2020 NISSAN ALTIMA light

WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.The VDC system uses various sensors to
monitor driver inputs and vehicle motion.
Under certain driving conditions, the VDC
system helps to perform the following
functions:
∙ Controls brake pressure to reduce wheel slip on one slipping drive wheel
so power is transferred to a non-
slipping drive wheel on the same axle.
∙ Controls brake pressure and engine output to reduce drive wheel slip based
on vehicle speed (traction control func-
tion).
∙ Controls brake pressure at individual wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
– Understeer (vehicle tends to not fol- low the steered path despite in-
creased steering input)
– Oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to
maintain control of the vehicle, but it can-
not prevent loss of vehicle control in all driv-
ing situations. When the VDC system operates, theindicator light in the instrument panel
flashes to note the following:
∙ The road may be slippery or the system may determine some action is required
to help keep the vehicle on the steered
path.
∙ You may feel a pulsation in the brake pedal and hear a noise or vibration from
under the hood. This is normal and indi-
cates that the VDC system is working
properly.
∙ Adjust your speed and driving to the road conditions.
For additional information, refer to “Slip in-
dicator light” and “Vehicle Dynamic Control
(VDC) OFF indicator light” in the “Instru-
ments and controls” section of this manual.
If a malfunction occurs in the system,
the
indicator light comes on in the
instrument panel. The VDC system auto-
matically turns off when the indicator light
is on.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
Starting and driving5-171

The vehicle information display is used to
turn off the VDC system. When the VDC
system is turned off, the
indicator
light and if so equipped, the RAB system
warning light, AEB system warning light
and AEB with Pedestrian Detection system
warning light illuminate to indicate the
VDC, AEB, AEB with Pedestrian Detection,
and RAB systems are off.
When the VDC system is turned off in the
vehicle information display, the VDC sys-
tem still operates to prevent one drive
wheel from slipping by transferring power
to a non-slipping drive wheel. The
in-
dicator light flashes if this occurs. All other
VDC functions are off and the
indica-
tor light will not flash.
The VDC system is automatically reset to
ON when the ignition switch is placed in the
OFF position then back to the ON position.
The computer has a built-in diagnostic fea-
ture that tests the system each time you
start the engine and move the vehicle for-
ward or in reverse at a slow speed. When
the self-test occurs, you may hear a clunk
noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indica-
tion of a malfunction.
WARNING
∙ The VDC system is designed to help the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed and
be especially careful when driving and
cornering on slippery surfaces and al-
ways drive carefully.
∙ Do not modif y the vehicle’s suspen- sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not NISSAN recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the
indicator light may flash or
the
indicator light may
illuminate. ∙ If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC system
may not operate properly and both
the
andindicator lights
may illuminate.
∙ If engine control related parts are not NISSAN recommended or are ex-
tremely deteriorated, both the
and theindicator lights may
illuminate.
∙ When driving on extremely inclined surfaces such as higher banked cor-
ners, the VDC system may not operate
properly and the
indicator light
may flash or the
indicator light
may illuminate. 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 or the
indicator light may
illuminate. This is not a malfunction.
Restart the engine af ter driving onto
a stable surface.

∙ If wheels or tires other than theNISSAN recommended ones are used,
the VDC system may not operate
properly and the
indicator light
may flash or the
indicator light
may illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow
covered road.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the front and rear wheels
depending on the radius of the turn.
WARNING
∙ The VDC system is designed to helpthe driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed and
be especially careful when driving and

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.

when you must stop or park under emer-
gency conditions. All turn signal lights flash.
WARNING
∙ If stopping for an emergency, be sureto move the vehicle well off the road.
∙ Do not use the hazard warning flash- ers while moving on the highway un-
less unusual circumstances force you
to drive so slowly that your vehicle
might become a hazard to other
traffic.
∙ Turn signals do not work when the hazard warning flasher lights are on.
The flashers will operate with the ignition
switch placed in any position.
Some jurisdictions may prohibit the use
of the hazard warning flasher switch
while driving. To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
– Rapidly push the push-button ignition
switch three consecutive times in less
than 1.5 seconds, or

