9-4Maintenance and schedules
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
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).
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 battery discharge
and potential no-start conditions such as:1.Installation or extended use of electro-
nic accessories that consume 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 battery may need to be
charged to maintain 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.
Intercooler 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 engine. 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 anddriving” (P.5-4).)
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.
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.

10-6Technical and consumer information
may cause excessive fuel consumption or
damage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended you visit an
INFINITI retailer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see “Capacities and recommended fluids/
lubricants” (P.10-2). INFINITI recommends
the use of an energy conserving oil in order
to improve fuel economy.
Select only engine oils that meet the Amer-
ican Petroleum Institute (API) certificationor International Lubricant Standardization
and Approval Committee (ILSAC) certifica-
tion and SAE viscosity standard. These oils
have the API certification mark on the front
of the container. Oils which do not have the
specified quality label should not be used as
they could cause engine damage.
Oil additives:
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
