▷Shift up: pull right shift paddle.▷Shift down: pull left shift paddle.
The vehicle only shifts up or down at appropriate
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 gear 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 gearbox
components in which the gears are changed
without loss of torque.
The transmission is operated using the selector
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 58.▷Automatic throttle blip.
System limits
This transmission is equipped with an overheat‐
ing 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 engine is in‐
terrupted. You can only continue driving 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.

Adaptive light control
The concept
Adaptive light control is a variable headlamp
control system that enables dynamic illumina‐
tion of the road surface.
Depending on the steering angle and other pa‐
rameters, the light from the headlamp follows
the course of the road.
Controls
Activating
Switch position
with the ignition switched
on.
Auxiliary function:
To avoid blinding oncoming traffic, the adaptive
light control directs light towards the front pas‐
senger side when the vehicle is at a standstill.
Malfunction
Adaptive light control is malfunctioning or has
failed. Have the system checked as soon as pos‐
sible.

The selected program is displayed in the instru‐
ment cluster.
Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.
1.Hold the vehicle in place with the foot brake.2.Release the foot brake and drive away with‐
out 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 driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 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 sys‐
tems.
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 con‐
ditions make it impossible to drive at a constant
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 vehicle
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.

ating3Deactivating cruise control4Resuming a speed stored beforehand
Maintaining current speed
Push the lever, arrow 1, or pull it briefly, arrow 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 effect
is insufficient on downhill slopes, the system 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.▷Each time the lever is pressed beyond the
resistance point, the desired speed is in‐
creased by up to 5 mph/10 km/h.
The system stores and maintains the speed.

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 position, a
small amount of air is also directed toward the
windows to keep them from fogging over.
Recirculated air mode If the air outside the car has an un‐
pleasant odor or contains pollu‐
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 activated/
deactivated, refer to page 12, via a button on the
steering wheel.
Only use recirculated air mode for a limited
period
If condensation starts to form on the inside win‐
dow surfaces during operation in the recircu‐
lated air mode, you should switch it off while also
increasing the air flow rate as required. The re‐
circulated air mode should not be used contin‐
uously for lengthy periods; otherwise, the qual‐
ity of the air inside the car will gradually
deteriorate.◀
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.
Switching the system on/off Press the left button at the mini‐
mum fan speed. The blower and air
conditioner are completely
switched off and the air supply is cut off.Seite 90ControlsClimate90

In order to set the compass zones, press and
hold the adjustment button for 3‑4 seconds.
The number of the compass zone set is shown
in the display.
To change the zone setting, briefly press the
adjustment button repeatedly until the display
shows the number of the compass zone corre‐
sponding to your current location.
The compass is operational again after approx.
10 seconds.
Calibrating the digital compass
The digital compass must be calibrated in the
following situations:▷An incorrect compass direction is shown.▷The cardinal direction displayed does not
change even if the direction of travel
changes.▷Not all compass directions are shown.
Procedure
1.Make sure that there are no large metal ob‐
jects or overhead power lines in the vicinityof your vehicle and that you have enough
space to drive in a circle.2.Set the currently valid compass zone.3.Ensure that the retractable hardtop is fully
closed.4.Press the adjustment button for 6‑7 sec‐
onds to call up C. Then drive in at least one
complete circle at a maximum speed of
4 mph/7 km/h. If the calibration was suc‐
cessful, the display C is replaced with the
cardinal directions.5.Open the retractable hardtop fully and re‐
peat step 4.
Setting right-hand/left-hand steering
Your digital compass is factory-set to right-hand
or left-hand steering, in accordance with your
vehicle.

Ensure that the floor mats are securely fastened
again when they are returned after being re‐
moved, such as for cleaning.◀
Driving in wet conditions
When 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, resulting in a
reduction in the brake system efficiency.
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 54.
Downshifting in manual mode of the 7-gear
Sport automatic transmission with dual clutch,
refer to page 57.
Avoid load on the brakes
Avoid placing excessive load on the brake
system. Light but consistent brake pressure can
lead to high temperatures, brake wear and pos‐
sibly 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 contamination
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, con‐
densation water develops that exits underneath
the vehicle.
Therefore, traces of condensed water under the
vehicle are normal.
Loading Overloading the vehicle
To avoid exceeding the approved carrying
capacity of the tires, never overload the vehicle.
Overloading can lead to overheating and in‐
creases the rate at which damage develops in‐
side the tires. This could result in a sudden loss
of tire inflation pressure.◀
Secure heavy objects
Never transport unsecured heavy or hard
objects in the passenger compartment, as they
could be thrown around and pose a safety haz‐
ard to the vehicle's occupants during abrupt
braking or evasive maneuvers.◀
No fluids in the cargo area
Make sure that fluids do not leak into the
cargo area; otherwise, the vehicle may be dam‐
aged.◀

Do not lift the vehicle
Do not lift the vehicle by the tow fitting or
body and chassis parts; otherwise, damage may
result.◀
Tow bar
The tow fittings used should be on the same
side on both vehicles.
Should it prove impossible to avoid mounting
the tow bar at an offset angle, please observe
the following:▷Clearance and maneuvering capability will
be sharply limited during cornering.▷The tow bar will generate lateral forces if it
is attached offset.
Tow rope
When starting to tow the vehicle, make sure that
the tow rope is taut.
To avoid jerking and the associated stresses on
the vehicle components when towing, always
use nylon ropes or nylon straps.
Attaching the tow rope correctly
Only secure the tow rope on the tow fit‐
ting; otherwise, damage can occur when it is se‐
cured on other parts of the vehicle.◀