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pres-
sure Monitoring system (TPMS). It monitors
tire pressure of all tires except the spare.
When the low tire pressure warning light is
lit, and the “Tire Pressure Low - Add Air”
warning appears in the vehicle information
display, one or more of your tires is signifi-
cantly under-inflated. If equipped, the sys-
tem also displays pressure of all tires (ex-
cept the spare tire) on the display screen by
sending a signal from a sensor that is in-
stalled in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will
activate and warn you of it by the low tire
pressure warning light. This system will ac-
tivate only when the vehicle is driven at
speeds above 16 mph (25 km/h). For addi-
tional information, refer to “Warning lights,
indicator lights and audible reminders” in
the “Instruments and controls” section and
“Tire Pressure Monitoring System (TPMS)” in
the “Starting and driving” section of this
manual.
WARNING
∙ Radio waves could adversely affectelectric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
∙ If the low tire pressure warning light illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull off
the road to a safe location and stop
the vehicle as soon as possible. Driv-
ing with under-inflated tires may per-
manently damage the tires and in-
crease the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and could
result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure-
shown on the Tire and Loading Infor-
mation label to turn the low tire pres-
sure warning light OFF. If the light still illuminates while driving af ter adjust-
ing the tire pressure, a tire may be flat
or the TPMS may be malfunctioning. If
you have a flat tire, replace it with a
spare tire as soon as possible. If no tire
is flat and all tires are properly in-
flated, have the vehicle checked. It is
recommended that you visit a NISSAN
dealer for this service.
∙ When replacing a wheel without the TPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately one 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.
∙ Do not inject any tire liquid or aerosol tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.

6-10In case of emergency

In order to maintain the appearance of
your vehicle, it is important to take proper
care of it.
To protect the paint surfaces, wash your
vehicle as soon as you can:∙ Af ter a rainfall to prevent possible dam- age from acid rain.
∙ Af ter driving on coastal roads.
∙ When contaminants such as soot, bird droppings, tree sap, metal particles or
bugs get on the paint surface.
∙ When dust or mud builds up on the sur- face.
Whenever possible, store or park your ve-
hicle inside a garage or in a covered area.
When it is necessary to park outside, park in
a shady area or protect the vehicle with a
body cover.
Be careful not to scratch the paint sur-
face when putting on or removing the
body cover.WASHING
Wash dirt off with a wet sponge and plenty
of water. Clean the vehicle thoroughly us-
ing a mild soap, a special vehicle soap or
general purpose dishwashing liquid mixed
with clean, lukewarm (never hot) water.
CAUTION
∙ Do not concentrate water spray di- rectly on the sonar sensors (if so
equipped) on the bumper as this will
result in damage to the sensors. Do
not use pressure washers capable of
spraying water over 1,200 psi
(8,274 kPa) to wash your vehicle. Use
of high-pressure washers over
1,200 psi (8,274 kPa) can result in dam-
age to or removal of paint or graphics.
Avoid using a high-pressure washer
closer than 12 inches (30 cm) to the
vehicle. Always use a wide-angle
nozzle only, keep the nozzle moving
and do not concentrate the water
spray on any one area. ∙ Do not use car washes that use acid in
the detergent. Some car washes, es-
pecially brushless ones, use some
acid for cleaning. The acid may react
with some plastic vehicle compo-
nents, causing them to crack. This
could affect their appearance, and
also could cause them not to function
properly. Always check with your car
wash to confirm that acid is not used.
∙ Do not wash the vehicle with strong household soap, strong chemical de-
tergents, gasoline or solvents.
∙ Do not wash the vehicle in direct sun- light or while the vehicle body is hot,
as the surface may become
water-spotted.
∙ Avoid using tight-napped or rough cloths, such as washing mitts. Care
must be taken when removing
caked-on dirt or other foreign sub-
stances so the paint surface is not
scratched or damaged.
