Vehicle status information and indicators
■Rev peak (Normal mode/SPORT
S mode)
The engine speed reaches or exceeds
3600 rpm, an afterimage of the
tachometer will be displayed at the
highest engine speed for approxi-
mately 1 second.
■Meter display and layout
If the drive mode is changed, some of
the meter displays and the gauge lay-
out will be changed. ( P.192)
■The meters and display illuminate when
The engine switch is in IGNITION ON
mode.
■Welcome illumination of the analog
speedometer
●When the driver’s door is opened, the
analog speedometer will illuminate. Then,
when the driver’s door is closed, the ana-
log speedometer will illuminate and go
off (pulsate) 3 times.
●In the following situations, the analog
speedometer will not pulsate even
though the driver’s door is opened and
closed:
• Within 60 seconds after the analog
meter pulsation completes
• Within 60 seconds of turning the engine switch off
■Variable red zone
To help protect the engine, the engine
speed is controlled by starting the red zone
of the tachometer at different engine
speeds ranging from 3700 rpm to 7300
rpm depending on the engine coolant tem-
perature. Before driv ing under extremely
high load conditions, make sure to suffi-
ciently warm up the engine.
■Eco driving meter
●The number of blue segments displayed
on the eco driving meter
decreases/increases depending on the
vehicle acceleration. Use this meter as a
guideline when you wish to drive in an
eco-friendly manner that reduces fuel
consumption.
However, on a downward grade where
the vehicle can accelerate without the
accelerator pedal being depressed, the
eco driving meter may not display the
eco-driving state correctly.
●When the shift lever is moved to P, N or
R, the segments will turn gray and the eco
driving meter will not operate.
■Dimming the analog speedometer light-
ing
The analog speedometer lighting will be
dimmed when the ambient light is bright,
such as during the daytime, and SPORT S
or SPORT S+ mode is selected.
■Outside temperature display
●In the following situations, the correct
outside temperature may not be dis-
played, or the display may take longer
than normal to change:
• When stopped, or driving at low speeds (less than 12 mph [20 km/h])
• When the outside temperature has

■Eco Driving Indicator
During Eco-friendly acceleration (Eco
driving), the Eco Driving Indicator
Light will turn on.
When the acceleration exceeds the
Zone of Eco driving, or when the vehi-

Departure Alert with steering control) sys-
tem. The display is en abled when the oper-
ating conditions of the vehicle sway
warning are met. ( P.165)

*: The doors that can recall the driving position memory are changed at the
same time.
■Using automatic mode
Fan speed is adjusted automatically accord-
ing to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until
warm or cool air is ready to flow immedi-
ately after is pressed or “AUTO” is
selected.
■Using the voice command system
Air conditioning system can be operated
using voice commands. Fo r details, refer to
the “NAVIGATION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”.
■Fogging up of the windows
The windows will easily fog up when the
humidity in the vehicle is high. Turning (“A/C”) on will dehumidify the air
from the outlets and defog the windshield
effectively.
●If you turn (“A/C”) off, the win-
dows may fog up more easily.
●The windows may fog up if the recircu-
lated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the
vehicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake mode be set to outside air
mode and the fan speed to any setting
except off.
■Outside/recirculated air mode
●Setting to the recirculated air mode tem-
porarily is recommended in preventing
dirty air from entering the vehicle interior
and helping to cool the vehicle when the
outside air temperature is high.
●Outside/recirculated air mode may auto-
matically switch de pending on the tem-
perature setting or the inside
temperature.
■When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on
●In order to reduce the air conditioning
power consumption, the air conditioning
system may switch to recirculated air
mode automatically. This may also
reduce fuel consumption.
●Recirculated air mode is selected as a
default mode when the engine switch is
turned to IGNITION ON mode.
●It is possible to switch to outside air mode
at any time by pressing
.
■Automatic mode for air intake control
In automatic mode, the system detects
exhaust gas and other pollutants and auto-
matically switches between outside air and
recirculated air modes.
When the dehumidification function is off,
and the fan is operating, turning automatic
mode on will activate the dehumidification
function.
■Operation of the air conditioning sys-
tem in Eco drive mode
In Eco drive mode, the air conditioning sys-
tem is controlled as follows to prioritize fuel
efficiency:
●Engine speed and compressor operation
controlled to restrict heating/cooling
capacity
●Fan speed restricted when automatic
mode is selected
To improve air condit ioning performance,
perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode
■When the outside temperature falls to
nearly 32°F (0°C)
The dehumidification function may not
operate even when is pressed or
“A/C” is selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning
system to the outside air mode.
