The hybrid system uses high voltage up to ap-
proximately 144 volts. High-voltage components
are indicated in the illustration. High-voltage har-
nesses are orange. The system can be hot during
and after starting. Be careful of both the high
voltage and the high temperature.

HYBRID VEHICLE
CHARACTERISTICS
WARNING
●When you leave your vehicle, be sure to
place the ignition switch in the OFF
position.
● Be sure to put the transmission in the P
(Park) position because the vehicle can
move when the READY to drive indica-
tor light is on even if the gasoline en-
gine is not running. When the READY to
drive indicator light is on, do not leave
your vehicle in a shift position other
than the P (Park) position. The vehicle
will creep and start abruptly if the accel-
erator pedal is depressed by mistake.
This may cause serious injury or death.
CAUTION
●If the vehicle is parked for a long period
of time, the battery discharges gradu-
ally. To avoid this occurrence, drive the
vehicle for approximately 30 minutes at
least once every two to three months.
Otherwise, the Lithium ion (Li-ion) bat-
tery may be damaged. If the Li-ion bat-
tery is completely discharged and the
hybrid system cannot be activated, con-
tact an INFINITI retailer.
High-voltage parts and harnesses on the hybrid
vehicles emit approximately the same amount of
electromagnetic waves as the conventional
gasoline-powered vehicles or home electronic
appliances despite of their electromagnetic
shieldings.
Charging the Li-ion battery while driving is impor-
tant. The vehicle cannot run if the Li-ion battery is
discharged. In the N (Neutral) position, the Li-ion
battery does not recharge. Leaving the transmis-
sion in the N (Neutral) position for an extended
period of time may discharge the Li-ion battery.
The Li-ion battery recharges when the shift lever
is in any position other than N (Neutral) . An air vent is located on the rear side trim panels
Ato cool the high-voltage battery. If the vent is
covered, the battery will overheat resulting in
reduced output performance of the hybrid sys-
tem. For additional information, refer to “Lithium-
ion (Li-ion) battery air vent” in the “Appearance
and care” section of this manual.
You may hear the noise of the cooling fan from the
air vent.
CAUTION
Do not place objects over or into the air
vent. The Li-ion battery or DC/DC con-
verter may overheat and be damaged.

CAUTION
Do not load large amounts of water in
open containers (aquariums or buckets)
into the vehicle. If the water spills onto the
Li-ion battery, it may cause a short circuit
and damage the battery.
CAUTION
It may cause a short circuit and damage
the Li-ion battery or DC/DC converter.
Noise and vibration
After the hybrid system is activated, the following
noises and vibrations that are unique to the hy-
brid system may occur. This does not indicate a
malfunction.● Electric motor noise from the engine com-
partment
● Noise from the rear of the vehicle when the
hybrid system activates or deactivates
● Noise and vibration when the gasoline en-
gine starts running or stops
● Operating noise or electric motor noise
when releasing the accelerator pedal or de-
pressing the brake pedal
● Engine noise due to rapid acceleration ●
Fan noise from the air inlet located on the
rear parcel shelf
● Noise from the climate control system
● Noise from the vehicle in order to alert pe-
destrians to the presence of an approaching
vehicle. For additional information, refer to
“Approaching Vehicle Sound for Pedestri-
ans (VSP) system” in this section.

FRONT POWER SEAT ADJUSTMENT
Operating tips
●The power seat motor has an auto-reset
overload protection circuit. If the motor
stops during operation, wait 30 seconds,
then reactivate the switch.
● Do not operate the power seat switch for a
long period of time when the INFINITI Direct
Response Hybrid® System is not running.
This will discharge the 12–volt battery. For additional information, refer to “Automatic
drive positioner” in the “Pre-driving checks and
adjustments” section of this manual for automatic
drive positioner operation.
Forward and backward
Moving the switch forward or backward will slide
the seat forward or backward to the desired
position.
Reclining
Move the recline switch backward until the de-
sired angle is obtained. To bring the seatback
forward again, move the switch forward and
move your body forward. The seatback will move
forward.
The reclining feature allows adjustment of the
seatback for occupants of different sizes for
added comfort and to help obtain proper seat
belt fit. For additional information, refer to “Pre-
cautions on seat belt usage” in this section. Also,
the seatback can be reclined to allow occupants
to rest when the vehicle is stopped and the shift
lever is in P (Park) .

ASSIST CHARGE GAUGE
The Assist Charge Gauge indicates the condition
of the electric motor. When the needle is be-
tween the center and “charge” (
1range) , this
indicates that the electric motor is generating
power to recharge the Li-ion battery.
When the needle is between the center and the
PWR side, this indicates that the electric motor is
powering the drive wheels and the Li-ion battery
is discharging.
