5. To stop the engine, move the shif t leverto the P (Park) position and push the
ignition switch to the OFF position.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as: 1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not
running (phone chargers, GPS, DVD
players, etc.).
2. The vehicle is not driven regularly
and/or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
REMOTE ENGINE START
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t
lever can be moved from the P (Park) posi-
tion. To place the ignition switch in the ON
position, follow these steps: 1. Make sure that the Intelligent Key is on you. 2. Apply the brake.
3. Push the ignition switch once to the ON
position.
For additional information, refer to “NISSAN
Intelligent Key®” in the “Pre-driving checks
and adjustments” section of this manual.
CONTINUOUSLY VARIABLE
TRANSMISSION (CVT)
WARNING
∙ Do not depress the accelerator pedal while shif ting from P (Park) or N (Neu-
tral) to R (Reverse), D (Drive), L (Low) or
manual shif t mode (if so equipped).
Always depress the brake pedal until
shif ting is completed. Failure to do so
could cause you to lose control and
have an accident.
∙ Cold engine idle speed is high, so use caution when shif ting into a forward
or reverse gear before the engine has
warmed up.
∙ Do not downshif t abruptly on slippery roads. This may cause a loss of
control.
∙ Never shif t to either the P (Park) or R (Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is re-
versing. This could cause an accident
or damage the transmission.
DRIVING THE VEHICLE
5-18Starting and driving

When the vehicle is stopped on a hill, the hill
start assist system automatically keeps
the brakes applied to help prevent the ve-
hicle from rolling backward in the time it
takes the driver to release the brake pedal
and apply the accelerator.
The hill start assist system will operate au-
tomatically under the following conditions:∙ The transmission is shif ted to a forward or reverse gear.
∙ The vehicle is stopped completely on a hill by applying the brake. The maxi-
mum holding time is 2 seconds. Af ter
2 seconds the vehicle will begin to roll
back and the hill start assist system will
stop operating completely.
The hill start assist system will not operate
when the shif t lever is placed in the N (Neu-
tral) or P (Park) position or on a flat and level
road. The RSS sounds a tone to inform the driver
of obstacles near the bumper.
When the “DISPLAY” key is on, the sonar
view will automatically appear in the
touch-screen display. An additional view of
the sonar status will appear in the vehicle
information display for reference.WARNING
∙ The RSS is a convenience but it is not a
substitute for proper parking.
∙ The driver is always responsible for safety during parking and other ma-
neuvers. Always look around and
check that it is safe to do so before
parking.
∙ Read and understand the limitations of the RSS as contained in this section.
The colors of the corner sonar indica-
tor and the distance guide lines in the
rear view indicate different distances
to the object.
∙ Inclement weather or ultrasonic sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may affect
the function of the system; this may
include reduced performance or a
false activation.
∙ This function is designed as an aid to the driver in detecting large station-
ary objects to help avoid damaging
the vehicle.

equipped)
Starting and driving5-175

SYSTEM MAINTENANCE
The sonar sensors1are located on the
rear bumper. Always keep the area near
the sonar sensors clean.
The sonar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the sonar sensors.
Check for and remove objects obstructing
the area around the sonar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the sonar sensors is damaged due to a
collision.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry function on the Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
refer to “Engine cooling system” in the “Do-
it-yourself ” section of this manual.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, refer to “Battery”
in the “Do-it-yourself ” section of this
manual.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
∙ Park the vehicle on a level surface, ap-ply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park).
∙ Be sure the ignition key is in the OFF or LOCK position when performing any
parts replacement or repairs.
∙ If you must work with the engine run- ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
∙ It is advisable to secure or remove any loose clothing and remove any jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position and the
engine is not running. To avoid injury, al-
ways disconnect the negative battery
cable before working near the fan.
∙ If you must run the engine in an en- closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
∙ Never get under the vehicle while it is supported only by a jack. If it is neces-
sary to work under the vehicle, sup-
port it with safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ On gasoline engine models, the fuel filter or fuel lines should be serviced. It
is recommended that you visit a
NISSAN dealer for this service because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
∙ Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down. ∙
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
∙ Never leave the engine or the trans- mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.
