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 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.

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

While the LDW and/or LDP system is on,
the light will blink in orange and a warning

Brake Assist (IBA) system is not operating.
When the IBA off indicator light illuminates
while the system is turned on (without the
warning chime sound), this light indicates
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”(P.5-
86) and “Vehicle Dynamic Control (VDC)
system” (P.5-100).)

Prevention (LDP) system” (P.5-21).
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)” (P.9-
20).)
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 dot matrix
liquid crystal display. 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 retailer. 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.

5-100Starting and driving
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, elec-
tric pumps, hydraulic solenoids and a
computer. The computer has a built-in
diagnostic feature that tests the system
each time you start the hybrid system and
move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you
may hear a“clunk”noise and/or feel a
pulsation in the brake pedal. This is normal
and does not indicate a malfunction. If the
computer senses a malfunction, it switches
the ABS off and illuminates the ABS
warning light on the instrument panel.
The brake system then operates normally,
but without anti-lock assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked by an INFINITI retailer.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic
pressure. This action is similar to pumping
the brakes very quickly. You may feel a
pulsation in the brake pedal and hear a
noise from under the hood or feel a
vibration from the actuator when it is
operating. This is normal and indicates
that the ABS is operating properly. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving. The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver
inputs and vehicle motion. Under certain
driving conditions, the VDC system helps
to perform the following functions.
.
Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine or
mortor output to reduce drive wheel
slip based on vehicle speed (traction
control function).
. Controls brake pressure at individual
wheels and engine or motor output to
help the driver maintain control of the
vehicle in the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due
to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.

fraying, wear or damage.
Seats:Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel). 12-volt battery*:
Check the fluid level in
each cell. It should be between the MAX
and MIN lines. Vehicles operated in high
temperatures or under severe condition
require frequent checks of the battery fluid
level.
NOTE:
Care should be taken to avoid situations
that can lead to potential 12-volt battery
discharge and potential no-start condi-
tions such as:
1. Installation or extended use of electro-
nic accessories that consume 12-volt
battery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the 12-volt battery may
need to be charged to maintain 12-volt
battery health.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt is frayed, worn, cracked or oily.
Engine oil level*:
Check the level after
parking the vehicle on a level spot and
turning off the hybrid system. Wait more
than 15 minutes for the oil to drain back
into the oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3) for exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Inverter coolant lebel: Check the coolant
level when the inverter is cold.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the hybrid system off. Check the lines
for proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the

9. Refill engine with recommended oil and install the oil filler cap securely.
CAUTION
The dipstick must be inserted in place to
prevent oil spillage from the dipstick hole
while filling the engine with oil.
See “Capacities and recommended
fuel/lubricants” (P.9-2) for drain and
refill capacity. The drain and refill
capacity depends on the oil tempera-
ture and drain time. Use these specifi-
cations for reference only. Always use
the dipstick to determine the proper
amount of oil in the engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required. 11. Turn the engine off and wait more than
