Active Engine Brake:
“Active Engine Brake” can be set to ON (en-
abled) or OFF (disabled). For additional infor-
mation, see “Active Engine Brake” (P. 5-157 ).
Reset Drive Mode Settings to Default:
Select “Reset Drive Mode Settings to De-
fault” and select “OK” to restore all the PER-
SONAL mode settings to default.
ECO MODE
The ECO mode adjusts the engine and trans-
mission to enhance fuel economy.
NOTE:
Selecting this drive mode will not necessarily
improve fuel economy as many driving fac-
tors influence its effectiveness.
Operation
Push the Drive Mode Selector switch to the
ECO position. “ECO” appears in the vehicle
information display and the ECO drive indi-
cator light illuminates on the instrument
panel. ECO mode will also be displayed in the
upper display.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. 5-30).
The ECO drive indicator light will not illumi-
nate in the following cases:
• When the shift lever is in the R (Reverse)
position.
• When the vehicle speed is below 3 mph (4.8 km/h) or over 90 mph (144 km/h).
• When the Intelligent Cruise Control 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 increasing the
reaction force of the accelerator pedal. When
the ECO drive indicator light is blinking or
turns off, the ECO pedal system increases
the reaction force of the accelerator pedal.

When the ECO drive indicator light illumi-
nates in green, the accelerator reaction force
is normal. When the ECO drive indicator light
is blinking or turns off, the ECO pedal system
increases the reaction force of the accelera-
tor pedal.
The ECO pedal system may not vary accel-
erator reaction force under the following
conditions:
• When the shift lever is in the N (Neutral) or R (Reverse) position.
• When Intelligent Cruise Control (if so equipped) is being operated.

following conditions as it may not func-
tion properly:
– During bad weather (rain, fog, snow,
etc.).
– When driving on slippery roads, such
as on ice or snow.
– When driving on winding or uneven
roads.
– When there is a lane closure due to
road repairs.
– When driving in a makeshift or tem-
porary lane.
– When driving on roads where the lane
width is too narrow.
– When driving without normal tire
conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, nonstandard
wheels).
– When the vehicle is equipped with
non-original brake parts or suspen-
sion parts.
– When you are towing a trailer or
other vehicle. The system may not function properly under
the following conditions:
• On roads where there are multiple parallel
lane markers; lane markers that are faded
or not painted clearly; yellow painted lane
markers; non-standard lane markers; or
lane markers covered with water, dirt,
snow, etc.
• On roads where the discontinued lane markers are still detectable.
• On roads where there are sharp curves.
• On roads where there are sharply contrast- ing objects, such as shadows, snow, water,
wheel ruts, seams or lines remaining after
road repairs. (The LDW system could de-
tect these items as lane markers.)
• On roads where the traveling lane merges or separates.
• When the vehicle’s traveling direction does not align with the lane marker.
• When traveling close to the vehicle in front of you, which obstructs the lane camera
unit detection range.
• When rain, snow, dirt or an object adheres to the windshield in front of the lane cam-
era unit.
• When the headlights are not bright due to dirt on the lens or if the aiming is not ad-
justed properly. • When strong light enters the lane camera
unit. (For example, the light directly shines
on the front of the vehicle at sunrise or
sunset.)
• When a sudden change in brightness oc- curs. (For example, when the vehicle enters
or exits a tunnel or under a bridge.)
SYSTEM TEMPORARILY
UNAVAILABLE
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 automati-
cally and the following message will appear in
the vehicle information display: “Not avail-
able: High Camera Temp.”
When the interior temperature is reduced, the
LDW system will resume operating
automatically.
The LDW system is not designed to warn
under the following conditions:
• When you operate the lane change signaland change traveling lanes in the direction
of the signal. (The LDW system will become
operable again approximately 2 seconds
after the lane change signal is turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
5-38Starting and driving

After the above conditions have finished and
the necessary operating conditions are satis-
fied, the LDW functions will resume.
SYSTEM MALFUNCTION
If the LDW system malfunctions, it will cancel
automatically and “Malfunction” will appear
in the vehicle information display. If “Mal-
function” appears in vehicle information dis-
play, pull off the road to a safe location and
stop the vehicle. Place the shift lever in the P
(Park) position and ignition switch in the OFF
position and restart the engine. If “Malfunc-
tion” continues to appear in vehicle informa-
tion display, have the system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
SYSTEM MAINTENANCE
The lane camera unitO1for the LDW system
is located above the inside mirror. To keep the
proper operation of the LDW system and
prevent a system malfunction, be sure to ob-
serve the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar- ent material) or install an accessory near
the camera unit. • Do not place reflective materials, such as
white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers.

change lanes without first activating
your turn signal or, for example, if a con-
struction zone directs traffic to cross an
existing lane marker. If this occurs you
may need to apply corrective steering to
complete your lane change.
• Because the LDP may not activate under
the road, weather, and lane marker con-
ditions described in this section, it may
not activate every time your vehicle be-
gins to leave its lane and you will need to
apply corrective steering.
• The LDP system will not operate at
speeds below approximately 37 mph (60
km/h) or if it cannot detect lane markers.
