When driving
YARIS_F (including HV)_WE_52D27E
CAUTION
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
When the TRC/VSC systems are turned off (except hybrid vehicle)
Be especially careful and drive at a speed appropriate to the road condi-
tions. Do not turn the TRC/VSC systems off unless necessary, as these are
the systems to ensure vehicle stability and driving force by automatically
controlling braking and engine outputs.
Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further information when replacing tires or
wheels.
Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

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.

Selecting tire chains
Use the correct tire chain size when mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
Except 175/65R14 tires: 3 mm
(0.12 in.) in diameter
175/65R14 tires: 4 mm (0.16
in.) in diameter
Cross chain
Except 175/65R14 tires: 4 mm
(0.16 in.) in diameter
175/65R14 tires: 5 mm (0.20
in.) in diameter
Regulations on the use of tire chains
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before installing
chains.
Tire chain installation
Observe the following precautions when installing and removing chains:
Install and remove tire chains in a safe location.
Install tire chains on the front tires only. Do not install tire chains on the
rear tires.
Install tire chains on front tires as tightly as possible. Retighten chains
after driving 0.5 1.0 km (1/4 1/2 mile).
Install tire chains following the instructions provided with the tire chains.
If wheel ornaments are used, they will be scratched by the chain band,
so remove the ornaments before putting on the chains. (P. 581)

CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
Use tires of the specified size.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
Use snow tires on all, not just some wheels.
Do not use tires of noticeably different wear level.
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden to engine braking.
Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

Maintenance and care
YARIS_F (including HV)_WE_52D27E
When to replace your vehicle’s tires
Tires should be replaced if:
You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage
A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
Tire life
Any tire over 6 years old must be checked by a qualified technician even if it
has seldom or never been used or damage is not obvious.
Low profile tires (vehicles with 195/50R16 tires)
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.
If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
Vehicles with a spare tire of the same wheel type as the
installed tires
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that tire rotation is car-
ried out approximately every
10000 km (6000 miles).

YARIS_F (including HV)_WE_52D27E
CAUTION
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as dan-
gerous handling characteristics, which may lead to an accident resulting in
death or serious injury.
Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
Do not use tire sizes other than those recommended by Toyota.
Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
Do not mix summer, all season and snow tires.
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.

Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause a loss of
handling control.
Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width and inset*.
Replacement wheels are available at any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
Wheels of different sizes or types
Used wheels
Bent wheels that have been straightened
Aluminum wheel precautions (if equipped)
Use only Toyota wheel nuts and wrenches designed for use
with your aluminum wheels.
When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1600 km (1000 miles).
Be careful not to damage the aluminum wheels when using
tire chains.
Use only Toyota genuine balance weights or equivalent and
use a plastic or rubber hammer when balancing your wheels.
