5-34 Instruments and Controls
To adjust the HUD so it can be seen
properly, do the following:
1. Start the engine and press the
HUD dimmer control all the way
up by pressing the (+) button.
The brightness of the HUD
image is determined by the light
conditions in the direction the
vehicle is facing and where you
have the HUD dimmer control
set. If you are facing a dark
object or a heavily shaded area,
the HUD may anticipate that you
are entering a dark area and
may begin to dim.
It is possible for sunlight to
enter the HUD making it difficult
to see the image. The display
will return to normal when the
sunlight is no longer entering
the HUD.
2. Adjust the seat to a comfortable
driving position. If your seat
position changes, the HUD may
need to be re-adjusted.
3. Press the up or down arrows
to center the HUD image in
your view.
The HUD image can only be
adjusted up and down, not side
to side.
4. Press the dimmer control
downward until the HUD image
is no brighter than necessary.
To turn HUD off, press and hold the
( ) button until the HUD display
turns off.
If the sun comes out or it becomes
cloudy, the HUD brightness may
need to be adjusted again using
the dimmer control. Polarized
sunglasses could make the HUD
image harder to see.
The HUD information can be
displayed in one of six languages
including English, Spanish, French,
German, Italian, or Japanese. The
speedometer can be displayed in
either English or metric units.
To change the language and unit
selections, see Entering the
Personal Options Menu under
Vehicle Personalization on
page 5 55.
Clean the inside of the windshield
as needed to remove any dirt or film
that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household
glass cleaner on a soft, clean cloth.
Wipe the HUD lens gently, then dry
it. Do not spray cleaner directly on
the lens because the cleaner could
leak into the unit.
