Caution regarding interference with electronic devices

●

People with implantable cardiac pacemakers, cardiac resynchronization
therapy-pacemakers or implantable cardioverter defibrillators should keep

The radio waves may affect the operation of such devices. If necessary,
the entry function can be disabled. Ask your Toyota dealer for details, such
as the frequency of radio waves and timing of the emitted radio waves.
Then, consult your doctor to see if you should disable the entry function.

●

Users of any electrical medical device other than implantable cardiac
pacemakers, cardiac resynchronization therapy-pacemakers or implant-
able cardioverter defibrillators should consult the manufacturer of the
device for information about its operation under the influence of radio
waves.
Radio waves could have unexpected effects on the operation of such
medical devices.

Ask your Toyota dealer for details on disabling the entry function.

■

When adjusting the seat
Take care when adjusting the seat so that the head restraint does not touch
the ceiling.

WARNING

■

When adjusting the seat position

●

Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.

●

Do not put your hands under the seat or near the moving parts to avoid
injury.
Fingers or hands may become jammed in the seat mechanism.

■

Seat adjustment

●

To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.

●

Manual seats: After adjusting the seat, make sure that the seat is locked in
position.
