Seat belt hook
When the seat belt is not in use and when
folding down the rear seats, hook the rear
seat belts on the seat belt hooks.
SEAT BELT EXTENDERS
If, because of body size or driving position, it
is not possible to properly fit the lap/shoulder
belt and fasten it, an extender that is compat-
ible with the installed seat belts is available
for purchase. The extender adds approxi-
mately 8 in (200 mm) of length and may be
used for all seating positions.Seat belt extenders are available for the:
∙ Driver and front passenger seating posi- tions
∙ Rear seating positions
It is recommended that you visit an INFINITI
retailer for assistance with purchasing an ex-
tender if an extender is required.
WARNING
∙ Only INFINITI seat belt extenders, made by the same company which made the
original equipment seat belts, should be
used with INFINITI seat belts.
∙ Adults and children who can use the stan- dard seat belt should not use an extender.
Such unnecessary use could result in seri-
ous personal injury in the event of an
accident.
∙ Never use seat belt extenders to install child restraints. If the child restraint is
not secured properly, the child could be
seriously injured or killed in a collision or a
sudden stop.
SEAT BELT MAINTENANCE
∙ To clean the seat belt webbing, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or car-
pet. Then wipe with a cloth and allow the
seat belts to dry in the shade. Do not
allow the seat belts to retract until they
are completely dry.
∙ If dirt builds up in the shoulder belt guide
of the seat belt anchors, the seat belts
may retract slowly. Wipe the shoulder
belt guide with a clean, dry cloth.
∙ Periodically check to see that the seat
belt and the metal components, such as
buckles, tongues, retractors, flexible
wires and anchors, work properly. If loose
parts, deterioration, cuts or other dam-
age on the webbing is found, the entire
seat belt assembly should be replaced.

tensioner systems may not operate properly.
They must be checked and repaired. It is rec-
ommended that you visit an INFINITI retailer
for this service.
WARNING

others, have your vehicle checked as soon
as possible. It is recommended that you

The front air bags, side air bags, curtain air
bags, knee air bags and pretensioner(s) are
designed to inflate on a one-time-only basis.
As a reminder, unless it is damaged, the
supplemental air bag warning light remains
illuminated after inflation has occurred.

placed as soon as possible. It is recom-
mended that you visit an INFINITI retailer for
this service.
When maintenance work is required on the
vehicle, the front air bags, side air bags, cur-
tain air bags, knee air bags, pretensioner(s)
and related parts should be pointed out to the
person performing the maintenance. The ig-
nition switch should always be in the LOCK
position when working under the hood or
inside the vehicle.
WARNING

bag module will not function again and
must be replaced. Additionally, the acti-
vated pretensioner(s) must also be re-
placed. The air bag module and preten-
sioner(s) should be replaced. It is
recommended that you visit an INFINITI
retailer for this service. However, the air
bag module and pretensioner(s) cannot

High Beam Assist indicatorlight (green)
This indicator light illuminates when the
headlights come on while the headlight
switch is in the AUTO position with the high
beams selected. This indicates that the high
beam assist is operational.
For additional information, refer to “Head-
light switch” in this section.
High beam indicator light(blue)
This blue light comes on when the headlight
high beams are on and goes out when the
low beams are selected.
The high beam indicator light also comes on
when the passing signal is activated.
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 malfunc-
tion. 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 gal-
lons (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 additional information, refer to “Readi-
ness for Inspection/Maintenance (I/M) test”
in the “Technical and consumer information”
section of this manual. Operation
The MIL will come on in one of two ways:
∙ MIL on steady — An emission control sys- tem malfunction has been detected.
Check the fuel-filler cap if the Loose Fuel
Cap warning appears in the vehicle infor-
mation display. If the fuel-filler cap is
loose or missing, tighten or install the cap
and continue to drive the vehicle.
The
light should turn off after a
few driving trips. If the
light does
not turn off after a few driving trips, have
the vehicle inspected. It is recommended
that you visit an INFINITI retailer for this
service. You do not need to have your
vehicle towed to the retailer.
∙ MIL blinking — An engine misfire has been detected which may damage the emis-
sion control system. To reduce or avoid
emission control system damage:
– do not drive at speeds above 45 mph (72 km/h).
– avoid hard acceleration or decelera- tion.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.
Instruments and controls2-17

When the vehicle speed lowers to less than
approximately 16 mph (25 km/h), the head-
light uses the low beam.
To turn off the High Beam Assist system, turn
the headlight switch to the
position or
select the low beam position by placing the
lever in the neutral position.
Ambient image sensor maintenance
The ambient image sensor
1for the High
Beam Assist system is located in front of the
inside mirror. To maintain the proper opera-
tion of the High Beam Assist system and
prevent a system malfunction, be sure to ob-
serve the following:
∙ Always keep the windshield clean.
∙ Do not attach a sticker (including trans- parent material) or install an accessory
near the ambient image sensor. ∙ Do not strike or damage the areas around
the ambient image sensor. Do not touch
the sensor lens that is located on the
ambient image sensor.
If the ambient image sensor is damaged due
to an accident, it is recommended that you
visit an INFINITI retailer.
Battery saver system
The battery saver system automatically turns
off the ignition after a period of time when
the ignition switch is left in the AUTO ACC or
ON position.
The battery saver system automatically turns
off the following lights after a period of time
when the ignition switch is placed in the OFF
position and the doors are closed:
∙ Headlights, when the headlight switch is in the
orposition
∙
Interior lights, when left in the ON position
CAUTION
Even though the battery saver feature au-
tomatically turns off the headlights after a
period of time, you should turn the head-
light switch to the OFF position when the
engine is not running to avoid discharging
the vehicle battery.
