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 engine.) Do not open the hood
further until no steam or coolant can be
seen.
5. Open the engine hood.
WARNINGIf 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 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 the
coolant 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.

smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism: On a fairly steep hill, check that your
vehicle is held securely with the selector
lever in the P (Park) position without
applying any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, see an INFINITI retailer
immediately. Keep the floor mat away from
the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, see an INFINITI
retailer.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.

The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel). Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“ Precautions when starting and driving ”
(P.5-3) for exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water

CHECKING ENGINE COOLANT LEVEL GUID-0A58561D-6ED8-4332-9DEB-68F0F2BD40A6
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
* 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 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.

WARNINGAntifreeze 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. Do not use the window washer reservoir
tank to mix the washer fluid concentrate
and water.
