WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation p ressure
label (tire and load information label). (If your vehicle has t ires of a dif-
ferent size than the size indica ted on the vehicle placard or tire inflation
pressure label [tire and load information label], you should de termine
the proper tire inflation p ressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS -tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Acco rdingly,
when the low tire pressure telltale (tire pressure warning ligh t) illumi-
nates, you should stop and check your tires as soon as possible , and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread lif e, and may
affect the vehicle’s handl ing and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintena nce, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicato r to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) mal func-
tion indicator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the tell tale will
flash for approximately one mi nute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle star t-ups
as long as the malfunction exists . When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tir e pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or al ternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure w arning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning sys tem) to
continue to function properly.

4647-2. 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. 505)
■ 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.

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 clot hing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap and the coolant reservoir cap wh ile 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.

4908-1. 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 gon flables
SRS.
Le non-respect de ces précautions peut occasionner des blessure s 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 supplémentaire s 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 mortelle s, si le
conducteur se trouve très près du coussin gonflable. L'autorité fédérale
chargée de la sécurité routière aux États-Unis (NHTSA) conseill e:
La zone à risque du coussin gonflable conducteur se situant dan s les pre-
miers 2 à 3 in. (50 à 75 mm) de déploiement, vous placer à 10 i n. (250
mm) de votre coussin gonflable conducteur vous garantit une mar ge de
sécurité suffisante. Cette distance est à mesurer entre le cent re du volant
et le sternum. Si vous êtes assis à moins de 10 in. (250 mm), vous 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 gran d
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 remonte z 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 que
de 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.

AVERTISSEMENT
■Précautions relatives aux coussins gonflables SRS
● Si un cache en vinyle est placé sur la zone où le coussin gonfl able 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 détecter correcte-
ment le poids du passager. En conséquence, les coussins gonflab les fron-
taux SRS du passager avant risquent de ne pas se déployer en ca s de
collision.
