When the shift lever is in the S position, the shift lever can be operated as
follows:
Upshifting
Downshifting
The initial shift range in S mode is set automatically to “5” or “4” accord-
ing to vehicle speed.
■ Shift ranges and their functions
● You can choose from 6 levels of engine braking force.
● A lower shift range will provide gr eater engine braking force than a
higher shift range, and the engi ne speed will also increase.■
Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the air
conditioning system to enhance fuel efficiency. (  P. 342, 350) To improve air con-
ditioning performance, adjust the fa n speed or turn off Eco drive mode. ■
Automatic return to normal driving mode
If snow mode or sport mode is selected , the driving mode will automatically return
to normal mode when the hybrid system is turned off.
■

Hybrid System Indicator
●
By keeping the indicator within Eco area, more Eco-friendly driving can be
achieved.●
Charge area indicates regeneration* st atus. Regenerated energy will be used
to charge the hybrid battery (traction battery).
*: When used in this manual, “regeneration” refers to the conversion of energy cre-
ated by the movement of the ve hicle into electrical energy.■
ECO lamp and SPORT lamp ●
When sport mode is selected, the SPORT lamp (red) will illuminate.●
When all of the following conditions are satisfied and the Eco-friendly driving,
the ECO lamp (blue) will illuminate:
• When driving with the shift lever in D
• When either normal mode or Eco mode are selected, and EV drive mode
and snow mode are not in use
• The vehicle speed is approximately 80 mph (130 km/h) or below.
