saved, such as power mirrors and
power steering wheel, if equipped. Memory positions are linked to RKE
transmitter 1 or 2 for automatic
memory recalls.
Before saving, adjust all available
memory feature positions. Turn the
ignition on and then press and
release SET; a beep will sound.
Then immediately press and hold 1,
2, or
B(Exit) until two beeps
sound. To manually recall these
positions, press and hold 1, 2, or
B
until the saved position is reached.
Follow the instructions under
“Saving Memory Positions.”
The vehicle identifies the current
driver ’s RKE transmitter number (1–
8). See Remote Keyless Entry
(RKE) System Operation 029. Only
RKE transmitters 1 and 2 can be
used for automatic memory recalls.
A Driver Information Center (DIC)

transmitter number may display for
the first few ignition cycles following
a transmitter change. For Auto
Memory Recall to work properly,

Rear Seats
Rear Seat Reminder
If equipped, the message REAR
SEAT REMINDER LOOK IN REAR
SEAT displays under certain
conditions indicating there may be
an item or passenger in the rear
seat. Check before exiting the
vehicle.
This feature will activate when a
second row door is opened while
the vehicle is on or up to 10 minutes
before the vehicle is turned on.
There will be an alert when the
vehicle is turned off. The alert does
not directly detect objects in the rear
seat; instead, under certain
conditions, it detects when a rear
door is opened and closed,
indicating that there may be
something in the rear seat.
The feature is active only once each
time the vehicle is turned on and off,
and will require reactivation by
opening and closing the second row
doors. There may be an alert even
when there is nothing in the rear
seat; for example, if a child enteredthe vehicle through the rear door
and left the vehicle without the
vehicle being shut off.
The feature can be turned on or off.
See
Vehicle Personalization 0138.
Folding Seatbacks

belts and return them to their
normal stowed position before
folding a rear seat.

center of the seatback. Lower the
armrest to access the two
cupholders and the storage area.

Seat Belts
This section describes how to use
seat belts properly, and some things
not to do.
{Warning
Do not let anyone ride where a
seat belt cannot be worn properly.
In a crash, if you or your
passenger(s) are not wearing
seat belts, injuries can be much
worse than if you are wearing
seat belts. You can be seriously
injured or killed by hitting things
inside the vehicle harder or by
being ejected from the vehicle. In
addition, anyone who is not
buckled up can strike other
passengers in the vehicle.
It is extremely dangerous to ride
in a cargo area, inside or outside
of a vehicle. In a collision,
passengers riding in these areas
are more likely to be seriously
injured or killed. Do not allow(Continued)
Warning (Continued)
passengers to ride in any area of
the vehicle that is not equipped
with seats and seat belts.
Always wear a seat belt, and
check that all passenger(s) are
restrained properly too.
This vehicle has indicators as a
reminder to buckle the seat belts.
See Seat Belt Reminders 0120.
