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.

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

∙In the manual shif t mode, the trans-
mission may not shif t to the selected
gear. This helps maintain driving per-
formance and reduces the chance of
vehicle damage or loss of control.
∙ In the manual shif t mode, the trans-
mission may shif t up automatically to
a higher range than selected if the
engine speed is too high. When the
vehicle speed decreases, the trans-
mission automatically shif ts down
and shif ts to 1st gear before the ve-
hicle comes to a stop.
∙ Continuously Variable Transmission (CVT) operation is limited to automatic
drive mode when CVT fluid tempera-
ture is extremely low even if manual
shif t mode is selected. This is not a mal-
function. When CVT fluid warms up,
manual mode can be selected.
∙ When the CVT fluid temperature is high, the shif t range may upshif t in lower
rpm than usual. This is not a malfunc-
tion.
Shif t lock release
If the battery charge is low or discharged,
the shif t lever may not be moved from the
P (Park) position even with the brake pedal
depressed and the shif t lever button
pressed.
It will be necessary to jump start or have
your battery charged. For additional infor-
mation, refer to “Jump starting” in the “In
case of emergency” section of this manual.
Contact a NISSAN dealer or a professional
towing service. To move the shif t lever, complete the fol-
lowing procedure:
1. Push the ignition switch to the LOCK position.
2. Apply the parking brake.
3. Using a protective cloth on the tip of a 3 mm screwdriver, remove the shif t
lock release cover.

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.
