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.
Cruise controlThe 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.

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.▷Each time the lever is pressed beyond the
resistance point, the desired speed is in‐
creased by up to 5 mph/10 km/h.Seite 103Driving comfortControls103

and hold until the desired speed is reached.
Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, and hold until the desired speed is
reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance
point or beyond, arrow 2, until the desired
speed is displayed.▷Each time the lever is pulled to the resist‐
ance point, the desired speed is decreased
by approx. 1 mph/1 km/h.▷Each time the lever is pulled beyond the
resistance point, the desired speed is re‐
duced by up to 5 mph or 10 km/h until the
minimum speed of 20 mph/30 km/h is ach‐
ieved.
The system stores and maintains the speed.
Interrupting the system
Push the lever upwards or downwards, ar‐
row 3.
The displays in the speedometer change color.
In addition, the system is automatically inter‐
rupted in the following situations:
▷When the brakes are applied.▷In cars with manual transmission, when
gears are shifted very slowly or if neutral is
engaged.▷In cars with Sport automatic transmission,
when transmission position N is engaged.▷When DTC is activated or DSC is deacti‐
vated.▷When DSC or ABS is intervening.
Cruise control is not deactivated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the stored speed is achieved
again and maintained.

Park Distance Control PDC
The concept PDC supports you when parking.
You are alerted that you are slowly approach‐
ing an object behind the vehicle and, if equip‐
ped accordingly, in front of the vehicle by:▷Signal tones.▷A visual display.
Measurement
Measurements are made by ultrasound sen‐
sors in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷By the front sensors and two rear corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
System limits
Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an acci‐
dent could result from road users or objects
located outside of the PDC detection range.
Loud noises from outside and inside the vehi‐
cle may prevent you from hearing the PDC's
signal tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physi‐
cal limits of ultrasonic measurement, for in‐
stance:▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With low objects.▷With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before
or after a continuous tone sounds.
High, protruding objects such as ledges may
not be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground ga‐
rages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
Engage reverse gear with the engine running
or the ignition switched on.

Switching off automatically when
driving forward
The system switches off when a certain dis‐
tance or speed is exceeded.
Switch on the system again if necessary.
Signal tonesWhen approaching an object, an intermittent
tone is sounded that indicates the position of
the object. For example, if an object is de‐
tected to the left rear of the vehicle, a signal
tone sounds from the left rear speaker.
The shorter the distance to the object be‐
comes, the shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
If objects are located both in front of and be‐
hind the vehicle, an alternating continuous sig‐
nal is sounded.
The intermittent tone is interrupted after ap‐
prox. 3 seconds:▷If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.▷If moving parallel to a wall.
The signal tone is switched off:
▷When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.▷When transmission position P is engaged.
Volume
You can set the volume of the PDC signal, refer
to page 161.
The setting is stored for the remote control
currently in use.
Visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis‐
play before a signal sounds. The display ap‐
pears as soon as PDC is switched on.
Malfunction The indicator lamp in the instrument
cluster comes on. PDC has failed.
A message appears on the Control Display.
Have the system checked.
To ensure full operability:▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and
maintain a distance of at least 12 in/30 cm.Seite 106ControlsDriving comfort106

To give the automatic climate control enough
time to achieve the set temperature, do not
switch between different temperature settings
in quick succession.
Maximum heating power can be obtained with
the highest setting, regardless of the external
temperature.
The lowest setting effects continuous cooling.
Switching the cooling function on and
off
The cooling function cools and
dehumidifies the incoming air be‐
fore reheating it as required, ac‐ cording to the temperature set‐
ting. This function is only available
while the engine is running.
The cooling function helps to prevent conden‐
sation on the windows or to remove it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is switched on automati‐
cally with the AUTO program.
Maximum cooling The air is cooled as quickly as
possible with the engine running.
The automatic climate control goes into recir‐
culated air mode at the lowest temperature. Air
flows at maximum rate from the vents for the
upper body area. You should therefore open
the vents for maximum cooling.
AUTO program
The AUTO program automatically adjusts the
air distribution to the windshield and side win‐
dows, toward the upper body area, and into the
footwell and knee area.
The air flow rate and air distribution, in addition
to your temperature specifications, will be
adapted to outside influences as a result ofseasonal changes, e.g., sunlight or window
condensation.
The cooling function is switched on automati‐
cally with the AUTO program.
Switching on/off Press the button.
Manual air distribution and air flow
rate are activated when the AUTO program is
deactivated.
AUTO program climate level
The climate levels can be used to vary the in‐
tensity when the AUTO program is switched
on. For example, air flow is adjusted automati‐
cally to optimize climate control.
When the AUTO program is
switched on, the climate level of
the AUTO program can be se‐
lected using the buttons for controlling the
manual air flow rate.
The selected climate level is displayed by an
LED.
Convertible programWhen the hardtop is open, the convertible pro‐
gram is activated as well. In the convertible
program, the automatic climate control is opti‐
mized for driving with the hardtop open. In ad‐
dition, the air flow rate is increased as vehicle
speed increases.
The effectiveness of the convertible program
can be enhanced considerably by installing the
wind deflector.
Adjusting air flow rate manually Press the left side of the button to
reduce air flow. Press the right
side of the button to increase it.
The air volume may be reduced automatically
to save battery power. The display remains the
same.Seite 111ClimateControls111

the interior.
This function can be switched on
using the right-hand button under
the following conditions:▷Up to 15 minutes after switching off the
engine.▷When the engine is warm.▷With sufficient battery voltage.▷At an external temperature under
77 ℉/25 ℃.
The middle LED is lit when the function is on.
Automatic recirculated air mode/
recirculated air mode
Switch on the desired operating
mode by pressing this button re‐
peatedly:
▷LED off: outside air flows in
continuously.▷Left LED on, automatic recirculated air
control: a sensor detects pollutants in the
outside air. If necessary, the system blocks
the supply of outside air and recirculates
the inside air. As soon as the concentration
of pollutants in the outside air has de‐
creased sufficiently, the system automati‐
cally switches back to outside air supply.▷Right LED on, recirculated air mode: the
supply of outside air into the vehicle is per‐manently blocked. The system then recir‐
culates the air currently within the vehicle.
Only use recirculated air mode for a lim‐ ited period
If condensation starts to form on the inside
window surfaces during operation in the recir‐
culated air mode, you should switch it off while
also increasing the air flow rate as required.
The recirculated air mode should not be used
for an extended period of time, as the air qual‐
ity inside the vehicle deteriorates steadily.◀
Defrosting and defogging windows Quickly removes ice and conden‐
sation from the windshield and
front side windows.
For this purpose, also switch on the cooling
function.
