conditions and vehicle specifica-
tions.

A buzzer may sound when a mes-
sage is displayed.
The buzzer may not be audible if the
vehicle is in a noisy location or if the
audio system volume is high.
■If “Engine Oil Level Low Add or
Replace” is displayed
The engine oil leve l is low. Check
the level of the engine oil, and add if necessary.
This message may appear if the

■If “Engine Stopped Steering
Power Low” is displayed
This message is displayed if the
engine is stopped while driving.
When steering wheel operations are
heavier than usual, grip the steering
wheel firmly and operate it using
more force than usual.
■If “Auto Power OFF to Conserve
Battery” is displayed
Power was cut off due to the auto-
matic power off function. Next time
when starting the engine, increase
the engine speed slightly and main-
tain that level for approximately 5
minutes to rechar ge the battery.
■If “Headlight System Malfunc-
tion Visit Your Dealer” is dis-
played
The following systems may be mal-
functioning. Have the vehicle
inspected by your Toyota dealer
immediately.
●The LED headlight system
●AFS (Adaptive Front-lighting Sys-
tem) (if equipped)
●The automatic headlight leveling
system (if equipped)
●Automatic High Beam
■If a message that indicates the
malfunction of front camera is
displayed
The following systems may be sus-
pended until the problem shown in
the message is resolved. ( P.176,
472)
●PCS (Pre-Collision system)
●LTA (Lane Tracing Assist) (if
equipped)
●LDA (Lane Departure Alert with
steering control) (if equipped)
If a war ning message

If a warning message is dis-
played again after the
appropriate actions have
been performed, contact
your Toyota dealer.

ing message is displayed,
take the appropriate correc-
tive action for the warning
light. ( P.472)

4928-2. Steps to take in an emergency
COROLLA H/B_U
■If the tire is inflated to more
than the specified air pressure
1 Disconnect the hose from the
valve.
2 Install the air release cap to the
end of the hose and push the
protrusion on the air release cap
into the tire valve to let some air
out.
3 Disconnect the hose from the
valve, remove the air release cap
from the hose and then recon-
nect the hose.
4 Turn the compressor switch on
and wait for several seconds,
and then turn it off. Check that
the air pressure indicator shows
the specified air pressure.
( P.519)
If the air pressure is under the des-
ignated pressure, turn the compres-
sor switch on again and repeat the
inflation procedure until the speci-
fied air pressure is reached.
■After a tire is repaired with the
emergency tire puncture repair
kit
●The tire pressure warning valve
and transmitter should be
replaced.
●Even if the tire inflation pressure is
at the recommended level, the tire
pressure warning light may come
on/flash.
WARNING
■Do not drive the vehicle with
a flat tire
Do not continue driving with a flat
tire.
Driving even a short distance with
a flat tire can damage the tire and
the wheel beyond repair.
Driving with a flat tire may cause a
circumferential groove on the side
wall. In such a case, the tire may
explode when using a repair kit.
■When fixing the flat tire
●Stop your vehicle in a safe and
flat area.
●Do not touch the wheels or the
area around the brakes immedi-
ately after the vehicle has been
driven.
After the vehicle has been
driven, the wheels and the area
around the brakes may be
extremely hot. Touching these
areas with hands, feet or other
body parts may result in burns.
●Connect the valve and hose
securely with the tire installed
on the vehicle. If the hose is not
properly connected to the valve,
air leakage may occur as seal-
ant may be sprayed out.
●If the hose comes off the valve
while inflating the tire, there is a
risk that the hose will move
abruptly due to air pressure.
●After inflation of the tire has
completed, the sealant may
splatter when the hose is dis-
connected or some air is let out
of the tire.
●Follow the operation procedure
to repair the tire. If the proce-
dures not followed, the sealant
may spray out.

two or three times in the
order shown in the illustra-
tion.
Tightening torque:
76 ft•lbf (103 N•m, 10.5 kgf•m)
5Stow the flat tire, tire jack and
all tools.
■The compact spare tire
●The compact spare tire is identi-
fied by the label “TEMPORARY USE ONLY” on the tire sidewall.
Use the compact spare tire tempo-
rarily, and only in an emergency.
●Make sure to check the tire infla-
tion pressure of the compact
spare tire. (
P.519)
■When the compact spare tire is
equipped
The vehicle becomes lower when
driving with the compact spare tire
compared to when driving with stan-
dard tires.
■After completing the tire
change
The tire pressure warning system
must be reset. ( P.448)
■When using the compact spare
tire
As the compact spare tire is not
equipped with a tire pressure warn-
ing valve and transmitter, low infla-
tion pressure of the spare tire will
not be indicated by the tire pressure
warning system. Also, if you replace
the compact spare tire after the tire
pressure warning light comes on,
the light remains on.
■If you have a flat front tire on a
road covered with snow or ice
(vehicles with a compact spare
tire)
Install the compact spare tire on one
of the rear wheels of the vehicle.
Perform the following steps and fit
tire chains to the front tires:
1 Replace a rear tire with the com-
pact spare tire.
2 Replace the flat front tire with the
tire removed from the rear of the
vehicle.
3 Fit tire chains to the front tires.
■When reinstalli ng the wheel
ornament (steel wheels except
compact spare tire)

ment with the valve stem as shown

WARNING
■When removing the battery
terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, le ading to a fire
in addition to electrical shocks
and death or serious injury.
■Avoiding battery fires or
explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the battery:
●Make sure each jumper cable is
connected to the correct termi-
nal and that it is not unintention-
ally in contact with any other
than the intended terminal.
●Do not allow the other end of
the jumper cable connected to
the “+” terminal to come into
contact with any other parts or
metal surfaces in the area, such
as brackets or unpainted metal.
●Do not allow the + and - clamps
of the jumper cables to come
into contact with each other.
●Do not smoke, use matches,
cigarette lighters or allow open
flame near the battery.
■Battery precautions
The battery contains poisonous
and corrosive acidic electrolyte,
while related parts contain lead
and lead compounds. Observe
the following precautions when
handling the battery:
●When working with the battery,
always wear safety glasses and
take care not to allow any bat-
tery fluids (acid) to come into
contact with skin, clothing or the
vehicle body.
●Do not lean over the battery.
●In the event that battery fluid
comes into contact with the skin
or eyes, immediately wash the
affected area with water and
seek medical attention. Place a
wet sponge or cloth over the
affected area until medical
attention can be received.
●Always wash your hands after
handling the battery support,
terminals, and other bat-
tery-related parts.
●Do not allow children near the
battery.
NOTICE
■When handling jumper cables
When connecting the jumper
cables, ensure that they do not
become entangled in the cooling
fan or engine drive belt.
