provide unnecessary warning.
. The system may not function in offset
conditions.
. The system may not function when the
distance to the vehicle ahead is extre-
mely close.
. The system is designed to automatically
check the sensor’s functionality. If the
sensor is covered with ice, a transparent
or translucent plastic bag, etc., the
system may not detect them. In these
instances the system may not be able to
warn the driver properly. Be sure to
check and clean the sensor regularly.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
. A sudden appearance of a vehicle in
front (for example, it abruptly cuts in)
may not be detected and the system may
not warn the driver soon enough.
. The system will be cancelled automati-
cally with a beep sound and the IBA OFF
indicator light will illuminate under the
following conditions:
—When the sensor window is dirty
—When the system malfunctions

If the IBA OFF indicator light*Ailluminates
with a beep sound, pull off the road to a
safe location, stop the vehicle and turn the
engine off. Check to see if the sensor
window is dirty. If the sensor window is
dirty, clean it with a soft cloth and restart
the engine. If the sensor window is not
dirty, restart the engine. If the IBA OFF
indicator light continues to illuminate even
if the IBA system is turned on with the IBA
OFF switch
*B, have the system checked
by an INFINITI retailer.
To turn on the IBA system, see “Intelligent
Cruise Control (ICC) system” later in this
section.

*2
button.
For the sensor maintenance, see “Intelli-
gent Cruise Control (ICC) system” earlier in
this section. The Intelligent Brake Assist (IBA) system
warns the driver by a warning light and
chime when there is a risk of a collision
with the vehicle ahead in the traveling lane
and the driver must take avoidance action
immediately. The system helps reduce the
rear-end collision speed by applying the
brakes when the system judges that the
collision cannot be prevented.
The IBA system will function when your
vehicle is driven at speeds of approxi-
mately 10 MPH (15 km/h) and above, and
when your vehicle is driven at speeds
approximately 10 MPH (15 km/h) faster
than the vehicle ahead.

Vehicle ahead detection indicatorThe IBA system uses a distance sensor
*A
located below the front bumper to measure
the distance to the vehicle ahead. When
the system judges that your vehicle is
getting close to the vehicle ahead in the
traveling lane, the vehicle ahead detection
indicator on the instrument panel blinks
and a warning chime sounds.
The IBA system will be turned on/off by
pushing the IBA OFF switch. The IBA OFF
indicator light will illuminate when the
system is turned off.
PRECAUTIONS ON IBA SYSTEM
WARNING
.
The IBA system is not a collision
avoidance system. 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, the
system may not provide a warning or
braking in certain conditions.
. The system will not detect the following
objects:
—Pedestrians, animals or obstacles in the roadway
—Motorcycles traveling offset in the
traveling lane
—Oncoming vehicles in the same lane
. The system will not detect another
vehicle under the following conditions:
—When the sensor gets dirty and it is
impossible to detect the distance
from the vehicle ahead.
—When driving into a strong light (for
example, sunlight).
. The sensor generally detects the signals
returned from the reflectors on a vehicle
ahead. Therefore, the system may not
function properly under the following
conditions:
—When the reflectors of the vehicle
ahead are positioned high or close to
each other (including a small vehicle
such as motorcycles).
—When the sensor gets dirty and it isimpossible to detect the distance
from the vehicle ahead.
—When the reflectors on the vehicleahead are missing, damaged or
covered.

5-96Starting and driving
—When the reflectors of the vehicleahead are covered with dirt, snow or
road spray.
—When visibility is low (such as rain,fog, snow, etc.).
—When snow or road spray from
traveling vehicles is splashed.
—When dense exhaust or other smoke (black smoke) from vehicles reduces
the visibility of the sensor.
—When excessively heavy baggage isloaded in the rear seat or the
luggage room of your vehicle.
—When abruptly accelerating or de-
celerating.
—On a steep downhill slope or onroads with sharp curves.
—When there is a highly reflective
object near the vehicle ahead (for
example, being very close to another
vehicle, signboard, etc.).
—When towing a trailer or othervehicle.
. Depending on certain road conditions
(curved or beginning of a curve), vehicle
conditions (steering position or vehicle position), or the preceding vehicle’
s
conditions (position in lane, etc.), the
system may not function properly.
. The system may not function in offset
conditions.
. The system may not function when the
distance to the vehicle ahead is extre-
mely close.
SSD0782
Reflectors on the road
WARNING
.The system may detect highly reflective
objects such as reflectors, signs, white
markers and other stationary objects on
the road or near the traveling lane.
In extreme conditions, detection of these
objects may cause the system to func-
tion.
. The system is designed to automatically
check the sensor’s functionality. If the
sensor is covered with ice, a transparent
or translucent plastic bag, etc., the

system may not detect them. In these
instances the system may not be able to
warn the driver properly. Be sure to
check and clean the sensor regularly.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
. A sudden appearance of a vehicle in
front (for example, it abruptly cuts in)
may not be detected and the system may
not warn the driver soon enough.
. The system will be cancelled automati-
cally with a beep sound and the IBA
warning light will illuminate under the
following conditions:
—When the sensor window is dirty
—When the system malfunctions
If the IBA OFF indicator light illuminates
with a beep sound, pull off the road to a
safe location, stop the vehicle and turn the
engine off. Check to see if the sensor
window is dirty. If the sensor window is
dirty, clean it with a soft cloth and restart
the engine. If the sensor window is not
dirty, restart the engine. If the IBA OFF
indicator light continues to illuminate even
if the IBA system is turned on, have the system checked by an INFINITI retailer.

Starting and driving5-97

5-100Starting 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
recommendation” in the“9. Technical
and consumer information” section.)
WARNING
.Do not attempt 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 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 dynamometer 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
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 vehicleand 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 by an INFINITI retai-
ler as soon as possible.
. The transfer case may be damaged if you
continue driving with the 4WD warning
light blinking.
See “On-pavement and off-road driving
precautions” earlier in this section for
other precautions for offroad driving.
INCREASING FUEL ECONOMY INFINITI ALL-MODE 4WD®(if so equipped)

The 4WD shift switch is used to select the
4WD mode depending on the driving
conditions. There are 3 types of drive
modes available, AUTO, 4HI and 4LO.
The 4WD shift switch electronically con-
trols 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
stationary 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 unexpect-
edly move even if the automatic trans-
mission 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 transmission 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 alternately, the vehicle may
move unexpectedly.
CAUTION
.
Never shift the 4WD shift switch be-
tween 4L and 4H while driving.
. The 4HI position provides greater trac-
tion. Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could da-
mage 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 reversing.
. Do not shift the 4WD shift switch
(between AUTO and 4H) while driving
on steep downhill grades. Use the engine brake and low automatic trans-
mission gears for engine braking.
. 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 between 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
