Battery Run-Down Protection
This vehicle has a feature to help prevent the battery
from being drained, if the interior courtesy lamps,
reading/map lamps, visor vanity lamps or trunk lamp
are accidentally left on. If any of these lamps are
left on, they will automatically turn off after 10 minutes,
if the ignition is off. The lamps will not come back
on again until one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off,
then on again.
The headlamps will timeout after 10 minutes, if they
are manually turned on before the ignition is off.
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, RPM reading, transmission
position, outside air temperature, the tap shift gear,
and a brief display of the current radio station,
including XM information or CD track. It will also
display turn-by-turn navigation 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 will also appear on the HUD if
the vehicle has tap shift and it is active.
3-20

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). SeeDIC Vehicle
Customization (With DIC Buttons) on page 3-75.
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 is ready.
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
The HUD will temporarily display CHECK GAGES and
ICE POSSIBLE when there are messages on the
DIC trip computer.
The HUD will also display the following messages on
vehicles with these systems, when they are active:
TRACTION CONTROL ACTIVE
STABILITRAK ACTIVE
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 radio information is changed.
The speedometer size will be reduced when radio,
CD information, warnings, or turn-by-turn navigation
information are displayed on the HUD.
3-21

Format Two:This display includes the information
in Format One without the transmission information
and the outside air temperature.
Format Three:This display includes all the information
in Format One along with a circular tachometer, but
without outside air temperature.
All formats will show the turn-by-turn navigation
information and provide details about the next driving
maneuver to be made. When you near your destination,the HUD will display a distance bar that will ll in the
closer you get to your destination. All navigation
information is provided to the HUD by the navigation
radio, if the vehicle has one.
The HUD image displayed on the windshield will
automatically dim and brighten to compensate for
outside lighting.
The HUD image can temporarily light up depending
on the angle and position of the sunlight on the
HUD display. This is normal and will change when
the angle of the sunlight on the HUD display changes.
Polarized sunglasses could make the HUD image
harder to see.
Care of the HUD
Clean the inside of the windshield as needed to remove
any dirt or lm that could reduce the sharpness or
clarity of the HUD image.
To clean the HUD lens, use a soft, clean cloth that has
household glass cleaner sprayed on it. Wipe the HUD
lens gently, then dry it. Do not spray cleaner directly on
the lens because the cleaner could leak into the unit.
