Practical advice

Possible solution
Have the tyre pressure loss warning*
checked at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Change the batteries ( page 354).
Stop your vehicle as soon as it is safe to do
so.
Look for the key.
Switching off the engine prevents you from
locking the vehicle centrally or starting the
engine.
Operate the vehicle using the key function.
Alter the position of the key in the vehicle.
Insert the key into the ignition lock and op-
erate the vehicle using the ignition lock.
