delivered to an INFINITI retailer to
have the Li-ion battery pack and high
voltage parts such as the inverter,
including the wiring harness, re-
moved prior to painting. Li-ion bat-
tery packs exposed to heat in the
paint booth will experience capacity
loss. Damaged Li-ion battery packs
may also pose safety risks to un-
trained mechanics and repair person-
nel.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 Hy-
brid
®System malfunctions
For the above collisions and the certain
hybrid system malfunctions, the READY to
drive indicator light will turn off. See “Warn-
ing lights, indicator lights and audible re-
minders” (P.2-9).
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 READY to
drive position. If this occurs, it is recom-
mended that you contact an INFINITI re-
tailer. Even if the ignition switch is switched
to READY to drive position, the system may
shut-off suddenly. Therefore, drive cau-
tiously to the nearest INFINITI retailer or
contact an INFINITI retailer as soon as
possible. To start the INFINITI Direct Response
Hybrid
®System:
1. Depress the brake pedal and place the ignition switch in the ON position when
the transmission is in the P (Park) or N
(Neutral) position (P is recommended).
(For more details, see “Push-button
ignition switch” (P.5-11).)
2. The READY to drive indicator light
flashes, then turns illuminated. (The
hybrid system switched to the READY
to drive mode when the indicator light
illuminates.)
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 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.

FUEL-FILLER CAP
WARNING
. Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or ser-
iously injured if it is misused or
mishandled. Always stop the
INFINITI Direct Response Hybrid
®
System and do not smoke or allow
open flames or sparks near the ve-
hicle when refueling.
. Do not attempt to top off the fuel
tank after the fuel pump nozzle shuts
off automatically. Continued refuel-
ing may cause fuel overflow, resulting
in fuel spray and possibly a fire.
. Use only an original equipment type
fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in- correct cap can result in a serious
malfunction and possible injury. It
could also cause the Malfunction
Indicator Light (MIL) to come on.
. Never pour fuel into the throttle body
to attempt to start your vehicle.
. Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
— Always place the container on the ground when filling.
— Do not use electronic devices when filling.
— Keep the pump nozzle in contact with the container while you are
filling it.
— Use only approved portable fuel containers for flammable liquid.
CAUTION
. If fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage. .
Failure to tighten the fuel-filler cap
properly may cause the
Malfunc-
tion Indicator Light (MIL) to illumi-
nate. If the
light illuminates
because the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off after a few
driving trips. If thelight does
not turn off after a few driving trips,
have the vehicle inspected. It is
recommended you visit an INFINITI
retailer for this service.
. The Loose Fuel Cap warning will
appear if the fuel-filler cap is not
properly tightened. It may take a few
driving trips for the warning to be
displayed. Failure to tighten the fuel-
filler cap properly after the Loose
Fuel Cap warning appears may cause
the
Malfunction Indicator Light
(MIL) to illuminate.
. For additional information, see “Mal-
function Indicator Light (MIL)” (P.2-
16).
Pre-driving checks and adjustments3-25

.For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any D (Drive) or R (Reverse) position
with the hybrid system running.
Doing so may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious
vehicle damage or personal injury.
. Do not attempt to test an AWD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing), or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that
your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.
. When a wheel is off the ground due
to an unlevel surface, do not spin the
wheel excessively.WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The INFINITI Direct
Response Hybrid
®System will stop
when the ignition switch is pushed 3
consecutive times or the ignition switch
is pushed and held for more than 2
seconds.) If the hybrid system turns off
while the vehicle is being driven, this
could lead to a crash and serious injury.
