341-1. Hybrid system
Hybrid system precautions Take care when handling the hybrid sy stem, as it contains a high voltage
system (about 650 V at maximum) as well as parts that become extremely
hot when the hybrid system is operat ing. Obey the caution labels attached
to the vehicle.

4911-1. Hybrid system
Before driving Hybrid vehicle driving tips For economical and ecological driving, pay attention to the following
points:
■ Use of Hybrid System Indicator More Eco-friendly driving is possib le by keeping the indicate of Hybrid
System Indicator within Eco area.
■ When braking the vehicle Make sure to operate the brakes ge ntly and in good time. A greater
amount of electrical energy can be retained when slowing down.
■ Delays Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fu el consumption. Check traffic reports before leav-
ing and avoid delays as much as possible. When encountering a delay,
gently release the brake pedal to allow the vehicle to move forward slightly
while avoiding overuse of the accelerato r pedal. Doing so can help control
excessive gasoline consumption.
■ Highway driving Control your speed and keep at a constant speed. Also, before stopping at
a toll booth or similar, allow plenty of time to release the accelerator and
gently apply the brakes. A greater amount of electrical energy can be
retained when slowing down.
■ Air conditioning Use the air conditioning only when necessary. Doing so can help control
excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode. Doing so
will help to reduce the burden on the air conditioning and reduce fuel con-
sumption as well.
In winter: Because the gasoline engine will not automatically cut out until
the gasoline engine and the interior of the vehicle are warm, it will con-
sume fuel. Also, fuel consumption can be improved by avoiding overuse of
the heater.

1902-1. Driving procedures
Changing shift ranges in S mode
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.
■
S mode
●
When the shift range is “5” or lower, holding the shift lever toward “+” sets the
shift range to “6”.
●
To prevent the engine from over-revving, upshifting may automatically occur.
