2019 NISSAN ALTIMA Malfunction

VARIABLE COMPRESSION TURBO
(if so equipped)
Your engine is equipped with a variable
compression ratio system called “Variable
Compression Turbo”. This system can vary
the engine compression ratio continu-
ously.
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 infor-
mation, refer to “Vehicle information dis-
play” in this section.
1Compression ratio status display
Displays the status of compression ra-
tio 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 compres-
sion ratio 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, refer to “Malfunction Indi-
cator Light (MIL)” in this section.
