Failure to do so may result in death or serious injury.
■When towing the vehicle

*: 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. 438)
■ 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.
