Automatic Dimming Mirror Operation
O
:Press this button to turn the automatic
dimming feature on or off. The indicator light to
the left of the button will turn on or off to indicate
when the feature is on. Once the mirror is
turned off, it will remain off until it is turned back
on, or until the vehicle is restarted.
Compass Operation
Press the compass/temperature button once
briey to turn the display on or off.
Compass Calibration
The compass may need calibration if one of the
following occurs:
If CAL is displayed while driving in the vehicle.
After approximately ve seconds, the display
does not show a compass heading, N for
North, for example, there may be a strong
magnetic eld interfering with the compass.
Such interference may be caused by a
magnetic antenna mount, magnetic note pad
holder, or a similar magnetic item.
The compass does not display the correct
heading and the compass zone variance
is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed,
push in the compass/temperature button for
approximately nine seconds or until CAL is
displayed.
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.
161

Compass Variance
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 outside zone eight. Under certain
circumstances, as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. Compass variance is the
difference between earth’s magnetic north and true
geographic north. If not adjusted to account for
compass variance, your compass could give false
readings.
To adjust for compass variance:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold the compass/temperature
button for six seconds until a zone number
appears in the display.
3. Press the compass/temperature button on the
bottom of the mirror until the new zone
number appears in the display. After you stop
pressing the button, the display will show a
compass direction within a few seconds.
162

Cleaning the Mirror

with glass cleaner. Do not spray glass cleaner
directly on the mirror as that may cause the liquid
cleaner to enter the mirror housing.
Outside Manual Mirrors
Adjust your outside mirrors so you can just see
the side of your vehicle and have a clear view of
objects behind you. The mirrors can be folded
in to enter narrow areas.
The use of hood-mounted air deectors and

better visibility when towing a trailer.
These mirrors can be manually folded forward or
rearward. On the lower portion of the mirror is
a convex mirror. A convex mirror’s surface
is curved so you can see more from the driver’s
seat. The position of the convex mirror must
be adjusted manually to the driver’s preferred
position.

If your vehicle is equipped with this feature,
the driver’s outside mirror will adjust for the glare
of headlamps behind you. This feature is
controlled by the on and off settings found on the
electrochromic inside mirror.
Outside Curb View Assist Mirrors

outside mirrors are able to perform the curb view

and/or driver’s mirror to tilt to a preselected position
when the vehicle is in REVERSE (R).
The passenger’s and/or driver’s mirror will return to
its original position when the vehicle is shifted out of

occurred, the vehicle speed is greater than 8 mph

glass. A convex mirror’s surface is curved so you
can see more from the driver’s seat.
{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.
