■When in EV mode
In EV mode, EV driving (driving using only the electric motor)
* is
possible. However, depending on the situation, EV driving may be
canceled and both gasoline engine and electric motor are used
(P. 104). Also, if a little electricity is remaining in the hybrid battery
(traction battery), HV mode is automatically selected. To drive in EV
mode long, observe the followings.
●Avoid sudden acceleration and sudden deceleration, and be sure
to drive smoothly.
If you repeatedly accelerate, the hybrid battery (traction battery)
charge will deplete quickly. Also, EV driving may be canceled by
rapid acceleration or vehicle speed.
●Restrain your speed as much as possible. The distance that can
be driven in EV mode will reduce considerably at high speeds.
*: The EV driving range can be checked using the multi-information dis-
play etc. (P. 225, 241, 248, 265)
■
When in EV City mode
In EV City mode, EV driving (driving using only the electric motor) is
possible.
*1
●Motor output is limited at the same level unless the accelerator
pedal is fully depressed.
When it is necessary to accelerate the vehicle, depress the
accelerator pedal completely or cancel EV City mode as needed.
●In the following situations, EV City mode is automatically can-
celed.
*2
• When driving in EV driving is not possible. (P. 104)
• When Dynamic radar cruise control with full-speed range is
activated.
• When the accelerator pedal is fully depressed.
*1: The EV driving range can be checked using the multi-information dis-
play etc. (P. 225, 241, 248, 265)
*2: Depending on the circumstances, EV City mode may also be canceled
in situations other than those above.

■When the driving assist systems are operating
When using driving assist systems such as the dynamic radar
cruise control with full-speed range (P. 451) and LTA (Lane Trac-
ing Assist) (P. 429), information related to each system is auto-
matically displayed on the multi-information display depending on
the situation.
For details regarding the displayed information and the contents of the
display, refer to the explanation page of each system.
