Situations in which EV drive

mode cannot be turned on

It may not be possible to turn EV

drive mode on in the following situa-

tions. If it cannot be turned on, a

buzzer will sound and a message

will be shown on the multi-informa-

tion display.

●

The temperature of the hybrid sys-

tem is high.

The vehicle has been left in the

sun, driven on a hill, driven at high

speeds, etc.

●

The temperature of the hybrid sys-

tem is low.

The vehicle has been left in tem-

peratures lower than about 68°F

(20°C) for a long period of time

etc.

●

●

The accelerator pedal is

depressed firmly or the vehicle is

on a hill etc.

●

The windshield defogger is in use.

Use the EV drive mode when it
becomes available.

■

Switching to EV drive mode

when the gasoline engine is

cold

If the hybrid system is started while

the gasoline engine is cold, the gas-

oline 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 illuminated,

press the EV drive mode switch

before the gasoline engine starts to

switch to EV drive mode.

■

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, the EV drive

mode indicator will flash and go off

and a message will be shown on the

multi-information display.

●

The hybrid battery (traction bat-

tery) becomes low.

The remaining battery level indi-

cated in the Energy monitor dis-

play is low. (

P.122)

●

Vehicle speed is high.

●

The accelerator pedal is

depressed firmly or the vehicle is

on a hill etc.

Drive the vehicle for a while before

attempting to turn on the EV drive

mode again.

■

Possible driving distance when

driving in EV drive mode

EV drive mode’s possible driving

distance ranges from a few hundred

meters to approximately 0.6 mile (1

km). However, depending on vehi-

cle conditions, there are situations

when EV drive mode cannot be

used.

(The distance that is possible

depends on the hybrid battery [trac-

tion battery] level and driving condi-

tions.)

■

Fuel economy

The hybrid system is designed to

achieve the best possible fuel econ-

omy during normal driving (using

the gasoline engine and electric

motor [traction motor]). Driving in

EV drive mode more than neces-

sary may lower fuel economy.

■

If “EV Mode Unavailable” is

shown on the multi-information

display

The EV drive mode is not available.

The reason the EV drive mode is

not available (the vehicle is idling,

241

4-2. Driving procedures

battery charge is low, vehicle speed

is higher than the EV drive mode

operating speed range or accelera-

tor pedal is depressed too much)

may be displayed. Use the EV drive

mode when it becomes available.

■

If “EV Mode Deactivated” is

shown on the multi-information

display

The EV drive mode has been auto-

matically canceled. The reason the

EV drive mode is not available (the

battery charge is low, vehicle speed

is higher than the EV drive mode

operating speed range or accelera-

tor pedal is depressed too much)

may be displayed. Drive the vehicle

for a while before attempting to turn

on the EV drive mode again.

:To improve fuel efficiency and

reduce noise, shift the shift lever
to D for normal driving.

:By selecting shift ranges using S

mode, you can control accelerat-
ing force and engine braking
force.

■

When driving with dynamic

radar cruise control with full-

speed range activated

Even when performing the following

actions with the intent of enabling

engine braking, engine braking will

not activate because dynamic radar

cruise control with full-speed range

will not be canceled.

●

While driving in S mode, down-

shifting to 5 or 4. (

■

Caution while driving

When driving in EV drive mode,

pay special attention to the area

around the vehicle. Because

there is no engine noise, pedestri-

ans, people riding bicycles 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. Therefore, take extra care

while driving even if the Acoustic

Vehicle Alerting System is active.

The selected shift range, from S1 to
S6, will be displayed on the multi-
information display.

The initial shift range in S mode
is set automatically to S4 or S5
according to vehicle speed.

■

S mode

●

You can choose from 6 levels of

accelerating force and engine

braking force.

●

A lower shift range will provide

greater accelerating force and

engine braking force than a higher

shift range, and the engine revolu-

tions will also increase.

●

To prevent the engine from over-

revving, upshifting may automati-

cally occur when the shift range is

4 or lower.

●

When the shift range is 4 or lower,

holding the shift lever toward “+”

sets the shift range to 6.

■

Downshifting restriction warn-

ing buzzer
