Be sure to check with your Toy-
ota dealer for precautionary
measures or special instructions
regarding installation of a mobile
two-way radio system.
High voltage parts and cables
on the hybrid vehicles emit
approximately the same amount
of electromagnetic waves as the
conventional gasoline powered
vehicles or home electronic
appliances despite of their elec-
tromagnetic shielding.
Unwanted noise may occur in
the reception of the mobile
two-way radio.
The vehicle is equipped with
sophisticated computers that will
record certain data, such as:
The recorded data varies
according to the vehicle grade
level and options with which it is
equipped.
These computers do not record
conversations or sounds, and
only record images outside of
the vehicle in certain situations.
• Engine speed/Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed • Operation status of the driving
assist systems, such as the
ABS and pre-collision system
• Images from the front camera (available only when certain
safety systems are activated,
which varies depending on
the vehicle specifications).
 Data Transmission
Your vehicle may transmit the data
recorded in these computers to
Toyota without notification to you.
Data usage
Toyota may use the data recorded
in this computer to diagnose mal-
functions, conduct research and
development, and improve quality.
Toyota will not disclose the
recorded data to a third party
except:
• With the consen t of the vehicle
owner or with the consent of the
lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehi-
cle or vehicle owner
 Recorded image information
can be erased by your Toyota
dealer.
The image recording function can
be disabled. However, if the func-
tion is disabled, data from when the
pre-collision system operates will
not be available.

COROLLA HV_Uspeed that is displayed may differ
even when vehicle operation and
driving conditions are the same.
■Outside temperature display
●In the following si
tuations, the cor-
rect outside tempe rature may not
be displayed, or the display may
take longer than normal to
change:
• When stopped, or driving at low speeds (less than 16 mph [25
km/h])
• When the outside temperature has changed su ddenly (at the
entrance/exit of a garage, tunnel,
etc.)
●When “--” or “E” is displayed, the
system may be malfunctioning.
Take your vehicle to your Toyota
dealer.
■Liquid crystal display
 P. 8 9
■Customization
The gauges and met ers can be cus-
tomized in of the multi-informa-
tion display. ( P. 9 4 )
■Changing the display
Press the display change button
until the desired item is dis-
played.
■Display items
 Odometer
Displays the total distance the vehi-
cle has been driven.
 Trip meter A/Trip meter B
Displays the distance the vehicle
has been driven since the meter
was last reset. Trip meters A and B
can be used to record and display
WA R N I N G
■The information display at
low temperatures
Allow the interior of the vehicle to
warm up before u sing the liquid
crystal informat ion display. At
extremely low temperatures, the
information display monitor may
respond slowly, and display
changes may be delayed.
For example, there is a lag
between the driver’s shifting and
the new gear number appearing
on the display. This lag could
cause the driver to downshift
again, causing rapid and exces-
sive engine braking and possibly
an accident resulting in death or
injury.
NOTICE
■To prevent damage to the
engine and its components
●Do not let the indicator needle
of the tachometer enter the red
zone, which indicates the maxi-
mum engine speed.
●The engine may be overheating
if the engine coolant tempera-
ture gauge is in the red zone
(H). In this case, immediately
stop the vehicle in a safe place,
and check the engine after it
has cooled completely.

■When starting the vehicle
Always keep your foot on the
brake pedal while stopped with
the “READY” indi cator is illumi-
nated. This prevents the vehicle
from creeping.
■When driving the vehicle
●Do not drive if y ou are unfamil-
iar with the location of the brake
and accelerator pedals to avoid
depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the
brake pedal will result in sudden
acceleration that may lead to an
accident.
• When backing up, you may twist your body around, leading to a
difficulty in operating the pedals.
Make sure to operate the pedals
properly.
• Make sure to keep a correct driving posture even when mov-
ing the vehicle only slightly. This
allows you to depress the brake
and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the
brake pedal using your left foot
may delay respon se in an emer-
gency, resulting in an accident.
●The driver should pay extra
attention to pedestrians when
the vehicle is p owered only by
the electric motor (traction
motor). As there is no engine
noise, the pedestrians may mis-
judge the vehicle’s movement.
Even with the vehicle proximity
notification system activate,
drive with care as pedestrians in
the vicinity may s till not notice
the vehicle if t he surrounding
area is noisy.
●Do not drive the vehicle over or
stop the vehicle near flammable
materials.
The exhaust system and
exhaust gases can be
extremely hot. These hot parts
may cause a fire i f there is any
flammable material nearby.
●During normal driving, do not
turn off the hybrid system. Turn-
ing the hybrid s ystem off while
driving will not cause loss of
steering or braking control, how-
ever, power assist to the steer-
ing will be lost. This will make it
more difficult to steer smoothly,
so you should pull over and stop
the vehicle as soon as it is safe
to do so.
In the event of a n emergency,
such as if it becomes impossible
to stop the vehicle in the normal
way:
P. 4 4 3
●Use engine braking (shift posi-
tion B) to maintain a safe speed
when driving down a steep hill.
Using the brakes continuously
may cause the brakes to over-
heat and lose effectiveness.
(
P.149)
●Do not adjust the positions of
the steering wheel, the seat, or
the inside or outside rear view
mirrors while driving.
Doing so may result in a loss of
vehicle control.
●Always check that all passen-
gers’ arms, heads or other parts
of their body are not outside the
vehicle.

