*: To improve fuel efficiency and reduce noises, set the shift lever in the D
position for normal driving.
Suitable for enhancing the fuel economy, because the torque cor re-
sponding to the accelerator pedal depression amount can be gene r-
ated more smoothly than it is in normal conditions and the oper ation
of the air conditioning system ( heating/cooling) will be minimized.
Eco drive mode
When Eco drive mode is turned on,
the “ECO MODE” indicator will
come on.
Pressing the Eco drive mode
switch again turns Eco drive mode
off.
■ 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. 376) To improve air
conditioning performance, adjust the temperature setting or fan speed, or turn
off Eco drive mode.
■ When the accelerator p edal is depressed while the shift position is in N
A buzzer will sound to inform the driver that the shift positio n is in N.

4-7. 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. 203)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the needle of H ybrid
System Indicator within Eco area. ( P. 110)
◆Shift lever operation
Shift the shift lever to D when stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift lever to P when parking. When using
the N, there is no positive effe ct on fuel consumption. In the N, the
gasoline engine operates but e lectricity cannot be generated. A lso,
when using the air conditioning s ystem, etc., the hybrid battery
(traction battery) 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.
◆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.
Hybrid vehicle driving tips
For economical and ecological dri ving, pay attention to the fol-
lowing points:

PRIUS c_U
WARNING
■Replacing a flat tire
●Do not touch the disc wheels or the area around the brakes immedi-
ately after the vehi cle has been driven.
After the vehicle has been driven the disc wheels and the area around
the brakes will be extremely hot. Touching these areas with hands, feet
or other body parts while changin g a tire, etc. may result in burns.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the t ire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened wit h a torque wrench to 76 ft•lbf (103
N•m, 10.5 kgf•m) as soon as po ssible after changing wheels.
• Do not attach a heavily damaged wheel ornament, as it may fly off
the wheel while the vehicle is moving.
• When installing a tire, only use wheel nuts that have been spe cifi-
cally designed for that wheel.
• If there are any cracks or defo rmations in the bolt screws, nut
threads or bolt holes of the wheel, have the vehicle inspected by
your Toyota dealer.
• When installing the wheel nuts, b e sure to install them with the
tapered ends facing inward. ( P. 448)
