DCA SYSTEM LIMITATIONS
WARNING
∙ This system is only an aid to assist the driver and is not a collision warning or
avoidance device. It is the driver’s re-
sponsibility to stay alert, drive safely and
be in control of the vehicle at all times.
∙ This system will not adapt automatically to road conditions.
∙ As there is a performance limit to the dis- tance control function, never rely solely
on the DCA system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding circumstances in order to main-
tain a safe distance between vehicles.
∙ The system may not detect the vehicle in front of you in certain road or weather
conditions. To avoid accidents, never use
the DCA system under the following
conditions:
– On roads with 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 sensor area of the front bumper
– On steep downhill roads (frequent braking may result in overheating the
brakes)
– On repeated uphill and downhill roads
∙ Do not use the DCA system if you are towing a trailer. The system may not de-
tect a vehicle ahead.
∙ In some road or traffic conditions, a ve- hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to con-
trol the distance from other vehicles us-
ing the accelerator pedal. Always stay
alert and avoid using the DCA system
where not recommended in this warning
section.
5-104Starting and driving

The following are some conditions in which
the sensor cannot detect the signals:∙ When the reflector of the vehicle ahead is covered with dirt, snow and road spray
∙ When dense exhaust or other smoke (black smoke) from vehicles reduces the
sensor’s detection
∙ When excessively heavy baggage is loaded in the rear seat or the luggage
room of your vehicle
The DCA system is designed to automatically
check the sensor’s operation. When the front
bumper area around the distance sensor is
covered with dirt or is obstructed, the system
will automatically cancel. If the front bumper
area of the distance sensor is covered with
ice, a transparent or translucent vinyl bag,
etc., the DCA system may not detect them. In
these instances, the vehicle-to-vehicle dis-
tance control mode may not cancel and may
not be able to maintain the selected following
distance from the vehicle ahead. Be sure to
check and clean the front bumper area
around the distance sensor regularly. The DCA system is designed to help assist the
driver to maintain a following distance from
the vehicle ahead. The system will decelerate
as necessary and if the vehicle ahead comes
to a stop, the vehicle decelerates to a stand-
still. However, the DCA system can only ap-
ply up to 40% of the vehicle’s total braking
power. If a vehicle moves into the traveling
lane ahead or if a vehicle traveling ahead
rapidly decelerates, the distance between ve-
hicles may become closer because the DCA
system cannot decelerate the vehicle quickly
enough. If this occurs, the DCA system will
sound a warning chime and blink the system
display to notify the driver to take necessary
action.
For additional information, refer to “Ap-
proach warning” in this section.
This system only brakes and moves the accel-
erator pedal upward to help assist the driver
to maintain a following distance from the
vehicle ahead. Acceleration should be oper-
ated by the driver.
The DCA system does not control vehicle
speed or warn you when you approach sta-
tionary and slow moving vehicles. You must
pay attention to vehicle operation to main-
tain proper distance from vehicles ahead.
Starting and driving5-105

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the sensor may
detect vehicles in a different lane, or may
temporarily not detect a vehicle traveling
ahead. This may cause the system to work
inappropriately.
The detection of vehicles may also be af-
fected by vehicle operation (steering maneu-
ver or traveling position in the lane, etc.) or
vehicle condition.If this occurs, the system
may warn you by blinking the system indica-
tor and sounding the chime unexpectedly.
You will have to manually control the proper distance away from the vehicle traveling
ahead.
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 DCA 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 increasing
∙ When a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked
or moving slowly.

– When installing a spare tire, make surethat it is the proper size and type as
specified on the Tire and Loading In-
formation label. For additional infor-
mation, refer to “Tire and Loading In-
formation 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
rotation speed at each wheel and varies the
brake fluid pressure to prevent 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 pre-
vent 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) 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 malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then op-
erates normally but without anti-lock assis-
tance.
If the ABS warning light illuminates during
the self-test or while driving, have the vehicle
checked. It is recommended that you visit an
INFINITI retailer for this service.
Normal operation
The Anti-lock Braking System (ABS) operates
at speeds above3-6mph(5-10km/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 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 prop-
erly. However, the pulsation may indicate
that road conditions are hazardous 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 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. Un-
der certain driving conditions, the VDC sys-
tem 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 out- put 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 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 main-
tain control of the vehicle, but it cannot pre-
vent loss of vehicle control in all driving situ-
ations.
When the VDC system operates, the
indicator light 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 indi-
cates that the VDC system is working
properly.
∙ Adjust your speed and driving to the road conditions.
For additional information, refer to “Slip indi-
cator light” and ”Vehicle Dynamic Control
(VDC) OFF indicator light” in the ”Instruments
and controls” section of this manual.
If a malfunction occurs in the system,
the
andindicator lights come on
in the instrument panel. The VDC system au-
tomatically turns off when these indicator
lights are on.
The VDC OFF switch is used to turn off the
VDC system. The
indicator light and
the FEB with Pedestrian Detection system
warning light illuminate to indicate the VDC
system is off.
When the VDC OFF 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 light flashes if this occurs. All other VDC functions are off and
the
indicator light will not flash.
The VDC system is automatically reset to on
when the ignition switch is placed in the OFF
position then back to the ON position.
The computer has a built-in diagnostic fea-
ture that tests the system each time you start
the engine and move the vehicle forward or in
reverse at a slow speed. When the self-test
occurs, you may hear a clunk noise and/or
feel a pulsation in the brake pedal. This is
normal and is not an indication of a malfunc-
tion.
WARNING
∙ The VDC system is designed to help the driver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-140Starting and driving

