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
shift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the
windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engineat 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
engine.) 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. Visually check drive belts for damage or
looseness. 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 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 coolingfan can start at any time.
7. After the engine cools down, check the
coolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired. It is recommended you
visit an INFINITI retailer for this service.

.When adding or replacing coolant, be
sure to use only Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
or equivalent. Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is pre-
diluted to provide antifreeze protec-
tion to −34°F (−37°C). If additional
freeze protection is needed due to
weather where you operate your
vehicle, add Genuine NISSAN Long
Life Antifreeze/Coolant (blue) con-
centrate following the directions on
the container. If an equivalent cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is
used, follow the coolant manufac-
ture’s instructions to maintain mini-
mum antifreeze protection to −34°F
(−37°C). The use of other types of
coolant solutions other than Genuine
NISSAN Long Life Antifreeze/Cool-
ant (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/Cool-
ant (blue) (or equivalent coolant),
including Genuine NISSAN Long Life
Antifreeze/ Coolant (green), or theuse of non-distilled water will reduce
the life expectancy of the factory-fill

CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir tank
when the engine is running and after it
reaches normal operating temperature. If
the coolant level is below MIN level
, add
coolant up to the MAX level. If the
reservoir tank is empty, check the coolant
level in the radiatorwhen the engine is cold.
If there is insufficient coolant in the radiator,
fill the radiator with coolant up to the filler
cap above the radiator upper hose opening
and also add it to the reservoir tank up to the
MAX level
. Put on the filler cap above the
radiator upper hose and with the reservoir
cap open, start the engine. Run the engine

until it reaches normal operating tempera-
ture. Add coolant up to the MAX level.
Tighten the cap securely after adding engine
coolant.
If the cooling system requires coolant fre-
quently, have it checked. It is recommended
you visit an INFINITI retailer for this
service.
CHANGING ENGINE COOLANT
It is recommended that major cooling system
repairs be performed by an INFINITI retailer.
The service procedures can be found in the

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 cleaneras soon as possible.
.Keep coolant out of reach of children
and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.The intercooler cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/

year-round anti-freeze and coolant protec-
tion. The antifreeze solution contains rust
and corrosion inhibitors. Additional inter-
cooler cooling system additives are not
necessary.
WARNING
.Never remove the coolant reservoir
cap when the engine is hot. Wait until
the engine cools down. Serious burns
could be caused by high pressure fluid
escaping from the coolant reservoir.
.The intercooler reservoir is equipped
