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.
LCE2131
FIRST AID KIT (if so equipped) FLAT TIRE
In case of emergency6-3

●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. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended 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.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to P (Park) . 4. Turn off the engine.
5. Raise the hood to warn other traffic and to
signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from traffic
and clear of the vehicle.
WARNING
●Make sure the parking brake is securely
applied and the CVT is shifted into P
(Park) .
● Never change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for profes-
sional road assistance.
A. Blocks
B. Flat tire
Blocking wheels
Place suitable blocks at both the front and back
of the wheel diagonally opposite the flat tire to
prevent the vehicle from moving when it is jacked
up.
WARNING
Be sure to block the wheel as the vehicle
may move and result in personal injury.
LCE2142
6-4In case of emergency

CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
●Do not use a cleaner that uses strong
acid or alkali contents to clean the
wheels.
● Do not apply wheel cleaners to the
wheels when they are hot. The wheel
temperature should be the same as am-
bient temperature.
● Rinse the wheel to completely remove
the cleaner within 15 minutes after the
cleaner is applied.
CHROME PARTS
Clean all chrome parts regularly with a non-
abrasive chrome polish to maintain the finish.
TIRE DRESSINGS
NISSAN does not recommend the use of tire
dressings. Tire manufacturers apply a coating to
the tires to help reduce discoloration of the rub-
ber. If a tire dressing is applied to the tires, it may
react with the coating and form a compound. This
compound may come off the tire while driving and
stain the vehicle paint. If you choose to use a tire dressing, take the
following precautions:
● Use a water-based tire dressing. The coat-
ing on the tire dissolves more easily than
with an oil-based tire dressing.
● Apply a light coat of tire dressing to help
prevent it from entering the tire
tread/grooves (where it would be difficult to
remove) .
● Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is com-
pletely removed from the tire tread/grooves.
● Allow the tire dressing to dry as recom-
mended by the tire dressing manufacturer. 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 surfaces with a clean, soft cloth damp-
ened 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.
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.

●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. Contact
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.
Maintenance and do-it-yourself8-45

WARNING
●The front air bags ordinarily will not
inflate in the event of a side impact, rear
impact, rollover, or lower severity fron-
tal collision. Always wear your seat
belts to help reduce the risk or severity
of injury in various kinds of accidents.
●The front passenger air bag will not
inflate if the passenger air bag status
light is lit. For additional information,
refer to “Front passenger air bag and
status light” in this section.●The seat belts and the front air bags are
most effective when you are sitting well
back and upright in the seat. The front
air bags inflate with great force. Even
with the NISSAN Advanced Air Bag Sys-
tem, if you are unrestrained, leaning
forward, sitting sideways or out of posi-
tion in any way, you are at greater risk of
injury or death in a crash. You may also
receive serious or fatal injuries from the
front air bag if you are up against it
when it inflates. Always sit back againstthe seatback and as far away as practi-
cal from the steering wheel or instru-
ment panel. Always properly use the
seat belts.
●The driver and front passenger seat belt
buckles are equipped with sensors that
detect if the seat belts are fastened. The
NISSAN Advanced Air Bag System
monitors the severity of a collision and
seat belt usage, then inflates the air
bags as needed. Failure to properly
wear seat belts can increase the risk or
severity of injury in an accident.
●The front passenger seat is equipped
with an occupant classification sensor
(weight sensor) that turns the front pas-
senger air bag OFF under some condi-
tions. This sensor is only used in this
seat. Failure to be properly seated and
wearing the seat belt can increase the
risk or severity of injury in an accident.
For additional information, refer to
“Front passenger air bag and status
light” in this section.
●Keep hands on the outside of the steer-
ing wheel. Placing them inside the
steering wheel rim could increase the
risk that they are injured when the front
air bag inflates.

