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, refer to “Engine
oil and oil filter recommendations” in the
“Technical and consumer information” sec-
tion of this manual. If any malfunction occurs in the Intelligent AWD
system while the engine is running, messages are
displayed in the meter.

INCREASING FUEL ECONOMYINTELLIGENT ALL-WHEEL DRIVE
(AWD) (if so equipped)
5-130Starting 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. 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 diameters 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
capability of the tires. Accelerating
quickly, sharp steering maneuvers or
sudden braking may cause loss of con-
trol, 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 ve-
hicle 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 damage or unexpected ve-
hicle movement which could result in
serious personal injury 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 dis-
played while driving there may be a
malfunction in the AWD system. Reduce
the vehicle speed immediately and have
your vehicle checked as soon as pos-
sible. It is recommended that you visit
an INFINITI retailer 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
engine. 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
displayed after the above operations,
have your vehicle checked as soon as
possible. It is recommended that you
visit an INFINITI retailer for this service.

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 system checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
The power steering system is designed to pro-
vide power assist while driving to operate the
steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. When the temperature of the power steer-
ing system goes down, the power assist level will
return to normal. Avoid repeating such steering 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 malfunc-
tion.
If the electric power steering warning light illumi-
nates while the engine is running, it may indicate
the power steering system is not functioning
properly and may need servicing. Have the power
steering system checked. It is recommended that
you visit an INFINITI retailer for this service.
When the electric power steering warning light
illuminates 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.
For additional information, refer to “Power steer-
ing warning light” in the “Instruments and con-
trols” section of this manual.
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
