■Front passenger detection sensor, passenger seat belt reminder and
warning buzzer
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and the warning
buzzer to sound even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■ If the malfunction indicator lamp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after taking driving trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your Scion dealer as soon as possible.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
Pushing the tire pressure warning reset switch will not turn off the tire
pressure warning light.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflat ion pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire
The compact spare tire is not equipped with a tire pressure warning
valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire has been replaced with the spare
tire. Replace the spare tire with the re paired tire and adjust the tire infla-
tion pressure. The tire pressure wa rning light will go off after a few min-
utes.

■The compact spare tire
●The compact spare tire saves in your luggage compartment.
●Its lighter weight helps to enhance fuel economy.
●It permits easier installation in case of a flat tire.
●Make sure to check the tire inflation pressu re of the compact spare
tire. ( P. 340)
■After completing the tire change
The tire pressure warnin g system must be reset. ( P. 239)
■When using the compact spare tire
As the compact spare tire is not equipped with a tire pressure warning
valve and transmitter, low inflation pressure of the spare tire will not be
indicated by the tire pressure warn ing system. Also, if you replace the
compact spare tire after the tire pressure warning light comes on, the
light remains on.

CAUTION
■Using the tire jack
Improper use of the tire jack may cause the vehicle to suddenly fall off
the jack, leading to death or serious injury.
●Do not use the tire jack for any purpose other than replacing tires or
installing and removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat
tire.
Do not use it on other vehicles, and do not use other tire jacks for
replacing tires on this vehicle.
●Always check that the tire jack is securely set to the jack point.
●Do not put any part of your body under the vehicle while it is supported
by the jack.
●Do not start or run the engine while your vehicle is supported by the
jack.
●Do not raise the vehicle while someone is inside.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a hei ght greater than that required to
replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
Take particular care when lowering the vehicle to ensure that no one
working on or near the vehicle may be injured.

CAUTION
■Replacing a flat tire
Observe the following precautions to reduce the risk of death or serious
injury:
●Do not touch the disc wheels or the area around the brakes immedi-
ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around
the brakes will be extremely hot.
Touching these areas with hands, feet
or other body parts while changing a tire, etc. may result in burns.
●Have the wheel nuts tightened with a torque wrench to 76 ft•lbf
(103 N
•m, 10.5 kgf•m) as soon as possible after changing wheels.
●When installing a tire, only use whee l nuts that have been specifically
designed for that wheel.
●If there are any cracks or deformatio ns in the bolt screws, nut threads
or bolt holes of the wheel, have the vehicle inspected by your Scion
dealer.
Failure to follow these precautions could cause the wheel nuts to loosen
and the tire to fall off, result ing in death or serious injury.
■When installing the wheel nuts
Be sure to install the wheel nuts with the tapered end facing inward.
( P. 251)
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in
their storage location to reduce the po ssibility of personal injury during a
collision or sudden braking.
■When stowing the flat tire
●Make sure the rear seats are in their original position.
●When carrying the flat tire, secure it using a tire tie-down belts. Other-
wise, the flat tire may fly out in case of the sudden braking or an acci-
dent, resulting in death or serious injury.

Votre véhicule est doté de COUSSINS GONFLABLES ÉVOLUÉS
dont la conception s’appuie sur les normes de sécurité des véhicules
à moteur américains (FMVSS208). Le module de capteur de coussin
gonflable (ECU) contrôle le déploiement des coussins gonflables en
fonction des informations obtenues des capteurs et d’autres élé-
ments affichés dans le diagramme des composants du système ci-
dessus. Ces informations comprennent des données relatives à la
gravité de l’accident et aux occupants. Au moment du déploiement
des coussins gonflables, une réaction chimique se produit dans les
gonfleurs de coussin gonflable et les coussins gonflables se remplis-
sent rapidement d’un gaz non toxique pour aider à limiter le mouve-
ment des occupants.Capteurs de coussin gon-
