Section 2 Features and Controls
2-1
Outside Power Mirrors
The controls for the
outside power mirrors, are
located on the driver’s
door armrest.
Move the selector switch located below the four-way
control pad to the left or right to choose either the
driver’s side or passenger’s side mirror. To adjust a
mirror, use the arrows located on the four-way control
pad to move the mirror in the desired direction.
Adjust each outside mirror so that a little of the vehicle
and the area behind it can be seen while sitting in a
comfortable driving position. Keep the selector switch in
the center position when not adjusting either outside
mirror.
Outside Power Heated Mirrors
For information on the operation of the outside power
mirrors seeOutside Power Mirrors on page 2-40.
If the vehicle has heated mirrors, they will warm up to
melt ice and snow, and remove condensation when the
defroster is turned on. SeeDual Automatic Climate
Control System on page 3-24orClimate Control System
on page 3-20.
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 side mirror is convex. A convex mirror’s
surface is curved so more can be seen from the
driver seat. It also makes things, like other vehicles,
look farther away than they really are.
