drive indicator light will turn off. See
“ Warning/indicator lights and audible re-
minders ”in the “2. Instruments and
controls ”.
The emergency shut-off activates for the
above collisions to minimize risk of an
event that could cause injury or an
accident. If the emergency shut-off system
activates, the hybrid system may not
switched to READY to drive position,
contact an INFINITI retailer. Even if the
ignition switch is switched to READY to
drive position, the system may shut-off
suddenly. Therefore, drive cautiously to the
nearest INFINITI retailer or contact an
INFINITI retailer as soon as possible. Depress the brake pedal and place the
ignition switch in the ON position when the
transmission is in the P (Park) position or N
(Neutral) position (P is recommended) to
start the INFINITI Direct Response Hybrid
TM
System.
The READY to drive indicator light
flashes until hybrid system becomes the
ready to drive mode.
When the READY to drive indicator light
illuminates, the vehicle can be
driven, even if the gasoline engine is not
running.
NOTE:
The gasoline engine starts and stops
automatically. It may stop during low
speed driving, deceleration or when the
vehicle is stopped.
The gasoline engine may automatically
run in the following conditions:
. The level of remaining charge in the
Lithium ion (Li-ion) battery is low. The
engine runs to charge the Li-ion battery
and to provide power to the drive the
vehicle.
. The temperature of the engine coolant
is low. .
Based on driving conditions.
. The selector lever is shifted to the P
(Park) position, the driver ’s seat belt is
released and the driver ’s side door is
then opened.
The hybrid system operates as follows
based on driving conditions and the Li-ion
battery charge.STARTING AND SLOW SPEED DRIV-
ING
The vehicle is driven by the electric motor
depending on the available Li-ion battery
charge.
MEDIUM OR HIGH SPEED DRIVING
The system automatically controls the
gasoline engine and electric motor in order
to obtain the optimum fuel mileage and
performance, depending on the driving
situation and available Li-ion battery
charge.
When the remaining battery level is low,
the Li-ion battery is charged by the electric
motor that is driven to generate electric
power while the vehicle is driving.
