ECO PONTIAC GRAND PRIX 2007 Owner's Guide

To turn off the automatic headlamp feature when it
is dark outside, move the exterior lamp control
to the parking lamp position. The parking lamps
will remain illuminated and the headlamps will turn
off. The fog lamps will also go on if they were
on previously.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Fog Lamps
If equipped, fog lamps provide brighter roadway
lighting for better vision in foggy or misty
conditions.
-(Fog Lamps):Turn the second band on the
exterior lamps control lever to this position to
turn the fog lamps on. The band will return to its
original position.
This symbol appears on
the instrument panel
cluster when the
fog lamps are on.To turn the fog lamps off, turn the band up to the
fog lamp symbol and release it. The band will
return to its original position. If the high-beam
headlamps are on, the fog lamps will turn off. The
fog lamps will go on again when the low-beam
headlamps are turned back on.
The parking lamps must be on for the fog lamps
to work.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left
on after the ignition has been turned to off, the
exterior lamps will turn off after about 10 minutes.
This protects the battery from being drained.
Use the exterior lamp control to turn the lamps
back on, if they are still needed.
Interior Lamps
The interior lamps can be controlled, or
automatically turn on or off under certain conditions.
They are explained in the following text.
146

Entry Lighting
The entry lighting feature turns the interior lights
on before anyone enters the vehicle. The
interior lamps will come on for 40 seconds when
the doors are unlocked using the remote
keyless entry transmitter and the ignition is in
OFF. After 40 seconds have elapsed, the interior
lamps will slowly fade out. The lamps will fade
out before 40 seconds have elapsed if one of the
following is done:
Lock all doors using the remote keyless entry
transmitter.
Lock the doors using the power door lock
switch.
When any door is opened, entry lighting is
cancelled. The interior lamps will stay on while
any door is opened and slowly fade out when all
doors are closed. The interior lamps may stay
on for up to 25 seconds after all doors have been
closed if they have not been locked.
Delayed Entry Lighting
The delayed lighting feature will continue to light
the interior of the vehicle for 25 seconds after
all the doors have been closed. Delayed lighting
will not occur while the ignition is in RUN or ACC.
After 25 seconds have elapsed, the interior
lamps will slowly fade out. The lamps will fade out
before the 25 seconds have elapsed if one of
the following is done:
The ignition is turned to RUN or ACC.
The doors are locked using the remote keyless
entry transmitter.
The doors are locked using the power door
lock switch.
To turn the delayed lighting feature off or on, see
“Personal Programming Modes” underDIC
Vehicle Customization on page 226DIC Controls
and Displays.
148

Delayed Exit Lighting
For exiting the vehicle at night, the vehicle is
equipped with the delayed exit lighting feature. After
the key is removed from the ignition, the interior
lamps will light for up the amount of seconds set in
the Driver Information Center (DIC). See “Personal
Programming Mode Screens” underDIC Vehicle
Customization on page 226. After the set time has
elapsed, the interior lamps will slowly fade. The
lamps will fade before the set time has elapsed if
one of the following is done:
The ignition is turned to RUN or ACC.
The doors are locked using the remote keyless
entry transmitter.
The doors are locked using the power door lock
switch.
When any door is opened, delayed exit lighting is
cancelled. The interior lamps will stay on while
any door is opened and will slowly fade out when
all the doors are closed. The interior lamps will
stay on for the set time after all the doors
have been closed if they have not been locked.
To turn the delayed exit lighting feature off or on,
see “Personal Programming Mode Screens”
underDIC Vehicle Customization on page 226.
Front Reading Lamps
If the vehicle has a sunroof, there are reading
lamps in front of the sunroof switch located on the
headliner. These lamps will come on when the
doors are opened. Press the side of each reading
lamp to turn them on and off when the doors
are closed.
Overhead Console Reading Lamps
The vehicle may have reading lamps on the
overhead console. These lamps will turn on when
the doors are opened. When the doors are
closed, press the side of each lamp to turn them
on and off.
Rear Assist Handle Reading Lamps
If the vehicle has a reading lamp on each rear
assist handle, press the side of each lamp to turn
it on or off.
149

Electric Power Management
The vehicle has Electric Power Management
(EPM) that estimates the battery’s temperature and
state of charge. It then adjusts the voltage for
best performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC), you
may see the voltage move up or down. This is
normal. If there is a problem, an alert will be
displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active. If this
message is displayed, it is recommended that the
driver reduce the electrical loads as much as
possible. SeeDIC Warnings and Messages on
page 200.

