DrivingVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Start/Stop button The concept Pressing the Start/Stop button
switches the ignition on or off
and starts the engine.
Steptronic transmission: the en‐
gine starts in selector lever posi‐
tion P or N with the brake pedal pressed when
you press the Start/Stop button.
Manual transmission: the engine starts with the
clutch pedal pressed when the Start/Stop but‐
ton is pressed.
Ignition on Manual transmission: press the Start/Stop but‐
ton without stepping on the clutch pedal.
Steptronic transmission: 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 lights in the
instrument cluster light up for a varied length of
time.To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
Ignition off
Manual transmission: press the Start/Stop but‐
ton again without stepping on the clutch pedal.
Steptronic transmission: shift to selector lever
position P, press the Start/Stop button again
without stepping on the brake.
All indicator lights 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.
The ignition is switched off automatically in the
following situations while the vehicle is station‐
ary and the engine is off:▷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 turned off.▷When opening and closing the driver door,
if the driver's safety belt is unbuckled and
the low beams are turned off.▷While the driver's safety belt is unbuckled
with driver's door open and low beams off.▷The low beams switch to parking lights af‐
ter approx. 15 minutes of no use.
Radio ready state
Activate radio-ready state: when the engine is
running: press the Start/Stop button.

▷After approx. 8 minutes.▷When the vehicle is locked using the central
locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
The radio-ready state remains active if, for ex‐
ample, the ignition is automatically switched off
for the following reasons:
▷Opening or closing the driver's door.▷Unfastening of the driver's safety belt.▷When automatically switching from low
beams to parking lights.
If the engine is switched off and the ignition is
switched on, the system automatically switches
to the radio-ready state if the lights are turned
off or, if correspondingly equipped, the day‐
time running lights are activated.
Starting the engine
Information DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of the
vehicle. There is danger to life. Keep the ex‐
haust pipe free and ensure sufficient ventila‐
tion. ◀
WARNING
An unsecured vehicle can put itself into
motion and roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a slope, turn the
front wheels in the direction of the curb.▷On uphill grades or on a slope, also secure
the vehicle, for example with a wheel
chock. ◀
CAUTION
In the case of repeated starting attempts
or repeated starting in quick succession, the
fuel is not burned or is inadequately burned.
The catalytic converter can overheat. There is
risk of property damage. Avoid repeated start‐
ing in quick succession. ◀

Washer fluid
General information All washer nozzles are supplied from one reser‐
voir.
Prepare and dilute a mixture of tap water,
windshield washer concentrate, and possibly
antifreeze prior to filling.
Recommended minimum fill quantity:
0.2 US gal/1 liter.
Information WARNING
Some antifreeze agents can contain
harmful substances and are flammable. There
is risk of fire and risk of injuries. Observe the in‐
structions on the containers. Keep antifreeze
away from ignition sources. Do not refill oper‐
ating materials into different bottles. Store op‐
erating materials out of reach of children.
United States: The washer fluid mixture ratio is
regulated by the U.S. EPA and many individual
states; do not exceed the allowable washer
fluid dilution ratio limits that apply. Follow the

Selector lever positions
D Drive Selector lever position for normal vehicle oper‐
ation. All gears for forward travel are activated
automatically.
R Reverse Select only when the vehicle is stationary.
N Neutral
The vehicle may roll. Use in automatic car
washes, for example.
P Park
Select only when the vehicle is stationary. The
drive wheels are blocked.
Before exiting the vehicle, make sure that se‐
lector lever position P is set. Otherwise, the ve‐
hicle may begin to move.
Kickdown
Kickdown is used to achieve maximum driving
performance. Step on the accelerator pedal be‐
yond the resistance point at the full throttle po‐
sition.
Engaging selector lever positions
To prevent the vehicle from creeping after you
select a gear, maintain pressure on the brake
pedal until you are ready to start.
The selector lever can only be taken out of se‐
lector lever position P if the ignition is on or the
engine is running.
With the vehicle stationary, depress the brake
pedal before shifting out of selector lever posi‐
tion P or N; otherwise, the shift block will not be
deactivated and the shift command will not be
executed.
A block prevents the inadvertent switching to
selector lever position P or R or the inadvertent
change from selector lever position P.
Canceling the lock
Press unlock button on the front of the selector
lever, arrow.

▷Shift down: briefly pull left shift paddle.▷The lowest possible gear can be selected by
pulling and holding the left shift paddle.
Gears will only be shifted at appropriate engine
and road speeds, for example downshifting is
not possible if the engine speed is too high.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the current gear.
If the shift paddles on the steering wheel are
used to shift gears in automatic mode, the
transmission temporarily switches to manual
mode.
In the manual mode, after conservative driving
for a certain amount of time or if there has
been no acceleration or shifting of the shift
paddles within a certain amount of time, the
transmission switches back to automatic mode.
It is possible to switch into the automatic mode:
▷Pull and hold right shift paddle.
or▷In addition to the briefly pulled right shift
paddle, briefly pull the left shift paddle.
Displays in the instrument cluster
The selector lever position is dis‐
played, for example: P.
Manually release the transmission lock Should the selector lever be blocked in selector
lever position P despite the ignition being
turned on, the brake being depressed and the
unlock button being pressed, the transmission
lock can be manually canceled:
Before unlocking the transmission lock man‐
ually, engage the parking brake forcefully to
prevent the vehicle from rolling away.
