Side mirrors tilt down when reverse

[wheelslover]

Hi 

Is this a default feature or is not present in W246 model?  When reverse, the side mirrors (both driver and passenger side) dont tilt down.  I saw some writing on this in other forum, but was not working for me.

 

thanks

only the passenger side shud dip down.

 

engage reverse gear, press button to adjust left mirror, subsequently when u engage reverse, the mirror will dip down.

 

if it doesnt, mean yours dont have this feature

Hi wheelslover

 

I think you might. the earlier post is missing a couple of steps.

Its the same procedure for mercs from as early as 2005

 

a)  Push button to activate adjustment of left mirror on the driver door (red led on...) and Set transmission to reverse.

 

your b class would tell you that left mirror is selected for adjustment by lighting up a red LED on the button.

while in Reverse gear and this red LED on, use the circular 4 way button and adjust the mirror to the position you want it to 

tilt to. I.e. next time you select reverse, the mirror will move to this position. 

 

c) once you like what you see (like the left road curb), press and hold the left mirror activate adjustment for like 10 secs. 

this is believably to store the tilt mirror position. [not sure if your really need this step but it worked for my 2015 b180]

 

d) now set transmission to D and the mirror should tilt back in the next 15 secs. (not immediately) you can drive off first and check later.

the reason why it will take 15 secs is because it assume you still be parking and might go into reverse in the next few seconds so better don't tilt back

up first so as not to keep going up and down.

 

e) Every time you want the mirror to tilt down in Reverse gear, make sure the left adjustment button is "on" {ie red LED lighted]

 

This feature usually comes with the memory package so even if it doesn't work, you can just use the seat memory recall to move the mirrors back in position.  Only problem is you have to manually tilt it every time you get into reverse. My wife does that all the time when sometimes merc electronics get iffy and not return to original position.

 

Yes...You may not need it all the time especially like you mention the reverse cam but the cam doesn't indicate the left side curb very well. I use it to avoid scratching my brand new rims against the curbs or creating knock blisters on the tires.

 

hope this works out for you...

 

your sales exec did not set it for you when you collected?

Thanks you so much. Yes , it works perfectly for me after following your instructions. I cant recalled if MB show me this feature, but sure it wasn't set for me.

My mirrors started acting up after the warranty ended.  Sometimes it doesn't go back to the original position after tilting down in reverse gear.

On a few occasions, it worked after I sprayed lubricating oil liberally.  I think perhaps this should be a regular maintenance thing to do?  Spray WD40 behind the glass?

Pearljam, ..the motor needs some 'stretching exercise'. Try moving (via the control ) the mirror to the max in all 4 (North/SOUTH/ E/W) directions, then press the memory button to return , and now try the reverse gear.

Need to repeat this a few times over couple of days...

Pearljam,

 

Unfortunately they do act up. I have had 2 mercs and they acted up on me.

sometimes its not the mechanism fault. for example, some one knock your mirror out of place and 

the mechanism lost its alignment and like doesn't what position it is in.

 

I would do the "Stretching" exercise Jtang recommended to get the mechanisms back in sync.
