●Do not impact the areas around the sensor.
Do not touch or remove the screw located
on the sensor. Doing so could cause failure
or malfunction. If the sensor is deformed due
to an accident, contact an INFINITI dealer.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.
CONVENTIONAL (FIXED SPEED)
CRUISE CONTROL MODE
This mode allows driving at a speed between 25
to 89 MPH (40 to 144 km/h) without keeping
your foot on the accelerator pedal.
WARNING
● In the conventional (fixed speed) cruise
control mode, a warning chime does
not sound to warn you if you are too
close to the vehicle ahead, as neither
the presence of the vehicle ahead nor
the vehicle-to-vehicle distance is
detected.
● Pay special attention to the distance
between your vehicle and the vehicle
ahead of you or a collision could occur. ●
Always confirm the setting in the Intel-
ligent Cruise Control system display.
● Do not use the conventional (fixed
speed) cruise control mode when driv-
ing under the following conditions:
– When it is not possible to keep the vehicle at a set speed.
– In heavy traffic or in traffic that varies in speed.
– On winding or hilly roads.
– On slippery roads (rain, snow, ice, etc.) .
– In very windy areas.
Doing so could cause a loss of vehicle
control and result in an accident.

BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the Brake Assist is acti-
vated, 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.
PREVIEW FUNCTION
When the Preview Function identifies the need to
apply emergency braking by sensing a vehicle
ahead in the same lane and the distance and
relative speed from it, it applies the brake pre-
pressure before the driver depresses the brake
pedal and helps improve brake response by re-
ducing pedal free play.●
This system will not operate when the ve-
hicle is moving at approximately 20 MPH (32
km/h) or less.
● The pre-pressure function ceases when the
following conditions are met:
a. When the driver depresses the accelerator pedal or the brake pedal.
b. If the driver does not operate the accelerator or brake pedal within approximately 1 second.
●The sensor will not detect:
a. Pedestrians or objects in the roadway
b. Oncoming vehicles in the same lane
c. Motorcycles or scooters traveling offset in the travel lane as illustrated

WARNING
●The Preview Function is only an aid to
assist the driver and is not a collision
warning or avoidance device. Although
the brake operation is controlled by the
system, it does not automatically decel-
erate the vehicle speed. It is the driver’s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
● As there is a performance limit to the
Preview Function, never rely solely on
this system. This system does not cor-
rect careless, inattentive or absent-
minded driving, or overcome poor vis-
ibility in rain, fog, or other bad weather.
Reduce the vehicle speed by depress-
ing the brake pedal, in order to maintain
a safe distance between vehicles.
● The system may not detect the vehicle
in front of you in certain road or weather
conditions. The Preview Function may
not operate properly under the follow-
ing conditions. The vehicle is still drive-
able under normal conditions and the
Brake Assist will operate.
– When rain, snow or dirt adhere to the system sensor. – When strong light (for example, at
sunrise or sunset) is directly shining
on the front of the vehicle.
– Winding or hilly roads may cause the sensor to temporarily not detect a
vehicle in the same lane or may de-
tect objects or vehicles in other
lanes.
– Vehicle position in the lane may cause the sensor to temporarily not
detect a vehicle in the same lane or
may detect objects or vehicles in
other lanes.
● When the Preview Function operates,
the brake pedal may move slightly and
may make a small noise. This is not a
system malfunction.
Warning light and display
When the Preview Function is not operating
properly, the chime sounds and the orange sys-
tem warning light will illuminate in the instrument
panel.
Action to take
If the warning light comes on, park the vehicle in a
safe place. Turn the engine off, restart the engine
and resume driving.

If the indicator stays on, it may indicate that
the Preview Function is malfunctioning
(the brake is operative) . Although the Ve-
hicle is still driveable under normal condi-
tions, have the vehicle checked at an
INFINITI dealer.
Sensor maintenance
The sensor for the Preview Function, is common
with Intelligent Cruise Control and is located
below the front bumper.
To keep the Preview Function operating properly,
be sure to observe the following:● Always keep the sensor clean. Wipe with a
soft cloth carefully so as not to damage
them.
● Do not impact the areas around the sensor.
Do not touch or disassemble the screw lo-
cated on the sensor. Doing so could cause
failure or malfunction. If the sensor installa-
tion part is deformed due to an accident,
contact an INFINITI dealer.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.
CAUTION
During the first 1,200 miles (2,000 km) ,
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy of
your new vehicle. Failure to follow these
recommendations may result in short-
ened engine life and reduced engine
performance.
● Avoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 rpm.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 miles
(800 km) . Your engine, axle or other parts
could be damaged. ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
● Avoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
● Use a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
● Avoid unnecessary engine idling.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the front wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
● Air conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.

