SET/memory switches
The automatic drive positioner system has
three features:
. Entry/exit function
. Memory storage
. Setting memory function
ENTRY/EXIT FUNCTION
This system is designed so that the driver’s
seat and steering column will automatically
move when the automatic transmission shift
lever is in the P (Park) position. This allows
the driver to get into and out of the driver’s
seat more easily.
The driver’s seat will slide backward and the
steering wheel will move up when the
driver’s door is opened with the ignition
switch in the LOCK position.
The driver’s seat and steering wheel will
return to the previous positions when the
ignition switch is pushed to the ACC posi-
tion.
The driver’s seat will not return to the
previous positions if the seat or steering
adjusting switch is operated when the seat is
at the exit position.
Cancel or activate entry/exit func-
tion
The shift lever must be in the P (Park)
position with the ignition switch in the OFF
position.
The entry/exit function can be activated or
canceled by pressing and holding the SET
switch for more than 10 seconds.
The entry/exit function can also be acti-
vated or canceled if the “Lift Steering upon Exit” key or “Slide Driver Seat Back on Exit”
key is turned to ON or OFF in the [Settings]
menu on the lower display. (See INFINITI
InTouch
TMOwner’s Manual.)
Initialize entry/exit function
If the battery cable is disconnected, or if the
fuse opens, the entry/exit function will not
work though this function was set on before.
In such a case, after connecting the battery
or replacing with a new fuse, open and close
the driver’s door more than two times after
the ignition switch is turned from the ON
position to the LOCK position. The entry/
exit function will be activated.
MEMORY STORAGE
Two positions for the driver’s seat, steering
column and outside mirrors can be stored in
the automatic drive positioner memory.
Follow these procedures to use the memory
system.
1. Move the shift lever to the P (Park)
position.
2. Adjust the driver’s seat, steering column and outside mirrors to the desired posi-
tions by manually operating each adjust-
ing switch. For additional information,
see “Seats” (P.1-3) and “Tilt/telescopic
steering” (P.3-29) and “Outside mirrors”
(P.3-37).
