For safety and security
WARNING
●If breathing becomes difficult
after the SRS airbags have
deployed, open a door or win-
dow to allow fresh air in, or
leave the vehicle if it is safe to
do so. Wash off any residue as
soon as possible to prevent skin
irritation.
●If the areas where the SRS air-
bags are stored, such as the
steering wheel pad and front
and rear pillar garnishes, are
damaged or cracked, have
them replaced by your Toyota
dealer.
●Do not place anything, such as
a cushion, on the front passen-
ger’s seat. Doing so will
disperse the passenger’s
weight, which prevents the sen-
sor from detecting the passen-
ger’s weight properly. As a
result, the SRS front airbags for
the front passenger may not
deploy in the event of a colli-
sion.
■Modification and disposal of
SRS airbag system compo-
nents
Do not dispose of your vehicle or
perform any of the following modi-
fications without consulting your
Toyota dealer. The SRS airbags
may malfunction or deploy
(inflate) accidentally, causing
death or serious injury.

bly and repair of the SRS air-
bags

tion to the surrounding condi-
tions and operating the steering
wheel to correct the path of the
vehicle. Also, the driver must
take adequate breaks when
fatigued, such as from driving
for a long period of time.
●Failure to perform appropriate
driving operations and pay care-
ful attention may lead to an
accident, resulting in death or
serious injury.
●When not using the LDA sys-
tem, use the LDA switch to turn
the system off.

In the following situations, use the
LDA switch to turn the system off.
Failure to do so may lead to an

face which is slippery due to
rainy weather, fallen snow,
freezing, etc.

WARNING
●When driving over roads with
potho
les or uneven surfaces
■TRAC/VSC may not operate
effectively when
Directional control and power may
not be achievable while driving on
slippery road surfaces, even if the
TRAC/VSC system is operating.
Drive the vehicle carefully in con-
ditions where stability and power
may be lost.
■Active Cornering Assist does
not
operate effectively when
●Do not overly rely on Active
Cornering Assist. Active Corner-
ing Assist may not operat
eef

fectively when accelerating
down slopes or driving on slip-
pery road surfaces.
●When Active Cornering Assistfr equently operates, Active Cor-
nering Assist may tempor
arily
stop

operating to ensure proper
operation of the brakes,
TRAC
and

VSC.
■Hill-start assist control does
not
operate effectively when
●Do not overly rely on hill-start
a
ssist control. Hill-start assist
control may not operate effec-
tively on steep inclines an
d
roads

covered with ice.
●Unlike the parking brake,hill-start assist control is not
intend

ed to hold the vehicle sta-
tionary for an extended period
of time. Do not attempt to
use
hill-s

tart assist control to
hold
th

e vehicle on an incline, as
doing so may lead to an acci-
dent.
■When the TRAC/VSC is acti-
vated
The slip indicato r light flashes.
Always drive carefully. Reckless
driving may cause an accident.
Exercise particular care when the
indicator light flashes.
■When the TRAC/VSC systems
a

re turned off
Be especially careful and drive at
a speed appropriate to the road
conditions. As these are the sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn
the TRAC/VSC systems off
unless necessary.
■Secondary Collision Brake
Do not overly rely on the Second-
ary Collision Brake. This system
is designed to help reduce the
possibility of furt her damage due
to a secondary collision, however,
that effect changes according to
various conditions. Overly relying
on the system may result in death
or serious injury.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation pressure level.
The ABS, TRAC and VSC sys-
tems will not function correctly if
different tires are installed on the
vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.

4227-1. Maintenance and care
COROLLA H/B_U
Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.
 If dirt cannot be removed,
wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.
Wring out any excess water
from the cloth and thoroughly
wipe off remaining traces of
detergent and water.
■Shampooing the carpets
There are several commercial foam-
ing-type cleaners available. Use a
sponge or brush to apply the foam.
Rub in overlapping circles. Do not
use water. Wipe dirty surfaces and
let them dry. Excellent results are
obtained by keeping the carpet as
dry as possible.
■Handling the seat belts
Clean with mild soap and lukewarm
water using a cloth or sponge. Also
check the belts periodically for
excessive wear, fraying or cuts.
NOTICE
●Do not bring the nozzle tip close
to boots (rubber or resin manu-
factured cover), connectors or
the following parts. The parts
may be damaged if they come
into contact with high-pressure
water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at
least 11.9 in. (30 cm) away from
the vehicles body. Otherwise
resin section, such as moldings
and bumpers, may be deformed
and damaged. Also, do not con-
tinuously hold the nozzle in the
same place.
●Do not spray the lower part of
the windshield continuously. If
water enters the air conditioning
system intake located near the
lower part of the windshield, the
air conditioning system may not
operate correctly.
●Do not wash the underside of
the vehicle using a high pres-
sure car washer.
Cleaning and protect-
