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.

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.

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current veh i-
cle-to-vehicle following distance, and operates to maintain a s uitable
following distance from the vehicle ahead. The desired vehi-
cle-to-vehicle distance can also be set by operating the vehi-
cle-to-vehicle distance switch.
When driving on downhill slopes, t he vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not pe rformed, system
control continues to keep your vehicle stopped.
