Head Restraints{
Warning
With head restraints that are not
installed and adjusted properly, there is a
greater chance that occupants will suffer
a neck/spinal injury in a crash. Do not
drive until the head restraints for all
occupants are installed and adjusted
properly.
Front Seats
The vehicle's front seats have adjustable
head restraints in the outboard seating
positions.
Adjust the head restraint so that the top of
the restraint is at the same height as the
top of the occupant's head. This position
reduces the chance of a neck injury in a
crash.
To raise or lower the head restraint, press
the button on the side of the head restraint
and pull up or push the head restraint down
and release the button.
Pull and push on the head restraint after the
button is released to make sure that it is
locked in place.
The front seat outboard head restraints are
not removable.
Rear Head Restraints
The vehicle’s rear seat has head restraints in
the outboard seating positions that cannot
be adjusted.
The head restraint can be folded forward to
allow for better visibility when the rear seat
is unoccupied. To fold the head restraint,
press the button on the side of the head
restraint.
When an occupant is in the seat, always
return the head restraint to the upright
position until it locks into place. Push and
pull on the head restraint to make sure that
it is locked.

Reclining Seatbacks
{Warning
Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the seat belts
cannot do their job.
The shoulder belt will not be against
your body. Instead, it will be in front of
you. In a crash, you could go into it,
receiving neck or other injuries.
The lap belt could go up over your
abdomen. The belt forces would be there,
not at your pelvic bones. This could cause
serious internal injuries.
For proper protection when the vehicle is
in motion, have the seatback upright.
Then sit well back in the seat and wear
the seat belt properly.
Do not have a seatback reclined if the
vehicle is moving.

If either seatback is not locked, it could
move forward in a sudden stop or crash.
That could cause injury to the person
sitting there. Always push and pull on

Memory Seats
Overview
If equipped, the memory seat feature allows
drivers to save their unique driving positions
and a shared exit position. See“Saving
Seating Positions” later in this section. The
saved positions can be recalled manually by
all drivers. See “Manually Recalling Seating

remote key 1 and 2 can also recall them
automatically. See “Auto Seat Entry Memory
Recall” or“Auto Seat Exit Memory Recall”
later in this section. To enable automatic
recalls, turn on Seat Entry Memory and/or

later in this section. The memory
recalls may be cancelled at any time during

Identifying Driver Number
The vehicle identifies the current driver by
their remote key number 1–8. The current
remote key number may be identified by
Driver Information Center (DIC) welcome
message, “You are driver x for memory
recalls.” This message is displayed the first
few times the vehicle is turned on when a
different remote key is used. For Seat Entry
Memory to work properly, save positions to
the 1 or 2 memory button matching the

recommended to only carry one remote key
when entering the vehicle. Perform the
following if the welcome message is not
displayed:
1. Move all remote keys away from the vehicle.
2. Start the vehicle with another remote key. A DIC welcome message should
display indicating the driver number of
the other remote key. Turn the vehicle
off and remove the other remote key
from the vehicle. 3. Start the vehicle with the initial remote
key. The DIC welcome message should
display the driver number of the initial
remote key.
Saving Seating Positions

saving memory positions.
To save preferred driving positions to
1 and 2: 1. Turn the vehicle on or to ACC/ ACCESSORY. A DIC welcome message
may indicate the driver number of the
current remote key. See “Identifying

3. Press and release SET; a beep will sound.
4. Immediately upon releasing SET, press and hold memory button 1 or 2 matching
the current driver’s remote key number
until two beeps sound. If too much time
passes between releasing SET and
pressing 1 or 2, the two beeps will not
sound indicating memory position were
