made outside of MDrive.
8.Press the controller.
The setting is stored for the remote control cur-
rently in use.
Activating settings
Press the   button on the steering wheel.
The indicator lamp in the instrument 
cluster lights up. The settings made on 
the Control Display for the functions 
contained in MDrive are active.
Pressing the button again deactivates MDrive.
If the indicator lamp flashes after pressing 
the button, MDrive was unable to react, as 
the ABS Antilock Brake System or DSC 
Dynamic Stability Control is currently control-
ling the vehicle stability. Press the  button 
again when the indicator lamp no longer 
flashes.<
Even with MDrive activated, you can change 
individual settings outside MDrive, e.g. with the 
buttons in the center console. To reactivate all 
settings made for MDrive on the Control Dis-
play: press the   button twice.

Starting engine
Do not run the engine in closed rooms, 
otherwise the inhaling of toxic exhaust 
gases can cause unconsciousness and death. 
The exhaust gases contain carbon monoxide, 
an odorless and colorless, but highly toxic gas. 
Never leave an unattended vehicle with the 
engine running, as such a vehicle represents a 
potential safety hazard. 
Before leaving the vehicle with the engine run-
ning, move the selector lever into the N position 
and set the handbrake, otherwise the vehicle 
can begin to roll.<
When starting the engine, do not press the 
accelerator pedal.
Do not allow the engine to warm up by leaving it 
running while the vehicle remains stationary. 
Instead, begin to drive immediately at a moder-
ate engine speed.
Do not press the brake pedal as long as 
you do not want to start the engine. The 
engine starts immediately when you briefly 
press the Start/Stop button with the brake 
pedal depressed.<
1.Depress brake pedal.
2.Place selector lever in position N.
3.Briefly press Start/Stop button.
The system responds by automatically engag-
ing the starter for a certain period and automat-
ically disengaging it as soon as the engine 
starts.If the engine does not start, shift back to 
the last selector lever position selected, 
refer to the instrument cluster display or the 
selector lever. Then select the position N.
You cannot start off with the hood open.
When the engine is cold, the exhaust system 
has a slightly metallic undertone due to the sys-
tem design.<
Avoid frequent starting in quick succes-
sion or repeated starting attempts in 
which the engine does not start. Otherwise, the 
fuel is not burned or inadequately burned and 
there is a danger of overheating and damaging 
the catalytic converter.<
Special starting conditions
Depress the accelerator pedal half way when 
starting the engine in the following situations:
>The engine fails to start on the first attempt, 
e.g. if it is very hot or cold.
>The engine is started at very low tempera-
tures, below approx. + 57/– 156, at high 
altitudes, over approx. 3,300 ft/1,000 m.
Switching off engine
Do not remove the remote control from 
the ignition lock while the vehicle is roll-
ing, otherwise the steering wheel lock would 
engage while steering. 
When leaving the vehicle, always take the 
remote control with you. 
When parking on a downhill incline, apply the 
handbrake, as otherwise the vehicle could roll 
away.<
1.Apply the handbrake.
2.Engage a driving position.
3.Briefly press the Start/Stop button.
A signal sounds when the position N is 
engaged and the handbrake is not set when 
switching off the engine. 

