Cruise set switch indicatorlight
The light comes on while the vehicle speed is
controlled by the cruise control system. If the light
blinks while the engine is running, it may indicate
the cruise control system is not functioning prop-
erly. Have the system checked by a NISSAN
dealer.

Engine start operation indicator (CVT
models)
This indicator illuminates when the ignition switch
is placed in the LOCK, OFF, ACC or ON position
with the shift selector in the P (Park) position.
This indicator means that the engine will start by
pushing the push-button ignition switch with the
brake pedal depressed.
Engine start operation indicator (M/T
models)
This indicator illuminates when the ignition switch
is placed in the LOCK, OFF, ACC or ON position
with the shift selector in neutral and the parking
brake on.
This indicator means that the engine will start by
pushing the ignition switch with the clutch and
the brake pedal depressed.
NISSAN Intelligent Key™ insertion indica-
tor
This indicator illuminates when the Intelligent Key
needs to be inserted into the Intelligent Key port.
(For example, the Intelligent Key battery is dis-
charged.)
If this indicator illuminates, insert the Intelligent
Key into the Intelligent Key port in the correct
direction. See “Push-button ignition switch” in
the “Starting and driving” section.NISSAN Intelligent Key™ removal indica-
tor
This indicator illuminates when the driver’s door
is opened with the ignition switch placed in the
OFF position and the Intelligent Key placed in the
Intelligent Key port. A key reminder chime also
sounds.
If this indicator illuminates, remove the Intelligent
Key from the Intelligent Key port and take it with
you when leaving the vehicle.
NISSAN Intelligent Key™ battery dis-
charge indicator
This indicator illuminates when the Intelligent Key
battery is running out of power.
If this indicator illuminates, replace the battery
with a new one. See “NISSAN Intelligent Key™” in
the “Maintenance and do-it-yourself” section.
Loose fuel cap warning
This warning appears when the fuel-filler cap is
not tightened correctly after the vehicle has been
refueled. See “Fuel-filler cap” in the “Pre-driving
checks and adjustments” section.
Check tire pressure warning
This warning appears when the low tire pressure
warning light in the meter illuminates and low tire
pressure is detected. If this warning appears,
stop the vehicle and adjust the tire pressure to
the recommended COLD tire pressure shown on
the Tire and Loading Information label. See “Low
tire pressure warning light” earlier in this section
and “Tire Pressure Monitoring System (TPMS)”
in the “Starting and driving” section.

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.
Continuously Variable Transmission
(CVT) model:

BEFORE STARTING THE ENGINE STARTING THE ENGINE
5-10Starting and driving

Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid temperature
protection mode. If the fluid temperature be-
comes too high (for example, when climbing
steep grades in high temperature with heavy
loads, such as when towing a trailer) , engine
power and, under some conditions, vehicle
speed will be decreased automatically to reduce
the chance of transmission damage. Vehicle
speed can be controlled with the accelerator
pedal, but the engine and vehicle speed may be
limited.
Fail-safe
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. The MIL may
come on to indicate the fail-safe mode is
activated, see “Malfunction Indicator Light
(MIL)” in the “Instrument and controls” sec-tion. This will occur even if all electrical
circuits are functioning properly. In this
case, place the ignition switch in the OFF
position and wait for 10 seconds. Then
push the switch back to the ON position.
The vehicle should return to its normal op-
erating condition. If it does not return to its
normal operating condition, have a
NISSAN dealer check the transmission and
repair if necessary.

To shut off the engine in an emergency situation
while driving perform the following procedure:
– Rapidly push the push-button ignition switch 3consecutive times, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire pres-
sure of all tires except the spare. When the low
tire pressure warning light is lit, and the CHECK
TIRE PRESSURE warning appears in the vehicle
information display, one or more of your tires is
significantly under-inflated. If the vehicle is being
driven with low tire pressure, the TPMS will acti-
vate and warn you of it by the low tire pressure
warning light. This system will activate only when
the vehicle is driven at speeds above 16 MPH
(25 km/h) . For more details, refer to
“Warning/indicator lights and audible reminders”
in the “Instruments and controls” section, and
“Tire Pressure Monitoring System (TPMS)” in the
“Starting and driving” section.

Seat beltsCheck that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Steering wheel Check for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimes Make sure all
warning lights and chimes are operating properly.
Windshield wiper and washer* Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defroster Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery* Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level. Brake and clutch fluid levels*
Make sure that
the brake and clutch fluid level is between the
MIN and MAX lines on the reservoir.
Engine coolant level* Check the coolant level
when the engine is cold.
Engine drive belts* Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level* Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust system Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by a NISSAN dealer. See “Ex-
haust gas (carbon monoxide)” in the “Starting
and driving” section of this manual.
Fluid leaks Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately. Power steering fluid level* and lines
Check
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
Underbody The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield–washer fluid* Check that there is
adequate fluid in the reservoir.
