2020 NISSAN ALTIMA engine

– An ultrasonic wave source, such asanother vehicle’s sonar, is near the
vehicle.
∙ Once the automatic brake control op- erates, 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 re-
sulting 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.

SYSTEM TEMPORARILY
UNAVAILABLE
Condition A
When the radar sensor picks up interfer-
ence from another radar source, making it
impossible to detect a vehicle ahead, the
AEB system is automatically turned off.
The AEB system warning light (orange) will
illuminate.
Action to take:
When the above conditions no longer exist,
the AEB system will resume automatically.
Condition B
When the radar sensor of the front bumper
is covered with dirt or is obstructed, the
AEB system will automatically be canceled.
The chime will sound and the “Not Avail-
able: Front Radar Blocked” warning mes-
sage will appear in the vehicle information
display.
Action to take:
If the warning message appears, stop the
vehicle in a safe place, place the shif t lever
in the P (Park) position, and turn the engine
off. When the radar signal is temporarily
interrupted, clean the sensor area of the

front bumper and restart the engine. If the
“Not Available: Front Radar Blocked” warn-
ing message continues to be displayed,
have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
Condition C
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snowfields, driving next to
long walls), the system may illuminate the
system warning light and display the “Not
Available: Front Radar Blocked” message.
Action to take:
When the above driving conditions no lon-
ger exist, turn the system back on.
NOTE:
If the AEB system stops working, the
I-FCW system will also stop working.
SYSTEM MALFUNCTION
If the AEB system malfunctions, it will be
turned off automatically, a chime will
sound, the AEB warning light (orange) will
illuminate and the warning message [Mal-
function] will appear in the vehicle informa-
tion display.Action to take
If the warning light (orange) comes on, stop
the vehicle in a safe location, turn the en-
gine off and restart the engine. If the warn-
ing light continues to illuminate, have the
AEB system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
SYSTEM MAINTENANCE
The sensor1for the AEB is located on the
front of the vehicle.
To keep the system operating properly, be
sure to observe the following:
∙ Always keep the sensor area of the front bumper clean.
∙ Do not strike or damage the areas around the sensor.
∙ Do not cover or attach stickers or simi- lar objects on the front bumper near
the sensor area. This could cause failure
or malfunction.
