Trailer-Tow Mirrors

If equipped, adjust trailer-tow
mirrors for a clear view of the area
behind you. Manually pull out the
mirror head to extend it for better
visibility when towing a trailer.
The lower portion of the mirror is
convex. A convex mirror's surface is
curved to see more from the driver
seat. The convex mirror can be
adjusted manually to the driver
preferred position for better vision.
The mirror may have a turn signal
arrow that flashes in the direction of
the turn or lane change.
If equipped, the mirror housing may
have auxiliary cargo and clearance
lamps. See Cargo Lamp on
page 6-6 and Exterior Lamp
Controls on page 6-1.

Power Mirrors

Using hood-mounted air deflectors
and add-on convex mirror
attachments could decrease mirror
performance.
