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
.
Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from
moving. For manual transmission mod-
els, move the shift lever to N (Neutral).
For automatic transmission models,
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.
. Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
. If you must work with the engine
running, keep your hands, clothing, hair and tools away from moving fans, belts
and any other moving parts.
. It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
. Always wear eye protection whenever
you work on your vehicle.
. If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
. Never get under the vehicle while it is
supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position and
the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
Maintenance and do-it-yourself8-5
MAINTENANCE PRECAUTIONS

8-8Maintenance and do-it-yourself
The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/Cool-
ant (blue) and 50% water to provide year-
round anti-freeze and coolant protection.
The antifreeze solution contains rust and
corrosion inhibitors. Additional engine
cooling system additives are not neces-
sary.
WARNING
.Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused by
high pressure fluid escaping from the
radiator. See precautions in “If your
vehicle overheats” (P.6-16) of this man-
ual.
. The radiator is equipped with a pressure
type radiator cap. To prevent engine
damage, use only a genuine NISSAN
radiator cap.
CAUTION
.Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause
damage to the engine, transmission
and/or cooling system.
. When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is pre-diluted to
provide antifreeze protection to −348F
(−378C). If additional freeze protection is
needed due to weather where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is used,
follow the coolant manufacturer’ s in-
structions to maintain minimum anti-
freeze protection to −348F(−378C). The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling system. .
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km)
or 7 years. Mixing any other type of
coolant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue), including
Genuine NISSAN Long Life Antifreeze/
Coolant (green), or the use of non-
distilled water will reduce the life
expectancy of the factory-fill coolant.
Refer to the INFINITI Service and Main-
tenance Guide for more details.
ENGINE COOLING SYSTEM

SDI2043
CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir
tank when the engine is cold. If the coolant
level is below the MIN level
*2, open the
reservoir tank cap and add coolant up to
the MAX level
*1. 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
*1.
Tighten the cap securely after adding
engine coolant. If the cooling system frequently requires
coolant, have it checked by an INFINITI
retailer.
CHANGING ENGINE COOLANT
Major cooling system repairs should 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 the reach of children
and pets.
Engine coolant must be disposed of
properly. Check your local regulations.
