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 INFINITI Direct Response
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).)
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.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as

those used on icy roads or to control dust.
It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see“Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir. When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
.
This vehicle has high voltage DC and AC
systems as well as a 12-volt system. DC
and AC high voltage is very dangerous
and can cause severe burns and electric
shock that may result in serious injury or
death.
. Never touch, disassemble, remove or
replace the high voltage parts, har-
nesses and their connectors. High vol-
tage cables are orange. Touching,
disassembling, removing or replacing
those parts and harnesses can cause
severe burns or electric shock that may
result in serious injury or death.
. Never try to remove the service plug
located in the trunk room. The service
plug is used only when the vehicle is
serviced by trained technicians wearing
personal protection equipment and is
part of the high voltage system. Touch- ing the service plug can cause severe
burns or electric shock that may result in
serious injury or death.
. The INFINITI Direct Response Hybrid
®
System uses high voltage up to 408
volts. The system can be hot while and
after starting. Be careful of both the high
voltage and the high temperature. Obey
the caution labels attached to the
vehicle.
. Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from
moving. Move the shift lever to P (Park).
. Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
. The engine can start at any time without
warning when the hybrid system is in
the READY to drive mode. If you must
work with the hybrid system in the
READY to drive mode, keep your hands,
clothing, hair and tools away from fans,
belts and any other parts that can move.
. It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.

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.
