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,
see “Vehicle information display” (P. 2-19).
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 gaugeDisplays the turbo charger boost pressure.
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 be-
comes faulty, the Malfunction Indicator
Light (MIL) may come on. For additional
information, see “Malfunction Indicator
Light (MIL)” (P. 2-15).

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 light does not illuminate with the
ignition switch placed in the ON position,
have the vehicle checked as soon as pos-
sible. It is recommended that you visit an
INFINITI retailer for this service.
• If the light illuminates 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. Driv-
ing with under-inflated tires may perma-
nently 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 per-
sonal injury or death. Check the tire pres-
sure for all four tires. Adjust the tire
pressure to the recommended COLD tire
pressure shown on the Tire and Loading
Information label located in the driver’s
door opening to turn the low tire pres-
sure 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 replace-
ment tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
•
When using a wheel without the TPMS
such as the spare tire, the TPMS will not
function and the low tire pressure warning
light will flash for approximately 1 minute.
The light will remain on after 1 minute.
Have your tires replaced and/or TPMS
system reset as soon as possible. It is rec-
ommended that you visit an INFINITI re-
tailer for these services.
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly. •
If the vehicle is being driven at speeds of
less than 16 mph (25 km/h), the TPMS
may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.
Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or blinks
while the engine is running, it may indicate a
potential emission control malfunction.
The MIL may also come on steady if the
fuel-filler cap is loose or missing, or if the
vehicle runs out of fuel. Check to make sure
the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3 gal-
lons (11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for
20 seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance test.
For additional information, see “Readiness for
Inspection/Maintenance (I/M) test” (P. 10-35).
Instruments and controls2-15

Master warning light
When the ignition switch is in the ON posi-
tion, the master warning light illuminates if
any of the following (if so equipped) are dis-
played on the vehicle information display:
• I-Key system warnings
• Low washer fluid warning
• Door/ liftgate open warning (when vehicleis stopped)
• Loose fuel cap warning
• Low tire pressure warning
• Flat tire warning
• Transmission system warning
• Headlight warning
• Driver Attention Support system warning
• Shipping mode warning
• All Wheel Drive (AWD) system warning
• Adaptive Front lighting System (AFS) warning
• Driving Aids malfunction warning
• Chassis Control system warning
• Engine warnings
For additional information, see “Vehicle in-
formation display” (P. 2-19).
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 sys-
tem 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 posi-
tion, the power steering warning light illumi-
nates. 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, see
“Power Steering”. (P. 5-137).
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 illumi-
nates while the engine is running, it may
indicate the electric power steering is not
functioning properly 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, see “Power Steering” (P. 5-137).
