Dynamic Traction Control
DTC
The concept The DTC system and the TRACTION program
are a variant of the DSC in which forward mo‐
mentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.
Deactivating/activating Dynamic
Traction Control DTC
The system and program can be deactivated/
activated via Dynamic Driving Control, refer to
page 103.

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.
Malfunction
Malfunctions are displayed via Check Control,

ble regardless of the season, using maximum
cooling or heating power if necessary, and
then maintains it.Seite 112ControlsClimate112
Online Edition for Part no. 01 40 2 954 104 - II/15

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 program
When 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.

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.
