To calibrate the compass, do the following:
1. Make sure CAL is displayed. If CAL is not
displayed, press and hold the on/off button
until CAL is displayed.
2. While CAL is displayed drive the vehicle in
circles at 5 mph (8 km/h) or less until the
display reads a direction.
Compass Variance
Compass variance is the difference between
earth’s magnetic north and true geographic north.
If the mirror is not adjusted for compass
variance, the compass could give false readings.
The mirror is set in zone eight upon leaving
the factory. It will be necessary to adjust the
compass to compensate for compass variance if
the vehicle is driven outside zone eight. Under
certain circumstances, such as a long distance,
cross-country trip, it will be necessary to adjust
the compass variance.
To adjust for compass variance, do the following:
1. Find your current location and variance
zone number on the zone map that follows.2. Press and hold the compass button until a Z
and a zone number appear on the display.
3. Once the zone number appears on the
display, press the compass button quickly
until you reach the correct zone number.
If CAL appears in the compass window,
the compass may need calibration. See
“Compass Calibration” listed previously.

Outside Power Mirrors
The controls for the
outside power mirrors
are located on the
driver’s door armrest.
Press the left or right side of the selector switch
located beneath the control pad to choose the left
or right mirror. Keep the selector switch in the
center position when not adjusting either outside
mirror.
To adjust the mirror, press one of the four arrows
located on the control pad to move the mirror
in the direction you want it to go. Adjust each
outside mirror so that you can see a little of your
vehicle, and the area behind your vehicle.
Adjust each mirror so a little of the side of the
vehicle can be seen while sitting in a comfortable
driving position. These mirrors are designed to
break away when necessary.
Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like
other vehicles) look farther away than
they really are. If you cut too sharply into
the right lane, you could hit a vehicle on
your right. Check your inside mirror or
glance over your shoulder before
changing lanes.
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be
seen from the driver’s seat. It also makes things
appear farther away than they really are.
