2021 NISSAN MAXIMA heater

CAUTION
• Continuously Variable Transmission
(CVT) models cannot be push-
started or tow-started. Attempting
to do so may cause transmission
damage.
• Do not push start this vehicle. The
three-way catalyst may be
damaged. 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.
WARNING
• Do not continue to drive if your ve-
hicle 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 radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
• Do not open the hood if steam is
coming out.
1. Move the vehicle safely off the road, ap- ply the parking brake and move the shif t
lever to P (Park).
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. (If
steam or coolant is escaping, turn off
the engine.) Do not open the hood fur-
ther until no steam or coolant can be
seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water. If coolant is
leaking, the water pump belt is missing
or loose, 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 con-
tact with, or get caught in, engine belts
or the engine cooling fan. The engine
cooling fan can start at any time.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
OB, add coolant
to the MAX level
OA. If the reservoir is empty,
check the coolant level in the radiator
when the engine is cold. If there is insuffi-
cient 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
OA. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy 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 ex-
pectancy of the factory-fill coolant. For ad-
ditional information, see the “Maintenance
and schedules” section of this manual.
If the cooling system frequently requires
coolant, it is recommended that you visit
a NISSAN dealer for this service.
For additional information on the location
of the engine coolant reservoir, see “Engine
compartment check locations” (P. 8-3).
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
overheating.
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 es-
caping 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 prop-
erly. Check your local regulations.

Brakes:Check that the brakes do not pull
the vehicle to one side when applied.
Continuously Variable Transmission
(CVT) P (Park) position mechanism: On a
fairly steep hill check that the vehicle is held
securely with the shif t lever in the P (Park)
position without applying any brakes.
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 adjustment, it is recom-
mended that you visit a NISSAN dealer for
this service.
Seats: Check seat position controls such
as seat adjusters, seatback recliner, etc., to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage. Steering wheel:
Check for changes in the
steering system, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure 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.
Windshield wiper and washer*: Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
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).
Battery* (for maintenance free batter-
ies): This vehicle is equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not run-
ning (Phone chargers, GPS, DVD
players, etc.).
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
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 the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
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.
