other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
.If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel once it judges
that the vehicle has come to a
standstill and sound a warning chime.
To prevent the vehicle from moving,
the driver must depress the brake
pedal.
.Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The vehicle-to-vehicle
distance control mode of the ICC
system may not be able to maintain
the selected distance between vehi-
cles (following distance) or selected
vehicle speed under some circum-
stances.
.The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, 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 system sensor
— On steep downhill roads (the
vehicle may go beyond the set
vehicle speed and frequent brak-
ing may result in overheating the
brakes)
— On repeated uphill and downhill
roads
— When traffic conditions make it
difficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
.In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. You
may need to control the distance
from other vehicles using the accel-
erator pedal. Always stay alert and
avoid using the ICC system when it is
not recommended in this 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 sensor generally detects the signals
returned from the vehicle ahead. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system may
not maintain the selected distance.
The following are some conditions in which
the sensor cannot detect the signals:
.When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
.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
limitation of the system. When the sensor
is covered with dirt or is obstructed, the
system will automatically be canceled. If the
sensor is covered with ice, a transparent or
translucent vinyl bag, etc., the ICC system
may not detect them. In these instances, the
vehicle-to-vehicle distance control mode
may not cancel and may not be able to
maintain the selected following distance

The DCA system is intended to assist the
driver in keeping a following distance from
the vehicle ahead traveling in the same lane
and direction.
If the radar sensor
detects a slower
moving vehicle ahead, the system will reduce
the vehicle speed to help assist the driver to
maintain a following distance.
The system automatically controls the throt-
tle and applies the brakes (up to approxi-
mately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) 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 depres-
sing the brake pedal to maintain a safe
vehicle distance if:
.The chime sounds.
.The vehicle ahead detection indicator
blinks.
.The driver assist system forward indica-
tor (orange) blinks.
The warning chime may not sound in some
cases when there is a short distance be-
tween 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 driver assist system forward indicator
(orange) blinks and the warning chime will
not sound when your vehicle approaches
vehicles that are parked or moving slowly.
NOTE:
The approach warning chime may soundand the driver assist system forward in-
dicator (orange) may blink when the radar
sensor detects objects on the side of the
vehicle or on the side of the road. This may
cause the DCA system to decelerate or
accelerate the vehicle. The radar 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).

DCA SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
of the DCA system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.This system will not adapt automati-
cally to road conditions. Do not use
the system on roads with sharp
curves, or on icy roads, in heavy rain
or in fog.
.The DCA system will not apply brake
control while the driver’s foot is on
the accelerator pedal.
.As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This sys-
tem does not correct careless, inat-
tentive or absent-minded driving, or
overcome poor visibility in rain, fog,
or other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing 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 ac-
cidents, 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 system sensor
— On steep downhill roads (fre-
quent braking may result in over-
heating the brakes)
— On repeated uphill and downhill
roads

faces will be longer than on normal
surfaces even with ABS. Stopping
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
vehicle 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. See
“Tire and loading information la-
bel” (P.10-13) of this manual.
— For detailed information, see
“Wheels and tires” (P.8-25) of
this manual.
The Anti-lock Braking System (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 eachwheel 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
ABS 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 dis-
tances.
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 mal-function, 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 you visit
an INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
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
properly. However, the pulsation may indi-
cate that road conditions are hazardous and
extra care is required while driving.

The Vehicle Dynamic Control (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 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 follow
the steered path despite increased
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 cannot
prevent loss of vehicle control in all driving
situations.
When the VDC system operates, the VDC
warning light
in the instrument panel
flashes so 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.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-19).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system automa-
tically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator light
illuminates to indicate 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 VDC warning light
flashes if
this occurs. All other VDC functions are off,
except for brake force distribution, and the
VDC warning light
will not flash. The
VDC system is automatically reset to on
when the ignition switch is placed in the OFF
position then back in the ON position.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-19) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-19).
The computer has a built-in diagnosticfeature 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 malfunction.
VDC operation is reduced when the INFINITI
Drive Mode Selector is used to select the
SPORT+ mode (if so equipped). The VDC
system may not operate in the same circum-
stances when compared to operation in the
standard mode. To help prevent accidents
drive carefully, avoid careless or dangerous
driving techniques and be especially careful
when driving and cornering on slippery
surfaces.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the four wheels depending
on the radius of the turn.
WARNING
.The VDC system is designed to help
the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving

same size and you are only replacing
2 of the 4 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 condi-
tions and cause an accident and
personal injury.
.If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. See “Wheels and tires” (P.10-
9) of this manual for wheel off-set
dimensions.
.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 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 you visit an INFINITI
retailer for these services..Replacing tires with those not origin-
ally specified by INFINITI 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 you contact an
INFINITI retailer for ID registration.
.Do not use a valve stem cap that is
not specified by INFINITI. 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 pres-
sure.
.Do not install a damaged or deformed
wheel or tire even if it has been
repaired. Such wheels or tires could
have structural damage and could fail
without warning.
.The use of retread tire is not recom-
mended.
.For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety
Information” (Canada) in the War-ranty Information Booklet.
Intelligent All-Wheel Drive (AWD)
models
CAUTION
.Always use tires of the same type,
size, brand, construction (bias, bias-
belted or radial), and tread pattern
on all four wheels. Failure to do so
may result in a circumference differ-
ence between tires on the front and
rear axles which will cause excessive
tire wear and may damage the trans-
mission, transfer case and differential
gears.
.ONLY use spare tires specified for
the Intelligent AWD model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
you visit an INFINITI retailer for this service.

Wheel balance
Unbalanced wheels may affect vehicle hand-
ling 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 performed
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 Information” (Canada) in
the INFINITI Warranty Information Booklet.
Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.
Emergency tire puncture repair kit
(if so equipped)
The emergency tire puncture repair kit
(Emergency Tire Sealant) is supplied with
the vehicle instead of a spare tire. It can be
used to temporarily repair minor tire punc-
tures. If possible, have the vehicle towed to a
facility that can repair or replace the flat tire.
Using the emergency tire puncture repair kit
may cause a malfunction of the tire pressure
sensor and cause the low tire pressure
warning light to illuminate.See “Flat tire” (P.6-3) for more details.
JACKING UP THE VEHICLE AND
REPLACING TIRES
This section contains the information about
the vehicle jack-up procedures and the tire
replacement.
NOTE:
Jacking tools are not equipped as standard
with this vehicle. It is recommended you
contact an INFINITI retailer about acquiring
the tools.
For models with run-flat tires, you can
continue driving to a safe location even if
they are punctured. (See “Run-flat tires”
(P.6-4) and “Run-flat tires” (P.8-32).)
For models with the emergency tire punc-
ture repair kit, you can temporarily fix a
minor tire puncture using it. (See “Repairing
a flat tire (for models with emergency tire
puncture repair kit)” (P.6-5).)
WARNING
.Make sure the parking brake is
securely applied and the transmission
into the P (Park) position.
.Never change tires when the vehicle
is on a slope, ice or slippery areas.This is hazardous.
.Never change tires if oncoming traf-
fic is close to your vehicle. Wait for
professional road assistance.
