2008 CHEVROLET EQUINOX engine

Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of
your vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) 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. SeeAccessories
and Modifications on page 5-3.
This light comes on, as a check to show it is working,
when the ignition is turned 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.
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 the vehicle.
Turn the ignition 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 5-8.
The diagnostic system can determine if the fuel cap
has been left off or improperly 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.
SeeGasoline 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 might 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.

are located on the center of the instrument panel.The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was
last displayed before the engine was turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected. The top of the DIC display shows the shift
lever position indicator. SeeAutomatic Transmission
Operation (3.4L V6 with 5-Speed) on page 2-24or
Automatic Transmission Operation (3.6L V6 with
6-Speed) on page 2-27for more information.
If your vehicle has these feature, the DIC also displays
the compass direction and the outside air temperature
when viewing the trip and fuel information. If there is a
problem with the system that controls the temperature
display, the numbers will be replaced with dashes. If this
occurs, have the vehicle serviced by your dealer/retailer.
If an abnormal temperature reading is displayed for an
extended period of time, consult your dealer/retailer.
Under certain circumstances, especially when the
engine is idling, a delay updating the temperature

AVG (Average) SPD (Speed)
Press the trip/fuel button until AVG (Average) SPD
(Speed) displays. This display shows the average speed
of the vehicle in miles per hour (mph) or kilometers
per hour (km/h). This average is calculated based on
the various vehicle speeds recorded since the last reset
of this value. To reset the value, press and hold the
set/reset button. The display will return to zero.
AVG (Average) ECON (Economy)
Press the trip/fuel button until AVG (Average)
ECON (Economy) displays. This display shows the
approximate average miles per gallon (mpg) or liters per
100 kilometers (L/100 km). This number is calculated
based on the number of mpg (L/100 km) recorded
since the last time this menu item was reset. To reset
this display, press and hold the set/reset button.
The display will return to zero.
RANGE
Press the trip/fuel button until RANGE displays. This
display shows the approximate number of remaining
miles (mi) or kilometers (km) the vehicle can be
driven without refueling.
The fuel range estimate is based on an average of
the vehicle’s fuel economy over recent driving history
and the amount of fuel remaining in the fuel tank.
This estimate will change if driving conditions change.
For example, if driving in traffic and making frequentstops, this display may read one number, but if the
vehicle is driven on a freeway, the number may change
even though the same amount of fuel is in the fuel
tank. This is because different driving conditions produce
different fuel economies. Generally, freeway driving
produces better fuel economy than city driving.
If your vehicle is low on fuel, the FUEL LEVEL LOW
message will be displayed. See “FUEL LEVEL
LOW” underDIC Warnings and Messages on page 3-49
for more information.
Blank Display
This display shows no information.
