Can the Speedtronic function be used to limit a valet drivers speed when driving my car?

I'm wondering if I can set the max speed to 35mph (or anything) when I have a valet park my car by using the speedtronic function?

Any tips?

Speedtronic

Speedtronic brakes automatically so that you do not exceed the set speed.

variable for speed limits, e.g. in built-up areas more

• Permanent for long-term speed restrictions, e.g. when driving with winter tyres fitted more

Variable Speedtronic
You can operate cruise control and variable Speedtronic with the cruise control lever.

• LIM indicator lamp off:
  Cruise control is selected
• LIM indicator lamp lit:
  Variable Speedtronic is selected

You can use the cruise control lever to restrict the speed to any speed above 30 km/h while the engine is running.

LIM indicator lamp
Selecting variable Speedtronic
Check whether LIM indicator lamp is on.
If it is on, variable Speedtronic is already selected.
If it is not, press the cruise control lever in the direction of arrow .
LIM indicator lamp in the cruise control lever lights up. Variable Speedtronic is selected.

You can only exceed the limit speed stored if you deactivate variable Speedtronic:

• using the cruise control lever
• if you depress the accelerator pedal beyond the pressure point (kickdown)

It is not possible to deactivate variable Speedtronic by braking.

Storing the current speed
You can use the cruise control lever to restrict the speed to any speed above 30 km/h while the engine is running.
Press the cruise control lever briefly up or down .
The current speed is stored. You will see the stored speed in the multi-function display.

Selecting a stored speed
Briefly pull the cruise control lever towards you .

Making adjustments in 10 km/h increments
Briefly press the cruise control lever up for a higher speed or down for a lower speed.
or Keep the cruise control lever pressed until the desired speed is set. Press the cruise control lever up for a higher speed or down for a lower speed.

Making fine adjustments in 1 km/h increments
For a higher speed: pull the cruise control lever briefly towards you .
or Keep the cruise control lever pulled towards you until the desired speed is set.

Deactivating variable Speedtronic
There are several ways to deactivate variable Speedtronic:
Briefly press the cruise control lever forwards .

or
Briefly press the cruise control lever in the direction of arrow .
LIM indicator lamp in the cruise control lever goes out. Variable Speedtronic is deactivated.
Cruise control is selected.

Variable Speedtronic is automatically deactivated if you depress the accelerator pedal beyond the pressure point (kickdown) and your current speed does not differ by more than 20 km/h from the stored speed. You will hear a warning tone if this is the case.

Permanent Speedtronic
You can use the on-board computer to limit the speed permanently to a value between 160 km/h (e.g. for driving with winter tyres) and the maximum speed.
Shortly before the stored speed is reached, it is displayed in the multi-function display.
You cannot exceed the stored limit speed, even if you depress the accelerator pedal beyond the pressure point (kickdown).
Setting permanent Speedtronic
Press or to select the Settings menu more.
Press to call up the selection of submenus.
Press or to select the Vehicle submenu.
Press to select Speed limit (winter tyres) .



Press the or button to select the desired setting.
The following settings can be selected:

• Off
  Permanent Speedtronic is deactivated.
• Select a limit speed between 240 km/h and160 km/h in increments of ten.

To select a different display, press , or .

Speedtronic permanent limits don't apply to all the AMG's unfortunately and the variable limits are reset with the ignition but you could use it to limit the speed so long as the engine is not stopped and the dude does not know how to deactivate it.

So how can I determine if it is on My AMG? I would think when I drop off my car for valet that they would keep it running. It's when I retrieve the car that it wouldn't be working unless the permanent limit was set.

Is there something I can do to check to see if I am able to set permanent limits on my AMG? I haven't seen the winter tire screen on my model.

Thanks,

Michael

Basically mate just follow the instructions for setting permanent speedtronic in the pic you posted.

If you can't see the menu then the function is not available.

I'll check next time I take her for a drive. I'm glad I found the info. I never knew there was a Speedtronic that was different from cruise control. I just saw the LIM light and didn't know what it was.

If anyone else in the US wants to try and post results that would be great as well since my car is sleeping in the corner of my garage until the snow melts.

Mine is a US spec manual and doesn't have a speed limiter. This came up when I became curious about that pressure point you feel when you step on the accelerator. AFAIK, this is the override for the speed limiter, which when you think about it makes sense as a safety feature for when you need to escape from a danger zone with the limiter engaged. It appears that in my car, the override is just a useless remnant that MB didn't bother stripping together with the limiter.

I thought all cars in the US, even those with auto tranny, don't have the limiter (I assume because of liability concerns), but I may be wrong. Either way, because of the override, I don't believe this feature would be suitable for preventing the valet parking guy from messing with your car. It's really meant to help you reduce your contingent of speeding tickets.

Thats partially true, the detent is an over-ride but its also kickdown so in an auto tranny its functional.

Also the permanent speedtronic cannot be bypassed only the variable system can be.

Thanks for pointing this out. However, I was careful enough to call it a useless remnant in my car (since it's a manual).

Do you mean that 155mph limiter? Well yes, but I don't think it's likely the valet parking guy would consider this one as a real impediment for his joy ride. Well, unless he's a real bad ass of a valet parking guy.

You said its the override for the speed limiter, i said thats partly true permanent speedtronic cannot be overridden.

That is not the same as the max speed limiter.

Read the blurb posted by nmslk.
