Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
firmly. In doing so, continuously press the but-
ton of the handbrake lever. Otherwise, too firm
an application of the handbrake can lock up the
rear wheels and cause the rear of the vehicle to
swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally engage 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 applied.<
Manual transmission*
When shifting into 5th/6th gear, press the
gearshift lever toward the right, otherwise
an inadvertent shift into 3rd or 4th gear could
lead to engine damage.<
When engaging the 1st gear, a slight jolt may
occur. This is operation-related and no reason
for concern.
Reverse gear
Select only when the vehicle is stationary.
Press the gearshift lever to the left, overcoming
a slight resistance.
Shift lights
To achieve the best vehicle acceleration with a
sporty driving style, shift lights in the Head-Up
Display
* indicate the optimum shifting point
briefly before reaching the maximum rpm. Refer
to Shift lights, page64.

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 page63
>Upshift display, shift lights, refer to page64
>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
>–: manual downshifting
>D/S: switch between Drive mode and
Sequential mode
Shiftlock
Press the brake pedal before shifting out of N;
the shift command will not be executed unless
the brake is applied.
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.
The system shifts into N when you open
the driver's door or the hood with the
engine running and do not operate pedals, shift
paddles or the selector lever. To begin driving
after closing the driver's door or the hood, first
shift the selector lever into the N position, and
then shift into drive.<
S Sequential mode
You can shift up and down using the shift pad-
dles 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, the system will not execute a
downshift that would cause the engine to
overrev.
>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.

1.Switch on Head-Up Display, refer to Head-
Up Display on page93.
2.Select display "M View" on Head-Up Dis-
play, refer to Selecting displays on page93.
The current engine speed is highlighted on
the tachometer.
3.When approaching the maximum rpm, yel-
low illuminated fields1 of the tachometer
consecutively indicate the approaching
upshift point.
4.Shift at the latest when the red indicator
field2 lights up.
When the permissible maximum rpm is
reached, the entire tachometer begins to flash.
When the maximum rpm is exceeded, the fuel
supply is cut off to protect the engine. Always
avoid engine speeds in this range.

"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 page53. You can only activate the
"P 500 Sport" program with MDrive.

Be sure to avoid engine speeds in the red warn-
ing field. At high revs in this range, the flow of
fuel is interrupted to protect the engine.

Engine oil temperature*
The general operating temperature lies
between 1757/806 and 2507/1206. Do
not exceed a value of approx. 2657/1306.
If the engine oil temperature is too high, the per-
missible engine speed, and with it the available
engine output is reduced.
Fuel gauge
Fuel tank capacity: approx. 18.5 US gal/
70 liters. You can find information on refueling
on page200.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
