engine NISSAN MAXIMA 2023 Owners Manual

The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the sonar sensors.
Check for and remove objects obstructing
the area around the sonar sensors.
Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the sonar sensors is damaged due to a
collision.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry function on the Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
see “Engine cooling system” (P. 8-4).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For ad-
ditional information, see “Battery” (P. 8-14).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, see
“Changing engine coolant” (P. 8-5).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re- move ice and snow from the windows
and wiper blades.
COLD WEATHER DRIVING
5-124Starting and driving

• A sturdy, flat board to be placed under thejack to give it firm support.
• A shovel to dig the vehicle out of snowdrif ts.
• Extra washer fluid to refill the windshield- washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
• Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” un-
der these conditions. Try to avoid
driving on wet ice until the road is
salted or sanded.
• Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shif ting too fast, the drive wheels will
lose even more traction.
•
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
• Allow greater following distances on
slippery roads. •
Watch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steer-
ing maneuvers.
• Do not use the cruise control on slip-
pery roads.
• Snow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ACTIVE NOISE CANCELLATION
This system uses three microphonesO1
located inside the vehicle to detect engine
booming noises. The system then auto-
matically generates a noise canceling
sound through the speakers and woofer to
reduce engine booming noise.
NOTE:
To operate the active noise cancella-
tion system properly:
• Do not cover the speakers or woofer.
• Do not cover the microphones.

below:
Stopping the vehicle
1. Safely move the vehicle off the road andaway from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shif t lever to P
(Park).
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the ve- hicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
•
Make sure the parking brake is se-
curely applied and the Continuously
Variable Transmission (CVT) is shif ted
into P (Park).
• Never change tires when the vehicle
is on a slope, ice or slippery areas.
This is hazardous.
• Never change tires if oncoming traf-
fic is close to your vehicle. Wait for
professional road assistance.
Blocking wheels
Place suitable blocks at both the front and
back of the wheel diagonally opposite the
flat tire to prevent the vehicle from moving
when it is jacked up.
WARNING
Be sure to block the wheel as the ve-
hicle may move and result in personal
injury.

the damaged tire
WARNING
• Never get under the vehicle while it is
supported only by the jack. If it is nec-
essary to work under the vehicle,
support it with safety stands. •
Use only the jack provided with your
vehicle to lif t the vehicle. Do not use
the jack provided with your vehicle
on other vehicles. The jack is de-
signed for lif ting only your vehicle
during a tire change.
• Use the correct jack-up points. Never
use any other part of the vehicle for
jack support.
• Never jack up the vehicle more than
necessary.
• Never use blocks on or under the
jack.
• Do not start or run the engine while
vehicle is on the jack. It may cause
the vehicle to move. This is especially
true for vehicles with limited slip
differentials.
• Do not allow passengers to stay in
the vehicle while it is on the jack.
• Never run the engine with a wheel(s)
off the ground. It may cause the ve-
hicle to move.

6-6In case of emergency

To start your engine with a booster battery,
the instructions and precautions below
must be followed.
WARNING
• If done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
• Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away
from the battery.
• Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulfuric acid solution which
can cause severe burns. If the fluid
should come into contact with any-
thing, immediately flush the con-
tacted area with water.
• Keep battery out of the reach of
children.
• The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle. •
Whenever working on or near a
battery, always wear suitable eye
protectors (for example, goggles or
industrial safety spectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
battery when jump starting.
• Do not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
• Your vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
JUMP STARTING

WARNING
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.
1. If the booster battery is in another ve- hicle, position the two vehicles to bring
their batteries near each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. Move the shif t lever to P (Park). Switch off all unneces-
sary electrical systems (lights, heater, air
conditioner, etc.). 3. Place the ignition switch in the LOCK
position.
4. Connect the jumper cables in the se- quence illustrated (
OA,OB,OC,OD).
CAUTION
• Always connect positive (+) to posi-
tive (+) and negative (−) to body
ground (for example, strut mounting
bolt, engine lif t bracket, etc.) — not to
the battery. •
Make sure the jumper cables do not
touch moving parts in the engine
compartment and that the cable
clamps do not contact any other
metal.
5. Start the engine of the booster vehicle and let it run for a few minutes.
6. Keep the engine speed of the booster vehicle at about 2,000 rpm and start
the engine of the vehicle being jump
started.
CAUTION
Do not keep the starter motor engaged
for more than 10 seconds. If the engine
does not start right away, place the ig-
nition switch in the OFF position and
wait 3 to 4 seconds before trying again.
7. Af ter starting the engine, carefully dis- connect the negative cable and then the
positive cable.LCE2223
6-10In case of emergency

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 or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant res-
ervoir 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
radiator 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.
