NOTE
Even though the distance-to-empty
display may indicate a sufficient amount
of remaining driving distance before
refueling is required, refuel as soon as
possible if the fuel level is very low or
the low fuel warning light illuminates.
The display may not change unless you
add more than approximately 9 L (2.3
US gal, 1.9 Imp gal) of fuel.
The distance-to-empty is the
approximate remaining distance the

graduation marks in the fuel gauge
(indicating the remaining fuel supply)
disappear.
If there is no past fuel economy
information such as after first
purchasing your vehicle or the
information is deleted when the battery
cables are disconnected, the actual
distance-to empty/range may differ from
the amount indicated.
Average fuel economy mode
This mode displays the average fuel
economy by calculating the total fuel

consumption and the distance traveled.
Current fuel economy will be calculated
and displayed every 2 seconds.
When you've slowed to about 5 km/h (3
mph), - - - L/100 km (- - - mpg) will be
displayed.

WARNING
Always adjust the display brightness and position with the vehicle stopped:
Adjusting the display brightness and position while driving the vehicle is dangerous as
doing so could distract your attention from the road ahead and lead to an accident.
CAUTION
Do not try to adjust the angle or open/close the active driving display manually.
Fingerprints on the display will make it difficult to view and using excessive force when
operating it could cause damage.
Do not place objects in the vicinity of the active driving display. The active driving display
may not operate or any interference with its operation could cause damage. Do not place beverages near the active driving display. If water or other liquids are splashed
on the active driving display, it could cause damage. Do not place objects above the active driving display screen or apply stickers to the
combiner as they will cause interference. A sensor is int
egrated to control the display's luminosity. If the optical receiver is covered,
the display's luminosity will lower making the display difficult to view. Do not allow intense light to hit the optical receiver. Otherwise, it could cause damage.
NOTE
It may be difficult to view the display when wearing sunglasses. Take off your sunglasses
or adjust the luminosity. If the battery has been removed and re-installed or the battery voltage is low, the adjusted
position may deviate. The display may be difficult to view or temporarily affected by weather conditions such as
rain, snow, light, and temperature. If the audio system is removed, the active driving display cannot be operated.
