Check the coolant level in 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

.
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 GUID-5414AC03-7904-49CD-BD61-168CF59A9756
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.

WARNING . Do not expose the battery to flames or
electrical sparks. Hydrogen gas gener-
ated by the battery is explosive. Do not
allow battery fluid to contact your skin,
eyes, fabrics, or painted surfaces. After

eyes, skin or clothing, immediately flush
with water for at least 15 minutes and
seek medical attention.
. 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 generate heat, reduce battery life,
and in some cases lead to an explosion.
. When working on or near a battery,
always wear suitable eye protection and
remove all jewelry.
. Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash hands after handling.
