2020 NISSAN ALTIMA ESP

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.
CHASSIS CONTROL HILL START ASSIST SYSTEM
5-174Starting and driving

When the vehicle is stopped on a hill, the hill
start assist system automatically keeps
the brakes applied to help prevent the ve-
hicle from rolling backward in the time it
takes the driver to release the brake pedal
and apply the accelerator.
The hill start assist system will operate au-
tomatically under the following conditions:∙ The transmission is shif ted to a forward or reverse gear.
∙ The vehicle is stopped completely on a hill by applying the brake. The maxi-
mum holding time is 2 seconds. Af ter
2 seconds the vehicle will begin to roll
back and the hill start assist system will
stop operating completely.
The hill start assist system will not operate
when the shif t lever is placed in the N (Neu-
tral) or P (Park) position or on a flat and level
road. The RSS 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
touch-screen display. An additional view of
the sonar status will appear in the vehicle
information display for reference.WARNING
∙ The RSS is a convenience but it is not a
substitute 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.
∙ Read and understand the limitations of the RSS as contained in this section.
The colors of the corner sonar indica-
tor and the distance guide lines in the
rear view indicate different distances
to the object.
∙ Inclement weather or ultrasonic sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may affect
the function of the system; this may
include reduced performance or a
false activation.
∙ This function is designed as an aid to the driver in detecting large station-
ary objects to help avoid damaging
the vehicle.

Jacking up vehicle and removing
the damaged tire
WARNING
∙ Never get under the vehicle while it issupported only by the jack. If it is nec-
essary to work under the vehicle, sup-
port 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 designed
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.

CAUTION
When cleaning the inside of the win-
dows, do not use sharp-edged tools,
abrasive cleaners or chlorine-based
disinfectant cleaners. They could dam-
age the electrical conductors, radio an-
tenna elements or rear window defog-
ger elements.
ALUMINUM ALLOY WHEELS (if so
equipped)
Wash the wheels regularly with a sponge
dampened in a mild soap solution, espe-
cially during winter months in areas where
road salt is used. If not removed, road salt
can discolor the wheels.
CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
∙ Do not use a cleaner that uses strongacid or alkali contents to clean the
wheels.
∙ Do not apply wheel cleaners to the wheels when they are hot. The wheel
temperature should be the same as
ambient temperature.
∙ Rinse the wheel to completely remove the cleaner within 15 minutes af ter
the cleaner is applied.
CHROME PARTS
Clean all chrome parts regularly with a
non-abrasive chrome polish to maintain
the finish.
TIRE DRESSINGS
NISSAN does not recommend the use of
tire dressings. Tire manufacturers apply a
coating to the tires to help reduce discolor-
ation of the rubber. If a tire dressing is ap-
plied to the tires, it may react with the coat-
ing and form a compound. This compound
may come off the tire while driving and
stain the vehicle paint.
If you choose to use a tire dressing, take the
following precautions:
∙ Use a water-based tire dressing. The coating on the tire dissolves more easily
than with an oil-based tire dressing.
∙ Apply a light coat of tire dressing to help prevent it from entering the tire
tread/grooves (where it would be diffi-
cult to remove).
∙ Wipe off excess tire dressing using a dry towel. Make sure the tire dressing is
completely removed from the tire
tread/grooves.
∙ Allow the tire dressing to dry as recom- mended by the tire dressing manufac-
turer.

MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
Most vehicle corrosion is caused by:∙ The accumulation of moisture- retaining dirt and debris in body panel
sections, cavities, and other areas.
∙ Damage to paint and other protective coatings caused by gravel and stone
chips or minor traffic collisions.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on
the vehicle body underside can accelerate
corrosion. Wet floor coverings will not dry
completely inside the vehicle and should
be removed for drying to avoid floor panel
corrosion.
Relative humidity
Corrosion will be accelerated in areas of
high relative humidity, especially those ar-
eas where the temperatures stay above freezing and where atmospheric pollution
exists and road salt is used.
Temperature
High temperatures accelerate the rate of
corrosion to those parts which are not well
ventilated.
Air pollution
Industrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use accelerates the corrosion process.
Road salt also accelerates the disintegra-
tion of paint surfaces.
PROTECT YOUR VEHICLE FROM
CORROSION
∙ Wash and wax your vehicle of ten to
keep the vehicle clean.
∙ Always check for minor damage to the paint and repair it as soon as possible.
∙ Keep drain holes at the bottom of the doors open to avoid water accumula-
tion.
∙ Check the underbody for accumulation of sand, dirt or salt. If present, wash with
water as soon as possible.
CAUTION
∙ NEVER remove dirt, sand or other de-bris from the passenger compart-
ment by washing it out with a hose.
Remove dirt with a vacuum cleaner or
broom.
∙ Never allow water or other liquids to come in contact with electronic com-
ponents inside the vehicle as this may
damage them.
Chemicals used for road surface de-icing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor pan
and fenders.
In winter, the underbody must be
cleaned periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, it is recommended that you visit a
NISSAN dealer.

outlined in this section.
Replacing the halogen headlight
bulb (if so equipped)
The headlight is a semi-sealed beam type
which uses a replaceable headlight (halo-
gen) bulb. They can be replaced from inside
the engine compartment without remov-
ing the headlight assembly.
If headlight bulb replacement is required, it
is recommended that you visit a NISSAN
dealer for this service.
CAUTION
∙ Aiming is not necessary af ter replac-ing the bulb. When aiming adjustment
is necessary, it is recommended that
you visit a NISSAN dealer for this
service. ∙ Do not leave the headlight assembly
open without a bulb installed for a

Some day-to-day and regular mainte-
nance is essential to maintain your vehicle
good mechanical condition, as well as its
emissions and engine performance.
It is the owner’s responsibility to make sure
that the scheduled maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
proper maintenance. You are a vital link in
the maintenance chain.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal
day-to-day operation. They are essential
for proper vehicle operation. It is your re-
sponsibility to perform these procedures
regularly as prescribed.
Performing general maintenance checks
requires minimal mechanical skill and only
a few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, a NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this sec-
tion are required to be serviced at regular
intervals. However under severe driving
conditions, additional or more frequent
maintenance will be required.

9-2Maintenance and schedules

To help ensure smooth, safe and economi-
cal driving, NISSAN provides two mainte-
nance schedules that may be used, de-
pending upon the conditions in which you
usually drive. These schedules contain
both distance and time intervals, up to
120,000 miles (192,000 km)/144 months. For
most people, the odometer reading will in-
dicate when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals
shown in the schedule.
Af ter 120,000 miles (192,000 km)/
144 months, continue maintenance at
the same mileage/time intervals.ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditionsshould be per-
formed on vehicles that are driven under
especially demanding conditions. Addi-
tional maintenance items should be per-
formed if you primarily operate your vehicle
under the following conditions:
∙ Repeated short trips of less than 5 miles (8 km).
∙ Repeated short trips of less than 10 miles (16 km) with outside tempera-
tures remaining below freezing.
∙ Operating in hot weather in stop- and-go “rush hour” traffic.
∙ Extensive idling and/or low speed driv- ing for long distances, such as police,
taxi or door-to-door delivery use.
∙ Driving in dusty conditions.
∙ Driving on rough, muddy or salt spread roads.
∙ Using a car-top carrier.
OIL CONTROL SYSTEM
Your vehicle is equipped with oil control
system. It calculates engine oil and filter
change intervals based on driving condi-
tions. Driving in the following severe condi-
tions will shorten the engine oil and filter
change interval.
