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 HybridTM
System warning light
When the ignition switch is in the "ON"
position, the Direct Response HybridTM
System warning light illuminates. After starting the hybrid system, 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.
Distance Control Assist (DCA)
system warning light (orange; if so
equipped)
This light comes on if there is a malfunc-
tion in the Distance Control Assist (DCA)
system.
If the warning light illuminates, park the
vehicle in a safe place. Stop the hybrid
system, restart the hybrid system, resume driving and turn on the DCA system again.
If it is not possible to turn on the system
or the warning light stays on, it may
indicate that the system is malfunctioning.
Although the vehicle is still driveable
under normal conditions, have the vehicle
checked at an INFINITI retailer.
Engine oil pressure warning
light
This light warns of low engine oil pressure.
If the light flickers or comes on during
normal driving, pull off the road in a safe

by warranty. Turn off the engine as soon as
it is safe to do so.
High temperature warning
light
When the ignition switch is in the ON
position, the high temperature warning
light illuminates and then turns off. This
indicates that the high temperature sensor
in the engine coolant system is opera-
tional.
CAUTION
If the high temperature warning light
illuminates when the ignition switch is in
the ON position, it may indicate the engine
temperature is extremely high.
Stop the vehicle safety as soon as possible.
If the vehicle is overheated, continuing
vehicle operation may seriously damage
the engine. (See “If your vehicle overheats”
in the “6. In case of emergency” section for
the immediate action required.)
Hybrid EPS (Electrical Power
Steering) warning light
When the ignition switch is in the ON
position, the Hybrid EPS (Electrical Power
Steering) warning light illuminates. After
starting the hybrid system, the Hybrid EPS
warning light turns off. This indicates that

operational.
If the Hybrid EPS warning light illuminates
while the hybrid system is running, it may
indicates the Hybrid EPS system is not
functioning properly and may need servi-
cing. Have the Hybrid EPS system checked
by an INFINITI retailer.
When the Hybrid EPS warning light illumi-
nates with the hybrid system 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. However, if the steering wheel
operation is still performed, the Hybrid EPS
may stop and the Hybrid EPS warning light
will illuminate. Place the ignition switch in
the OFF position. For a while after it
refrains from the steering wheel control,
the temperature of the Hybrid EPS system will go down and the power assist level will
return to normal after starting the hybrid
system. The Hybrid EPS warning light will
go off.
Intelligent Cruise Control (ICC)
system warning light (orange; if so
equipped)
This light comes on if there is a malfunc-
tion in the Intelligent Cruise Control (ICC)
system.
If the warning light comes on, park the
vehicle in a safe place. Stop the hybrid
system, restart the hybrid system, resume
driving and set the ICC system again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the

that the system control is temporarily
unavailable.
When the IBA off indicator light illuminates
with the warning chime sound while the
IBA system is turned on, this light indicates
that the system may not be functioning
properly. Park the vehicle in a safe place.
Check to see if the laser sensor is clean.
Stop the hybrid system, then restart the
hybrid system.
If the IBA off indicator light illuminates
after following the procedures above, it may indicate that the system or Active
Trace Control (if so equipped) is malfunc-
tioning. Although the vehicle is still drive-
able under normal conditions, have the
vehicle checked at an INFINITI retailer. (See
“Intelligent Brake Assist (IBA) system”
in
the “5. Starting and driving” section and
“Vehicle Dynamic Control (VDC) system” in
the “5. Starting and driving” section.)Lane Departure Prevention
(LDP) ON indicator light (green; if so
equipped)

Warning (LDW) system/Lane Departure
Prevention (LDP) system” in the“5. Start-
ing and driving” section.
Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks when the ignition switch is
in the ON position, 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 (14 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)” in
the “9. Technical and consumer informa-
tion”.)
