THREE-POINT TYPE SEAT BELT
WITH RETRACTOR
WARNING
• Every person who drives or rides in this
vehicle should use a seat belt at all times.
Children should be in the rear seats and in
an appropriate restraint.
• 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 belt properly. •
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the seat
belt becomes wrapped around a child’s
neck with the ALR mode activated, the
child can be seriously injured or killed if
the seat belt retracts and becomes tight.
This can occur even if the vehicle is
parked. Unbuckle the seat belt to release
the child. If the seat belt cannot be un-
buckled or is already unbuckled, release
the child by cutting the seat belt with a
suitable tool (such as a knife or scissors)
to release the seat belt.

3. Position the lap belt portionlow and snug
on the hips
OBas shown.
4. Pull the shoulder belt portion toward the retractor to take up extra slack
OC. Be sure
the shoulder belt is routed over your
shoulder and across your chest.
The front passenger seat and the rear seating
positions three-point seat belts have two
modes of operation:
• Emergency Locking Retractor (ELR)
• Automatic Locking Retractor (ALR)
The ELR mode allows the seat belt to extend
and retract to allow the driver and passen-
gers some freedom of movement in the seat. The ELR locks the seat belt when the vehicle
slows down rapidly or during certain impacts.
The ALR mode (child restraint mode) locks
the seat belt for child restraint installation.
When the ALR mode is activated, the seat
belt cannot be extended again until the seat
belt tongue is detached from the buckle and
fully retracted. The seat belt returns to the
ELR mode after the seat belt fully retracts.
For additional information, see “Child re-
straints” (P. 1-22).
The ALR mode should be used only for child
restraint installation. During normal seat
belt use by an occupant, the ALR mode
should not be activated. If it is activated, it
may cause uncomfortable seat belt tension.
It can also change the operation of the front
passenger air bag. For additional informa-
tion, see “Front passenger air bag and status
light” (P. 1-51).
WARNING
When fastening the seat belts, be certain
that the seatbacks are completely secured
in the latched position. If they are not com-
pletely secured, passengers may be injured
in an accident or sudden stop.
Unfastening the seat belts
To unfasten the seat belt, press the button on
the buckle
O1. The seat belt automatically
retracts.
Checking seat belt operation
Seat belt retractors are designed to lock seat
belt movement by two separate methods:
• When the seat belt is pulled quickly from the retractor.
• When the vehicle slows down rapidly.

Front passenger air bag
The front passenger air bag and passenger
knee air bag is designed to automatically turn
OFF when the vehicle is operated under
some conditions as described below in accor-
dance with U.S. regulations. If the front pas-
senger air bag and passenger knee air bag is
OFF, it will not inflate in a crash. The driver air
bag and other air bags in your vehicle are not
part of this system.
The purpose of the regulation is to help re-
duce the risk of injury or death from an inflat-
ing air bag to certain front passenger seat
occupants, such as children, by requiring the
air bag to be automatically turned OFF. Cer-
tain sensors are used to meet the
requirements.
The occupant classification sensor in this ve-
hicle is a weight sensor. It is designed to
detect an occupant and objects on the seat
by weight. For example, if a child is in the
front passenger seat, the INFINITI Advanced
Air Bag System is designed to turn the front
passenger air bag OFF in accordance with
the regulations. Also, if a child restraint of the
type specified in the regulations is on the
seat, its weight and the child’s weight can be
detected and cause the air bag to turn OFF.Front passenger seat adult occupants who
are properly seated and using the seat belt as
outlined in this manual should not cause the
front passenger air bag to be automatically
turned OFF. For small adults it may be turned
OFF, however, if the occupant takes his/her
weight off the seat cushion (for example, by
not sitting upright, by sitting on an edge of
the seat, or by otherwise being out of posi-
tion), this could cause the sensor to turn the
air bag OFF. Always be sure to be seated and
wearing the seat belt properly for the most
effective protection by the seat belt and
supplemental air bag.
INFINITI recommends that pre-teens and
children be properly restrained in a rear seat.
INFINITI also recommends that appropriate
child restraints and booster seats be properly
installed in a rear seat. If this is not possible,
the occupant classification sensor is designed
to operate as described above to turn the
front passenger air bag and passenger knee
air bag OFF for specified child restraints as
required by the regulations. Failing to prop-
erly secure child restraints and to use the ALR
mode may allow the restraint to tip or move
in a collision or sudden stop. This can also
result in the front passenger air bag and pas-
senger knee air bag inflating in a crash in-
stead of being OFF. For additional informa-
tion, see “Child restraints” (P. 1-22).If the front passenger seat is not occupied,
the front passenger air bag and passenger
knee air bag is designed not to inflate in a
crash. However, heavy objects placed on the
seat could result in air bag inflation, because
of the object’s weight detected by the occu-
pant classification sensor. Other conditions
could also result in air bag inflation, such as if
a child is standing on the seat, or if two
children are on the seat, contrary to the in-
structions in this manual. Always be sure that
you and all vehicle occupants are seated and
restrained properly.
Using the front passenger air bag status light,
you can monitor when the front passenger air
bag and passenger knee air bag is automati-
cally turned OFF.
If an adult occupant is in the seat but the
front passenger air bag status light is illumi-
nated (indicating that the front passenger air
bag and passenger knee air bag is OFF), it
could be that the person is a small adult, or is
not sitting on the seat properly or not using
the seat belt properly.
If a child restraint must be used in the front
seat, the front passenger air bag status light
may or may not be illuminated, depending on
the size of the child and the type of child
restraint being used. If the air bag status light
is not illuminated (indicating that the front

