Tire pressure loss warning system (Canada only)

Mercedes-Benz GL-Class / Mercedes-Benz GL-Class Owners Manual / Wheels and tires / Check / Tire pressure loss warning system (Canada only)

General notes

While the vehicle is in motion, the tire pressure loss warning system monitors the set tire pressure using the rotational speed of the wheels. This enables the system to detect significant pressure loss in a tire. If the speed of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning message will appear in the multifunction display.

You can recognize the tire pressure loss warning by the Run Flat Indicator Active Press 'OK' to Restart message which appears in the Serv. menu of the multifunction display. Information on the message display can be found under "Restarting the tire pressure loss warning system"  .

Important safety notes

The tire pressure warning system does not warn you of an incorrectly set tire pressure.

Observe the notes on the recommended tire pressure  .

The tire pressure loss warning does not replace the need to regularly check the tire pressure. An even loss of pressure on several tires at the same time cannot be detected by the tire pressure loss warning system.

The tire pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tire is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering maneuvers.

The function of the tire pressure loss warning system is limited or delayed if: Х snow chains are mounted on your vehicle's tires.

Х road conditions are wintry.

Х you are driving on sand or gravel.

Ryou adopt a very sporty driving style (cornering at high speeds or driving with high rates of acceleration).

Ryou are towing a very heavy or large trailer.

Ryou are driving with a heavy load (in the vehicle or on the roof).

The recommended tire pressures can be found on the Tire and Loading Information placard on the B-pillar on the driver's side or the tire pressure table on the fuel filler flap.
