Anti-theft protection

Function of the immobilizer
The immobilizer prevents your vehicle from being
started without the correct SmartKey.
The immobilizer is automatically activated when
the ignition is switched off and deactivated when
the ignition is switched on.
When leaving the vehicle, always take the Smart‐
Key with you and lock the vehicle. Anyone can
start the engine if a valid SmartKey has been left
inside the vehicle.

(yet the vehicle's battery is charged), the
system is not operational. Contact an
authorized Mercedes-Benz Center or call
1-800-FOR-MERCedes (in the USA) or
1-800-387-0100 (in Canada).
