2020 NISSAN ALTIMA brake

duce the vehicle speed so that your vehicle
follows the vehicle in front at the selected
distance.
The system automatically controls the
throttle and applies the brakes (up to ap-
proximately 40% of vehicle braking power)
if necessary.
The detection range of the sensor is ap-
proximately 650 f t (200 m) ahead.

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the speed
to maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway,
the ICC system will accelerate and main-
tain the speed up to the set speed. Pay
attention to the driving operation to main-
tain control of the vehicle as it accelerates
to the set speed.
The vehicle may not maintain the set
speed on winding or hilly roads. If this oc-
curs, you will have to manually control the
vehicle speed.Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is re-
quired for a lane change. Depress the brake
pedal when deceleration is required to
maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when us-
ing the ICC system.VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE SWITCHES
The system is operated by the ICC switch
and four control switches, all mounted on
the steering wheel.
1. CANCEL switch:
Deactivates the system without eras-
ing the set speed.
2. RES+ switch:
Resumes set speed or increases
speed incrementally.

The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem maintains the set vehicle speed, simi-
lar to standard cruise control, as long as no
vehicle is detected in the lane ahead. The
ICC system displays the set speed. Vehicle detected ahead
When a vehicle is detected in the lane
ahead, the ICC system decelerates the ve-
hicle by controlling the throttle and apply-
ing the brakes to match the speed of a
slower vehicle ahead. The system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.
NOTE:
∙ The stop lights of the vehicle come on
when braking is performed by the ICC
system.
∙ When the brake operates, a noise may
be heard. This is not a malfunction.
When a vehicle ahead is detected, the ve-
hicle ahead detection indicator comes on.
The ICC system will also display the set
speed and selected distance.
Vehicle ahead not detected
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.

When a vehicle is no longer detected, the
vehicle ahead detection indicator turns off.
If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system con-
trols the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 mph (24 km/h), the sys-
tem will be canceled.When passing another vehicle,the set
speed indicator
Awill flash when the ve-
hicle speed exceeds the set speed. The ve-
hicle detect indicator will turn off when the
area ahead of the vehicle is open. When the
pedal is released, the vehicle will return to
the previously set speed.
Even though your vehicle speed is set in the
ICC system, you can depress the accelera-
tor pedal when it is necessary to accelerate
your vehicle rapidly.
How to change the set vehicle
speed
To cancel the preset speed, use one of the
following methods:
∙ Push the CANCEL switch. The set ve- hicle speed indicator will go out.
∙ Tap the brake pedal. The set vehicle speed indicator will go out.
∙ Turn the ICC switch off. The ICC indica- tors will go out.
To reset at a faster cruising speed, use
one of the following methods:
∙ Depress the accelerator pedal. When the vehicle attains the desired speed,
push and release the SET– switch.
∙ Push and hold the RES+ switch. The set vehicle speed will increase by approxi-
mately 5 mph (5 km/h).
∙ Push, then quickly release the RES+ switch. Each time you do this, the set
speed will increase by approximately
1 mph (1 km/h).

To reset at a slower cruising speed,use
one of the following methods:
∙ Lightly tap the brake pedal. When the vehicle attains the desired speed, push
the SET– switch and release it.
∙ Push and hold the SET– switch. The set vehicle speed will decrease by approxi-
mately 5 mph (5 km/h).
∙ Push, then quickly release the SET– switch. Each time you do this, the set
speed will decrease by approximately
1 mph (1 km/h).
To resume the preset speed, push and
release the RES+ switch. The vehicle will
resume the last set cruising speed when
the vehicle speed is over 20 mph (32 km/h).
How to change the set distance
to the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traf-
fic conditions.
Each time the distance
switchAis
pushed, the set distance will change to
long, middle, short and back to long again,
in that sequence.
Distance Approximate distance at
60 mph (100 km/h) [f t (m)]
1. Long 200 (60)
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.
∙ The distance setting will remain at the current setting even if the engine is re-
started.

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).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed: ∙ When the vehicle ahead is not detected and your vehicle is traveling below the
speed of 15 mph (24 km/h)
∙ When the system judges the vehicle is at a standstill
∙ When the shif t lever is not in the D (Drive) position, Manual mode or L (Low) range.
∙ When the parking brake system is ap- plied
∙ When the VDC system is turned off
∙ When VDC operates
∙ When distance measurement be- comes impaired due to adhesion of dirt
or obstruction to the sensor
∙ When a wheel slips
∙ When the radar signal is temporarily in- terrupted

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE LIMITATIONS
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The ICC system is primarily intendedfor use on straight, dry, open roads
with light traffic. It is not advisable to
use the ICC system in city traffic or
congested areas.
∙ The ICC system will not adapt auto- matically to road conditions. This sys-
tem should be used in evenly flowing
traffic. Do not use the system on roads
with sharp curves, or on icy roads, in
heavy rain or in fog. ∙ As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absentminded driving, or over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the ve-
hicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
∙ If the vehicle ahead comes to a stop, the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel once it judges
that the vehicle has come to a stand-
still and sound a warning chime. To
prevent the vehicle from moving, the
driver must depress the brake pedal.
∙ Always pay attention to the operation of the vehicle and be ready to manu-
ally control the proper following dis-
tance. The ICC system may not be able
to maintain the selected distance be-
tween vehicles (following distance) or
selected vehicle speed under some
circumstances. ∙ 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
