Hybrid System-8Hybrid System Overview
When the vehicle decelerates while the
vehicle is driven with the shift lever in the D
(drive) position or in the manual shift mode,
the Lithium ion (Li-ion) battery can be
charged by the electric motor. The electric
motor converts the energy of the rotating
wheels into electric power under the follow-
ing circumstances:
.When the accelerator pedal is released.
. When the brake pedal is depressed
. When there is no malfunction in the brake
system or the INFINITI Direct Response
Hybrid
®System
The regenerative brake may not work prop-
erly if the vehicle has tires and road wheels
other than the ones specified in this manual.
Drive your vehicle with smooth acceleration
and deceleration.
. While driving, energy is recovered
through the regenerative brake as the
vehicle decelerates. However, for most
efficient use, do not accelerate or de-
celerate your vehicle more than neces-
sary.
. Avoid abrupt acceleration and decelera-
tion.
. The power of the Lithium ion (Li-ion)
battery can be checked on the Energy
Flow in the center display or Li-ion
battery status meter in the vehicle
information display. See “Energy Flow”
(P.Hybrid System-6) or “Trip computer”
(P.2-28). Gradual or non-abrupt accel-
eration and deceleration will make more
effective use of the electric motor
power, using less gasoline engine power.
. When parking, be sure to place the shift
lever in the P (Park) position. While
driving, place the shift lever in the D
(Drive) position.The Approaching Vehicle Sound for Pedes-
trians (VSP) system is a function that uses
sound to help alert pedestrians of the
presence of the vehicle when it is being
driven at a low speed in the electric drive
mode under the following conditions:
. The sound starts when the vehicle starts
accelerating.
. The sound stops when the vehicle speed
is more than 19 MPH (30 km/h) while
accelerating.
. The sound starts when the vehicle speed
is less than 16 MPH (25 km/h) while
decelerating.
. The sound stops when the vehicle stops.
. The sound does not stop with the vehicle
in the R (Reverse) position even if the
vehicle stops.
The VSP system is automatically turned on
when the vehicle is in the READY to drive
mode.
If there is a malfunction in the VSP system,
the VSP OFF indicator light in the meter
illuminates. See “Approaching Vehicle Sound
for Pedestrians (VSP) OFF indicator light”
(P.2-18).

Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks when the ignition switch is in
the ON position, it may indicate a potential
emission control malfunction.
The malfunction indicator light may also
come on steady if the fuel-filler cap is loose
or missing, or if the vehicle runs out of fuel.
Check to make sure the fuel-filler cap is
installed and closed tightly, and that the
vehicle has at least 3 US gallons (14 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission
control system malfunction exists.
If this indicator light remains on for 20
seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance test.
(See “Readiness for Inspection/Mainte-
nance (I/M) test (US only)” (P.10-19).)
Operation:
The malfunction indicator light will come on
in one of two ways:
. Malfunction indicator light on steady —
An emission control system malfunction
has been detected. Check the fuel-filler
cap if the LOOSE FUEL CAP warning
appears in the vehicle information dis-
play. If the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle. The
