Mercedes-Benz GL-Class: Restarting the tire pressure monitor
WARNING 
It is the driver's responsibility to set the tire
pressure to the recommended cold tire
pressure. Underinflated tires affect the ability
to steer or brake the vehicle. You might lose
control over the vehicle.
When you restart the tire pressure monitor, all existing warning messages are deleted and the warning lamps go out. The monitor uses the currently set tire pressures as the reference values for monitoring.
The tire pressure monitor must be restarted when you set the tire pressure to a new value (as a result of changed drive or load characteristics, for example). The tire pressure monitor then monitors the new tire pressure values.
Restart the tire pressure monitor after you have set the tire pressure to the value recommended for the desired driving situation. Only correct tire pressures on cold tires. Comply with the recommended tire pressures on the tire and loading information table on the B-pillar on the driver's side. Additional tire pressure values for driving at high speeds or with heavy loads can be found in the tire pressure table on the inside of the fuel filler flap.
► Make sure that the tire pressure is
correct
on all four wheels.
► Make sure that the SmartKey is in position
2 in the ignition lock.
► Press and hold the V or U button on
the multifunction steering wheel until the standard display appears in the
multifunction display.
► Press and hold the
button
until the tire pressure of each wheel or the
Tire pressure displayed after
driving for a few minutes message
appears.
► Press the reset button on the instrument
cluster.
The Restart tire pressure monitor? message appears in the multifunction display.
If you wish to confirm the restart:
► Press the
button.
The Tire Pressure Monitor Restarted message appears in the multifunction display.
After driving for a few minutes, the system checks whether the current tire pressures are within the specified range. The new tire pressures are then accepted as reference values and monitored.
If you wish to cancel the restart:
► Press the
button.
The tire pressure values stored at the last restart will continue to be monitored.
