Tire Pressure Monitor (TPM) monitors your Mercedes-Benz tire pressure of all four tires and will warn you if any of the tires has low pressure. Often referred to as TPMS, it has sensors that are installed at all the four tires and readings from each tire are transmitted to the TPMS control unit. It is important to understand that even though TPMS reset and programming are used interchangeably, they are different procedures. Reset or relearn is when you set new pressure on your tires, install a new OEM TPMS sensor or rotate tires and the car needs to recognize the new location of the TPMS sensors. TPMS programming is when manual programming is required prior to installing a universal TPMS sensor. During programing the mechainc will copy the ID of the defective TPMS sensor and copy it to the new TPMS sensor. This procedure is also referred to as TPMS cloning.
In this article we will discuss:
Depending on the Mercedes model you have try one of the following instructions.
Before you can reset TPM on your Mercedes you need to first inflate all tires to recommended PSI. Check the recommended pressure on the sticker found underneath the fuel cap door. As you carry this procedure turn the ignition to on but do not start the engine.
How to reset (program) TPM (TPMS) in most Mercedes-Benz
Correct the tire pressure. Add air as to bring the tire pressure within range. You can add air to your Mercedes by going to a service station or you can use a small 12 air compressor gauge to do this at home. We would recommend a portable air compressor such as the HV-35 SuperFlow 12-volt compressor. It has a built-in gauge and is able to inflate a tire in 3 minutes plus its inexpensive.

If the instructions above did not work try the following instructions.
To relearn new sensors ID’s car must be driven 10 mins at over 15 mph.
If you need new TPMS Tire Pressure Monitoring Sensor for Mercedes C CL CLK CLS E G GL ML check the following listing on Amazon. You will find aftermarked and genuince MB TPMS sensors. They cost a fraction of the price compared to what you may pay at a dealer and can be installed by most tire shops.
There are many universal TPMS sensors that can be used on Mercedes-Benz. These are known as cloneable sensors. Typically these sensors require programming but there are some units such as multi-fit Universal Programmable System Kit that doesn’t require factory relearn process.
We would recommend that every new TPMS sensor be relearned to your vehicle as recommended by the manufacturer whether you are using an aftermarket or genuine OE sensor. Aftermarket sensors may need special programming to installation and relearn. This applies to many “programmable”, “universal” or “cloneable” sensors.
It is possible to even install TPMS on your Mercedes-Benz if it didn’t come with the system installed at the factory. In order to install the TPMS on your Mercedes, you need to first check that you have TPM Control Unit and the receiving module installed. If you have the TPMS module installed you can watch the following video on how to install TPMS in your Mercedes-Benz. You will need four new genuine Mercedes-Benz TPMS monitoring sensors which you can purchase on Amazon (check price) for much less than the dealer.
Yes, if you can clone the ID of the existing TPMS sensor. If you copy the ID of the existing sensor and write it on the new sensor, then you don’t need to carry any programming at the dealer. This is possible with TPMS sensor such as Dorman Multi-fit Universal Tire Pressure Monitoring System Kit. If you take a look at that link, there is a video on the product description that explains in detail how this works.
Mercedes TPMS frequency requirements: 315 MHz sensors in US and 433 MHz sensors in Europe.
Inside the Mercedes TPMS you will find a lithium ion battery. The life span of Mercedes TPMS sensors can vary between 6 to 10 years, in some cases they can last even longer. Avoid using products such as Fix-a-flat as they will drastically reduce the life of the TPMS sensors.

The Tire Pressure Monitoring System, or TPMS, is a great tool to have on any vehicle.
Not only is low tire pressure potentially dangerous, because it can lead to a flat tire or blowout, but it also causes your vehicle to suffer in performance and fuel-efficiency. The TPMS helps ensure that each of your tires are running the way they should be and will alert you if something isn't right.
The Mercedes-Benz Tire Pressure Monitoring System is even more advanced. Not only will it alert you if your tire pressure is too low, but you're also able to check each tire's pressure whenever you want via your instrument cluster.
If you see the dreaded yellow warning light, you'll want to follow the instructions above to see which tire is being the problem.
Then you'll want to test it manually, with a hand-held pressure gauge, and fill or let out air as needed.
Once everything checks out, you can go back into the "Tire Pressure" menu following the directions above. Sometimes it will say "tire pressure will display after a few minutes" and all you'll need to do is drive for a while and check again.
You can also reset it manually by pressing the down arrow on your steering wheel to restart the TPMS from the "Tire Pressure" menu. Press "OK" and new tire pressure numbers should appear, and the warning light should go away.
If you ever need any help with your tires, or any other Mercedes-Benz maintenance, feel free to schedule an appointment with our Mercedes-Benz of West Houston service center.

3 completes Mercedes gl (glc) models with 2 types of tire pressure monitoring systems. They differ in control units:
Wheel pressure sensors are of the internal type. Are established in a regular place of each wheel (including a spare tire). Outside, they look like a nipple valve closed with a cap. The inner, sensitive part of the sensor is behind the tire. It is the basis of the entire device.
Pressure sensor
The control system, abbreviated RDK in Mercedes gl (glc) vehicles, has the following features:
The system works online, while the vehicle is in motion and while parked. It takes into account the factors of ambient temperature, speed of movement and the condition of the roadway. The information is transmitted to the multifunctional display.
Mercedes
Pressure sensor for each wheel, in Mercedes gl tires identified with the main unit. It transmits information to it, in the form of a radio signal, through individual antennas. The autonomy of its work is provided by a rechargeable battery. Its service life is at least 5 years. After the battery fails, the sensor changes to a new node.
The RDK tire pressure system in Mercedes gl (glc) vehicles works automatically using information from the on-board computer. Performs self-activation in case of:
If tire inflation is not recognized, it is necessary to activate the pressure sensor in the Mercedes using manual mode.
The reset button on the steering wheel is used for the procedure. The completion of the test will be indicated by an inscription on the system display.
The tire pressure monitoring system requires tire pressure sensors to be installed on replacement (seasonal) wheels. They can be rearranged from factory disks. Buy new ones, specifying the article and series. They must be compatible with the RDK central unit.
