2008 SATURN SKY check engine

If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse, seeFuses
and Circuit Breakers on page 5-94. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the rst key may be
faulty. See your dealer/retailer who can service the
PASS-Key
®III+ to have a new key made. In an
emergency, contact Roadside Assistance. SeeRoadside
Assistance Program on page 7-7, for more information.
It may be possible for the PASS-Key
®III+ decoder
to “learn” the transponder value of a new or replacement
key. Up to 10 keys may be programmed for the
vehicle. The following procedure is for programming
additional keys only. If all the currently programmed
keys are lost or do not operate, you must see your
dealer/retailer or a locksmith who can service
PASS-Key
®III+ to have keys made and programmed
to the system.
See your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.To program the new key:
1. Verify that the new key has a
1stamped on it.
2. Insert the already programmed key in the ignition
and start the engine. If the engine will not start,
see your dealer/retailer for service.
3. After the engine has started, turn the key to
LOCK/OFF, and remove the key.
4. Insert the key to be programmed and turn it to the
ON/RUN position within ve seconds of the original
key being turned to the LOCK/OFF position.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the security light comes on
and stays on, you may be able to restart your engine if
you turn it off. Your PASS-Key
®III+ system, however,
is not working properly and must be serviced by your
dealer/retailer. Your vehicle is not protected by the
PASS-Key
®III+ system at this time.
If you lose or damage your PASS-Key
®III+ key, see
your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm. Do not race the engine
immediately after starting it. Operate the engine and
transmission gently to allow the oil to warm up
and lubricate all moving parts.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects components. If the ignition key
is turned to the START position, and then
released when the engine begins cranking, the
engine will continue cranking for a few seconds or
until the vehicle starts. If the engine does not
start and the key is held in START for many
seconds, cranking will be stopped after 15 seconds
to prevent cranking motor damage. To prevent
gear damage, this system also prevents cranking if
the engine is already running. Engine cranking
can be stopped by turning the ignition switch
to ACC/ACCESSORY or LOCK/OFF.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline.
Try pushing the accelerator pedal all the way to the
oor and holding it there as you hold the key in
START for up to a maximum of 15 seconds. Wait at
least 15 seconds between each try, to allow the
cranking motor to cool down. When the engine starts,
let go of the key and accelerator. If the vehicle starts
briey but then stops again, do the same thing.
This clears the extra gasoline from the engine.
Do not race the engine immediately after starting it.
Operate the engine and transmission gently until the
oil warms up and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, your
engine might not perform properly. Any resulting
damage would not be covered by your vehicle’s
warranty.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages on
your vehicle.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As the
details show on the next few pages, some warning lights
come on briey when you start the engine just to let you
know they are working. If you are familiar with this
section, you should not be alarmed when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
as you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s
advice. Waiting to do repairs can be costly and even
dangerous. So get to know your vehicle’s warning lights
and gages. They can be a big help.

Electronic Stability Control (ESC)/
Traction Control System (TCS)
Indicator/Warning Light
This light is located in the
center of the instrument
panel cluster.
For vehicles that have the Electronic Stability Control
(ESC) system or the Traction Control System (TCS),
this warning light should come on briey when the
engine is started.
If the warning light does not come on then, have it xed
so it will be ready to warn you if there is a problem.
This light, along with the appropriate Driver Information
Center (DIC) messages, indicates when the ESC
system and the TCS are working or are disabled.If this light is on and not ashing, the TCS and
potentially the ESC system have been disabled. Check
your DIC messaging to determine which feature(s) is
no longer functioning and whether it is because of
the driver turning off the feature(s), or the system may
not be working properly and your vehicle requires
service. If the TCS is disabled, wheel spin will not be
limited. If the ESC system is disabled, the system
will not aid in maintaining vehicle directional control.
In either case, adjust your driving accordingly.
If the light is on and ashing, the TCS or the ESC
system is actively working. Check the DIC messaging
for details to determine which system is working.
If the LOW TRACTION message appears, the system is
limiting wheel spin. If the ESC ACTIVE message
appears, the system is aiding in maintaining vehicle
directional control.
