2019 INFINITI QX50 warning light

– A sudden change in brightness occurs.(For example, when the vehicle enters
or exits a tunnel or a shaded area or
lightning flashes.)
– The poor contrast of a person to the background, such as having clothing
color or pattern which is similar to the
background.
– The pedestrian’s profile is partially obscured or unidentifiable due to the
pedestrian transporting luggage,
wearing bulky or very loose-fitting
clothing or accessories.
∙ The system performance may degrade in the following conditions:
– The vehicle is driven on a slippery road.
– The vehicle is driven on a slope.
– Excessively heavy baggage is loaded in the rear seat or the trunk room of
your vehicle. ∙ The system is designed to automatically
check the sensor’s (radar and camera)
functionality, within certain limitations.
The system may not detect blockage of
sensor areas covered by ice, snow or
stickers, for example. In these cases, the
system may not be able to warn the
driver properly. Be sure that you check,
clean and clear sensor areas regularly.
∙ In some road and traffic conditions, the FEB with Pedestrian Detection system
may unexpectedly apply partial braking.
When acceleration is necessary, depress
the accelerator pedal to override the
system.
∙ Excessive noise will interfere with the warning chime sound, and the chime may
not be heard.

ELECTRIC POWER STEERING
TYPE
WARNING
∙ If the engine is not running or is turned offwhile driving, the power assist for the
steering will not work. Steering will be
harder to operate.
∙ When the power steering warning light illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of the
vehicle, but the steering will be harder to
operate. Have the power steering system
checked. It is recommended that you visit
an INFINITI retailer for this service.
The power steering system is designed to
provide power assist while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assist for the
steering wheel will be reduced. This is to pre-
vent overheating of the power steering sys-
tem and protect it from getting damaged.
While the power assist is reduced, steering
wheel operation will become heavy. When
the temperature of the power steering sys-
tem goes down, the power assist level will return to normal. Avoid repeating such steer-
ing wheel operations that could cause the
power steering system to overheat.
You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the power steering system is not func-
tioning properly and may need servicing.
Have the power steering system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When the power steering warning light illu-
minates with the engine running, there will be
no power assist for the steering, but you will
still have control of the vehicle. At this time,
greater steering effort is required to operate
the steering wheel, especially in sharp turns
and at low speeds.
For additional information, refer to “Power
steering warning light” in the “Instruments
and controls” section of this manual.
DIRECT ADAPTIVE STEERING®
TYPE
WARNING
∙ When the power steering warning light
illuminates with the engine running, the
power assist for the steering will cease
operation. You will still have control of
the vehicle, but the steering will be
harder to operate.
∙ If wheels or tires other than the INFINITI recommended ones are used, Direct
Adaptive Steering® may not operate
properly and the power steering warning
light may illuminate.
∙ Do not modify the vehicle’s suspension parts such as chock absorbers, struts,
springs, stabilizer bars, bushings and
wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, Direct Adaptive Steering may not
operate properly and the power steering
warning light may illuminate.

∙ Do not modify the vehicle’s steering. Ifsteering parts are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, Direct Adaptive Steering
may not operate properly and the power
steering warning light may illuminate.
∙ If the Vehicle Dynamic Control (VDC) OFF indicator light illuminates, the
power steering warning light may also il-
luminate at the same time. Stop the ve-
hicle in a safe location, turn the engine off
and restart the engine. If the power
steering warning light continues to illu-
minate, have the system checked. It is
recommended that you visit an INFINITI
retailer for this service. For additional in-
formation, refer to “Vehicle Dynamic
Control (VDC) system” in this section.
CAUTION
∙ Do not place the ignition switch in the ON
position while the steering wheel or a tire
is removed.
∙ Do not turn the steering wheel as much as possible while the ignition switch is any
position other than the ON position.
∙ Installing an accessory on the steering wheel, or changing the steering wheel,
may reduce the steering performance. Direct Adaptive Steering is designed to con-
trol the steering force and steering angle ac-
cording to the vehicle speed and amount of
turning of the steering wheel.
The steering characteristic can be selected
using the INFINITI Drive Mode Selector. For
additional information, refer to “INFINITI
Drive Mode Selector” in this section.
If the VDC system is turned off, the setting of
steering becomes Standard mode.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate that Direct Adaptive Steering is not
functioning properly and may need servicing.
Have the system checked. It is recommended
that you visit an INFINITI retailer for this
service. For additional information, refer to
“Power steering warning light” in the “Instru-
ments and Controls” section of the manual.
When the power steering warning light illu-
minates with the engine running, the power
assist for the steering will cease operation.
You will still have control of the vehicle. How-
ever, greater steering effort will be needed,
especially in sharp turns and at low speeds.
If Direct Adaptive Steering is malfunctioning,
the steering wheel may turn slightly even
when driving on a straight road. Under the following conditions, the steering
wheel may turn slightly even when driving on
a straight road. This is due to a protection
mechanism for Direct Adaptive Steering. The
steering wheel will return to the normal posi-
tion after the protection mechanism is deac-
tivated.
Condition A:
∙ When the engine is stalled or likely to be stalled
∙ When the steering wheel is held in the full lock position or when the front tire
touches an obstruction
∙ When the battery is discharged
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and stop operating the steering wheel. Then
drive the vehicle for a short period of time.
Condition B: ∙ When the steering wheel is operated re- peatedly or continuously while parking or
driving at a very low speed. In this case,
the power assist for the steering wheel
will be reduced.
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and wait for a period of time, without oper-