Driving
56
R Reverse
Select only when the vehicle is stationary.
N Idle
Always engage before starting engine.
If the driving situation requires, e.g. when down-
shifting on a slippery road surface, the Sequen-
tial Manual Transmission automatically 
clutches and then declutches again, i.e. it is not 
necessary to engage idling manually.
N is automatically engaged after just a 
few seconds when you open the driver's 
door or the hood with the engine running and do 
not operate either pedals, shift paddles or the 
selector lever. In these cases, to start off after 
closing the driver's door or the hood, first move 
the selector lever into the position N and then 
into the drive position.<
S Sequential mode
You can shift up and down using the shifting 
paddles or the selector lever. You do not need 
to remove your foot from the accelerator to do 
so.
After every engine start, as soon as the selector 
lever is pushed to the right into the drive posi-
tion Β and the brake pedal is pressed, the 
Sequential mode is activated.
Starting off is also possible on a level road sur-
face in second gear, e.g. in case of ice.
In the following situations, the Sequential Man-
ual Transmission thinks for you:
>Upshifts and downshifts are executed only 
when they will result in a plausible combina-
tion of engine and vehicle speed; thus, for 
example, a downshift that would cause the 
engine to overrev will not be executed by 
the system.
>When the vehicle is stationary, the trans-
mission automatically downshifts into first 
gear.
>Shortly before dropping below a gear-
dependent minimum speed, the transmis-
sion downshifts automatically even without 
your intervention.
D Drive mode
In the Drive mode, all forward gears are shifted 
automatically.
Shifting from Sequential mode to Drive mode: 
press selector lever to the right toward D/S.
To switch back into the Sequential mode: press 
selector lever to the right again toward D/S or 
shift using the shift paddles or the selector 
lever.
Kick-down: for rapid acceleration, e. g. when 
passing, press the accelerator pedal as far 
down as it will go. You achieve maximum accel-
eration.

Drivelogic
With Drivelogic various driving programs are 
available to you.
Each time you change between the Sequential 
mode and the Drive mode, the driving program 
last selected in the respective mode is active. 
Exception: after the first change from the 
Sequential to the Drive mode, driving program 3 
is active. 
In Drive mode
Five driving programs, from relaxed 1 to sporty/
highly dynamic 5 are available for selection.
In Sequential mode
You can choose from six driving program from 
balanced/dynamic 1 to sporty/purist 6.
Each time the engine is started, driving pro-
gram 3 is activated.
The sporty/purist driving program 6 is only 
available with the DSC Dynamic Stability Con-
trol deactivated, refer to page75. When DSC is 
activated, the system switches from driving 
program 6 to 5.
To maintain vehicle stability, always drive 
with the DSC switched on when possi-
ble.<
Selecting driving program with button 
in center console
Press the button repeatedly until the desired 
driving program is displayed in the instrument 
cluster, refer to page56.

You can also activate your preferred driving pro-
gram with the   button on the steering wheel,

Cruise control
The concept
The cruise control is available for use at speeds 
of approx. 20 mph/30 km/h and higher. The 
vehicle stores and maintains the speed that you 
set using the lever mounted on the steering col-
umn.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding 
roads, in heavy traffic or in poor road conditions 
such as snow, rain, ice, and loose road surface. 
Otherwise you could loose control of the vehi-
cle and cause an accident.<

4Resuming stored speed
Maintaining speed, storing speed, 
and accelerating
Press lever to resistance point, arrow 1: 
The speed currently being driven is maintained 
and stored. The display1 in the speedometer, 
see below, indicates this regulated speed. 
Every time you press the lever, the vehicle's 
speed increases by roughly 1 mph/1 km/h.
Press lever to resistance point for a longer time: 
The vehicle accelerates without pressure on 
the accelerator pedal. The system maintains 
and stores your current speed as soon as you 
release the lever.Press the lever beyond the resistance point: 
increase speed by 5 mph/10 km/h.
If, on a downhill grade, the engine's braking 
effect is not sufficient, the controlled speed can 
be exceeded. Speed can drop on uphill grades if 
the engine output is insufficient.
Maintaining speed, storing speed, and 
decelerating
Pull the lever, arrow2: 
Functions are the same as1, only the vehicle 
speed is reduced.
Interrupting cruise control
Press the lever up or down, arrow3.
In addition, cruise control is automatically deac-
tivated:
>When the brakes are applied
>For manual shifting with the shift paddles or 
the selector lever
>When the DSC comes on
Resuming stored speed
Press button4: 
The stored speed is resumed and maintained.
Deactivating system
When the ignition is switched off, the system is 
deactivated and the stored speed is deleted.
