the accelerator pedal up or apply
partial braking. When acceleration is
necessary, continue to depress the
accelerator pedal to override the
system.
. The system is designed to automati-
cally check the sensor’s functionality,
within certain limitations. The system
may not detect some forms of ob-
struction of the sensor area such as
ice, snow, 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
the sensor area regularly.
. The FEB system may react to:
— objects on the roadside (traffic sign, guardrail, vehicle, etc.)

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 run-
ning, the power assist for the steer-
ing will cease operation. You will still
have control of the vehicle but the
steering will be harder to operate.
The electric power steering is designed to
provide power assist while driving to oper-
ate the steering wheel with light force.
When the steering wheel is operated re-
peatedly 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 overheating of the electric power
steering and protect it from getting da-
maged. While the power assist is reduced,
steering wheel operation will become heavy.
When the temperature of the electric power
steering goes down, the power assist level
will return to normal. Avoid repeating such steering wheel operations that could cause
the electric power steering 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
indicate the electric power steering is not
functioning properly and may need servicing.
It is recommended you have the electric
power steering checked by an INFINITI
retailer. (See “Power steering warning light”
(P.2-16).)
When the power steering warning light
illuminates with the engine running, the
power assist for the steering will cease
operation. You will still have control of the
vehicle. However, greater steering effort is
needed, especially in sharp turns and at low
speeds.
DIRECT ADAPTIVE STEERING
TYPE
WARNING
.
When the power steering warning
light illuminates with the engine run-
ning, the power assist for the steer-
ing will cease operation. You will still
POWER STEERING

have control of the vehicle, but the
steering will be harder to operate.
. If wheels or tires other than the
INFINITI recommended ones are
used, Direct Adaptive Steering may
not operate properly and the power
steering warning light may illumi-
nate.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not INFINITI recommended for your
vehicle or are extremely deteriorated,
Direct Adaptive Steering may not
operate properly and the power
steering warning light may illumi-
nate.
. Do not modify the vehicle’s steering.
If steering parts are not INFINITI
recommended for your vehicle or are
extremely deteriorated, Direct Adap-
tive Steering may not operate prop-
erly and the power steering warning
light may illuminate.
. If the VDC warning light illuminates,
the power steering warning light may
also illuminate at the same time. Stop
the vehicle in a safe location, turn the
engine off and restart the engine. If
the power steering warning light continues to illuminate, have the
system checked. It is recommended
you visit an INFINITI retailer for this
service. For VDC system, see “Vehicle
Dynamic Control (VDC) system”
(P.5-131).
CAUTION
.
Do not place the ignition switch is in
the ON position while the steering
wheel or a tire is removed.
. Do not turn the steering wheel as
much as possible while the ignition
switch is in any position other than
the ON position.
. Installing an accessory on the steer-
ing wheel, or changing the steering
wheel, may reduce the steering per-
formance.
Direct Adaptive Steering is designed to
control the steering force and steering angle
according to the vehicle speed and amount
of turning of the steering wheel.
The steering characteristic can be selected
using the INFINITI Drive Mode Selector. See
“INFINITI Drive Mode Selector” (P.5-21).
If the VDC system is turned off, the setting of steering becomes standard mode.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate that Direct Adaptive Steering is not
functioning properly and may need servicing.
It is recommended you have the system
checked by an INFINITI retailer. (See “Power
steering warning light” (P.2-16).)
When the power steering warning light
illuminates with the engine running, the
power assist for the steering will cease
operation. You will still have control of the
vehicle. However, greater steering effort will
be needed, especially in sharp turns and at
low speeds.
If Direct Adaptive Steering is malfunction-
ing, the steering wheel may turn slightly even
when driving on a straight road.
Under the following conditions, the steering
wheel may turn slightly even when driving on
a straight road. This is due to a protection
mechanism for Direct Adaptive Steering. The
steering wheel will return to the normal
position after the protection mechanism is
deactivated.
Condition A
.
When the engine is stalled or likely to be
stalled
. When the steering wheel is held in the full
lock position or when the front tire
touches an obstruction.
