CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant level
is below MIN
, open the reservoir tank cap
and add coolant up to the MAXlevel. If the
reservoir tank is empty, check the coolant
level in the radiator when the engine is cold.
If there is insufficient coolant in the radiator,
fill the radiator with coolant up to the filler
opening and also add it to the reservoir tank
up to the MAX level
.
Tighten the cap securely after adding engine
coolant. If the cooling system requires coolant fre-
quently, have it checked. It is recommended
you visit an INFINITI retailer for this
service.
CHANGING ENGINE COOLANT
It is recommended that major cooling system
repairs be performed by an INFINITI retailer.
The service procedures can be found in the
appropriate INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
.
To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
. Never remove the radiator cap when
the engine is hot. Serious burns could
be caused by high pressure fluid
escaping from the radiator.
. 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 reach of children
and pets. Engine coolant must be disposed of prop-
erly. Check your local regulations.

CHECKING INVERTER COOLANT
LEVEL
Check the coolant level in the reservoir when
the engine and inverter are cold. If the
coolant level is below the MIN level
, add
coolant to the MAX level.
If the inverter cooling system frequently
requires coolant, have it checked. It is
recommended you visit an INFINITI retailer
for this service.
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 prop-
erly. Check your local regulations.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.
5. Remove the dipstick again and check the oil level. It should be within the range
.
If the oil level is below, remove the oil
filler cap and pour recommended oil

better cleaning. In the winter season, add a
windshield washer antifreeze. Follow the
manufacturer’s instructions for the mixture
ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of window washer fluid.
Recommended fluid is Genuine NISSAN
Windshield Washer Concentrate Cleaner &
Antifreeze or equivalent.
CAUTION
.Do not substitute engine anti-freeze
coolant for window washer solution.
This may result in damage to the
paint.
. Do not fill the window washer re-
servoir tank with washer fluid con-
centrates at full strength. Some
methyl alcohol based washer fluid
concentrates may permanently stain
the grille if spilled while filling the
window washer reservoir tank.
. Pre-mix washer fluid concentrates
with water to the manufacturer’s
recommended levels before pouring
the fluid into the window washer
reservoir tank. Do not use the win-
dow washer reservoir tank to mix the washer fluid concentrate and water.JVM0039X
The 12-volt batteryis located on the left
hand side of the trunk behind an access
panel.
. Keep the battery surface clean and dry.
Clean the battery with a solution of
baking soda and water.
. Make certain the terminal connections
are clean and securely tightened.
. If the vehicle is not to be used for 30 days
or longer, disconnect the negative (-)
battery terminal cable to prevent dis-
charge.
NOTE:
Care should be taken to avoid situations
that can lead to potential 12-volt battery

9-4Maintenance and schedules
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 tem-
peratures 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 conditions
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 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, immediately have
the exhaust system inspected. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting and
driving” (P.5-4) 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 level: 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
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, 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 sub-
stances, 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 accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir.
