Do not rely on the Tire Pressure Monitoring System alone. Inspect the tires regularly to make sure the tire pressure is correct and check the tires for any signs of
damage, such as punctures. Remove any objects stuck in the tire tread as long as they have not punctured the inside of the tire.
Tire Pressure Monitoring System
Please read the introductory information and heed the Warnings and Notice ⇒
Introduction.
Function description
Using the ABS sensors, the Tire Pressure Monitoring System compares the RPM and thus the rolling circumference of the individual tires.
The Tire Pressure Monitoring System will not work if the ESC or ABS is malfunctioning ⇒ Troubleshooting.
The rolling circumference can change if:
The tire pressure has changed
The tire pressure is too low
The tire has structural damage
One side of the vehicle has a heavier load than the other
Snow chains are installed on the tires
A compact spare wheel has been installed
Only one wheel was replaced on each axle
The Tire Pressure Monitoring System
with snow chains.
may be delayed or not be displayed at all when driving with a sporty style, on winter or unpaved roads, or when driving
The Tire Pressure Monitoring System shows a change in the rolling circumference of the tires via the
warning light in the instrument cluster.
The recommended tire pressure for the tires installed at the factory is specified on the tire pressure sticker on the driver door pillar ⇒ Tire pressure.
The tire pressure of all tires, including the spare wheel or temporary spare wheel, must be checked once a month when the tires are cold and must correspond to th
vehicle manufacturer's specifications on the tire pressure sticker. If the size of the tires installed at the factory differs from the details on the identification label or on
the tire pressure label, the correct tire pressure must be determined.
The Tire Pressure Monitoring System is not intended to replace regular inspection and maintenance of the tires. The driver is responsible for ensuring that the
correct tire pressure is used at all times, even if the Tire Pressure Monitoring System is not showing a warning that the tire pressure is too low.
The Tire Pressure Monitoring System also has a malfunction display that is accompanied by the
warning light. In the event of a malfunction in the Tire Pressure
Monitoring System, after switching on the ignition, the warning light blinks for around one minute and then stays on.
If the Tire Pressure Monitoring System displays a malfunction, the tire pressure cannot be monitored correctly. A malfunction in the Tire Pressure Monitoring System
can have a number of causes, e.g. a wheel or a tire being replaced. After replacing a wheel or tire, you must check whether the warning light displays a system
malfunction to make sure that the Tire Pressure Monitoring System is working properly ⇒ Troubleshooting the Tire Pressure Monitoring System .
Calibrating the Tire Pressure Monitoring System
The Tire Pressure Monitoring System must be recalibrated under the following conditions:
If the tire pressures were adjusted.
If one or more wheels were changed.
If one or more wheels were repaired.
If the wheels were rotated, for example from front to rear.
The Tire Pressure Monitoring System must only be recalibrated if all tires are inflated to the correct pressure when they are cold. In order to measure the tire
pressure on cold tires, the vehicle must be left to stand for 3 hours or only be driven slowly over short distances during this time.
After being warned about a low tire pressure, switch the ignition off and back on. The Tire Pressure Monitoring System can only be recalibrated after this is
done.
1. Switch the ignition on.
2. Depending on the vehicle equipment, press the
button or function key and open the Vehicle menu in the Infotainment system ⇒ Vehicle settings menu
Or: depending on the vehicle equipment, press the
button or function key.
3. Depending on how your vehicle is equipped, tap the Setup function key.
4. Tap the Tires function key.
5. Tap the SET function key.
6. If all four tires meet the required tire pressure values, tap the Confirm function key.
After longer trips (at least 20 minutes) and different vehicle speeds, the system adapts to the new values and monitors them.
Or: Tap Cancel to cancel the process.
