Assuming that every new Toyota includes such a disclaimer statement.  
Wouldn't it be fun to go to a Toyota dealer, negotiate a price, and then
say..."Oh, is it true that I your winer's manuals all say.....require
permission from Toyota to ensure the warranty...before installing any
transmitter..."  Now the salesdroid would have to check it out,
but even if they said no, I'd ask to see a manual and then say, no
I can't risk buying a Toyota necause even if you approve the transmitter
I own now, I don't want to be forced to get your approval just to install
a different transmitter in 6 months from now.

If Toyota salesman hear some of that, the pressure can become pretty
intense on the factory.

Anyoine know if there are any other such manufacturer's stipulations
against transmitters in their vehicle product line.  This might be a
good "consumer report" item that ARRL should write-up for a future QST
issue.

It's a violation of federal regulations, OSHA? BATF?, one of those, to
transmit within 500 feet of a wired explosive charge. Since airbags are
deployed by a wired explosive charge, lead azide, it would seem that you
can't legally transmit on an amateur radio in an airbag equipped car.

If that is totally true, then any and all mobile operation must now
be verboten because you never know if the other vehicle within 500
feet of you is equiped with an air bag.  Likewise, my property is
only 200 feet deep.  Even if I had my antenna at the very rear of
my yard I'd be withing much less than 500 feet of the road and
could not with any assurance know that there isn't an air-bag equipped
vehicle within 500 feet of my antenna (heck, my neighbor's car in the
driveway may have an airbag).

I think there must be some clarification on this as the motor
vehicle manufacturers and/or the sellers of radio
equipment are obviously in exact opposite possitions as to
the viability, use, etc. of their respective products.

By the way, if amateur's can't transmit with 500 feet of an air-bag
equipped vehicle, neither should anyone else (eg. police, fire,
rescue, commercial mobile & base).  Then too, what about all those
broadcast antennas that are easily with 500 feet or less of some
road?

I'll hazard an assumption here that there is some type of exception
with regard to the application of the 500 foot transmit prohibition
and the type of "charge" used to deploy air-bags.  If there isn't, and a
strict reading of the rules is applicable to this situation then there's
a lot more at stack here than just ham transmissions.

Anyone with any more details out there?

And even if you were willing to take the risk of buying the Toyota,
you could use this a a bargaining point, or do this at the dealers
where you're not going to buy the vehicle, make your point, and still
get a Toyota.

Bill, I recently went in to a GEO dealer, picked out the car of my dreams, negotiated the price, then finally inquired about stipultions in the warranty regarding transmitting equipment.  The salesperson said that there was nothing specific about it in the warranty, but if I install transmitting  equipment which causes a problem with the car, the warranty coverage will end there.
So did our negotiations :-)

To a certain extent I see less problem with the GEO dealer's statement than
the Toyota approach.  It would be difficult at best for a GEO dealership
to "prove" the transmitter was the cause of the problem.  In any case,
I'd have likely done what you did...walk out and tell'em to stuff their
sale, I'll buy from a manufacturer who will stand behind their product
in terms of the vehicle being resistant to mobile radio RF fields.

I have a friend in the industry, I'm going to ask him about the subject
and see if he knows of any minimum standards that a vehicle must/should
be capable of withstanding relative to exposure to RF, regardless of the
source (eg. Ham, Police, Cellular, etc.)  Anything I learn I'll post
as a follow-up.

It wouldn't be the first time that regulations from one department
were in direct contradiction to those of another. As an example,
the company where I work had a custom made wheelchair lift constructed
for a stairwell to come into compliance with the Federal handicap
access regulations. When they went to get a permit to install it,
they found that it was forbidden by the fire code to install such
a device in a stairwell that could be used as an emergency exit. So
one regulation said that they *must* install the device, and another
regulation *forbade* it's installation. Meanwhile they were stuck
with a $30,000 lift and the prospect of fines. Figuring that the
Federal government was bigger than the city building inspection
department, they installed the lift anyway and are fighting the
city in court.

 Toyota (like General Motors) sells enough cars that even if EVERY amateur
 quit buying thier new cars, they wouldn't notice. (Or care) There is enough
 of a market out there without the amateur community. The only manufactures
 that HAMs have any clout with are those that depend on them for a major part
 of thier business. Sad but true, we are NOT the center of the universe.

While I agree with the fact that hams may not be the center of the universe (although not all of the data is in on that one yet ;-), the amateur community is not the only entity which uses transmitters in vehicles.  I think that emergency/government/etc services was mentioned before by others.  Also, what if we added all the folks who use CB's in their cars to the list?  By casual observation, I see LOTS of vehicles during the daily commute with transmitters of one type or another installed.  The caveats p

ut forth by the auto makers do not specifically single out hams with respect to transmitter/transciever installation. I think that the community of 'mobile-radio-users-in-general' is enough that it ought to get SOMEBODY's attention (we can only hope).

I have discussed the problems with one of the principals in setting the
ASAE, ASE, and hopefully the ISO standards for networking of computers
used on offroad and farm machinery about the problems of interference
btween the computers and radios. He was of the opinion that any computer
that caused radio interference or any computer network that couldn't
exist in a 100 watt envornment was broken.

about these exploding airbags.  Just imagine what fun some ham who lived
near an interstate and who had a full boat EME rig capable of a
couple MW ERP could have by aiming toward a traffic lane.  

Yet another highway participatory sport - Trolling for Airbags.

Hmm, better get to work on a set of rules.  What bonus points should I
award to launching a yard ape out the passenger side window?  Is that
worth more or less than launching Rover?  Should there be a Yup-mobile
bonus for scoring a BMW or Benz or jap clone?  Questions, questions...

Post by Brian Cuth » Sat, 26 Dec 1992 01:49:39

This whole issue seems unbelievable to me.  Does anyone think that people
ask Toyota before installing a cellular phone ?

I'm not a lawyer, but I would bet that unless they come right out and say,
"You can't put transmitters [read cellular phones] in this car" they
would violate some "suitablilty for the intended purpose" statute or some
such.  Virtually everyone who buys a car today is at least thinking about
putting a cell phone in it.

Furthermore, I agree with someone else's comments regarding the person
sitting next to you at the traffic light.  What's supposed to happen
when he keys his 200 watt UHF transmitter ?
