WARNING
• Do not ride in a moving vehicle when the
seatback is reclined. This can be danger-
ous. 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 un-
der the lap belt and receive serious inter-
nal injuries. •
For the most effective protection when
the vehicle is in motion, the seat should
be upright. Always sit well back and up-
right in the seat with both feet on the
floor and adjust the seat properly. For
additional information, see “Precautions
on seat belt usage” (P. 1-11).
• After adjustment, gently rock in the seat
to make sure it is securely locked.
• Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or make the
vehicle move. Unattended children could
become involved in serious accidents. •
To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm day
can quickly become high enough to cause
a significant risk of injury or death to
people and pets.
• Do not adjust the driver’s seat while
driving so full attention may be given to
vehicle operation. The seat may move
suddenly and could cause loss of control
of the vehicle.
• The seatback should not be reclined any
more than needed for comfort. Seat
belts are most effective when the pas-
senger sits well back and straight up in
the seat. If the seatback is reclined, the
risk of sliding under the lap belt and be-
ing injured is increased.
CAUTION
When adjusting the seat positions, be sure
not to contact any moving parts to avoid
possible injuries and/or damage.

FRONT POWER SEAT
ADJUSTMENT
Operating tips
• The power seat motor has an auto-resetoverload 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.
For additional information, see “Memory
seat” (P. 3-36).
Forward and backward
Moving the switch as shown will slide the
seat forward or backward to the desired
position.
Reclining
Move the recline switch as shown until the
desired angle is obtained. The reclining feature allows adjustment of
the seatback for occupants of different sizes
for added comfort and to help obtain proper
seat belt fit. For additional information, see
“Precautions on seat belt usage” (P. 1-11).
Also, the seatback can be reclined to allow
occupants to rest when the vehicle is stopped
and the shift lever is in P (Park).

The recline feature allows adjustment of the
seatback for occupants of different sizes for
added comfort and to help obtain proper seat
belt fit. For additional information, see “Pre-
cautions on seat belt usage” (P. 1-11). Also,
the seatback can be reclined to allow occu-
pants to rest when the vehicle is stopped and
the shift lever is in P (Park).

to make sure it is securely locked.
• Do not ride in a moving vehicle when the
seatback is reclined. This can be danger-
ous. 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 un-

• For the most effective protection when
the vehicle is in motion, the seat should
be upright. Always sit well back and up-
right in the seat and adjust the seat belt
properly. For additional information, see
“Precautions on seat belt usage”
(P. 1-11).
ARMRESTS
The rear bench seat comes equipped with an
armrest. Pull the armrest down as shown.
FLEXIBLE SEATING
WARNING
• Never allow anyone to ride in the cargo
area or on the rear seats when they are in
the fold-down position. In a collision,
people riding in these areas without
proper restraints are more likely to be
seriously injured or killed. •
Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts. Be sure everyone in
your vehicle is in a seat and using a seat
belt properly.
• Do not allow more than one person to use
the same seat belt.
• Do not fold down the rear seats when
occupants are in the rear seat area or any
luggage is on the rear seats.
– Make sure that the seat path is clear
before moving the seat.
– Be careful not to allow hands or feet
to get caught or pinched in the seat.
• Head restraints/headrests should be ad-
justed properly as they may provide sig-
nificant protection against injury in an
accident. Always replace and adjust
them properly if they have been removed
for any reason.
• If the head restraints/headrests are re-
moved for any reason, they should be se-
curely stored to prevent them from caus-
ing injury to passengers or damage to the
vehicle in case of sudden braking or an
accident.

•When returning the seatbacks to the up-
right position, be certain they are com-
pletely secured in the latched position. If
they are not completely secured, passen-
gers may be injured in an accident or sud-
den stop.
• Properly secure all cargo to help prevent
it from sliding or shifting. Do not place
cargo higher than the seatbacks. In a
sudden stop or collision, unsecured cargo
could cause personal injury.
Folding the rear bench seat
To fold the rear bench seat flat for maximum
cargo hauling:
1. Remove any object from the rear seat sit- ting area
2. Move each side of the rear seat com- pletely backwards. For additional infor-
mation, see “Forward and backward”
(P. 1-4).
3. Make sure that the head restraints/ headrests are lowered. For additional in-
formation, see “Lower” (P. 1-11). 4. Stow the rear seat belts in the seat belt
hooks found on the sides of the vehicle.
5. Lift up on the recline lever on the side of the outboard seats or pull the lever on
either side of the cargo area to fold the
seatbacks flat.
• If one of the rear seatbacks does not fold flat completely, move the corre-
sponding Front Power Seat forward,
push up the seatback until it latches in
place and remove the head restraints/
headrests. For additional information,
see “Remove” (P. 1-9).

6. To return the rear bench seats to a seatingposition, push up on the seatback until it
latches in place.WARNING
Head restraints/headrests supplement the
other vehicle safety systems. They may
provide additional protection against in-
jury in certain rear end collisions. Adjust-
able head restraints/headrests must be
adjusted properly, as specified in this sec-
tion. Check the adjustment after someone
else uses the seat. Do not attach anything
to the head restraint/headrest stalk, ex-
cept for genuine INFINITI accessories spe-
cifically tested for use with the vehicle’s
head restraint/headrest stalk. Do not re-
move 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 prop-
erly adjust the head restraint/headrest
before an occupant uses the seating posi-
tion. Failure to follow these instructions
can reduce the effectiveness of the head
restraints/headrests. This may increase
the risk of serious injury or death in a
collision. The illustration shows the seating positions
equipped with head restraints/headrests.

• Adjustable head restraints/headrests havemultiple notches along the stalk(s) to lock
them in a desired adjustment position.
• The non-adjustable head restraints/ headrests have a single locking notch to
secure them to the seat frame.
• Proper Adjustment: – For the adjustable type, align the headrestraint/headrest so the center of your
ear is approximately level with the center
of the head restraint/headrest.
– If your ear position is still higher than the recommended alignment, place the head
restraint/headrest at the highest
position.
• If the head restraint/headrest has been re- moved, ensure that it is reinstalled and
locked in place before riding in that desig-
nated seating position.
