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 NISSAN PUREDRIVE™ Hybrid Sys-
tem 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 a
NISSAN dealer. Even if the ignition switch is
switched to READY to drive position, the system
may shut off suddenly. Therefore, drive cautiously
to the nearest NISSAN dealer or contact a
NISSAN dealer as soon as possible. To start the NISSAN PUREDRIVE™ Hybrid Sys-
tem, depress the brake pedal and place the igni-
tion switch in the ON position when the transmis-
sion 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 L (Low) position is engaged and Over
Drive is off.
● 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.
EMERGENCY SHUT-OFF SYSTEM OPERATION OF THE HYBRID SYSTEM
HEV-4HEV Overview

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, depend-
ing 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 ve-
hicle is driving.
RAPID ACCELERATION
The vehicle is accelerated using both the gaso-
line engine and the electric motor depending on
the available Li-ion battery charge.
DECELERATION AND BRAKING
The Li-ion battery is charged by the electric mo-
tor that changes the energy of the rotating
wheels into electric power. See “Regenerative
brake” later in this section.
STOPPING
The gasoline engine may stop running to save
fuel depending on the available Li-ion battery
charge.The NISSAN Direct Response Hybrid™ System
monitors the status of power being sent to the
electric motor and the Li-ion battery state of
charge. The status is shown on the assist charge
gauge in the meter and the energy
flow/remaining Li-ion battery charge in the dot
matrix display. System status can also be shown
on the navigation system display (if so equipped)
when the screen is in the energy flow mode or
energy/fuel history mode.
POWER METER
This meter displays the actual electric motor
power consumption and the charging power to
the Li-ion battery.
For additional information, See “Power meter” in
the “Instruments and controls” section.

POSITIONS BEFORE STARTING THE NISSAN
PUREDRIVE™ HYBRID SYSTEM
Starting and driving5-3

3.Use Air Conditioning (A/C) at Higher
Vehicle Speeds
● Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load
● Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the vehicle
due to increased aerodynamic drag
● Recirculating the cool air in the cabin
when the A/C is on reduces cooling load
● Turn off air conditioning when it is not
necessary
4. Drive at Economical Speeds and Dis-
tances
● Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where le-
gally allowed) can improve fuel efficiency
due to reduced aerodynamic drag
● Maintaining a safe following distance be-
hind other vehicles reduces unnecessary
braking
● Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes
● Select a gear range suitable to road con-
ditions
● Frequent short-distance driving can re-
duce fuel economy 5.
Use Cruise Control
● Using cruise control during highway driv-
ing helps maintain a steady speed
● Cruise control is particularly effective in
providing fuel savings when driving on flat
terrains
6. Plan for the Shortest Route
● Utilize a map or navigation system to de-
termine the best route to save time
7. Avoid Idling
● Shutting off your engine when safe for
stops exceeding 30–60 seconds saves
fuel and reduces emissions
8. Buy an Automated Pass for Toll Roads
● Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting
9. Winter Warm Up
● Limit idling time to minimize impact to fuel
economy
●
Vehicles typically need no more than
30 seconds of idling at start-up to effec-
tively circulate the engine oil before driving
● Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling
● Park your vehicle in moderate ambient
temperatures when possible
10. Keeping your Vehicle Cool
● Park your vehicle in a covered parking
area or in the shade whenever possible
● When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system
11. Cargo
● Avoid transporting unnecessary luggage
in the vehicle
● Avoid carrying luggage in the roof rack
which can increase aerodynamic drag
12. Break-in
● Your vehicle may need a break-in period
for more than 4000 miles to improve the
fuel economy
● Avoid measuring fuel economy within ini-
tial 1200 miles
Starting and driving5-5

13.Use D (Drive)
● Use the D (Drive) and drive with the Over
Drive on as much as possible
● Driving with the Over Drive OFF or in the
L (Low) position may cause the engine to
run longer than necessary and reduce
fuel economy
This system uses microphones
1located inside
the vehicle to detect engine booming sound. The
system then automatically produces a muted en-
gine booming sound through the speakers and
woofer (if so equipped) to reduce engine boom-
ing sound.
NOTE:
To operate the active noise control system
properly:
● Do not cover the speakers or woofer (if so
equipped) .
● Do not cover the microphones.

●Do not change or modify speakers including
the woofer and any audio related compo-
nents such as the amplifier.
● Do not make any modification including
sound deadening or modifications around
the microphones or speakers.WARNING
Your brake system may not be working
properly if the hydraulic brake warning
light and the electronically controlled
brake system warning light is on. Driving
could be dangerous. If you judge it to be
safe, drive carefully to the nearest service
station for repairs. Otherwise, have your
vehicle towed because driving it could be
dangerous.
BRAKE PRECAUTIONS
Vacuum-assisted brakes
The brake booster aids braking by using engine
vacuum. If the hybrid system is turned off, you can
stop the vehicle by depressing the brake pedal.
However, greater foot pressure on the brake
pedal will be required to stop the vehicle and
stopping distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage. To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
When applying the brakes, you may hear a sound
coming from the braking system. This is normal.
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or acceler-
ating could cause the wheels to skid and
result in an accident.
