fuel TOYOTA COROLLA iM 2017 11.G Owner's Manual

2326-2. Maintenance
COROLLA iM_U (OM12K64U)
The OBD system determines that a problem exists somewhere in the
emission control system. Your vehicle may not pass the I/M test and
may need to be repaired. Contact your Toyota dealer to service the
vehicle.
●When the battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may
not be completely set.
●When the fuel tank cap is loose
The malfunction indicator lamp illuminates, indicating a temporary
malfunction, and your vehicle may not pass the I/M test.
An OBD system error code will not be cleared unless the vehicle is
driven 40 or more times.
Contact your Toyota dealer to prepare the vehicle for re-testing.
Emission inspection and maintenance (I/M)
programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system
monitors the operation of the emission control system.
If the malfunction indicator lamp comes on
Your vehicle may not pass the I/M test in the following situations:
When the malfunction indicator lamp remains on after several
driving trips
If your vehicle does not pass the I/M test

2346-3. Do-it-yourself maintenance
COROLLA iM_U (OM12K64U)
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fan and engine
drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■When working near the electric cooling fan or radiator grille
Be sure the engine switch is off. With the engine switch in the “ON” position,
the electric cooling fan may automatically start to run if the air conditioning
is on and/or the coolant temperature is high. (→P. 244)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

Maintenance and care
COROLLA iM_U (OM12K64U)
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to deflate.
After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once
a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drivetrain
If a tire needs frequent inflating, have it checked by your Toyota dealer.

Follow the procedure below to restart the engine after the system is
activated.
Turn the engine switch to the “ACC” or “LOCK” position.
Restart the engine.
Fuel pump shut off system
To minimize the risk of fuel leakage when the engine stalls or
when an airbag inflates upon collision, the fuel pump shut off
system stops the supply of fuel to the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.

tion sensor may cause the warning light to flash and the warning buzzer to
sound 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.

WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a dif-
ferent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pressure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicator to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) malfunc-
tion indicator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tire pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.

3147-2. Steps to take in an emergency
COROLLA iM_U (OM12K64U)
One of the following may be the cause of the problem:
●There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
●The engine may be flooded.
Try to restart the engine again following correct starting procedures.
(→P. 128)
●There may be a malfunction in the engine immobilizer system.
(→P. 66)
One of the following may be the cause of the problem:
●The battery may be discharged. (→P. 315)
●The battery terminal connections may be loose or corroded.
One of the following may be the cause of the problem:

●The battery may be discharged. (→P. 315)
Contact your Toyota dealer if the problem cannot be repaired, or if repair
procedures are unknown.
If the engine will not start
If the engine will not start even though correct starting proce-
dures are being followed (→P. 128), consider each of the follow-
ing points:
The engine will not start even though the starter motor operates
normally.
The starter motor turns over slowly, the interior lights and head-
lights are dim, or the horn does not sound or sounds at a low
volume.
The starter motor does not turn over, the interior lights and head-
lights do not turn on, or the horn does not sound.
