2023 INFINITI QX60 brake

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 tech-
niques. Reduce vehicle speed and be es-
pecially careful when driving and corner-
ing on slippery surfaces and always drive
carefully.
• Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
recommended for your vehicle or are ex-
tremely deteriorated, the VDC system
may not operate properly. This could ad-
versely affect vehicle handling perfor-
mance, and the
indicator light may
flash or both theandindicator
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 theindicator 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 light may flash or
both theandindicator 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 light may flash
or both theandindicator
lights may illuminate. This is not a mal-
function. Restart the engine after driv-
ing 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 light may flash or both
theandindicator lights may
illuminate.
• The VDC system is not a substitute for
winter tires or tire chains on a snow cov-
ered road. The chassis control is an electric control mod-
ule that includes the following functions:
• Active Trace Control
• Active Ride Control (if so equipped)
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 aid tracing at corners and
help smooth vehicle response.
When the PERSONAL mode is selected, the
Active Trace Control can be set to ON (en-
abled) or OFF (disabled). For additional infor-
mation see “INFINITI Drive Mode Selector”
(P. 5-29).
When the VDC system is turned off, the Ac-
tive Trace Control is also turned off.
Amount of brake control is changed depend-
ing on the mode selected by the INFINITI
Drive Mode Selector.
When the Active Trace Control is not func-
tioning properly, the master warning light il-
luminates, and the warning message “Chassis
Control System Error” will also appear in the
vehicle information display.
CHASSIS CONTROL
5-170Starting and driving

If the chassis control warning message ap-
pears in the vehicle information display, it
may indicate that the Active Trace Control 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. For additional information, see
“Vehicle information display warnings and in-
dicators” (P. 2-37) or (P. 2-60).
WARNING
The Active Trace Control may not be effec-
tive depending on the driving condition. Al-
ways drive carefully and attentively.
When the Active Trace Control is operating,
you may feel a pulsation in the brake pedal
and hear a noise. This is normal and indicates
that the Active Trace Control is operating
properly. You may also feel deceleration
when the Active Trace Control is operating.
However, this is not a malfunction.
ACTIVE RIDE CONTROL (if so
equipped)
This system senses upper body motion and
controls four wheel brake pressure. This will
enhance ride comfort in an effort to restrain
uncomfortable upper body movement when
passing over undulated road surfaces. When
the VDC system is turned off, the Active Ride
Control is also turned off.
If the chassis control warning message ap-
pears in the vehicle information display, it
may indicate that the Active Ride Control 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 Ride Control may not be effec-
tive depending on the driving condition. Al-
ways drive carefully and attentively.
When the Active Ride Control is operating,
you may feel a pulsation in the brake pedal
and hear a noise. This is normal and indicates
that the Active Ride Control is operating
properly. You may also feel deceleration
when the Active Ride Control is operating.
However, this is not a malfunction.
WARNING
• Never rely solely on the hill start assist
system to prevent the vehicle from mov-
ing backward on a hill. Always drive
carefully and attentively. Depress the
brake pedal when the vehicle is stopped
on a steep hill. Be especially careful when
stopped on a hill on frozen or muddy
roads. Failure to prevent the vehicle
from rolling backwards may result in a
loss of control of the vehicle and possible
serious injury or death.
• The hill start assist system is not de-
signed to hold the vehicle at a standstill
on a hill. Depress the brake pedal when
the vehicle is stopped on a steep hill. Fail-
ure to do so may cause the vehicle to roll
backwards and may result in a collision or
serious personal injury.
• The hill start assist system may not pre-
vent the vehicle from rolling backwards
on a hill under all load or road conditions.
Always be prepared to depress the brake
pedal to prevent the vehicle from rolling
backwards. Failure to do so may result in
a collision or serious personal injury.
HILL START ASSIST SYSTEM
Starting and driving5-171

When the vehicle is stopped on a hill, the hill
start assist system automatically keeps the
brakes applied to help prevent the vehicle
from rolling backward in the time it takes the
driver to release the brake pedal and apply
the accelerator.
The hill start assist system will operate auto-
matically under the following conditions:
• The transmission is shifted to a forward orreverse gear.
• The vehicle is stopped completely on a hill by applying the brake. The maximum hold-
ing time is 2 seconds. After 2 seconds the
vehicle will begin to roll back and the hill
start assist system will stop operating
completely.
The hill start assist system will not operate
when the shift position is placed in the N
(Neutral) or P (Park) position or on a flat and
level road. The sonar system sounds a tone to inform the
driver of obstacles around the vehicle using
the sonar sensors located in the front and
rear bumpers..
When the sonar system is turned on, the
sonar view will automatically appear in the
vehicle information display.
WARNING
• The sonar system is a convenience but it
is not a substitute for proper parking. •
The driver is always responsible for
safety during parking and other maneu-
vers. Always look around and check that
it is safe to do so before parking.
• Read and understand the limitations of
the sonar system as contained in this
section. The colors of the corner sonar
indicator indicates different distances to
the object.
• 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 sonar system is designed as an aid to
the driver in detecting large stationary
objects to help avoid damaging the
vehicle.
• The sonar system is not designed to pre-
vent contact with small or moving ob-
jects. Always move slowly. The system
will not detect small objects below the
bumper, and may not detect objects
close to the bumper or on the ground.
• The sonar system may not detect the fol-
lowing objects: fluffy objects such as
snow, cloth, cotton, glass, wool, etc.;
thin objects such as rope, wire and chain,
etc.; or wedge-shaped objects.

WARNING
Listed below are the system limitations for
the sonar system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
• Read and understand the limitations of
the sonar system as contained in this
section. Inclement weather may affect
the function of the sonar system; this
may include reduced performance or a
false activation.
• The sonar system is deactivated at
speeds above 6 mph (10 km/h). It is re-
activated at lower speeds.
• Inclement weather or ultrasonic sources
such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic

• If the sonar sensors are dirty, wipe them offwith a soft cloth while being careful to not
damage them.
• The sonar sensors may be blocked by tem- porary ambient conditions such as splash-
ing water, mist or fog. The blocked condi-
tion may also be caused by objects such as
ice, frost or dirt obstructing the sonar sen-
sors. Check for and remove objects ob-
structing the area around the sonar
sensors.
• Do not subject the area around the sonar sensors to strong impact. Also, do not re-
move or disassemble the sonar sensors. If
the sonar sensors and peripheral areas are
deformed in an accident, etc., have the so-
nar sensors checked by an INFINITI retailer.
• Do not attach stickers (including transpar- ent material), install accessories or apply
additional paint on the sonar sensors and
their surrounding areas. This may cause a
malfunction or improper operation.
• When washing the vehicle using a high- pressure washer, do not apply direct
washer pressure on the sonar sensors. This
may cause a malfunction of the sonar
sensors. The Idling Stop System activates to prevent
unnecessary fuel consumption, exhaust
emissions and noise.
• When you stop the vehicle, the engine is
turned off automatically.
• When you release the brake pedal to begin moving again, the engine is turned on
automatically.
