2011 INFINITI QX Owners Manual

The following items are controlled in the
vehicle-to-vehicle distance control mode:
●When there are no vehicles traveling ahead,
the vehicle-to-vehicle distance control mode
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
vehicle-to-vehicle distance control mode ad-
justs the speed to maintain the distance,
selected by driver, from the vehicle ahead.
The adjusting speed range is up to the set
speed. If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill within
the limitations of the system. The system
will cancel once it judges that the vehicle
has come to a standstill with a warning
chime.
● When the vehicle traveling ahead has moved
out from its lane of travel, the vehicle-to-
vehicle distance control mode accelerates
and maintains vehicle speed up to the set
speed. The ICC system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead when approaching toll
gates or traffic congestion.
5-44Starting and driving

The detection zone of the ICC sensor is limited.
A vehicle ahead must be in the detection zone
for the vehicle-to-vehicle distance detection
mode to maintain the selected distance from
the vehicle ahead.
A vehicle ahead may move outside of the de-
tection zone due to its position within the same
lane of travel. Motorcycles may not be detected
in the same lane ahead if they are traveling
offset from the centerline of the lane. A vehicle
that is entering the lane ahead may not be
detected until the vehicle has completely
moved into the lane.If this occurs, the ICC
system may warn you by blinking the system
indicator and sounding the chime. The driver may have to manually control the proper dis-
tance away from vehicle traveling ahead.

Starting and driving5-45

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.

Intelligent Cruise Control (ICC) system
switch
The system is operated by a MAIN switch and
four control switches, all mounted on the steer-
ing wheel.
1. RESUME/ACCELERATE switch:
Resumes set speed or increases speed incre-
mentally.
2. SET/COAST switch:
Sets desired cruise speed, reduces speed
incrementally.
3. CANCEL switch:
Deactivates the system without erasing the
set speed.
4. DISTANCE switch:
Changes the vehicle’s following distance:
● Long
● Middle
● Short
5. MAIN switch:
Master switch to activate the system
Intelligent Cruise Control (ICC) system
display and indicators
The display is located between the speedom-
eter and tachometer.
1. MAIN switch indicator:
Indicates that the MAIN switch is ON.
2. Vehicle ahead detection indicator:
Indicates whether it detects a vehicle in
front of you.
3. Set distance indicator:
Displays the selected distance between ve-
hicles set with the DISTANCE switch.

4. Indicates your vehicle
5. Set vehicle speed indicator:
Indicates the set vehicle speed.
For Canadian models, the speed is displayed
in km/h.
6. Intelligent Cruise Control (ICC) systemwarning light (orange):
The light comes on if there is a malfunction
in the ICC system.
When the ignition switch is pushed to the ON
position, the indicators come on as illustrated
to check for a burned-out bulb, and it turns off
when the engine is started.
Operating vehicle-to-vehicle distance
control mode
To turn on the cruise control,quickly push and
release the MAIN switch
Aon. The MAIN
switch indicator, set distance indicator and set
vehicle speed indicator come on and in a
standby state for setting.

5-48Starting and driving

To set cruising speed,accelerate your vehicle to
the desired speed, push the SET/COAST switch
and release it. (Vehicle ahead detection indica-
tor, set distance indicator and set vehicle speed
indicator come on.) Take your foot off the
accelerator pedal. Your vehicle will maintain the
set speed. When the SET/COAST switch is pushed under
the following conditions, the system cannot be
set and the set vehicle speed indicator will blink
for approximately 2 seconds:
●
When traveling below 20 MPH (32 km/h) and
a vehicle ahead is not detected
● When the selector lever is not in the D or
Manual mode ●
When the windshield wipers are operating at
high speed. The system may cancel when
the wipers are set to the AUTO position.
● When the brakes are operated by the driver
● When the parking brake is applied

When the SET/COAST switch is pushed under
the following conditions, the system cannot be
set.
A warning chime will sound and the set vehicle
speed indicator will blink.
●When the SNOW mode is pushed (SNOW
mode switch) (To use the ICC system, turn off
the SNOW mode switch, push the MAIN
switch to turn off the ICC and reset the ICC
switch by pushing the MAIN switch again.)
For details about the SNOW mode switch,
see “SNOW MODE” later in this section. ●
When the 4WD shift switch is in the 4H or 4L
position. (To use the ICC system, place the
4WD shift switch in the AUTO position, push
the MAIN switch to turn off the ICC system
and reset the ICC switch by pushing the
MAIN switch again (for 4WD models).
For details about the 4WD shift switch, see
“INFINITI ALL-MODE 4WD” earlier in this
section.
● When the VDC system is off (To use the ICC
system, turn on the VDC system. Push the
MAIN switch to turn off the ICC system and
reset the ICC switch by pushing the MAIN
switch again.)
For details about the VDC system, see “VE-
HICLE DYNAMIC CONTROL (VDC) SYSTEM”
later in this section.

control system) is operating
● When driving into a strong light (i.e., sun-
light)
● When a wheel is slipping (To use the ICC
system, make sure the wheels are no longer
slipping. Push the MAIN switch to turn off
the ICC, and reset the ICC system by pushing

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.
