fuel consumption TOYOTA VERSO S 2011 Owners Manual

902-1. Plug-in hybrid system
Moreover, as fuel consumption is
also reduced when in HV mode, the
regenerative braking system can be
used effectively.
■Regenerative braking
In the following situations, kinetic energy
is converted to electric energy and
deceleration force can be obtained in
conjunction with the recharging of the
hybrid battery (traction battery).
●The accelerator pedal is released
while driving with the shift lever in D or
S.
●The brake pedal is depressed while
driving with the shift lever in D or S.
■EV driving range
●The EV driving range is displayed on
the multi-information display.
(P.181)
●The EV driving range changes in
accordance with the charge status of
the hybrid battery (traction battery),
the speed of the vehicle, etc.
●Even if there is enough charge
remaining in the hybrid battery (trac-
tion battery), EV driving may be can-
celed and both gasoline engine and
electric motor are used depending on
the situation. (P.90)
■EV indicator
The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.The on/off operation
of the EV indicator can be changed.
(P.186)
■After EV mode has switched to HV
mode due to low hybrid battery
(traction battery) charge
If the hybrid battery (traction battery) is
regenerated by driving continuously
down a long slope, the EV driving range
etc. will be displayed on the multi-infor-
mation display and EV mode will be
automatically switched to.
If EV mode is not switched to even
though EV driving range is being dis-
played, EV mode can be switched to by
pressing the EV/HV mode selection
switch.
■Gasoline engine operation in EV
mode or AUTO EV/HV mode
Even if there is a sufficient amount of
electricity remaining in the hybrid battery
(traction battery) and EV driving range
(P.181) is being displayed on the
multi-information display, EV driving
(driving using only the electric motor)
may be canceled and both gasoline
engine and electric motor are used
depending on the situation (EV driving
will be returned to automatically after EV
driving becomes possible again).
EV driving may be canceled automati-
cally in the following circumstances
*1:
●When vehicle speed is more than
approximately 135 km/h (84 mph).
●When power is needed temporarily,
for example when the accelerator
pedal is depressed firmly or when
accelerating suddenly.
*2
●When the temperature of the hybrid
system is high.
The vehicle has been left in the sun,
driven on a hill, driven at high speeds,
etc.
●When the temperature of the hybrid
system is low.
●When the heater is switched on when
the outside temperature is below
about -10°C (14°F).
●When the windshield defogger switch
is pressed. (P.453)
●When the system determines that the

922-1. Plug-in hybrid system
hybrid battery (traction battery)
from an external power source
before using the vehicle.
Even if charging the hybrid battery
(traction battery) has not been com-
pleted, the vehicle can be driven. How-
ever, if there is not enough charge
remaining, it is possible that the vehicle
cannot be driven in EV mode or AUTO
EV/HV mode, or the EV driving range
will become shorter.
■Refilling fuel
Plug-in hybrid vehicles can be driven
using electricity charged from an exter- nal power source. However, as the gas-oline engine is used depending on the
situation ( P.90) even if in EV mode or AUTO EV/HV mode, and the gasoline engine is provided on board as a power
source for driving in HV mode, it is needed to refueling the vehicle.
Check the fuel amount and refill immedi-
ately when the fuel level becomes low. ( P.342)
■If the vehicle is not used for a long time
●The 12-volt battery may discharge. In
this event, charge the 12-volt battery. ( P.606) In order to prevent the hybrid battery
(traction battery) from becoming
extremely low in charge, charge the hybrid battery (traction battery) from external power source or start the
hybrid system at least once every 2 or 3 months, and turn the power switch off after the gasoline engine has
stopped automatically. (If the gasoline engine does not start up even after approximately 10 seconds have
passed since the “READY” indicator came on, the power switch can be turned to off without any further
action.) When the 12-volt battery is dis-charged, refer to “If the 12-volt battery
is discharged” ( P.606) and perform the correction procedure.
●When the vehicle is left with the AC charging cable connected, the elec-tricity consumption amount of the 12-
volt battery increases due to controls, such as the system checking, operat-ing. When the AC charging cable is
not needed, immediately remove it from the vehicle.
When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of the
vehicle’s approach. The sound will
stop when the vehicle speed
exceeds approximately 25 km/h (15
mph).
■Acoustic Vehicle Alerting System
In the following cases, the Acoustic
Vehicle Alerting System may be difficult for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Acoustic Vehicle Alerting
System

1002-1. Plug-in hybrid system
Shift the shift lever to D when
stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift
lever to P when parking. When
using the N, there is no positive
effect on fuel consumption. In the
N, the gasoline engine operates but
electricity cannot be generated.
Also, when using the air condition-
ing system, etc., the hybrid battery
(traction battery) power is con-
sumed.
Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accelera-
tion 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 (traction
battery) power, resulting in poor
fuel consumption. Battery power
can be restored by driving with
the accelerator pedal slightly
released.
Make sure to operate the brakes
gently and a timely manner. A greater amount of electrical energy
can be regenerated when slowing
down.
Repeated acceleration and decel-
eration, as well as long waits at traf-
fic lights, will lead to high fuel and
electricity consumption. Check traf-
fic reports before leaving and avoid
delays as much as possible. When
driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly
while avoiding overuse of the accel-
erator pedal. Doing so can help
control excessive electricity and
fuel consumption.
Control and maintain the vehicle
at a constant speed. Before stop-
ping at a toll booth or similar,
allow plenty of time to release
the accelerator and gently apply
the brakes. A greater amount of
electrical energy can be regener-
ated when slowing down.
Electricity consumption will
increase significantly when driv-
ing at high speeds in EV mode or
AUTO EV/HV mode. If there will
be a long distance to the next
external charging point after
leaving a freeway, it is recom-
mended to drive in HV mode

