warning light NISSAN ALTIMA SL 2019 Owner's Manual

WARNING
Steering Assist is not a system for
hands-free driving. Always keep your
hands on the steering wheel and drive
your vehicle safely. Failure to do so
could cause a collision resulting in seri-
ous personal injury or death.
NOTE:
If the driver lightly touches (instead of
firmly grips) the steering wheel, the
steering torque sensor may not detect
the driver’s hand(s) on the wheel and a
sequence of warnings may occur. When
the driver holds and operates the steer-
ing wheel again, the warnings turn off.
Steering Assist limitations

∙ Once the automatic brake controloperates, it does not operate again if
the vehicle approaches the same
obstacle.
∙ The automatic brake control can only operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
∙ In the following situations, the RAB system may not operate properly or
may not function sufficiently:
– The vehicle is driven in bad weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep hill.
– The vehicle’s posture is changed (e.g., when driving over a bump).
– The vehicle is driven on a slippery road.
– The vehicle is turned sharply by turning the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than NISSAN recommended are used. – The brakes are cold at low ambient
temperatures or immediately af ter
driving has started.
– The braking force becomes poor due to wet brakes af ter driving
through a puddle or washing the
vehicle.
∙ Turn the RAB system off in the follow- ing conditions to prevent the occur-
rence of an unexpected accident
resulting from sudden system
operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed truck.
– The vehicle is on the chassis dynamometer.
– The vehicle drives on an uneven road surface.
– Suspension parts other than those designated as Genuine NISSAN
parts are used. (If the vehicle
height or the vehicle body inclina-
tion is changed, the system may
not detect an obstacle correctly.) ∙ Excessive noise (e.g., audio system
volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “Sys-
tem fault” warning message will appear in
the vehicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.
Starting and driving5-129

– Driving on a steep downhill slopeor roads with sharp curves.
– Driving on a bumpy road surface, such as an uneven dirt road.
– If dirt, ice, snow or other material is covering the radar sensor area.
– Interference by other radar sources.
– The camera area of the windshield is fogged up, or covered with dirt,
water drops, ice, snow, etc.
– Strong light (for example, sunlight or high beams from oncoming ve-
hicles) enters the front camera.
Strong light causes the area
around the pedestrian to be cast in
a shadow, making it difficult to see.
– A sudden change in brightness oc- curs. (For example, when the ve-
hicle enters or exits a tunnel or a
shaded area or lightning flashes.)
– The poor contrast of a person to the background, such as having
clothing color or pattern which is
similar to the background. – The pedestrian’s profile is partially
obscured or unidentifiable due to
the pedestrian transporting lug-
gage, wearing bulky or very loose-
fitting clothing or accessories.
∙ The system performance may de- grade in the following conditions:
– The vehicle is driven on a slippery road.
– The vehicle is driven on a slope.
– Excessively heavy baggage is loaded in the rear seat or the trunk
room of your vehicle.
∙ The system is designed to automati- cally check the sensor’s (radar and
camera) functionality, within certain
limitations. The system may not de-
tect blockage of sensor areas covered
by ice, snow or stickers, for example.
In these cases, the system may not be
able to warn the driver properly. Be
sure that you check, clean and clear
sensor areas regularly. ∙ In some road and traffic conditions,
the AEB with Pedestrian Detection
system may unexpectedly apply par-
tial braking. When acceleration is nec-
essary, depress the accelerator pedal
to override the system.
∙ Excessive noise will interfere with the warning chime sound, and the chime
may not be heard.
5-144Starting and driving

light will illuminate. In a safe location, stop
the engine and place the ignition switch in
the OFF position. The temperature of the
power steering system will go down af ter a
period of time and the power assist level
will return to normal af ter starting the en-
gine. The power steering warning light will
go off. Avoid repeating such steering wheel
operations that could cause the power
steering system to overheat.
You may hear a noise from the front of the
vehicle when the steering wheel is oper-
ated. This is a normal operational noise
and is not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the power steering system is not
functioning properly and may need servic-
ing. Have the power steering system
checked. It is recommended that you visit a
NISSAN dealer for this service.
When the power steering warning light illu-
minates with the engine running, the
power assist for the steering will cease op-
eration but you will still have control of the
vehicle. At this time, greater steering efforts
are required to operate the steering wheel,
especially in sharp turns and at low speeds.The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and stopping distance will
be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshif t to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.

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 above3-6mph(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.

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.

∙ 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 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.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below:
Stopping the vehicle
1. Safely move the vehicle off the road and
away 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 assis-
tance personnel that you need assis-
tance.
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
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 (
A,B,C,D).

∙ If your vehicle was originallyequipped with four tires that were the
same size and you are only replacing
two of the four tires, install the new
tires on the rear axle. Placing new tires
on the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and per-
sonal injury.
∙ If the wheels are changed for any rea- son, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information
on wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical
and consumer information” section of
this manual. ∙ 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 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 this service.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
∙ The TPMS sensor may be damaged if it is not handled correctly. Be careful
when handling the TPMS sensor.
∙ When replacing the TPMS sensor, the ID registration may be required. It is
recommended that you visit a NISSAN
dealer for ID registration.
∙ Do not use a valve stem cap that is not specified by NISSAN. The valve stem
cap may become stuck.
∙
Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and cause
a malfunction or loss of pressure.
∙ Do not install a damaged or deformed wheel or tire even if it has been re-
paired. Such wheels or tires could
have structural damage and could fail
without warning.
∙ The use of retread tires is not recommended.
∙ For additional information regarding tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
∙ For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Do-it-yourself8-41

WARNING
A vehicle equipped with All -Wheel Drive
(AWD) should never be tested using a
two wheel dynamometer (such as the
dynamometers used by some states for
emissions testing), or similar equip-
ment. Make sure you inform the test fa-
cility 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 ve-
hicle damage or personal injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle
may be required to be in what is called
the “ready condition” for an Inspection/
Maintenance (I/M) test of the emission
control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the ready condition can
be obtained by ordinary usage of the ve-
hicle. If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready” condi-
tion. Before taking the I/M test, check the
vehicle’s inspection/maintenance test
readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds , the I/M test
condition is “not ready”. If the MIL does not
blink af ter 20 seconds, the I/M test condi-
tion is “ready”. It is recommended that you
visit a NISSAN dealer to set the “ready con-
dition” or to prepare the vehicle for testing.
This vehicle is equipped with an EDR. The
main purpose of an EDR is to record, in
certain collision or near collision-like situa-
tions, such as an air bag deployment or
hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems
performed. The EDR is designed to record
data related to vehicle dynamics and
safety systems for a short period of time,
typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
∙ How various systems in your vehicle were operating;
∙ Whether or not the driver and passen- ger safety belts were buckled/fastened;
∙ How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
∙ How fast the vehicle was traveling.
∙ Sounds are not recorded.
