CAUTION
.Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
. To avoid the danger of being scalded,
never remove the radiator cap while the
engine is still hot. When the radiator cap
is removed, pressurized hot water will
spurt out, possibly causing serious
injury.
. Do not open the hood if steam is coming
out.
If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc., take
the following steps:
1. Move the vehicle safely off the road,
apply the parking brake and move the
selector lever to the P (Park) position.
Do not turn the INFINITI Direct Re-
sponse Hybrid
TMSystem off.
2. Turn off the climate control. Open all the windows, move the heater or air
conditioner temperature control to maximum hot and fan control to high
speed.
3. If engine overheating is caused by climbing a long hill on a hot day, run
the engine at a fast idle (approximately
1,500 rpm) until the temperature gauge
indication returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off
the hybrid system.) Do not open the
hood further until no steam or coolant
can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
6. Also check if the cooling fan is running. The radiator hoses and radiator should
not leak water. If coolant is leaking or
the cooling fan does not run, stop the
hybrid system.
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.

able. Please see your Warranty Information

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 anti-freeze 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” 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
.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 manufacture’s instruc-
tions to maintain minimum antifreeze
protection to −348F(−378C). The use of
other types of coolant solutions other
than Genuine NISSAN Long Life Anti-
freeze/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 nondis-
tilled water will reduce the life expec-
tancy of the factory-fill coolant. Refer to
the INFINITI Service and Maintenance
Guide for more details.

CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below MIN
*2, open the reservoir
tank cap and add coolant up to the MAX
*1
level. 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 requires coolant
frequently, 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 reach of children and
pets.
Engine coolant must be disposed of
properly. Check your local regulations.

The inverter 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 inverter
cooling system additives are not neces-
sary.
WARNING
.Never remove the coolant reservoir cap
when the engine and inverter are hot.
Wait until the engine and inverter cool
down. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
. The inverter reservoir is equipped with a
pressure type cap. To prevent engine and
inverter damage, use only a genuine
NISSAN inverter reservoir 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 manufatururer’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 inverter cooling sys-
tem.
. The life expectancy of the factory-fill
coolant is 125,000 miles (200,000 km)
or 15 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 additives in the coolant
such as radiator sealer in the cooling
system. This may cause damage to
electrical equipment such as the motor
and inverter, and also to engine and
transmission.
