2020 INFINITI QX50 brake

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 re-
lease the RES+ switch. The vehicle will re-
sume the last set cruising speed when the
vehicle speed is over 20 mph (30 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 traffic
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) [ft (m)]
1. Long 200 (60)
2. Middle 150 (45)
3. Short 100 (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 system
warns the driver with the chime and ICC sys-
tem display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance 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 vehicles
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, over- riding 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 ve-
hicle or on the side of the road. This may
cause the ICC system to decelerate or accel-
erate 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 vehicle.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driv-
ing position in the lane) or traffic or vehicle
condition (for example, if a vehicle is being
driven with some damage).
Acceleration when passing
When the ICC system is engaged above
44 mph and following a slower vehicle (be-
low ICC set speed), and the turn signal is
activated to the left, the ICC system will au-
tomatically start to accelerate the vehicle to
help initiate passing on the left and will begin
to reduce the distance to vehicle directly
ahead. Only the left side turn signal operates
this feature. As the driver steers the vehicle
and moves into the passing lane, if no vehicle
is detected ahead the ICC system will con- tinue to accelerate to the ICC system set
speed. If another vehicle is detected ahead,
then the vehicle will accelerate up to the fol-
lowing speed of that vehicle. If the vehicle is
not steered into the left lane to pass, the
acceleration will stop after a short time and
regain the set following distance. Accelera-
tion can be stopped at any point by depress-
ing the brake pedal or the CANCEL switch on
the steering wheel.
WARNING
In order to reduce the risk of a collision that
may result in serious injury or death, please
be aware of the following:
∙ This function is only activated with the
left turn signal and will briefly accelerate
the vehicle even if a lane change is not
initiated. This can include non-passing
situations such as left side exits.
∙ Ensure that when passing another ve- hicle, the adjacent lane is clear before ini-
tiating the pass. Sudden changes in traf-
fic may occur while passing- always
manually steer or brake as needed- never
solely rely on the system.

LIMITATIONS
WARNING
Listed below are the system limitations for
the ICC system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
∙ The ICC system is primarily intended foruse 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 automati- cally to road conditions. This system
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 dis-
tance control function, never rely solely
on the ICC system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding 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 standstill 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 manually con-
trol the proper following distance. The
ICC system may not be able to maintain
the selected distance between vehicles
(following distance) or selected vehicle
speed under some circumstances.

∙ The system may not detect the vehicle infront of you in certain road or weather
conditions. To avoid accidents, 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 vehicle may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources
∙ Do not use the ICC system if you are tow- ing a trailer. The system may not detect a
vehicle ahead. ∙ In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert and
avoid using the ICC system where not
recommended in this warning section.
The radar sensor will not detect the following
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 sensor generally detects the signals re-
turned from the vehicle ahead. Therefore, if
the sensor cannot detect the reflection from
the vehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which the
sensor cannot properly detect a vehicle ahead
and the system may not operate properly:
∙ When snow or road spray from traveling vehicles reduces the sensor’s detection.
∙ When your vehicle is towing a trailer, etc.
∙ When excessively heavy baggage is loaded in the rear seat or cargo area of
your vehicle. The ICC system is designed to automatically
check the sensor’s operation within the limi-
tations of the system.
When the sensor is covered with dirt or is
obstructed, the system will automatically be
canceled. If the sensor is covered with ice, a
transparent or translucent vinyl bag, etc., the
ICC system may not detect them. In these
instances, the vehicle-to-vehicle distance
control mode 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 regularly.
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the detec-
tion zone for the vehicle-to-vehicle distance
detection mode to maintain the selected dis-
tance 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 sound-
ing the chime. The driver may have to manu-
ally control the proper distance away from
vehicle traveling ahead.
