DrivingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Start/Stop button The concept Pressing the Start/Stop button
switches the ignition on or off
and starts the engine.
Steptronic transmission: The
engine starts if the brakes are
stepped on while pressing the Start/Stop but‐
ton.
Manual transmission: The engine starts with
the clutch pedal pressed when the Start/Stop
button is pressed.
Ignition onSteptronic transmission: Press the Start/Stop
button without stepping on the brake.
Manual transmission: Press the Start/Stop but‐
ton without stepping on the clutch pedal.
All vehicle systems are ready for operation.
Most of the indicator and warning lights in the
instrument cluster light up for a varied length
of time.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.Ignition off
Steptronic transmission: Press the Start/Stop
button again without stepping on the brake.
Manual transmission: Press the Start/Stop but‐
ton again without stepping on the clutch pedal.
All indicator lights in the instrument cluster go
out.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
P when the ignition is switched off
P is engaged automatically when the ig‐
nition is switched off. When in an automatic car wash, e.g., ensure that the ignition is not
switched off accidentally.◀
The ignition automatically cuts off while the
vehicle is stationary and the engine is stopped:▷When locking the vehicle, and when the
low beams are activated.▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available
when the low beams are turned off.▷When opening or closing the driver door, if
the driver's safety belt is unbuckled and
the low beams are turned off.▷While the driver's safety belt is unbuckled
with driver's door open and low beams off.
The low beams switch to parking lights after
approx. 15 minutes of no use.
Radio ready state
Activate radio-ready state:
▷When the engine is running: press the
Start/Stop button.
Some electronic systems/power consumers
remain ready for operation.

The radio-ready state switches off automati‐
cally:▷After approx. 8 minutes.▷When the vehicle is locked using the cen‐
tral locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
The radio-ready state remains active if, e.g.,
the ignition is automatically switched off for the
following reasons:
▷Opening or closing the driver's door.▷Unfastening of the driver's safety belt.▷When automatically switching from low
beams to parking lights.
If the engine is switched off and the ignition is
switched on, the system automatically
switches to the radio-ready state if the lights
are turned off or, if correspondingly equipped,
the daytime running lights are activated.
Starting the engine
Hints Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Unattended vehicle
Do not leave the vehicle unattended with
the engine running; doing so poses a risk of
danger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in selector lever position P or N to pre‐
vent the vehicle from moving.◀
Repeated starting in quick succession
Avoid trying to start the vehicle repeat‐
edly and in quick succession. Otherwise, the
fuel is not burned or is inadequately burned,
posing a risk of overheating and damage to the
catalytic converter.◀
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving at
moderate engine speeds.
Diesel engine
If the engine is cold and temperatures are be‐
low approx. 32 ℉/0 ℃, the start process may
be delayed somewhat due to automatic pre‐
heating.
A Check Control message is displayed.
