▷If the shift paddles are not used and the ve‐
hicle is not accelerated for a certain time,
the system switches back into automatic
mode if the selector lever is in transmission
position D.▷Shift up: pull right shift paddle.▷Shift down: pull left shift paddle.
The vehicle only shifts up or down at appropri‐
ate engine and road speeds, e.g., it does not
shift down if the engine speed is too high.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the current gear.
Displays in the instrument cluster
The transmission position is displayed and the
engaged gear, such as M4, is displayed in
manual mode.
7-gear Sport automatic
transmission with dual clutch
The concept This transmission is an automated manual
transmission with two clutches and two gear‐
box components in which the gears are
changed without loss of torque.
The transmission is operated using the selec‐
tor lever and two shift paddles on the steering
wheel.
Functions:▷Choice of manual or automatic operation:
manual mode or Drive mode.▷Automatic downshifting and protection
against selecting the wrong gear, even in
manual mode.▷Acceleration assistant, Launch Control, re‐
fer to page 71.▷Automatic throttle blip.
System limits
This transmission is equipped with an over‐
heating protection system that protects the
clutches against extremely high loads.
The indicator lamp lights up yellow if
the transmission becomes too warm.
Avoid high engine loads and driving
off frequently.
If the transmission overheats, the indicator
lamp lights up red and power flow to the en‐
gine is interrupted. You can only continue driv‐
ing after the transmission has cooled down.
Avoid driving off frequently with high accelera‐
tion and do not hold the vehicle on inclines by
depressing the accelerator lightly; otherwise,
the transmission may overheat.

Activating COMFORTPress the button repeatedly until
COMFORT is selected in the instru‐
ment cluster.
Displays in the instrument cluster
The selected program is displayed in the in‐
strument cluster.
Drive-off assistant
This system supports driving away on gradi‐
ents. The parking brake is not required.
1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive away
without delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin
rolling back.◀
Servotronic
The concept
The Servotronic varies the steering force re‐
quired to turn the wheels depending on the
speed at which you are driving. Power steering
provides strong support at low speeds, which
means that little effort is needed to turn the
wheels. Power steering support lessens as
your speed increases.
The system works automatically.

Driving comfortVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
Cruise control The concept
Cruise control is available for use at speeds of
approx. 20 mph/30 km/h and higher. The car
then stores and maintains the speed that you
specify using the lever on the steering column.
In order to maintain the specified speed, the
system brakes the vehicle when the engine
braking effect is insufficient on downhill gradi‐
ents.
Do not use cruise control
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, for instance:▷On curvy roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀
Manual transmission
You can shift gears while cruise control is acti‐
vated. An indicator lamp notifies you that you
should shift gears when you drive for an ex‐
tended period at very high or very low engine
speeds, or the system is deactivated.

ating2Storing and maintaining speed or deceler‐
ating3Deactivating cruise control4Resuming a speed stored beforehand
Maintaining current speed
Push the lever, arrow 1, or pull it briefly, ar‐
row 2.
The car's current speed is stored and main‐
tained. It is displayed on the speedometer and briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking ef‐
fect is insufficient on downhill slopes, the sys‐
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow 1, until the desired
speed is reached.
▷Each time the lever is pressed to the point
of resistance, the desired speed increases
by approx. 1 mph/1 km/h.Seite 105Driving comfortControls105

tants, shut off the supply to the interior of the
car temporarily. The system then recirculates
the air currently within the vehicle.
The recirculated air mode can also be acti‐
vated/deactivated, refer to page 14, via a but‐
ton on the steering wheel.
Air volume Press the corresponding button.
The higher the rate, the more ef‐
fective the heating or cooling will
be.
The air flow rate may be reduced or the blower
may be switched off entirely to save on battery
power.
Vent settings Direct the flow of air to the win‐
dows
, to the upper body area
, or to the knee area and foot‐
well
. Intermediate positions
are possible. In the 6 o'clock posi‐
tion, a small amount of air is also directed to‐
ward the windows to keep them from fogging
over.

Objects in the area around the pedalsNo objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly fixed in
place.
Ensure that the floor mats are securely fas‐
tened again when they are returned after being
removed, such as for cleaning.◀
Driving in wet conditionsWhen roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles.
Ensure that this action does not endanger
other road users.
The heat generated in this process helps dry
the brake discs and pads.
In this way braking efficiency will be available
when you need it.
Hills
Drive long or steep downhill gradients in the
gear in which the least braking is required.
Otherwise, the brake system may overheat, re‐
sulting in a reduction in the brake system effi‐
ciency.
You can increase the engine's braking effect
by shifting down, going all the way to first gear,
if necessary.
Downshifting in manual mode of the 8-gear
Sport automatic transmission, refer to
page 67.
Downshifting in manual mode of the 7-gear
Sport automatic transmission with dual clutch,
refer to page 70.Avoid load on the brakes
Avoid placing excessive load on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brake wear
and possibly even brake failure.◀
Do not drive in neutral
Never drive with the transmission in neu‐
tral, with the engine switched off or with the
clutch depressed; otherwise, you will have nei‐
ther the braking action of the engine or nor its
power assistance when braking or steering.◀
Brake disc corrosion Corrosion on the brake discs and contamina‐
tion on the brake pads are furthered by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.
Corrosion occurs when the minimum pressure
that must be exerted by the pads during brake
applications to clean the discs is not reached.
Should corrosion form on the brake discs, the
brakes will tend to respond with a pulsating ef‐
fect that generally cannot be corrected.
Condensation under the parked
vehicle
When using the automatic climate control,
condensation water develops that exits under‐
neath the vehicle.
Therefore, traces of condensed water under
the vehicle are normal.
Loading Overloading the vehicle
To avoid exceeding the approved carry‐
ing capacity of the tires, never overload the ve‐
hicle. Overloading can lead to overheating and
increases the rate at which damage develops
