the desired position.
2. Press and hold the 1 or 2 (driver 1 or 2) button of the
memory control for three seconds. When you hear a
chime ring two times, the memory position is stored.
To do the same thing for a second driver, follow the
preceding steps, but press the other number of the
memory control. The memory feature only works when

Curb View Assist Mirrors
Your vehicle is equipped with the curb view assist
mirror feature. For this function to work, it must be
enabled in the SIC. See ªSICº in the Index for more
information.
When the vehicle is shifted into REVERSE (R) there
will be a three second delay before the curb view assist
mirror(s) tilt to a preselected position. 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
five
-second delay has passed, the selected mirrors will
return to the original position.
If further adjustment is needed after the mirror is tilted,
the mirror controls may be used.Adjusting the Tilt Angle of the Mirrors
Adjust the tilt angle for each outside mirror by doing
the following:
1. Enable the feature in the SIC (if it is not already).
See ªSICº in the Index for information on enabling
the tilt mirrors.
2. Place the vehicle in REVERSE (R) and allow the
mirrors to tilt.
3. Change the angle of the mirror tilt to the desired
angle with the mirror controls.
The mirrors are now set to the desired position. The next
time the vehicle is placed in REVERSE (R) and the
mirror tilt feature is enabled in the SIC, the mirrors will
move to the set position.
