When trouble arises
WARNING
●Keep back from the tire while it
is being repaired, as there is a
chance of it bursting while the
repair operation is being per-
formed. If you notice any cracks
or deformation of the tire, turn
off the compressor switch and
stop the repair operation imme-
diately.
●The repair kit may overheat if
operated for a long period of
time. Do not operate the repair
kit continuously for more than
40 minutes.
●Parts of the repair kit become
hot during operation. Be careful
handling the repair kit during
and after operation. Do not
touch the metal part connecting
the bottle and the compressor. It
will be extremely hot.
●Do not attach the vehicle speed
warning sticker to an area other
than the one indicated. If the
sticker is attached to an area
where an SRS airbag is located,
such as the pad of the steering
wheel, it may prevent the SRS
airbag from operating properly.
■Driving to spread the liquid
sealant evenly
Observe the following precautions
to reduce the risk of accidents.
Failing to do so may result in a
loss of vehicle control and cause
death or serious injury.
●Drive the vehicle carefully at a
low speed. Be especially careful
when turning and cornering.
●If the vehicle d oes not drive
straight or you feel a pull
through the steering wheel, stop
the vehicle and check the fol-
lowing.
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If the tire inflation pressure is 19 psi (130
kPa, 1.3 kgf/cm
2 or bar) or less,
the tire may be severely dam-
aged.
NOTICE
■When performing an emer-
gency repair
●A tire should only be repaired
with the emergency tire punc-
ture repair kit if the damage is
caused by a sharp object such
as nail or screw passing through
the tire tread.
Do not remove th e sharp object
from the tire. Removing the
object may widen the opening
and disenable emergency repair
with the repair kit.
●The repair kit is not waterproof.
Make sure that the repair kit is
not exposed to water, such as
when it is being used in the rain.
●Do not put the repair kit directly
onto dusty ground such as sand
at the side of the road. If the
repair kit vacuums up dust etc.,
a malfunction may occur.
■Precautions for the emer-
gency tire puncture repair kit
●The repair kit power source
should be 12 V DC suitable for
vehicle use. Do not connect the
repair kit to any other source.
●If fuel splatters on the repair kit,
the repair kit may deteriorate.
Take care not to allow fuel to
contact it.
●Place the repair kit in a storage
to prevent it from being exposed
to dirt or water.
●Store the repair kit in the lug-
gage compartment out of reach
of children.

vehicle.
5 Open and close any of the
doors of your vehicle with the
engine switch OFF.
6 Maintain the engine speed of
the second vehicle and start
the engine of your vehicle by
turning the engine switch to
ON.
7 Once the vehicle’s engine
has started, remove the
jumper cables in the exact
reverse order from which
they were connected.
Once the engine starts, have the
vehicle inspected at your Toyota
dealer as soon as possible.
■Starting the engine when the
battery is discharged
The engine cannot be started by
push-starting.
■To prevent battery discharge
●Turn off the headlights and the
audio system while the engine is
off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■When the battery is removed or
discharged
●Information stor ed in the ECU is
cleared. When the battery is
depleted, have the vehicle
inspected at you r Toyota dealer.
●Some systems may require initial-
ization. ( P.539)
■When removing the battery ter-
minals
When the battery terminals are
removed, the information stored in
the ECU is cleared. Before remov-
ing the battery term inals, contact
your Toyota dealer.
■Charging the battery
The electricity stored in the battery
will discharge grad ually even when
the vehicle is not in use, due to nat-
ural discharge and the draining
effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the battery may discharge,
and the engine may be unable to
start. (The battery recharges auto-
matically during driving.)
■When recharging or replacing
the battery
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the bat-
tery is discharged. Use the wire-
less remote control or the
mechanical key to lock or unlock
the doors.
●The engine may not start on the
first attempt after the battery has
recharged but will start normally
after the second attempt. This is
not a malfunction.
●The engine switch mode is memo-
rized by the vehicle. When the
battery is reconnected, the system
will return to the mode it was in
before the bat tery was dis-
charged. Before disconnecting the
battery, turn the engine switch off.
If you are unsure what mode the
engine switch wa s in before the
battery discharged, be especially
careful when reconnecting the
battery.
■When replacing the battery
●Use a battery that conforms to
European regulations.
●Use a battery that the case size is
same as the previous one (LN2),
20 hour rate capacity (20HR) is

6 Start the engine and turn the
air conditioning system on to
check that the radiator cool-
ing fan operates and to check
for coolant leaks from the
radiator or hoses.
The fan operates when the air con-
ditioning system is turned on imme-
diately after a cold start. Confirm
that the fan is op erating by check-
ing the fan sound and air flow. If it is
difficult to check these, turn the air
conditioning system on and off
repeatedly. (The fan may not oper-
ate in freezing temperatures.)
7 If the fan is not operating:
Stop the engine immediately
and contact your Toyota
dealer.
If the fan is operating:
Have the vehicle inspected at
the nearest Toyota dealer.
WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions. Failure to do so may result
in serious injury such as burns.
●If steam is seen coming from
under the hood, do not open the
hood until the steam has sub-
sided. The engine compart-
ment may be very hot.
●Keep hands and clothing (espe-
cially a tie, a sca rf or a muffler)
away from the fan and belts.
Failure to do so may cause the
hands or clothing to be caught,
resulting in serious injury.
●Do not loosen the coolant reser-
voir caps while the engine and
radiator are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the
engine has cooled down suffi-
ciently. Adding cool coolant to a
hot engine too quickly can cause
damage to the engine.
■To prevent damage to the
cooling system
Observe the following precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust etc.).
●Do not use any coolant additive.

