2018 NISSAN ALTIMA sensor

To reset at a slower cruising speed,use
one of the following three methods:
∙ Lightly tap the brake pedal. When the vehicle attains the desired speed, push
the COAST/SET switch and release it.
∙ Push and hold the COAST/SET switch. Release the switch when the vehicle
slows to the desired speed.
∙ Push and release the COAST/SET switch. Each time you do this, the set
speed decreases by about 1 mph
(1.6 km/h).
To resume the preset speed, push and
release the ACCEL/RES switch. The vehicle
returns to the last set cruising speed when
the vehicle speed is over 25 mph (40 km/h).
To turn off the cruise control, use one of
the following three methods:
∙ Push the CANCEL switch.
∙ Tap the brake pedal.
∙ Push the ON/OFF switch off. The
light in the instrument panel goes out.
WARNING
Failure to follow the warnings and in-
structions for proper use of the ICC sys-
tem could result in serious injury or
death.
∙ The ICC system is only an aid to assist the driver and is not a collision warn-
ing or avoidance device. It is the driv-
er’s responsibility to stay alert, drive
safely and be in control of the vehicle
at all time.
∙ Always observe posted speed limits and do not set the speed over them.
∙ Always drive carefully and attentively when using the ICC system. Read and
understand the Owner’s Manual thor-
oughly before using the ICC system.
To avoid serious injury or death, do
not rely on the system to prevent ac-
cidents or to control the vehicle’s
speed in emergency situations. Do
not use the ICC system except in ap-
propriate road and traffic conditions. The ICC system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and di-
rection.
The ICC system uses a radar sensor
1
located on the front of the vehicle to detect
vehicles traveling ahead.
If the radar sensor detects a slower moving
vehicle ahead, the system will reduce the
vehicle speed so that your vehicle follows
the vehicle in front at the selected distance.
The detection range of the sensor is ap-
proximately 390 f t (120 m) ahead.

2. Middle 150 (45)
3. Short 90 (30)
∙ The distance to the vehicle ahead will change according to the vehicle speed.
The higher the vehicle speed, the longer
the distance.
∙ If the engine is stopped, the set distance becomes “long.” (Each time the engine
is started, the initial setting becomes
“long.”)
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the sys-
tem warns the driver with the chime and
ICC system display. Decelerate by depress-
ing the brake pedal to maintain a safe ve-
hicle distance if:
∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
The warning chime may not sound in
some cases when there is a short distance
between vehicles. Some examples are: ∙ When the vehicles are traveling at the same speed and the distance between
vehicles is not changing.
∙ When the vehicle ahead is traveling faster and the distance between ve-
hicles is increasing.
∙ When a vehicle cuts in near your vehicle.
The warning chime will not sound when: ∙ The vehicle approaches other vehicles that are parked or moving slowly.
∙ The accelerator pedal is depressed, overriding the system. NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects objects on the
side of the vehicle or on the side of the
road. This may cause the ICC system to
decelerate or accelerate the vehicle. The
ICC sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads, or when
entering or exiting a curve. In these
cases you will have to manually control
the proper distance ahead of your ve-
hicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or ve-
hicle condition (for example, if a vehicle is
being driven with some damage).

∙ The system may not detect the ve-hicle in front of you in certain road or
weather conditions. To avoid acci-
dents, never use the ICC system under
the following conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance
sensor
– On steep downhill roads (the ve- hicle may go beyond the set ve-
hicle speed and frequent braking
may result in overheating the
brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it dif- ficult to keep a proper distance be-
tween vehicles because of fre-
quent acceleration or deceleration – Interference by other radar
sources.
∙ Do not use the ICC system if you are towing a trailer. The system may not
detect a vehicle ahead.
∙ In some road or traffic conditions, a vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The radar sensor will not detect the follow-
ing objects: ∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane
The following are some conditions in which
the sensor cannot properly detect a ve-
hicle ahead and the system may not oper-
ate properly: ∙ When snow or road spray from traveling vehicles reduces the sensor’s detection. ∙ When excessively heavy baggage is
loaded in the rear seat or the trunk of
your vehicle.
The ICC system is designed to automati-
cally check the sensor’s operation within
the limitations of the system.
The detection zone of the ICC sensor is
limited. A vehicle ahead must be in the de-
tection zone for the vehicle-to-vehicle dis-
tance detection mode to maintain the se-
lected distance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within
the same lane of travel. Motorcycles may
not be detected in the same lane ahead if
they are traveling offset from the centerline
of the lane. A vehicle that is entering the
lane ahead may not be detected until the
vehicle has completely moved into the
lane.
If this occurs, the ICC system may warn
you by blinking the system indicator and
sounding the chime. The driver may
have to manually control the proper dis-
tance away from the vehicle traveling
ahead.

Action to take
When the conditions listed above are no
longer present, turn the system off using
the ICC CRUISE
switch. Turn the ICC
system back on to use the system.
Condition B
When the radar sensor area of the front
bumper is covered with dirt or is ob-
structed, the ICC system will automatically
be canceled. If the sensor area is covered
with ice, a transparent or translucent vinyl
bag, etc., the ICC system may not detect
vehicles ahead. In these instances, the ICC
system may not cancel and may not be
able to maintain the selected following dis-
tance from the vehicle ahead. Be sure to
check and clean the sensor area.
The system warning light (orange) will illu-
minate and the “Unavailable: Front Radar
Obstruction” warning message will appear
in the vehicle information display.
When driving on roads with limited road
structures or buildings (for example, or
long bridges, deserts, snow field, driving
next to long walls), the system may illumi-
nate the system warning light (orange) and
display the “Unavailable: Front Radar Ob-
struction” message. Action to take
If the warning light (orange) comes on, park
the vehicle in a safe location and turn the
engine off. Check to see if the sensor area
of the front bumper is blocked. If the sensor
area of the front bumper is blocked, re-
move the blocking material. Restart the
engine. If the warning light continues to
illuminate, have the ICC system checked. It
is recommended that you visit a NISSAN
dealer for this service.
Condition C
When the ICC system is not operating
properly, a chime sounds and the system
warning light (orange) will come on.Action to take
If the warning light comes on, park the ve-
hicle in a safe place. Turn the engine off,
restart the engine, resume driving and set
the ICC system again.
If it is not possible to set the system or
the indicator stays on, it may indicate
that the system is malfunctioning. Al-
though the vehicle is still drivable under
normal conditions, have the vehicle
checked. It is recommended that you
visit a NISSAN dealer for this service.
