2007 PONTIAC GRAND PRIX Owners Manual

Headlamps on Reminder
A warning chime will sound if the vehicle’s ignition
is off and the driver’s door is opened when the
exterior lamp control is left on in either the
headlamp or parking lamp position.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Daytime running lamps are required to
function at all times on all vehicles rst sold
in Canada.
A light sensor on top of the instrument panel
makes the DRL work, so be sure it is not covered.
The DRL system will make the low-beam
headlamps come on at reduced brightness when
the following conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.While the DRL are on, only the vehicle’s low-beam
headlamps will be on at reduced brightness.
The turn signal, taillamps, sidemarker and other
lamps will not be on. The instrument panel cluster
will not be lit up either.
When it is dark enough outside, the DRL will turn
off and the vehicle’s headlamps and parking
lamps will turn on. The other lamps that come on
with the headlamps will also come on.
When it is bright enough outside, the headlamps
will go off and the DRL will come on.
To idle the vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking
lamp position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to
off and back to AUTO.
This feature is not available for vehicles rst sold
in Canada.
145

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.

instrument panel lights.
Courtesy Lamps
When a door is opened, the courtesy lamps will
automatically come on. These lamps will also
come on when the interior lamps control is fully
turned clockwise.
Dome Lamp
If the vehicle does not have an overhead console,
it will have a dome light located in the front of
the headliner.
The switch on this lamp has three positions. The
on position will turn on the lamp anytime. The
door position will turn on the lamp whenever
a door is opened. The off position will shut off the
lamp completely, even while a door is opened.
147

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:

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

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.

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.
150

Battery Run-Down Protection
The vehicle has a feature to help prevent the
battery from draining in case the interior, trunk, or
underhood lamps are accidentally left on. If
any of these lamps are left on while the ignition is
in OFF, they will automatically turn off after
10 minutes. The lamps will not come back on
again until any of the following are done:
The ignition is turned to RUN or ACC.
The interior lamps control is turned completely
to the right, then back slightly to the left.
Open, or close and reopen, a door that is
closed.
If the vehicle has less than 15 miles (25 km) on
the odometer, the battery saver will turn off
the lamps after only three minutes.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright or too high
in your eld of view, it may take you more
time to see things you need to see when it
is dark outside. Be sure to keep the HUD
image dim and placed low in your eld
of view.
If the vehicle has the Head-Up Display (HUD),
some information concerning the operation of the
vehicle is projected onto the windshield. This
includes the speedometer reading, transaxle
positions, compass direction, outside air
temperature, the tap shift gear and the upshift
symbol if active, and a brief display of the current
radio station, including XM information or CD
track. It will also display turn-by-turn guidance
information if the vehicle is has a navigation radio.
The images are projected by the HUD lens
located on the driver’s side of the instrument panel.
151

The tap shift gear and the upshift symbol will also
appear on the HUD if the vehicle has tap shift
and it is active.
The HUD information can be displayed in one of
three languages, English, French, or Spanish. The
speedometer reading and other numerical values
can be displayed in either English or metric units.
The language selection and the units of
measurement are changed through the trip
computer in the Driver Information Center (DIC).
See “Options” underDIC Controls and Displays
(Base Level DIC) on page 186orDIC Controls and
Displays (Uplevel DIC with Trip Computer) on
page 190.
The HUD information appears as an image
focused out toward the front of the vehicle.
When the ignition key is turned to RUN, the HUD
will display an introductory message for a short
time, until the HUD has warmed up.
The following indicator lights come on the
instrument panel when activated and will also
appear on the HUD:
Turn Signal Indicators
High-Beam Indicator Symbol
