Dealer Service Manager where I bought mine said Stop, put in neutral, apply parking brake and then put into Park. It was mainly advice against driving off when the Parking Brake was on as it caused problems.Quote:

Just a quick question - how do you drive off in Park?
I try and rotate knob (sort of) slowly - click, click click - hoping this will prolong its life, a bit!
Before our last trip I removed the centre section and familiarised with the 'pull cord' - bit of a worry!
Sorry, I mistyped that. Meant it to say with the Parking Brake on (I've edited the original post accordingly). Simply push the accelerator and it will release the EPB (parking brake) automatically. Not recommended though. Apparently puts a lot of strain on the EPB. BTW, in case you did not know the EPB lever can be used to activate an emergency stop. Try it somewhere safe. Pull it up and hold it up until stopped. You do not need to apply the footbrake. Makes a lot of noise and when the car gets down to almost stopped, apples the parking brake and turns the engine off I think. Will also activate hazard lights. It uses the terrain response system etc, you're not actually using the parking brake to stop.Quote:

Holding your foot on the brake pedal while in neutral or park for more than the couple of seconds necessary to get out of neutral or park can overheat the selector pcb's 1 ohm resistor that is fitted to monitor the voltage drop of the shift lock motor power. When the resistor overheats its solder melts which can become a cold solder joint or the resistor can lift off its contact patch totally. The resistors are tiny so can overheat quite quickly. Stopped at traffic lights with the gearbox in neutral and foot on the brake pedal is asking for trouble.
I though it also applied the handbrake (ie shoes inside the rear drums) at the same time (rather than when the car slowed down) - just in case there there was a total hydraulic brake failure (rare but could happen).Quote:

Yeah found that out the hard way in D4 number 2, which is a MY13.5, when I got a flat battery at a servo.Quote:

Of course, it wasn't hard to work out, as I already knew where to look.
My 2016 Merc won't even tell you where the battery is ... manual just says to refer to dealer. [bighmmm]
The handbrake/parkbrake will be used at speed only if using the ABS pump doesn't slow the vehicle.Quote:
