2. If the brake fluid level is correct, havethe warning system checked by an
INFINITI retailer.
Brake system malfunction warning:
If the brake warning light (red) and the
following warning light illuminate at the
same time when the parking brake is
released and the brake fluid level is
sufficient, there may be a malfunction in
the brake system.
. Brake system warning light (yellow)
WARNING
If both the brake system warning light
(yellow) and the brake warning light (red)
illuminate when the parking brake is re-
leased and the hybrid system is on, do not
drive the vehicle. More brake pedal effort
than normal will be required and there will
be a significant reduction in brake perfor-
mance, which could result in an accident.
Immediately stop the vehicle in a safe
location and contact an INFINITI retailer.
A chime sounds if a malfunction occurs in
the brake system power supply. .
Anti-lock Braking System (ABS) warning
light
— Avoid driving at high speed and
sudden braking, and see an INFINITI
retailer as soon as possible for an
inspection.
WARNING
. Your brake system may not be working
properly if the brake warning light (red)
is on. Driving 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 driving it could be dangerous.
. Pressing the brake pedal with the hybrid
system stopped and/or 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
retailer.
Direct Response Hybrid®Sys-
tem warning light
When the ignition switch is in the ON
position, the Direct Response Hybrid®
System (hybrid system) warning light
illuminates. After starting the hybrid sys-
tem, the hybrid system warning light turns
off.
If the hybrid system warning light illumi-
nates while driving, it may indicate that
there is a malfunction in the electric motor
and/or other hybrid system components.
Stop your vehicle immediately and contact
your INFINITI retailer.
If the hybrid system warning light blinks
while driving, it may indicate that the Li-ion
battery charge is low and you cannot
continue to drive.
Do not allow the vehicle to coast when the
Li-ion battery is low or when the hybrid
system warning light blinks while driving.
The engine will not automatically start to
charge the Li-ion battery while the vehicle
is coasting.

Exterior light indicator
This indicator illuminates when the head-
light switch is turned to the AUTO,orposition and the front parking lights,
instrument panel lights, rear combination
lights, license plate lights or headlights are
on. The indicator turns off when these
lights are turned off.
Front fog light indicator light
The front fog light indicator light illumi-
nates when the front fog lights are on. (See
“Fog light switch” (P.2-47).)
Front passenger air bag status
light
The front passenger air bag status light
() located on the instrument panel will
be lit and the passenger front air bag will
be OFF depending on how the front
passenger seat is being used.
For front passenger air bag status light
operation, see “INFINITI Advanced Air Bag
System (front seats)” (P.1-42).
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.2-43).)
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 (MIL)
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 ex-
ists.
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/main-
tenance test. (See
“Readiness for Inspec-
tion/Maintenance (I/M) test (US only)” (P.9-
22).)
Operation:
The malfunction indicator light will come
on in one of two ways:
. Malfunction indicator light on steady —
An emission control system malfunc-
tion 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 by an INFINITI retai-
ler. 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 con-
trol system.
To reduce or avoid emission control
system damage:
