Be sure to continue scanning the
displays, controls, and driving
environment just as you would in a
vehicle without HUD. If you never
look at the instrument panel cluster,
you may miss something important,
such as a warning light. Under
important warning conditions, the
CHECK GAGES warning will
illuminate in the HUD. View your
Driver Information Center (DIC) for
more information.
The HUD controls are located to the
left of the steering wheel.
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.
