Autolight system
The autolight system allows the headlights
to turn on and off automatically. The auto-
light system can:
• Turn on the headlights, front parking, tail,license plate and instrument panel lights
automatically when it is dark.
• Turn off all the lights when it is light.
• Keep all the lights on for a period of time af ter you place the ignition switch in the
OFF position and all doors are closed.
NOTE:
Autolight activation sensitivity and
the time delay for autolight shutoff
can be adjusted. For additional infor-
mation, refer to “Vehicle information
display ” in this section.
To turn on the autolight system:
1. Turn the headlight switch to the AUTO position
O1.
2. Turn the ignition switch to ON.
3. The autolight system automatically turns the headlights on and off.
Initially, if the ignition switch is placed in the
OFF position and a door is opened and lef t
open, the headlights remain on for a period
of time. If another door is opened while the
headlights are on, then the timer is reset.
To turn the autolight system off, turn the
switch to the OFF,
,orposition. Be sure you do not put anything on top
of the autolight sensor located in the top
side
O1of the instrument panel. The au-
tolight sensor controls the autolight; if it
is covered, the autolight sensor reacts as
if it is dark out and the headlights will
illuminate. If this occurs while parked
with the engine off and the ignition
switch placed in the ON position, your
vehicle's battery could become dis-
charged.

•If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light off. If you have
a flat tire, replace it with a spare tire
as soon as possible. (For additional
information on changing a flat tire,
refer to “Flat tire” in the “In case of
emergency ” section of this manual.) •
When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is
replaced, the TPMS will not function
and the low tire pressure warning
light will flash for approximately 1
minute. The light will remain on af ter
1 minute. Have your tires replaced
and/or TPMS reset as soon as pos-
sible. It is recommended that you
visit a NISSAN dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect 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 pres-
sure sensors.
CAUTION
Do not place metalized film or any
metal parts (antenna, etc.) on the win-
dows. This may cause poor reception of
the signals from the tire pressure sen-
sors, and the TPMS will not function
properly. Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate.
Some examples are:
• Facilities or electric devices using similar
radio frequencies are near the vehicle.
• If a transmitter set to similar frequencies is being used in or near the vehicle.
• If a computer (or similar equipment) or a DC/AC converter is being used in or near
the vehicle.
The low tire pressure warning light may
illuminate in the following cases:
• If the vehicle is equipped with a wheel and tire without TPMS.
• If the TPMS has been replaced and the ID has not been registered.
• If the wheel is not originally specified by NISSAN.

TPMS with Easy-Fill Tire Alert
When adding air to an under-inflated tire,
the TPMS with Easy-Fill Tire Alert provides
visual and audible signals outside the ve-
hicle to help you inflate the tires to the rec-
ommended COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level place.2. Apply the parking brake and place the
shif t lever in the P (Park) position (if so
equipped).
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation:
1. Add air to the tire.
2. Af ter a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more thanapproximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the
tire briefly to release pressure. When
the pressure reaches the designated
pressure, the horn beeps once.
• If the hazard indicator does not flash within approximately 15 seconds af ter
starting to inflate the tire, it indicates
that the Easy-Fill Tire Alert is not oper-
ating. • The TPMS will not activate the Easy-Fill
Tire Alert under the following condi-
tions:
– If there is interference from an ex- ternal device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the
tire.
– There is a malfunction in the TPMS system.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire’s pressure sensor is not registered to
the system.
– The battery of the tire pressure sensor is low.
• If the Easy-Fill Tire Alert does not oper- ate due to TPMS interference, move
the vehicle about 3 f t (1 m) backward
or forward and try again.
If the Easy-Fill Tire Alert is not working, use a
tire pressure gauge.
5-8Starting and driving

The BSW system uses radar sensorsO1
installed near the rear bumper to detect
other vehicles in an adjacent lane.The radar sensors can detect vehicles on
either side of your vehicle within the detec-
tion zone shown as illustrated. This detec-
tion zone starts from the outside mirror of
your vehicle and extends approximately 10
f t (3.0 m) behind the rear bumper, and ap-
proximately 10 f t (3.0 m) sideways.

Detection zone

1. Side BSW/RCTA Indicator Light
2. BSW/RCTA Indicator
BSW SYSTEM OPERATION
The BSW system operates above approxi-
mately 20 mph (32 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side BSW/RCTA indica-
tor light (1) illuminates. If the turn signal is
then activated, the system chimes (twice)
and the side BSW/RCTA indicator light
flashes. The BSW indicator light continues
to flash until the detected vehicles leaves
the detection zone.
The side BSW/RCTA indicator light illumi-
nates for a few seconds when the ignition
switch is placed in the ON position.
The brightness of the side BSW/RCTA indi-
cator light is adjusted automatically de-
pending on the brightness of the ambient
light.
If a vehicle comes into the detection zone
af ter the driver activates the turn signal,
then only the side BSW/RCTA indicator light
flashes and no chime sounds. For addi-
tional information, refer to “BSW driving
situations” in this section.
