When driving
YARIS_F (including HV)_WE_52C79E
The hybrid battery (traction battery) is low.
• When the low traction battery indicator light came on.
• When the amount of remaining hybrid battery (traction battery) charge
displayed on the “touch screen” is low. (P. 58)
Vehicle speed is high.
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
The windshield defogger is in use.
Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically
restart in the following situations. When EV drive mode is canceled, a buzzer
will sound and the EV drive mode indicator will flash and go off.
The hybrid battery (traction battery) becomes low. (P. 58, 568)
Vehicle speed becomes high.
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
Possible driving distance when driving in EV drive mode
In EV drive mode, it is possible to drive up to about 2 km (1.3 miles) if driving
at a speed of about 45 km/h (28 mph) or less.
(The distance that is possible depends on the hybrid battery [traction battery]
level and driving conditions.)
Fuel economy
Your vehicle is designed to achieve the best possible fuel economy during
normal driving (using the gasoline engine and electric motor [traction
motor]). Driving in EV drive mode more than necessary may lower fuel econ-
omy.
CAUTION
Caution while driving
When driving in EV drive mode, pay special attention to the area around the
vehicle. Because there is no engine noise, pedestrians, people riding bicy-
cles or other people and vehicles in the area may not be aware of the vehicle
starting off or approaching them, so take extra care while driving.

YARIS_F (including HV)_WE_52C79E
Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. (P. 368) To improve air
conditioning performance, adjust the temperature setting or fan speed, or
turn off Eco drive mode.
When in heavy traffic
If the shift lever is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid putting the shift
lever in N for an extended period of time.
If the shift lever cannot be shifted from P
P. 616
CAUTION
When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.

The meters and display operate when
Except hybrid vehicle
Vehicles without a smart entry & start system:
The engine switch is in the “ON” position.
Vehicles with a smart entry & start system:
The “ENGINE START STOP” switch is in IGNITION ON mode.
Hybrid vehicle
Vehicles without an electronic key:
The engine switch is in the “ON” position.
Vehicles with an electronic key:
The “POWER” switch is in ON mode.
Hybrid System Indicator
By keeping the indicator needle within Eco area, more Eco-friendly driv-
ing can be achieved.
Charge area indicates regeneration
* status. Regenerated energy will be
used to charge the battery.
*: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical energy.
Power area
Shows that the driving power is more
than the upper limit of Eco driving.
Eco area
Shows that the vehicle is driven Eco-
friendly.
Hybrid Eco area
Shows that the vehicle is driven in a
condition that promotes frequent
motor-only operation. (When the vehi-
cle is operating with low driving load,
such as when driving slowly, using
Hybrid Eco area leads Eco-friendly
driving.)
Charge area
Shows regenerative charging.

EV indicator customization (hybrid vehicle)
EV indicator can be activated or deactivated by
pressing the display change button when the EV
indicator customization display is displayed.
To change the EV indicator customization display,
display the odometer and press and hold the display
change button until the display changes.
When disconnecting and reconnecting battery (except hybrid vehicle)
or 12-volt battery (hybrid vehicle) terminals
The following information data will be reset:
Stop & Start system total operation time (if equipped)
Average fuel consumption
Driving range
Average vehicle speed
NOTICE
The multi-information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.

cle without a smart entry & start system) or the “ENGINE START STOP”
switch is in off (vehicle with a smart entry & start system).

YARIS_F (including HV)_WE_52C79EIf the Stop & Start cancel switch is pressed while the vehicle is
stopped
When the engine is stopped by the Stop & Start system, press-
ing the Stop & Start cancel switch will restart the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned off), the engine will not be stopped.
With the Stop & Start system disabled, pressing the Stop & Start
cancel switch will re-enable the system but not stop the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned on), the engine will be stopped.
Operating conditions
The Stop & Start system is operational when all of the following condi-
tions are met:
• The engine is adequately warmed up.
• The battery is sufficiently charged.
• The driver’s door is closed.
• Vehicles with a Multidrive: The driver’s seat belt is fastened.
• The hood is closed.
• The accelerator pedal is not being depressed.
• The shift lever is not in R.
In the following circumstances the engine may not be stopped by the
Stop & Start system. This is not a malfunction of the Stop & Start system.
• Engine coolant temperature or transmission fluid temperature is too
low or too high.
• The air conditioning system is being used when the vehicle interior
temperature is extremely high such as after the vehicle was parked
under the hot sun.
• Vehicles with an automatic air conditioning system only: The wind-
shield defogger is being used.
• The battery is not sufficiently charged, or is undergoing a periodic
recharge.
• Due to traffic or other circumstances the vehicle is stopped repeatedly,
resulting in the amount of time the engine is stopped by the Stop &
Start system to become excessively high.
• The brake pedal is not depressed firmly.
