COROLLA HV_U
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 32°F
(0°C ) for a long period of time etc.
●
The gasoline engine is warming
up.
●
The hybrid battery (traction bat-
tery) is low.
The remaining battery level indi-
cated in the energy monitor dis-
play is low. (P.9 8)
●
Vehicle speed is high.
●
The accelerator pedal is
depressed firmly or the vehicle is
on a hill etc.
●
The windshield defogger is in use.
■
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 illu-
minated, 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 start automati-
cally and the vehicle may be driven
by the gasoline engine and electric
motor (traction motor) in the follow-
ing situations. When EV drive mode
is canceled, a buzzer will sound, the
EV drive mode indicator will flash,
and a message will be displayed 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. 98 )
●
Vehicle speed is high.
●
The accelerator pedal is
depressed firmly or the vehicle is
on a hill etc.
■
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 vehicle
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,
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-
