2019 INFINITI QX50 light

When the lower display is used to turn off the
system, the VDC system still operates to pre-
vent one drive wheel from slipping by trans-
ferring power to a non-slipping drive wheel.
The
indicator flashes if this occurs. All
other VDC functions are off and the
indicator will not flash.
The VDC system is automatically reset to on
when the ignition switch is placed in the OFF
position then back to the ON position.
The computer has a built-in diagnostic fea-
ture that tests the system each time you start
the engine and move the vehicle forward or in
reverse at a slow speed. When the self-test
occurs, you may hear a clunk noise and/or
feel a pulsation in the brake pedal. This is
normal and is not an indication of a malfunc-
tion.
WARNING
∙ The VDC system is designed to help the driver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully. ∙ Do not modify the vehicle’s suspension. If
suspension parts such as shock absorb-
ers, struts, springs, stabilizer bars, bush-
ings and wheels are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, the VDC system may not
operate properly. This could adversely
affect vehicle handling performance, and
the
indicator may flash or both
the
andindicator lights may
illuminate.
∙ If brake related parts such as brake pads, rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, the VDC system may not operate
properly and both the
and
the
indicator lights may illuminate.
∙ If engine control related parts are not INFINITI recommended or are extremely
deteriorated, both the
andindicator lights may illuminate. ∙ When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly
and the
indicator may flash or both
the
andindicator lights may
illuminate. Do not drive on these types of
roads.
∙ When driving on an unstable surface such as a turntable, ferry, elevator or ramp,
the
indicator may flash or both
the
andindicator lights may
illuminate. This is not a malfunction. Re-
start the engine after driving onto a
stable surface.
∙ If wheels or tires other than the INFINITI recommended ones are used, the VDC
system may not operate properly and
the
indicator may flash or both
the
andindicator lights may
illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow cov-
ered road.

BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of force
to each of the four wheels depending on the
radius of the turn.

Starting and driving5-183

The chassis control is an electric control mod-
ule that includes the following functions:∙ Active Trace Control
∙ Active Engine Brake
∙ Active Ride Control
ACTIVE TRACE CONTROL
This system senses driving based on the driv-
er’s steering and acceleration/braking pat-
terns, and controls brake pressure at indi-
vidual wheels to help smooth vehicle
response.
When the lower display is used to turn off the
VDC system, the Active Trace Control sys-
tem is also turned off.
If the Active Trace Control is not functioning
properly, the FEB with Pedestrian Detection
system warning indicator light illuminates in
the instrument panel.
The Active Trace Control can be set to on
(enabled) or off (disabled) through the lower
display “Infiniti Drive Mode Selector” menu
option.
ACTIVE ENGINE BRAKE
The Active Engine Brake function adds subtle
deceleration by controlling Continuously
Variable Transmission (CVT) gear ratio, de-
pending on the cornering condition calcu-
lated from the driver’s steering input and plu-
ral sensors. This benefit is for easier
traceability and less workload of adjusting
speed with braking at corners.
The Active Engine Brake also enhances brak-
ing feel by adding subtle deceleration with
CVT gear ratio control according to the driv-
er’s brake pedal operation
The Active Engine Brake can be set to on
(enabled) or off (disabled) through the lower
display “Infiniti Drive Mode Selector” menu
option.
CHASSIS CONTROL
5-184Starting and driving

When the Active Engine Brake is operated at
corners and the “Chassis Control” mode is
selected in the lower display, the Active En-
gine Brake graphics are shown in the vehicle
information display.
If the chassis control warning message ap-
pears in the vehicle information display, it
may indicate that the Active Engine Brake is
not functioning properly. Have the system
checked as soon as possible. It is recom-
mended that you visit an INFINITI retailer for
this service.WARNING
The Active Engine Brake may not be effec-
tive depending on the driving condition. Al-
ways drive carefully and attentively.
When the Active Engine Brake is operating,
the needle of the tachometer will rise up and
you may hear an engine noise. This is normal
and indicates that the Active Engine Brake is
operating properly.
ACTIVE RIDE CONTROL
This system senses upper body motion
(based on wheel speed information) and con-
trols engine torque and four wheel brake
pressure. This will enhance ride comfort in an
effort to restrain uncomfortable upper body
movement when passing over undulated
road surfaces. This system comes into effect
above 25 mph (40 km/h).
When the lower display is used to turn off the
VDC system, the Active Ride Control is also
turned off.
If the Integrated Dynamics-control Module
warning message appears in the vehicle in-
formation display, it may indicate that the
Active Ride Control is not functioning prop-
erly. Have the system checked as soon as
possible. It is recommended that you visit an
INFINITI retailer for this service.
When the Active Ride Control is operating,
you may hear noise and sense slight decel-
eration. This is normal and indicates that the
Active Ride Control is operating properly.

6-2In case of emergency

To shut off the engine in an emergency situ-
ation while driving, perform the following
procedure:
– Rapidly push the push-button ignitionswitch three consecutive times in less than
1.5 seconds, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires. When the low tire pres-
sure warning light is lit, and the “Tire Pressure
Low - Add Air” warning appears in the vehicle
information display, one or more of your tires
is significantly under-inflated. The system
also displays pressure of all tires (except the
spare tire) on the vehicle information display
screen by sending a signal from a sensor that
is installed in each wheel. If the vehicle is
being driven with low tire pressure, the TPMS
will activate and warn you of it by the low tire
pressure warning light. This system will acti-
vate only when the vehicle is driven at speeds
above 16 mph (25 km/h). For additional in-
formation, refer to “Warning lights, indicator
lights and audible reminders” in the “Instru-
ments and controls” section and “Tire Pres-
sure Monitoring System (TPMS)” in the
“Starting and driving” sections of this manual.
WARNING
∙ Radio waves could adversely affect elec-tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
∙ If the low tire pressure warning light illu- minates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage could
occur and may lead to an accident and
could result in serious personal injury.
Check the tire pressure for all four tires.
Adjust the tire pressure to the recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
OFF. If you have a flat tire, replace it with
a replacement tire as soon as possible.
EMERGENCY ENGINE SHUT OFF FLAT TIRE
In case of emergency6-3

∙ 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.
