Exterior Rear View Mirrors
Turn key in steering lock to position 2
(with either front door open, the
mirrors can be operated with key
removed or in steering lock
position 0 or 1).
Turn switch to select the mirror to be
adjusted.
To adjust, move the switch forward,
backward or to either side.
Note:
The exterior mirrors have electrically
heated glass. The heater switches on
automatically, depending on outside
temperature.
If an exterior mirror housing is forcibly
pivoted from its normal position, it
must be repositioned by applying firm
pressure until it snaps into place.
Warning!
Exercise care when using the
passenger-side mirror. The
passenger-side exterior mirror is
convex (outwardly curved surface
for a wider field of view). Objects in
mirror are closer than they appear.
Check your inside rear view mirror
or glance over your shoulder before
changing lanes.
