AWD High Temp. Stop vehicle
This warning may appear while trying to free
a stuck vehicle due to increased oil tempera-
ture. The driving mode may change to
2-Wheel Drive (2WD). If this warning is dis-
played, stop the vehicle with the engine idling,
as soon as it is safe to do so. Then if the
warning turns off, you can continue driving.
AWD Tire Size Incorrect: See
Owner’s Manual
This warning may appear if there is a large
difference between the diameters of the
front and rear wheels. Pull off the road in a
safe area, with the engine idling. Check that
all the tire sizes are the same, that the tire
pressure is correct and that the tires are not
excessively worn.
CVT (AT) Malfunction Service now
This warning appears when there is a prob-
lem with the CVT system. If this warning
comes on, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
CVT (AT) hot Power reduced
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, climbing
steep grades in high temperatures with heavy
loads, such as when towing a trailer), engine
power and, under some conditions, vehicle
speed will be decreased automatically to re-
duce the chance of transmission damage.
Vehicle speed can be controlled with the ac-
celerator pedal, but the engine and vehicle
speed may be reduced.
WARNING
When the high fluid temperature protec-
tion mode operation occurs, vehicle speed
may be gradually reduced. The reduced
speed may be lower than other traffic,
which could increase the chance of a colli-
sion. Be especially careful when driving. If
necessary, pull to the side of the road at a
safe place and allow the transmission to
return to normal operation; or have it re-
paired if necessary.
Engine hot Power reduced
This engine has a high fluid temperature pro-
tection mode. If the fluid temperature be-
comes too high (for example, climbing steep
grades in high temperatures with heavy
loads, such as when towing a trailer), engine
power and, under some conditions, vehicle
speed will be decreased automatically to re-
duce the chance of engine damage. Vehicle
speed can be controlled with the accelerator
pedal, but the engine and vehicle speed may
be reduced.
WARNING
When the high fluid temperature protec-
tion mode operation occurs, vehicle speed
may be gradually reduced. The reduced
speed may be lower than other traffic,
which could increase the chance of a colli-
sion. Be especially careful when driving. If
necessary, pull to the side of the road at a
safe place and allow the engine to return to
normal operation; or have it repaired if
necessary.
Instruments and controls2-29

NOTE:
If the driver lightly touches (instead of firmly
grips) the steering wheel, the steering
torque sensor may not detect the driver’s
hand(s) on the steering wheel and a sequence
of warnings may occur. When the driver
holds and operates the steering wheel again,
the warnings turn off.
Steering Assist limitations
WARNING
• In the following situations, the camera
may not detect lane markers correctly or
may detect lane markers incorrectly and
the Steering Assist may not operate
properly:
– When driving on roads where there
are multiple parallel lane markers,
lane markers that are faded or not
painted clearly, nonstandard lane
markers, or lane markers covered
with water, dirt, snow, etc.
– When driving on roads with discon-
tinued lane markers
– When driving on roads with a widen-
ing or narrowing lane width –
When driving on roads where there
are multiple lanes or unclear lane
markers due to road construction
– When driving on roads where there
are sharply contrasting objects, such
as shadows, snow, water, wheel ruts,
seams, or lines remaining after road
repairs (the Steering Assist could de-
tect these items as lane markers)
– When driving on roads where the
traveling lane merges or separates
• Do not use the Steering Assist under the
following conditions because the system
may not properly detect lane markers.
Doing so could cause a loss of vehicle
control and result in an accident.
– During bad weather (rain, fog, snow,
dust, etc.)
– When rain, snow, sand, etc., is thrown
up by the wheels of other vehicles
– When dirt, oil, ice, snow, water, or an-
other object adheres to the camera
unit
– When the lens of the camera unit is
foggy
– When strong light (for example, sun-
light or high beams from oncoming
vehicles) shines on the camera –
When the headlights are not bright
due to dirt on the lens or the head-
lights are off in tunnels or darkness
– When a sudden change in brightness
occurs (for example, when the vehicle
enters or exits a tunnel or is under a
bridge)
–
When driving on roads where the trav- eling lane merges or separates or
where there are temporary lane mark-
ers because of road construction
– When there is a lane closure due to
road repairs
– When driving on a bumpy road sur-
face, such as an uneven dirt road
– When driving on sharp curves or
winding roads
– When driving on repeated uphill and
downhill roads
• Do not use the Steering Assist under the
following conditions because the system
will not operate properly:
– When driving with a tire that is not
within normal tire conditions (for ex-
ample, tire wear, abnormal tire pres-
sure, installation of a spare tire, tire
chains, nonstandard wheels)
–
When the vehicle is equipped with non- original brake or suspension parts
5-98Starting and driving

The AWD high temperature message may be
displayed while trying to free a stuck vehicle
due to increased oil temperature. The driving
mode may change to 2-Wheel Drive (2WD).
If this message is displayed, stop the vehicle
with the engine idling, as soon as it is safe to
do so. Then if the message turns off, you can
continue driving.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.
