When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the speed
to maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway,
the ICC system will accelerate and maintain
the speed up to the set speed. Pay attention
to the driving operation to maintain control
of the vehicle as it accelerates to the set
speed.
The vehicle may not maintain the set speed
on winding or hilly roads. If this occurs, you
will have to manually control the vehicle
speed.
Normally when controlling the distance to avehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is
required for a lane change. Depress the
brake pedal when deceleration is required
to maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when using
the ICC system.

Vehicle-to-vehicle distance control
mode switches
The system is operated by a MAIN switch
and four control switches, all mounted on
the steering wheel.
1. RES+ operation:
Resumes set speed or increases speed
incrementally.
2. SET- operation: Sets desired cruise speed, reduces speed
incrementally.
3. DISTANCE switch: Changes the vehicle’s following distance:

WAF0754X
To set cruising speed,accelerate your
vehicle to the desired speed, push down
the control switch to SET- and release it.
(The color of the cruise indicator changes to
green and set vehicle speed indicator comes
on.) Take your foot off the accelerator pedal.
Your vehicle will maintain the set speed.
. To pass another vehicle, depress the
accelerator pedal. When you release the
pedal, the vehicle will return to the
previously set speed.
. The vehicle may not maintain the set
speed when going up or down steep hills.
If this happens, manually maintain vehi-
cle speed. To cancel the preset speed,
use any of the
following methods:
. Push the CANCEL switch. The set vehicle
speed indicator will turn off.
. Tap the brake pedal. The set vehicle
speed indicator will turn off.
. Turn the MAIN switch off. Both the
MAIN switch indicator and set vehicle
speed indicator will turn off.
To reset at a faster cruising speed, use one
of the following three methods:
. Depress the accelerator pedal. When the
vehicle attains the desired speed, push
down the control switch to SET- and
release it.
. Push up and hold the control switch to
RES+. When the vehicle attains the
speed you desire, release the switch.
. Push up the control switch to RES+ and
then quickly release it. Each time you do
this, the set speed will increase 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
down the control switch to SET- and
release it.
. Push down and hold the control switch to
SET-. Release the switch when the
vehicle slows down to the desired speed. .
Push down the control switch to SET-
and then quickly release it. Each time you
do this, the set speed will decrease by
about 1 MPH (1.6 km/h).
To resume the preset speed, push up the
control switch to RES+ and release it. The
vehicle will resume the last set cruising speed
when the vehicle speed is over 25 MPH (40
km/h).
System temporarily unavailable
Under the following condition, a chime will
sound and the system control is automati-
cally canceled.
. When the vehicle slows down more than
8 MPH (13 km/h) below the set speed
. When the shift lever is shifted to the N
(Neutral) position
. When the parking brake is applied
. When the VDC (including the traction
control system) operates
. When a wheel slips

applies harder braking automatically.
While the FEB with Pedestrian Detection
system is operating, you may hear the sound
of brake operation. This is normal and
indicates that the FEB with Pedestrian
Detection system is operating properly.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the FEB with
Pedestrian Detection system.
Depending on vehicle speed and distance to
the vehicle or pedestrian ahead, as well as
driving and roadway conditions, the system
may help the driver avoid a forward collision
or may help mitigate the consequences of a
collision should one be unavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the FEB with Pe-
destrian Detection system will function later
or will not function.
The automatic braking will cease under the
following conditions:
.When the steering wheel is turned as far
as necessary to avoid a collision.
. When the accelerator pedal is depressed.
. When there is no longer a vehicle,
pedestrian detected ahead.
If the FEB with Pedestrian Detection system
has stopped the vehicle, the vehicle will
remain at a standstill for approximately 2 seconds before the brakes are released.
When the brake pedal is depressed while the
brake is applied by the system, you may feel
the pedal effort is changed and may hear a
sound and vibration noise. This is normal and
does not indicate a malfunction. In addition,
the braking force can be increased by adding
the pedal effort.

