check engine INFINITI QX60 2018 Service Manual

SYSTEM MALFUNCTION
If the BCI system malfunctions, it will turn off
automatically, a chime will sound and the BCI
system warning light (orange) will illuminate.
Action to take:
Stop the vehicle in a safe location, turn the
engine off and restart the engine. If the warn-
ing light (orange) continues to illuminate,
have the system checked. It is recommended
that you visit an INFINITI retailer for this
service.
SYSTEM MAINTENANCE
The radar sensors1and the sonar sensors
2for the BCI system are located near the
rear bumper. Always keep the area near the
radar sensors clean.
The radar 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 radar sensors.
Check for and remove objects obstructing
the area around the radar sensors. Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the radar sensors.
Do not strike or damage the area around the
radar sensors. It is recommended that you
visit an INFINITI retailer if the area around
the radar sensors is damaged due to a colli-
sion.

SYSTEM TEMPORARILY
UNAVAILABLE
When radar blockage is detected, the system
will be deactivated automatically. The “Un-
available: Side Radar Obstruction” warning
message will appear and the BSW/RCTA in-
dicator (white) will blink
Ain the vehicle in-
formation display.
The systems are not available until the condi-
tions no longer exist.
The radar 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 radar sensors.
NOTE:
If the BSW system stops working, the RCTA
system will also stop working.
Action to take
When the above conditions no longer exist,
the system will resume automatically.
Malfunction
When the RCTA system malfunctions, it will
turn off automatically. The system malfunc-
tion warning message with the BSW/RCTA
indicator (orange) will appear in the vehicle
information display.
NOTE:
If the BSW system stops working, the RCTA
system (if so equipped) will also stop work-
ing.
Action to take
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off and restart the engine. If the mes-
sage continues to appear, have the system
checked. It is recommended that you visit an
INFINITI retailer for this service.
SYSTEM MAINTENANCE
The two radar sensors1for the BSW and
RCTA systems are located near the rear
bumper. Always keep the area near the radar
sensors clean.
The radar 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

∙ If the engine coolant temperature be-comes excessively high, the cruise control
system will be canceled automatically.
∙ If the SET indicator blinks, turn the ON/OFF switch off and have the system
checked. It is recommended that you visit
an INFINITI retailer for this service.
∙ The SET indicator may sometimes blink when the ON/OFF switch is turned on
while pushing the ACCEL/RES,
COAST/SET or CANCEL switch. To
properly set the cruise control system,
perform the steps below.
WARNING
Do not use the cruise control when driving
under the following conditions:
∙ When it is not possible to keep the vehicleat a set speed
∙ In heavy traffic or in traffic that varies in speed
∙ On winding or hilly roads
∙ On slippery roads (rain, snow, ice, etc.)
∙ In very windy areas
Doing so could cause a loss of vehicle con-
trol and result in an accident.
CRUISE CONTROL OPERATIONS
The cruise control allows driving at a speed
between 25 - 89 mph (40 - 144 km/h) with-
out keeping your foot on the accelerator
pedal.
To turn on the cruise control, push the
ON/OFF switch on. The CRUISE indicator
light in the vehicle information display will
illuminate.
To set cruising speed, accelerate the vehicle
to the desired speed, push the COAST/SET
switch and release it. The SET indicator light
in the vehicle information display will illumi-
nate. Take your foot off the accelerator
pedal. Your vehicle maintains the set speed.
∙ To pass another vehicle, depress the ac-
celerator pedal. When you release the
pedal, the vehicle returns to the previ-
ously set speed.
∙ The vehicle may not maintain the set speed when going up or down steep hills.
If this happens, drive without the cruise
control. To cancel the preset speed,
use one of the
following three methods:
∙ Push the CANCEL switch; the SET indi- cator light in the vehicle information dis-
play goes out.
∙ Tap the brake pedal; the SET indicator light goes out.
∙ Push the ON/OFF switch off. Both the CRUISE indicator light and SET indicator
light in the vehicle information display go
out.
The cruise control is automatically canceled
and the SET light in the vehicle information
display goes out if: ∙ You depress the brake pedal while push- ing the ACCEL/RES or SET/COAST
switch. The preset speed is deleted from
memory.
∙ The vehicle slows down more than 8 mph (13 km/h) below the set speed.
∙ You move the shift lever to N (Neutral).
To reset at a faster cruising speed, use one of
the following three methods:
∙ Depress the accelerator pedal. When the vehicle attains the desired speed, push
and release the COAST/SET switch.

If the AWD error warning message is dis-
played, there may be a malfunction in the
Intelligent AWD system. Reduce vehicle
speed and have your vehicle checked as soon
as possible. It is recommended that you visit
an INFINITI retailer for this service.The AWD high temperature message may be
displayed while trying to free a stuck vehicle
due to increased oil temperature. The driving
mode may change to 2-wheel drive. If this
message is displayed, stop the vehicle with
the engine idling, as soon as it is safe to do so.
Then if the message turns off, you can con-
tinue driving.The tire size message may be displayed if
there is a large difference between the diam-
eters of front and rear wheels. Pull off the
road in a safe area, with the engine idling.
Check that all tire sizes are the same, that the
tire pressure is correct and that the tires are
not excessively worn.
If any warning messages continue to be dis-
played, have your vehicle checked as soon as
possible. It is recommended that you visit an
INFINITI retailer for this service.

WARNING
∙ Do not drive beyond the performance ca-pability of the tires. Accelerating quickly,
sharp steering maneuvers or sudden
braking may cause loss of control, even
with Intelligent AWD engaged.
∙ For AWD equipped vehicles, do not at- tempt to raise two wheels off the ground
and shift the transmission to any drive or
reverse position with the engine running.
Doing so may result in drivetrain damage
or unexpected vehicle movement which
could result in serious personal injury or
vehicle damage.
∙ Do not attempt to test an AWD equipped vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing) or similar
equipment even if the other two wheels
are raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer. Us-
ing the wrong test equipment may result
in drivetrain damage or unexpected ve-
hicle movement which could result in se-
rious personal injury or vehicle damage.
CAUTION
∙ Do not operate the engine on a free rollerwhen any of the wheels are raised.
∙ If you use the free roller, rotate four wheels with the same speed without rais-
ing any wheels.
∙ If an AWD warning message is displayed while driving there may be a malfunction
in the AWD system. Reduce the vehicle
speed immediately and have your vehicle
checked as soon as possible. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
∙ The powertrain may be damaged if you continue driving when the AWD tem-
perature or tire size incorrect messages
are displayed
∙ If the AWD high temperature message is displayed while you are driving, pull off
the road in a safe area, and idle the en-
gine. The driving mode will change to
2WD to prevent the AWD system from
malfunctioning. If the warning message
turns off, you can drive again. ∙ If the tire size incorrect message is dis-
played while you are driving, pull off the
road in a safe area with the engine idling.
Check that all tire sizes are the same, that
the tire pressure is correct and that the
tires are not excessively worn.
∙ If a warning message continues to be dis- played after the above operations, have
your vehicle checked as soon as possible.
It is recommended that you visit an
INFINITI retailer for this service.
