For safety and security
UK_AURIS/AURIS_HV_EE (OM12G88E)After the 12-volt battery has discharged or has been changed or
removed
The gasoline engine may not stop even if the vehicle is running on the hybrid
battery (traction battery). If this continues for a few days, contact any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. For safety, apply the parking brake and make sure to shift the shift
position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction:
Motor sounds may be heard from the engine compartment.
Sounds may be heard from the hybrid battery (traction battery) under the
rear seats when the hybrid system starts or stops.
Sounds from the hybrid system may be heard when the back door is open.
Sounds may be heard from the hybrid transmission when the gasoline
engine starts or stops, when driving at low speeds, or during idling.
Engine sounds may be heard when accelerating sharply.
Sounds may be heard due to regenerative braking when the brake pedal is
depressed.
Vibration may be felt when the gasoline engine starts or stops.
Cooling fan sounds may be heard from the air intake vents on the side of the
lower part of the rear left seats.
Maintenance, repair, recycling, and disposal
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.
Customization
Settings (e.g. on/off operation of the EV indicator) can be changed.

For safety and security

There is an air intake vent on the
side of the lower part of the rear
left seat for the purpose of cooling
the hybrid battery (traction bat-
tery). If the vent becomes
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel leak-
age. If the emergency shut off system activates, your vehicle will not
restart. To restart the hybrid system, contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
A message is automatically displayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. (P. 631)

NOTICE
Hybrid battery air vent
Do not put foreign objects over or in front of the air vent. The hybrid battery
(traction battery) may overheat and be damaged.
Clean the air vent regularly to prevent the hybrid battery (traction battery)
from overheating.
Do not wet or allow foreign substances to enter the air vent as this may
cause a short circuit and damage the hybrid battery (traction battery).
Do not put in foreign objects into the air vent. The cooling blower may be
damaged.
Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.

4-6. Driving tips
Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/cooling) will be minimized, improving
the fuel economy. (P. 306)
Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. (P. 138)
When braking the vehicle
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel consumption. Check traffic reports
before leaving and avoid delays as much as possible. When
encountering a delay, gently release the brake pedal to allow the
vehicle to move forward slightly while avoiding overuse of the
accelerator pedal. Doing so can help control excessive gasoline
consumption.
Highway driving
Control your speed and keep at a constant speed. Also, before
stopping at a toll booth or similar, allow plenty of time to release the
accelerator and gently apply the brakes. A greater amount of elec-
trical energy can be retained when slowing down.
Hybrid vehicle driving tips (hybrid model)
For economical and ecological driving, pay attention to the fol-
lowing points:

Interior features
Operation of the air conditioning system in Eco drive mode (hybrid
model)
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
Engine speed and compressor operation controlled to restrict heating/cool-
ing capacity
Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
Adjust the fan speed
Turn off Eco drive mode
Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
Fogging up of the windows
The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
If you turn off, the windows may fog up more easily.
The windows may fog up if the recirculated air mode is used.
Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to the recirculated air mode. This is effec-
tive in preventing outside air from entering the vehicle interior. During
cooling operation, setting the recirculated air mode will also cool the vehicle
interior effectively.
Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
When the outside temperature is low
The dehumidification function may not operate even when is pressed.

4045-1. Using the air conditioning system and defogger
UK_AURIS/AURIS_HV_EE (OM12G88E)When
is selected for the air outlets used
For your driving comfort, air flowing to the feet may be warmer than air flow-
ing to the upper body depending on the position of the temperature adjust-
ment dial.
Ventilation and air conditioning odors
To let fresh air in, set the air conditioning system to the outside air mode.
During use, various odors from inside and outside the vehicle may enter into
and accumulate 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 outside 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 conditioning system is started in automatic mode.
Air conditioning system operations when the engine is stopped due to
the Stop & Start system (vehicles with a Stop & Start system)
When the engine is stopped due to Stop & Start system operation, the air
conditioning cooling, heating and dehumidification functions turn off and only
ambient temperature air is blown, and there is a possibility that the blowing of
ambient temperature air will stop. To prevent the air conditioning system from
turning off, press the Stop & Start cancel switch to deactivate the system.
When the windshield is fogged up and the engine is stopped due to the
Stop & Start system (vehicles with a Stop & Start system)
Press the Stop & Start cancel switch to restart the engine and turn on
to defog the windshield. Simply pressing will restart the engine and
defog the windshield.
If the windshield continuously fogs up, press the Stop & Start cancel switch
and refrain from using the Stop & Start system.
When an odor comes from the air conditioning system while the engine
is stopped due to the Stop & Start system (vehicles with a Stop & Start
system)
Press the Stop & Start cancel switch to restart the engine.