tions could result in serious injury or
death.
.The FEB with Pedestrian Detection
system cannot detect all vehicles or
pedestrians under all conditions.
. The FEB with Pedestrian Detection
system does not detect the following:
— Pedestrians that are small (for example, children), in a sitting
position, operating toys/skate-
boards, on scooters or in wheel-
chairs, or not in an upright
standing or walking position.
— Animals of any size.
— Obstacles (for example, cargo or debris) on the roadway or road-
side.
— Oncoming or crossing vehicles.
— Vehicles where the tires are diffi- cult to see or the shape of the rear
of the vehicle is unclear or ob-
structed.
— Parked vehicles.
. The FEB with Pedestrian Detection
system has some performance limita-
tions.
— If a stationary vehicle is in the vehicle’s path, the system will not function when the vehicle ap-
proaches the stationary vehicle
at speeds over approximately 50
MPH (80 km/h).
— Pedestrian detection will not function when the vehicle is driven
at speeds over approximately 37
MPH (60 km/h) or below ap-
proximately 6 MPH (10 km/h).
. For pedestrians, the FEB with Pedes-
trian Detection system will not issue
the first warning.
. The FEB with Pedestrian Detection
system may not function properly or
detect a vehicle or pedestrian ahead
in the following conditions:
— In poor visibility conditions (such as rain, snow, fog, dust storms,
sand storms, smoke, and road
spray from other vehicles).
— If dirt, ice, snow, fog or other material is covering the radar
sensor area or camera area of
the windshield.
— If strong light (for example, sun- light or high beams) enters the
front camera or a sudden change
in brightness occurs (for example,
entering a tunnel or driving in
lightning). — In dark or dimly lit conditions,
such as at night or in tunnels,
including cases where your vehi-
cle’s headlights are off or dim, or
the tail lights of the vehicle ahead
are off.
— When the direction of the camera is misaligned.
— When driving on a steep downhill slope, on roads with sharp curves,
and/or bumpy or dirt roads.
— If there is interference by other radar sources.
— When your vehicle’s position or movement is changed quickly or
significantly (for example, lane
change, turning vehicle, abrupt
steering, sudden acceleration or
deceleration).
— When your vehicle or the vehicle or pedestrian ahead moves quickly
or significantly such that the sys-
tem cannot detect and react in
time (for example, pedestrian
moving quickly toward the vehicle
at close range, vehicle cutting in,
changing lanes, making a turn,
steering abruptly, sudden accel-
eration or deceleration).

The 4WD shift switch is used to select the
4WD mode depending on the driving condi-
tions. There are 3 types of drive modes
available, AUTO, 4HI and 4LO.
The 4WD shift switch electronically controls
the transfer case operation. Rotate the
switch to move between each mode, AUTO,
4H and 4L.
You must depress the 4WD shift switch to
select 4L, and the vehicle MUST be sta-
tionary and the shift lever in the N (Neutral)
position when changing into or out of 4L.
WARNING
.When parking, apply the parking
brake before stopping the engine
and make sure that the 4WD shift
indicator is on and the ATP warning
light turns off. Otherwise, the vehicle
could unexpectedly move even if the
automatic transmission is in the P
(Park) position.
. The 4LO and 4HI indicators must
stop blinking and the 4LO or 4HI
indicator must remain illuminated or
turn off before shifting the transmis-
sion into gear. If the shift lever is
shifted from the N (Neutral) position
to any other gear while the 4LO and
4HI indicators are blinking alter- nately, the vehicle may move unex-
pectedly.
CAUTION
.
Never shift the 4WD shift switch
between 4L and 4H while driving.
. The 4HI position provides greater
traction. Avoid excessive speed, as it
will cause increased fuel consumption
and higher oil temperatures, and
could damage drivetrain component.
Speeds over 62 MPH (100 km/h) in
4HI is not recommended.
. The 4LO position provides maximum
traction. Avoid raising vehicle speed
excessively, as the maximum speed is
approximately 31 MPH (50 km/h).
. When driving straight, shift the 4WD
shift switch to the AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or rever-
sing.
. Do not shift the 4WD shift switch
(between AUTO and 4H) while driv-
ing on steep downhill grades. Use the
engine brake and low automatic
transmission gears for engine brak-
ing. .
Do not operate the 4WD shift switch
(between AUTO and 4H) with the
rear wheels spinning.
. Do not drive on dry hard surface
roads in the 4HI or 4LO position.
Driving on dry hard surfaces in 4HI or
4LO may cause unnecessary noise
and tire wear. INFINITI recommends
driving in the AUTO position under
these conditions.
. The 4WD transfer case may not be
shifted between 4HI and 4LO at low
ambient temperatures and the 4LO
and 4HI indicators may blink even
when the 4WD shift switch is shifted.
After driving for a while you can
change the 4WD shift switch be-
tween 4H and 4L.
When driving on rough roads,
. Drive carefully according to the road
surface conditions.
When the vehicle is stuck,
. Place stones or wooden blocks under the
tires to free the vehicle.
. Set the 4WD shift switch to 4H or 4L.
. If it is difficult to free the vehicle, repeat
forward and backward movement to
increase the movement.

