1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
whether the headlamps are on or off, and where you
have the HUD dimmer control set.
2. Adjust the seat to your driving position. Slide the
image height adjuster control all the way up, raising
the image as far as possible.
3. Now slide the image height adjuster control down so
the image is as low as possible but still in full view.
4. Slide the dimmer control downward until the HUD
image is no brighter than necessary.
2-98
The HUD controls
are located in the
overhead console.
To turn the HUD display off, slide the dimmer control
all the way down.
If the sun comes out, the sky becomes cloudy, or if you
turn your headlamps on, you may need to adjust the
HUD brightness using the dimmer control. Polarized
sunglasses could make the HUD image harder to see.
To change the display from English to metric units,
push the ENG/MET button located to the left of the
steering column.
Care of the HUD
Clean the inside of the windshield as necessary to
remove any dirt or film that reduces the sharpness or
clarity of the HUD image.
To clean the HUD lens, spray household glass cleaner
on a soft, clean cloth. Gently wipe and dry the HUD
lens. Do not spray cleaner directly on the lens to avoid
cleaner leaking inside the unit.
