Folding exterior mirrors in and out
Pressing button3 allows you to fold mirrors
in and out up to a speed of approx. 20 mph/
30 km/h. This is advantageous, for example, in
car washes, narrow streets or for bringing mir-
r o r s t h a t h a v e b e e n m a n u a l l y f o l d e d - i n b a c k i n t o
the correct position. Folded-in mirrors automat-
ically fold down at a speed of approx. 25 mph/
40 km/h.
Automatic functions
>Below a certain outdoor temperature, both
exterior mirrors are automatically heated
when the motor is running or the ignition is
switched on.
>When the vehicle is moving forward, the
interior and exterior mirrors dim as a func-
tion of the incoming light.
The interior mirror is provided with two photo-
cells to control its automatic dimming function.
One is integrated into the mirror glass, refer to
arrow, while the other is located at a position
slightly offset from this on the back of the mirror
housing.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Also
do not attach stickers to the windshield in front
of the mirror.

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 at all or is burned inade-
quately and there is a danger of overheating and
damage to the catalytic converter.<
Special starting conditions
Depress the accelerator pedal halfway 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 engine off
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 handbrake.
2.Move selector lever into a drive position.
3.Briefly press Start/Stop button.
A signal sounds when the position N is
engaged and the handbrake is not set when
switching off the engine.
Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.

Driving

Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is engaged.
Indicator lamp for Canadian models.
Engaging
The lever engages automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to engage the hand-
brake while the vehicle is in motion, do not pull
it too strongly. In doing so, continuously press
the button of the handbrake lever. Otherwise,
excessive pressure can lead to the rear wheels
locking up and loss of traction – fishtailing – at
the rear axle.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is engaged.<
Sequential Manual
Transmission with Drivelogic
The concept
The SMG Sequential Manual Transmission
with Drivelogic is an automated manual trans-mission in which an electrohydraulic system
handles the clutching and gear changes.
The Sequential Manual Transmission is oper-
ated with the selector lever and two shift pad-
dles on the steering wheel.
It offers the following functions:
>Choice of manual or automatic mode:
Sequential mode or Drive mode
>Selection option between different driving
programs, Drivelogic, refer to page54
>Upshift display, shift lights, refer to page55
>Automatic downshifting and prevention of
incorrect shifting even in sequential opera-
tion
>Automatic double clutching
Selector lever positions
>R: Reverse gear
>N: Neutral, idle
>Β: Drive position:
>+: manual upshifting

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 page46. 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.
