5-22Starting and driving
SPORT MODE
Adjusts the engine and transmission
points for a higher response. The setting
of the steering system is adjusted to
provide a quick steering response and a
heavy steering effort.
NOTE:
In the SPORT mode, fuel economy may be
reduced.
SNOW MODE
Changes the engine characteristics to aid
driving on slippery roads.
ECO MODE
Assists the driver’s eco-driving. The engine
and transmission points are adjusted for
improved fuel economy, providing such a
driving features as smooth starting or
constant cruising.
NOTE:
Selecting the ECO mode will not necessa-
rily improve fuel economy as many driving
factors influence its effectiveness.
Operation
Select the ECO mode using the INFINITI
Drive Mode Selector. The ECO drive indi-
cator light on the instrument panel illumi-nates.
When the accelerator pedal is depressed
within the range of economy drive, the ECO
drive indicator light illuminates in green.
When the accelerator pedal is depressed
above the range of economy drive, the ECO
drive indicator light turns off. For ECO
pedal system equipped models, see
“ECO
pedal system” (P.5-22).
The ECO drive indicator light will not
illuminate in the following cases:
. When the shift lever is in the R (Reverse)
position.
. When the vehicle speed is below 2 MPH
(3.2 km/h) or over 90 MPH (144 km/h).
. When the cruise control (if so equipped)
or the Intelligent Cruise Control (ICC)
system (if so equipped) is operated.
ECO pedal system (if so equipped)
The ECO pedal system helps assist the
driver to improve fuel economy by increas-
ing the reaction force of the accelerator
pedal. When the ECO drive indicator light is
blinking or remains off, the ECO pedal
system increases the reaction force of the
accelerator pedal.
JVS0303X
When the ECO drive indicator illuminates in
green, the accelerator reaction force is
normal. When the ECO drive indicator light
is blinking or remains off, the ECO pedal
system increases the reaction force of the
accelerator pedal.
The ECO pedal system may not vary
accelerator reaction force under the follow-
ing conditions:
. When the shift lever is in the N (Neutral)
or R (Reverse) position.
. When Intelligent Cruise Control (ICC) is
being operated.
If the ECO pedal system malfunctions, it
will cancel automatically. The ECO pedal

5-36Starting and driving
Automatic deactivation
Condition A:
The warning and assist functions of the
LDP system are not designed to work under
the following conditions:
.When you operate the lane change
signal and change the traveling lanes
in the direction of the signal. (The LDP
system will be deactivated for approxi-
mately 2 seconds after the lane change
signal is turned off.)
. When the vehicle speed lowers to less
than approximately 45 MPH (70 km/h).
. When the BSI system activates an
audible warning or steering control.
After the above conditions have finished
and the necessary operating conditions are
satisfied, the warning and assist functions
will resume.
Condition B:
The assist function of the LDP system is not
designed to work under the following
conditions (warning is still functional):
. When the steering wheel is turned as
far as necessary for the vehicle to
change lanes. .
When the accelerator pedal is de-
pressed while the steering control
assist is provided.
. When the Intelligent Cruise Control (ICC)
approach warning occurs.
. When the hazard warning flashers are
operated.
. When driving on a curve at high speed.
After the above conditions have finished
and the necessary operating conditions are
satisfied, the LDP steering control assist
function will resume.
Condition C:
Under the following conditions, a beep will
sound and the LDP system will be canceled
automatically. The “LDP currently unavail-
able” message will appear in the vehicle
information display, and the LDP system
cannot be activated:
. When the VDC system (except TCS
function) or ABS operates.
. When the VDC system is turned off.
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode.
Action to take:
When the above conditions no longer exist,
push the dynamic driver assistance switch
again to turn the LDP system back on. Temporary disabled status at high tem-
perature:
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 1048F (408C)) and then the
LDP system is turned on, the LDP system
may be deactivated automatically. The
“ high cabin temperature” message will
appear in the vehicle information display.
Action to take:
When the above conditions no longer exist,
push the dynamic driver assistance switch
again to turn the LDP system back on.
LANE CAMERA UNIT MAINTENANCE
The LDW/LDP system uses the same lane
camera unit that is used by Active Lane
Control, located above the inside mirror.
For maintenance of the camera, see “Lane
camera unit maintenance ”(P.5-29).

5-56Starting and driving
PRECAUTIONS ON CRUISE CONTROL
.If the cruise control system malfunc-
tions, it will cancel automatically. The
cruise indicator (green) in the vehicle
information display will then blink to
warn the driver.
. If the engine coolant temperature be-
comes excessively high, the cruise
control system will be canceled auto-
matically.
. If the cruise indicator (green) blinks,
turn the cruise control MAIN switch off
and have the system checked by your
INFINITI retailer.
. The cruise indicator (green) may some-
times blink when the cruise control
MAIN switch is turned ON while push-
ing the SET/COAST (-), RESUME/ACCEL-
ERATE (+) or CANCEL switch. To properly
set the cruise control system, perform
the steps below in the order indicated.
WARNING
Do not use the cruise control when driving
under the following conditions:
. when it is not possible to keep the
vehicle at 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
control and result in an accident.
