CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.

tion, the master warning light illuminates if
any of the following (if so equipped) are dis-
played on the vehicle information display:
• I-Key system warnings
• Low washer fluid warning
• Door/ liftgate open warning (when vehicle is stopped)
• Loose fuel cap warning

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. 5-136).
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.
2-16Instruments and controls

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. 5-136).
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. 5-104).
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.
The
indicator light also comes on when
you place the ignition switch in the ON posi-
tion. The light will turn off after a period of
time if the system is operational. If the light
does not come on have the system checked. It
is recommended that you visit an INFINITI
retailer for this service.
Vehicle Dynamic Control
(VDC) OFF indicator light
This indicator light comes on when the VDC is
turned off in the lower display. This indicates
the VDC has been turned off.
Turn the VDC on again by reactivating it in
the lower display, or restarting the engine.
The system will be reactivated. For additional
information, see “Vehicle Dynamic Control
(VDC) system” (P. 5-141).
The VDC light also comes on when the igni-
tion switch is placed in the ON position. The
light will turn off after a period of time if the
system is operational. If the light stays on or
comes on along with the
indicator light
while you are driving, have the VDC system
checked. It is recommended that you visit an
INFINITI retailer for this service.
WARNING
VDC should remain on unless freeing a ve-
hicle from mud or snow.
While the VDC system is operating, you
might feel a slight vibration or hear the sys-
tem working when starting the vehicle or ac-
celerating, but this is normal.
WARNING/INDICATOR LIGHTS
(other)
For additional information, see “Vehicle in-
formation display” (P. 2-19).
Automatic brake hold
indicator light (white/green)
This light illuminates to show the status of
the automatic brake hold system.
When the automatic brake hold system is on
standby, the indicator will illuminate white.
When the automatic brake hold system is
operating, the indicator will illuminate green.
For additional information, see “Automatic
brake hold” (P. 5-26).

circumstance, tire pressure may not cor-
rectly be displayed.

The tire size message may be displayed if
there is a large difference between the diam-
eters of front and rear wheels. 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 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 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.
