WARNING
.Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and
receive neck or other serious injuries.
You could also slide under the lap belt
and receive serious internal injuries.
. For the most effective protection
when the vehicle is in motion, the
seat should be upright. Always sit
well back and upright in the seat with both feet on the floor and adjust the
seat belt properly. See “Precautions
on seat belt usage” (P.1-12).
. Do not leave children unattended
inside the vehicle. They could un-
knowingly activate switches or con-
trols. Unattended children could
become involved in serious accidents.
. To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require the
assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve- hicle on a warm day can quickly
become high enough to cause a sig-
nificant risk of injury or death to
people and pets.
. The seatback should not be reclined
further than necessary for comfort.
Seat belts are most effective when
the passenger sits well back and
straight up in the seat. If the seat-
back is reclined, the risk of sliding
under the lap belt and being injured is
increased.
CAUTION
When adjusting the seat positions, be
sure not to contact any moving parts to
avoid possible injuries and/or damages.
SEATS

FRONT SEATS
Front power seat adjustment
Operating tips:
.The power seat motor has an auto-reset
overload protection circuit. If the motor
stops during operation, wait 30 seconds,
then reactivate the switch.
. Do not operate the power seat switch for
a long period of time when the engine is
off. This will discharge the battery.
See “Memory seat” (P.3-33) for the seat
position memory function.
SSS1051
Forward and backward:
Moving the switch
forward or backward
will slide the seat forward or backward to
the desired position.
Reclining:
Move the recline switch
backward until
the desired angle is obtained. To bring the
seatback forward again, move the switch
forward.
The reclining feature allows adjustment of
the seatback for occupants of different sizes
for added comfort and to help obtain proper
seat belt fit. (See “Precautions on seat belt
usage” (P.1-12).) Also, the seatback can be
reclined to allow occupants to rest when the vehicle is parked.

REAR SEATS
Folding (if so equipped)
WARNING
. Never allow anyone to ride in the
trunk or on the rear seat when it is in
the fold-down position. Use of these
areas by passengers without proper
restraints could result in serious in-
jury in an accident or sudden stop.
. Properly secure all cargo with ropes
or straps to help prevent it from
sliding or shifting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured cargo
could cause personal injury.
. When returning the seatbacks to the
upright position, be certain they are
completely secured in the latched
position. If they are not completely
secured, passengers may be injured in
an accident or sudden stop.
. Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
rear seatback and trunk lid securely

WARNING
Head restraint/headrest supplement the
other vehicle safety systems. They may
provide additional protection against
injury in certain rear end collisions.
Adjustable head restraint/headrest
must be adjusted properly, as specified
in this section. Check the adjustment
after someone else uses the seat. Do not
attach anything to the head restraint/
headrest stalk, except for genuine
INFINITI accessories specifically tested
for use with the vehicle’s head restraint/
headrest stalk. Do not remove the head
restraint/headrest. Do not use the seat
if the head restraint/headrest has been
removed. If the head restraint/headrest
was removed, reinstall and properly
adjust the head restraint/headrest be-
fore an occupant uses the seating posi-
tion. Failure to follow these instructions
can reduce the effectiveness of the head
restraint/headrest. This may increase
the risk of serious injury or death in a
collision.
