Exterior light indicator
This indicator illuminates when the headlight
switch is turned to the AUTO,orposition and the front parking lights, instru-
ment panel lights, rear combination lights,
license plate lights or headlights are on. The
indicator turns off when these lights are
turned off.

For front passenger air bag status light
operation, see “INFINITI Advanced Air Bag
System (front seats)” (P.1-46).
High beam assist indicator
light (if so equipped)
The indicator light illuminates when the
headlights come on while the headlight
switch is in the AUTO position with the high
beam selected. This indicates that the high
beam assist system is operational. (See
“High beam assist” (P.2-36).)
High beam indicator light
This light comes on when the headlight high
beam is on and goes out when the low beam
is selected.
Malfunction Indicator Light
(MIL)
If the malfunction 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 US 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 remains on 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.
(See “Readiness for Inspection/Mainte-
nance (I/M) test (US only)” (P.10-22).)
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 Loose Fuel Cap warning
appears in the vehicle information dis-
play. 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 thelight does not turn off
after a few driving trips, have the vehicle
inspected. It is recommended you visit an
INFINITI retailer for this service. You do
not need to have your vehicle towed to
the retailer.
. Malfunction indicator light blinking — An
engine misfire has been detected which
may damage the emission control sys-
tem.

High beam assist (if so equipped)
The high beam assist system will operate
when the vehicle is driven at speeds of
approximately 22 MPH (35 km/h) andabove. If an oncoming vehicle or leading
vehicle appears in front of your vehicle when
the headlight high beam is on, the headlight

for safe driving operation. The driver
should remain alert at all times,
ensure safe driving practices and
switch the high beams and low beam
manually when necessary.
. The high beam or low beam may not
switch automatically under the fol-
lowing conditions. Switch the high
beam and low beam manually.
— During bad weather (rain, fog, snow, wind, etc.).

vicinity of the vehicle.
— When the headlights of the on- coming vehicle or the leading
vehicle are turned off, when the
color of the light is affected due to
foreign materials on the lights, or when the light beam is out of
position.
— When there is a sudden, contin- uous change in brightness.
— When driving on a road that passes over rolling hills, or a road
that has level differences.
— When driving on a road with many curves.
— When a sign or mirror-like sur- face is reflecting intense light
towards the front of the vehicle.
— When the container, etc. being towed by a leading vehicle is
reflecting intense light.
— When a headlight on your vehicle is damaged or dirty.
— When the vehicle is leaning at an angle due to a punctured tire,
being towed, etc.
. The timing of switching the low beam
and high beam may change under the
following situations.
