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, do the following:
1. Find your current location and variance zone number
on the map.

Convex Outside Mirror
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 or left lane,
you could hit a vehicle. Check your inside
mirror or glance over your shoulder before
changing lanes.
Heated Outside Rearview Mirrors
When you operate the rear window defogger, a defogger
also warms the heated driver's and passenger's outside
rearview mirrors to help clear them of ice, snow and
condensation. See ªRear Window Defoggerº in the
Index for more information.
Electrochromic Rearview Outside Mirror
with Curb View Assist (If Equipped)
If your vehicle has this feature, the driver's outside
mirror will adjust for the glare of the headlamps behind
you. See ªElectrochromic Day/Night Rearview Mirror
with Compass and OnStar

º earlier in this section.
If your vehicle is equipped with memory mirrors, it will
also be capable of performing the curb view assist
mirror function. This feature will cause the passenger's
and/or driver's mirror to tilt to a preselected position
when the vehicle is in REVERSE (R). This feature may
be useful in allowing you to view the curb when you are
parallel parking.
When the vehicle is shifted out of REVERSE (R) and a
short delay has occurred, the passenger's and/or driver's
mirror will return to its original position.
To change the preselected tilt position, adjust the mirrors
to the desired position while the vehicle is in
REVERSE (R). When the vehicle is shifted out of
REVERSE (R), this new position is saved in memory as
the tilt position.
This feature can be enabled/disabled through the Driver
Information Center. See ªPersonalization Featuresº in
the Index for more information.
