WARNING
●After adjustment, release the adjust-
ment button and try to move the shoul-
der belt anchor up and down to make
sure it is securely fixed in position.
● The shoulder belt anchor height should
be adjusted to the position best for you.
Failure to do so may reduce the effec-
tiveness of the entire restraint system
and increase the chance or severity of
injury in an accident.
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 is available which is
compatible with the installed seat belts. The ex-
tender adds approximately 8 in (200 mm) of
length and may be used for either the driver or
front passenger seating position. See an INFINITI
dealer for assistance 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
standard seat belt should not use an
extender. Such unnecessary use could
result in serious 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 in a collision or a sud-
den stop.
SEAT BELT MAINTENANCE
● To clean the seat belt webbing, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or carpet.
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 damage on the
webbing is found, the entire seat belt as-
sembly should be replaced.

SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displaying
in the instrument panel, moni-
tors the circuits of the supplemental front-impact
air bag, front seat-mounted side-impact supple-
mental air bag, roof-mounted curtain side-impact
and rollover supplemental air bag and seat belt
pretensioner systems. The monitored circuits in-
clude the Air bag Control Unit (ACU) , crash zone
sensor, satellite sensors, rollover sensor, occu-
pant classification system, front air bag modules,
side air bag modules, curtain and rollover air bag
modules, pretensioners and all related wiring. When the ignition switch is placed in the ON or
START position, the supplemental air bag warn-
ing light illuminates for about 7 seconds and then
turns off. This means the system is operational.
If any of the following conditions occur, the front
air bag, side air bag, curtain and rollover air bag
and pretensioner systems need servicing:
● The supplemental air bag warning light re-
mains on after approximately 7 seconds.
● The supplemental air bag warning light
flashes intermittently.
● The supplemental air bag warning light does
not come on at all.
Under these conditions, the front air bag, side air
bag, curtain and rollover air bag or pretensioner
systems may not operate properly. They must be
checked and repaired. Take your vehicle to the
nearest INFINITI dealer.
WARNING
If the supplemental air bag warning light
is on, it could mean that the front air bag,
side air bag, curtain and rollover air bag
and/or pretensioner systems will not op-
erate in an accident. To help avoid injury
to yourself or others, have your vehicle
checked by an INFINITI dealer as soon as
possible.
Repair and replacement procedure
The front air bags, side air bags, curtain and
rollover air bags and pretensioners 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. Repair and replacement of these
supplemental air bag systems should be done
only by an INFINITI dealer.
When maintenance work is required on the ve-
hicle, the front air bags, side air bags, curtain and
rollover air bags, pretensioners and related parts
should be pointed out to the person performing
the maintenance. The ignition switch should al-
ways be in the LOCK position when working
under the hood or inside the vehicle.

CAUTION
●This gauge is not designed to indicate
low engine oil level. Use the dipstick to
check the oil level. (See “Engine oil” in
the “Maintenance and do-it-yourself”
section.)
● If the gauge reading does not move with
the proper amount of engine oil, have
the vehicle checked by an INFINITI
dealer. Continued vehicle operation in
such a condition could cause serious
damage to the engine.
VOLTMETER
When the ignition switch is placed in the ON
position, the voltmeter indicates the battery volt-
age. When the engine is running, it indicates the
generator voltage.
While cranking the engine, the volts drop below
the normal range. If the reading is not in the
normal range (11 – 15 volts)
1while the engine
is running, it may indicate that the charging sys-
tem is not functioning properly. Have the system
checked by an INFINITI dealer.

Parking brake indicator
When the ignition switch is placed in the ON
position, the light comes on when the parking
brake is applied.
Low brake fluid warning light
When the ignition switch is in the ON position,
the light warns of a low brake fluid level. If the light
comes on while the engine is running with the
parking brake not applied, stop the vehicle and
perform the following:1. Check the brake fluid level. Add brake fluid as necessary. See “Brake fluid” in the “Main-
tenance and do-it-yourself” section of this
manual.
2. If the brake fluid level is correct, have the warning system checked by an INFINITI
dealer.
WARNING
●Your brake system may not be working
properly if the warning light is on. Driv-
ing could be dangerous. If you judge it
to be safe, drive carefully to the nearest
service station for repairs. Otherwise,
have your vehicle towed because driv-
ing it could be dangerous. ●
Pressing the brake pedal with the en-
gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel.
● If the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked at an
INFINITI dealer.
Charge warning light
If this light comes on while the engine is running,
it may indicate the charging system is not func-
tioning properly. Turn the engine off and check
the generator belt. If the belt is loose, broken,
missing, or if the light remains on, see an INFINITI
dealer immediately.
CAUTION
● Do not ground electrical accessories
directly to the battery terminal. Doing
so will bypass the variable control sys-
tem and the vehicle battery may not
charge completely. Refer to “Variable
voltage control system” in the “Mainte-
nance and do-it-yourself” section later
in this manual. ●
Do not continue driving if the generator
belt is loose, broken or missing.
Check suspension warning
light
This light may indicate a malfunction in the auto-
leveling suspension.
For additional information, refer to “Jacking up
vehicle and removing the damaged tire” in the “In
case of emergency” section of this manual.
Engine oil pressure low/Engine coolant temperature
high warning light
This light warns of low engine oil pressure or high
engine coolant temperature.
If the light flickers or comes on during normal
driving, pull off the road in a safe area, stop the
engine and allow it to cool. If the light remains on
after checking the oil and coolant, stop the en-
gine immediately and call an INFINITI dealer or
other authorized repair shop.
This light is not designed to indicate a low
oil or low coolant level. Check the oil level
with the dipstick and check the coolant level on
the reservoir. See “Engine oil” and “Checking
engine coolant level” in the “Maintenance and

Malfunction Indicator Light(MIL)
If this indicator light comes on steady or blinks
while the engine is running, it may indicate a
potential emission control malfunction.
The Malfunction Indicator Light 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 sys-
tem inspection/maintenance test. See “Readi-
ness for inspection/maintenance (I/M) test” in the
“Technical and consumer information” section of
this manual. Operation
The malfunction indicator light will come on in
one of two ways:
● Malfunction indicator light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap. 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 by an INFINITI dealer. You
do not need to have your vehicle towed to
the dealer.
● Malfunction indicator light blinking — An en-
gine misfire has been detected which may
damage the emission control system. To re-
duce or avoid emission control system dam-
age:
– do not drive at speeds above 45 MPH (72 km/h) .
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed. The malfunction indicator light may stop blinking
and come on steady. Have the vehicle inspected
by an INFINITI dealer. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
Security indicator light
This light blinks whenever the ignition switch is in
the LOCK, OFF or ACC position. This function
indicates the security system equipped on the
vehicle is operational.
For additional information, see “Security sys-
tems” later in this section.
Slip indicator light
This indicator light will blink when the traction
control system is limiting wheel spin. Slippery
road conditions may exist if the slip indicator
blinks on. If this happens, adjust your driving
accordingly.
