Indicator and warning lamps
The concept
The indicator and warning lamps can light up in 
different combinations and colors.
When the engine is started or the ignition is 
switched on, some lamps are checked for 
proper operation and light up briefly in the pro-
cess.
Explanatory text messages
Text messages at the bottom edge of the Con-
trol Display explain the meaning of the indicator 
and warning lamps displayed.
You can consult Check Control for additional 
information, e.g. regarding the cause of a mal-
function or the appropriate actions to take, refer 
to page73.In urgent cases, this information will be shown 
as soon as the corresponding lamp lights up.
Indicator lamps without text messages
The following indicator lamps indicate that cer-
tain functions are activated or deactivated:

M Engine Dynamic Control
With M Engine Dynamic Control you can influ-
ence how sporty the reaction of your vehicle to 
accelerator pedal movements is to be. Three 
programs are available for engine control.
"P 400" program
In the "P 400" program the engine reacts gently 
to the movement of the accelerator pedal. This 
is, for example, ideal for city driving or driving on 
snow. In the process, the fuel consumption is 
minimal and the engine output is reduced.
"P 500" program
The "P 500" program provides maximum per-
formance and more spontaneous reaction of 
the engine to accelerator pedal movements.
"P 500 Sport" program
In the "P 500 Sport" program the engine reacts 
especially spontaneously and uncompromis-
ingly sporty with maximum performance to 
accelerator pedal movements.
Selecting program
Each time the engine is started, the "P 400" 
program is activated.
Press the POWER button to activate the 
"P 500" program. Pressing the POWER button 
repeatedly switches between the programs 
"P 400" and "P 500".
You can also activate your preferred program 
with the   button on the steering wheel, refer 
to MDrive on page54. You can only activate the 
"P 500 Sport" program with MDrive.For the programs "P 500" and "P 500 Sport" 
the LED in the POWER button lights up.

3Automatic headlamp control,
 daytime run-
ning lamps
* and Adaptive Head Light*
Parking lamps
In switch position1, the front, rear and side 
vehicle lighting is switched on. You can use the 
parking lamps for parking.
The parking lamps drain the battery. Do 
not leave them switched on for long peri-
ods of time, otherwise it may no longer be pos-
sible to start the engine. It is preferable to 
switch on the roadside parking lamps on one 
side, refer to page97.<
Low beams
The low beams light up when the light switch is 
in position 2 and the ignition is on.
If the light switch remains in position 2, the 
exterior lamps are switched off automatically 
when the driver's door is opened while the igni-
tion is off.
Switch on the parking lamps if required as 
described under Parking lamps.
Automatic headlamp control
In switch position3, the system activates the 
low beams and switches them on or off in 
response to changes in ambient light condi-
tions, for instance, in a tunnel, at dawn and dusk 
and in case of precipitation. Adaptive Head 
Light
* is active. The LED next to the symbol is 
illuminated when the low beams are on.
A blue sky with the sun low on the horizon can 
cause the lights to be switched on.
If desired, the light switch can be left in posi-
tion3. The exterior lighting is automatically 
switched off after switching off the vehicle.
The automatic headlamp control cannot 
serve as a substitute for your personal 
judgment in determining when the lamps 
should be switched on in response to ambient 
lighting conditions. For example, the sensors 
cannot detect fog of hazy weather. To avoid 
safety risks, you should always switch on the 
low beams manually under these conditions.<
Pathway lighting
When you activate the headlamp flasher after 
parking the vehicle and switching off the lamps, 
the low beams will come on for a brief period. 
You can set the duration or deactivate the func-
tion via iDrive.
iDrive, for explanation of principle, refer to 
page16.

If desired, the light switch can remain in posi-
tions0, 1 or 3. 
In positions0 and 3 the exterior lighting is auto-
matically switched off after the vehicle is 
switched off. In position1 the parking lamps 
light up after the ignition is switched off.

switched on.
The setting is stored for the remote control cur-
rently in use.
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp 
control system that enables better illumination 
of the road surface. Depending on the steering 
angle and other parameters, the light from the 
headlamp follows the course of the road.
Activating Adaptive Head Light
In switch position3, the Adaptive Head Light is 
active and the automatic headlamp control is 
switched on, refer to page95.
To avoid blinding oncoming traffic, the Adaptive 
Head Light is not active when driving in reverse 
and points toward the passenger side when the 
vehicle is stopped.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. The Adaptive Head Light 
is malfunctioning or has failed. Have the system 
checked as soon as possible.
