2011 INFINITI EX ECO mode

LDW system operation
The LDW system provides a lane departure
warning function when the vehicle is driven at
speeds of approximately 45 MPH (70 km/h) and
above. When the vehicle approaches either the
left or the right side of the traveling lane, a
warning chime will sound and the lane depar-
ture warning light (orange) on the instrument
panel will blink to alert the driver.
The warning function will stop when the vehicle
returns inside of the lane markers.
When you operate the lane change signal and
change traveling lanes in the direction of the
signal, the LDW system temporarily suspends
operation. It will become operable again ap-
proximately 2 seconds after the lane change
signal is turned off.
When the vehicle speed lowers to less than
approximately 45 MPH (70 km/h), the LDW
system will not provide a warning.
The LDW system has an automatic setting mode
and a manual setting mode. The setting mode
can be changed. In the automatic setting mode,
the LDW system is automatically turned on
when the ignition switch is pushed to the ON
position. When the LDW system is on, the
warning systems ON indicator
1on the warn-
ing systems switch illuminates. To cancel the LDW system, push the warning systems switch.
The warning systems ON indicator will turn off.
To turn on the system, push the warning sys-
tems switch again. This switch will turn on and
off the LDW, BSW and FCW systems at the same
time.
In the manual setting mode, you need to push
the warning systems switch to turn on the
system after the ignition switch is pushed to the
ON position.
The setting mode can be changed using the
warning systems switch. To change the setting
mode, push and hold the warning systems
switch for more than 4 seconds when the
warning systems ON indicator is off. When the
mode is changed, a chime sounds and the lane
departure warning light (orange) flashes.
Temporary disabled status at high
temperature
If the vehicle is parked in direct sunlight under
high temperature conditions (over approxi-
mately 104°F (40°C) and then started, the LDW
system may be deactivated automatically. The
lane departure warning light (orange) on the
switch will flash.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control mode,
the Intelligent Cruise Control (ICC) system auto-
matically maintains a selected distance from
the vehicle traveling in front of you according to
that vehicle’s speed (up to the set speed), or at
the set speed when the road ahead is clear.
With ICC, the driver can maintain the same
speed as other vehicles without the constant
need to adjust the set speed as you would with
a normal cruise control system.

– During bad weather (rain, fog, snow, etc.)When the windshield wiper is operated at
the low speed (LO) or high speed (HI) po-
sition, the Intelligent Cruise Control sys-
tem is automatically canceled.
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys- tem sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed and fre-
quent braking may result in overheating
the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it difficult to keep a proper distance between vehicles
because of frequent acceleration or
deceleration
● Do not use the Intelligent Cruise Control sys-
tem 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 dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the ICC system when it is not recommended
in this section.
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of the
vehicle and be ready to manually control the
proper following distance. The vehicle-to-
vehicle distance control mode of the Intelligent
Cruise Control (ICC) system may not be able to
maintain the selected distance between ve-
hicles (following distance) or selected vehicle
speed under some circumstances.
The vehicle-to-vehicle distance control mode
uses a sensor
Alocated on the front of the
vehicle to detect vehicles traveling ahead. The
sensor generally detects the signals returned
from the reflectors on a vehicle ahead. There-
SSD0701
Starting and driving5-37

fore, if the sensor cannot detect the reflector on
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 of the vehicle ahead is
positioned high on the vehicle (trailer, etc.)
● When the reflector on the vehicle ahead is
missing, damaged or covered
● When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
● When the snow or road spray from traveling
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 luggage room of your
vehicle
The ICC system is designed to automatically
check the sensor’s operation within the limita-
tion of the system. When the sensor is covered
with dirt or is obstructed, the system will auto-
matically be canceled. 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 check and
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 slower vehicle
ahead. The system will decelerate the vehicle as
necessary and if the vehicle ahead comes to a
stop, the vehicle decelerates to a standstill.
However, the ICC system can only apply up to
25% of the vehicles total braking power. This
system should only be used when traffic condi-
tions allow vehicle speeds to remain fairly
constant or when vehicle speeds change gradu-
ally. If a vehicle moves into the traveling lane
ahead or if a vehicle traveling ahead rapidly
decelerates, the distance between vehicles may
become closer because the ICC system cannot
decelerate the vehicle quickly enough. If this
occurs, 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 is below approximately 15
MPH (24 km/h) and a vehicle is not detected
ahead. The system will also disengage when
the vehicle goes above the maximum set speed.
See “Approach warning” later in this section.
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 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.

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 ahead is not detected and
your vehicle is traveling below the speed of
15 MPH (24 km/h)
● When the system judges the vehicle is at
standstill
● When the selector lever is not in the D, DS or
Manual mode
● When the windshield wipers are operating at
low (LO) or high speed (HI). If the vehicle is
equipped with a rain sensing auto-wiper, the
system may cancel when the wipers are set
to intermittent (INT).
● When the parking brake is applied
● When the SNOW mode switch is turned ON
● When the VDC system is turned off
● When ABS or VDC (including the traction
control system) operates ●