•When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for approxi-
mately 1 minute. The light will remain on
after 1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit an INFINITI retailer for these
services.
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
• If the vehicle is being driven at speeds of
less than 16 mph (25 km/h), the TPMS
may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.
Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or
blinks while the engine is running, it may indi-
cate a potential emission control
malfunction.
The MIL may also come on steady if the
fuel-filler cap is loose or missing, or if the
vehicle runs out of fuel. Check to make sure
the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3
gallons (11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20
seconds and then blinks for 10 seconds when
the engine is not running, it indicates that the
vehicle is not ready for an emission control
system inspection/maintenance test. For ad-
ditional information, see “Readiness for
Inspection/Maintenance (I/M) test”
(P. 10-32).

Power steering warning
light
WARNING
• If the engine is not running or is turned
off while driving, the power assist for the
steering will not work. Steering will be
harder to operate.
• When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of the
vehicle, but the steering will be harder to
operate. Have the power steering sys-
tem checked. It is recommended that you
visit an INFINITI retailer for this service.
Models with Direct Adaptive Steering®:
When the ignition switch is in the ON posi-
tion, the power steering warning light illumi-
nates. After starting the engine, the power
steering warning light stays on for a few
seconds and turns off. This indicates that
Direct Adaptive Steering is operational. Drive
the vehicle after the power steering warning
light turns off.
If the power steering warning light illumi-
nates while driving, pull off the road to a safe
location and stop the vehicle. If the power
steering warning light turns off, you can drive again. If the power steering warning light
continues to illuminate, have the Direct
Adaptive Steering checked. It is recom-
mended that you visit an INFINITI retailer for
this service. For additional information, see
“Power Steering”. (P. 5-149).
Models with electric power steering:
When the ignition switch is in the ON posi-
tion, the power steering warning light illumi-
nates. After starting the engine, the power
steering warning light turns off. This indicates
the electric power steering is operational.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the electric power steering is not func-
tioning properly and may need servicing. It is
recommended that you have the electric
power steering checked by an INFINITI
retailer.
When the power steering warning light illu-
minates with the engine running, the power
assist to the steering will cease operation but
you will still have control of the vehicle. At this
time, greater steering efforts are required to
operate the steering wheel, especially in
sharp turns and at low speeds. For additional
information, see “Power Steering” (P. 5-149).
Rear Automatic Braking
(RAB) warning light
This light comes on when the ignition switch
is placed in the ON position. It turns off after
the engine is started.
This light illuminates when the RAB system is
turned off in the vehicle information display.
If the light illuminates when the RAB system
is on, it may indicate that the system is un-
available. For additional information, see
“Rear Automatic Braking (RAB)” (P. 5-118).
Slip indicator light
This indicator light will blink when the VDC
system is operating, thus alerting the driver to
the fact that the road surface is slippery and
the vehicle is nearing its traction limits.
You may feel or hear the system working; this
is normal.
The light will blink for a few seconds after the
VDC system stops limiting wheel spin.
