2020 NISSAN ALTIMA four wheel drive

∙ When replacing a wheel without theTPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN dealer
for these services.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
CAUTION
∙ The TPMS is not a substitute for theregular tire pressure check. Be sure to
check the tire pressure regularly.
∙ If the vehicle is being driven at speeds of less than 16 mph (25 km/h), the
TPMS may not operate correctly.
∙ Be sure to install the specified size of tires to the four wheels correctly.
Master warning light
When the ignition is in the ON position, the
master warning light illuminates if any of
the following are displayed on the vehicle
information display.
∙ No key warning
∙ Low windshield-washer fluid warning
∙ Parking brake release warning
∙ Door/trunk open warning
∙ Loose fuel cap
∙ Low tire pressure warning
Power steering warninglight
WARNING
∙ If the engine is not running or is turned off while driving, the power as-
sist for the steering will not work.
Steering will be harder to operate. ∙ When the power steering warning
light illuminates with the engine run-
ning, there will be no power assist for
the steering. You will still have control
of the vehicle, but the steering will be
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
When the ignition switch is placed in the ON
position, the power steering warning light
illuminates. Af ter starting the engine, the
power steering warning light turns off. This
indicates the power steering is operational.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the power steering is not function-
ing properly and may need servicing. Have
the power steering checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
When the power steering warning light illu-
minates with the engine running, there will
be no power assist for the steering, 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.

WARNING
Failure to follow the warnings and in-
structions for the proper use of the In-
telligent Around View Monitor system
could result in serious injury or death
∙ The Intelligent Around View Monitor isa convenience feature and is not a
substitute for proper vehicle opera-
tion because it has areas where ob-
jects cannot be viewed. The four cor-
ners of the vehicle in particular, are
areas where objects do not always
appear in the bird’s-eye, front, or rear
views. Always check your surround-
ings to be sure that it is safe to move
before operating the vehicle. Always
operate the vehicle slowly.
∙ The driver is always responsible for safety during parking and other
maneuvers.
CAUTION
Do not scratch the camera lens when
cleaning dirt or snow from the front of
the camera. The Intelligent Around View Monitor sys-
tem is designed as an aid to the driver in
situations such as slot parking or parallel
parking.
The monitor displays various views of the
position of the vehicle in a split screen for-
mat. Not all views are available at all times.
Available views:
∙ Front View An approximately 150–degree view of
the front of the vehicle.
∙ Rear View An approximately 150–degree view of
the rear of the vehicle.
∙ Bird’s-Eye View The surrounding views of the vehicle
from above.
∙ Front-Side View The view around and ahead of the front
passenger’s side wheel.
∙ Full Screen Rear View The view to the rear of the vehicle
(which is a little wider than the standard
Rear View). To display the multiple views, the Intelligent
Around View Monitor system uses cam-
eras located in the front grille, on the vehi-
cle’s outside mirrors and one just above
the vehicle’s license plate

Additional information:∙ When replacing a wheel without the TPMS such as the spare tire, the TPMS
does not monitor the tire pressure of
the spare tire.
∙ The TPMS will activate only when the vehicle is driven at speeds above
16 mph (25 km/h). Also, this system may
not detect a sudden drop in tire pres-
sure (for example, a flat tire while driv-
ing).
∙ The low tire pressure warning light does not automatically turn off when the tire
pressure is adjusted on all four tires. Af-
ter all four tires are inflated to the rec-
ommended pressure, the vehicle must
be driven at speeds above 16 mph
(25 km/h) to activate the TPMS and turn
off the low tire pressure warning light.
Use a tire pressure gauge to check the
tire pressure.
∙ The “Tire Pressure Low - Add Air” warn- ing appears in the vehicle information
display when the low tire pressure
warning light is illuminated and low tire
pressure is detected. The “Tire Pressure
Low - Add Air” warning turns off when
the low tire pressure warning light turns
off. ∙ The “Tire Pressure Low - Add Air” warn-
ing appears each time the ignition
switch is placed in the ON position as
long as the low tire pressure warning
light remains illuminated.
∙ The “Tire Pressure Low - Add Air” warn- ing does not appear if the low tire pres-
sure warning light illuminates to indi-
cate a TPMS malfunction.
∙ Tire pressure rises and falls depending on the heat caused by the vehicle’s op-
eration and the outside temperature.
Do not reduce the tire pressure af ter
driving because the tire pressure rises
af ter driving. Low outside temperature
can lower the temperature of the air
inside the tire which can cause a lower
tire inflation pressure. This may cause
the low tire pressure warning light to
illuminate. If the warning light illumi-
nates, check the tire pressure for all four
tires.
∙ The Tire and Loading Information label is located in the driver’s door opening. ∙ You can also check the tire pressure of
all tires (except the spare) on the vehicle
information display screen. The order of
the tire pressure figures displayed on
the screen corresponds with the actual
order of the tire position.
For additional information, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section, “Tire Pressure Moni-
toring System (TPMS)” in the “In case of
emergency” section and “Tire pressure” in
the “Do-it-yourself ” section of this manual.
WARNING
∙ Radio waves could adversely affect electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
5-6Starting and driving

