engine TOYOTA COROLLA HATCHBACK 2022 (in English) Repair Manual

1644-1. Before driving
WA R N I N G
• When backing up, you may twist
your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly. This allows you
to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your
right foot. Depressing the brake pedal using your left foot may delay
response in an emergency, result-
ing in an accident.
●Do not drive the vehicle over or
stop the vehicle near flammable materials.
The exhaust system and exhaust
gases can be extremely hot. These hot parts may cause a fire if there is
any flammable material nearby.
●During normal driving, do not turn
off the engine. Turning the engine
off while driving will not cause loss of steering or braking control, but
the power assist to these systems
will be lost. This will make it more difficult to steer and brake, so you
should pull over and stop the vehi-
cle as soon as it is safe to do so. However, in the event of an emer-
gency, such as if it becomes impos-
sible to stop the vehicle in the normal way: P. 5 0 2
●Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and
lose effectiveness. (P.182, 186)
●Do not adjust the positions of the
steering wheel, the seat, or the
inside or outside rear view mirrors while driving.
Doing so may result in a loss of
vehicle control.
●Always check that all passengers’ arms, heads or other parts of their
body are not outside the vehicle.
■When driving on slippery road
surfaces
●Sudden braking, acceleration and steering may cause tire slippage
and reduce your ability to control
the vehicle.
●Sudden acceleration, engine brak-
ing due to shifting, or changes in engine speed could cause the vehi-
cle to skid.
●After driving through a puddle,
lightly depress the brake pedal to
make sure that the brakes are func- tioning properly. Wet brake pads
may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not func-
tioning properly, steering control
may be affected.
■When shifting the shift lever
●Vehicles with a Multidrive: Do not let the vehicle roll backward while a
forward driving position is selected,
or roll forward while the shift lever is in R.
Doing so may cause the engine to
stall or lead to poor brake and steering performance, resulting in
an accident or damage to the vehi-
cle.
●Vehicles with a Multidrive: Do not
shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmis-
sion and may result in a loss of vehicle control.
●Do not shift the shift lever to R while
the vehicle is moving forward. Doing so can damage the transmis-
sion and may result in a loss of
vehicle control.

●Do not shift the shift lever to a driv-
ing position while the vehicle is
moving backward. Doing so can damage the transmis-
sion and may result in a loss of
vehicle control.
●Moving the shift lever to N while the
vehicle is moving will disengage the
engine from the transmission. Engine braking is not available
when N is selected.
●Vehicles with a Multidrive: Be care-
ful not to shift the shift lever with the
accelerator pedal depressed. Shift- ing the shift lever to any positions
other than P or N may lead to unex-
pected rapid acceleration of the vehicle that may cause an accident
and result in death or serious injury.
■If you hear a squealing or scrap-
ing noise (brake pad wear indica-
tors)
Have the front and rear brake pads
checked at the same time and
replaced by any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer as soon as
possible.
Rotor damage may result if the pads
are not replaced when needed.
It is dangerous to drive the vehicle
when the wear limits of the brake pads and/or those of the brake discs
are exceeded.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P (Multidrive) or N, the vehicle
may accelerate suddenly and unex-
pectedly, causing an accident.
●Vehicles with a Multidrive: In order to prevent accidents due to the
vehicle rolling away, always keep
depressing the brake pedal while the engine is running, and apply the
parking brake as necessary.
●If the vehicle is stopped on an
incline, in order to prevent acci-
dents caused by the vehicle rolling forward or backward, always
depress the brake pedal and
securely apply the parking brake as needed.
●Avoid revving or racing the engine.Running the engine at high speed
while the vehicle is stopped may
cause the exhaust system to over- heat, which could result in a fire if
combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette
lighters, spray cans, or soft drink cans in the vehicle when it is in the
sun.
Doing so may result in the follow- ing:
• Gas may leak from a cigarette
lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of glasses to
deform or crack.
• Soft drink cans may fracture, caus-
ing the contents to spray over the interior of the vehicle, and may also
cause a short circuit in the vehicle’s
electrical components.
●Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally
when luggage is loaded or the seat
is adjusted, causing a fire.

