2009 CHEVROLET TRAVERSE check engine

Light On Steady:An emission
control system malfunction has been
detected on the vehicle. Diagnosis
and service might be required.
An emission system malfunction
might be corrected by checking the
following items:
Make sure the fuel cap is fully
installed. SeeFilling the Tank
on page 5-7. 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.
If the vehicle has been driven
through a deep puddle of water,
the 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.
Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.If one or more of these conditions
occurs, change the fuel brand
used. It will require at least one
full tank of the proper fuel to turn
the light off.
SeeGasoline Octane on
page 5-5.
If none of the above have made the
light turn off, your dealer/retailer can
check the vehicle. The 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 the vehicle.
Failure to pass this inspection
could prevent getting a vehicle
registration.
Here are some things to know to
help the vehicle pass an inspection:
The vehicle will not pass this
inspection if the check engine
light is on with the engine
running, or if the key is in
ON/RUN and the light is not on.
The vehicle will not pass this
inspection if the OBD II (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 forinspection. This can happen
if the battery has recently been
replaced 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 this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
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. The engine can
become so hot that it catches re.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.Notice:Lack of proper engine
oil maintenance can damage
the engine. The repairs would
not be covered by the vehicle
warranty. Always follow the
maintenance schedule in this
manual for changing engine oil.
The oil pressure light should come
on briey as the engine is started. If it
does not come on have the vehicle
serviced by your dealer/retailer.
If the light comes on and stays on, it
means that oil is not owing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.

BATTERY SAVER ACTIVE
This message displays when the
system detects that the battery
voltage is dropping below expected
levels. The battery saver system
starts reducing certain features of
the vehicle that you may be able to
notice. At the point that the features
are disabled, this message is
displayed. It means that the vehicle
is trying to save the charge in the
battery.
