●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, it is
recommended that you visit 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 their electromagnetic shield-
ings.
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.
