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. See “Warning/indicator
lights and audible reminders” in the “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 switch 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. 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) .
The READY to drive indicator light
flashes
until hybrid system becomes the ready to drive
mode.
If starting in low temperature environment, flash-
ing time of READY lamp becomes longer. It can-
not move out from P range 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.
The gasoline engine may automatically run in the
following conditions:
● The level of remaining charge in the Li-ion
battery is low. The engine runs to charge the
Li-ion battery and to provide power to drive
the vehicle.
● The temperature of the engine coolant is
low. ●
When A/C is used.
● When opening door.
● When engine hood is opened.
● When applying brakes.
● Based on driving conditions.
● The shift 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.
Engine is hard to stop during these driving con-
ditions: ● Outside temperature is high/low and A/C is
on.
● When repeatedly starting and stopping the
engine.
STARTING AND SLOW SPEED
DRIVING
In some cases, the vehicle can be driven by
electric motor during extremely slow speed
creep, but the engine starts when accelerating or
taking off the brakes.

EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with“*”isfound later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hoodCheck that the doors
and engine hood operate properly. Also ensure
that all latches lock securely. Lubricate hinges,
latches, latch pins, rollers and links as necessary.
Make sure that the secondary latch keeps the
hood from opening when the primary latch is
released.
When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights* Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)* When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary. Tire rotation*
Tires should be rotated every
5,000 miles (8,000 km).
Tires* Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, adjust the pressure in all tires, including the
spare, to the pressure specified. Check carefully
for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Wheel alignment and balance If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for wheel
alignment. If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing may be
needed.
● For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility. Windshield wiper blades*
Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the ve-
hicle, etc.
Additional information on the following
items with an “*” is found later in this sec-
tion.
Accelerator pedal Check the pedal for smooth
operation and make sure the pedal does not bind
or require uneven effort. Keep the floor mat away
from the pedal.
Brake pedal Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down fur-
ther than normal, the pedal feels spongy or the
vehicle seems to take longer to stop, see an
INFINITI retailer immediately. Keep the floor mat
away from the pedal.
Brakes Check that the brakes do not pull the
vehicle to one side when applied.
Continuously Variable Transmission (CVT)
P (Park) position mechanism On a fairly
steep hill check that your vehicle is held securely
with the shift lever in the P (Park) position without
applying any brakes.
