check the sensor’s functionality, within
certain limitations. The system may not
detect some forms of obstruction of the
sensor area such as ice, snow, stickers,
etc. In these cases, the system may not
be able to warn the driver properly. Be
sure that you check, clean and clear the
sensor area regularly.
● Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.

When driving on roads with limited road struc-
tures or buildings (for example, long bridges,
deserts, snow fields, driving next to long walls) ,
the system may illuminate the system warning
light (orange) and display the “Unavailable: Front
Radar Obstruction” message.
Action to take
If the warning light (orange) comes on, stop the
vehicle in a safe place, place the shift lever in the
P (Park) position and turn the engine off. Clean
the radar cover on the lower grille with a soft
cloth, and restart the engine. If the warning light
continues to illuminate, have the PFCW system
checked. It is recommended that you visit a
NISSAN dealer for this service.
NOTE:
If the FEB system stops working, the PFCW
system (if so equipped) will also stop work-
ing.
SYSTEM MALFUNCTION
If the PFCW system malfunctions, it will be
turned off automatically, a chime will sound, the
FEB system warning light (orange) will illuminate
and the warning message [Malfunction] will ap-
pear in the vehicle information display.Action to take
If the warning light (orange) comes on, stop the
vehicle in a safe location, turn the engine off and
restart the engine. If the warning light continues
to illuminate, have the PFCW system checked. It
is recommended that you visit a NISSAN dealer
for this service.
SYSTEM MAINTENANCE
The sensorAis located behind the lower grille
of the front bumper.
To keep the system operating properly, be sure to
observe the following:
● Always keep the sensor area of the front
bumper clean.
● Do not strike or damage the areas around
the sensor.
● Do not cover or attach stickers or similar
objects on the front bumper near the sensor
area. This could cause failure or malfunction.

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked. It is recommended that you visit a
NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above3-6mph(5
- 10 km/h). The speed varies according to road
conditions.When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly ap-
plies and releases hydraulic pressure. This action
is similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional brake booster even with light pedal force.
WARNING
The brake assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the driv-
er’s responsibility to stay alert, drive
safely and be in control of the vehicle at all
times.
The VDC system uses various sensors to monitor
driver inputs and vehicle motion. Under certain
driving conditions, the VDC system helps to per-
form the following functions:
● Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
● Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
● Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss of
vehicle control in all driving situations.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It monitors
tire pressure of all tires except the spare. When
the low tire pressure warning light is lit, and the
“Tire Pressure Low - Add Air” warning appears in
the vehicle information display, one or more of
your tires is significantly under-inflated. If
equipped, the system also displays pressure of
all tires (except the spare tire) on the display
screen by sending a signal from a sensor that is
installed in each wheel. 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 additional information, refer to
“Warning lights, indicator lights and audible re-
minders” in the “Instruments and controls” sec-
tion and “Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” section of
this manual.
WARNING
●Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use.
● If the low tire pressure warning light
illuminates while driving, avoid sudden
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 pressure
shown on the Tire and Loading Informa-
tion 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. It is recommended that you
visit a NISSAN dealer for this service. ●
Since the spare tire is not equipped with
the TPMS, 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 warn-
ing light will flash for approximately
one minute. The light will remain on
after one minute. Have your tires re-
placed and/or TPMS system reset as
soon as possible. It is recommended
that you visit a NISSAN dealer for these
services.
● 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.
● If the light still comes on while driving
after adjusting the tire pressure, a tire
may be flat or the TPMS may be mal-
functioning. If you have a flat tire, re-
place it with a spare tire as soon as
possible. If no tire is flat and all tires are
properly inflated, it is recommended
that you visit a NISSAN dealer.
FLAT TIRE
In case of emergency6-3

