SET/memory switches
The memory seat 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 be canceled
through “Vehicle settings” in the vehicle
information display by performing the fol-
lowing:
.
Switch the “Exit Seat Slide” ON to OFF.
For additional information, refer to “Ve-
hicle settings” (P.2-23).
. Switch the “Exit Steering Up” ON to OFF.
For additional information, refer to “Ve-
hicle settings” (P.2-23).

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 memory switch. 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).
3. Push the SET switch and, within 5 seconds, push the memory switch (1 or
2) fully for at least 1 second.
The indicator light for the pushed mem-
ory switch will stay on for approximately 5 seconds after pushing the switch.
When the memory is stored in the
memory switch (1 or 2), a buzzer will
sound.
If memory is stored in the same memory
switch, the previous memory will be
deleted.
Linking Intelligent Key to a stored
memory position
The Intelligent Key can be linked to a stored
memory position with the following proce-
dure.
1. Follow the steps for storing a memory
position.
2. While the indicator light for the memory switch being set is illuminated for 5
seconds, push the

and then push the
button on the
Intelligent Key. The driver’s seat, steering
wheel and outside mirrors will move to the
memorized position.
Confirming memory storage
. Push the ignition switch to the ON
position and push the SET switch. If the
main memory has not been stored, the
indicator light will come on for approxi-
mately 0.5 second. When the memory
has stored in position, the indicator light
will stay on for approximately 5 seconds.
. If the battery cable is disconnected, or if
the fuse opens, the memory will be
canceled. In this case, reset the desired
position using the previous procedure.
. If optional Intelligent Keys are added to
your vehicle, the memory storage proce-
dure to switch 1 or 2 and linking
Intelligent Key procedure to a stored
memory position should be performed
again for each Intelligent Key. For addi-
tional Intelligent Key information, see
“Keys” (P.3-2).
