Hybrid vehicle driving tips
◆Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/coo ling) will be minimized, improving
the fuel economy. ( P. 347)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the Hybrid Syst em
Indicator within Eco area. ( P. 129)
◆Shift position operation
Shift the shift position to D when stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift position to P when parkin g. When
using the N, there is no positiv e effect on fuel consumption. In the
N, the gasoline engine operates but electricity cannot be gener -
ated. Also, when using the air conditioning system, etc., the h ybrid
battery (traction batt ery) power is consumed.
◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual accelerat ion and deceleration will make
more effective use of the electric motor (traction motor) witho ut
having to use gaso line engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (tracti on battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
For economical and ecological dri ving, pay attention to the fol-
lowing points:

4-6. Driving tips
◆When braking
Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits a t
traffic lights, will lead to bad fuel economy. Check traffic re ports
before leaving and avoid delays as much as possible. When drivi ng
in a traffic jam, gently release the brake pedal to allow the v ehicle to
move forward slightly while avoiding overuse of the accelerator
pedal. Doing so can help control excessive gasoline consumption.
◆Highway driving
Control and maintain the vehicle at a constant speed. Before st op-
ping at a toll booth or similar, allow plenty of time to releas e the
accelerator and gently apply the brakes. A greater amount of el ec-
trical energy can be regenerated when slowing down.
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient tempe rature is high, use the recircu-
lated air mode. Doing so will help to reduce the burden on the air
conditioning system and reduce fuel consumption as well.
In winter: Because the gasolin e engine will not automatically cut out
until it and the interior of the vehicle are warm, it will cons ume fuel.
Also, fuel consumption can be improved by avoiding overuse of t he
heater.

Press .
The cooling and dehumidificati on function switches between on a nd

To stop the operation, press .
■Automatic mode indicator
If the fan speed setting or air flow modes are operated, the
indicator goes off. However, automatic mode for functions other
than that operat ed is maintained.
This function automatically contro ls the air conditioning airflow so that
priority is given to the front seats. When the front passenger seat is
not occupied, airflow may switch to only the driver’s seat. Unn eces-
sary air conditioning is suppressed, contributing to increased fuel effi-
ciency.
Front seat concentrated airflow mode operates in the following situa-
tions.
● No passengers are dete cted in the rear seats
● The windshield defogger is not operating
While operating, illuminates.
