engine NISSAN MAXIMA 2021 Owner´s Manual

•If engine control related parts are not
NISSAN recommended or are ex-
tremely deteriorated, the
indi-
cator light may illuminate.
• When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the
indicator
light may flash. Do not drive on these
types of roads.
• When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator light may
flash. This is not a malfunction. Re-
start the engine af ter driving onto a
stable surface.
• If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not oper-
ate properly and the
indicator
light may flash.
• The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road. The Integrated Dynamics-control Module
is an electric control module that includes
the following functions:
• Intelligent Trace Control
• Intelligent Engine Brake
• Active Ride Control
INTELLIGENT TRACE CONTROL
(I-TC)
This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels to aid tracing at corners
and help smooth vehicle response.
The I–TC can be set to ON (enabled) or OFF
(disabled) through the vehicle information
display “Settings” page. For additional infor-
mation, see “Vehicle information display”
(P. 2-17).
When the VDC OFF switch is used to turn off
the VDC system, the I–TC is also turned off.
If the Chassis Control System Error warn-
ing message appears in the vehicle infor-
mation display, it may indicate that the I–TC
is not functioning properly. Have the sys-
tem checked as soon as possible. It is rec-
ommended that you visit a NISSAN dealer
for this service.
WARNING
The I–TC may not be effective depend-
ing on the driving condition. Always
drive carefully and attentively.
When the I–TC is operating, you may feel a
pulsation in the brake pedal and hear a
noise. This is normal and indicates that the
I–TC is operating properly.
Even if the I–TC is set to OFF, some func-
tions will remain on to assist the driver (for
example, avoidance scenes).
INTELLIGENT ENGINE BRAKE (I-EB)
The I–EB function adds subtle deceleration
by controlling the Continuously Variable
Transmission (CVT) gear ratio, depending
on the cornering condition calculated from
the driver's steering input and plural sen-
sors. This benefit is for easier traceability
and less workload of adjusting speed with
braking at corners.
The I–EB also enhances braking feel by
adding subtle deceleration with the CVT
gear ratio control according to the driver's
brake pedal operation.

The I–EB can be set to ON (enabled) or OFF
(disabled) through the vehicle information
display “Settings” page. For additional infor-
mation, see “Vehicle information display”
(P. 2-17).
If the Chassis Control System Error warn-
ing message appears in the vehicle infor-
mation display, it may indicate that the I–EB
is not functioning properly. Have the sys-
tem checked as soon as possible. It is rec-
ommended that you visit a NISSAN dealer
for this service.
WARNING
The I–EB may not be effective depend-
ing on driving conditions. Always drive
carefully and attentively.
When the I–EB is operating, the needle of
the tachometer will rise up and you may
hear an engine noise. This is normal and
indicates that the I–EB is operating
properly.
ACTIVE RIDE CONTROL (ARC)
This system senses upper body motion
(based on wheel speed information) and
controls engine torque and four wheel
brake pressure. This will enhance ride com-
fort in effort to restrain uncomfortable up- per body movement when passing over
undulated road surfaces. This system
comes into effect above 25 mph (40 km/h).
When the VDC OFF switch is used to turn off
the VDC system, the ARC is also turned off.
If the Chassis Control System Error warn-
ing message appears in the vehicle infor-
mation display, it may indicate that the ARC
is not functioning properly. Have the sys-
tem checked as soon as possible. It is rec-
ommended that you visit a NISSAN dealer
for this service.
When the ARC is operating, you may hear
noise and sense slight deceleration. This is
normal and indicates that the ARC is oper-
ating properly.
The sonar (parking sensor) system sounds
a tone to inform the driver of obstacles
near the bumper.
When the “DISPLAY” key is ON, the sonar
view will automatically appear in the meter.
WARNING
• The sonar (parking sensor) system is
a convenience but it is not a substi-
tute for proper parking.
•
The driver is always responsible for
safety during parking and other ma-
neuvers. Always look around and check
that it is safe to do so before parking.

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
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P. 8-13).
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. • A sturdy, flat board to be placed under the
jack 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.
COLD WEATHER DRIVING
5-120Starting and driving

•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.
• Do not change or modif y speakers in- cluding the woofer and any audio re-
lated components such as the
amplifier.
• Do not make any modification includ- ing sound deadening or modifications
around the microphones, speakers, or
woofer.
ACTIVE SOUND CONTROL
Active sound control enhances existing en-
gine sounds according to the engine
speed and driving modes through the
speakers and woofer.

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.

Jacking up vehicle and removing
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 bat-
tery, always wear suitable eye pro-
tectors (for example, goggles or in-
dustrial 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.
