VARIABLE COMPRESSION
TURBO
Your engine is equipped with a variable com-
pression ratio system called “Variable Com-
pression Turbo”. This system can vary the
engine compression ratio continuously.
According to driving conditions, the system
applies optimum compression ratio auto-
matically to achieve both high output and
high fuel economy efficiency.This is not a physical gauge. It is a display
option in the vehicle information display that
can be selected. For additional information,
refer to “Vehicle information display” in this
section.
1Compression ratio status display
Displays the status of compression ratio
controlled by Variable Compression
Turbo. The lowest compression ratio
(8:1) and the highest (14:1) are displayed
as “Power” and ”Eco” respectively.
2Turbo charger boost pressure gauge
Displays the turbo charger boost pres-
sure.
NOTE:
Under some conditions, the compression ra-
tio may not change. This is not a malfunction
of the system.
CAUTION
If the Variable Compression Turbo becomes
faulty, the Malfunction Indicator Light
(MIL) may come on. For additional infor-
mation, refer to “Malfunction Indicator
Light (MIL)” in this section.

2-26Instruments and controls

∙ Objects in the RearView Monitor will ap-pear visually opposite compared to when
viewed in the rearview and outside
mirrors.
∙ Use the displayed lines as a reference. The lines are highly affected by the num-
ber of occupants, fuel level, vehicle posi-
tion, road conditions and road grade.
∙ Make sure that the liftgate is securely closed when backing up.
∙ Do not put anything on the rearview camera. The rearview camera is installed
above the license plate.
∙ When washing the vehicle with high pressure water, be sure not to spray it
around the camera. Otherwise, water
may enter the camera unit causing water
condensation on the lens, a malfunction,
fire or an electric shock.
∙ Do not strike the camera. It is a precision instrument. Otherwise, it may malfunc-
tion or cause damage resulting in a fire or
an electric shock.
The following are operating limitations and
do not represent a system malfunction: ∙ When the temperature is extremely high
or low, the screen may not clearly display
objects.
∙ When strong light directly shines on the camera, objects may not be displayed
clearly.
∙ Vertical lines may be seen in objects on the screen. This is due to strong reflected
light from the bumper.
∙ The screen may flicker under fluorescent light.
∙ The colors of objects on the RearView Monitor may differ somewhat from the
actual color of objects.
∙ Objects on the monitor may not be clear in a dark environment.
∙ There may be a delay when switching between views.
∙ If dirt, rain or snow accumulate on the camera, the RearView Monitor may not
display objects clearly. Clean the camera.
∙ Do not use wax on the camera lens. Wipe off any wax with a clean cloth dampened
with a diluted mild cleaning agent, then
wipe with a dry cloth.
SYSTEM MAINTENANCE
CAUTION
∙ Do not use alcohol, benzine or thinner toclean the camera. This will cause
discoloration.

CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
∙ Keep your engine tuned up. Malfunctions in the ignition, fuel injection, or electrical
systems can cause over rich fuel flow into
the three-way catalyst, causing it to
overheat. Do not keep driving if the en-
gine misfires, or if noticeable loss of per-
formance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly. It is recommended
that you visit an INFINITI retailer for this
service.
∙ Avoid driving with an extremely low fuel level. Running out of fuel could cause the
engine to misfire, damaging the three-
way catalyst.
∙ Do not race the engine while warming it up.
∙ Do not push or tow your vehicle to start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to en-
sure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

10.Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases tire
wear and lowers fuel economy.
∙ Keep all the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer in-
formation” section of this manual. If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.

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.
