2007 PONTIAC G5 engine

h(Recirculate):Press this button to prevent
outside air and odors from entering the vehicle or to
help heat or cool the air inside the vehicle more
quickly. An indicator light above the button will
come on in this mode. The air conditioning
compressor also comes on. This mode is not
available for oor, defog and defrost modes. When
the recirculation button is pressed, the recirculate
indicator light will ash ve times and outside air will
be delivered. Operation in this mode during periods
of high humidity and cool outside temperatures may
result in increased window fogging. If window
fogging is experienced, select the defrost mode.
Outside Air:This mode allows outside air to
circulate through the vehicle. This mode is
automatically active if recirculate is not selected.
There is no button for outside air.
#(Air Conditioning):If your vehicle has air
conditioning, press this button to turn the air
conditioning system on or off. When this button is
pressed, an indicator light above the button will
come on to let you know the air conditioning
is activated.On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for the vehicle to cool down. It
also helps the system to operate more efficiently.
For quick cool down on hot days:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select air conditioning.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of
time may cause the air inside of the vehicle to
become too dry. To prevent this from happening,
after the air in the vehicle has cooled, turn off the
recirculation by pressing the button again.
The air conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your vehicle
while idling or after turning off the engine. This is
normal.
The air conditioning compressor cannot be turned
on when the fan is off.

Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to
clear fog or frost from the windshield and side
windows. Use the defog mode to clear the windows
of fog or moisture and warm the passengers. Use
the defrost mode to remove fog or frost from the
windshield more quickly. For best results, clear all
snow and ice from the windshield before defrosting.
Turn the left knob to select the defog or
defrost mode.
-(Defog):This mode directs about half of the air
to the windshield and the side window outlets and
half to the oor outlets. When you select this mode
the system runs the air conditioning compressor.
To defog the windows faster, turn the temperature
control knob clockwise to the warmest setting.
0(Defrost):This mode directs most of the air to
the windshield, with some air directed to the side
window outlets and the oor outlets. When you
select this mode the system runs the air
conditioning compressor. To defrost the windows
faster, turn the temperature control knob clockwise
to the warmest setting.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger will only work when the
ignition is in RUN.
<(Rear):Press the button to turn the rear
window defogger on or off. Be sure to clear as
much snow from the rear window as possible. An
indicator light above the button will come on to let
you know that the rear window defogger is
activated.
The rear window defogger will turn off about
15 minutes after the button is pressed. If turned on
again, the defogger will only run for about seven
minutes before turning off. If the vehicle is moving
faster than 50 mph (80 kph), the rear defogger will
stay on. The defogger can also be turned off by
pressing the button again or by turning off the
engine.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the repairs
would not be covered by your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.

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 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 please get to know your warning lights
and gages. They are a big help.

Speedometer and Odometer
Your speedometer lets you see your speed
in both miles per hour (mph) and kilometers
per hour (km/h).
Your vehicle’s odometer works together with the
driver information center. You can set a Trip A and
Trip B odometer. See “Trip Information” under
DIC Operation and Displays on page 174.
The odometer mileage can be checked without the
vehicle running. Simply open the driver’s door
and the mileage will be displayed briey.
If your vehicle ever needs a new odometer
installed, the new one will be set to the correct
mileage total of the old odometer.
Tachometer
The tachometer
displays the engine
speed in revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your
vehicle could be damaged, and the damages
would not be covered by your warranty. Do not
operate the engine with the tachometer in
the shaded warning area.

Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, and the engine
is not running, as a
check to show you it is
working.
Then 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. 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.
Up-Shift Light
Your vehicle may have an up-shift light. When this
light comes on, you should shift to the next higher
gear if weather, road, and traffic conditions allow
you to.
This light is located in
your instrument panel
cluster to the left of
the tachometer.

Anti-Lock Brake System Warning
Light
Your vehicle may have
an Anti-Lock Brake
System (ABS)
warning light.
The ABS warning light will come on briey when
you turn the ignition key to LOCK. This is normal.
If the light does not come on then, have it xed
so it will be ready to warn you if there is a problem.
If the light stays on, turn the ignition off, if the light
comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the
engine again to reset the system. If the light still
stays on, or comes on again while you are driving,
your vehicle needs service. If the regular brake
system warning light is not on, you still have brakes,
but you do not have anti-lock brakes. If the regular
brake system warning light is also on, you do not
have anti-lock brakes and there is a problem with
your regular brakes. SeeBrake System Warning
Light on page 165.
Enhanced Traction System
Warning Light
If your vehicle is
equipped with the
Enhanced Traction
System (ETS), this
warning light should
come on briey as you
start the engine.
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.
If the warning light stays on, or comes on when you
are driving, there may be a problem with your
Enhanced Traction System and your vehicle may
need service. When this warning light is on, the
system will not limit wheel spin. Adjust your driving
accordingly.
166

The Enhanced Traction System warning light may
come on for the following reasons:
If you turn the system off by moving the shift
lever to LOW (L), the warning light will come on
and stay on. To turn the system back on, move
the shift lever back to a position other than
LOW (L). The warning light should go off.
SeeEnhanced Traction System (ETS) on
page 226for more information.
The warning light will come on when you set
your parking brake with the engine running, and
it will stay on if your parking brake does not
release fully. If the transaxle shift lever is in any
position other than LOW (L) and the warning
light stays on after your parking brake is fully
released, it means there is a problem with the
system.
If the traction control system is affected by an
engine-related problem, the system will turn off
and the warning light will come on.
If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the transaxle shift lever is in any position
other than LOW (L), your vehicle needs service.
Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light will come on
when the engine has
overheated.
If this happens you should pull over and turn off
the engine as soon as possible. SeeEngine
Overheating on page 290for more information.
Notice:Driving with the engine coolant
temperature warning light on could cause your
vehicle to overheat. SeeEngine Overheating on
page 290. Your vehicle could be damaged, and
it might not be covered by your warranty. Never
drive with the engine coolant temperature
warning light on.
This light will also come on when starting your
vehicle. If it doesn’t, have your vehicle serviced.

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 268.
