Mirrors
Automatic Dimming Rearview Mirror
The vehicle has an automatic dimming inside rearview
mirror with a compass display. Automatic dimming
reduces the glare of lights from behind the vehicle.
The dimming feature comes on and the indicator light
illuminates each time the vehicle is started.
O (On/Off): Press and hold O for about three
seconds to turn the dimming feature and compass
display on or off.
AUTO 3 (Vehicles with Intellibeam™): Press and
hold for approximately three seconds to turn the
compass display on or off. See Exterior Lamps on
page 4-25 for more information.
Cleaning the Mirror
Do not spray glass cleaner directly on the mirror. Use a
soft towel dampened with water.
Compass
Compass Operation
Press O or AUTO 3 , depending on the vehicle, to
turn the compass on or off.
When the ignition and the compass feature are on, after
a few seconds, the mirror will display the compass
heading. The compass automatically calibrates as the
vehicle is driven.
Compass Calibration
If after a few seconds, the display does not show the
correct direction, (for example, N for North), there
may be a strong magnetic field interfering with the
compass. Interference can be caused by a magnetic
antenna mount, magnetic note pad holder or a
similar magnetic item.
The compass can be placed in calibration mode
manually by pressing and holding
O or AUTO 3 ,
depending on the vehicle, until a C is shown in
the compass display.
The compass can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display
reads a direction.
