Maintenance requirements
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
For full details of your maintenance schedule, refer to the “Toyota Service
Booklet” or “Toyota Warranty Booklet”.
What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself if you have a little
mechanical ability and a few basic automotive tools.
Note, however, that some maintenance tasks require special tools and
skills. These are best performed by qualified technicians. Even if you are
an experienced do-it-yourself mechanic, we recommend that repairs and
maintenance be conducted by any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional. Any authorized Toyota
dealer or repairer will keep a record of maintenance, which could be useful
should you ever require Warranty Service. Should you choose to select a
qualified and equipped professional other than an authorized Toyota
repairer to service or maintain your vehicle, we recommend that you
request that a record of maintenance be kept.
To ensure safe and economical driving, day-to-day care and reg-
ular maintenance are essential. Toyota recommends the follow-
ing maintenance:

■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 dealers or repairers or ot her duly qualified and equipped profession-
als. For repairs and services covered by your warranty, please visit an autho-
rized Toyota dealer or repairer, who will use genuine Toyota parts in repairing
any difficulties you may encounter. There can also be advantages in utilizing
authorized Toyota dealers 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 dealer or repairer, or another duly qualified and equipped profes-
sional will perform all of the scheduled maintenance on your vehicle reliably
and economically 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, 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
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.

Maintenance and care
YARIS_HV_OM_Europe_OM52G76E
NOTICE
■To avoid damage to the tire pressure warning valves and transmitters
(vehicles with a tire pressure warning system)
When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant is used, contact
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional or other qualified service shop as soon as possible.
After use of liquid sealant, make sure to replace the tire pressure warning
valve and transmitter when repairing or replacing the tire. ( P. 350)
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
■ Low profile tires (vehicles with 195/50R16 tires)
Low profile tires may cause greater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay attention to
the following:
● Be sure to use proper tire inflation pressure. If tires are under-inflated, they
may be damaged more severely.
● Avoid potholes, uneven pavement, curbs and other road hazards. Failure
to do so may lead to severe tire and wheel damage.
■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

WARNING
■Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an
accident.
NOTICE
■ Replacing tire pressure warning valves and transmitters (vehicles with
a tire pressure warning system)
● Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
● Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with
non-genuine wheels.

A buzzer will sound if the vehicle reaches a speed of 5 km/h (3 mph) or
more with any door open.
*4: Driver’s and passenger’s seat belt buzzer:
The driver’s and passenger’s seat belt buzzer sounds to alert the driver
and passenger that his or her seat belt is not fastened. The buzzer sounds
for 30 seconds after the vehicle reaches a speed of at least 20 km/h
(12 mph). Then, if the seat belt is still unfastened, the buzzer will sound in
a different tone for 90 more seconds.
Carrying out the corresponding action turns the warning light off.
■ Passenger detection sensor and passenger seat belt reminder
● If luggage is placed on a passenger seat, the passenger detection sensor
may cause the warning light to flash even if a passenger is not sitting in the
seat.
● If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning light may not operate properly.
■ If the malfunction indicator lamp comes on while driving
For some models, the malfunction indicator lamp will come on if the fuel tank
becomes completely empty. If the fuel tank is empty, refuel the vehicle imme-
diately. The malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized Toy-
ota dealer or repairer, or another duly qualified and equipped professional as
soon as possible.