1664-1. Before driving
WA R N I N G
●Do not attach adhesive discs to the
windshield or windows. Do not
place containers such as air fresh- eners on the instrument panel or
dashboard. Adhesive discs or con-
tainers may act as lenses, causing a fire in the vehicle.
●Do not leave a door or window
open if the curved glass is coated with a metallized film such as a sil-
ver-colored one. Reflected sunlight
may cause the glass to act as a lens, causing a fire.
●Always apply the parking brake, shift the shift lever to P (vehicles
with a Multidrive), stop the engine
and lock the vehicle. Do not leave the vehicle unat-
tended while the engine is running.
If the vehicle is parked with the shift lever in P but the parking brake is
not set, the vehicl e may start to
move, possibly leading to an acci- dent.
●Do not touch the exhaust pipes while the engine is running or
immediately after turning the engine
off. Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise,
if you accidentally move the shift lever
or depress the accelerator pedal, this could cause an accident or fire due to
engine overheating. Additionally, if the
vehicle is parked in a poorly ventilated area, exhaust gases may collect and
enter the vehicle, leading to death or
a serious health hazard.
■When braking
●When the brakes are wet, drive
more cautiously.
Braking distance increases when the brakes are wet, and this may
cause one side of the vehicle to
brake differently than the other side. Also, the parking brake may
not securely hold the vehicle.
●If the brake booster device does not
operate, do not follow other vehi-
cles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible,
but the brake pedal should be depressed more firmly than usual.
Also, the braking distance will
increase. Have your brakes fixed immediately.
●Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses
up the reserve for the power-assisted brakes.
●The brake system consists of 2 indi-vidual hydraulic systems; if one of
the systems fails, the other will still
operate. In this case, the brake pedal should be depressed more
firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively
when a driven wheel is up in the air,
or the vehicle is stuck in sand, mud, etc. This may damage the driveline
components or propel the vehicle for-
ward or backward, causing an acci-
dent.

NOTICE
■When driving the vehicle (vehi-
cles with a Multidrive)
●Do not depress the accelerator and brake pedals at the same time dur-
ing driving, as this may restrain the
engine output.
●Do not use the accelerator pedal or
depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■When driving the vehicle (vehi-cles with a manual transmission)
●Do not depress the accelerator and
brake pedals at the same time dur- ing driving, as this may restrain the
engine output.
●Do not shift gears unless the clutch
pedal is fully depressed. After shift-
ing, do not release the clutch pedal abruptly. Doing so may damage the
clutch, transmission and gears.
●Observe the following precautions.
Failure to do so may cause exces-
sive premature wear or damage to the clutch, eventually making it diffi-
cult to accelerate and start off from
a stop. Have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
• Do not rest your foot on the clutch
pedal or depress it any time other
than when shifting. Doing so may cause clutch trouble.
• Do not use any gear other than the 1st gear when starting off and mov-
ing forward.
Doing so may damage the clutch.
• Do not use the clutch pedal to
adjust vehicle speed. Doing so may damage the clutch.
• When stopping the vehicle with the shift lever in a position other than N,
make sure to fully depress the
clutch pedal and stop the vehicle using the brakes.
●Do not shift the shift lever to R with-out the vehicle completely stopped.
Doing so may damage the clutch,
transmission and gears.
■When parking the vehicle (vehi-
cles with a Multidrive)
Always set the parking brake and shift
the shift lever to P. Failure to do so
may cause the vehicl e to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally
depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there
for an extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to
avoid damaging the wheels, under-
side of the vehicle, etc.
●Make sure to idle the engine imme-
diately after high-load driving. Stop the engine only after the
turbocharger has cooled down.
Failure to do so may cause damage to the turbocharger.
■If you get a flat tire while driving
A flat or damaged tire may cause the
following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the
vehicle.
●It may be difficult to control your vehicle.

may cause the following serious dam-
age to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water
immersion
In the event that you drive on a
flooded road and the vehicle becomes flooded or stuck in mud or
sand, be sure to have any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer check
the following:
●Brake function
●Changes in the quantity and quality of the engine oil, transaxle fluid,
clutch fluid, differential oil, etc.
●Lubricant condition for the bearings
and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.

