check engine light PONTIAC VIBE 2008 Owners Manual

Immobilizer Operation
(Canada Only)
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
Your vehicle will have one of the following security lights,
located on the instrument panel to the left of the steering
wheel.
The security light will ash when the system is armed.When the key is inserted in the ignition the transponder in
the key head transmits an electronic code to the vehicle
and automatically cancels the system. Only the correct
key will start the vehicle.
If the engine does not start, there may be a problem
with your theft-deterrent system. Turn the ignition off
and try again.
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 5-91.
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 theft-deterrent system and have a new
key made.
If any of the following conditions occur, contact your
dealer/retailer.
The security light stays on.
The security light does not start ashing when the
key is removed from the ignition.
The security light ashes inconsistently.
See your dealer/retailer to have a new key with a
transponder made. Bring the key and key number
with you.
In an emergency, contact Roadside Assistance
Program. SeeRoadside Assistance Program on
page 7-6.

Warning Lights, Gages, and
Indicators
This section 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.

Charging System Light
This light will come on
briey when the ignition is
turned on, and the engine
is not running, as a check
to show you it is working.
It should go out when the engine is started. If it stays
on, or comes on while you are driving, you may have
a problem with the electrical charging system. Have
it checked by your dealer/retailer. Driving while this
light is on could drain your battery. If you must drive
a short distance with the light on, be certain to turn
off all your accessories, such as the radio and air
conditioner to help reduce the drain on the battery.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
If your vehicle has anti-lock brakes, this light should
come on when you turn the key to START. If it does not
come on then, have it xed so it will be ready to warn
you if there is a problem.

Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure that emissions are at acceptable levels for the life of
the vehicle, helping to produce a cleaner environment.
The check engine light comes on to indicate that there
is an OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. This can prevent more serious
damage to your vehicle. This system is also designed
to assist your service technician in correctly diagnosing
any malfunction.Notice:If you keep driving your vehicle with this
light on, after a while, the emission controls might
not work as well, your vehicle’s fuel economy might
not be as good, and the engine might not run as
smoothly. This could lead to costly repairs that
might not be covered by your warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of
your vehicle or replacement tires that do not match
your vehicle’s original tires can affect your vehicle’s
emission controls and can cause this light to come
on. Modications to these systems could lead to
costly repairs not covered by your warranty. This
could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 5-3.
This light comes on, as a check to show it is working,
when the ignition is turned to ON/RUN but the engine
is not running. If the light does not come on, have
it repaired. This light also comes on during a malfunction
in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and could damage the emission control system
on your vehicle. Diagnosis and service might
be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service might be required. United States
Canada
3-36

If the Light Is Flashing
The following can prevent more serious damage to your
vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see “If the Light Is
On Steady” following. If the light is still ashing, follow the
previous steps, and see your dealer/retailer for service as
soon as possible.
If the Light Is On Steady
You might be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install the
cap. SeeFilling the Tank on page 5-7. The diagnostic
system can determine if the fuel cap has been left off orimproperly installed. A loose or missing fuel cap allows
fuel to evaporate into the atmosphere. A few driving trips
with the cap properly installed should turn the light off.
Did you just drive through a deep puddle of water?
If so, your vehicle’s electrical system might be wet.
The condition is usually corrected when the electrical
system dries out. A few driving trips should turn the
light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. Poor fuel quality causes
the engine not to run as efficiently as designed. You
might notice this as stalling after start-up, stalling when
you put the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration — these
conditions might go away once the engine is warmed up.
This will be detected by the system and cause the light to
turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn
off, your dealer/retailer can check the vehicle. Your
dealer/retailer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced the battery or if the battery
has run down. The diagnostic system is designed to
evaluate critical emission control systems during normal
driving. This can take several days of routine driving.
If you have done this and your vehicle still does not pass
the inspection for lack of OBD system readiness, your
dealer/retailer can prepare the vehicle for inspection.
Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
This light will come on
briey when you start
your engine. If it does
not, have your vehicle
serviced.
When the light comes on and stays on, it means that oil is
not owing through your engine properly. You could be
low on oil and you might have some other system
problem.
3-38

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
alot 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 might have the Antilock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
If your vehicle has ABS, this warning light on the
instrument panel will come on briey when you start
your vehicle.
When you start the engine, or when you 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 or pulses a little. This is normal.
If there is a problem with ABS, the antilock brake
system warning light will stay on. SeeAntilock Brake
System Warning Light on page 3-33. United States
Canada

StabiliTrak®System
Your vehicle may have this feature. The StabiliTrak®
system helps provide integrated control of the systems
such as anti-lock brake system, traction control and
engine control. This system automatically controls the
brakes and engine to help prevent the vehicle from
skidding when cornering on a slippery road surface
or turning the steering wheel abruptly.
This system will activate when your vehicle speed
reaches or exceeds 9 mph (15 km/h), and will
deactivate when the vehicle speed reduces to
below 9 mph (15 km/h).
You may hear a sound in the engine compartment for a
few seconds when the engine is started or just after the
vehicle begins to move. This means that the system is in
the self-check mode, but does not indicate a malfunction.
If the vehicle is going to skid during driving, the traction
control system warning light will blink and an alarm
will sound intermittently. Adjust your driving accordingly.
This light warns that there
is a problem somewhere
in the traction control
system or StabiliTrak
®.
Panic Brake Assist
Your vehicle has a panic brake assist system that
monitors the intention of the driver while braking. If the
system senses that the driver has applied hard/fast
pressure to the brake pedal, the system will generate
additional pressure, making it easier for the driver to
maintain brake application. When this happens the brake
pedal will feel easier to push. Just hold the brake pedal
down rmly and let the system work for you. You may feel
the brakes vibrate, or you may notice some noise but this
is normal. The brakes will return to normal operation after
the brake pedal has been released.
The brake assist system becomes operational after
the vehicle has accelerated to a speed in excess
of approximately 6 mph (10 km/h). It stops operating
when the vehicle decelerates to a speed below
approximately 3 mph (5 km/h).

You can run the engine to keep warm, but be careful.
{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 the 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
the headlamps. Let the heater run for a while.

check the engine oil
level right away.
For more information, seeOil Pressure Light on
page 3-38. You should check the engine oil level
regularly; this is an added reminder.
Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
