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.

Locking doors
1. Move the shift selector to the P (Park) posi-tion, place the ignition switch in the LOCK
position and make sure you carry the Intelli-
gent Key with you.
2. Close all doors.
3. Push any door handle request switch
1
while carrying the Intelligent Key with you.
4. All doors and the trunk will lock.
5. The hazard warning lights flash twice and the outside buzzer sounds twice. NOTE:
● Doors lock with the door handle request
switch while the ignition switch is not in the
LOCK position.
● Doors do not lock by pushing the door
handle request switch while any door is
open. However, doors lock with the me-
chanical key even if any door is open.
● Doors do not lock with the door handle
request switch with the Intelligent Key inside
the vehicle and a beep sounds to warn you.
However, when an Intelligent Key is inside
the vehicle, doors can be locked with an-
other Intelligent Key.

WARNING
●Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
●The Intelligent Key transmits radio waves
when the buttons are pressed. The FAA
advises the radio waves may affect air-
craft navigation and communication sys-
tems. Do not operate the Intelligent Key
while on an airplane. Make sure the but-
tons are not operated unintentionally
when the unit is stored for a flight.
The Intelligent Key can operate all the door locks
using the remote controller function. The operat-
ing environment and/or conditions may affect the
Intelligent Key operation.
Be sure to read the following before using the
Intelligent Key.

●The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH (25
km/h) . Also, this system may not detect a
sudden drop in tire pressure (for example a
flat tire while driving) .
● The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After all 4 tires are inflated to the
recommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h)
to activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.
● The CHECK TIRE PRESSURE warning ap-
pears in the vehicle information display when
the low tire pressure warning light is illumi-
nated and low tire pressure is detected. The
CHECK TIRE PRESSURE warning turns off
when the low tire pressure warning light
turns off.
● The CHECK TIRE PRESSURE warning
does not appear if the low tire pressure
warning light illuminates to indicate a TPMS
malfunction. ●
Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. This may cause
the low tire pressure warning light to illumi-
nate. If the warning light illuminates in low
ambient temperature, check the tire pres-
sure for all four tires.
● The Tire and Loading Information label (also
referred to as the vehicle placard or tire
inflation pressure label) is located in the
driver’s door opening.
For additional information, see “Low tire pressure
warning light” in the “Instruments and controls”
section and “Tire Pressure Monitoring System
(TPMS)” in the “In case of emergency” section.

●When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.

3. When appropriate, slowly release the accel-erator pedal to gradually slow the vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from traffic if possible.
5. Lightly apply the brake pedal to gradually stop the vehicle.
6. Turn on the hazard warning flashers and either contact a roadside emergency service
to change the tire or see “Changing a flat
tire” in the “In case of emergency” section of
this manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING

When the ignition switch is pushed without de-
pressing the brake pedal (CVT) or the clutch
pedal (M/T) , the ignition switch position will illu-
minate as follows:
Push center● once to change to ACC.
● two times to change to ON.
● three times to return to OFF.
The ignition switch will automatically return to the
LOCK position when any door is either opened or
closed with the switch in the OFF position. The ignition lock is designed so that the ignition
switch position cannot be switched to OFF until
the shift selector is moved to the P (Park) position
(CVT) or N (Neutral) position (M/T) .
When the ignition switch cannot be pushed to-
ward the OFF position, proceed as follows:
1. Move the shift selector into the P (Park) position (CVT) or N (Neutral) position (M/T) .
2. Push the ignition switch. The ignition switch position will change to the ON position.
3. Push the ignition switch again to the OFF position.
The shift selector can be moved from the P
(Park) position if the ignition switch is in
the ON position and the brake pedal is
depressed.
If the battery of the vehicle is discharged,
the push-button ignition switch cannot be
moved from the LOCK position.
Some indicators and warnings for operation are
displayed on the vehicle information display. See
“Vehicle information display” in the “Instruments
and controls” section.
