∙ Do not modify the vehicle’s steering. Ifsteering 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 il-
luminate 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, refer to “Vehicle Dynamic
Control (VDC) system” in this section.
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, refer to “INFINITI
Drive Mode Selector” in this section.
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, refer to
“Power steering warning light” in the “Instru-
ments and Controls” section of the manual.
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
steering wheel will return to the normal posi-
tion after the protection mechanism is deac-
tivated.
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
∙ 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-

To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
∙ If done incorrectly, jump starting can leadto a battery explosion, resulting in severe
injury or death. It could also damage your
vehicle.
∙ Explosive hydrogen gas is always present in the vicinity of the battery. Keep all
sparks and flames away from the
battery.
∙ Do not allow battery fluid to come into contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a corro-
sive sulfuric acid solution which can cause
severe burns. If the fluid should come into
contact with anything, immediately flush
the contacted area with water.
∙ Keep battery out of the reach of children.
∙ The booster battery must be rated at 12 volts. Use of an improperly rated bat-
tery can damage your vehicle. ∙ Whenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
∙ Do not attempt to jump start a frozen battery. It could explode and cause seri-
ous injury.
∙ The automatic engine cooling fan (if so equipped) may come on at any time with-
out warning, even if the ignition switch is
in the OFF position and the engine is not
running. To avoid injury, keep hands and
other objects away from it.
JUMP STARTING
In case of emergency6-5

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
∙ Park the vehicle on a level surface, applythe parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Move the shift lever to P (Park).
∙ Be sure the ignition switch is in the OFF or LOCK position when performing any
parts replacement or repairs.
∙ If you must work with the engine running, keep your hands, clothing, hair and tools
away from moving fans, belts and any
other moving parts.
∙ It is advisable to secure or remove any loose clothing and remove any jewelry,
such as rings, watches, etc. before work-
ing on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position and
the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
∙ If you must run the engine in an enclosed space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
∙ Never get under the vehicle while it is supported only by a jack. If it is necessary
to work under the vehicle, support it with
safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ Because the fuel lines on gasoline engine models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
∙ Do not work under the hood while theengine is hot. Turn the engine off and
wait until it cools down. ∙ Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
∙ Never leave the engine or Continuously Variable Transmission (CVT) related
component harnesses disconnected
while the ignition switch is in the ON
position.
∙ Never connect or disconnect the battery or any transistorized component while
the ignition switch is in the ON position.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine INFINITI service manual is also
available. For additional information, refer to
“Owner’s Manual/Service Manual order in-
formation” in the “Technical and consumer
information” section of this manual.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

WARNING
∙ Do not expose the battery to flames, anelectrical spark or a cigarette. Hydrogen
gas generated by the battery is explo-
sive. Explosive gases can cause blindness
or injury. Do not allow battery fluid to
contact your skin, eyes, fabrics or painted
surfaces. Sulfuric acid can cause blind-
ness or injury. After touching a battery or
battery cap, do not touch or rub your
eyes. Thoroughly wash your hands. If the
acid contacts your eyes, skin or clothing,
immediately flush with water for at least
15 minutes and seek medical attention.
∙ Do not operate the vehicle if the fluid in the battery is low. Low battery fluid can
cause a higher load on the battery which
can generate heat, reduce battery life,
and in some cases lead to an explosion.
∙ When working on or near a battery, al- ways wear suitable eye protection and
remove all jewelry.
∙ Battery posts, terminals and related ac- cessories contain lead and lead com-
pounds. Wash hands after handling.
∙ Keep battery out of the reach of children.
∙ Do not tip the battery. Keep the vent caps tight and the battery level. NOTE:
Do not try to open the top of the battery.
This battery is not equipped with removable
vent caps.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, refer to “Jump
starting” in the “In case of emergency” section
of this manual. If the engine does not start by
jump starting, the battery may have to be
replaced. It is recommended that you visit an
INFINITI retailer for this service.
