Linking log-in function to a stored
memory position
The log-in function can be linked to a stored
memory position with the following
procedure.
1. Place the ignition switch in the ON posi-tion while carrying the Intelligent Key that
was registered to the vehicle with a log-in
function.
NOTE:Make sure the Intelligent Keys are far apart.
Otherwise, the vehicle may detect the
wrong Intelligent Key.
2. Adjust the position of the driver’s seat, steering column and outside mirrors. For
additional information, see “Seats”
(P. 1-2), “Steering wheel” (P. 3-31) and
“Outside mirrors” (P. 3-34).
3. Place the ignition switch in the OFF position.
The next time you log in (selecting the user on
the display) after placing the ignition switch in
the ON position while carrying the Intelligent
Key, the system will automatically adjust to
the memorized driving position. For additional information, refer to the sepa-
rate INFINITI InTouch™ Owner’s Manual and

ENTRY/EXIT FUNCTION
This system is designed so that the driver's
seat and steering column will automatically
move when you the vehicle is engaged in the

easily get in and out of the driver’s seat.
The driver’s seat will slide backward and the
steering column will move up when the igni-
tion is switched to OFF and the driver’s door
is opened.
The driver’s seat and steering wheel will re-
turn to the previous position when the igni-
tion is switched to ON.
The entry/exit function can be adjusted or
canceled through the “Comfort & Conve-
nience” options of the “Settings” menu in the
lower touch-screen display by performing the
following:
• Switch the Lift Steering upon Exit from ON
to OFF.
• Switch the Slide Driver Seat Back on Exit from ON to OFF.

fuse opens, the stored memory positions will
be lost and some of the functions will be
restricted:
1. Drive the vehicle over 25 mph (40 km/h).
OR
2. Open and close the driver's door more than two times with the ignition switch in
the OFF position.
The entry/exit function should now work
properly.
