Yes if you hold the button for the outside temp for 3 seconds it too stays on that selection. I once read that all XK100's came with a seat heater installed. Paying for the license to use it added the on / off button. This seat heater one is unproven, just something I once read. After reading that I wondered to myself, wouldn't it be cool if the power outside mirror retraction motors are in all cars too. . . Then I thought about the COGs for 2 of those motors - nah not even worth checking .

Oh yeah - press the radio's on /off button in for 4 seconds, AVC (Automatic Volume Control) comes up in the display. It promises to adjust the volume to keep a comfortable listening level for noisy areas. You can select levels 1 through 5, or off.

Bad news is I couldn't ever get anything that could be called a worthwhile improvement by using it. On one hand any circuitry you put in the chain will IMO degrade the sound; Oh the other hand I really couldn't say: "this setting # is an improvement I can hear" (and I am picky with my sound quality). But it's fun to play around with - see if you can hear a benefit with it.

Boy I sure wish I could find a "secret set up" menu on that radio that would allow me to change the bass / treble cross over point (e.g.: 100hz; 250 hz; 400 hz), or the width of the bass control's boost (e.g.; +/- 1 octave at 150 hz; or +/- 0.5 octave at 150 hz. . ).

Nick, you know the left foot (North america cars) dummy foot pedal is adjustable right? TTYT I never even looked into that one, though others have.. Guess I'm comfortable with whatever it is set too now.

Nick, wow 3rd post, you got me going . After I post one I think of another. Now this one is about the seat heater too. The manual in my 1998 states that the heated seat will get no hotter than the temperature dialed in at your heater's display on the dashboard.

Now this one is funny. I have tested it - sure enough in 15 degree weather with roof down, the seat gets hotter when the heater temp is turned up to 88 degrees than when it is set for say 70 degrees. This I have felt for sure. OTOH, none of the electrical diagrams show any kind of thermostat connected to the seat heater circuit. Somehow the selected temp does impact seat heater, I just wonder how without that thermostat in the circuit. . .

Wouldn't it be fun to find that nearly all of the options are in every car, dormant without the proper switches and software permissions. I always wondered if the wiring for dimmed outside mirrors was there. just need a dimmable outside mirror. I suppose it would turn on each time you pressed the Dim switch on the rear view mirror.

Have we all found the "mirror dip on reverse" feature also mentioned in the driver's manual ?

If not ……………. with the mirror rocker switch set to the passenger side, and with the transmission in reverse, a pull of the toggle switch will lower the passenger side mirror by 7 degrees so you can see the kerb. (a further pull will lower it by a further 7 degrees). When you go out of reverse, it will return to the previously memorised position.

 

In the centre of the passenger dash bolster is a recessed handle. Lift this and it opens a secret compartment.



Inside is the Vehicle Literature Pack, pen holder (amazing the number of XK8/XKR's that have a pen rolling around loose in the door pockets or centre console) and possibly the optional rechargeable flashlight.

When I purchased a three year old 2001 XK8, the Vehicle Literature Pack was still sealed in the original plastic bag in the glove compartment. It had never been opened!

Sorry...just thought I would start a fun thread not based on break downs or car problems

 

don't be sorry !!!!

I wasn't criticizing your posting. It's a great idea, and I'm sure there are numerous tricks that the owners or shop manual don't cover. I just wanted to emphasize that one can learn many features by spending a couple of hours going over the owners manual. I'm sorry to admit that I haven't finished reading my owners manual, and haven't even cracked open the Entertainment and navigational manuals. : 0

I understand this completely. With my previous car (1995 Corvette) there were "secret" sequences of buttons to push on the climate control system that would show various diagnostics and then another trick with a paper clip inserted into the OBD reader socket that would end up showing even more stuff. Always fun finding these type of things. The mirror dip feature is somewhat useful but it would have been better if the mirror dipped automatically just by selecting reverse rather than having to play around with the little toggle.

Nick, Thanks for this one. It was fun to think about.

Only if the only time you back up is when you parallel park. I'd rather be able to see behind my off hand corner, myself.

 

I'm happy with the dipping Mirror, as I can control it one way or the other...Where Jaguar screwed up was not putting Back-up TV in the Dash Screen....Now I have to hit the Dip for the Mirror and look at the clock to see how long it takes to back into someone...…

To check for error codes in the Climate Control System with the internal diagnostics via the ‘Panel Codes’
1. Ignition off - hold down AUTO and RECIRCULATION buttons and
switch on the ignition
2. press AUTO button - if ZERO shows, there's no stored
error codes
3. press FACE button repeatedly to scroll through stored
fault codes
4. press FACE and HEATED REAR WINDOW buttons together to
clear a fault code.
5. repeat step 4 if there's more than one code
6. press FAN button to exit Interrogation Procedure

Control Panel Fault Code Listing

Note Reference fault code #23*: In ambient temperatures below 0°C, this code may be logged because the low ambient causes a temporary low gas pressure. Where the ambient temperature rises above 40°C, with the engine close to overheating, electrical feed to the compressor clutch may be cut and code #23 registered.

0 Normal operation no fault codes present None Wait 30 seconds for system self-check.
11 Motorized in-car aspirator malfunction Harness / connector fault Sensor open / short circuit. Panel fault codes are not stored for motorized in-car aspirator motor failure.
12 Ambient temperature sensor malfunction Harness / connector fault Sensor open / short circuit. After rectification, disconnect the vehicle battery for 10 seconds to reset the system.

Wait, Wait, you recommend reading the manual before you have a major breakdown?

I love the idea that on North American cars the left foot is on the left and by extension in England left feet are on the right.
