ous damage to the engine almost immedi-
ately. Such damage is not covered by war-
ranty. Turn off the engine as soon as it is
safe to do so.
Power steering warning
light
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 recommended that you visit
an INFINITI retailer for this service.
Models with Direct Adaptive Steering®:
When the ignition switch is in the ON position,
the power steering warning light illuminates.
After starting the engine, the power steering
warning light stays on for a few seconds and
turns off. This indicates that Direct Adaptive
Steering is operational. Drive the vehicle after
the power steering warning light turns off.
If the power steering warning light illumi-
nates while driving, pull off the road to a safe
location and stop the vehicle. If the power steering warning light turns off, you can drive
again. If the power steering warning light
continues to illuminate, have the Direct
Adaptive Steering checked. It is recom-
mended that you visit an INFINITI retailer for
this service. For additional information, refer
to “Power Steering” in the “Starting and driv-
ing” section of this manual.
Models with electric power steering:
When the ignition switch is in the ON posi-
tion, the power steering warning light illumi-
nates. After starting the engine, the power
steering warning light turns off. This indicates
the electric power steering is operational.
If the power steering warning light illuminates
while the engine is running, it may indicate the
electric power steering is not functioning prop-
erly and may need servicing. It is recommended
that you have the electric power steering
checked by an INFINITI retailer.
When the power steering warning light illu-
minates with the engine running, the power
assist to the steering will cease operation but
you will still have control of the vehicle. At this
time, greater steering efforts are required to
operate the steering wheel, especially in
sharp turns and at low speeds. For additional
information, refer to “Power Steering” in the
“Starting and driving” section of this manual.

∙ The rain-sensing auto wipers are in-tended for use during rain. If the switch is
left in the AUTO position, the wipers may
operate unexpectedly when dirt, finger-
prints, oil film or insects are stuck on or
around the sensor. The wipers may also
operate when exhaust gas or moisture
affect the rain sensor.
∙ When the windshield glass is coated with water repellent, the speed of the rain-
sensing auto wipers may be higher even
though the amount of the rainfall is small.
∙ Be sure to turn off the rain-sensing auto wiper system when you use a car wash.
∙ The rain-sensing auto wipers may not operate if rain does not hit the rain sensor
even if it is raining.
∙ Using Genuine NISSAN wiper blades is recommended for proper operation of
the rain-sensing auto wiper system. For
additional information, refer to “Wind-
shield wiper blades” in the “Do-it-
yourself” section of this manual.
The rain-sensing auto wiper system can au-
tomatically turn on the wipers and adjust the
wiper speed depending on the rainfall and the
vehicle speed by using the rain sensor located
on the upper part of the windshield. To set the rain-sensing auto wiper system,
place the lever in the AUTO position1. The
wiper will sweep once while the ignition
switch is in the ON position.
The rain sensor sensitivity level can be ad-
justed by turning the knob toward the front
2(High) or toward the rear3(Low).
– High — High sensitive operation
– Low — Low sensitive operation
To turn the rain-sensing auto wiper system
off, rotate the lever to the OFF position, or
rotate the lever to the LO or HI position.
The rain-sensing feature may be disabled.

INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll
road device or automated payment device on
the key ring. Restart the engine using the
following procedures:1. Leave the ignition switch in the ON po- sition for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position and wait approximately
5 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices. ∙ Make sure the area around the vehicle is
clear.
∙ Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
∙ Check that all doors are closed.
∙ Position seat and adjust head restraints/headrests.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passengers to do likewise.
∙ Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.
2. Press the Park button to place the ve-
hicle in P (Park) or move the shift lever to
N (Neutral). P (Park) is recommended.
The starter is designed not to operate if
the shift lever is in any of the driving
positions.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the ignition
switch in any position.

starting, depress the accelerator pedal
a little (approximately 1/3 to the floor)
and while holding, crank the engine.
Release the accelerator pedal when
the engine starts.
∙ If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch to
the ON position to start cranking the
engine. After 5 or 6 seconds, stop
cranking by pushing the ignition switch

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.
