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 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.
The power steering system is designed to
provide power assist while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assist for the
steering wheel will be reduced. This is to pre-
vent overheating of the power steering sys-
tem and protect it from getting damaged. While the power assist is reduced, steering
wheel operation will become heavy. When
the temperature of the power steering sys-
tem goes down, the power assist level will
return to normal. Avoid repeating such steer-
ing 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 malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the power steering system is not func-
tioning properly and may need servicing.
Have the power steering system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When the power steering warning light illu-
minates 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, see “Power steer-
ing warning light” (P. 2-16).

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.
• 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
parts such as shock absorbers, struts,
springs, stabilizer bars, bushings and
wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, 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 Vehicle Dynamic Control (VDC)
OFF indicator light illuminates, the
power steering warning light may also
illuminate at the same time. Stop the ve-
hicle in a safe location, turn the engine
off and restart the engine. If the power
steering warning light continues to illu-
minate, have the system checked. It is
recommended that you visit an INFINITI
retailer for this service. For additional in-
formation, see “Vehicle Dynamic Control
(VDC) system” (P. 5-142).
CAUTION
• Do not place the ignition switch 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
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 con-
trol the steering force and steering angle ac-
cording to the vehicle speed and amount of
turning of the steering wheel. The steering characteristic can be selected
using the INFINITI Drive Mode Selector. For
additional information, see “INFINITI Drive
Mode Selector” (P. 5-29).
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 indi-
cate that Direct Adaptive Steering is not
functioning properly and may need servicing.
Have the system checked. It is recommended
that you visit an INFINITI retailer for this
service. For additional information, see
“Power steering warning light” (P. 2-16)
When the power steering warning light illu-
minates with the engine running, the power
assist for the steering will cease operation.
You will still have control of the vehicle. How-
ever, greater steering effort will be needed,
especially in sharp turns and at low speeds.
If Direct Adaptive Steering is malfunctioning,
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
5-138Starting and driving

steering wheel will return to the normal posi-
tion after the protection mechanism is
deactivated.
Condition A:
• When the engine is stalled or likely to bestalled
• When the steering wheel is held in the full lock position or when the front tire touches
an obstruction
• When the battery is discharged
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and stop operating the steering wheel. Then
drive the vehicle for a short period of time.
Condition B:
• When the steering wheel is operated re- peatedly or continuously while parking or
driving at a very low speed. In this case, the
power assist for the steering wheel will be
reduced.
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and wait for a period of time, without oper-
ating the steering wheel, until the tempera-
ture of Direct Adaptive Steering cools down.
Avoid repeated steering wheel operations
that could cause Direct Adaptive Steering to
overheat. 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 AUTO
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 a
straight road. To return to the normal posi-
tion, 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.
• After the vehicle is tested on the 4–wheel dynamometer, the steering wheel may turn
slightly even when driving on a straight
road. To return the steering wheel to the
normal position, drive the vehicle on a
straight road for a period of time. 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.
Starting and driving5-139

The VDC system uses various sensors to
monitor driver inputs and vehicle motion. Un-
der certain driving conditions, the VDC sys-
tem helps to perform the following functions:
• Controls brake pressure to reduce wheelslip on one slipping drive wheel so power is
transferred to a non-slipping drive wheel
on the same axle.
• Controls brake pressure and engine output to reduce drive wheel slip based on vehicle
speed (traction control function).
• Controls brake pressure at individual wheels and engine output to help the driver
maintain control of the vehicle in the fol-
lowing conditions:
Understeer (vehicle tends to not follow the
steered path despite increased steering input)
Oversteer (vehicle tends to spin due to certain
road or driving conditions)
The VDC system can help the driver to main-
tain control of the vehicle, but it cannot pre-
vent loss of vehicle control in all driving
situations. When the VDC system operates, theindicator light in the instrument panel flashes
to note the following:
• The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
• You may feel a pulsation in the brake pedal and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
• Adjust your speed and driving to the road conditions.
For additional information, see “Slip indicator
light” (P. 2-17) and ”Vehicle Dynamic Control
(VDC) OFF indicator light” (P. 2-17).
If a malfunction occurs in the system, the
andindicator lights come on in the
instrument panel. The VDC system automati-
cally turns off when these indicator lights are
on.
The lower display is used to turn off the VDC
system. When the VDC system is turned off,
the
indicator light, the RAB system
warning light, and the FEB with Pedestrian
Detection system warning light illuminate to
indicate the VDC, FEB with Pedestrian De-
tection, and RAB systems are off. When the lower display is used to turn off the
system, the VDC system still operates to pre-
vent one drive wheel from slipping by trans-
ferring power to a non-slipping drive wheel.
The
indicator light flashes if this occurs.
All other VDC functions are off and the
indicator light will not flash.
The VDC system is automatically reset to on
when the ignition switch is placed in the OFF
position then back to the ON position.
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in re-
verse at a slow speed. When the self-test oc-
curs, you may hear a clunk noise and/or feel a
pulsation in the brake pedal. This is normal and
is not an indication of a malfunction.
WARNING
• The VDC system is designed to help the
driver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving tech-
niques. Reduce vehicle speed and be es-
pecially careful when driving and corner-
ing on slippery surfaces and always drive
carefully.

To shut off the engine in an emergency situ-
ation while driving, perform the following
procedure:
– Rapidly push the push-button ignitionswitch three consecutive times in less than
1.5 seconds, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires. When the low tire pres-
sure warning light is lit, and the “Tire Pressure
Low - Add Air” warning appears in the vehicle
information display, one or more of your tires
is significantly under-inflated. The system
also displays pressure of all tires (except the
spare tire) on the vehicle information display
screen by sending a signal from a sensor that
is installed in each wheel. If the vehicle is
being driven with low tire pressure, the TPMS
will activate and warn you of it by the low tire
pressure warning light. This system will acti-
vate only when the vehicle is driven at speeds
above 16 mph (25 km/h). For additional in-
formation, see “Warning lights, indicator
lights and audible reminders” (P. 2-9) and
“Tire Pressure Monitoring System (TPMS)”
(P. 5-5).
WARNING
• Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use. •
If the low tire pressure warning light illu-
minates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage could
occur and may lead to an accident and
could result in serious personal injury.
Check the tire pressure for all four tires.
Adjust the tire pressure to the recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
OFF. If the light still illuminates while
driving after adjusting the tire pressure,
a tire may be flat or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a replacement tire as soon
as possible. If no tires are flat and all tires
are properly inflated, have the vehicle
checked. It is recommended that you
visit an INFINITI retailer for this service.

Two-Wheel Drive models with
Continuously Variable Transmission
(CVT)
INFINITI recommends that your vehicle be
towed with the driving (front) wheels off the
ground or place the vehicle on a flatbed truck
as illustrated.
NOTE:
If the electronic parking brake is released,
the rear wheels can be grounded while tow-
ing. If the electronic parking brake is not
released, towing dollies should be used.
For additional information, see “Electronic
parking brake” (P. 5-24).
CAUTION
• Never tow Continuously Variable Trans-
mission (CVT) models with the front
wheels on the ground or four wheels on
the ground (forward or backward), as
this may cause serious and expensive
damage to the transmission. If it is nec-
essary to tow the vehicle with the rear
wheels raised always use towing dollies
under the front wheels.
•
When towing Continuously Variable
Transmission (CVT) models with the rear
wheels on the ground or on towing dollies:
– Place the ignition switch in the OFF
position, and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
secure the steering wheel by placing
the ignition switch in the LOCK posi-
tion. This may damage the steering
lock mechanism (for models with a
steering lock mechanism).
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
