2019 INFINITI QX50 air condition

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).
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 shift lever is not in the D (Drive) position or Manual mode
∙ When the electronic parking brake sys- tem is applied
∙ When the VDC system is turned off
∙ When VDC operates
∙ When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor
∙ When a wheel slips
∙ When the radar signal is temporarily in- terrupted

ICC system operation
The ICC system is designed to maintain a
selected distance from the vehicle in front of
you and can reduce the speed to match a
slower vehicle ahead. The system decelerates
the vehicle as necessary and if the vehicle
ahead comes to a stop, the vehicle deceler-
ates to a standstill. However, the ICC system
can only apply up to 40% of the vehicle’s total
braking power. This system should only be
used when traffic conditions allow vehicle
speeds to remain fairly constant or when ve-
hicle speeds change gradually. If a vehicle
moves into the traveling lane ahead or if a
vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
closer because the ICC system cannot decel-
erate the vehicle quickly enough. If this oc-
curs, the ICC system sounds a warning chime
and blinks the system display to notify the
driver to take necessary action.
The ICC system cancels and a warning chime
sounds if the speed is below approximately
15 mph (24 km/h) and a vehicle is not de-
tected ahead.The ICC system operates as follows:
∙ When there are no vehicles traveling ahead, the ICC system maintains the
speed set by the driver. The set speed
range is between approximately 20 and
90 mph (32 and 144 km/h).
∙ When there is a vehicle traveling ahead, the ICC system adjusts the speed to
maintain the distance, selected by the
driver, from the vehicle ahead. If the ve-
hicle ahead comes to a stop, the vehicle
decelerates to a standstill. Once your ve-
hicle stops, the ICC system keeps the ve-
hicle stopped.
∙ When your vehicle is stopped for less than 3 seconds and the vehicle ahead
begins to move, your vehicle will start
moving again automatically.
∙ When your vehicle is at a standstill for more than 3 seconds and the vehicle
ahead begins to accelerate, push the
RES+ switch or lightly depress the accel-
erator pedal. The ICC system starts to
follow the vehicle ahead.
∙ When the vehicle traveling ahead moves to a different traveling lane, the ICC sys-
tem accelerates and maintains vehicle
speed up to the set speed. The ICC system does not control vehicle
speed or warn you when you approach sta-
tionary and slow moving vehicles. You must
pay attention to vehicle operation to main-
tain proper distance from vehicles ahead
when approaching toll gates or traffic con-
gestion.

∙ When distance measurement becomesimpaired due to adhesion of dirt or ob-
struction to the sensor.
∙ When the radar signal is temporarily in- terrupted.
Action to take:
When the conditions listed above are no lon-
ger present, turn the system off using the
ProPILOT Assist switch. Turn the ProPILOT
Assist system back on to use the system.
NOTE:
When the ICC system is canceled under the
following conditions at a standstill, the elec-
tronic parking brake is automatically acti-
vated: ∙ Any door is open.
∙ The driver’s seat belt is not fastened.
∙ Your vehicle has been stopped by the ICC
system for approximately 3 minutes or
longer.
∙ The shift lever is not in the D (Drive) po-
sition or manual shift mode.
∙ The VDC system is turned off. ∙
When distance measurement becomes
impaired due to adhesion of dirt or ob-
struction to the sensor.
∙ When the radar signal is temporarily in-
terrupted.
Condition B
When the radar sensor of the front bumper is
covered with dirt or is obstructed, the ICC
system will automatically be canceled.
The chime will sound and the “Unavailable:
Front Radar Blocked” warning message will
appear in the vehicle information display.
Action to take:
If the warning message appears, stop the
vehicle in a safe place, press the Park button
to place the vehicle in the P (Park) position,
and turn the engine off. When the radar sig-
nal is temporarily interrupted, clean the sen-
sor area of the front bumper and restart the
engine. If the “Unavailable: Front Radar
Blocked” warning message continues to be
displayed, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
Condition C
When driving on roads with limited road
structures or buildings (for example, long bridges, deserts, snow fields, driving next to
long walls), the system may illuminate the
system warning light and display the “Un-
available: Front Radar Blocked” message.
Action to take:
When the above driving conditions no longer
exist, turn the system back on.
ICC system malfunction
If the ICC system malfunctions, it will be
turned off automatically, a chime will sound,
and the speed control status warning (or-
ange) will illuminate.
Action to take:
If the warning light comes on, stop the vehicle
in a safe place. Turn the engine off, restart
the engine and set the ICC system again. If it
is not possible to set the ICC system or the
indicator stays on, it may be a malfunction.
Although the normal driving can be contin-
ued, the ICC system should be inspected. It is
recommended that you visit an INFINITI re-
tailer for this service.
ICC sensor maintenance
The radar sensor is located on the front of the
vehicle.
Starting and driving5-127

NOTE:
If the driver lightly touches (instead of firmly
grips) the steering wheel, the steering
torque sensor may not detect the driver’s
hand(s) on the steering wheel and a sequence
of warnings may occur. When the driver
holds and operates the steering wheel again,
the warnings turn off.
Steering Assist limitations
WARNING
∙In the following situations, the camera may
not detect lane markers correctly or may
detect lane markers incorrectly and the
Steering Assist may not operate properly:

