WARNING
The engine cooling system is filled at the
factory with a high-quality, year-round,
antifreeze coolant solution. The antifreeze
solution contains rust and corrosion inhibi-
tors, therefore additional cooling system
additives are not necessary.
•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. For additional information on
precautions, refer to "If your vehicle
overheats" in the "6. In case of emer-
gency" section
•The engine coolant reservoir tank is
equipped with a pressure type cap. To
prevent engine damage, use only a
genuine INFINITI pressure cap.
CAUTION
•Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.

•When adding or replacing coolant, be
sure to use only INFINITI Genuine En-
gine Coolant, BASF Glysantin G40 or
equivalent in its quality. The use of other
types of engine coolant may damage the
engine cooling system.
CHECKING ENGINE COOLANT
LEVEL
NOTE
The coolant level must only be checked and
corrected when the engine is cold.
1. Park the vehicle on a level surface.
Only check the coolant level if the vehicle
is on a level surface and the engine is cold. 2. Slowly turn cap
1half a turn counter-
clockwise to allow excess pressure to es-
cape.
3. Turn cap
1further counter-clockwise
and remove it.
If the coolant is at the level of marker bar
3in the filler neck when cold, there is
enough coolant in coolant expansion tank
2.
4. If necessary, top up with INFINITI Genu- ine Engine Coolant, BASF Glysantin G40
or equivalent in its quality.
5. Replace cap
1and turn it clockwise as
far as it will go.
If the cooling system frequently requires
coolant, have it checked. It is recommended
that you visit an INFINITI retailer for this
service.
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine
coolant.
Improper servicing can result in reduced
heater performance and engine overheating.
WARNING
•To avoid 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.
