WARNING
■SRS airbag precautions
●If breathing becomes difficult after the SRS airbags have deployed, open a
door or side window to allow fresh air in, or leave the vehicle if it is safe to
do so. Wash off any residue as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
●Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front

5-5. Using the driving support systems
WARNING
■Before using LTA system
●Do not rely solely upon the LTA system. The LTA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigued, such
as from driving for a long period of time.
●Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
●When not using the LTA system, use the LTA switch to turn the system off.
■Situations unsuitable for LTA system
In the following situations, use the LTA switch to turn the system off. Failure
to do so may lead to an accident, resulting in death or serious injury.
●Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.
●Vehicle is driven on a snow-covered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Vehicle is driven in a temporary lane or restricted lane due to construction
work.
●Vehicle is driven in a construction zone.
●A spare tire, tire chains, etc. are equipped.
●When the tires have been excessively worn, or when the tire inflation pres-
sure is low.
●During emergency towing.
■Preventing LTA system malfunctions and operations performed by
mistake
●Do not modify the headlights or place stickers, etc. on the surface of the
lights.
●Do not modify the suspension etc. If the suspension etc. needs to be
replaced, contact your Toyota dealer.
●Do not install or place anything on the hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar, etc.).
●If your windshield needs repairs, contact your Toyota dealer.

ability of the sensor to correctly detect obstacles. Particular instances where
this may occur are listed below.
●There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
●The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen, the screen may show an
abnormal display, or obstacles may not be detected.
●The sensor is covered in any way.
●In harsh sunlight or intense cold weather

●The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing ultra-
sonic waves.

NOTICE
■When using a high pressure car wash
●When washing the vehicle, do not let water of the high pressure washer hit
directly or the vicinity of the camera. Due to the shock from the high pres-
sure water, it is possible the device may not operate as normal.
●Do not bring the nozzle tip close to boots (rubber or resin manufactured
cover), connectors or the following parts. The parts may be damaged if
they come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 11.9 in. (30 cm) away from the vehicle
body. Otherwise resin section, such as moldings and bumpers, may be
deformed and damaged. Also, do not continuously hold the nozzle in the
same place.
●Do not spray the lower part of the windshield continuously. If water enters
the air conditioning system intake located near the lower part of the wind-
shield, the air conditioning system may not operate correctly.
●Do not wash the underside of the vehicle using a high pressure car
washer.
●Do not use the washer on the area around the charging port lid. Water
could get into the charging inlet and could damage the vehicle.
■When raising the windshield wiper arms
Make sure to hold the hook parts of the
wiper arms to raise them.
Do not hold only the wiper blades when
raising them, or it may cause deformation
of the wiper blades.

AVERTISSEMENT
■Précautions relatives aux coussins gonflables SRS
●Si vous avez de la difficulté à respirer après le déploiement des coussins
gonflables SRS, ouvrez une portière ou une glace latérale pour laisser
entrer l’air frais, ou quittez le véhicule si vous pouvez le faire en toute
sécurité. Dès que possible, nettoyez tous les résidus afin d’éviter les irrita-
tions cutanées.
●Si les emplacements de stockage des coussins gonflables SRS, tels que
le tampon de volant et les garnitures des montants avant et arrière, sont
endommagés ou fissurés, faites-les remplacer par votre concessionnaire
Toyota.
●Ne placez aucun objet, par exemple un coussin, sur le siège du passager
avant. Cela disperserait le poids du passager, ce qui empêcherait le cap-
teur de le détecter correctement. Cela pourrait empêcher le déploiement
des coussins gonflables SRS du passager avant en cas de collision.
■Modification et mise au rebut des composants du système de coussins
gonflables SRS
Ne mettez pas votre véhicule au rebut et n’effectuez aucune des modifica-
tions suivantes sans d’abord consulter votre concessionnaire Toyota. Les
coussins gonflables SRS pourraient fonctionner de manière incorrecte ou
se déployer (gonfler) accidentellement, ce qui serait susceptible d’occasion-
ner des blessures graves, voire mortelles.
●Installation, retrait, démontage et réparation des coussins gonflables SRS
●Réparations, modifications, retrait ou remplacement du volant, du tableau
de bord, de la planche de bord, des sièges ou du capitonnage des sièges,
des montants avant, latéraux et arrière, des brancards de pavillon, des
panneaux des portières avant, des garnitures des portières avant ou des
hautparleurs des portières avant
●Modifications du panneau de la portière avant (comme le perforer)
●Réparations ou modifications de l’aile avant, du pare-chocs avant ou du
côté de l’habitacle
●Installation d’une protection de calandre (barre safari, barre kangourou,
etc.), de lames de déneigement, de treuils ou d’un porte-bagages de toit
●Modifications du système de suspension du véhicule
●Installation d’appareils électroniques tels qu’un émetteur-récepteur radio
ou un lecteur de CD
●Modifications à votre véhicule pour une personne aux capacités physiques
