FEB WITH PEDESTRIAN DETEC-
TION SYSTEM OPERATION
The FEB with Pedestrian Detection system
will function when your vehicle is driven at
speeds above approximately 3 MPH (5
km/h).
For the pedestrian detection function, the
FEB with Pedestrian Detection system op-
erates at speeds between 6 – 37 MPH (10 –
60 km/h).
If a risk of a forward collision is detected, the
FEB with Pedestrian Detection system will
firstly provide the warning to the driver by
flashing the vehicle ahead detection indica-
tor (yellow) in the vehicle information display
and providing an audible alert. In addition,
the system applies partial braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the FEB
with Pedestrian Detection system detects
that there is still the possibility of a forward
collision, the system will automatically in-
crease the braking force.
If the driver does not take action, the FEB
with Pedestrian Detection system issues the
second visual (flashing) (red) and audible
warning. Then the system applies partial
braking.
If the risk of a collision becomes imminent,
the FEB with Pedestrian Detection system

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.

5-116Starting and driving
.Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-6).)
WARNING
. Do not attempt to raise two wheels
off the ground and shift the trans-
mission to any drive or reverse posi-
tion with the engine running. Doing
so may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage
or personal injury.
. Do not attempt to test a 4WD
equipped vehicle on a 2-wheel dy-
namometer or similar equipment even
if the other two wheels are raised off
the ground. Make sure you inform
test facility personnel that your ve-
hicle is equipped with 4WD before it
is placed on a dynamometer. Using
the wrong test equipment may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury.
CAUTION
.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 Four-Wheel Drive (4WD)
warning light turns on when driving
on dry hard surface roads:
— in the 4HI position, shift the 4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmission
lever to the N (Neutral) position
with the brake pedal depressed
and shift the 4WD shift switch to
AUTO.
If the 4WD warning light is still on
after the above operation, have
your vehicle checked. It is recom-
mended you visit an INFINITI
retailer for this service.
. The transfer case may be damaged if
you continue driving with the 4WD
warning light blinking.
See “On-pavement and off-road driving
precautions” (P.5-8) for other precautions
for offroad driving.
INCREASING FUEL ECONOMYINFINITI ALL-MODE 4WD®(if so equipped)

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.

.Engine idling speed is high while
warming up the engine. Be especially
careful when starting or driving on
slippery surfaces with the 4WD shift
switch in AUTO.

4WD SHIFT INDICATOR
The 4WD shift indicator is displayed in the
vehicle information display.
The indicator should turn off within a few
seconds after placing the ignition switch in
the ON position.
While the engine is running, the 4WD shift
indicator will illuminate the position selected
by the 4WD shift switch. (See the 4WD shift
procedure list shown in the “INFINITI all-
mode 4WD
®system” (P.5-117).) .
The 4WD shift indicator may blink while
shifting from one drive mode to the
other. When the shifting is completed,
the 4WD shift indicator will come on. If
the indicator does not come on immedi-
ately, make sure the area around the
vehicle is safe, and drive the vehicle
straight, accelerate or decelerate or
move the vehicle in reverse, then shift
the 4WD shift switch.
. If the 4WD warning light comes on, the
4WD shift indicator turns off.
