8 Hidden features & tips for your Mercedes E-Class
Let’s dive right into our top eight tips!
1. Deactivate keyless entry using the key
With Mercedes’s keyless access technology, you can unlock and lock your E-Class without taking out your keys.
Simply put your hand behind the door handle to unlock the car!
And to lock, tap on the top of the door handle; it’s that easy!
Keyless access means you no longer have to fumble for keys or look for the unlock button.
However, this isn’t the tip yet!
What if you want to disable this feature for a while?
Well, you can do so with your key!
Get your Mercedes key and press the lock button two times. You will see a red light flicker on the key for a few seconds, meaning that keyless access is now disabled.
To turn it on again, press the unlock button on the key again.
2. Turn on the heated mirrors during winter
Did you know that all Mercedes E-Class side mirrors are heated?
If not, don’t be ashamed because there is no apparent button to turn them on!
Instead, the button that turns on the heated mirrors works together with the rear window heater switch.
This handy feature can help you tackle those frosty mornings in just five to ten minutes by melting away all the ice on your side mirrors so you don’t have to battle visibility.
3. Increase the power output using a RaceChip
While it’s not always needed, having more power in your car is more fun, right?
So, if you are looking for ways to increase the power of your Mercedes E-Class, chip tuning could be the perfect way to bring it to the next level.
And it doesn’t have to be hard to do it – all it takes is plugging a device into the car’s diagnostic link connector.
RaceChip is a great company that develops easy-to-install tuning boxes for Mercedes-Benz and most other manufacturers:
By modifying and optimizing the engine control unit (ECU), the RaceChip can:
- Increase the horsepower and torque of your E-Class by up to 30%
- Give your E-Class up to 20% more MPG
- And it includes a comprehensive engine warranty!
For example, if you have a W213 Mercedes E400 with a 3.0 petrol engine, installing the RaceChip GTS Black will give you an additional 67 hp and 94 lb-ft of torque!
And the great thing is that you can use RaceChip for pretty much every Mercedes E-Class.

4. Check the side of your fuel cap from the driver’s seat
Do you ever find yourself scratching your head, wondering on which side of the car the fuel filler cap is placed?
With a glance at your instrument panel and its convenient arrow indicator, it’s easy to locate.
But now, with plug-in hybrids becoming more prevalent on the roads, there’s an extra detail: an arrow should be present that indicates where the electrical connector is located!

5. Open or close the sunroof using the recirculation button
Imagine you’re zooming down a winding road with your windows and sunroof open and come across some smoke or an echoing tunnel.
Rather than taking your eyes off the road to close all of your windows and sunroof manually, simply hold down the recirculation button!
This will automatically close all windows and sunroof and shut any external air from entering the cabin.
As soon as that situation has passed, hold the recirculation button again to open up the windows and sunroof in the exact position they were before!
6. Let the passenger side mirror pivot down automatically
The next hidden feature is particularly useful when parallel parking your Mercedes E-Class.
Did you know that you can automatically let your passenger side mirror pivot down when in reverse?
This will allow you to see any curbstones and prevent you from damaging your wheels!
You can enable this feature by ensuring your mirror adjuster button is set to the passenger’s side:
So, if you have a left-hand drive car, ensure the mirror adjuster button is set to the right, and your passenger side mirror will automatically pivot down when reversing!
7. Activate the hold feature for the automatic gearbox
If you’re familiar with automatic gearboxes, you will know that the car will start creeping forward when you release the brake pedal.
So, if there’s a time when you have to stand still for an extended time, for example, in a traffic jam or before a traffic light, you have to either hold your foot on the brake or put the car into ‘Park.’
It’s a bit inconvenient, but did you know there’s a third option?
The Mercedes E-Class is equipped with a ‘Hold’ feature.
So, when the gearbox is set to drive, give the brake pedal a hard push while standing still, and the E-Class will activate the ‘Hold’ mode.
You can see whether it’s activated on the screen in front, as a big ‘HOLD’ sign will appear in capital letters.
Once activated, your vehicle will stay still even if you take your foot from the brake!
When you’re ready to take off again, all you have to do is press down gently on the accelerator to speed up as normal.
8. Open all windows with your key fob
Many E-Class owners don’t know that you can use your key fob to close or open all the windows and even the sunroof automatically!
This is an excellent tip if you want to get some fresh air into your car quickly or if you want to cool down the interior on a hot day.
So, here’s how to do it:
- Press and hold the ‘Unlock’ button on your key fob to open all windows (and the sunroof if you have it).
- Press and hold the ‘Lock’ button on your key fob to close all windows (and the sunroof if you have it).
From deactivating the keyless entry feature to opening all windows automatically with your key fob, these features will help you use the hidden powers of your Mercedes.
