NOTE:
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user’s author-
ity to operate the equipment.
For Canada:
This device complies with Industry
Canada licence-exempt RSS standard(s).
Operation is subject to the following two
conditions: (1) this device may not cause
interference, and (2) this device must ac-
cept any interference, including interfer-
ence that may cause undesired opera-
tion of the device.
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 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 po-
sition. 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 than
approximately 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 indi-
cates that the Easy-Fill Tire Alert is
not operating. ∙ The TPMS will not activate the Easy-
Fill Tire Alert under the following con-
ditions:
– If there is interference from an exter- nal 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 sen- sor is low.
∙ If the Easy-Fill Tire Alert does not op- erate 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.
5-6Starting and driving

∙ Push and release the ACCEL/RESswitch. Each time you do this, the set
speed increases by about 1 mph
(1.6 km/h).
To reset at a slower cruising speed, use
one of the following three methods:
∙ Lightly tap the brake pedal. When the vehicle attains the desired speed, push
the COAST/SET switch and release it.
∙ Push and hold the COAST/SET switch. Release the switch when the vehicle
slows to the desired speed.
∙ Push and release the COAST/SET switch. Each time you do this, the set
speed decreases by about 1 mph
(1.6 km/h).
To resume the preset speed, push and
release the ACCEL/RES switch. The vehicle
returns to the last set cruising speed when
the vehicle speed is over 25 mph (40 km/h).WARNING
Failure to follow the warnings and in-
structions for proper use of the ICC sys-
tem could result in serious injury or
death.
∙ The ICC system is only an aid to assist the driver and is not a collision warn-
ing 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.
∙ Always observe posted speed limits and do not set the speed over them.
∙ Always drive carefully and attentively when using the ICC system. Read and
understand the Owner’s Manual thor-
oughly before using the ICC system.
To avoid serious injury or death, do
not rely on the system to prevent ac-
cidents or to control the vehicle’s
speed in emergency situations. Do
not use the ICC system except in ap-
propriate road and traffic conditions. The ICC system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and di-
rection.
The ICC system uses a radar sensor
A
located on the front of the vehicle to detect
vehicles traveling ahead.
If the radar sensor detects a slower moving
vehicle ahead, the system will reduce the
vehicle speed so that your vehicle follows
the vehicle in front at the selected distance.
The detection range of the sensor is ap-
proximately 390 f t (120 m) ahead.

Distance Approximate distance at60 mph (100 km/h) [f t (m)]
1. Long 200 (60)
2. Middle 150 (45)
3. Short 90 (30)
∙ The distance to the vehicle ahead will change according to the vehicle speed.
The higher the vehicle speed, the longer
the distance.
∙ If the engine is stopped, the set distance becomes “long.” (Each time the engine
is started, the initial setting becomes
“long.”)
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the sys-
tem warns the driver with the chime and
ICC system display. Decelerate by depress-
ing the brake pedal to maintain a safe ve-
hicle 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 ve-
hicles is increasing.
∙ 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, overriding 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 ve-
hicle.
Also, the sensor sensitivity can be af-
fected by vehicle operation (steering
maneuver or driving position in the lane)
or traffic or vehicle condition (for ex-
ample, if a vehicle is being driven with
some damage).

∙ The system may not detect the ve-hicle in front of you in certain road or
weather conditions. To avoid acci-
dents, 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 ve- hicle may go beyond the set ve-
hicle speed and frequent braking
may result in overheating the
brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it dif- ficult to keep a proper distance be-
tween vehicles because of fre-
quent 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 follow-
ing 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 ve-
hicle ahead and the system may not oper-
ate 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 automati-
cally check the sensor’s operation within
the limitations of the system.
The detection zone of the ICC sensor is
limited. A vehicle ahead must be in the de-
tection zone for the vehicle-to-vehicle dis-
tance detection mode to maintain the se-
lected distance from the vehicle ahead.
A vehicle ahead may move outside of the
detection 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 entering 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 dis-
tance away from the vehicle traveling
ahead.

AEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the AEB system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The AEB 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 AEB
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 covering 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
AEB 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 slip- pery 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.

shoes and/or drums/rotors are replaced, in
order to assure the best braking performance.
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, butit cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances 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 vehicle in
front of you. Ultimately, the driver is
responsible for safety.
∙ Tire type and condition may also af- fect 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 ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer infor-
mation” 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 rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate 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 Anti-lock Braking System (ABS) in-
cludes 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 mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates 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 ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Starting and driving5-73

Normal operation
The Anti-lock Braking System (ABS) oper-
ates 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 applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion 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 op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional 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
driver’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 perform 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 func-
tion).
∙ Controls brake pressure at individual wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
– Understeer (vehicle tends to not fol- low the steered path despite in-
creased steering 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 can-
not prevent loss of vehicle control in all driv-
ing situations.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-74Starting and driving

∙ If the wheels are changed for any rea-son, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad/shoe wear. For additional infor-
mation on wheel-off set dimensions,
refer to “Wheels and tires” in the
“Technical and consumer informa-
tion” section of this manual.
∙ When replacing a wheel without the TPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN dealer
for this service.
∙ Replacing tires with those not origi- nally 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. Con-
tact 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
without warning.
∙ The use of retread tires is not recommended.
∙ For additional information regarding tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation 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 balanced 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 In-
formation” (Canada) in the Warranty
Information Booklet.
Care of wheels
∙ Wash the wheels when washing the ve- hicle 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.
