wheel is in the uppermost tilt position,
the steering wheel will no longer be
able to move upward when the
easy-entry/exit feature is activated.
If the current seat position falls into a
factory-set position range and the sys-
tem recognizes the current seat posi-
tion to be rearward enough for easy
entry and exit, the driver’s seat will not
move to the rear when the
easy-entry/exit feature is activated.
iFor safety reasons, the driver’s seat will
not return to its last set position with
the easy-entry/exit feature activated if
the system recognizes the last set posi-
tion as an extreme forward position. In-
stead, the driver’s seat will remain at or
move to a factory-set maximum for-
ward position. To again fully return the
driver’s seat to your last set position or
to memory position, adjust the seat to
the desired position or press and hold

Warning
G
Make sure all seats are properly locked in
position before driving off. Do not drive with
seats not properly locked.
Never ride in a moving vehicle with the seat
not properly locked as this can be danger-
ous. The seat could move forward and the
seat backrest could fold. You could slide un-
der the seat belt during braking, vehicle ma-
neuvers, or in an accident. If you slide under
it, the belt would apply force at the abdomen
or neck. That could cause serious or even fa-
tal injuries.
The seat backrest and seat belt provide the
best restraint when the wearer is in a nearly
upright position and the belt is properly po-
sitioned on the body.

Warning!
G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats. Re-
gardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriate infant or
toddler restraint, or booster seat recom-
mended for the size and weight of the child.
For additional information, see “Children in
the vehicle” (
page 82).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a nearly upright position and
belts are properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 50).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.

tial for injury to the head and neck in the
event of an accident or similar situation.