NISSAN Advanced Air Bag System
(front seats)
WARNING
To ensure proper operation of the passen-
ger’s NISSAN Advanced Air Bag System,
please observe the following items.
●Do not allow a passenger in the rear
bench seats to push or pull on the seat-
back pocket.●Do not place heavy loads heavier than
2.2 lb (1 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
●Make sure that there is nothing press-
ing against the rear of the seatback,
such as a child restraint installed in the
rear seat or an object stored on the
floor.
●Make sure that there is no object placed
under the front passenger seat.
●Make sure that there is no object placed
between the seat cushion and center
console or between the seat cushion
and the door.
●If a forward-facing child restraint is in-
stalled in the front passenger seat, do
not position the front passenger seat so
the child restraint contacts the instru-
ment panel. If the child restraint does
contact the instrument panel, the sys-
tem may determine the seat is occupied
and the passenger air bag may deploy
in a collision. Also the front passenger
air bag status light may not illuminate.
For additional information about in-
stalling and using child restraints, refer
to “Child restraints” in this section.●Confirm the operating condition with
the front passenger air bag status light.
●If you notice that the front passenger air
bag status light is not operating as de-
scribed in this section, it is recom-
mended that you visit a NISSAN dealer
for this service.
●Until you have confirmed with a dealer
that your passenger seat occupant clas-
sification system is working properly,
position the occupants in the rear seat-
ing positions.
●Do not position the front passenger
seat so it contacts the rear seat. If the
front seat does contact the rear seat,
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status light
may illuminate and the supplemental
air bag warning light may flash.
This vehicle is equipped with the NISSAN Ad-
vanced Air Bag System for the driver and front
passenger seats. This system is designed to
meet certification requirements under U.S. regu-
lations. It is also permitted in Canada.However,
all of the information, cautions and warn-
ings in this manual still apply and must be
followed.
SSS0159

The driver supplemental front-impact air bag is
located in the center of the steering wheel. The
front passenger supplemental front-impact air
bag is mounted in the dashboard above the glove
box. The front air bags are designed to inflate in
higher severity frontal collisions, although they
may inflate if the forces in another type of collision
are similar to those of a higher severity frontal
impact. They may not inflate in certain frontal
collisions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag sys-
tem operation.
The NISSAN Advanced Air Bag System monitors
information from the crash zone sensor, the Air
bag Control Unit (ACU) , seat belt buckle sensors
and occupation classification sensor (weight
sensor) . Inflator operation is based on the sever-
ity of a collision and seat belt usage for the driver.
For the front passenger, the occupant classifica-
tion sensor is also monitored. Based on informa-
tion from the sensor, only one front air bag may
inflate in a crash, depending on the crash severity
and whether the front occupants are belted or
unbelted. Additionally, the front passenger air
bag may be automatically turned off under some
conditions, depending on the weight detected on
the front passenger seat and how the seat belt is
used. If the front passenger air bag is OFF, the
front passenger air bag status light will be illumi-
nated. For additional information, refer to “Frontpassenger air bag and status light” in this section.
One front air bag inflating does not indicate im-
proper performance of the system.
If you have any questions about your air bag
system, it is recommended that you visit a
NISSAN dealer to obtain information about the
system. If you are considering modification of
your vehicle due to a disability, you may also
contact NISSAN. Contact information is con-
tained in the front of this Owner’s Manual.
When a front air bag inflates, a fairly loud noise
may be heard, followed by the release of smoke.
This smoke is not harmful and does not indicate a
fire. Care should be taken to not inhale it, as it may
cause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
Front air bags, along with the use of seat belts,
help to cushion the impact force on the face and
chest of the front occupants. They can help save
lives and reduce serious injuries. However, an
inflating front air bag may cause facial abrasions
or other injuries. Front air bags do not provide
restraint to the lower body.
Even with NISSAN Advanced Air Bags, seat
belts should be correctly worn and the driver and
front passenger seated upright as far as practical
away from the steering wheel or instrument
panel. The front air bags inflate quickly in order tohelp protect the front occupants. Because of this,
the force of the front air bag inflating can increase
the risk of injury if the occupant is too close to, or
is against, the front air bag module during infla-
tion.
The front air bags deflate quickly after a collision.
The front air bags operate only when the
ignition switch is in the ON position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.
