COROLLA HV_Ubuzzer 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 batt
ery 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 star t automatically
after a short peri od 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 mo tor) 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 batt ery 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 tha t is possible
depends on the hybrid battery [trac-
tion battery] level a nd 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 r ange 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

COROLLA HV_U
The system can detect the fol-
lowing:
Vehicles
 Bicyclists
 Pedestrians
■Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the
multi-information display to urge
the driver to take evasive action.
■Pre-collision brake assist
When the system determines
that the possibility of a frontal
collision is high, the system
applies greater braking force in
relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
If the system determines that
the possibility of a frontal colli-
sion is extremely high, the
brakes are automatically applied
to help avoid the collision or
reduce the impact of the colli-
sion.
PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects ( P.177) in front of
the vehicle. When the sys-
tem determines that the
possibility of a frontal colli-
sion with an object is high, a
warning operates to urge
the driver to take evasive
action and the potential
brake pressure is increased
to help the driver avoid the
collision. If the system
determines that the possi-
bility of a frontal collision
with an object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.
The pre-collision system
can be disabled/enabled
and the warning timing can
be changed. ( P.176)