This procedure is described in the vehicle service
manual and can be performed by an INFINITI
dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces 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 respon-
sible 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 label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section 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 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 slip-
pery 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.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) . The speed varies according to road
conditions.
When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
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.
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 by an INFINITI dealer.The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving situations, the
system will control braking and engine output to
help keep the vehicle on its steered path.
● When the Vehicle Dynamic Control (VDC)
system is operating, the slip indicator in the
instrument panel blinks.
● If the slip indicator blinks, the road condi-
tions may be slippery. Be sure to adjust your
speed and driving to these conditions. See
“Slip indicator light”, and “Vehicle Dynamic
Control (VDC) off indicator light” in the “In-
struments and controls” section.
● Indicator light
– If a malfunction occurs in the system, the SLIP and
indicator lights come on
in the instrument panel.
– If the 4WD transfer case is shifted into 4LO the
indicator light will come
on and the VDC system will be turned off.
See “Transfer case shifting procedures”
earlier in this section.
– As long as these indicator lights are on, the traction control function is canceled. If the vehicle is operated with the Vehicle Dy-
namic Control system off using the VDC OFF
switch, most VDC and Traction Control System
(TCS) functions will be turned off. The
SLIP
indicator will flash if wheel spin is detected. The
ABS will still operate with the VDC system off.
When the VDC system is operating, 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 prop-
erly.
The computer has a built in diagnostic feature
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.

●The system is designed as an aid to the
driver in detecting large stationary ob-
jects to help avoid damaging the ve-
hicle. The system will not detect small
objects below the bumper, and may not
detect objects close to the bumper or
on the ground.
● If your vehicle sustains damage to the
rear bumper fascia, leaving it mis-
aligned or bent, the sensing zone may
be altered causing inaccurate measure-
ment of obstacles or false alarms.
The Rear Sonar System (RSS) sounds a tone to
warn the driver of obstacles near the rear bumper
when the shift selector lever is in R (Reverse) .
The system may not detect objects at speeds
above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
The RSS detects obstacles up to 5.9 ft (1.8 m)
from the rear bumper with a decreased coverage
area at the outer corners of the bumper, (refer to
the illustration for approximate zone coverage
areas) . As you move closer to the obstacle, the
rate of the tone increases. When the obstacle is
less than 10 in (25.0 cm) away, the tone will
sound continuously. If the RSS detects a station-
ary or receding object further than 10 in. (25.0
cm) from the side of the vehicle, the tone will sound for only 3 seconds. Once the system de-
tects an object approaching, the tone will sound
again.
The RSS automatically turns on when the shift
selector is placed in R (Reverse) and the ignition
switch is placed in the ON position. The RSS
OFF switch on the instrument panel allows the
driver to turn the RSS on and off. To turn the RSS
off, the ignition switch must be placed in the ON
position. An indicator light on the switch will
illuminate when the system is turned off. If the
indicator light illuminates when the RSS is not
turned off, it may indicate a malfunction in the
RSS.
Keep the RSS sensors (located on the rear
bumper fascia) free from snow, ice and large
accumulations of dirt (do not clean the sensors
with sharp objects) . If the sensors are covered, it
will affect the accuracy of the RSS.
WARNING
●
Always look around before proceeding.
The FSS is not a substitute for proper
driving procedures.
● Read and understand the limitations of
the front sonar system as contained in
this section. Inclement weather may af-
fect the function of the FSS, this may
include reduced performance or a false
activation.
● This system is not designed to prevent
contact with small or moving objects.

● If your vehicle sustains damage to the
front bumper fascia, leaving it mis-

be altered causing inaccurate measure-
ment of obstacles or false alarms.
The Front Sonar System (FSS) sounds a tone to
warn the driver of obstacles near the front
bumper when the shift selector is in a forward
gear. The system may not detect objects at
speeds above 3 mph (5 km/h) and may not detect
certain angular or moving objects.
The FSS detects obstacles up to 3 ft (1.0 m) from
the front bumper with a decreased coverage area
at the outer corners of the bumper, (refer to the
illustration for approximate zone coverage areas) .
As you move closer to the obstacle, the rate of the
tone increases. When the obstacle is less than
12 in (30.0 cm) away, the tone will sound con-
tinuously. If the FSS detects a stationary or re-
ceding object further than 12 in (30.0 cm) from
the side of the vehicle, the tone will sound for only 3 seconds. Once the system detects an object
approaching, the tone will sound again.
The FSS automatically turns on when the shift
selector is placed in a forward gear and the
ignition switch is ON. The front and rear sonar
system off switch on the instrument panel allows
the driver to turn the FSS on and off. To turn the
FSS off, the ignition switch must be ON, and the
shift selector in D (Drive) . An indicator light on the
switch will illuminate when the system is turned
off. If the indicator light illuminates when the FSS
is not turned off, it may indicate a malfunction in
the FSS.
Keep the FSS sensors (located on the front
bumper fascia) free from snow, ice and large
accumulations of dirt (do not clean the sensors
with sharp objects) . If the sensors are covered, it
will affect the accuracy of the FSS.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply de-
icer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the key
hole or use the remote keyless entry keyfob.
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and do-it-yourself” section of this
