EV drive mode
Turns EV drive mode on/off
When EV drive mode is turned on,
the EV drive mode indicator will
come on. Pressing the switch
when in EV drive mode will return
the vehicle to normal driving (using
the gasoline engine and electric
motor [traction motor]).
■ Situations in which EV drive mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situations. If it
cannot be turned on, a buzzer will sound.
● 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.
● The temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 0°C (32°F) for a
long period of time etc.
● The gasoline engine is warming up.
● The hybrid battery (traction battery) is low.
• In the instrument cluster, the low traction battery warning light comes on.
( P. 399)
• The remaining battery level indicated in the energy monitor display is low.
( P. 104)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
● The windshield defogger is in use.
In EV drive mode, electric power is supplied by the hybrid bat-
tery (traction battery), and only the electric motor (traction
motor) is used to drive the vehicle.
This mode allows you to drive in residential areas early in the
morning and late at night, or in indoor parking lots etc. without
concern for noises and gas emissions.

YARIS_HV_EE_OM52G10E
■Daytime running light system
To make your vehicle more visible to other drivers during daytime driving, the
daytime running lights turn on automatically whenever the hybrid system is
operated and the parking brake is released with the headlight switch off or in
the “AUTO” position. (Illuminate bright er than the front position lights.) Day-
time running lights are not designed for use at night.
■ Headlight control sensor (if equipped)
■ Automatic light off system (if equipped)
Vehicles without a smart entry & start system
● When the light switch is in or : The headlights and front fog
lights turn off automatically when the power switch is turned to the “LOCK”
position.
● When the light switch is in : The headlights and all the lights turn off
automatically when the power switch is turned to the “LOCK” position.
To turn the lights on again, turn the power switch to the “ON” position, or turn

■ Automatic High Beam (if equipped)
P. 229
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

NOTICE
■Front sensor
Observe the following to ensure that the sensor operates correctly:
● Do not attach window tinting to the windshield.
● On cold days when there is a large temperature difference between the
vehicle interior and outside air temperatures, the windshield fogs up easily.
If the part of the windshield in front of the front sensor becomes fogged up
or covered with condensation or ice, the system temporarily stops working
and the PCS warning light flashes. In that case, use the front defroster to
remove the fog, condensation, or ice. ( P. 288)
● Keep the windshield clean at all times. Also, even when using a glass
coating agent, if water droplets and so forth form on the windshield, use
the wipers to remove them.
The pre-crash safety system may not function properly if the windshield is
dirty or covered with an oily film, water droplets, snow, etc.
If the inner side of the windshield where the front sensor is installed is dirty,
do not attempt to remove the front sensor. Contact any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional.
●Do not attach objects, such as stickers,
transparent stickers, etc., and so forth,
to the outer side of the windshield in
front of the front sensor (shaded area in
the illustration) or use a glass coating
agent.
A: From the top of the windshield to
approximately 10 cm (4.0 in.) below
the bottom of the front sensor
B: Approximately 20 cm (7.9 in.)
(Approximately 10 cm (4.0 in.) to the
right and left from the center of the
front sensor)
● Do not install or attach anything to the
inner side of the windshield under the
front sensor (shaded area in the illustra-
tion).
A: Approximately 10 cm (4.0 in.) (Start-
ing from the bottom of the front sen-
sor)
B: Approximately 20 cm (7.9 in.)
(Approximately 10 cm (4.0 in.) to the
right and left from the center of the
front sensor)

■ Conditions under which the system may operate even if there is no pos-
sibility of a collision
In the following situations the sensor may detect an object and cause the sys-
tem to determine that there is a possibility of a frontal collision and operate.
When there is an object (traffic sign, guard rail, etc.) by the roadside at
the entrance of a curve
When passing an oncoming vehicle on a curve
When passing an oncoming vehicle while making a left or right turn
When rapidly closing on a preceding vehicle
When rapidly closing on an electric toll gate barrier, parking area barrier,
or other barrier that opens and closes
When approaching an overpass, traffic sign, billboard, etc.
When the front part of the vehicle is raised or lowered
When the sensor is misaligned due to a strong impact being applied to
the sensor, etc.
When there is a structural object (billboard, street light, etc.) at the top of
an uphill road
When there is a metal object (manhole cover, steel plate, etc.) at the bot-
tom of a downhill road
When approaching a low hanging object that may contact the vehicle,

face
When the vehicle is being parked in a place where there is a low hanging
object at the height of the front sensor
When passing extremely close to an object (stopped vehicle, guardrail,
etc.)
■ Situations in which the pre-crash safety system may not function prop-
erly
