STANDARD MODE
Allows for optimum driving according to the
driving conditions.
This mode will be selected first each time the
engine is started.
SPORT+ MODE (if so equipped)
In addition to the characteristics of the
SPORT mode, this mode heightens steering
response and changes the setting of VDC
(Vehicle Dynamic Control) for a more sporty
driving experience.
NOTE:
.VDC operation is reduced when the
INFINITI Drive Mode Selector is used
to select the SPORT+ mode. The VDC
system may not operate in the same
circumstances when compared to op-
eration in the standard mode. To help
prevent accidents drive carefully, avoid
careless or dangerous driving techniques
and be especially careful when driving
and cornering on slippery surfaces.
. In the SPORT+ mode, fuel economy may
be reduced.

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 increasing 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.

JVS0934X
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.

erator reaction force under the following
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 system
will not vary the reaction force of the accelerator pedal.
When the INFINITI Drive Mode Selector is
rotated from the ECO mode to another
mode (STANDARD, SPORT+ (if so
equipped), SPORT, SNOW or PERSONAL)
while the ECO pedal system is operating, the
ECO pedal system continues to operate until
the accelerator pedal is released.
If the accelerator pedal is depressed quickly,
the ECO pedal system will not increase the
reaction force of the acceleration pedal. The
ECO pedal system is not designed to prevent
the vehicle from accelerating.