Occasionally remove loose dust from the interior
trim, plastic parts and seats using a vacuum
cleaner or soft bristled brush. Wipe the vinyl and
leather (if so equipped) surfaces with a clean,
soft cloth dampened in mild soap solution, then
wipe clean with a dry, soft cloth.
Regular care and cleaning is required in order to
maintain the appearance of the leather (if so
equipped) .
Before using any fabric protector, read the manu-
facturer’s recommendations. Some fabric pro-
tectors contain chemicals that may stain or
bleach the seat material.
Use a cloth dampened only with water to clean
the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can dam-
age the seat or occupant classification
sensor. This can also affect the operation
of the air bag system and result in serious
personal injury.
CAUTION
●Never use benzine, thinner or any simi-
lar material.
● Small dirt particles can be abrasive and
damaging to leather surfaces and
should be removed promptly. Do not
use saddle soap, car waxes, polishes,
oils, cleaning fluids, solvents, deter-
gents or ammonia-based cleaners as
they may damage the leather’s natural
finish.
● Never use fabric protectors unless rec-
ommended by the manufacturer.
● Do not use glass or plastic cleaner on
meter or gauge lens covers. It may dam-
age the lens cover.
AIR FRESHENERS
Most air fresheners use a solvent that could affect
the vehicle interior. If you use an air freshener,
take the following precautions:
● Hanging-type air fresheners can cause per-
manent discoloration when they contact ve-
hicle interior surfaces. Place the air fresh-
ener in a location that allows it to hang free
and not contact an interior surface. ●
Liquid-type air fresheners typically clip on
the vents. These products can cause imme-
diate damage and discoloration when
spilled on interior surfaces.
Carefully read and follow the manufacturer’s in-
structions before using the air fresheners.

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should con-
tact the electric medical equipment
manufacturer for the possible influ-
ences before use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS) . It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the Tire Pressure
Low - Add Air warning appears in the
vehicle information display, one or more of
your tires is significantly under-inflated. If
equipped, the system also displays pres-
sure of all tires (except the spare tire) on
the display screen by sending a signal
from a sensor that is installed in each
wheel. The TPMS will activate only when the
vehicle is driven at speeds above 16 mph
(25 km/h). Also, this system may not de-
tect a sudden drop in tire pressure (for
example a flat tire while driving) .
For additional information, refer to “Low
tire pressure warning light” in the “Instru-
ments and controls” section, “Tire Pres-
sure Monitoring System (TPMS)” in the
“Starting and driving” section and “Flat
tire” in the “In case of emergency” section
of this manual.
Tire inflation pressure
Check the tire pressures (including the spare)
often and always prior to long distance trips. The
recommended tire pressure specifications are
shown on the F.M.V.S.S./C.M.V.S.S. certification
label or the Tire and Loading Information label
under the “Cold Tire Pressure” heading. The Tire
and Loading Information label is affixed to the
driver side center pillar. Tire pressures should be
checked regularly because:
● Most tires naturally lose air over time.
● Tires can lose air suddenly when driven over
potholes or other objects or if the vehicle
strikes a curb while parking. The tire pressures should be checked when the
tires are cold. The tires are considered COLD
after the vehicle has been parked for 3 or more
hours, or driven less than 1 mile (1.6 km) at
moderate speeds.
The TPMS with Easy-Fill Tire Alert (if so
equipped) provides visual and audible signals
outside the vehicle for inflating tires to the recom-
mended COLD tire pressure. For additional infor-
mation, refer to “TPMS with Easy-Fill Tire Alert” in
the “Starting and driving” section of this manual.
Incorrect tire pressure, including under in-
flation, may adversely affect tire life and
vehicle handling.WARNING
●
Improperly inflated tires can fail sud-
denly and cause an accident.
WHEELS AND TIRES
Do-it-yourself8-27

●The TPMS sensor may be damaged if it
is not handled correctly. Be careful
when handling the TPMS sensor.
● When replacing the TPMS sensor, the
ID registration may be required. It is
recommended that you visit a NISSAN
dealer for ID registration.
● Do not use a valve stem cap that is not
specified by NISSAN. The valve stem
cap may become stuck.
● Be sure that the valve stem caps are
correctly fitted. Otherwise the valve may
be clogged up with dirt and cause a
malfunction or loss of pressure.
● Do not install a damaged or deformed
wheel or tire even if it has been re-
paired. Such wheels or tires could have
structural damage and could fail with-
out warning.
● The use of retread tires is not
recommended.
● For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.Wheel balance
Unbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can get
out of balance. Therefore, they should be bal-
anced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
● For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
Care of wheels
● Wash the wheels when washing the vehicle
to maintain their appearance.
● Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
● Do not use abrasive cleaners when washing
the wheels.
● Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead. ●
NISSAN recommends waxing the road
wheels to protect against road salt in areas
where it is used during winter.
Spare tire (TEMPORARY USE ONLY
spare tire)
Since the spare tire is not equipped with the
TPMS, when a spare tire is mounted (TEMPO-
RARY USE ONLY or conventional) , the TPMS
will not function.
Observe the following precautions if the TEM-
PORARY USE ONLY spare tire must be used.
Otherwise, your vehicle could be damaged or
involved in an accident:
WARNING
● The spare tire should be used for emer-
gency use only. It should be replaced
with the standard tire at the first oppor-
tunity to avoid possible tire or differen-
tial damage.
● Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
