■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.

Displays the estimated maximum distance that can
be driven with the quantity of fuel remaining.
• This distance is computed based on your average
fuel consumption. As a result, the actual distance
that can be driven may differ from that displayed.
• When only a small amount of fuel is added to the
tank, the display may not be updated.
Displays the average fuel consumption since the
function was reset.
The function can be reset by pushing the “DISP” switch

AFS (Adaptive Front lighting System)
AFS improves visibility at intersections and on curves by automatically
adjusting the level of the headlights according to vehicle speed and the
degree of the tire angle that are controlled by steering input.
Operates at speeds of 6 mph (10 km/h) or higher.
■Deactivating AFS
Press the switch to turn it off.
The indicator turns on when
the AFS is deactivated.
■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on auto-
matically (at a reduced intensity) whenever the hybrid system is started and the
parking brake is released. Daytime running lights are not designed for use at
night.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel
economy.
