Mercedes is known for its luxury vehicles and sophisticated features. One feature that sets Mercedes apart from other brands is the ESP (Electronic Stability Program). This system helps to keep your vehicle stable and control skidding.
If you ever find yourself in a situation where your Mercedes is acting up, you may need to reset the ESP system. To do this you will have to use a specific button.
The ESP reset button is located on the lower left side of the steering wheel. To reset the system, you will need to press and hold this button for approximately five seconds. Once you have done this, the system should be reset and the ESP light on your dash should turn off.
The position of the ESP reset button is the same on all Mercedes models. If you are having trouble finding it, be sure to consult your owner’s manual. This can be a great resource for finding the location of specific buttons and features in your vehicle.
What Does ESP Mean
The electronic Stability Program (ESP) is a system in Mercedes vehicles that uses sensors to monitor your speed and the vehicle’s direction.
If it detects that the vehicle is veering off course, it will automatically apply the brakes to individual wheels and reduce engine power. This helps to keep the vehicle under control and prevents skidding or fishtailing.
How ESP Works
The ESP forms part of the ABS (anti-lock braking system). This system uses sensors to monitor the speed of each wheel. If one of the wheels is turning faster than the others, it means that the vehicle is starting to skid.
The ESP will then apply the brakes to that wheel and reduce engine power. This helps to bring the vehicle back under control.
The ESP system is comprised of several different parts, including:
Snímač zrychlení
This sensor monitors the speed of the vehicle and detects when it is veering off course.
Brake Pressure Sensor
This sensor monitors the pressure in the brakes. If the pressure gets too high, it means that the ESP is being activated.
ESP Controller
The controller is the brain of the system. It uses information from the acceleration and brake pressure sensors to determine when the ESP should be activated.

When Should I Reset My ESP
There are a few different situations in which you may need to reset your ESP. Here are some of the most common reasons:
1. The ESP Light Is On
When the ESP light on your dash is lit up, it means that the system has been activated. In most cases, you will not need to reset the system. The ESP light will go off on its own once the vehicle is back under control.
2. You’ve Been in a Minor Accident
In case you’ve been in a minor accident, the ESP system may have been activated. If this happens, you will need to reset the system before you can continue driving.
3. You’ve Driven Through Deep Water
If you’ve driven through deep water, water may have gotten into the ESP sensors. This can cause the system to malfunction. To fix this, you will need to reset the system.
What Causes Mercedes ESP Light to Come On
There are several causes for an ESP failure on your Mercedes-Benz. Instead of guessing at what may be wrong, it is preferable and less expensive to use a diagnostic scanner that can read the ESP fault codes.
The fault code will show which one of the following is defective. It makes troubleshooting considerably easier and cheaper. Some of the problems that can cause the Mercedes-Benz ESP light to come on are:
ABS Pump Motor
One of the more common failures, the ABS pump motor may fail and cause the ESP light to come on. The ABS pump is responsible for providing hydraulic pressure to the ABS. If it fails, the entire system will not work correctly.
ESP Sensor
The ESP sensor is responsible for monitoring the speed of the wheels and detecting when the vehicle is veering off course. If this sensor fails, it can cause the ESP light to come on.
Brake Pressure Sensor
A defective brake pressure sensor can also cause the ESP light to come on. This sensor is responsible for monitoring the pressure in the brakes. If it fails, it can cause the ESP system to malfunction.
Nízké napětí baterie
A low battery voltage can also cause the ESP light to come on. This is because the system needs a certain amount of power to function correctly. If the battery voltage is low, it can cause the system to fail.
Snímač úhlu řízení
The steering angle sensor is responsible for detecting the position of the wheels. If this sensor fails, it can cause the ESP light to come on.ESP ControllerThe controller is the brain of the system.
It uses information from the acceleration and brake pressure sensors to determine when the ESP should be activated. When this component fails, it can cause the ESP light to come on.
How to Reset the ESP
Now that we know what the ESP means and the reason it may need to be reset, let’s go over the steps on how to do it.
Step One: Locate the Button
The first step is to locate the ESP reset button. This button is located in various regions across the dash of different vehicles. However, in Mercedes models, the button is always on the lower left side of the steering wheel.
Step Two: Press and Hold
