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
airbags for the front passenger may not deploy in the event of a collision.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your Toyota dealer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars, roof side rails, front door panels, front door trims or front door
speakers
● Modifications to the front door panel (such as making a hole in it)
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment
● Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows,
winches or roof luggage carrier

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.

● When the tires have been excessively worn, or when the tire inf lation pres-
sure is low.
● During emergency towing.

● 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 fa ire en toute
