The vehicle should be driven with the
Vehicle Dynamic Control (VDC) system on
for most driving conditions.
If the vehicle is stuck in mud or snow, the
VDC system reduces the engine output to
reduce wheel spin. The engine speed will
be reduced even if the accelerator is
depressed to the floor. If maximum engine
power is needed to free a stuck vehicle,
turn the VDC system off.
To turn off the VDC system, push the VDC
OFF switch. The
indicator light will
illuminate.
Push the VDC OFF switch again or restart
the engine to turn on the system. (See “Vehicle Dynamic Control (VDC) system”

HYDRAULIC POWER STEERING 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.
The power assisted steering uses a hy-
draulic pump, driven by the engine, to
assist steering.
If the engine stops or the drive belt breaks,
you will still have control of the vehicle.
However, much 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 running, the
power assist for the steering will cease
operation. You will still have control of the
vehicle, but the steering will be harder to
operate.
CAUTION
.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 illuminate.
. Do not modify the vehicle’s suspension.
If suspension parts such as shock
absorbers, struts, springs, stabilizer
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 illuminate.
. Do not modify the vehicle’s steering. If
steering parts are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, Direct Adaptive Steering
may not operate properly 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
by an INFNITI retailer. For VDC system,
see
“Vehicle Dynamic Control (VDC)
system” (P.5-108).
. 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 steering
wheel, or changing the steering wheel,
may reduce the steering performance.
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
with the INFINITI Drive Mode Selector. See
“INFINITI Drive Mode Selector” (P.5-21).
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 and the steering wheel may be
slightly turned even when driving on a
POWER STEERING

straight road. This is to prevent overheat-
ing of Direct Adaptive Steering and protect
it from getting damaged. When the tem-
perature of Direct Adaptive Steering cools
down, the power assist level will return to
normal. Avoid repeating steering wheel
operations that could cause Direct Adap-
tive Steering to overheat.
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. 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 steer-
ing wheel may turn slightly even when
driving on a straight road. This is due to a
protection mechanism for Direct Adaptive Steering.
.
When the battery is discharged
. When the engine is stalled
. After the vehicle is tested on the four-
wheel dynamometer
. When the steering wheel is held in the
full lock position or when the front tire
touches an obstruction.
The steering wheel will return to the
normal position after the protection me-
chanism deactivates. To return to the
normal position, turn the engine off, restart
the engine, and then drive the vehicle for a
period of time.
When the vehicle is tested on the 2-wheel
dynamometer, the power steering warning
light may illuminate. To turn off the power
steering warning light, stop the vehicle in a
safe location, turn the engine off, restart
the engine, and then drive the vehicle for a
period of time.
The following conditions do not indicate a
malfunction of Direct Adaptive Steering.
. You may notice wider steering play
when the ignition switch is in the OFF
or ACC position compared to when it is
in the ON position. .
After the engine is started, the steering
wheel may turn slightly even when
driving on a straight road. To return to
the normal position, drive the vehicle
on a straight road for a period of time.
. After the engine is started, the steering
wheel may move if the steering wheel
was turned to the fully locked position
while the ignition switch was in the OFF
position.
You may hear a noise under the following
conditions. However, this is not a malfunc-
tion.
. When the engine is started or stopped.
. When the steering wheel is turned in
the full lock position.
