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.
For vehicles with 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 navigationinformation 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.
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 3-64.The HUD information appears as an
image focused out toward the
front of the vehicle.
When the ignition key is turned to
ON/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 also appear on
the HUD:
Turn Signal Indicators
High-Beam Indicator SymbolHUD Display on the Vehicle
Windshield
Instrument Panel 3-17

The three formats are as follows:
Format One:This display gives the
speedometer reading (in English
or metric units), turn signal
indication, high beam indication,
transmission positions, and
the outside air temperature.
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.

Warning Lights,
Gages, and Indicators
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
prevent injury.
Warning lights come on when there
may be or is a problem with one
of the vehicle’s functions. Some
warning lights come on briey when
the engine is started to indicate
they are working.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 a problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains what
to do. Follow this manual’s advice.
Waiting to do repairs can be
costly and even dangerous.
