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.
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
area, stop the engine immediatelyand call
an INFINITI retailer or other authorized
repair shop.

securely. Check the belt webbing for cuts,
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

CHECKING INVERTER COOLANT LE-
VEL
Check the coolant level in the reservoir
when the engine and inverter are cold. If
the coolant level is below the MIN level
*B,
add coolant to the MAX level
*A.
If the inverter cooling system frequently
requires coolant, have it checked by an
INFINITI retailer.
CHANGING INVERTER COOLANT
An INFINITI ratailer can change the inverter
coolant. The service procedure can be
found in the INFINITI Service Manual.
Improper servicing can result in inverter
overheating.
WARNING
. To avoid the danger of being scalded,
never change the coolant when the
inverter is hot.
. Never remove the cap when the inverter
is hot. Serious burns could be caused by
high pressure fluid escaping from the
inverter coolant reservoir.
. Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
. Keep coolant out of the reach of children
and pets.
Inverter coolant must be disposed of
properly. Check your local regulations.
