Keys, doors and windows29Exterior mirrors
Convex shape
The convex exterior mirror contains
an aspherical area and reduces blind spots. The shape of the mirror makes objects appear smaller, which will
affect the ability to estimate
distances.
Electric adjustment

turning the control to left (L) or right
(R) . Then swivel the control to adjust
the mirror.
In position 0 no mirror is selected.
Folding mirrors
For pedestrian safety, the exterior
mirrors will swing out of their normal
mounting position if they are struck
with sufficient force. Reposition the mirror by applying slight pressure tothe mirror housing.
Electric folding
Turn control to 0, then push the
control down. Both exterior mirrors
will fold.
Push the control down again - both
exterior mirrors return to their original position.
If an electrically folded mirror is
manually extended, pressing down
the control will only electrically extend
the other mirror.