∙ Failure to operate this vehicle cor-rectly could result in loss of control
and/or a rollover accident.
∙ Always use tires of the same type, size, brand, construction (bias, bias-
belted, or radial), and tread pattern on
all four wheels. Install tire chains on
the front wheels when driving on slip-
pery roads and drive carefully.
∙ Be sure to check the brakes immedi- ately af ter driving in mud or water. For
additional information, refer to “Brake
precautions” in this section.
∙ Avoid parking your vehicle on steep hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured.
∙ Whenever you drive off-road through sand, mud or water as deep as the
wheel hub, more frequent mainte-
nance may be required. For additional
information, refer to “Maintenance
under severe operating conditions” in
the “Maintenance and schedules” sec-
tion of this manual.WARNING
Do not operate the push-button igni-
tion switch while driving the vehicle ex-
cept in an emergency. (The engine will
stop when the ignition switch is pushed
three consecutive times in quick suc-
cession or the ignition switch is pushed
and held for more than 2 seconds.) If the
engine stops while the vehicle is being
driven, this could lead to a crash and
serious injury.
When the ignition switch is pushed without
depressing the brake pedal, the ignition
switch will illuminate.
Push the ignition switch center:∙ Once to change to ON.
∙ Two times to change to OFF.
The ignition switch will automatically re-
turn to the LOCK position when any door is
either opened or closed with the switch in
the OFF position.

Starting and driving5-13

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the speed
to maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway,
the ICC system will accelerate and main-
tain the speed up to the set speed. Pay
attention to the driving operation to main-
tain control of the vehicle as it accelerates
to the set speed.
The vehicle may not maintain the set
speed on winding or hilly roads. If this oc-
curs, you will have to manually control the
vehicle speed.Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is re-
quired for a lane change. Depress the brake
pedal when deceleration is required to
maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when us-
ing the ICC system.VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE SWITCHES
The system is operated by the ICC switch
and four control switches, all mounted on
the steering wheel.
1. CANCEL switch:
Deactivates the system without eras-
ing the set speed.
2. RES+ switch:
Resumes set speed or increases
speed incrementally.

WARNING
∙ Do not drive beyond the performancecapability of the tires. Accelerating
quickly, sharp steering maneuvers or
sudden braking may cause loss of
control, even with AWD engaged.
∙ For AWD equipped vehicles, do not at- tempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious personal injury or vehicle
damage.
∙
Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions
testing) or similar equipment even if
the other two wheels are raised off the
ground. Make sure that you inform the
test facility personnel that your vehicle
is equipped with AWD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious per-
sonal injury or vehicle damage.
CAUTION
∙ Do not operate the engine on a free roller when any of the wheels are
raised.
∙ If you use the free roller, rotate four wheels with the same speed without
raising any wheels.
∙ If an AWD warning message is dis- played while driving there may be a
malfunction in the AWD system. Re-
duce the vehicle speed immediately
and have your vehicle checked. It is
recommended that you visit a NISSAN
dealer as soon as possible.
∙ The powertrain may be damaged if you continue driving when the AWD
temperature or tire size incorrect
messages are displayed
∙ If the AWD high temperature message is displayed while you are driving, pull
off the road in a safe area, and idle the
engine. The driving mode will change
to 2WD to prevent the AWD system
from malfunctioning. If the warning
message turns off, you can drive
again. ∙ If the tire size incorrect message is
displayed while you are driving, pull
off the road in a safe area with the
engine idling. Check that all tire sizes
are the same, that the tire pressure is
correct and that the tires are not ex-
cessively worn.
∙ If a warning message continues to be displayed af ter the above operations,
have your vehicle checked as soon as
possible. It is recommended that you
visit a NISSAN dealer for this service.
5-166Starting and driving

– When replacing tires, install thespecified size of tires on all four
wheels.
– When installing a spare tire, make sure that it is the proper size and
type as specified on the Tire and
Loading Information label. For ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer infor-
mation” section of this manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself ” section of this manual.
The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The Anti-lock Braking System (ABS) in-
cludes electronic sensors, electric pumps,
hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature
that tests the system each time you start
the engine and move the vehicle at a low
speed in forward or reverse. When the self-
test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal.
This is normal and does not indicate a mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates the ABS warning light on the
instrument panel. The brake system then
operates normally but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds abov
e3-6mph(5-
10 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion in the brake pedal and hear a noise
from under the hood or feel a vibration
from the actuator when it is operating. This
is normal and indicates that the ABS is op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.
5-170Starting and driving

The chassis control is an electric control
module that includes the following func-
tions:∙ Intelligent Trace Control
∙ 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, refer to “Vehicle information dis-
play” in the “Instruments and controls” sec-
tion of this manual.
When the VDC system is turned off, the I-TC
is also turned off.
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 turned off, some functions
will remain on to assist the driver (for ex-
ample, avoidance scenes).
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 system is turned off, the ARC
is also turned off.
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.
WARNING
∙ Never rely solely on the hill start assist
system to prevent the vehicle from
moving backward on a hill. Always
drive carefully and attentively. De-
press the brake pedal when the ve-
hicle is stopped on a steep hill. Be es-
pecially careful when stopped on a hill
on frozen or muddy roads. Failure to
prevent the vehicle from rolling back-
wards may result in a loss of control of
the vehicle and possible serious injury
or death.
∙ The hill start assist system is not de- signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Failure to do so may cause
the vehicle to roll backwards and may
result in a collision or serious personal
injury.
∙ The hill start assist system may not prevent the vehicle from rolling back-
wards on a hill under all load or road
conditions. Always be prepared to de-
press the brake pedal to prevent the
vehicle from rolling backwards. Fail-
ure to do so may result in a collision or
serious personal injury.
