Deactivating drive-ready state
After stopping the vehicle:
1. Set the parking brake.
2. Engage selector lever position P.
3. Press the Start/Stop button.
After parking the vehicle, you may hear
noises due to operation of the hybrid sys-
tem, such as for cooling of the high-voltage
battery.
Safety measure
The drive-ready state is deactivated auto-
matically after approx. 10 minutes when the
vehicle is stationary if, with the selector
lever in position P or N, the driver's door
has been opened and neither the brake
pedal nor the accelerator pedal have been
depressed.
Before driving into a vehicle wash
So that the vehicle can roll into a vehicle
wash, follow instructions for going into an
automatic vehicle wash, refer to page 314.
Auto Start/Stop function
Concept
The Auto Start/Stop function helps save
fuel. The system switches off the combus-
tion engine when conditions for electric
driving have been met. The ignition or
drive-ready state remains switched on.
General information
READY is displayed in the instrument clus-
ter. If necessary, the combustion engine
starts automatically.
The combustion engine is also stopped dur-
ing the trip when rolling without accelera-
tion or braking. This driving condition, in
which the vehicle is traveling without
power and energy recovery is not active, is
referred to as coasting, refer to page 124.
The combustion engine is not switched off
automatically in the following situations:
– The combustion engine is not at operat-
ing temperature.
– The transmission selector lever is in po-
sition M/S.
– High-voltage battery is heavily dis-
charged or vehicle electrical system is
heavily burdened.
– High stress of the automatic climate
control in the heating or cooling phase.
– The hood is unlocked.
– The vehicle is being optimized for the
current driving style, for instance dur-
ing the break-in period or after a service
appointment.
– The hybrid system is malfunctioning.
Safety mode
An automatically stopped combustion en-
gine does not start independently:
– When the driver's door is open and nei-
ther the brake nor accelerator pedal are
depressed.
– When the hood is unlocked.
The indicator lights come on. The combus-
tion engine can only be started via the
Start/Stop button.
Switching off the vehicle during an
automatic engine stop
During an automatic engine stop, the vehi-
cle can be switched off permanently, for in-
stance when leaving it.
1. Press the Start/Stop button.
– The ignition is switched off.
– The radio-ready state is activated.
