c. You notice a change in the sound ofthe exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
● Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
CAUTION
● Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants. ●
Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label, located in the
driver’s door opening. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check all 4 tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-

correct direction when inserting it to
the Intelligent Key port. The engine may
not start if it is in the wrong direction.
● Remove the Intelligent Key from the
Intelligent Key port after the ignition
switch is pushed to the LOCK position.
NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer system will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using a registered key
(for example, when interference is caused by
another registered key, an automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedure:
1. Leave the ignition switch in the ON position for approximately 5 seconds.

Starting and driving5-9

2. Place the ignition switch in the OFF orLOCK position, and wait approximately 10
seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake fluid, and windshield–washer fluid
as frequently as possible, or at least when-
ever you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Lock all doors.
● Position seat and adjust head restraints.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is pushed to the ON
position. See “Warning/indicator lights and
audible reminders” in the “Instruments and
controls” section of this manual. 1. Apply the parking brake.
2. Move the shift selector to P (Park) .
The Hybrid System is designed not to
operate if the shift selector is not in the
P (Park) position.
3. Place the ignition switch in the ON position. Depress the brake pedal and push the igni-
tion switch to start the Hybrid System. The
READY light will illuminate on the meter.
NOTE:
When starting the Hybrid System at very
low outside temperatures, the READY light
will flash and it may take longer for the
READY light to illuminate. ●The engine may not start even with the
READY light illuminated. Once the
READY light is illuminated you may begin
driving the vehicle.
● You may hear a sound in the engine com-
partment when the brake pedal is de-
pressed with the Hybrid System off. This
does not indicate a problem.

CONTINUOUSLY VARIABLE
TRANSMISSION (eCVT)
WARNING
●Do not attempt to test the vehicle on a
dynamometer (such as the dynamom-
eters used by some states for emissions
testing) , or similar equipment. Doing so
may cause damage to the drivetrain or
the high voltage battery. Make sure you
inform test facility personnel that your
vehicle is a hybrid. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.
● Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) , D (Drive) or B
(Brake) . Always depress the brake
pedal until shifting is completed. Fail-
ure to do so could cause you to lose
control and have an accident.
● Never shift to P (Park) or R (Reverse)
while the vehicle is moving. This could
cause an accident.
CAUTION
When stopping the vehicle on an uphill
grade, do not hold the vehicle by depress-
ing the accelerator pedal. The foot brake
should be used for this purpose.
The eCVT in your vehicle is electronically con-
trolled to produce maximum power and smooth
operation.
The recommended operating procedures for this
transmission are shown on the following pages.
Follow these procedures for maximum vehicle
performance and driving enjoyment.
Starting the vehicle
1. After starting the Hybrid System, fully de- press the foot brake pedal before moving the
shift selector out of the P (Park) position.
2. Keep the foot brake pedal depressed and move the shift selector into a driving gear.
3. Release the foot brake, then gradually start the vehicle in motion.
4. Stop the vehicle completely before shifting the selector to the P (Park) position.
The eCVT is designed so the foot brake
pedal MUST be depressed before shifting
from P (Park) to any drive position while
the ignition switch is in the ON position.
DRIVING THE VEHICLE
Starting and driving5-11

R (Reverse):
CAUTION
To prevent transmission damage, use the
P (Park) or R (Reverse) position only when
the vehicle is completely stopped.
Use the R (Reverse) position to back up. Make
sure the vehicle is completely stopped before
selecting the R (Reverse) position. The brake
pedal must be depressed to move the shift
selector from P (Park) , N (Neutral) or any
drive position to R (Reverse) .
N (Neutral):
Neither forward nor reverse gear is engaged. Do
not leave the shift selector in the N (Neutral)
position for a long period of time. In the N (Neu-
tral) position, the gasoline engine operates but
electricity cannot be generated. The high voltage
battery will be discharged requiring unnecessary
engine power to recharge.
Depending on the status of the engine before
shifting into the N (Neutral) position, the engine
may not operate. D (Drive):
Use this position for all normal forward driving.
B (Brake) low gear:
Downshift into the B position with your foot off
the accelerator pedal to use engine braking while
driving.
You may feel that engine braking is less effective
than a conventional vehicle when driving at higher
speeds.
Driving with the transmission in the B position for
long periods of time may cause a decrease in fuel
economy.
Shift lock release
If the battery charge is low or discharged, the
shift selector may not be moved from the P (Park)
position even with the brake pedal depressed
and the shift selector button pushed.
It will be necessary to jump start or have your
battery charged, see “Jump starting” in the “In
case of emergency” section. Contact your
NISSAN dealer or a professional towing service.

3. For cap removal it must be used or if it is available a plastic trim tool can be used
4. Using a protective cloth on the tip ofa3mm screwdriver, remove the shift lock release
cover.
● If available, a plastic trim tool can also be
used.
5. Insert the small screwdriver in the shift lock release slot and push down.
6. Move the shift selector to the N (Neutral) position while holding down the shift lock
release.
7. Push the ignition switch to the ON position to unlock the steering wheel. Now the ve-
hicle may be moved to the desired location.
If the shift selector cannot be moved out of P
(Park) , have a NISSAN dealer check the trans-
mission as soon as possible.WARNING
If the shift selector cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
WARNING
● Be sure the parking brake is fully re-
leased before driving. Failure to do so
can cause brake failure and lead to an
accident.
● Do not release the parking brake from
outside the vehicle.
● Do not use the shift selector in place of
the parking brake. When parking, be
sure the parking brake is fully engaged.
● Do not leave children unattended in a
vehicle. They could release the parking
brake and cause an accident.

5-14Starting and driving

CAUTION
During the first 1,200 miles (2,000 km) ,
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy of
your new vehicle. Failure to follow these
recommendations may result in short-
ened engine life and reduced engine
performance.● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 miles
(800 km) . Your engine, axle or other parts
could be damaged. ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
● Avoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
● Air conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.
● When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag. ●
Use the recommended viscosity engine oil.
See “Engine oil and oil filter recommenda-
tions” in “Technical and consumer informa-
tion” later in this manual.
BREAK-IN SCHEDULE INCREASING FUEL ECONOMY
Starting and driving5-17

Hydraulic system
The brake system has separate hydraulic circuits.
If one circuit malfunctions, you will still have brak-
ing at other wheels.
However, the brake pedal will have to be de-
pressed harder and your stopping distance will
increase. The brake system warning light will also
come on.
Brake actuator
The brake actuator uses a pump to provide
power assisted braking.
The brake warning light comes on if the actuator
is not functioning properly. The brake pedal will
be hard to depress and stopping distance will
increase. Depress the brake pedal firmly to stop
the vehicle in a safe place and contact a NISSAN
dealer.
If the brake pedal is depressed repeatedly, the
brake warning light may turn on. However this is
normal if the light turns off after a few seconds.
Noise may be heard in the engine room under the
following conditions. This is a normal operating
characteristic and does not indicate a malfunc-
tion.● When you open a door.
● When the brake pedal is depressed firmly. ●
When the brake pedal is depressed repeat-
edly.
● When the Hybrid System is in the READY
mode.
● When the Hybrid System is turned off.
It may be hard to depress the brake pedal or the
pedal stroke may be short with the Hybrid System
OFF. This is not a malfunction.
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.
Parking brake break-in
Break-in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drum/rotors are replaced, in order to assure the
best brake performance.
This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
