2019 INFINITI QX50 brake

– When driving with a tire that is notwithin normal tire conditions (for ex-
ample, tire wear, abnormal tire pres-
sure, installation of a spare tire, tire
chains, nonstandard wheels)
– When the vehicle is equipped with non-original brake or suspension
parts
– When an object that obstructs the camera unit detection range is
attached
– When excessively heavy baggage is loaded in the rear seat or luggage area
of your vehicle
– When the vehicle load capacity is exceeded
– When towing a trailer or other vehicle
∙ Excessive noise will interfere with the warning chime sound, and the beep may
not be heard. ∙ For the ProPILOT Assist system to oper-
ate properly, the windshield in front of
the camera must be clean. Replace worn
wiper blades. The correct size wiper
blades must be used to help make sure the
windshield is kept clean. Only use Genu-
ine INFINITI wiper blades, or equivalent
wiper blades, that are specifically de-
signed for use on your vehicle model and
model year. It is recommended that you
visit your INFINITI retailer for the correct
parts for your vehicle.
Steering Assist temporary standby
Automatic standby due to driving operation:
When the driver activates the turn signal, the
Steering Assist is temporarily placed in a
standby mode. (The Steering Assist restarts
automatically when the operating conditions
are met again.)
Automatic standby:
In the following cases, a warning message is
displayed along with the chime, and the
Steering Assist is placed in a temporary
standby mode. (The Steering Assist restarts
automatically when the operating conditions
are met again.) ∙ When lane markers on both sides are no
longer detected
∙ When a vehicle ahead is no longer de- tected under approximately 37 mph
(60 km/h)
Steering Assist cancel
Under the following conditions, the Steering
Assist cancels, and the Steering Assist status
indicator and the Steering Assist indicator
turn off:
∙ When unusual lane markers appear in the traveling lane or when the lane marker
cannot be correctly detected for some
time due to certain conditions (for ex-
ample, a snow rut, the reflection of light
on a rainy day, the presence of several
unclear lane markers)
∙ When the windshield wiper operates in the low (LO) or high (HI) speed operation
(the Steering Assist is disabled when the
wiper operates for more than approxi-
mately 10 seconds)
NOTE:
For vehicles with auto wipers, the wipers may
automatically switch to LO or HI. If the auto
wipers remain in LO or HI for longer than
10 seconds, the steering assist will cancel.

To cancel the preset speed, use any of the
following methods:1. Push the CANCEL switch. The vehicle speed indicator will turn off.
2. Tap the brake pedal. The vehicle speed indicator will turn off.
3. Turn the ProPILOT Assist switch off. Both the cruise indicator and vehicle
speed indicator will turn off.
To reset at a faster cruising speed, use one of
the following three methods: 1. Depress the accelerator pedal. When the vehicle attains the desired speed, push
and release the SET- switch.
2. Push and hold the RES+ switch. When the vehicle attains the desired speed, re-
lease the switch.
3. Push, then quickly release the RES+ switch. Each time you do this, the set
speed will increase by about 1 mph
(1.6 km/h).
To reset at a slower cruising speed, use one
of the following three methods: 1. Lightly tap the brake pedal. When the vehicle attains the desired speed, push
the SET- switch and release it. 2. Push and hold the SET- switch. Release
the switch when the vehicle slows down
to the desired speed.
3. Push, then quickly release the SET- switch. Each time you do this, the set
speed will decrease by about 1 mph
(1.6 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 25 mph (40 km/h).WARNING
Failure to follow the warnings and instruc-
tions for proper use of the DCA system
could result in serious injury or death.
∙ Always drive carefully and attentively when using the DCA system. Read and
understand the Owner’s Manual thor-
oughly before using the DCA system. To
avoid serious injury or death, do not rely
on the system to prevent accidents or to
control the vehicle’s speed in emergency
situations. Do not use the DCA system
except in appropriate road and traffic
conditions.
∙ The system is only an aid to assist the driver and is not a collision warning or
avoidance device. It is the driver’s re-
sponsibility to stay alert, drive safely and
be in control of the vehicle at all times.
DISTANCE CONTROL ASSIST (DCA)
(if so equipped)
5-138Starting and driving

