DrivingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Start/Stop button
The concept Pressing the Start/Stop button
switches the ignition on or off and
starts the engine.
The engine starts if the brake
pedal is pressed when you press
the Start/Stop button.
Ignition on
Press the Start/Stop button, and do not press on
the brake pedal at the same time.
All vehicle systems are ready for operation.
Most of the indicator and warning lamps in the
instrument cluster light up for varying lengths of
time.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
The ignition switches off automatically:▷When the vehicle is locked, if the low beams
are switched on.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.Note
If the engine is switched off and the ignition is
switched on, the system automatically switches
to the radio ready state when the door is opened
if the lights are switched off or the daytime run‐
ning lights are switched on.
Ignition off
Press the Start/Stop button again, and do not
press on the brake pedal at the same time.
All indicator lamps 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.
Transmission position P with the ignition
off
When the ignition is switched off, position P is
engaged automatically. When in an automatic
car wash, for example, ensure that the ignition is
not switched off accidentally.◀
Ignition automatically cuts off while the vehicle
is stationary and the engine is stopped:▷During locking, also with the low beams ac‐
tivated.▷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 switched off.▷When opening and closing the driver door, if
the driver's seat belt is unbuckled and the
low beams are switched off.▷While the driver's seat belt is unbuckled, if
the driver's door is open and the low beams
are switched off.
When the ignition is switched off, by opening or
closing the driver's door or unbuckling the driv‐
er's seat belt, the radio ready state remains ac‐
tive.

Starting the engine
General information Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of 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 dan‐
ger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in position P or neutral to prevent the
vehicle from moving.◀
Repeated starting in quick succession
Avoid repeated unsuccessful attempts to
start the vehicle or starting the vehicle several
times 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 mod‐
erate engine speeds.
Starting the engine Press on the brake pedal and
press the Start/Stop button.

the vehicle as required
Set the parking brake firmly when parking; oth‐
erwise, the vehicle could roll. On steep upward
and downward inclines, further secure the vehi‐
cle, for example, by turning the steering wheel in
the direction of the curb. ◀
Before driving into a car wash
In order for the vehicle to be able to roll into a car
wash, heed the information regarding Washing
