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.

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.

2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 73°F (22°C)
temperature setting and allow about 20 minutes
for the system to regulate. Use the driver’s or
passenger’s temperature buttons to adjust the
temperature setting as necessary. If you choose
the temperature setting of 60°F (15°C), the system
remains at the maximum cooling setting. If you
choose the temperature setting of 90°F (32°C),
the system remains at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Do not cover the solar sensor located on the top of
the instrument panel near the windshield. This sensor
regulates air temperature based on sun load and also
turns on your vehicle’s headlamps. For more information
on the solar sensor, see “Sensors” later in this section.