to EV mode or AUTO EV/HV
mode after leaving the freeway.
(P.86)
Turn the “A/C” switch off when it
is not needed. Doing so can help
reduce excessive electricity and
fuel consumption.
In summer: When the ambient tem-
perature is high, use the recirculated air
mode. Doing so will help to reduce the
burden on the air conditioning system
and reduce electricity and fuel con-
sumption as well.
In winter: Avoid excessive and unnec-
essary use of the heater. Usage of the
heated steering wheel (if equipped)
(P.462) and seat heaters (P.463)
are effective.
Using the Remote Air Condition-
ing System (P.460) while the
AC charging cable is connected
to the vehicle can reduce elec-
tricity consumption immediately
after starting off by operating air
conditioning mainly using elec-
tricity from an external power
source.
When setting the charging
schedule, setting the charging
mode to “Departure” and “Cli-
mate Prep” to on can reduce
electricity consumption immedi-
ately after starting off by operat-
ing air conditioning before
charging is completed. (P.144)Make sure to check the tire inflation
pressure frequently. If there is
improper tire inflation pressure in
the tires, the EV driving range will
become shorter, and fuel consump-
tion when in HV mode will increase.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to increased fuel
and electricity consumption.
Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a
large roof rack will also cause poor
fuel economy.
Since the gasoline engine starts up
and cuts out automatically, warm-
ing up is not necessary.

■When starting off, depress the
accelerator pedal smoothly to
accelerate
As a guide, accelerate up to
approximately 20 km/h (12mph) in
the first 5 seconds.
Electrical and fuel efficiency can be
improved just by using the ECO
Accelerator Guidance displayed on
the multi-information display and
taking care to start off gently.
(P.182)
When the driving mode is set to Eco
drive mode, depressing the accelerator
pedal generates smooth torque that
makes it easier to operate the accelera-
tor gently.
■Maintain sufficient vehicle-to-
vehicle distance and do not
accelerate or decelerate
unnecessarily
Try to maintain a fixed speed while
driving. Driving at a short vehicle-
to-vehicle distance will result in
repeating wasteful acceleration and
deceleration, which will worsen the
electrical and fuel efficiency.
■Release the accelerator pedal
early before stopping the vehi-
cle, such as at a traffic light
The regenerative brake will operate
to convert the kinetic energy of the
vehicle into electrical energy, which
will charge the hybrid battery (trac-
tion battery).
The regeneration status can be
checked from the Hybrid System
Indicator. (P.177)When the brake pedal is depressed
lightly during deceleration, the
regeneration amount increases,
enabling more electrical energy to
be recovered.
If the brake pedal is depressed too
strongly, the recovered amount indica-
tor will reach the maximum level and
the upper limit of the recoverable
energy will be exceeded. Therefore, be
sure to operate the brake pedal early.
■Use the air conditioning sys-
tem appropriately, and also
utilize the heated steering
wheel (if equipped) and seat
heaters
In EV mode, the vehicle is cooled
and heated by electrical energy.
(Except in extremely cold tempera-
tures of approximately -10°C (14°F)
or less.)
Preventing excessive cooling or
heating of the vehicle will reduce
power consumption and improve
electrical efficiency.
The heated steering wheel (if
equipped) and seat heaters are effi-
cient heating device that directly
warm the body using less electric
power.
When used together with the air condi-
tioning system, a low temperature set-
ting can be used to improve electrical
and fuel efficiency.
■Check the tire pressure
If the tire pressure is lower than the
specified value, it will worsen the
electrical and fuel efficiency.

1042-1. Plug-in hybrid system
A pressure level 50 kPa (0.5 kgf/cm
2 or
bar, 7 psi) lower than the specified
value will cause a worsening of several
percentage points.
■When driving on highways,
use the EV/HV mode selection
switch to drive in HV mode
The power consumption will
increase significantly if the vehicle
is driven in EV mode on highways.
■Do not load unnecessary
objects in the vehicle
Driving with objects weighing 100
kg (220 lb.) in the vehicle will
worsen the electrical and fuel effi-
ciency by approximately 3%.
Air resistance also greatly affects
electrical and fuel efficiency.
Remove any exterior accessories
such as a roof luggage carrier when
they are not being used.
The running resistance of snow
tires is high and they will worsen
electrical and fuel efficiency.
Replace them with standard tires
as soon as they are no longer
needed.
■Know your vehicle’s electrical
and fuel efficiency
If you know your vehicle’s daily
electrical and fuel efficiency, you
will understand the benefits of Eco
drive.
Use the Power Consumption/Fuel
Economy, ECO Accelerator Guid-
ance/“Eco Score” and other data
displayed on the multi-information display.
The following indicate that charging
has been carried out properly.
The charging indicator of the
charging port turns off
“Charging Complete” is dis-
played on the multi-information
display when a door is opened
with the power switch off
(P.131)
Regardless of the type of power
source or whether the charging
schedule function is used, charging
is completed if the above can be
confirmed.
