Replacing battery
The installed battery is specific to the Stop & Start system. It should only be
replaced with a battery of identical type and rating.
Ask any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional for further details.
CAUTION
When the Stop & Start system is operating
Keep the shift lever in N and apply the brake pedal or parking brake for
safety while the engine is stopped due to the Stop & Start system (while
the Stop & Start indicator is on).
Unexpected accidents may occur due to the automatic engine start func-
tion.
Do not leave the vehicle while the engine is stopped due to the Stop &
Start system (while the Stop & Start indicator is on).
Unexpected accidents may occur due to the automatic engine start func-
tion.
Ensure that the engine is not stopped by the Stop & Start system while the
vehicle is in a poorly ventilated area. The engine may restart due to the
automatic engine start function, causing exhaust gases to collect and
enter the vehicle and resulting in death or a serious health hazard.

2-5. Driving information
YARIS_F (including HV)_WE_52C79E
Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
Pre-winter preparations
Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
• Power control unit coolant (hybrid vehicle)
Except hybrid vehicle: Have a service technician inspect the
condition of the battery.
Hybrid vehicle: Have a service technician inspect the condi-
tion of the 12-volt battery.
Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front tires.
Ensure that all tires are the same size and brand, and that their wear
level is not noticeably different with each other. Also make sure that
chains match the size of the tires.
Before driving the vehicle
Perform the following according to the driving conditions:
Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.

YARIS_F (including HV)_WE_52C79E
Air conditioning odors
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.
An odor comes from the air conditioning system due to the Stop &
Start system operation (vehicles with a Stop & Start system)
When the engine is stopped due to the Stop & Start system, an odor caused
by moisture may be detected. This does not indicate a malfunction.
Air conditioning filter
P. 502
CAUTION
To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
NOTICE
To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.

YARIS_F (including HV)_WE_52C79E
EON (Enhanced Other Network) system (for traffic announcement
function)
If the RDS station (with EON data) you are listening to is not broadcasting a
traffic information program and the audio system is in the TA (traffic
announcement) mode, the radio will be switched automatically to a station
broadcasting a traffic information program in the EON AF list when traffic
information begins.
When the battery (except hybrid vehicle) or 12-volt battery (hybrid
vehicle) is disconnected
Stations presets are erased.
Reception sensitivity
Maintaining perfect radio reception at all times is difficult due to the con-
tinually changing position of the antenna, differences in signal strength
and surrounding objects, such as trains, transmitters, etc.
The radio antenna is mounted on the rear roof. The antenna can be
removed from the base by turning it.
Digital Audio Broadcast (DAB) radio
The optional radio antenna and tuner are necessary for the use of Digital
Audio Broadcast (DAB) radio.
NOTICE
To prevent damage, remove the antenna in the following cases.
The antenna will touch the ceiling of a garage.
A cover will be put on the roof.
