YARIS_F (including HV)_WE_52D27E
Checking interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to
the “Toyota Service Booklet” or “Toyota Warranty Booklet”.)
If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
When using the air conditioning system
Make sure that a filter is always installed.
Using the air conditioning system without a filter may cause damage to the
system.
Remove the air conditioning
filter and replace it with a new
one.
The“UP” marks shown on the
filter should be pointing up.

The driver’s and passengers seat belt buzzer sounds to alert the driver and
passengers that their seat belt is not fastened. The buzzer sounds for 30
seconds after the vehicle has reached 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.

reminder light is on. In this event, have the vehicle inspected by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.

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 passen-
ger, and the warning light may not operate properly.
Electric power steering warning light (warning buzzer)
Except hybrid vehicle: When the battery charge becomes insufficient or the
voltage temporarily drops, the electric power steering system warning light
may come on and the warning buzzer may sound.
Hybrid vehicle: When the 12-volt battery charge becomes insufficient or the
voltage temporarily drops, the electric power steering system warning light
may come on and the warning buzzer may sound.
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
immediately. The malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional as soon as possible.
If the engine oil change reminder light flashes (diesel engine with a
DPF system)
Repeated short trips and/or low-speed driving may cause the oil to degrade
sooner than usual, regardless of the actual distance driven. If this happens,
the engine oil change reminder light will flash.
Engine oil change reminder light comes on (diesel engine only)
Vehicles without a DPF system:
Replace the engine oil and oil filter when the engine oil change reminder
light does not come on even if you have driven over 40000 km (25000 miles)
after the engine oil was changed.
There is a possibility that the engine oil change reminder light has been illu-
minated when you have driven less than 40000 km (25000 miles) based on
a usage or driving condition.

577 5-2. Steps to take in an emergency
When trouble arises
YARIS_F (including HV)_WE_52D27E
Vehicles with a DPF system:
Replace the engine oil and oil filter when the engine oil change reminder
light does not come on even if you have driven over 15000 km (9300 miles)
after the engine oil was changed.
There is a possibility that the engine oil change reminder light has been illu-
minated when you have driven less than 15000 km (9300 miles) based on a
usage or driving condition.
CAUTION
When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
When driving to clean the DPF catalytic converter
When driving, pay sufficient attention to weather, road conditions, terrain and
traffic conditions, and be sure to observe traffic laws and/or regulations. Fail-
ure to do so may cause an unexpected accident, resulting in death or seri-
ous injury.
NOTICE
If the fuel filter warning light comes on (diesel engine only)
Never drive the vehicle with the warning light on. Continued driving with
water accumulated in the fuel filter will damage the fuel injection pump.
When the DPF system warning light comes on (diesel engine with a
DPF system)
If the DPF system warning light is left on without performing cleaning, after
an additional 100 to 300 km (62 to 187 miles), the malfunction indicator lamp
may come on. If this happens, have the vehicle inspected by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional immediately.
