roads, change (not just inspect) oil every
20,000 miles (32,000 km) or 24 months.(2) If the oil replacement indicator is dis-
played, change the engine oil and filter within
two weeks or less than 500 miles (800 km).
(3) If operating mainly in dusty conditions,
more frequent maintenance may be required.
* Maintenance items and intervals with“*”
are recommended by NISSAN for reliable ve-
hicle operation. The owner need not perform
such maintenance in order to maintain the
emission warranty or manufacturer recall li-
ability. Other maintenance items and inter-
vals are required.

Power steering warning
light
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 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 sys-
tem checked. It is recommended that you
visit an INFINITI retailer for this service.
Models with Direct Adaptive Steering®:
When the ignition switch is in the ON posi-
tion, the power steering warning light illumi-
nates. After starting the engine, the power
steering warning light stays on for a few
seconds and turns off. This indicates that
Direct Adaptive Steering is operational. Drive
the vehicle after the power steering warning
light turns off.
If the power steering warning light illumi-
nates while driving, pull off the road to a safe
location and stop the vehicle. If the power
steering warning light turns off, you can drive again. If the power steering warning light
continues to illuminate, have the Direct
Adaptive Steering checked. It is recom-
mended that you visit an INFINITI retailer for
this service. For additional information, see
“Power Steering”. (P. 5-149).
Models with electric power steering:
When the ignition switch is in the ON posi-
tion, the power steering warning light illumi-
nates. After starting the engine, the power
steering warning light turns off. This indicates
the electric power steering is operational.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the electric power steering is not func-
tioning properly and may need servicing. It is
recommended that you have the electric
power steering checked by an INFINITI
retailer.
When the power steering warning light illu-
minates with the engine running, the power
assist to the steering will cease operation but
you will still have control of the vehicle. At this
time, greater steering efforts are required to
operate the steering wheel, especially in
sharp turns and at low speeds. For additional
information, see “Power Steering” (P. 5-149).
Rear Automatic Braking
(RAB) warning light
This light comes on when the ignition switch
is placed in the ON position. It turns off after
the engine is started.
This light illuminates when the RAB system is
turned off in the vehicle information display.
If the light illuminates when the RAB system
is on, it may indicate that the system is un-
available. For additional information, see
“Rear Automatic Braking (RAB)” (P. 5-118).
Slip indicator light
This indicator light will blink when the VDC
system is operating, thus alerting the driver to
the fact that the road surface is slippery and
the vehicle is nearing its traction limits.
You may feel or hear the system working; this
is normal.
The light will blink for a few seconds after the
VDC system stops limiting wheel spin.

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 when the AWD tem-
perature or tire size incorrect messages
are displayed.
• 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.

• HEADED UPHILL OR DOWNHILL,NO CURB
OC:
Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.

TYPE
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 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 sys-
tem checked. It is recommended that you
visit an INFINITI retailer 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 return to normal. Avoid repeating such steer-
ing wheel operations that could cause the
power steering system to overheat.
You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the power steering system is not func-
tioning properly and may need servicing.
Have the power steering system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When the power steering warning light illu-
minates with the engine running, there will be
no power assist for the steering, but you will
still have control of the vehicle. At this time,
greater steering effort is required to operate
the steering wheel, especially in sharp turns
and at low speeds.

ing warning light” (P. 2-16).
