CAUTION
If the gauge indicates engine coolant
temperature near the hot (H) end of the
normal range, reduce vehicle speed to
decrease temperature. If gauge is over the
normal range, stop the vehicle as soon as
safely possible. If the engine is overheated,
continued operation of the vehicle may
seriously damage the engine. See“If your
vehicle overheats” in the“6. In case of
emergency” section for immediate action
required.

WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
6. Visually check drive belts for damage orlooseness. Also check if the cooling fan
is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking or the cooling fan does
not run, stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
7. After the engine cools down, check thecoolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired at the nearest INFINITI
retailer.
If needed, Roadside Assistance is avail-
able. Please see your Warranty Information
Booklet or Roadside Assistance I.D. Card
for the toll-free number to call (U.S.) or

8-6Maintenance and do-it-yourself
CAUTION
.Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
. Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, coolant, and/or other vehicle fluids
can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
This “8. Maintenance and do-it-yourself”
section gives instructions regarding only
those items which are relatively easy for an
owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” in the“9.
Technical and consumer information” sec-
tion.)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and could affect your warranty coverage.
If in
doubt about any servicing, we recommend
that it be done by an INFINITI retailer.

GUID-322FC0CD-1857-4918-A8CD-01894CD8502C
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” in the“6. In case of
emergency” section of this manual.
. The radiator is equipped with a pressure
type radiator cap. To prevent engine
damage, use only a genuine NISSAN
radiator cap.
CAUTION
.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.
. Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause
damage to the engine, transmission
and cooling system.

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
properly. Check your local regulations.

Check the fluid level in the reservoir. If the
fluid is below the MIN line
*2or the brake
warning light comes on, add Genuine
NISSAN Super Heavy Duty Brake Fluid or
equivalent DOT 3fluid up to the MAX line

WARNING
Antifreeze is poisonous and should be
stored carefully in marked containers out
of the reach of children.
Fill the window washer fluid reservoir
periodically. 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
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 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 window washer reser-
voir tank.
. Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the window washer reservoir tank.