Failure to do so may prevent the ped- als from being depressed properly,
may block the driver’s vision, or may
result in items hitting the driver or passengers, possibly causing an acci-
dent.
●Stow cargo and luggage in the lug-
gage compartment whenever pos-
sible.
●Do not stack cargo and luggage in
the luggage compartment higher than the seatbacks.
●When you fold down the rear seats, long items should not be placed
directly behind the front seats.

exceed the gross vehicle mass by more
than 100 kg (220.5 lb.). Exceeding this
weight is dangerous.
Maximum permissible rear axle
capacity
The weight borne by the rear axle
should not exceed the maximum per-
missible rear axle capacity by 15% or
more. Exceeding this weight is danger-
ous. The values for towing capacity
were derived from testing conducted at
sea level. Take note that engine output
and towing capacity will be reduced at
high altitudes.

operation of the connection
between the trailer and lights after
driving for a brief period as well as
before starting off.
■Practicing driving with a cou-
pled trailer
 Get the feel for turning, stopping
and reversing with the trailer
coupled by practicing in an area
with no or light traffic.
 When reversing with a coupled
trailer, hold the section of the
steering wheel nearest to you
and rotate clockw ise to turn the
trailer left or counterclockwise to
turn it right. Always rotate a little
at a time to prevent steering
error. Have someone guide you
when reversing to lessen the risk
of an accident.
■Increasing vehicle-to-vehicle
distance
At a speed of 10 km/h (6 mph), the
distance to the vehicle running
ahead of you should be equivalent
to or greater than the combined
length of your vehicle and trailer.
Avoid sudden braking that may
cause skidding. Otherwise, the
vehicle may spin out of control. This
is especially true when driving on
wet or slippery road surfaces.
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in th e trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the tr ailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor-
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre-
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut-
ing lane changes.
■Transmission information
Multidrive
To maintain engine braking effi-
ciency and charging system perfor-
mance when using engine braking,
do not use the transmission in D,

1764-1. Before driving
must be in M and select gear step 4
or lower. ( P. 1 8 2 )
Manual transmission
Refrain from driving in 6th gear to
maintain the effectiveness of
engine braking and to maintain
charging system performance.
■If the engine overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the engine overheating. If the
engine coolant temperature gauge
indicates that the engine is over-
heating, turn the air conditioning off
immediately, leave the road and
stop the vehicle in a safe place.
( P.560)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P
(Multidrive) and 1 or R (manual
transmission).
WA R N I N G
Follow all the instructions described in this section. Failure to do so could
cause an accident resulting in death
or serious injury.
■Trailer towing precautions
When towing, make sure that none of the weight limits are exceeded.
( P.171)
■Vehicle speed in towing
Observe the legal maximum speeds
for trailer towing.
■Before descending hills or long declines
Reduce speed and downshift. How-
ever, never downshift suddenly while descending steep or long downhill
grades.
■Operation of the brake pedal
Do not hold the brake pedal
depressed often or for long periods of time. Doing so may result in the brake
overheating or reduce braking effects.
■To avoid accident or injury
●Vehicles with a compact spare tire:
Do not tow a trailer when the com- pact spare tire is installed on your
vehicle.
●Vehicles with the emergency tire
puncture repair kit: Do not tow a
trailer when the tire installed is repaired with the emergency tire
puncture repair kit.
●Do not use the following systems
when trailer towing.
• Cruise control (if equipped)
• Dynamic radar cruise control (if
equipped)
• Dynamic radar cruise control with
full-speed range (if equipped)
