Some time ago I recall one an uncle telling me that I could engage a chirp and courtesy flash on the factory Jag alarm on my s-type as opposed to the no chirp with courtesy flash. I was wondering if anyones ever heard of this or something similar?

 

Try pressing the lock button on the fob 2x's. On my '03 that is how I get the horn chirp. One push just gives visual confirmation with a flash of lights but no audible noise.

I like this feature because there are plenty of times I do not want a confirmation sound when I lock.

 

I've read somewhere that if you press the lock button twice within 3 seconds it puts the car into sleep-mode and reduces the drain on the battery.

 

Haven't done this with an S-Type, but with the XJ it can only be programmed with the dealer level diagnostic system (IDS/SDD).

 

I've never seen any documentation to support this theory.

 

I think you'll find 2 pushes tells it to deadlock and enable the ultrasonic alarm sensors and yes puts it straight into at least part of sleep. You'll see it turns off any lights that were on, for example.

IDS/SDD can do various tweaks if you really care. Just pay for what you want, I suppose.

 

Theory Would Imply I'm Assuming. You Learn Something New Everyday.

 

So true, especially with these cars.

 

John, I don't believe US Spec cars have deadlocking. (Having said that, I don't really know what deadlock is....just read in "Non-US Spec cars only" next to it in the manual. (Or maybe it was "UK-Spec cars only?")

 

Oh. Idea is that 2 rapid clicks disable the internal door handles (and unlock button) so any would-be thief can't open any door even if they break door glass. Also can't turn off/bypass the alarm without using a key (or its fob).

It means there's little point breaking in with the hope of driving the car away.

Easy to test: double lock as mentioned (parked, engine off, key out) while still in the car, then try to open door using the door's lever. Over here, door stays locked. Alarm likely to go off. Key in ignition will make it happy again.

 

Either way, I believe changing the settings cannot be done without the correct tools.

 

Interesting idea but, alas, neither my USA '01 nor '03 S-Type behaved as you described after activating the security button. Here's what I learned regarding the security systems in my '01 and '03 US-based S-Types. Some of these features may be dealer-programmable so I can't draw any sweeping conclusions...

For both MYs -
- the security system activates 20 seconds after the security button has been pressed.
- 1 tap of the security button activates security and extinguishes interior and exterior lighting.
- 2 taps in quick succession does as above and also gives an audible chirp from the car's horn.
- activating the security system does not disable the interior lock levers & door handles, even after the 20 second delay; however, opening the doors after the 20-second delay will sound the alarm. If you open the door in less than 20 seconds - no alarm.
- with security activated, moving the interior lock lever to unlock position does not trigger the alarm; pulling the door handle DOES trigger the alarm.

And here's where the cars behaved differently:
- on the '03, simply inserting the key in the ignition shuts off the beeping horn alarm as JagV8 described above; however, this did not work on the '01, which required that I insert the key and turn it to Pos I.

 

How odd. The deadlocking feature (activated on 2 quick taps) is handy. I wonder why it's not used on all cars. I've not had a car without it for many years.

 

My guess is there is some U.S. federal mandate prohibiting deadlocking / immobilizing door handles.

 

Could be. Laws vary a lot.

 

Hi
I had never known about the deadbold system if I hadn't read about it here.
Tested it on my year 2000 S Type and works.

press the lock button twice within 3 seconds and it"s in deadlock. the doors can't be opened even from inside.

 

Excellent.

I was starting to think it was UK only!

 

Probably ever since whichever politician it was dumped his car into the river and his mistress drowned.

Another variant on "think of the children".

 

You'd think everything (*) would be banned...

(*) even guns? noooooo

 

Goes to show how stupid people(politicians) can be,

Which one is most possible to happen:

a child opening the door from inside and running on to the street.
something happening to the car with kids in it.
the drowning mistress.

I think it's a great security option.
