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.

*:
The weight borne by the rear axle should not exceed the maximum
permissible rear axle capacity. Exceeding this weight is dangerous.
The values for towing capacity were derived from testing conducted
at sea level. Take note that engine output and towing capacity will be
reduced at high altitudes.
*: To distinguish the vehicle category, ask any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
CAUTION
When the gross vehicle mass limit or maximum permissible axle
capacity is exceeded (vehicle category M1 models*)
Do not exceed the established speed limit for towing a trailer in built-up

YARIS_F (including HV)_WE_52C79ETransmission information
Vehicles with a Multidrive and multi-mode manual transmission:
To maintain engine braking efficiency, when using engine braking,
do not use the transmission in D. Transmission shift gear position
must be in 4 in the M mode. (P. 255, 260)
Vehicles with a manual transmission:
To maintain engine braking efficiency, when using engine braking,
do not use the transmission in 5 and 6 (vehicles with a 6-speed
manual transmission) gear. (P. 265)
If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures
exceeding 30C (85F) may result in the engine overheating. If the
high engine coolant temperature warning light flashes or comes
on, turn the air conditioning off immediately, leave the road and
stop the vehicle in a safe place. (P. 635)
When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle
and trailer. Firmly set the parking brake and shift the shift lever to P
for Multidrives, E, M or R for multi-mode manual transmissions,
and 1 or R for manual transmissions.

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.
