2011 NISSAN ALTIMA HYBRID coolant level

When the ignition switch is placed in the ON
position, the power steering warning light illumi-
nates. After the Hybrid System is in the READY
mode, the power steering warning light turns off.
This indicates the power steering system is op-
erational.
If the power steering warning light illuminates
while the Hybrid System is in the READY mode, it
may indicate the power steering system is not
functioning properly and may need servicing.
Have the power steering system checked by a
NISSAN dealer.
When the power steering warning light illumi-
nates with the Hybrid System in the READY
mode, there will be no power assist for the steer-
ing but you will still have control of the vehicle. At
this time, greater steering effort is required to
operate the steering wheel, especially in sharp
turns and at low speeds.
See “Power steering” in the “Starting and driving”
section.
Electronically controlled brakewarning light (yellow)
This light functions for both the regenerative
brake and electronically controlled brake sys-
tems. When the ignition switch is placed in the ON
position and the Hybrid System is in the READY
mode, the light stays on for about 2 seconds. If
the light comes on at any other time, it may
indicate the regenerative brake and/or the elec-
tronically controlled brake systems are not func-
tioning properly. Have the system checked by a
NISSAN dealer.
If the hydraulic brake warning light also comes on
with the parking brake not applied, stop the ve-
hicle immediately and call a NISSAN dealer. For
additional information, see
Brake systemin
Starting and Driving section.
WARNING
Your brake system may not be working
properly if both the brake warning light
and electronically controlled brake sys-
tem warning light come on when the Hy-
brid System is in READY mode and the
parking brake is not applied. Driving could
be dangerous. If you judge it to be safe,
drive carefully to the nearest service sta-
tion for repairs. Otherwise, have your ve-
hicle towed because driving could be
dangerous.
Engine oil pressure warning
light
This light warns of low engine oil pressure. If the
light flickers or comes on during normal driving,
pull off the road in a safe area, stop the engine
immediately and call a NISSAN dealer or other
authorized repair shop.
The engine oil pressure warning light is not
designed to indicate a low oil level. Use the
dipstick to check the oil level. See “Engine oil” in
the “Maintenance and do-it-yourself” section of
this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.
High temperature warning light
(red)
When the ignition switch is placed in the ON
position, the high temperature warning light illu-
minates and then turns off. This indicates that the
high temperature sensor in the engine coolant
system is operational.

3. Get out of the vehicle. Look and listen forsteam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn the Hybrid System off.)
Do not open the hood further until no steam
or coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine and/or inverter, stand clear to pre-
vent getting burned.
5. 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,
the water pump belt is missing or loose, or
the cooling fan does not run, turn the Hybrid
System off.
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 or engine
cooling fan can start at any time. 6. After the engine and inverter cools down,
check the coolant level in the engine and
inverter coolant reservoir tank with the en-
gine running. Add coolant to the engine and
inverter coolant reservoir tank if necessary.

ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimes Make sure all
warning lights and chimes are operating properly.
Windshield wiper and washer* Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defroster Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Brake fluid level* Make sure that the brake fluid
level is between the MIN and MAX lines on the
reservoir.
Electronically controlled Continuously
Variable Transmission (eCVT) fluid* Check
under the vehicle for leaks after the vehicle has
been parked for a while.
Engine coolant level* Check the coolant level
when the engine is cold. Engine drive belts*
Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level* Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 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, immediately have the exhaust
system inspected by a NISSAN dealer. See the
“Exhaust gas (carbon monoxide) in the “Starting
and driving” section of this manual.
Fluid leaks Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.
Inverter coolant level*Check the coolant level
when the inverter is cold.
Radiator and hoses Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections. Underbody
The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield-washer fluid* Check that there is
adequate fluid in the reservoir.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine and inverter are cold. If the cool-
ant level is below the MIN level
B, add coolant to
the MAX level
A. If the reservoir is empty, check
the coolant level in the radiator when the en-
gine 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 up to the
MAX level
A.
This vehicle contains Genuine NISSAN Long Life
Antifreeze/Coolant (blue) . The life expectancy of
the factory-fill coolant is 105,000 miles (168,000 km) or 7 years. Mixing any other type of coolant or
the use of non-distilled water will reduce the life
expectancy of the factory-fill coolant. Refer to the
NISSAN Service and Maintenance Guide for
more details.
If the cooling system frequently requires
coolant, have it checked by a NISSAN
dealer.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine coolant.
The service procedure can be found in the
NISSAN 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 en-
gine 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 the reach of chil-
dren 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/Coolant (blue) and
50% water to provide year-round anti-freeze and
coolant protection. The anti-freeze solution con-
tains rust and corrosion inhibitors. Additional in-
verter cooling system additives are not neces-
sary.
WARNING
●The temperature of the inverter rises to
140° F (60° C) . Never remove the coolant
reservoir cap when the engine and in-
verter are hot. Wait until the engine and
inverter cool down. Serious burns could
be caused by high pressure fluid escap-
ing from the reservoir.
● The inverter reservoir is equipped with a
pressure type cap. To prevent engine
and inverter damage, use only a genu-
ine NISSAN inverter reservoir cap.
CAUTION
When adding or replacing coolant, be sure
to use only a Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent.
Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted to
provide antifreeze protection to -34° F
(-37° C) . If additional antifreeze protection
is needed due to weather where you oper-
ate your vehicle, add Genuine NISSAN
Long Life Antifreeze/Coolant (blue) . The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent,
may damage the inverter cooling system.
CHECKING INVERTER COOLANT
LEVEL
Check the coolant level in the reservoir when
the engine and inverter are cold. If the cool-
ant level is below the MIN level

WINDSHIELD-WASHER FLUID
RESERVOIR
Fill the windshield-washer fluid reservoir periodi-
cally. Add windshield-washer fluid when the low
windshield-washer fluid warning light comes on.
To fill the windshield-washer fluid reservoir, lift
the cap off the reservoir and pour the windshield-
washer fluid into the reservoir opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a windshield
washer antifreeze. Follow the manufacturer’s in-
structions for the mixture ratio.Refill the reservoir more frequently when driving
conditions require an increased amount of
windshield-washer fluid.
Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Anti-
freeze or equivalent.
CAUTION
●
Do not substitute engine anti-freeze
coolant for windshield-washer fluid.
This may result in damage to the paint.
● Do not fill the windshield-washer fluid
reservoir with washer fluid concen-
trates at full strength. Some methyl al-
cohol based washer fluid concentrates
may permanently stain the grille if
spilled while filling the windshield-
washer fluid reservoir.
● Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the windshield-washer fluid reser-
voir. Do not use the windshield-washer
fluid reservoir to mix the washer fluid
concentrate and water. The 12-volt battery is located on the right hand
side of the trunk behind an access panel.
● Keep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
● Make certain the terminal connections are
clean and securely tightened.
● If the vehicle is not to be used for 30 days or
longer, disconnect the negative (-) battery
terminal cable to prevent discharge.
