4907-2. Steps to take in an emergency
■Starting the engine when t he 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 electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic .
■ When the battery is r emoved or discharged
● Information stored in the ECU is cleared. When the battery is d epleted, have
the vehicle inspected at your Toyota dealer.
● Some systems may require initialization. ( P. 533)
■ When removing the battery terminals
When the battery terminals are removed, the information stored in the ECU is
cleared. Before removing the battery terminals, contact your Toyota dealer.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long t ime, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ When recharging or replacing the battery
●In some cases, it may not be possible to unlock the doors using the smart
key system when the battery is discharged. Use the wireless rem ote 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 memorized by the vehicle. When the ba ttery is
reconnected, the system will return to the mode it was in befor e the battery
was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, 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 (L N3), 20 hour
rate capacity (20HR) is equivalent (70Ah) or greater, and perfo rmance rating
(CCA) is equivalent (603A) or greater.
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period w here the vehi-
cle is not used is a short time, the battery may discharge and the engine
may not be able to start.
● For details, consult your Toyota dealer.

4947-2. Steps to take in an emergency
Start the engine and turn the air conditioning system on to check
that the radiator cooling fan operates and to check for coolant leaks
from the radiator or hoses.
The fan operates when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fan is operating by checking 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 operate in freezing tem-
peratures.)
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 neare st Toyota dealer.
WARNING
■To prevent an accident or injury when inspecting under the hood of
your vehicle
Observe the following precautions.
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 ho od until
the steam has subsided. The engine compartment may be very hot.
● Keep hands and clothing (especially a tie, a scarf 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 radiator cap and the coolant reservoir cap while the
engine and radiator are hot.
High temperature steam or coolant could spray out.
NOTICE
■When adding engine coolant
Wait until the engine has cooled down before adding engine cool ant.
When adding coolant, do so slowly. 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 precautions:
● Avoid contaminating the coolant with foreign matter (such as sa nd or dust
etc.).
● Do not use any coolant additives.

5188-1. Specifications
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing
the tire’s resistance to the ge neration of heat and its ability to dissi-
pate heat when tested under contr olled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can c ause 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 passeng er
car tires must meet under the Fe deral Motor Vehicle Safety Stan-
dard 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 that it is pro perly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can c ause heat buildup and possible t ire
failure.

AVERTISSEMENT
■Précautions relatives aux coussins gonflables SRS
Respectez les précautions suivantes concernant les coussins gonflables
SRS.
Le non-respect de ces précautions peut occasionner des blessures graves,
voire mortelles.
● Le conducteur et tous les passagers du véhicule doivent porter correcte-
ment leur ceinture de sécurité.
Les coussins gonflables SRS sont des dispositifs supplémentaires à utili-
ser avec les ceintures de sécurité.
● Le coussin gonflable conducteur SRS se déploie avec une force c onsidé-
rable, 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 gonflable conducteur se situant dans les pre-
miers 2 à 3 in. (50 à 75 mm) de déploiement, vous placer à 10 in. (250
mm) de votre coussin gonflable conducteur vous garantit une mar ge 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), v ous pou-
vez changer votre position de conduite de plusieurs façons:
• Reculez votre siège le plus possible, de manière à pouvoir enc ore
atteindre confortablement les pédales.
• Inclinez légèrement le dossier du siège. Bien que les véhicules aient une conception différente, un grand
nombre de conducteurs peuvent s'asseoir à une distance de 10 in. (250
mm), même avec le siège conducteur complètement avancé, simple-
ment en inclinant un peu le dossier de siège. Si vous avez des difficul-
tés à voir la route après avoir incliné le dossier de votre siè ge, utilisez
un coussin ferme et antidérapant pour vous rehausser ou remontez le
siège si votre véhicule est équipé de cette fonction.
• Si votre volant est réglable, inclinez-le vers le bas. Cela a pour effet d'orienter le coussin gonflable en direction de votre poitrine plutôt quede votre tête et de votre cou.
Réglez votre siège selon les recommandations de la NHTSA ci-des sus,
tout en conservant le contrôle des pédales, du volant et la vue des com-
mandes du tableau de bord.

■Précautions relatives aux coussins gonflables SRS
● Si un cache en vinyle est placé sur la zone où le coussin gonflable de
genoux SRS se déploie, assurez-vous de le retirer.
● N'utilisez aucun accessoire de siège recouvrant les zones de dé ploiement
des coussins gonflables latéraux SRS, car il risque de gêner le déploie-
ment des coussins gonflables SRS. De tels accessoires peuvent e mpê-
cher les coussins gonflables latéraux de fonctionner correcteme nt,
désactiver le système ou entraîner le déploiement accidentel de s coussins
gonflables latéraux, occasionnant des blessures graves, voire m ortelles.
● Évitez de faire subir des chocs ou des pressions excessives aux parties
renfermant les composants de coussins gonflables SRS ou aux por tes
avant.
En effet, cela pourrait entraîner un dysfonctionnement des cous sins gon-
flables SRS.
● Ne touchez aucun composant immédiatement après le déploiement ( gon-
flage) 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'éventuelles irritations
de la peau.
● Si les parties renfermant les coussins gonflables SRS, comme le s garni-
tures du volant et des montants avant et arrière, sont endommag ées ou
craquelées, faites-les remplacer par votre concessionnaire Toyo ta.
● Ne placez rien sur le siège du passager avant, comme un coussin par
exemple. Cela a pour conséquence de répartir le poids du passag er sur
toute la surface du siège, ce qui empêche le capteur de détecte r correcte-
ment le poids du passager. En conséquence, les coussins gonflables fron-
taux SRS du passager avant risquent de ne pas se déployer en cas de
collision.
