2008 PONTIAC GRAND PRIX Owners Manual

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 3-89. 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 ON/RUN or
ACC/ACCESSORY.
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” under
DIC Vehicle Customization on page 3-89.
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.

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 3-67.
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 LOCK/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 ON/RUN or
ACC/ACCESSORY.
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, transmission 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 has a navigation
radio. The images are projected by the HUD lens
located on the driver’s side of the instrument panel.
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” under
DIC Operation and Displays (Uplevel DIC with
Trip Computer) on page 3-55orDIC Operation and
Displays (Base Level DIC) on page 3-62.
The HUD information appears as an image focused
out toward the front of the vehicle.
3-23

When the ignition key is turned to ON/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

STABILITY CONTROL ACTIVE
The HUD will temporarily display the TRACTION
CONTROL OFF message when the traction control
system is turned off.
The HUD will temporarily display the CRUISE SET
message when cruise control is activated or cruise
speed is increased.
Notice:If you try to use the HUD image as a
parking aid, you may misjudge the distance and
damage your vehicle. Do not use the HUD image
as a parking aid.When the HUD is on, the speedometer reading will
continually be displayed. The current radio station or
CD track number will display for a short period of time
after the radio or CD track status changes. This will
happen whenever one of the radio controls is pressed.
The speedometer size will be reduced when radio,
CD information, warnings, or turn-by-turn guidance
information are displayed on the HUD.
The HUD control is
located on the console.