∙ As there is a performance limit to the dis-tance control function, never rely solely
on the DCA 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.
∙ Always pay attention to the operation of the vehicle and be ready to manually de-
celerate to maintain the proper following
distance. The DCA system may not be
able to decelerate the vehicle under some
circumstances.
∙ This system only brakes and moves the accelerator pedal upward to help assist
the driver to maintain a following dis-
tance from the vehicle ahead. Accelera-
tion should be operated by the driver.
∙ The DCA system does not control the ve- hicle speed or warn you when you ap-
proach stationary and slow moving ve-
hicles. You must pay attention to vehicle
operation to maintain proper distance
from vehicles ahead. ∙ The DCA system automatically deceler-
ates your vehicle to help assist the driver
to maintain a following distance from the
vehicle ahead. Manually brake when de-
celeration is required to maintain a safe
distance upon sudden braking by the ve-
hicle ahead or when a vehicle suddenly
appears in front of you. Always stay alert
when using the DCA system.
∙ If the vehicle ahead comes to a stop, the vehicle decelerates to a standstill within
the limitations of the system. The system
will cancel with a warning chime once it
judges that the vehicle has come to a
standstill. To prevent the vehicle from
moving, the driver must depress the
brake pedal.
The DCA system is intended to assist the
driver in keeping a following distance from
the vehicle ahead traveling in the same lane
and direction.
If the radar sensor detects a slower moving
vehicle ahead, the system will reduce the ve-
hicle speed to help assist the driver to main-
tain a following 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 approxi-
mately 650 ft (200m) ahead.

DCA SYSTEM OPERATION
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the DCA system
could result in serious personal injury or
death.
∙ When the vehicle ahead detection indica-tor light is not illuminated, the system
will not control the vehicle or warn the
driver.
∙ Never place your foot under the brake pedal. Your foot may be caught when the
system controls the brake.
∙ Depending on the position of the accel- erator pedal, the system may not be able
to assist the driver to release the accel-
erator pedal appropriately.

5-140Starting and driving

The DCA system brakes and moves the ac-
celerator pedal upward according to the dis-
tance from and the relative speed of the ve-
hicle ahead to help assist the driver in
maintaining a following distance. The system
will decelerate as necessary and if the vehicle
ahead comes to a stop, the vehicle deceler-
ates to a standstill. However, the DCA sys-
tem can only apply up to approximately 40%
of the vehicle’s total braking power. If a ve-
hicle moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
closer because the DCA system cannot de-
celerate the vehicle quickly enough. If this
occurs, the DCA system will sound a warning
chime and blink the system display to notify
the driver to take necessary action. For addi-
tional information, refer to “Approach warn-
ing” in this section.The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelerator
pedal upward in the normal driving condition.
When a vehicle is detected ahead:
The vehicle ahead detection indicator comes
on.When vehicle approaches a vehicle ahead:
∙ If the driver’s foot is not on the accelera- tor pedal, the system activates the brakes
to decelerate smoothly as necessary. If
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system.
∙ If the driver’s foot is on the accelerator pedal, the system moves the accelerator
pedal upward to assist the driver to re-
lease the accelerator pedal.
When brake operation by driver is required:
The system alerts the driver by a warning
chime and blinking the vehicle ahead detec-
tion indicator. If the driver’s foot is on the
accelerator pedal after the warning, the sys-
tem moves the accelerator pedal upward to
assist the driver to switch to the brake pedal.
NOTE: ∙ The stop lights of the vehicle come on
when braking is performed by the DCA
system.
∙ When the brake operates, a noise may be
heard. This is not a malfunction.