.If the vehicle is stuck deep in mud, tire
chains may be effective.
CAUTION
. Do not spin the tires excessively.
Tires will sink deep into the mud,
making it difficult to free the vehicle.
. Avoid shifting gears with the engine
running at high speeds as this may
cause malfunction.

4WD SHIFT SWITCH
.Shift the 4WD shift switch to either the
AUTO, 4H or 4L position, depending on
driving conditions.
. With the switch set to the AUTO posi-
tion, distribution of torque to the front
and rear wheels changes automatically,
depending on road conditions encoun-
tered [ratio; 0 : 100 (2WD) ?50 : 50
(4WD)]. This results in improved driving
stability.
. When the vehicle is stopped after mak-
ing a turn, you may feel a slight jolt after
the shift lever is shifted to N (Neutral) or
P (Park) position. This occurs because
the transfer clutch is released and not because of a malfunction.
CAUTION
.
When driving straight, shift the 4WD
shift switch to the AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or rever-
sing. If the 4WD shift switch is
operated while making a turn, accel-
erating or decelerating or if the
ignition switch is placed in the OFF
position while in the AUTO, 4H or 4L,
you may feel a jolt. This is not a
malfunction.
. Do not shift the 4WD shift switch
while driving on steep downhill
grades. Use the engine brake and
low automatic transmission gears
for engine braking.
. Do not operate the 4WD shift switch
with the rear wheels spinning.
. Before placing the 4WD shift switch
in the 4H position from AUTO,
ensure the vehicle speed is less than
62 MPH (100 km/h). Failure to do so
can damage the 4WD system.
. Never shift the 4WD shift switch
between 4L and 4H while driving.

5-122Starting and driving
If any malfunction occurs in the 4WD system
when the ignition switch is placed in the ON
position, the 4WD warning light will either
remain illuminated or blink.
If the 4WD warning light comes on, the
4WD shift indicator turns off.
High-temperature transfer case oil makes
the 4WD warning light blink rapidly (about
twice per second). If the warning light blinks
rapidly during operation, stop the vehicle in a
safe place immediately. Then if the light
turns off after a while, you can continue
driving.
A large difference between the diameters of
front and rear wheels will make the 4WD
warning light blink slowly (about once per
two seconds). Change the 4WD shift switch
to AUTO and do not drive fast.
CAUTION
.If the 4WD warning light comes on or
blinks slowly during operation or
rapidly after stopping the vehicle for
a while, have your vehicle checked as
soon as possible. It is recommended
you visit an INFINITI retailer for this
service.
. Shifting between 4HI and 4LO is not
recommended when the 4WD warn- ing light turns on.
. When the 4WD warning light comes
on, the 2WD mode may be engaged
even if the 4WD shift switch is in
AUTO or 4H. Be especially careful
when driving. If corresponding parts
are malfunctioning, the 4WD mode
will not be engaged even if the 4WD
shift switch is shifted.
. Do not drive the vehicle in the 4HI or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces
in 4HI or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD warning light turns on
when driving on dry hard surface
roads:
— in the AUTO or 4HI position, shift the 4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmission
shift lever to the N (Neutral)
position and shift the 4WD shift
switch to AUTO.
. If the 4WD warning light is still on
after the above operation, have your
vehicle checked as soon as possible. It
is recommended you visit an INFINITI
retailer for this service. .
The transfer case may be damaged if
you continue driving with the warn-
ing light blinking.

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.
MCE0001A
Blocking wheels
Place suitable blocksat both the front and
back of the wheel diagonally opposite the
flat tire to prevent the vehicle from moving
when it is jacked up.
WARNING
Be sure to block the wheel as the vehicle
may move and result in personal injury.

6-8In case of emergency
dropping of the wheel while driving.
Lower the wheel on the ground again,
and make sure that the hanging plate is
properly set. Hang the wheel again and
make sure that the wheel is held hor-
izontally, then store the wheel.
Jacking up the vehicle and removing
the damaged tire
WARNING
.Never get under the vehicle while it is
supported only by the jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Use only the jack provided with your
vehicle to lift the vehicle. Do not use
the jack provided with your vehicle on
other vehicles. The jack is designed
for lifting only your vehicle during a
tire change.
. Use the correct jack-up points. Never
use any other part of the vehicle for
jack support.
. Never jack up the vehicle more than
necessary.
. Never use blocks on or under the jack. .
Do not start or run the engine while
vehicle is on the jack, as it may cause
the vehicle to move. This is especially
true for vehicles with limited slip
differentials.
. Do not allow passengers to stay in
the vehicle while it is on the jack.
Carefully read the caution label attached to
the jack body and the following instruc-
tions.SCE0875
