128 1-8. Safety information
CAUTION
■SRS airbag precautions
●If breathing becomes difficult after the SRS airbags have deployed, open a
door or 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 or roof side rails.
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment.
● Installation of snow plows, winches, etc. to the front grille (bull bars or\
kan-
garoo bar etc.).
● Modifications to the vehicle’s suspension system.
● Installation of electronic devices such as mobile two-way radios and CD
players.
● Modifications to your vehicle for a person with a physical disability.

When trouble arises

5-2. Steps to take in an emergency
*: Driver's and front passen
ger's seat belt buzzer:
The driver's and front passenger's seat belt buzzer sounds to alert the driver
and front passenger that his or her seat belt is not fastened. Once the engine
switch is turned to the “ON” or “START” position (vehicles without a smart
key system) or the “POWER” switch is turned to ON mode (vehicles with a
smart key system), the buzzer sounds for 6 seconds. If the vehicle reaches a
speed of 12 mph (20 km/h), the buzzer sounds once. If the seat belt is still
unfastened after 30 seconds, the buzzer will sound intermittently for 10 sec-
onds. Then, if the seat belt is still unfastened, the buzzer will sound in a dif-
ferent tone for 20 more seconds.
■ SRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors, side impact sensors, driver's seat belt buckle switch, front passen-
ger occupant classification system (ECU and sensors), “AIR BAG ON” indi-
cator light, “AIR BAG OFF” indicator light, front passenger's seat belt buckle
switch, seat belt pretensioner assemblies, airbags, interconnecting wiring
and power sources. ( P. 432)
■ Front passenger detection sensor, passenger seat belt reminder and
warning buzzer
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and the warning
buzzer to sound even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■ Electric power steering system wa rning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily drops, the electric power st eering system warning light may come on
and the warning buzzer may sound.
