F SPORT models: When sport mode is select ed for the driving mode, the periphery
of the tachometer will change color and th e scale of the tachometer will be empha-
sized.
Outside temperature Displays the outside temperature within the range of -40°F (-40°C) to 122°F
(50°C). Low outside temperature indicator comes on when the ambient temperature
is 37°F (3°C) or lower.

Engine coolant temperature gauge Displays the engine coolant temperature. If the engine coolant temperature gauge
indicator ( ) enters the red zone, a buzzer will sound and the indicator will turn red
and start flashing. Also, a warning message will be displayed.
Engine oil temperature gauge Displays the engine oil temperature. If the engine oil temperature gauge indicator
( ) enters the red zone, the indicator will turn red and start flashing.
Outside temperature Displays the outside temperature within the range of -40°F (-40°C) to 122°F
(50°C). Low outside temperature indicator comes on when the ambient temperature
is 37°F (3°C) or lower.
Tachometer Displays the engine speed in revolutions per minute

Odometer and trip meter display Odometer:
Displays the total distance the vehicle has been driven
Trip meter:
Displays the distance the vehi cle has been driven since the meter was last reset. Trip
meters “A” and “B” can be used to record and display different distances inde-
pendently.
Eco driving meter Displays the vehicle acceleration. The more rapidly the vehicle is accelerated, the
lower the number of blue segments displayed, indicating that your driving is less eco-
friendly. This meter is designed as a guideline to show the eco-friendliness of your
driving. 1

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, th e analog speedometer will illuminate.
Then, when the driver’s door is closed, the analog spee dometer will illuminate and go
off (pulsate) 3 times. ●
In the following situations, the analog sp eedometer will not pulsate even though the
driver’s door is opened and closed:
• Within 60 seconds after the an alog meter pulsation completes
• Within 60 seconds of turning the engine switch off ■
Variable red zone
■
Eco driving meter ●
The number of blue segments displayed on the eco driving meter decreases/increases
depending on the vehicle acceleration. Use th is 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 ve hicle can accelerate without the acceler-
ator pedal being depressed, the eco driv ing 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 driv-
ing meter will not operate.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 temperature.
Before driving under extremely high load condi-
tions, make sure to su fficiently warm up the
engine.
