2010 INFINITI QX Owners Manual

●The system may not detect the vehicle
in front of you in certain road or weather
conditions. To avoid accidents, never
use the Intelligent Cruise Control sys-
tem under the following conditions:
– On roads where the traffic is heavy or there are sharp curves.
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.) (When the windshield wiper is
operated at the low speed (LO) or
high speed (HI) position, the Intelli-
gent Cruise Control system is auto-
matically canceled.)
– When strong light (for example, at sunrise or sunset) is directly shining
on the front of the vehicle.
– When rain, snow or dirt adhere to the system sensor.
– On steep downhill roads (the vehicle may go beyond the set vehicle speed
and frequent barking may result in
overheating the brakes) .
– On repeated uphill and downhill roads. – When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration.
● Do not use the Intelligent Cruise Con-
trol system if you are towing a trailer.
The system may not detect a vehicle
ahead.
● In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. You may
need to control the distance from other
vehicles using the accelerator pedal. Al-
ways stay alert and avoid using the ICC
system when it is not recommended in
this section.
Vehicle-to-vehicle distance mode
operation
Always pay attention to the operation of the ve-
hicle and be ready to manually control the proper
following distance. The Intelligent Cruise Control
(ICC) system may not be able to maintain the
selected distance between vehicles (following
distance) or selected vehicle speed under some
circumstances.
The vehicle-to-vehicle distance control mode
uses a sensor
1located on the front of the
vehicle to detect vehicles ahead. The sensor
generally detects the signals returned from the
reflectors on a vehicle ahead. Therefore, if the

sensor cannot detect the reflector of the vehicle
ahead, the ICC system may not maintain the
selected distance.
The following are some conditions in which the
sensor cannot detect the signals:● When the reflector is positioned high on the
vehicle (trailer, etc.) .
● When the reflector on the vehicle ahead is
missing, damaged or covered.
● When the reflector is covered with dirt, snow
and road spray.
● When the snow or road spray from other
vehicles reduces the sensor’s visibility.
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility.
● When excessively heavy baggage is loaded
in the rear seat or the cargo area of your
vehicle.
● When your vehicle is towing a trailer, etc.
The ICC system is designed to automatically
check the sensor’s operation. When the sensor is
covered with dirt or obstructions, the system will
automatically be canceled while allowing con-
ventional cruise control to remain operational. If
the sensor is covered with ice, a transparent or translucent vinyl bag, etc., the ICC system may
not detect them. In these instances, the vehicle-
to-vehicle distance control mode may not cancel
and may not be able to maintain the selected
following distance from the vehicle ahead. Be
sure to clean the sensor regularly.
The vehicle-to-vehicle distance control mode is
designed to maintain a selected distance and
reduce the speed to match the speed of a slower
vehicle ahead; the system decelerates the ve-
hicle as necessary. However, the ICC system can
only apply up to 25% of the vehicle’s total braking
power. This system should only be used when
traffic conditions allow vehicle speeds to remain
fairly constant or vehicle speeds change gradu-
ally. If a vehicle moves into the traveling lane
ahead or if a vehicle traveling ahead rapidly de-
celerates, the distance between vehicles may
become closer because the ICC system cannot
decelerate the vehicle quickly enough. If this oc-
curs, the ICC system will sound a warning chime
and blink the system display to notify the driver to
take necessary action.
The system will cancel and a warning chime will
sound if the speed falls below approximately 20
MPH (32km/h) . The system will also disengage
below the 20 MPH (32km/h) cut-off speed or
over the maximum set speed.
Refer to “Approach warning” later in this section.The following items are controlled when the se-
lector lever is in any D (Drive) position.
● 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 approxi-
mately 25 and 89 MPH (40 and 144 km/h) .
● When there is a vehicle traveling ahead, the
vehicle-to-vehicle distance control mode
adjusts the speed to maintain the distance
selected by the driver from the vehicle
ahead. The adjusting speed range is be-
tween approximately 20 MPH (32 km/h) and
the set speed.
● When the vehicle traveling ahead has moved
out from its lane of travel, the vehicle-to-
vehicle distance control mode accelerates
and maintains 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.

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 detec-
tion 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 enter-
ing the lane ahead may not be detected until the
vehicle has completely moved in 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 distance away from ve-
hicle traveling ahead.

When driving on some roads, such as winding,
hilly, curved, narrow, 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 accelerate the vehicle.
The detection of vehicles can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or vehicle condition.If this
occurs, the ICC system may warn you by
blinking the system indicator and sounding
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 will adjust the speed to maintain the dis-
tance, 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 con-
trol 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 happens, drive with-
out the ICC system.

System operation
WARNING
Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle
according to the speed of the vehicle
ahead. Depress the accelerator to prop-
erly accelerate your vehicle when accel-
eration is required for a lane change. De-
press the brake pedal when deceleration
is required to maintain a safe distance to
the vehicle ahead due to its sudden brak-
ing or if a vehicle cuts in. Always stay alert
when using the 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. The
CRUISE indicator light in the vehicle information
display comes on.
Vehicle detected ahead:
When a vehicle is detected in the lane ahead, the
ICC system decelerates the vehicle by control-
ling 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 a driver
selected distance.
The stoplights of the vehicle come on and
the brake pedal depresses when braking is
performed by the ICC system.
CAUTION
Never place your foot under the brake
pedal, when the brake is operated by the
Intelligent Cruise Control system. You
may get your foot caught in the pedal.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and se-
lected 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 the vehicle.
