check engine CHEVROLET UPLANDER 2007 1.G Owners Manual

At times you may notice a decrease in range. This
is normal for any remote keyless entry system.
If the transmitter does not work or if you have to
stand closer to your vehicle for the transmitter
to work, try this:
Check the distance. You may be too far from
your vehicle. You may need to stand closer
during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement”
underRemote Keyless Entry System
Operation on page 121.
If you are still having trouble, see your dealer
or a qualied technician for service.
Remote Keyless Entry System
Operation
You can lock and unlock the vehicle’s doors and
the liftgate using the remote keyless entry
transmitter supplied with your vehicle.The remote keyless
entry transmitter shown
here is for a vehicle
equipped with the
remote vehicle start
feature and dual power
sliding doors.
The remote keyless entry transmitter supplied with
your vehicle will only contain the buttons specic
to your vehicle’s factory installed remote
system features.
/(Remote Vehicle Start):If your vehicle has
this feature, you can start the engine from outside
the vehicle. See “Remote Vehicle Start” at the
end of this section for more detailed information.

2. Gently pry the battery out of the transmitter.
Do not use the metal anges to pop out the
battery.
3. Replace the battery.
4. Reassemble the transmitter. Make sure the
halves are snapped together tightly so water
will not get in.
5. Press and hold the lock and unlock buttons
for seven seconds to synchronize the
transmitter.
6. Check the transmitter operation.
Remote Vehicle Start
This feature allows you to start the engine from
outside the vehicle. It may also turn the rear
window defogger if the outside temperature is
below 45°F (7°C).
Laws in some local communities may restrict the
use of remote starters. For example, some
laws may require a person using remote start to
have the vehicle in view when doing so. Check
local regulations for any requirements on remote
starting of vehicles.
/(Remote Vehicle Start):If your vehicle has
the remote vehicle start feature, the remote
keyless entry transmitter will have a button with
this symbol on it.
An increased range of operation is provided with
the remote keyless entry transmitter that has
the remote vehicle start button.
If your vehicle is low on fuel, do not use the
remote start feature. The vehicle may run out of
fuel. The vehicle may also run out of fuel if
the vehicle is running for a long period of time
when parked on an incline facing downward with a
low fuel condition.

When the PASS-Key®III system senses that
someone is using the wrong key, it shuts down the
vehicle’s starter and fuel systems. The starter will
not work and fuel will stop being delivered to the
engine. Anyone using a trial-and-error method to
start the vehicle will be discouraged because of the
high number of electrical key codes.
If the engine does not start and the security
message comes on, the key may have a damaged
transponder. 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
instrument panel PASS KEY fuse. 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 or
a locksmith who can service the PASS-Key
®III to
have a new key made. SeeFuses and Circuit
Breakers on page 527.
It is 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. This procedure is for
learning additional keys only. If all the currently
programmed keys are lost or do not operate, youmust see your dealer or a locksmith who can
service PASS-Key
®III to have keys made
and programmed to the system.
See your dealer 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, do the following:
1. Verify the new key has PK3 stamped on it.
2. Insert the original, already programmed
key into the ignition lock cylinder and start the
engine. If the engine will not start, see your
dealer for service.
3. After the engine has started, turn the key to
LOCK and remove the key.
4. Insert the key to be programmed and turn it to
RUN within 10 seconds of removing the
previous key.
5. The security message will turn off once the
key has been programmed. It may not be
apparent that the security message went on
due to how quickly the key is programmed.
6. Repeat Steps 1 through 4 if additional keys
are to be programmed.

Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects the electrical
system. If the ignition key is turned to the
START position, and then released when the
engine begins cranking, the engine will
continue cranking until the vehicle starts or
until it exceeds the maximum cranking
time allowed, approximately 15 seconds to
prevent cranking motor damage. To prevent
starter-motor gear damage, this system
also prevents cranking if the engine is already
running. The engine cranking can be
stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
Notice:Holding your key in START for longer
than 15 seconds at a time will cause your
battery to be drained much sooner. And the
excessive heat can damage your starter motor.
Wait about 15 seconds between each try to
help avoid draining your battery or damaging
your starter.2. If the engine does not start in 10 seconds,
push the accelerator pedal about one-quarter
of the way down while you turn the key to
START. Do this until the engine starts.
As soon as it does, let go of the key.
3. If your engine still will not start, or starts but
then stops, it could be ooded with too much
gasoline. Try pushing your accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for
a maximum of 15 seconds. This clears the
extra gasoline from the engine. If the engine
still will not start, or starts briey but then
stops again, repeat Step 1 or 2, depending on
the temperature. When the engine starts,
release the key and the accelerator pedal.
Notice:Your 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. 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
that may be on your vehicle. The pictures will
help you locate them.
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 your 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
you will see in the details on the next few
pages, some warning lights come on briey when
you start the engine just to let you know they’re
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’s a problem with your
vehicle.
When one of the warning lights comes on and
stays on when 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 please get to know your warning lights and
gages. They’re a big help.

If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s airbag or airbags. See
Passenger Sensing System on page 106for more
on this, including important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of an airbag. SeeAirbag
Readiness Light on page 234.
Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, but the
engine is not running,
as a check to show you
it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with a
generator drive belt, or another electrical problem.
Have it checked right away. 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.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure 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 a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may 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 awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by your
warranty.
Notice:Modications made to the engine,
transaxle, 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 may
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 426.

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.
If the Light is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding 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 for service as
soon as possible.
243

If the Light Is On Steady
You may 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 433.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed. A
loose or missing fuel cap will allow 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 electrical system may be wet. The
condition will usually be 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 429. Poor fuel
quality will cause your engine not to run as
efficiently as designed. You may 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 may 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 can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.
244

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or may 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 your
battery or if your battery has run down. The
diagnostic system is designed to evaluate critical
emission control systems during normal driving.
This may 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 GM dealer can prepare the vehicle
for inspection.
