WARNING
■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 engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
■ Using the tire chains
Use only chains that are of the correct size for your tires so as not to dam-
age the vehicle body or suspension.

2265-1. Using the air conditioning system and defogger
YARIS_GRMN_OM_Europe_OM52J40E
WARNING
■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
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
Do not touch the outside surface of the rear view mirrors, as they can
become very hot and burn you.
NOTICE
■ To prevent battery discharge
Do not leave the air conditioning syst em on longer than necessary when the
engine is stopped.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.

WARNING
■When cleaning the windshield
● When the upper part of the windshield where the raindrop sensor is
located is touched by hand

■ When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components, etc., to catch fire.
■ Precautions regarding the exhaust pipes
Exhaust gases cause the exhaust pipes to become quite hot.
When washing the vehicle, be careful not to touch the pipes until they have
cooled sufficiently, as touching hot exhaust pipes can cause burns.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wiper
may operate unexpectedly in the follow-
ing situations, and may result in hands
being caught or other serious injuries and

Maintenance and care
■Where to go for the maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that all repairs and service operations be carried out by authorized
Toyota retailers or Toyota authorized repairers, or any reliable repairers. For
repairs and services covered by your warranty, please visit an authorized
Toyota retailer or repairer, who will use genuine Toyota parts in repairing any
difficulties you may encounter. There can also be advantages in utilizing
authorized Toyota retailers or repairers for non-warranty repairs and services,
as members of the Toyota network will be able to expertly assist you with any
difficulties you may encounter.
Your Toyota retailer or Toyota authoriz ed repairer, or any reliable repairer will
perform all of the scheduled maintenance on your vehicle reliably and eco-
nomically due to their experience with Toyota vehicles.
■ Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
● Engine misfire, stumbling or pinging
● Appreciable loss of power
● Strange engine noises
● A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
● Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)
● Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
● Vehicle pulls to one side when driven straight on a level road
● Strange noises related to suspension movement
● Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal,
pedal almost touches the floor, vehicle pulls to one side when braking
● Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as pos-
sible. Your vehicle may need adjustment or repair.
