My car has a shadow, in the centre dial (with the speedo, and message centre) of an adaptive cruise marker. Was this car ever fitted with ACC? The light doesn't come on during startup, but I can see the outline in some light. However, you can't see the outline of it in photos. Here is where it would be, outlined in red:

Anyone else notice this? Were some of our cars fitted with ACC?

 

I did alot of PDIs in 2003 and never saw an X308 with Adaptive cruise. The first I saw was a fully loaded X350 Supercharged 2004MY. The US market usually gets new features a Model Year later than the ROW.

Im also curious about this. I saw the same thing 2 weeks back. The dash may have been used on another model that had ACC for the same year?

 

The XKR had adaptive cruise control, and it used the same instrument cluster as the X308, hence the light. I wondered the same thing a few years ago. The X308 never had ACC though.

 

Burmaz is correct, I posted about this last year sometime if I remember. I don't quite understand why they didn't offer this feature on the XJ when it is the top of the range vehicle. In the last few years Mercedes have been making a shout about having this system on their new cars but Jaguar were doing it way back when. But then again Jaguars are all about being subtle and classy, not loud and brash.

What I have wondered is if it could be retrofitted seeing as the framework is there...

 

Yes!! I would be interested in having ACC... but I don't know if an aftermarket setup is all that trustworthy.

Sat Nav, touch-screen, would be nice on my car as well... but the aftermarket units look crap

 

I didn't mean an aftermarket kit I meant using the XK system seeing as they are same engines and different bodies. I wondered about obtaining the system particulars from a scrap XK8/R and fitting them on the XJ.

Sorry, aftermarket isn't the right term. I meant an ACC system put in after maufacture of our car, idk the term for that. Retrofit? Anyway, an XK8 system would be so cool in our car! I think someone should try this, its actually a very cool idea... but I would not trust a system I installed myself. lol.

 

I wouldn't want it on my car anyway. Because if I'm totally honest with you, I know when I'm too close the car in front. I don't need a computer to work this obvious event out for me. Normal Cruise control is enough for me

 

Haha agreed. I loved the newer TG episode (new XJ test, race against God) where Jeremy shows the Jaguar's ACC: "Heres the safe following distance... and here we go right down to the FULL AUDI."

I don't know, I've never used ACC, but I like the idea of it relatively well. It seems like on a long road journey (like in the US, 1000miles) it would alleviate some of the work of driving on the highway.

 

I don't remember when the XK got the ACC but the 2003 XK IS NOT THE SAME AS THE X308. The 2003 XK is the 4.2 and it is a different car from the 2003 4.0 XJ sedan. Retrofit may not be an option.

The Adaptive Cruise was engineered with the new engine management system for the 4.2L engine, it's basically integral. It's just too expensive to add it to the car/system that was going away in after 2003.

Cheers,

 

That is a fair enough explanation, but if it was developed for after 2003, then why was the light fitted to 98-03 cars? It was on the XK8/R before then anyway I'm fairly sure because I remember seeing an advert for it or a brochure feature on it.

 

Ya know! You caught me there! Old age creepin' up. The more I think about it, there were some very rare XK8/XKR models with the adaptive cruise. What made me recall that is I once had a prototype X202 in the shop that was a Delphi development mule for the later 2nd generation adaptive cruise. We had to hunt down a 2001 XKR with ACC to swap some parts with. So that does explain the telltail in the instruments at that early date. But the XJ explanation still holds, it went away in 2003, the XK still had 3 more years beyond that, on top of the new engine and engine management.

1000 pardons!

 

By some bizarre quirk of fate, I just ran across this tidbit this morning while researching another matter, it is from the 2001 MY Technical Update:


Cheers,

 

I LOVE ACC! The 05 XJR has it, and it is a very impressive system. It will even slam on the brakes if the person in front of you decides to stop suddenly. It will go as low as 20mph or so before it disengages too. It takes some work out of long trips too. Slow trucker, the car matches the speed, change lanes, and the car will accelerate at a reasonable rate back to it's set speed. That would be awesome if it could be integrated into the x308 models!

 

I would be careful about advertising the braking so much. I only say that because not all cars with ACC have an equivalent braking capability. Yours does really well in that department, the earlier versions and some other makes don't do quite as well. Our current cars will literally bring a car to a virtual stop, but that's safety, not a feature. I don't want to encourage folks to rely too much on that capability.

My two cents...........

 

I know for a fact that you could get it in an 01 XKR because I have driven one

 

My 2001 Sovereign LWB has never had its dasboard binacle changed. But strangely, it also has a symbol (unlit) for adaptive cruise control

 

IDS asks for acc with x308. But that doesn't say anything yet.
