SCARY Cruise Control Issue!
Just recently took delivery of our CPO 2008 C300 Sport and had a nerve rattling experience yesterday. My wife was driving the car home from the dealer (her first time at the wheel) and was reaching for the turn-signal stalk to signal a left at a sweeping Y intersection. Vehicle speed was about 25-30 MPH. She inadvertantly pulled on the cruise control stalk, and the cruise control engaged and started to accelerate! It was trying to return to whatever the previous speed setting was (as it should). Fortunately, she's a good driver and immediately tapped the brakes, which killed the cruise control - but not until some disturbing acceleration took place. I have to admit, I have touched the cruise control stalk by mistake when reaching for the turn signal stalk - guess I got lucky.
Anybody else experience this? Seems like a really poor design, (stalks too close together) especially for Mercedes, who have a reputation for safety!?

This has happened to many, takes getting used to. I never use the cruise control, but my sons have used it and say it is far easier to use in real life than the ones in their BMW 3 series. Its just the Merc way of doing things.

I agree. I always hit the cruise control when trying to hit the turn signal
Poor design I agree
IDK why they don't just make a button on the bottom of the steering wheel. Like the 07-08 TL-S. I believe they have the best interior

Coming from toyota/lexus products, it did take me a while to adjust. however, even if you mistook the CC stalk, you would be pushing it down or up anyways, which doesnt activate CC. You have to pull the level towards you in order to have it re accelerate to previous speed.

this happened to me when i first got the car too, but now that i'm used to where it is, it never happens anymore. in fact i use cruise control all the time now.

Poor design, they should have put the cruise control somewhere else. but for me, I never use the cruise control. it promotes me to not pay as much attention on the road and it makes me more of a road hazard since I'm half driving and half dozing off..

Just because a design is not what you are accustomed to does not automatically make it a poor design.
Once I became accustomed to the layout, it works as an ergonomically sound setup. Of course, when I jump into the Audi, there is usually a little "finger searching" until I get my "motor memory" readjusted.

I agree, as frustrating and frightening as this must have been for the OP and his wife. There is an accommodation period, but having reviewed a variety of speed control switches as an automotive product planner, there is much to recommend the MB approach. But, familiarity is required. I note you said this was her first time driving the car. Had she reviewed the owner's manual, or had a controls location briefing from a knowledgeable driver beforehand? If she was simply given the keys on the premise that cars are fungible, the risk of this and other errors is certainly enhanced. With experience, the OP and his wife will likely find that this control is intuitive and finger-tip easy, without the visual challenge of the Toyota-originated style small stalks under the 4 o'clock position on the steering wheel rim.

Poor design with a dash of arrogance, since I understand that it's always been like that.
Can't see any logical reason to have both stalks on the same side and in the positions they're in. I'm surprised that it hasn't been raised as a safety issue and a contributing factor in accidents.
The cruise control is in the most accessible position for me to reach, based on how I hold the steering wheel. Unfortunately I use the turn signal a hell of a lot more then the cruise control, resulting in frequent accidental cruise control activations.

The design is correct. The turn signal stalk is perfectly placed at 9 o'clock. I think most people are using the old style ten and two rather than the proper nine and three hand position.

As someone stated before doesn't the cruise control only activate once you pull it towards you rather than up or down? If so, i don't see how the problem could arise.

Umm most Mercedes-Benz have it there so its not poor design but poor driving. Even my 1990 190e has it there and I've never pulled either when signaling. Just different then most jdm/american cars. Takes time to adapt.

I have had my CC set to 75 or something, then brake to about 30 to pass an electronic toll. By reactivating the CC so that it accelerates automatically to 75 is slow I like said up until 45mph

Also keep in mind if the car was on cruise control and you were going up on an " incline " the car will rev / speed up to maintain the speed indicated.

Mercedes-Benz is not perfect. They have their own flaws too. The cruise control stalk placement is just downright stupid and unnecessary. Why not have it on the steering wheel?

2) A behind-rim mini-stalk (a la Toyota and many other Asian brands) must be located below the 9 and 3 o'clock positions so as not to interfere with steering rim access. This means having to move your head to look down, with repeated unnecessary distraction.
3) Due to the multiple functions of a single cruise control switch (more complex than the switches now on the wheel face spoke) the labels should be visible. A lower steering wheel location requires more of a change in focal length for the eye. The stalk position requires the lens of the eye to undergo less change for each refocusing. This also requires less time with eyes off the road and less head movement to look down toward the lap.
The OP informed us that his wife knew the location of the stalk, but somehow touched the wrong stalk and moved it, unlike the up and down of a turn signal, toward her. It is unlikely that, with even minimal attention, she will repeat her first time error.
