Fine adjustment: Momentarily
move the lever in the desired direc-
tion.
Large adjustment: Hold the lever in
the desired direction.
In the vehicle-to-vehicle distance control mode, the set speed will be
increased or decreased as follows:
XWhen the set speed is shown in “km/h”
Fine adjustment: By approximately 5 km/h (3.1 mph) each time the lever is
operated
Large adjustment: By approximately 5 km/h (3.1 mph) for each 0.75 sec-
onds the lever is held
XWhen the set speed is shown in “MPH”
Fine adjustment: By approximately 5 mph (8 km/h) each time the lever is
operated
Large adjustment: By approximately 5 mph (8 km/h) for each 0.75 seconds
the lever is held
In the constant speed control mode ( →P. 247), the set speed will be
increased or decreased as follows:
Fine adjustment: By approximately 1.6 km/h (1 mph) each time the lever is
operated
Large adjustment: The set speed can be increased or decreased continu-
ally until the lever is released.

Constant speed control mode differs from vehicle-to-vehicle distance
control mode. When constant speed control mode is selected, your
vehicle will maintain a set speed regardless of whether or not there
are other vehicles in the lane ahead.Press the “ON-OFF” button to
activate the cruise control.
Press the button again to deacti-
vate the cruise control.
Switch to constant speed con-
trol mode.
(Push the lever forward and
hold for approximately one sec-
ond.)
Cruise control indicator will come on.
When in constant speed control mode, to return to vehicle-to-vehicle dis-
tance control mode, push the lever forward again and hold for approxi-
mately 1 second.
After the desired speed has been set, it is not possible to return to vehicle-
to-vehicle distance control mode.
If the power switch is turned off and then turned to ON mode again, the
vehicle will automatically return to vehicle-to-vehicle distance control
mode.

■Dynamic radar cruise control can be set when
●The shift position is in D.
● Vehicle speed is above approximately 50 km/h (30 mph).
■ Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed
resumes. However, during vehicle-to-v ehicle distance control mode, the vehi-
cle speed may decrease below the set speed in order to maintain the dis-
tance to the vehicle ahead.
■ Set speed
The set speed may be unsustainable depending on driving circumstances.

Driving mode select switch
Eco drive mode*
Suitable for improving the fuel
economy, because the torque cor-
responding to the accelerator
pedal depression amount can be
generated more smoothly than it is
in normal conditions and the oper-
ation of the air conditioning system
(heating/cooling) will be minimized.
When the “ECO” switch is pressed, the “ECO MODE” indicator comes on
in the instrument cluster.
Power mode*
Use when high levels of response and feeling are desirable, such as when
driving in mountainous regions or when overtaking.
When the “PWR” switch is pressed, the “PWR MODE” indicator comes on
in the instrument cluster.
*: When Eco drive mode and power mode are canceled, the system uses
normal mode for optimal everyday driving.
■ 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. 286). To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■ When canceling Eco drive mode/power mode
●Press the switch again. Also, power mode will be canceled automatically
when the power switch is turned off. However, Eco drive mode will not be
canceled automatically until the switch is pressed, even if the power switch
is turned off.
● When in Eco drive mode, if the “PWR” switch is pressed or the operation is
reversed, the mode will switch to that of the last switch to be pressed.

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/cooling) will be minimized, improving
the fuel economy. (→P. 255)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the Hybrid System
Indicator within Eco area. ( →P. 118)
◆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 parking. When
using the N, there is no positive 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 hybrid
battery (traction battery) power is consumed.
◆Accelerator pedal/brake pedal operation
● Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual acceleration and deceleration will make
more effective use of the electric motor (traction motor) without
having to use gasoline engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction 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 driving, pay attention to the fol-
lowing points:

2724-6. Driving tips
PRIUS +_OM_OM47B24E_(EE)
◆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 at
traffic lights, will lead to bad fuel economy. Check traffic reports
before leaving and avoid delays as much as possible. When driving
in a traffic jam, gently release the brake pedal to allow the vehicle 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 stop-
ping at a toll booth or similar, allow plenty of time to release the
accelerator and gently apply the brakes. A greater amount of elec-
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 temperature 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 gasoline engine will not automatically cut out
until it and the interior of the vehicle are warm, it will consume fuel.
Fuel consumption can be improved by avoiding overuse of the
heater.

When the outside temperature is low
The dehumidification function may not operate even when is pressed.
■ Operation of the air conditioning system in Eco drive mode
●In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency
• Engine speed and compressor operation controlled to restrict heating/
cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations
• Adjust the fan speed
• Turn off Eco drive mode
• Customize the air conditioning control of Eco drive mode. ( →P. 480)
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air condi tioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
