TPMS with Easy-Fill Tire Alert (if so
equipped)
When adding air to an under-inflated tire, the
TPMS with Easy-Fill Tire Alert provides visual and
audible signals outside the vehicle to help you
inflate the tires to the recommended COLD tire
pressure.
Vehicle set-up:1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shift lever into the P (Park) position (if so
equipped) . 3. Place the ignition switch to the ON position.
Do not start the engine.
Operation: 1. Add air to the tire.
2. After a few seconds, the hazard indicators will start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard indica-
tors stop flashing.
4. Perform the above steps for each tire. ●If the tire is over-inflated more than ap-
proximately 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 pres-
sure, the horn beeps once.
● If the hazard indicator does not flash
within approximately 15 seconds after
starting to inflate the tire, it indicates that
the Easy-Fill Tire Alert is not operating.
● The TPMS will not activate the Easy-Fill
Tire Alert under the following conditions:
– If there is interference from an external device or transmitter. – The air pressure from the inflation device
is not sufficient to inflate the tire.
– There is a malfunction in the TPMS sys- tem.
– There is a malfunction in the horn or haz- ard indicators.
– The identification code of the tire’s pres- sure sensor is not registered to the sys-
tem.
– The battery of the tire pressure sensor is low.
● If the Easy-Fill Tire Alert does not operate
due to TPMS interference, move the ve-
hicle about 3 ft (1 m) backward or forward
and try again.
If the Easy-Fill Tire Alert is not working, use a tire
pressure gauge.
5-6Starting and driving

Approach warning
If your vehicle comes closer to the vehicle ahead
due to rapid deceleration of that vehicle or if
another vehicle cuts in, the system warns the
driver with the chime and ICC system display.
Decelerate by depressing the brake pedal to
maintain a safe vehicle distance if:● The chime sounds.
● The vehicle ahead detection indicator blinks.
The warning chime may not sound in some cases
when there is a short distance between vehicles.
Some examples are: ● When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing.
● When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing.
● When a vehicle cuts in near your vehicle.
The warning chime will not sound when: ● The vehicle approaches other vehicles that
are parked or moving slowly.
● The accelerator pedal is depressed, overrid-
ing the system. NOTE:
The approach warning chime may sound
and the system display may blink when the
ICC sensor detects objects on the side of
the vehicle or on the side of the road. This
may cause the ICC system to decelerate or
accelerate the vehicle. The ICC sensor may
detect these objects when the vehicle is
driven on winding roads, narrow roads, hilly
roads, or when entering or exiting a curve.
In these cases you will have to manually
control the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condition
(for example, if a vehicle is being driven with some
damage) .
Starting and driving5-55

●The system may not detect the vehicle
in front of you in certain road or weather
conditions. To avoid accidents, never
use the ICC system under the following
conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources. ●
Do not use the ICC system if you are
towing a trailer. The system may not
detect a vehicle ahead.
● In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The radar sensor will not detect the following
objects: ● Stationary and slow moving vehicles
● Pedestrians or objects in the roadway
● Oncoming vehicles in the same lane
● Motorcycles traveling offset in the travel lane
The following are some conditions in which the
sensor cannot properly detect a vehicle ahead
and the system may not operate properly: ● When snow or road spray from traveling
vehicles reduces the sensor’s detection.
● When excessively heavy baggage is loaded
in the rear seat or the trunk of your vehicle. The ICC system is designed to automatically
check the sensor’s operation within the limita-
tions of the system.
The detection zone of the ICC sensor is limited. A
vehicle ahead must be in the detection zone for
the vehicle-to-vehicle distance detection mode
to maintain the selected distance from the vehicle
ahead.
A vehicle ahead may move outside of the detec-
tion zone due to its position within the same lane
of travel. Motorcycles may not be detected in the
same lane ahead if they are traveling offset from
the centerline of the lane. A vehicle that is enter-
ing the lane ahead may not be detected until the
vehicle has completely moved into the lane.
If this occurs, the ICC system may warn you
by blinking the system indicator and
sounding the chime. The driver may have to
manually control the proper distance away
from vehicle traveling ahead.

