INFINITI QX 2011 Owners Manual

When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the ICC sensor may detect
vehicles in a different lane, or may temporarily
not detect a vehicle traveling ahead. This may
cause the ICC system to decelerate or acceler-
ate the vehicle.The detection of vehicles may also be affected
by vehicle operation (steering maneuver or trav-
eling position in the lane, etc.) or vehicle con-
dition.
If this occurs, the ICC system may warn
you by blinking the system indicator and sound-
ing the chime unexpectedly. You will have to
manually control the proper distance away from
the vehicle traveling ahead. When driving on the freeway at a set speed and
approaching a slower traveling vehicle ahead,
the ICC system will adjust the speed to maintain
the distance, selected by the driver, from the
vehicle ahead. If the vehicle ahead changes
lanes or exits the freeway, the ICC system will
accelerate and maintain the speed up to the set
speed. Pay attention to the driving operation to
maintain control of the vehicle as it accelerates
to the set speed.
The vehicle may not maintain the set speed on
winding or hilly roads. If this occurs, you will
have to manually control the vehicle speed.

System operation
WARNING
Normally when controlling the distance to a
vehicle ahead, this system automatically accel-
erates or decelerates your vehicle according to
the speed of the vehicle ahead. Depress the
accelerator to properly accelerate your vehicle
when acceleration is required for a lanechange. Depress the brake pedal when decel-
eration is required to maintain a safe distance
to the vehicle ahead due to its sudden braking
or if a vehicle cuts in. Always stay alert when
using the Intelligent Cruise Control (ICC)
system.
The driver sets the desired vehicle speed based
on the road conditions. The ICC system main-
tains the set vehicle speed, similar to standard
cruise control, as long as no vehicle is detected
in the lane ahead.
The ICC system displays the set speed. Vehicle detected ahead :
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by con-
trolling the throttle and applying the brakes to
match the speed of a slower vehicle ahead. The
system then controls the vehicle speed based
on the speed of the vehicle ahead to maintain
the driver selected distance.
The stoplights of the vehicle come on when brak-
ing is performed by the ICC system.
When the brake operates, a noise may be heard
or felt. This is not a malfunction.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and
selected distance.
Vehicle ahead not detected :
When a vehicle is no longer detected ahead, the
ICC system gradually accelerates your vehicle to
resume the previously set vehicle speed. The
ICC system then maintains the set speed.
When a vehicle is no longer detected the vehicle
ahead detection indicator turns off.
If a vehicle ahead appears during acceleration
to the set vehicle speed or any time the ICC
system is in operation, the system controls the
distance to that vehicle.

When a vehicle is no longer detected under
approximately 15 MPH (24 km/h), the system
will be cancelled.When passing another vehicle,the set vehicle
speed indicator will flash when the vehicle
speed exceeds the set speed. The vehicle detect
indicator will turn off when the area ahead of
the vehicle is open. When the pedal is released,
the vehicle will return to the previously set
speed.
Even though your vehicle speed is set in the ICC
system, you can depress the accelerator pedal
when it is necessary to accelerate your vehicle
rapidly.How to change set vehicle speed
To cancel the preset speed, use any of these
methods:
● Push the CANCEL switch. The set vehicle
speed indicator will go out.
● Tap the brake pedal. The set vehicle speed
indicator will go out.
● Turn the MAIN switch off. Both the MAIN
switch indicator and set vehicle speed indi-
cator will go out.
To reset at a faster cruising speed, use one of
the following methods:
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the SET/COAST switch.
● Push and hold the RESUME/ACCELERATE
switch. The set vehicle speed will increase
by approximately 5 MPH or 5 km/h.
● Push, then quickly release the
RESUME/ACCELERATE switch. Each time you
do this, the set speed will increase by
approximately 1 MPH or 1 km/h.
SSD1108
5-52Starting and driving

To reset at a slower cruising speed,use one of
the following methods:
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
SET/COAST switch and release it.
● Push and hold the SET/COAST switch. The
set vehicle speed will decrease by approxi-
mately 5 MPH or 5 km/h.
● Push, then quickly release the SET/COAST
switch. Each time you do this, the set speed
will decrease by approximately 1 MPH or 1
km/h.
To resume the preset speed, push and release
the RESUME/ACCELERATE switch. The vehicle
will resume the last set cruising speed when the
vehicle speed is over 20 MPH (32 km/h).
How to change set distance to
vehicle ahead
The distance to the vehicle ahead can be se-
lected at any time depending on the traffic
conditions.
Each time the DISTANCE switch
Ais pushed,
the set distance will change to long, middle,
short and back to long again in that sequence.
SSD0967
Starting and driving5-53

●The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the
distance. ●
If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that vehicle
or if another vehicle cuts in, the system warns
the driver with the chime and Intelligent Cruise
Control (ICC) system display. Decelerate by
depressing the brake pedal to maintain a safe
vehicle distance if:
● The chime sounds.
● The vehicle ahead detection and set dis-
tance indicator blink.
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 in-
creasing
● When a vehicle cuts in near your vehicle
The warning chime will not sound in the follow-
ing cases:
● When your vehicle approaches vehicles that
are parked or moving slowly
● When the accelerator pedal is depressed,
overriding the system
SSD1109
5-54Starting and driving

NOTE:
The approach warning chime may sound and the
system display may blink when the ICC sensor
detects some reflectors
Awhich are fitted on
vehicles in other lanes or on the side of the road.
This may cause the ICC system to decelerate or
accelerate the vehicle. The ICC sensor may de-
tect these reflectors when the vehicle is driven
on winding roads, hilly roads or when entering
or exiting a curve. The ICC sensor may also de-
tect reflectors on narrow roads or in road con-
struction zones. 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 driving
position in the lane) or traffic or vehicle condi-
tion (for example, if a vehicle is being driven
with some damage).
Automatic cancellation
A chime sounds under the following conditions
and the control is automatically canceled.
●
When the vehicle speed falls below approxi-
mately 15 MPH (24 km/h)
● When the system judges the vehicle is at a
standstill
● When the selector lever is shifted to the N
(Neutral) position
● When the windshield wipers are operating at
high speed. The system may cancel when
the wipers are set to the AUTO position.
● When the VDC is turned off
● When the ABS or VDC operates
● When the parking brake is applied
● When the SNOW mode switch is pushed on.
● When the 4WD shift switch is in the 4H or 4L
position (for 4WD models) ●
When driving into a strong light (i.e., sun-
light)
● When distance measurement becomes im-
paired due to adhesion of dirt or obstruction
to the sensor
● When a wheel slips