Driving
WA R N I N G
●Do not drive in excess of the
speed limit. Even if the legal
speed limit permits it, do not
drive over 85 mph (140 km/h)
unless your vehicle has
high-speed capabilit y tires. Driv-
ing over 85 mp h (140 km/h)
may result in tire failure, loss of
control and possible injury. Be
sure to consult a tire dealer to
determine whether the tires on
your vehicle are high-speed
capability tires or not before
driving at such speeds.
■When driving on slippery
road surfaces
●Sudden braking, acceleration
and steering may cause tire
slippage and reduce your ability
to control the vehicle.
●Sudden acceleration, engine
braking due to shifting, or
changes in engine speed could
cause the vehicle to skid.
●After driving through a puddle,
lightly depress the brake pedal
to make sure that the brakes
are functioning properly. Wet
brake pads may prevent the
brakes from functioning prop-
erly. If the brakes on only one
side are wet and not functioning
properly, steering control may
be affected.
■When shifting the shift lever
●Do not let the vehicle roll back-
ward while a forward driving
position is selected, or roll for-
ward while the shift lever is in R.
Doing so may result in an acci-
dent or damage to the vehicle.
●Do not shift the shift lever to P
while the vehicle is moving.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the sh ift lever to R
while the vehicle is moving for-
ward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift lever to a
driving position while the vehicle
is moving backward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Moving the shift lever to N while
the vehicle is moving will disen-
gage the hybrid system. Engine
braking is not a vailable with the
hybrid system disengaged.
●Be careful not to shift the shift
lever with the accelerator pedal
depressed. Shifting the shift
lever to any positions other than
P or N may lead to unexpected
rapid acceleration of the vehicle
that may cause an accident and
result in death or serious injury.
■If you hear a squealing or
scraping noise (brake pad
wear indicators)
Have the brake pads checked and
replaced by your Toyota dealer as
soon as possible.
Rotor damage may result if the
pads are not replaced when
needed.
It is dangerous to drive the vehicle
when the wear limits of the brake
pads and/or those of the brake
discs are exceeded.
■When the vehicle is stopped
●Do not depress the accelerator
pedal unnecessarily.
If the shift lever is any position
other than P or N, the vehicle
may accelerate suddenly and
unexpectedly, causing an acci-
dent.

Cargo capacity depends on the
total weight of the occupants.
(Cargo capacity) = (Total load
capacity) — (Total weight of
occupants)
Steps for Determining Correct
Load Limit —
(1) Locate the statement “The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs.” on your
vehicle’s placard.
(2) Determine the combined
weight of the driver and passen-
gers that will be riding in your
vehicle.
(3) Subtract the combined
weight of the driver and passen-
gers from XXX kg or XXX lbs.
(4) The resulting figure equals
the available amount of cargo
and luggage load capacity.
For example, if the “XXX”
amount equals 1400 lbs. and
there will be five 150 lb passen-
gers in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs. (1400 −
NOTICE
■If you get a flat tire while driv-
ing
A flat or damaged tire may cause
the following situations. Hold the
steering wheel firmly and gradu-
ally depress the brake pedal to
slow down the vehicle.
●It may be difficult to control your
vehicle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnor-
mally.
Information on what to do in case
of a flat tire (
P.473)
■When encountering flooded
roads
Do not drive on a road that has
flooded after heavy rain etc.
Doing so may cause the following
serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by
water immersion
In the event that you drive on a
flooded road an d the vehicle
becomes flooded or stuck in mud
or sand, be sure to have your Toy-
ota dealer check the following:
●Brake function
●Changes in quantity and quality
of oil and fluid used for the
engine, hybrid transmission,
etc.
●Lubricant condition for the bear-
ings and suspension joints
(where possible), and the func-
tion of all joints , bearings, etc.

:While the power switch is in
ON and the brake pedal
depressed
*, shift the shift lever
while pushing the shift release
button on the shift knob.
:Shift the shift lever while
pushing the shift release button
on the shift knob. :Shift the shift lever normally.
When shifting the shift lever
between P and D, make sure that
the vehicle is completely stopped.
*: For the vehicle be able to be
shifted from P, the brake pedal
must be depressed before the
shift release button is pushed. If
the shift release button is pushed
first, the shift lock will not be
released.
■Shift lock system
The shift lock syste m is a system to
prevent accidental operation of the
shift lever in starting.
The shift lever can be shifted from P
only when the power switch is in ON
and the brake pedal is being
depressed.
■If the shift lever cannot be
shifted from P
First, check whether the brake pedal
is being depressed.
If the shift lever cannot be shifted
with your foot on the brake pedal,
there may be a p roblem with the
shift lock system. Have the vehicle
inspected by your Toyota dealer
immediately.
The following steps may be used as
an emergency measure to ensure
that the shift lev er can be shifted.
Releasing the shift lock:
1 Set the parking brake.
2 Turn the power switch off.
3 Depress the brake pedal.
4 Ply the cover up with a flathead
screwdriver or equivalent tool.
To prevent damaging the cover,
NOTICE
■Hybrid battery (traction bat-
tery) charge
If the shift lever is in N, the hybrid
battery (traction battery) will not
be charged even when the engine
is running. Theref ore, if the vehi-
cle is left with th e shift lever in N
for a long period of time, the
hybrid battery (tr action battery)
will discharge, and this may result
in the vehicle n ot being able to
start.

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.219)
The Eco-friendly driving is pos-
sible by keeping the indicate of
Hybrid System Indicator within
Eco area. ( P.91)
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.
