●In the event of an accident that requires
body repair and painting, the vehicle
should be delivered to an INFINITI re-
tailer to have the Li-ion battery pack
and high-voltage parts such as the in-
verter, including the wiring harness, re-
moved prior to painting. Li-ion battery
packs exposed to heat in the paint
booth will experience capacity loss.
Damaged Li-ion battery packs may also
pose safety risks to untrained mechan-
ics and repair personnel. The emergency shut-off system is activated and
the high-voltage system automatically turns off in
the following conditions:
● Front and side collisions in which the air
bags are deployed
● Certain rear collisions
● Certain INFINITI Direct Response Hybrid
System malfunctions
For the above collisions and the certain hybrid
system malfunctions, the READY to drive indica-
tor light will turn off. For additional information,
refer to “Warning lights, indicator lights and au-
dible reminders” in the “Instruments and con-
trols” section of this manual.
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 switch to the READY to drive position; it is
recommended that you contact an INFINITI re-
tailer. Even if the ignition switch is switched to the
READY to drive position, the system may shut off
suddenly. Therefore, drive cautiously to the near-
est INFINITI retailer or contact an INFINITI retailer
as soon as possible. To start the INFINITI Direct Response Hybrid
System, depress the brake pedal and place the
ignition switch in the ON position when the trans-
mission is in the P (Park) position or N (Neutral)
position (P is recommended) .
CAUTION
Do not start the system in N (Neutral)
position under cold condition of the sys-
tem. Start in the P (Park) position in that
case.
The READY to drive indicator light
flashes
until the hybrid system is ready to drive.
If starting in a low temperature environment, the
flashing time of the READY lamp becomes lon-
ger. It cannot move out from P (Park) during
flashing.
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 auto-
matically. It may stop during deceleration
or when the vehicle is stopped.