5249-1. Specifications
COROLLA H/B_Uwould wear one and a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative perfo
rmance of tires
depends upon the actual conditions
of their use. Performance may differ
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
■Traction AA, A, B, C
The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.
A tire marked C may have poor
traction performance.
Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material
of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume tha t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.

Coussin gonflable de genoux du conducteur
Témoin d'avertissement SRS
Capteurs d'impact avant
Ensemble de capteurs de coussins gonflables
Votre véhicule est équipé de COUSSINS GONFLABLES INTELLI-
GENTS conçus selon les normes de sécurité américaines applica-
bles aux véhicules à moteur (FMVSS208). L'ensemble de capteurs
de coussins gonflables (ECU) régule le déploiement des coussins
gonflables sur la base des informa tions qu'il reçoit des capteurs,
etc., indiqués ci-dessus dans le schéma illustrant les composants du
système. Parmi ces informations figurent la gravité du choc et l'occu-
pation du véhicule par les passagers. Le déploiement rapide des
coussins gonflables est obtenu au moyen d'une réaction chimique
dans les dispositifs pyrotechniques, qui produit un gaz inoffen sif per-
mettant d'amortir le mouvement des occupants.
WARNING
■Précautions relatives aux
coussins gonflables SRS
Respectez les précautions suiva-
ntes concernant les coussins gon-
flables SRS.
Le non-respect de ces précau-
tions peut occasionner des bless-
ures graves, voire mortelles.
●Le conducteur et tous les pas-
sagers du véhicule doivent por-
ter correctement leur ceinture
de sécurité.
Les coussins gonflables SRS
sont des disposit ifs supplémen-
taires à utiliser avec les cein-
tures de sécurité.
●Le coussin gonflable conduc-
teur SRS se déploie avec une
force considérable, pouvant
occasionner des blessures
graves, voire mortelles, si le
conducteur se trouve très près
du coussin gonflable. L'autorité
fédérale chargée de la sécurité
routière aux États-Unis
(NHTSA) conseille:
La zone à risque du coussin gon-
flable conducteur se situant dans
les premiers 2 à 3 in. (50 à 75
mm) de déploiement, vous placer
à 10 in. (250 mm) de votre cous-
sin gonflable conducteur vous
garantit une marge de sécurité
suffisante. Cette distance est à
mesurer entre le centre du volant
et le sternum. Si vous êtes assis à
moins de 10 in. (250 mm), vous
pouvez changer votre position de
conduite de plusieurs façons:
• Reculez votre siège le plus pos- sible, de manière à pouvoir
encore atteindre confortable-
ment les pédales.

WARNING
●Ne fixez rien aux portes, à la
vitre du pare-brise, aux vitres
latérales, aux montants avant et
arrière, au rail latéral de toit et à
la poignée de maintien.
●Ne suspendez aucun cintre ou
objet dur aux crochets à vête-
ments. Tous ces objets pour-
raient se transformer en
projectiles et c auser des bless-
ures graves, voire mortelles en
cas de déploiement des couss-
ins gonflables rideaux SRS.
●Si un cache en vinyle est placé
sur la zone où le coussin gon-
flable de genoux du conducteur
SRS se déploie, assurez-vous
de le retirer.
●N'utilisez aucun accessoire de
siège recouvrant les zones de
déploiement des coussins gon-
flables latéraux SRS et du cous-
sin gonflable de coussin de
siège SRS, car il risque de
gêner le déploiement des cous-
sins gonflables SRS. De tels
accessoires peuvent empêcher
les coussins gonflables latéraux
et le coussin gonflable de cous-
sin de siège de s'activer cor-
rectement, désactiver le
système ou entraîner le déploie-
ment accidentel des coussins
gonflables latéraux et du cous-
sin gonflable de coussin de
siège, occasionnant des bless-
ures graves, voire mortelles.
●Évitez de faire subir des chocs
ou des pressions excessives
aux parties renfermant les com-
posants de coussins gonflables
SRS ou aux portes avant.
En effet, cela pourrait entraîner
un dysfonctionnement des
coussins gonflables SRS.
●Ne touchez aucun composant
immédiatement après le
déploiement (gonflage) des
coussins gonflables SRS, car ils
peuvent être chauds.
●Si vous avez des difficultés à
respirer après le déploiement
des coussins gonflables SRS,
ouvrez une porte ou une vitre
pour faire entrer de l'air frais, ou
bien descendez du véhicule si
cela ne présente pas de danger.
Essuyez tout résidu dès que
possible afin d'éviter d'éventu-
elles irritations de la peau.
●Si les parties renfermant les
coussins gonflables SRS,
comme les garnitures du volant
et des montants avant et
arrière, sont endommagées ou
craquelées, faites-les remplacer
par votre concessionnaire Toy-
ota.
●Ne placez rien sur le siège du
passager avant, comme un
coussin par exemple. Cela a
pour conséquence de répartir le
poids du passager sur toute la
surface du siège, ce qui
empêche le capteur de détecter
correctement le poids du pas-
sager. En conséquence, les
coussins gonflables frontaux
SRS du passager avant ris-
quent de ne pas se déployer en
cas de collision.
