64 Seats and Restraints Warning (Continued)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.
Memory Seats If equipped, memory seats allow two
drivers to store and recall their
unique seat positions for driving the
vehicle, and a shared exit position
for getting out of the vehicle. Other
feature positions may also be set,
such as power mirrors, power
steering wheel, and adjustable
pedals, if equipped. Memory
positions are linked to RKE
transmitter 1 or 2 for automatic
memory recalls.
Before storing, 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) on the driver door
until two beeps sound. To manually
recall these positions, press and
hold 1, 2, or
B until the saved
position is reached.
The vehicle identifies the current
driver ’ s RKE transmitter number
(1 – 8).