When the vehicle is stopped on a hill, the hill
start assist system automatically keeps the
brakes applied to help prevent the vehicle
from rolling backward in the time it takes the
driver to release the brake pedal and apply
the accelerator.
The hill start assist system will operate auto-
matically under the following conditions:∙ The transmission is shifted to a forward or reverse gear.
∙ The vehicle is stopped completely on a hill by applying the brake. The maximum
holding time is 2 seconds. After 2 sec-
onds the vehicle will begin to roll back and
the hill start assist system will stop oper-
ating completely.
The hill start assist system will not operate
when the shift lever is placed in the N (Neu-
tral) or P (Park) position or on a flat and level
road. The sonar system sounds a tone to inform the
driver of obstacles near the bumper.
When the sonar system is turned on, the
sonar view will automatically appear in the
center display when the camera is activated.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar system
could result in serious injury or death.
∙ The sonar system is not a replacement for
proper driving procedures and is not de-
signed to prevent contact with vehicles
or objects. ∙ The driver is always responsible for
safety during parking and other maneu-
vers. Always look around and check that
it is safe to do so before parking.
∙ This function is designed as an aid to the driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inaccu-
rate measurement of obstacles or false
alarm.
CAUTION
∙ Excessive noise (such as audio system volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
∙ Keep the sonar sensors (located on the bumper fascias) free from snow, ice and
large accumulations of dirt. Do not clean
the sensors with sharp objects. If the sen-
sors are covered, the accuracy of the so-
nar function will be diminished.

SONAR LIMITATIONS
WARNING
Listed below are the system limitations for
the sonar system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
∙ Read and understand the limitations of the sonar system as contained in this sec-
tion. Inclement weather may affect the
function of the sonar system; this may
include reduced performance or a false
activation.
∙ The system is deactivated at speeds above 6 mph (10 km/h). It is reactivated
at lower speeds.
∙ Inclement weather or ultrasonic sources such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem; this may include reduced perfor-
mance or a false activation.
∙ The system is not designed to prevent contact with small or moving objects. Al-
ways move slowly. The system will not
detect small objects below the bumper or
on the ground. ∙ The system may not detect the following
objects: fluffy objects such as snow,
cloth, cotton, glass-wool, etc.; thin ob-
jects such as rope, wire and chain, etc.; or
wedge-shaped objects.
∙ The system may not detect objects at speeds above 3 mph (5 km/h) and may
not detect certain angular or moving
objects.
SYSTEM TEMPORARILY
UNAVAILABLE
When sonar blockage is detected, the system
will be deactivated automatically.
The system is not available until the condi-
tions no longer exist.
The sonar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog. The blocked condition
may also be caused by objects such as ice,
frost or dirt obstructing the sonar sensors.
Action to take:
When the above conditions no longer exist,
the system will resume automatically.
5-146Starting and driving

∙ If the low tire pressure warning light illu-minates 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 injury.
Check the tire pressure for all four tires.
Adjust the tire pressure to the recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
OFF. If the light still illuminates while
driving after adjusting the tire pressure,
a tire may be flat or the TPMS may be
malfunctioning. If you have a flat tire, re-
place it with a spare tire as soon as pos-
sible, If no tire is flat and all tires are
properly inflated, have the vehicle
checked. It is recommended that you visit
an INFINITI retailer for this service. ∙ When replacing a wheel without TPMS
such as the spare tire, 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
an INFINITI retailer for these services.
∙ Replacing tires with those not originally specified by INFINITI 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
below:
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
personnel that you need assistance.
6. Have all passengers get out of the ve- hicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
∙ Make sure the parking brake is securelyapplied and the Continuously Variable
Transmission (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.
