4RUNNER_U
■Operation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors
have been locked/unlocked. (Locked: once; Unlocked: twice)
■ When the door cannot be locked by the lock sensor on the upper part
of the door handle
■ Alarms and warning indicators
A combination of exterior and interior alarms as well as warning lights is
used to prevent theft of the vehicle and accidents resulting from erroneous
operation.
When any warning lights come on, take appropriate measures depending on
which warning light comes on. ( P. 565)
Touch both lock sensors on the upper and
lower part of the door handle simulta-
neously.

CAUTION
■Wearing a seat belt
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failure to do so may cause death or serious injury.
● Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
● Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat more than
necessary. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
■ 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.
■ 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. 80)
