Seat heater
The seat heaters can be switched on with the electronic
key in starter switch positions 1 or 2.
The buttons are located on each door.
Notes:
When in operation, the seat heater consumes a large
amount of electrical power. It is not advisable to use the
seat heater longer than necessary.The seat heaters may automatically switch off if too
many power consumers are switched on at the same
time or if the battery charge is low. In this case, one or
both indicator lamps will blink.
The seat heaters switch back on again automatically as
soon as sufficient voltage is available.
If the blinking of the indicator lamps is distracting to
you, the seat heaters can be switched off.

turn electronic key completely to the left and repeat
starting the engine.After several unsuccessful attempts, have the system
checked at the nearest authorized Mercedes-Benz

Due to the installed starter non-repeat feature, the
electronic key must be turned completely to the left
before attempting to start the engine again.
