Steering Assist maintenance
The camera sensor is located above the in-
side mirror.
To keep the proper operation of the system
and prevent a system malfunction, be sure to
observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar-ent material) or install an accessory near
the camera unit. • Do not place reflective materials, such as
white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the camera
lens or remove the screw located on the
camera unit.
If the camera unit is damaged due to an
accident, it is recommended that you visit an

–When your vehicle or the vehicle or
pedestrian ahead moves quickly or
significantly such that the system
cannot detect and react in time (for
example, pedestrian moving quickly
toward the vehicle at close range, ve-
hicle cutting in, changing lanes, mak-
ing a turn, steering abruptly, sudden
acceleration or deceleration).
– When the vehicle or pedestrian is off-
set from the vehicle’s forward path.
– If the speed difference between the
two vehicles is small.
– The pedestrian’s profile is partially
obscured or unidentifiable; for ex-
ample, due to transporting luggage,
pushing a stroller, wearing bulky or
very loose-fitting clothing or acces-
sories, or being in a unique posture
(such as raising hands).
– There is poor contrast of a person to
the background, such as having
clothing color or pattern which is
similar to the background.
– For approximately 15 seconds after
starting the engine.
– If the vehicle ahead has a unique or
unusual shape, extremely low or high
clearance heights, or unusual cargo
loading or is narrow (for example, a
motorcycle). –
When the vehicle or pedestrian is lo-
cated near a traffic sign, a reflective
area (for example, water on road), or
is in a shadow.
– When multiple pedestrians are
grouped together.
– When the view of the pedestrian is
obscured by a vehicle or other object.
– While towing a trailer or other
vehicle.
• The system performance may degraded
in the following conditions:
– The vehicle is driven on a slippery
road.
– The vehicle is driven on a slope.
– Excessively heavy baggage is loaded
in the rear seat or the cargo area of
your vehicle.
• The system is designed to automatically
check the sensor’s (radar and camera)
functionality, within certain limitations.
The system may not detect some forms
of obstruction of the sensor area such as
ice, snow or stickers, for example. In
these cases, the system may not be able
to warn the driver properly. Be sure that
you check, clean and clear sensor areas
regularly. •
In some road and traffic conditions, the
FEB with Pedestrian Detection system
may unexpectedly apply partial braking.
When acceleration is necessary, depress
the accelerator pedal to override the
system.
• The FEB with Pedestrian Detection sys-
tem may operate when a pattern, object,
shadow or lights are detected that are
similar to the outline of vehicles or pe-
destrians, or if they are the same size and
position as a vehicle or motorcycle’s tail
lights.
• The system may keep operating when
the vehicle ahead is turning right or left.
• The system may operate when your ve-
hicle is approaching and passing a vehicle
ahead.
• Depending on the road shape (curved
road, entrance and exit of the curve,
winding road, lane regulation, under
construction, etc.), the system may op-
erate temporarily for the oncoming ve-
hicle in front of your vehicle.

• Keep your engine tuned up.
• Follow the recommended scheduledmaintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire wear
and lowers fuel economy.
• Keep all the wheels in correct alignment. Improper alignment increases tire wear and
lowers fuel economy.
• Use the recommended viscosity engine oil. For additional information, see “Engine oil
and oil filter recommendations” (P. 10-6).
If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.
If the AWD error warning message is dis-
played, there may be a malfunction in the
Intelligent AWD system. Reduce vehicle
speed and have your vehicle checked as soon
as possible. It is recommended that you visit
an INFINITI retailer for this service. The AWD high temperature message may be
displayed when the oil temperature of the
powertrain parts increases due to the differ-
ence in rotation between the front and rear
wheels is large (wheel slip), such as when
driving on rough roads, driving through sand
or mud, or feeling a stuck vehicle. If this
warning is displayed, stop the vehicle with the
engine idling, as soon as it is safe to do so. In
these cases, the AWD changes to 2WD to
protect the powertrain parts. Then if the
warning turns off, you can continue AWD
driving.

The tire size message may be displayed if
there is a large difference between the diam-
eters of front and rear wheels and tires. Pull
off the road in a safe area, with the engine
idling. Check that all tire sizes, brand, con-
struction and tread pattern are the same, that
the tire pressures are correct and that the
tires are not excessively worn. If you have any
problems, change tires or adjust tire pres-
sures correctly. Do not select the SNOW
mode with the INFINITI Drive Mode Selector
and do not drive fast.If any warning messages continue to be dis-
played, have your vehicle checked as soon as
possible. It is recommended that you visit an
INFINITI retailer for this service.
WARNING
• Do not drive beyond the performance ca-
pability of the tires. Accelerating quickly,
sharp steering maneuvers or sudden
braking may cause loss of control, even
with Intelligent AWD engaged.
• For AWD 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 vehicle movement which
could result in serious personal injury or
vehicle damage. •
Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure that you inform the
test facility personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious personal in-
jury or vehicle damage.
CAUTION
• Do not operate the engine on a free roller
when any of the wheels are raised.
• If you use the free roller, rotate four
wheels with the same speed without
raising any wheels.
• If an AWD warning message is displayed
while driving there may be a malfunction
in the AWD system. Reduce the vehicle
speed immediately and have your vehicle
checked as soon as possible. It is recom-
mended that you visit an INFINITI re-
tailer for this service.

•The powertrain may be damaged if you
continue driving with AWD error
warning on.
• If the AWD high temperature message is
displayed while you are driving, pull off
the road in a safe area, and idle the en-
gine. The driving mode will change to
2WD to prevent the AWD system from
malfunctioning. If the warning message
turns off, you can drive again.
• If the tire size incorrect message is dis-
played while you are driving, pull off the
road in a safe area with the engine idling.
Check that all tire sizes are the same,
that the tire pressure is correct and that
the tires are not excessively worn.
• If a warning message continues to be dis-
played after the above operations, have
your vehicle checked as soon as possible.
It is recommended that you visit an
INFINITI retailer for this service.
When the vehicle is in the P (Park) position,
the operation noise may be heard from the
lower part of the vehicle. This is not a
malfunction.
WARNING
• Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
• Safe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park). Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and re-
sult in an accident. Make sure the shift
lever has been pushed as far forward as it
can go and cannot be moved without de-
pressing the foot brake pedal. •
Never leave the engine running while the
vehicle is unattended.
• Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or make the
vehicle move. Unattended children could
become involved in serious accidents.

•To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm day
can quickly become high enough to cause
a significant risk of injury or death to
people and pets.
1. Firmly apply the parking brake.
2. Push the park button to engage the P (Park) position.
3. To help prevent the vehicle from rolling into traffic when parked on an incline, it is
a good practice to turn the wheels as
illustrated.

4. Place the ignition switch in the LOCK position.WARNING
• If the engine is not running or is turned
off while driving, the power assist for the
steering will not work. Steering will be
harder to operate.
• When the electric power steering
warning light illuminates with the engine
running, there will be no power assist for
the steering. You will still have control of
the vehicle, but the steering will be
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
The power steering system is designed to
provide power assist while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assist for the
steering wheel will be reduced. This is to pre-
vent overheating of the power steering sys-
tem and protect it from getting damaged.
While the power assist is reduced, steering
wheel operation will become heavy. When
the temperature of the power steering sys-
tem goes down, the power assist level will
