For safety and security
There is an air intake vent under
the right side of the rear seat for
the purpose of cooling the
hybrid battery (traction battery).
If the vent is blocked,
charging/discharging of the
hybrid battery (traction battery)
may become limited.
WARNING
●Never resell, hand over or mod-
ify the hybrid battery. To prevent
accidents, hybrid batteries that
have been removed from a dis-
posed vehicle are collected
through Toyota dealer. Do not
dispose of the battery yourself.
Unless the battery is properly col-
lected, the follo wing may occur,
resulting in dea th or serious
injury:
• The hybrid battery may be ille- gally disposed of or dumped,
and it is hazardous to the envi-
ronment or someone may touch
a high voltage part, resulting in
an electric shock.
• The hybrid battery is intended to be used exclusively with your
hybrid vehicle. If the hybrid bat-
tery is used outside of your
vehicle or modifi ed in any way,
accidents such as electric
shock, heat generation, smoke
generation, an explosion and
electrolyte leakage may occur.
When reselling or handing over
your vehicle, the possibility of an
accident is extremely high
because the person receiving the
vehicle may not be aware of these
dangers.
●If your vehicle is disposed of
without the hybrid battery hav-
ing been removed, there is a
danger of serious electric shock
if high voltage parts, cables and
their connectors are touched. In
the event that your vehicle must
be disposed of, the hybrid bat-
tery must be disposed of by
your Toyota dealer or a qualified
service shop. If the hybrid bat-
tery is not dispos ed of properly,
it may cause electric shock that
can result in death or serious
injury.

■Hybrid battery (traction bat-
tery) air intake vent
●Make sure not to block the air
intake vent with anything, such
as a seat cover, plastic cover, or
luggage. If the vent is blocked,
the charging/discharging of the
hybrid battery (traction battery)
may become limited.
●When dust etc. has accumu-
lated in the air intake vent, clean
it with a vacuum cleaner to pre-
vent the vent from clogging.
●Clean the air intake vent regu-
larly to prevent the charging/dis-
charging of the hybrid battery
(traction battery) from being
restricted.

801-4. Hybrid system
When a certain level of impact is
detected by the impact sensor,
the emergency shut off system
blocks the high voltage current
and stops the fuel pump to mini-
mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates,
your vehicle will not restart. To
restart the hybrid system, con-tact your Toyota dealer.

3664-5. Using the driving support systems
1Eco drive mode
Suitable for driving to improve fuel
economy by more smoothly gener-
ating torque in response to acceler-
ator pedal operations compared to
normal mode and restraining air
conditioning system operations
(heating/cooling).
When the switch is turned to the left
while not in Eco drive mode, the
system switches to Eco drive mode
and the Eco drive mode indicator
illuminates on the mu lti-information
display.
2 Normal mode
Suitable for n ormal driving.
The driving mode returns to normal
mode if the switch i s pressed while
in Eco drive mode or sport mode.
3 Sport mode
Controls the steering feeling and
hybrid system to create an acceler-
ation response tha t is suitable for
sporty driving. Suitable for when
crisp handling is desired, such as
when driving on mountainous
roads.
When the switch is turned to the
right while not in sport mode, the
system switches to sport mode and
the sport mode indicator illuminates
on the multi-information display.
■When changing to a driving
mode other than normal mode
●The background color of the multi-
information display changes
according to the selected driving
mode.
●When the speedometer is set to
analog display, the speedometer
display color also changes. (For
vehicles with the 7-inch multi-
information di splay only)
●The color of the switch changes
according to the selected driving
mode. (For vehicles with the 7-
inch multi-information display
only)
■Air conditioning system opera-
tion in Eco drive mode
In Eco drive mode, heating/cooling
operations and the fan speed is con-
trolled to improve fuel efficiency.
Perform the following procedures to
increase the air conditioning perfor-
mance.
●Turn eco air conditioning mode off
(  P.525)
●Adjust the fan speed ( P.525)
●Cancel Eco drive mode

3764-6. Driving tips
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.366)
The Eco-friendly driving is pos-
sible by keeping the indicator of
Hybrid System Indicator within
Eco area. ( P.95, 100)
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 position,
there is no positive effect on fuel
consumption. In the N position,
the gasoline engine operates
but electricity cannot be gener-
ated. Also, when using the air conditioning system, etc., the
hybrid battery (traction battery)
power is consumed.

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.

odors
●To let fresh air in, set the air condi-
tioning system to the outside air
mode.
●During use, various odors from
inside and outside the vehicle may
enter into and a ccumulate in the
air conditioning system. This may
then cause odor to be emitted
from the vents.
●To reduce potential odors from
occurring:
• It is recommended that the air conditioning system be set to out-
side air mode prior to turning the
vehicle off.
• The start timing of the blower may
be delayed for a short period of
time immediately after the air con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.
