Memory Position Recall
NOTE:
• For vehicles equipped with an automatictransmission, the vehicle speed must be
lower than 5 mph to recall memory posi-
tions. If a recall is attempted when the
vehicle speed is greater than 5 mph, a
message will be displayed in the instru-
ment cluster display.
•
For vehicles equipped with a manual trans-
mission, the vehicle speed must be at 0 mph
(0 km/h) to recall memory positions. If a
recall is attempted with the vehicle speed
above 0 mph (0 km/h), a message will appear
in the instrument cluster display.
Driver One Memory Position Recall
• To recall the memory settings for driver one using the memory switch, push memory
button (1) on the memory switch.
• To recall the memory settings for driver one using the key fob, push the unlock button
on the key fob linked to memory position 1. Driver Two Memory Position Recall
• To recall the memory setting for driver two
using the memory switch, push memory
button (2) on the memory switch.
• To recall the memory settings for driver two using the key fob, push the unlock button
on the key fob linked to memory position 2.
A recall can be cancelled by pushing any of
the memory buttons during a recall (S, 1, or
2). When a recall is cancelled, the driver's
seat and the power pedals (if equipped) stop
moving. A delay of one second will occur
before another recall can be selected.
Easy Entry/Exit Seat
This feature provides automatic driver’s seat
positioning to enhance driver mobility when
entering and exiting the vehicle.
The distance the driver’s seat moves depends
on where you have the driver’s seat positioned
when you remove the key fob from the igni-
tion (or change the ignition to OFF, for ve-
hicles equipped with Keyless Enter-N-Go). • When you remove the key fob from the
ignition (or change the ignition to OFF, for
vehicles equipped with Keyless Enter-N-
Go), the driver’s seat will move about
2.4 inches (60 mm) rearward if the driver’s
seat position is greater than or equal to
2.7 inches (67.7 mm) forward of the rear
stop. The seat will return to its previously
set position when you place the ignition
into the ACC or RUN position.
• When you remove the key fob from the ignition (or change the ignition to OFF, for
vehicles equipped with Keyless Enter-N-
Go), the driver’s seat will move to a position
0.3 inches (7.7 mm) forward of the rear
stop if the driver’s seat position is between
0.9 inches and 2.7 inches (22.7 mm and
67.7 mm) forward of the rear stop. The seat
will return to its previously set position
when you place the ignition to the ACC or
RUN position.
• The Easy Entry/Easy Exit feature is disabled when the driver’s seat position is less than
0.9 inches (22.7 mm) forward of the rear
stop. At this position, there is no benefit to
the driver by moving the seat for Easy Exit
or Easy Entry.
