WARNING
■SRS airbag precautions
● If breathing becomes difficult after the SRS airbags have deplo yed, 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 t he sensor
from detecting the passenger’s weight properly. As a result, th e SRS front
airbags for the front passenger may not deploy in the event of  a collision.

without consulting your Toyota dealer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.

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  fatigu ed,  such
as from driving for a long period of time.
● Failure to perform appropriate driving operations and pay caref ul 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.

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  w ill  resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.) 
In  especially  cold  weather,  if  a  sensor  is  frozen,  the  screen  m ay  show  an
abnormal display, or obstacles may not be detected.
● The sensor is covered in any way.
● In harsh sunlight or intense cold weather
● On an extremely bumpy road, on an incline, on gravel, or on grass
● The  vicinity  of  the  vehicle  is  noisy  due  to  vehicle  horns,  moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
● The sensor is splashed with water or drenched with heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is leaning considerably to one side.
● The vehicle is equipped with a fender pole or wireless antenna.
● The vehicle is approaching a tall or curved curb.
● The area directly under the bumpers is not detected.
● If obstacles draw too close to the sensor.
● The bumper or sensor receives a strong impact.
● A non-genuine Toyota suspension (lowered suspension etc.) is in stalled.
● There is another vehicle equipped with parking assist sensors i n the vicin-
ity.
● Towing eyelets are installed.
● A backlit license plate is installed.
In addition to the examples above, depending on the shape and c ondition of
obstacles,  detection  may  not  be  possible,  or  the  detection  rang e  may  be
shortened.

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’év iter les irrita-
tions cutanées.