Follow these easy-to-use Fuel Efficient Driv-
ing Tips to help you achieve the most fuel
economy from your vehicle.1. Use Smooth Accelerator and Brake
Pedal Application
∙ Avoid rapid starts and stops.
∙ Use smooth, gentle accelerator and brake application whenever possible.
∙ Maintain constant speed while com- muting and coast whenever possible.
2. Maintain Constant Speed
∙ Look ahead to try and anticipate and minimize stops.
∙ Synchronizing your speed with traffic lights allows you to reduce your num-
ber of stops.
∙ Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency.
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
∙ Below 40 mph (64 km/h), it is more efficient to open windows to cool the
vehicle due to reduced engine load. ∙ Above 40 mph (64 km/h), it is more
efficient to use A/C to cool the vehicle
due to increased aerodynamic drag.
∙ Recirculating the cool air in the cabin when the A/C is on reduces cooling
load.
4. Drive at Economical Speeds and Dis-
tances
∙ Observing the speed limit and not ex- ceeding 60 mph (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
∙ Maintaining a safe following distance behind other vehicles reduces unnec-
essary braking.
∙ Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
∙ Select a gear range suitable to road conditions.
5. Use Cruise Control
∙ Using cruise control during highway driving helps maintain a steady speed. ∙ Cruise control is particularly effective
in providing fuel savings when driving
on flat terrains.
6. Plan for the Shortest Route
∙ Utilize a map or navigation system to determine the best route to save time.
7. Avoid Idling
∙ Shutting off your engine when safe for stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
∙ Automated passes permit drivers to use special lanes to maintain cruising
speed through the toll and avoid stop-
ping and starting.
9. Winter Warm Up
∙ Limit idling time to minimize impact to fuel economy.
∙ Vehicles typically need no more than 30 seconds of idling at start-up to ef-
fectively circulate the engine oil before
driving.
∙ Your vehicle will reach its ideal operat- ing temperature more quickly while
driving versus idling.
FUEL EFFICIENT DRIVING TIPS

∙ Read and understand the limitations ofthe sonar system as contained in this sec-
tion. Inclement weather may affect the
function of the sonar system; this may
include reduced performance or a false
activation.
∙ The system is deactivated at speeds above 6 mph (10 km/h). It is reactivated
at lower speeds.
∙ Inclement weather or ultrasonic sources such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem; this may include reduced perfor-
mance or a false activation.
∙ The system is not designed to prevent contact with small or moving objects. Al-
ways move slowly. The system will not
detect small objects below the bumper or
on the ground.
∙ The system may not detect the following objects: fluffy objects such as snow,
cloth, cotton, glass-wool, etc.; thin ob-
jects such as rope, wire and chain, etc.; or
wedge-shaped objects. ∙ The system may not detect objects at
speeds above 3 mph (5 km/h) and may
not detect certain angular or moving
objects.
SYSTEM TEMPORARILY
UNAVAILABLE
When sonar blockage is detected, the system
will be deactivated automatically.
The system is not available until the condi-
tions no longer exist.
The sonar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog. The blocked condition
may also be caused by objects such as ice,
frost or dirt obstructing the sonar sensors.
Action to take:
When the above conditions no longer exist,
the system will resume automatically.
SYSTEM MAINTENANCE
The sonar sensors are located on the front
and rear bumpers. Always keep the area near
the sonar sensors clean.
The sonar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog.
The blocked condition may also be caused by
objects such as ice, frost or dirt obstructing
the sonar sensors.
Check for and remove objects obstructing
the area around the sonar sensors.

5-190Starting and driving

∙ When replacing a wheel without TPMSsuch as the spare tire, TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you visit
an INFINITI retailer for these services.
∙ Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the TPMS.
∙ Do not inject any tire liquid or aerosol tire sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
RUN-FLAT TIRES
This vehicle is equipped with run-flat tires.
Run-flat tires can be used temporarily if they
are punctured. When the “Flat Tire — Visit
Dealer” warning appears in the vehicle infor-
mation display, one or more of your tires is
punctured. For additional information, refer
to “Run-flat tires” in the “Do-it-yourself” sec-
tion of this manual.
For additional information, refer to the tire
safety information in the Warranty Informa-
tion Booklet.
WARNING
∙ Although you can continue driving with apunctured run-flat tire, remember that
vehicle handling stability is reduced,
which could lead to an accident and per-
sonal injury. Also, driving a long distance
at high speeds may damage the tires.
∙ Do not drive at speeds above 50 mph (80 km/h) and do not drive more than
approximately 93 miles (150 km) with a
punctured run-flat tire. The actual dis-
tance the vehicle can be driven on a flat
tire depends on outside temperature, ve-
hicle load, road conditions and other
factors.
∙ Drive safely at reduced speeds. Avoid hard cornering or braking, which may
cause you to lose control of the vehicle.
∙ If you detect any unusual sounds or vi- brations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously dam-
aged and need to be replaced.
CAUTION
∙ Never install tire chains on a puncturedrun-flat tire, as this could damage your
vehicle.
∙ Avoid diving over any projection or pot- hole, as the clearance between the ve-
hicle and the ground is smaller than
normal.
∙ Do not enter an automated car wash with a punctured run-flat tire.
∙ Have the punctured tire inspected by an INFINITI retailer or other authorized re-
pair shop. Replace the tire as soon as pos-
sible if the tire is seriously damaged.
