Can the seatbelt warning chime be de-activated?

There is no dinger as the other guy suggests . sound comes from the driver door speaker .
The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings through the left front speaker. The radio receives audible warning requests via the class 2 serial data line. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. On vehicles with an audio amplifier, the amplifier instead of the radio generates the audible warnings and receives audible warnings requests via the class 2 serial data line. Either the radio or the audio amplifier is the chime producer. The following lists the audible warning priority and the pulse rate:
Fast rate chime (150 pulses per min)
Medium rate chime (100 pulses per min)
Slow rate chime (50 pulses per min)
Turn signal reminder (will pulse at turn signal flasher rate)

Your best bet ,wear your seatbelt . so the sound goes off . If you do wear the seat belt and the chime sounds ,have a qualified repair shop check it .

What make , model an year vehicle ? Most vehicles will chime for a number of reasons , just depends on year , make ,model etc.....

You turn off the seatbelt warning via a recode of the instrument cluster u cam use vag com software, or take to the dealer

may happen when the system senses some weight on the passenger seat (dog, etc) or the weight switch is faulty/stuck. You can verify if this is the reason if the passenger airbag notice light shows ON.

This is the seatbelt indicator, its not seeing that your seatbelt is fastened ifthe light stays on and the chime keeps going off.

There is a switch inthe seatbelt that closes when the seatbelt is buckled, and if not, thelight stays on and the chime goes off.

There are a couple reasons thiscould happen. It could be a wiring issue going to the seatbelt buckle,or more likely the buckle itself. Your truck is pretty new, so if youare under 36,000 miles the repair would normally be covered underwarranty.

Also, I suggest check the Repair Manual for Jeep-WK-Grand-Cherokee-Section-08O-Restraints (page 473 and next, for Seat Belt)

Hope helps with this (remember rated this) Good luck.

Get in the car, make sure your dome light is set to door-operation.
Close all the doors, does the dome light go out?
If so, it's not the door ajar chime. If not, one of your door pin switches is defective.
Buckle your seatbelt, does the seatbelt warning light on the dash go out?
If so, it's not the seatbelt alarm. If not, it's the seatbelt buckle receiver.
The light warning works with the key off, so it is not that since turning the car off would not stop it.
Last thing it could be is the ignition key alarm.
I have seen a few malfunction over the years.

Section 13-09: Gauges, Warning Devices — Chime System 1996 Windstar Workshop Manual
DESCRIPTION AND OPERATION Warning Chime Systems Three distinct sounds are used to indicate the area of concern. Seat belt warning generates 1 chime per second
key-in-ignition generates 2 chimes per second
headlight on generates 4 chimes per second.
Key-In-Ignition Warning The key-in-ignition warning will sound when the driver's front door (20125) is opened with the key in the ignition switch. It will continue to sound until the key is removed, the front door is closed, the ignition switch is turned to START or the vehicle speed is over 24 kmh (15 mph).

Safety Belt Warning When the ignition switch is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.

• The safety belt warning indicator lamp (10C859) will activate for 60 seconds or until the driver's safety belt is fastened. Both the chime and lamp activate at the same time.

Anytime the ignition switch is released from START and returns to RUN while the safety belt lamp or chime is activated, the safety belt warning lamp or chime will remain activated until either the timing sequence has been executed, or the safety belt is buckled.

Headlamp Switch On Warning The chime will be activated if the headlamps or parking lamps are ON, the key is not in the ignition and the driver's door is opened. The chime will sound at a rate of four per second.
