To adjust the HUD so you can see it properly:
1. Start your engine and turn the dimmer switch knob
to the desired HUD image brightness.
The brightness of the HUD image is determined by
the ambient light conditions in the direction your
vehicle is facing and where you have the HUD
dimmer control set. If you are facing a dark object or
a heavily shaded area, your HUD may anticipate that
you are entering a dark area and may begin to dim.
2. Adjust the driver's seat. If you change your seat
position later, you may have to readjust your HUD.
3. Press the UP or DN buttons until the HUD image is
easy to see and then press the DN switch until the
HUD image is as low as possible, but, remains in
full view straight ahead near the front bumper.
The HUD image can only be adjusted up and down,
- -
not side to side.
4. To turn the image off, turn the dimmer knob
counterclockwise to OFF.
If the sun comes out or it becomes cloudy, you may
need to adjust the HUD brightness again using the
dimmer control. Polarized sunglasses could make the
HUD image harder to see.
2-116
To change from English to metric units, push the
MODE button located to the right of the steering wheel.
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.
If the ignition is on and you can't see the HUD image,
check to see if one of the following has occurred:
D
Something is covering the HUD unit.
D
The HUD dimmer control is adjusted properly.
D
The HUD image is adjusted to the proper height.
D
Ambient light (in the direction your vehicle is facing)
is low.
D
A fuse is blown. See "Fuses and Circuit Breakers"
in the Index.
Keep in mind that your windshield is part of the
HUD system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD or
your HUD image may look blurred and out of focus.
