How to change the set distance to the
vehicle ahead
The distance to the vehicle ahead can be se-
lected at any time depending on the traffic con-
ditions.
Each time the DISTANCE switch is pressed, the
set distance will change to long, medium, short
and back to long again in that sequence.●
The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the dis-
tance.
● If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
● The CRUISE indicator light will appear in the
vehicle information display.
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 and set dis-
tance indicator blink.
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 the accelerator pedal is depressed,
overriding the system.
● 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.

NOTE:
The approach warning chime may sound
and the system display may blink when the
ICC sensor detects some reflectors
1
which are fitted on vehicles in other lanes
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 reflectors when the vehicle is driven
on winding roads, hilly roads or when en-
tering or exiting a curve. The ICC sensor
may also detect reflectors on narrow roads
or in road construction zones. 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 the traffic condition (for
example, if a vehicle is being driven with some
damage) .
Automatic cancellation
A chime sounds under the following conditions
and the control is automatically canceled.● When the vehicle speed falls below approxi-
mately 20 MPH (32 km/h)
● When the selector lever is shifted to a posi-
tion other than D (Drive) , 4, 3, 2, or 1, includ-
ing the manual shift mode ●
When the wiper is operated
● When the parking brake is applied
● When the VDC is turned off
● When the VDC operates

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.

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.

●When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
● For vehicles equipped with
, use 4H or
4L position only when necessary. Four-
wheel drive operation lowers fuel economy.
WARNING
● For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) , or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
CAUTION
● Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position, stop the vehicle, move the automatic transmission
shift selector to the N position and
shift the 4WD shift switch to 2WD
● If the warning light is still on after the
above operation, have your vehicle
checked by an INFINITI dealer as soon
as possible.
● The transfer case may be damaged if
you continue driving with the warning
light blinking.

The transfer case 4WD shift switch is used to
select either 2WD or 4WD depending on the
driving conditions. There are four types of drive
modes available, AUTO, 2WD, 4H and 4LO.
The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, 2WD, AUTO, 4H and
4LO.
You must push the switch in to select 4LO,
and the vehicle MUST be stationary and the
shift selector in the N position when chang-
ing into or out of 4LO.
WARNING
When parking, apply the parking brake
before stopping the engine and make sure
that the 4WD shift indicator light is on and
the ATP warning light goes off. Otherwise,
the vehicle could unexpectedly move even
if the automatic transmission is in the P
position.
CAUTION
●Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
● The 4H position provides greater trac-
tion. Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could
damage drivetrain components.
Speeds over 62 MPH (100 km/h) in 4H is
not recommended.
● The 4LO position provides maximum
power and traction. Avoid raising ve-
hicle speed excessively, as the maxi-
mum speed is approximately 31 MPH
(50 km/h) .
● When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or reversing.
● Do not shift the 4WD shift switch (be-
tween 2WD, AUTO and 4H) while driving
on steep downhill grades. Use the en-
gine brake and low automatic transmis-
sion gears (D1 or D2) for engine
braking. ●
Do not operate the 4WD shift switch
(between 2WD, AUTO and 4H) with the
rear wheels spinning.
● Do not drive on dry hard surface roads
in the 4H or 4LO position. Driving on dry
hard surfaces in 4H or 4LO may cause
unnecessary noise and tire wear.
INFINITI recommends driving in the
2WD or AUTO position under these
conditions.
● The 4WD transfer case may not be
shifted between 4H and 4LO at low am-
bient temperatures and the transfer
4LO position indicator light may blink
even when the 4WD shift switch is
shifted. After driving for a while you can
change the 4WD transfer case between
4H and 4LO.
When driving on rough roads, ● Set the 4WD shift switch to AUTO, 4H or
4LO.
● Drive carefully according to the road surface
conditions.