Starting and driving5-141

Overriding the system:
The following driver’s operations override the
system operation:∙ When the driver depresses the accelera- tor pedal even further while the system is
moving the accelerator pedal upward,
the DCA system control of the accelera-
tor pedal is canceled.
∙ When the driver’s foot is on the accelera- tor pedal, the brake control by the system
is not operated.
∙ When the driver’s foot is on the brake pedal, neither the brake control nor the
alert by the system operates.
∙ When the ICC system is set, the DCA system will be canceled.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 DCA
system 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 your
vehicle approaches vehicles that are parked
or moving slowly. NOTE:
The approach warning chime may sound and
the system display may blink when the radar
sensor detects objects on the side of the
road. This may cause the DCA system to de-
celerate or accelerate the vehicle. The radar
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 manu-
ally 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).

DCA SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations of
the DCA system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
∙ This system will not adapt automaticallyto road conditions. Do not use the system
on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
∙ The DCA system will not apply brake control while the driver’s foot is on the
accelerator pedal.
∙ As there is a performance limit to the dis- tance control function, never rely solely
on the DCA 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. ∙ The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the DCA 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.
– On off-road surfaces such as on sand or rock, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the sensor area of the front bumper
– On steep downhill roads (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
– When towing a trailer or other vehicle
– Interference by other radar sources ∙ In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to con-
trol the distance from other vehicles us-
ing the accelerator pedal. Always stay
alert and avoid using the DCA system
when it is not recommended in this
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 following are some conditions in which
the sensor cannot detect the signals: ∙ When the snow or road spray from trav- eling vehicles reduces the sensor’s visibil-
ity
∙ When excessively heavy baggage is loaded in the rear seat or the luggage
room of your vehicle

1. Vehicle ahead detection indicator
2. FEB with Pedestrian Detection emer-gency warning indicator
3. FEB with Pedestrian Detection system warning light
SYSTEM OPERATION
The FEB with Pedestrian Detection system
operates at speeds above approximately
3 mph (5 km/h). For the pedestrian detection
function, the FEB with Pedestrian Detection
system operates at speeds between 6 –
37 mph (10 – 60 km/h).
If a risk of a forward collision with a vehicle is
detected, the FEB with Pedestrian Detection
system will first provide a warning to the
driver by flashing the vehicle ahead detection
indicator and providing an audible alert. In
addition, the FEB with Pedestrian Detection
system pushes the accelerator pedal up, and
then the system applies partial braking. If the
driver applies the brakes quickly and force-
fully, but the FEB with Pedestrian Detection
system detects that there is still the possibility
of a forward collision, the system will auto-
matically increase the braking force. If the risk of a collision becomes imminent
and the driver does not take action, the FEB
with Pedestrian Detection system issues the
second warning to the driver by flashing the
FEB with Pedestrian Detection emergency
warning indicator (red), providing an audible
warning, and then automatically applies
harder braking.
If a risk of a forward impact with a pedestrian
is detected, the FEB with Pedestrian Detec-
tion system will provide a warning to the
driver by flashing the FEB with Pedestrian
Detection emergency warning indicator (red),
provides an audible alert and the system will
apply partial baking. If the driver applies the
brakes quickly and forcefully but the FEB
with Pedestrian Detection system detects
that there is still the possibility of a forward
impact with a pedestrian, the system will au-
tomatically increase the braking force. If the
risk of collision becomes imminent and the
driver does not take action, the FEB with
Pedestrian Detection system automatically
applies harder braking.
NOTE:
The vehicle’s brake lights come on when any
braking is performed by the FEB with Pedes-
trian Detection system.
Depending on vehicle speed and distance to
the vehicle or pedestrian ahead, as well as
driving and roadway conditions, the system
may help the driver avoid a forward collision
or may help mitigate the consequences if a
collision should be unavoidable. If the driver is
handling the steering wheel, accelerating or
braking, the FEB with Pedestrian Detection
system will function later or will not function.
The automatic braking will cease under the
following conditions:
∙ When the steering wheel is turned to avoid a collision.
∙ When the accelerator pedal is depressed.
∙ When there is no longer a vehicle or a pedestrian detected ahead.
If the FEB with Pedestrian Detection system
has stopped the vehicle, the vehicle will re-
main at a standstill for approximately 2 sec-
onds before the brakes are released.
