EXTERIOR FRONT

Troubleshooting:
If you think the front passenger air bag
status light is incorrect:
1. If the light is ON with an adult occupyingthe front passenger seat:
.Occupant is a small adult - the air bag
status light is functioning as intended.
The front passenger air bag is sup-
pressed.
However, if the occupant is not a small
adult, then this may be due to the
following conditions that may be inter-
fering with the weight sensors:
.Occupant is not sitting upright, lean- ing against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the
floor.
.A child restraint or other object press-
ing against the rear of the seatback.
.A rear passenger pushing or pulling onthe back of the front passenger seat.
.Forcing the front seat or seatbackagainst an object on the seat or floor
behind it.
.An object placed under the front
passenger seat.
.An object placed between the seat cushion and center console or be-
tween the seat cushion and the door. If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions.
Restart the vehicle and wait 1 minute.
NOTE: A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still ON after this, the
person should be advised not to ride in
the front passenger seat and the vehicle
should be checked as soon as possible. It
is recommended you visit an INFINITI
retailer for this service.
2. If the light is OFF with a small adult, child or child restraint occupying the front
passenger seat:
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
.Small adult or child is not sittingupright, leaning against the seatback,
and centered on the seat cushion with
his/her feet comfortably extended to
the floor.
.The child restraint is not properly
installed as outlined in “Child re-
straints” (P.1-22).
.An object weighing over 9.1 lbs (4 kg) hanging on the seat or placed in the seatback pocket.
.A child restraint or other object press-
ing against the rear of the seatback.
.A rear passenger pushing or pulling on
the back of the front passenger seat.
.Forcing the front seat or seatbackagainst an object on the seat or floor
behind it.
.An object placed under the frontpassenger seat.
.An object placed between the seat
cushion and center console.
.The front passenger seat head re-straint contacting the roof.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions.
Restart the vehicle and wait 1 minute.
NOTE: A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still OFF after this, the small
adult, child or child restraint should be
repositioned in the rear seat and the
vehicle should be checked by an INFINITI
retailer as soon as possible.
3. If the light is OFF with no front passen- ger and no objects on the front passen-

CHECKING LIGHTS
With all doors closed, apply the parking
brake, fasten the seat belts and place the
ignition switch in the ON position without
starting the engine. The following lights (if
so equipped) will come on:
,or,,,
The following lights (if so equipped) will
come on briefly and then go off:
,or,,,
If any light does not come on or operates in a
way other than described, it may indicate a
burned-out bulb and/or a system malfunc-
tion. It is recommended you have the system
checked by an INFINITI retailer.
WARNING/INDICATOR LIGHTS
(red)
See “Vehicle information display” (P.2-18).
orBrake warning light
This light functions for both the parking
brake and the foot brake systems.
Parking brake indicator:
When the ignition switch is 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. If brake fluid is necessary, add fluid and have the
system checked. It is recommended you
have this service performed by an
INFINITI retailer. (See “Brake fluid”
(P.8-10).)
2. If the brake fluid level is correct, have the warning system checked. It is recom-
mended you have this service performed
by an INFINITI retailer.
Anti-lock Braking System (ABS) warning
indicator:
When the parking brake is released and the
brake fluid level is sufficient, if both the
brake warning light and the Anti-lock Brak-
ing System (ABS) warning light illuminate, it
may indicate the ABS is not functioning
properly. Have the brake system checked,
and if necessary repaired. It is recommended
you visit an INFINITI retailer for this service.
(See “Anti-lock Braking System (ABS) warn-
ing light” (P.2-13).)
WARNING
. Your brake system may not be work-
ing properly if the warning light is on.
Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for re-
pairs. Otherwise, have your vehicle
towed because driving it could be
dangerous.
. Pressing the brake pedal with the
engine stopped and/or low brake
fluid level may increase your stopping
distance 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. It is
recommended you visit an INFINITI
retailer for this service.
Charge warning light
If the light comes on while the engine is
running, it may indicate the charging system
is not functioning properly. Turn the engine

If an ABS malfunction occurs, the anti-lock
function is turned off. The brake system then
operates normally, but without anti-lock
assistance. (See “Brake system” (P.5-125).)
Forward Emergency Braking
(FEB) system 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 FEB system is
set to OFF on the lower display.
If the light illuminates when the FEB system
is ON, it may indicate that the system is
unavailable. See “Forward Emergency Brak-
ing (FEB)” (P.5-102) for more details.
Front passenger air bag status
light

operation, see “INFINITI Advanced Air Bag
System (front seats)” (P.1-48).
Low fuel warning light
This light illuminates when the fuel in the
tank is getting low. Refuel as soon as it is
convenient, preferably before the fuel gauge
reaches the 0 (empty) position. There will be a small reserve of fuel remain-
ing in the tank when the fuel gauge reaches
the 0 position.
Low tire pressure warning light
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors
the tire pressure of all tires except the spare
tire (if so equipped).
The low tire pressure warning light warns of
low tire pressure and flat tire (if so equipped)
or indicates that the TPMS is not functioning
properly.
After the ignition switch is placed in the ON
position, this light illuminates for about 1
second and turns off.
Low tire pressure warning:
If the vehicle is being driven with low tire
pressure, the warning light will illuminate.
The “Tire Pressure Low - Add Air” warning
also appears in the vehicle information dis-
play.
When the low tire pressure warning light
illuminates, you should stop and adjust the
tire pressure to the recommended COLD tire
pressure shown on the Tire and Loading
Information label. The low tire pressure
warning light does not automatically turn
off when the tire pressure is adjusted. After
the tire is inflated to the recommended

power steering checked by an INFINITI
retailer.
When the power steering warning light
illuminates 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.

when the VDC system is turned on, this light
alerts the driver to the fact that the VDC
system’s fail-safe mode is operating, for
example the VDC, active trace control func-
tion, Brake Force Distribution or hill start
assist system may not be functioning prop-
erly. Have the system checked. It is recom-
mended you visit an INFINITI retailer for this
service. If a malfunction occurs in the