Fan
9
(Fan):Turn the knob by this symbol, located on
the left side of the climate control panel, clockwise
or counterclockwise to increase or decrease the fan
speed. The fan speed will be temporarily reduced
between the transition to a new mode. The fan will
resume the original speed when the transition to the
new mode is complete.
9(Off):Turn the knob to this position to turn the
climate control system off. Only the heated seat
and/or rear defrost can be operated when the fan
is off.
Mode
Turn the middle knob to select the following modes:
H(Vent) (Outside Air):This mode directs
outside air to the instrument panel outlets. If driving
in city traffic, and the vehicle is stopped and
idling, or the weather is hot, press the recirculation
button. To prevent the air inside the vehicle
from becoming stale, be sure to turn off
recirculation periodically.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets, and the remaining
air to the oor outlets. Some air may be directed
toward the windshield. Slightly cooler air is directed
to the instrument panel outlets and warmer air is
directed to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed toward
the side window outlets and a little air directed to
the windshield.
In this mode, the system will automatically use
outside air. The air conditioning compressor will
be engaged unless the outside temperature
is 40°F (4°C) or below.
Recirculation cannot be selected when in this
mode even though the indicator light comes on
when the recirculation button is pressed.
The middle knob on the climate control panel can
also be used to select the defog or defrost mode.
158

Air Conditioning
#
(Air Conditioner):Press this button to turn
the air conditioning compressor on or off. An
indicator light to the right of the button will come
on. This button has no control over the air
conditioning compressor when in Floor/Defog and
Defrost modes. The instrument panel brightness
control may have to be adjusted to the highest
setting in order to see the indicator. See
Instrument Panel Brightness on page 147for
additional information.
On hot days during the vehicle’s initial start-up,
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 quicker cool down on hot days, do the
following:
1. Select any mode setting between vent and
the setting before defrost.
2. Select the air conditioner.
3. Select the coolest temperature.
4. Select the highest climate control fan speed.Using these settings will set recirculation for quicker
cool down (the light indicator will not turn on).
If outside air is desired, press the recirculation
button twice.
Using these settings together for long periods of
time may cause the air inside the vehicle to
become too dry. To prevent this from happening,
after ve minutes the recirculation door will
open slightly to allow some outside air into the
vehicle.
The air conditioning system removes moisture
from the air, so sometimes there may be a small
amount of water dripping underneath the
vehicle while it is idling or after the engine is
turned off. This is normal.
Recirculation
h
(Recirculation):Press this button to
activate the recirculation mode. With this selection,
inside air is recirculated into the vehicle. This
mode reduces outside air and odors from entering
the vehicle. It may also help to heat or cool the
air inside the vehicle more quickly.
160

6(Floor):This mode directs most of the air to
the oor outlets with some air directed to the
side window outlets, and a little air directed to the
windshield.
#(Air Conditioning):Press this button to turn
the air conditioning compressor on or off. The
indicator light on the button will come on when the
air conditioning is on.
?(Recirculation):Press this button to turn
the recirculation mode on or off. This mode keeps
outside air from coming in the vehicle. It can be
used to help reduce the outside air and odors that
may enter the vehicle or help to cool the air
inside the vehicle quicker.
Recirculation is not available in defrost or
oor/defog mode. Pressing the recirculation button
will turn on the indicator light.
Using recirculation for long periods of time may
cause the air inside your vehicle to become
too dry. To prevent this from happening, after the
air in your vehicle has cooled, turn the
recirculation mode off.
z(Heated Seats):Press this button to turn the
heated seats on and off. The button on the left
controls the driver’s seat and the button on
the right controls the passenger’s seat. See
Heated Seats on page 10for additional
information.
Sensors
The solar sensor on your vehicle monitors the
solar radiation and the air inside of your vehicle,
then uses the information to maintain the selected
temperature by initiating needed adjustments to
the temperature, the fan speed and the air delivery
system. The system may also supply cooler air
to the side of the vehicle facing the sun. The
recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located
in the center of the instrument panel, near the
windshield, or the system will not work properly.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on the vehicle. The pictures help
to 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 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 the vehicle’s functions. As
the details show on the next few pages, some
warning lights come on briey when the engine is
started just to indicate 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 the vehicle’s functions. Often
gages and warning lights work together to
indicate when there is a problem with the vehicle.
When one of the warning lights comes on and
stays on while the vehicle is being driven, or when
one of the gages shows there may be a problem,
check the section that tells you what to do
about it. Follow this manual’s advice. Waiting to
do repairs can be costly – and even dangerous.
So please get to know the vehicle’s warning lights
and gages. They can be a big help.
The vehicle also has a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information
Center (DIC) on page 186for more information.

Instrument Panel Cluster
The instrument panel cluster is designed to show at a glance how the vehicle is running. It will show how
fast the vehicle is going, about how much fuel is in the fuel tank, and many other things needed to
drive the vehicle safely and economically.

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.
Safety Belt Reminder Light
When the key is turned to RUN or START, a
chime will sound for several seconds to remind
you and your passengers to buckle your
safety belts. The driver safety belt light will also
come on and stay on for several seconds, then it
will ash for several more. You should buckle
your seat belt.
If the driver’s belt is
buckled, neither the
chime nor the light will
come on.
