Situations in which EV drive mode cannot be turned on  
It may not be possible to turn EV drive mode on in the following situations.*  
If it cannot be turned on, a buzzer will sound and a message will be shown  
on the multi-information display.  
The temperature of the hybrid system is high.  
The vehicle has been left in the sun, driven on a hill, driven at high  
speeds, etc.  
The temperature of the hybrid system is low.  
The vehicle has been left in temperatures lower than about 32 F (0 C)  
for a long period of time etc.  
The gasoline engine is warming up.  
The hybrid battery (traction battery) is low.  
When the amount of remaining hybrid battery (traction battery) charge  
displayed on the meter is low. (P. 42)  
Vehicle speed is high.  
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.  
The windshield defogger is in use.  
*: Depending on the circumstances, EV drive mode may also not be  
switched to in situations other than those above.  
Switching to EV drive mode when the gasoline engine is cold  
If the hybrid system is started while the gasoline engine is cold, the gasoline  
engine will start automatically after a short period of time in order to warm  
up. In this case, you will become unable to switch to EV drive mode.  
After the hybrid system has started and the “READY” indicator has illumi-  
nated, press the EV drive mode switch before the gasoline engine starts to

2-1. Driving procedures  
Automatic cancelation of EV drive mode  
When driving in EV drive mode, the gasoline engine may automatically  
restart in the following situations. When EV drive mode is canceled, a buzzer  
will sound and the EV drive mode indicator will flash and go off.  
The hybrid battery (traction battery) becomes low.  
Vehicle speed becomes high.  
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.  
Possible driving distance when driving in EV drive mode  
2
In EV drive mode, it is possible to drive up to about 1.3 mile (2 km) if driving  
at a speed of about 25 mph (40 km/h) or less. (The distance that is possible  
depends on the hybrid battery [traction battery] level and driving conditions.)  
Changing a driving mode when in EV drive mode  
EV drive mode can be used in conjunction with Eco drive mode and power  
mode.  
However, EV drive mode may be automatically canceled when used in con-  
junction with power mode.  
Fuel economy  
PRIUS is designed to achieve the best possible fuel economy during normal  
driving (using the gasoline engine and electric motor [traction motor]). Driv-  
ing in EV drive mode more than necessary may lower fuel economy.  
CAUTION  
While driving  
When driving in EV drive mode, pay special attention to the area around the  
vehicle. Because there is no engine noise, pedestrians, people riding bicy-  
cles or other people and vehicles in the area may not be aware of the vehicle  
starting off or approaching them, so take extra care while driving.