TURNING THE FEB SYSTEM
ON/OFF
Perform the following steps to turn the FEB sys-
tems ON or OFF.1. Press the
button until “Settings” dis-
plays in the vehicle information display. Use
the
button to select “Driver Assis-
tance.” Then press the ENTER button.
2. Select “Driving Aids” and press the ENTER button.
3. Select “Emergency Brake” and press the ENTER button.
When the FEB system is turned off, the FEB
system warning light illuminates.
NOTE:
● The FEB system will be automatically turned
on when the engine is restarted.
FEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the FEB system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death. ●
The FEB system cannot detect all ve-
hicles under all conditions.
● The radar sensor does not detect the
following objects:
– Pedestrians, animals or obstacles in the roadway.
– Oncoming vehicles.
– Crossing vehicles.
● The radar sensor has some perfor-
mance limitations. If a stationary ve-
hicle is in the vehicle’s path, the FEB
system will not function when the ve-
hicle is driven at speeds over approxi-
mately 50 mph (80 km/h).
● The radar sensor may not detect a ve-
hicle ahead in the following conditions:
– Dirt, ice, snow or other material cov- ering the radar sensor.
– Interference by other radar sources.
– Snow or road spray from traveling vehicles.
– If the vehicle ahead is narrow (e.g. motorcycle) .
– When driving on a steep downhill slope or roads with sharp curves. ●
In some road or traffic conditions, the
FEB system may unexpectedly apply
partial braking. When acceleration is
necessary, continue to depress the ac-
celerator pedal to override the system.
● Braking distances increase on slippery
surfaces.
● The system is designed to automatically
check the sensor’s functionality, within
certain limitations. The system may not
detect some forms of obstructions of
the sensor area such as ice, snow, stick-
ers, 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.
Starting and driving5-65

This procedure is described in the vehicle service
manual. It is recommended that you visit a
NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping distances may also be longer on
rough, gravel or snow covered roads, or
if you are using tire chains. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels. – When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, refer to “Tire and Loading
Information label” in the “Technical
and consumer information” section
of this manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself” section of this manual.
The ABS controls the brakes so the wheels do
not lock during hard braking or when braking on
slippery surfaces. The system detects the rota-
tion speed at each wheel and varies the brake
fluid pressure to prevent each wheel from locking
and sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain steering
control and helps to minimize swerving and spin-
ning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
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.
Starting and driving5-73

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-
ers 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.
When the VDC system operates, the
indi-
cator in the instrument panel flashes to note the
following: ●
The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
● You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
● Adjust your speed and driving to the road
conditions.
For additional information, refer to “Slip indicator
light” and ”VDC off indicator light” in the ”Instru-
ments and controls” section.
If a malfunction occurs in the system, the
indicator light comes on in the instrument panel.
The VDC system automatically turns off when the
indicator light is off.
The VDC OFF switch is used to turn off the VDC
system. The
indicator illuminates to indi-
cate the VDC system is off.
When the VDC switch is used to turn off the
system, the VDC system still operates to prevent
one drive wheel from slipping by transferring
power to a non slipping drive wheel. The
indicator flashes if this occurs. All other VDC
functions are off and the
indicator will not
flash.

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
“CHECK TIRE PRES” (vehicles without a vehicle
information display) also appears in the trip com-
puter or the “Tire Pressure Low - Add Air” (ve-
hicles with a vehicle information display) 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 activate and warn you of it by the low
tire pressure warning light. This system will acti-
vate only when the vehicle is driven at speeds
above 16 mph (25 km/h). For additional informa-
tion, refer to “Warning lights, indicator lights and
audible reminders” in the “Instruments and con-
trols” section, and “Tire Pressure Monitoring Sys-
tem (TPMS)” in the “Starting and driving” sec-
tions 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.
● Since the spare tire is not equipped with
the TPMS, 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 approxi-
mately one minute. The light will remain
on after one minute. Have your tires
replaced 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.
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. Shift the manual transmission into R
(Reverse) , or the CVT into 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.

Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. For additional information,
refer to “Wheels and tires” in the “Technical and
consumer information” section of this manual.
WARNING
●The use of tires other than those recom-
mended or the mixed use of tires of
different brands, construction (bias,
bias-belted or radial) , or tread patterns
can adversely affect the ride, braking,
handling, Vehicle Dynamic Control
(VDC) system, ground clearance, body-
to-tire clearance, tire chain clearance,
speedometer calibration, headlight aim
and bumper height. Some of these ef-
fects may lead to accidents and could
result in serious personal injury.
● If your vehicle was originally equipped
with four tires that were the same size
and you are only replacing two of the
four tires, install the new tires on the
rear axle. Placing new tires on the front
axle may cause loss of vehicle control in
some driving conditions and cause an
accident and personal injury ●
If the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade ve-
hicle handling characteristics, affect the
VDC system and/or interference with
the brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear. For addi-
tional information on wheel off-set di-
mensions, refer to “Wheels and tires” in
the “Technical and consumer informa-
tion” section of this manual.
● 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
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit a NISSAN dealer for this service.
● Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS. ●
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.
