Event data recorder
Your vehicle has computers that monitor and control certain aspects of your
vehicle. These computers assist in driving and maintaining optimal vehicle
performance.
Besides storing data useful for troubleshooting, there is an event data
recorder (EDR) that records data in a crash or near crash event.
The SRS airbag sensor assembly contains the EDR. In a crash or near crash
event, this device may record the following information:
• Engine speed
• Whether the brake pedal was depressed or not
• Vehicle speed
• To what extent the accelerator pedal was depressed
• The transaxle shift position
• Whether the driver and front passenger wore seat belts or not
• Driver’s seat position
• SRS airbag deployment data
• SRS airbag system diagnostic data
• Front passenger’s occupant classification
The information above is intended to be used for the purpose of improving
vehicle safety performance. Unlike general data recorders, the EDR does
not record sound data such as conversation between passengers.

■Note for locking the doors
● Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
● When the lock operation is performed using the lock sensor, recognition
signals will be shown up to two consecutive times. After this, no recogni-
tion signals will be given.
● If the door handle becomes wet while the electronic key is within the
effective range, the door may lock and unlock repeatedly. Place the key
in a position 6 ft. (2 m) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information
display and a buzzer will sound outside the vehicle. To turn off the alarm,
lock all the doors.
● The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again, or
use the lock sensor on the lower part of the door handle.
● Fingernails may scrape against the door during operation of the door
handle. Be careful not to injure fingernails or damage the surface of the
door.

Sliding door
■ To prevent damage to your vehicle
● Vehicles with the power sliding door:
• Do not apply excessive force when the sliding door is operating.
• Do not place your hand or foot near door hinges or rollers when the
sliding door is operating.
• Avoid forcibly opening the left side sliding door fully when the fuel filler door is opened. Otherwise, the fuel filler door may be damaged.
• Take care not to damage the sensors (installed on the front edge of the power sliding door) with a knife or other sharp object.
● Make sure there is nothing in the doorway before closing.
● Do not close the sliding door by applying the brakes. Doing so could cause
the sliding door to be damaged.
Make sure magazines are not bent or
protruding from the sliding door pockets.
Do not insert anything too big so that the
shape of the sliding door pockets is dis-
torted. Such objects may obstruct the
opening/closing of the sliding doors, dam-
age the sliding door pockets or the vehi-
cle body, and may result in a malfunction.

CAUTION
■
Jam protection function (vehicles with power back door)
Observe the following precautions.
Failure to do so may cause death or serious injury.
● Although the back door stops closing when the jam protection function
detects an object, take extra care as you may still be injured if part of your
body is already caught.
● Never use any part of your body to intentionally activate the jam protection
function.
● The jam protection function may not work if something gets caught just
before the back door fully closes. Be careful not to catch fingers or any-
thing else.
● The jam protection function may not work depending on the shape of the
object that is caught. Be careful not to catch fingers or anything else.
NOTICE
■To prevent damage to the power back door
● Make sure that there is no ice between the back door and frame that
would prevent movement of the back door. Operating the power back door
when excessive load is present on the back door may cause a malfunc-
tion.
● Do not apply excessive force to the back door while the power back door
is operating.
● Take care not to damage the sensors (installed on the right and left edges
of the power back door) with a knife or other sharp object. If the sensor is
disconnected, the power back door will not operate in automatic operation.

CAUTION
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
■ Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. ( P. 129)
■ Seat belt pretensioners
● 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 seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
