*: Driver's and front passen
ger's seat belt buzzer:
The driver's and front passenger's seat belt buzzer sounds to alert the driver
and front passenger that his or her seat belt is not fastened. Once the engine
switch is turned to the “ON” or “START” position (vehicles without a smart
key system) or the “POWER” switch is turned to ON mode (vehicles with a
smart key system), the buzzer sounds for 6 seconds. If the vehicle reaches a
speed of 12 mph (20 km/h), the buzzer sounds once. If the seat belt is still
unfastened after 30 seconds, the buzzer will sound intermittently for 10 sec-
onds. Then, if the seat belt is still unfastened, the buzzer will sound in a dif-
ferent tone for 20 more seconds.
■ SRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors, side impact sensors, driver's seat belt buckle switch, front passen-
ger occupant classification system (ECU and sensors), “AIR BAG ON” indi-
cator light, “AIR BAG OFF” indicator light, front passenger's seat belt buckle
switch, seat belt pretensioner assemblies, airbags, interconnecting wiring
and power sources. ( P. 432)
■ 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.
■ Electric power steering system wa rning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily drops, the electric power st eering system warning light may come on
and the warning buzzer may sound.

■If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank cap becomes
loose. If the fuel tank cap is loose, tighten it securely. The malfunction indica-
tor lamp will go off after several trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your Toyota 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.

Utilisation correcte des ceintures de sécurité
●Déroulez la sangle diagonale
de telle sorte qu'elle passe
bien sur l'épaule, sans pour
autant être en contact avec le
cou ou glisser de l'épaule.
● Placez la sangle abdominale
le plus bas possible sur les
hanches.
● Réglez la position du dossier
de siège. Asseyez-vous le dos
le plus droit possible et calez-
vous bien dans le siège.
● Ne vrillez pas la ceinture de
sécurité.

AT T E N T I O N
■Lorsque vous utilisez ou rangez la ceinture de sécurité du siège
central arrière
●N’utilisez pas la ceinture de sécurité du
siège arrière central lorsque l’une des
boucles est détachée.
Si vous n’attachez qu’une des boucles,
il y a risque de blessures graves voire
mortelles en cas de freinage brusque
ou de collision.
Entretien et soin
■Ceintures de sécurité
Nettoyez avec un chiffon ou une éponge humectée d'eau savonneuse tiède.
Profitez de l'occasion pour vérifier régulièrement que les ceintures ne sont
pas effilochées, entaillées, ou ne paraissent pas exagérément usées.
AT T E N T I O N
■Détérioration et usure des ceintures de sécurité
Inspectez les ceintures de sécurité périodiquement. Contrôlez qu'elles ne
sont pas entaillées, effilochées, et que leurs ancrages ne sont pas
desserrés. N'utilisez pas une ceinture de sécurité défectueuse avant qu'elle
ne soit remplacée. Une ceinture de sécurité défectueuse n'apporte aucune
garantie de protection de l'occupant en cas d'accident.
