restricted by road spray.
Have good tires with proper tread depth.
SeeTires on page 284.

Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted. Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any
distance at higher speeds, you may tend to think
you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such
as after a day’s work — do not plan to make
too many miles that rst part of the journey.
Wear comfortable clothing and shoes you can
easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out.Of course, you will nd experienced and able
service experts at Saturn retailers all across the
United States and Canada. They will be ready
and willing to help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full?
Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated
to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you delay
your trip a short time to avoid a major storm
system?
Maps:Do you have up-to-date maps?

Highway Hypnosis
Is there actually such a condition as highway
hypnosis? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch of road
with the same scenery, along with the hum of the
tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make
you sleepy. Do not let it happen to you! If it does,
your vehicle can leave the road in less than a
second, and you could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with
a comfortably cool interior.
Keep your eyes moving. Scan the road ahead
and to the sides. Check your rearview mirrors
and your instruments frequently.
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get
some exercise, or both. For safety, treat
drowsiness on the highway as an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different
from driving in at or rolling terrain.
216
ProCarManuals.com

If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that
can make your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all
uid levels and also the brakes, tires, cooling
system, and transmission. These parts can
work hard on mountain roads.
{CAUTION:
If you do not shift down, your brakes
could get so hot that they would not work
well. You would then have poor braking or
even none going down a hill. You could
crash. Shift down to let your engine assist
your brakes on a steep downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with
the ignition off is dangerous. Your brakes
will have to do all the work of slowing
down. They could get so hot that they
would not work well. You would then have
poor braking or even none going down a
hill. You could crash. Always have your
engine running and your vehicle in gear
when you go downhill.
Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when
you go down a steep or long hill.
Know how to go uphill. You may want to shift
down to a lower gear. The lower gears help
cool your engine and transmission, and you
can climb the hill better.

If You Are Caught in a Blizzard
If you are stopped by heavy snow, you could
be in a serious situation. You should probably
stay with your vehicle unless you know for
sure that you are near help and you can hike
through the snow. Here are some things to do
to summon help and keep yourself and your
passengers safe:
Turn on your hazard ashers.
Tie a red cloth to your vehicle to alert police
that you have been stopped by the snow.
Put on extra clothing or wrap a blanket
around you. If you do not have blankets
or extra clothing, make body insulators
from newspapers, burlap bags, rags, oor
mats — anything you can wrap around
yourself or tuck under your clothing to
keep warm.You can run the engine to keep warm, but be
careful.

ProCarManuals.com

{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see
it or smell it, so you might not know it is in
your vehicle. Clear away snow from around
the base of your vehicle, especially any
that is blocking your exhaust pipe. And
check around again from time to time to be
sure snow does not collect there.
Open a window just a little on the side of
the vehicle that is away from the wind.
This will help keep CO out.Run your engine only as long as you must. This
saves fuel. When you run the engine, make it go
a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat
that you get and it keeps the battery charged.
You will need a well-charged battery to restart the
vehicle, and possibly for signaling later on with
your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window
almost all the way to preserve the heat. Start
the engine again and repeat this only when you
feel really uncomfortable from the cold. But do it as
little as possible. Preserve the fuel as long as
you can. To help keep warm, you can get out of
the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
