■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at
least enough gasoline to make the
low fuel level warning light ( P.481)
go off. If there is only a small amount of fuel, the hybrid system
may not be able to
start. (The stan-
dard amount of fuel is about 2.0 gal.
[7.6 L, 1.7 I mp. gal.] when the vehi-
cle is on a level surface. This value
may vary when the v ehicle is on a
slope. Add extra fu el when the vehi-
cle is inclined.)
Hybrid system precautions
Take care when handling the hybrid system, as it is a high
voltage system (about 600 V at maximum) as well as contains
parts that become extremely hot when the hybrid system is
operating. Obey the warning labels attached to the vehicle.

■If a warning message is displayed on the multi-information disp lay
A system may be tempor arily unavailable or there may be a malfu nction in
the system.
●In the following situations, perform the actions specified in t he table. When
the normal operating conditions are detected, the message will disappear
and the system will be come operational.
If the message does not disapp ear, contact your Toyota dealer.
SituationActions
When the area around a sensor is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterTo clean the part of the windshield in
front of the front camera, use the
windshield wipers or the windshield
defogger of the air conditioning sys-
tem ( P.387)

1884-5. Using the driving support systems
COROLLA HV_U
●In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disapp ear, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an e xtremely cold
environment
• When the front camera cannot d etect objects in front of the vehicle, such
as when driving in the dark, sno w, or fog, or when bright lights are shining
into the front camera
When the temperature around the
front camera is out side of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight r eflected from the
surface of the sunshade may cause
the temperature of the front camera
to become exce ssively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the windshield in front
of the front camera.
Close the hood, remove the sticker,
etc. to clear the obstruction.

Driving
Each time the switch is pressed, the
system changes between power
mode, normal mode and Eco drive
mode.
1 Normal mode
Provides an optimal balance of fuel
economy, quietness, and dynamic
performance. Suitable for normal
driving.
2Power mode
Controls the hybrid system to pro-
vide quick, powerful acceleration.
Making it suitable for when agile
driving response is desired, such
as when driving on roads with many
curves.
When the power mode is selected,
power mode indicator comes on.
3Eco drive mode
Helps the driver a ccelerate in an
eco-friendly manner and improve
fuel economy through moderate
throttle characteri stics and by con- trolling the operation of the air con-
ditioning system (heating/cooling).
When the Eco drive mode is
selected, Eco drive mode indicator
comes on.
■Operation of the air condition-
ing system in Eco drive mode
Eco drive mode con trols the heat-
ing/cooling operations and fan
speed of the air conditioning system
to enhance fuel efficiency. To
improve air conditioning perfor-
mance, perform the following opera-
tions:
●Turn off eco air conditioning mode
(  P.388)
●Adjust the fan speed ( P.386)
●Turn off Eco drive mode
■The driving mode after turning
the power switch off
The driving mode will not be
changed automatically until the
switch is pressed, even if the power
switch is turned off.

The driving modes can be
selected to suit driving con-

Driving
4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving the fuel
economy. ( P.239)
The Eco-friendly driving is pos-
sible by keeping the indicate of
Hybrid System Indicator within
Eco area. ( P.105)
Shift the shift lever to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift lever to P when parking.
When using the N, there is no
positive effect on fuel consump-
tion. In the N, the gasoline
engine operates but electricity
cannot be generated. Also,
when using the air conditioning system, etc., the hybrid battery
(traction battery) power is con-
sumed.

Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration and deceleration will
make more effective use of
the electric motor (traction
motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (trac-
tion battery) power, resulting
in poor fuel consumption. Bat-
tery power can be restored by
driving with the accelerator
pedal slightly released.
Make sure to operate the brakes
gently and in a timely manner. A
greater amount of electrical
energy can be regenerated
when slowing down.
Repeated acceleration and
deceleration, as well as long
waits at traffic lights, will lead to
bad fuel economy. Check traffic
reports before leaving and avoid
delays as much as possible.

For economical and ecolog-
ical driving, pay attention to
the following points:
Using Eco drive mode
Use of Hybrid System
Indicator

2464-6. Driving tips
COROLLA HV_U
When driving in a traffic jam,
gently release the brake pedal
to allow the vehicle to move for-
ward slightly while avoiding
overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consump-
tion.
Control and maintain the vehicle
at a constant speed. Before
stopping at a toll booth or simi-
lar, allow plenty of time to
release the accelerator and gen-
tly apply the brakes. A greater
amount of electrical energy can
be regenerated when slowing
down.
Use the air conditioning only
when necessary. Doing so can
help reduce excessive gasoline
consumption.
In summer: When the ambient
temperature is high, use the
recirculated air mode. Doing so
will help to reduce the burden on
the air conditioning system and
reduce fuel consumption as
well.
In winter: Because the gasoline
engine will not automatically cut
out until it and the interior of the
vehicle are warm, it will con-
sume fuel. Also, fuel consump-
tion can be improved by avoiding overuse of the heater.
Make sure to check the tire infla-
tion pressure frequently.
Improper tire inflation pressure
can cause poor fuel economy.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads can lead to
poor fuel economy. Use tires
that are appropriate for the sea-
son.
Carrying heavy luggage will lead
to poor fuel economy. Avoid car-
rying unnecessary luggage.
Installing a large roof rack will
also cause poor fuel economy.
Since the gasoline engine starts
up and cuts out automatically
when cold, warming up the
engine is unnecessary. More-
over, frequently driving short
distances will cause the engine
to repeatedly warm up, which
can lead to excess fuel con-
sumption.

when giving a command.
●Voice commands may not be rec-
ognized if:
• Spoken too quickly.
• Spoken at a low or high volume.
• The windows are open.
• Passengers are talking while voice commands are spoken.
• The fan speed of the air condition-
ing system is set at high.
• The air conditioning vents are turned towards the microphone.
●In the following c onditions, the
system may not recognize the
command properly and using
voice commands may not be pos-
sible:
• The command is incorrect or unclear. Note that certain words,
accents or speech patterns may
be difficult for the system to recog-
nize.
• There is excessive background
noise, such as wind noise.
●Normally, it is necessary to wait
for a beep before saying a com-
mand. To enable th e ability to talk
over prompts and say commands
before the beep, enable the voice
prompt interrupt function.
