CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir when the
engine is cold. If the coolant level is below the
MIN level
s1, open the reservoir cap and add
coolant up to the MAX level
s2. If the reservoir
is empty, check the coolant level in the radiator
when the engine is cold.
For VK45DE engine model, remove the engine
cover by removing the 4 clips
sA.
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 up to the MAX
level
s2.
If the cooling system frequently requires cool-
ant, have it checked by an INFINITI retailer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by an INFINITI retailer. The service pro-
cedures can be found in the appropriate INFINITI
Service Manual.
Improper servicing can result in reduced heater
performance and engine overheating.
WARNING
c To avoid the danger of being scalded, never
change the coolant when the engine is hot.
c Never remove the radiator cap when the en-
gine is hot. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
c Avoid direct skin contact with used coolant.
If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as
possible.
c Keep coolant out of reach of children and
pets.
Engine coolant must be disposed of properly.

cally. Add window washer fluid when the low
window washer fluid warning light comes on.
To fill the window washer fluid reservoir, lift the
cap off the reservoir tank and pour the window
washer fluid into the tank opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a wind-
shield washer antifreeze. Follow the manufac-
turer's instructions for the mixture ratio.
Refill the reservoir more frequently when driv-
ing conditions require an increased amount of
window washer fluid.Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Antifreeze
or equivalent.
CAUTION
c
Do not substitute engine anti-freeze coolant
for window washer solution. This may result
in damage to the paint.
c Do not fill the window washer reservoir tank
with washer fluid concentrates at full
strength. Some methyl alcohol based
washer fluid concentrates may permanently
stain the grille if spilled while filling the win-
dow washer reservoir tank.
c Pre-mix washer fluid concentrates with wa-
ter to the manufacturer's recommended lev-
els 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. c

soda and water.
c Make certain the terminal connections are
clean and securely tightened.
c If the vehicle is not to be used for 30 days or
longer, disconnect the negative ( 2) battery
terminal cable to prevent discharging it.
WARNING
c Do not expose the battery to flames or elec-
trical sparks. Hydrogen gas generated by
the battery is explosive. Do not allow battery
fluid to contact your skin, eyes, fabrics, or
painted surfaces. After touching a battery or
battery cap, do not touch or rub your eyes.
Thoroughly wash your hands. If the acid con-
tacts your eyes, skin or clothing, immedi-
ately flush with water for at least 15 minutes
and seek medical attention.
c Do not operate the vehicle if the fluid in the
battery is low. Low battery fluid can cause a
higher load on the battery which can gener-
ate heat, reduce battery life, and in some
cases lead to an explosion.
c When working on or near a battery, always
wear suitable eye protection and remove all
jewelry.SDI1829
