TEMPERATURE GAUGE
The gauge indicates the engine coolant tem-
perature. The engine coolant temperature is
within the normal range
1when the gauge
needle points within the zone shown in the
illustration.
The engine coolant temperature varies with
the outside air temperature and driving con-
ditions.
CAUTION
If the gauge indicates coolant temperature
near the hot (H) end of the normal range,
reduce vehicle speed to decrease tempera-
ture. If the gauge is over the normal range,
stop the vehicle as soon as safely possible. If
the engine is overheated, continued opera-
tion of the vehicle may seriously damage
the engine. For additional information, re-
fer to “If your vehicle overheats” in the “In

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.
