Traction Control system
The Traction Control system (TC) is a
component of the Electronic Stability
Control (ESC) 3 175.
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational after each engine
start as soon as the control indicator
b extinguishes.
When TC operates b flashes.

signals for the front and rear
monitoring areas, each with a
different tone frequency. The signal
for front obstacles sounds via the
front speakers, for rear obstacles it
sounds from the rear of the vehicle.

row of parked cars is 1.8 metres.

200Driving and operating
Functionality
When the vehicle passes a row of
cars and the system is activated, the
advanced parking assist system
begins searching for a suitable
parking slot. When a suitable slot is
detected, a visual feedback on the
Driver Information Centre and an
acoustic signal are given.
If the driver does not stop the vehicle
within 10 metres after a parking slot is
proposed, the system starts to search for another suitable parking slot.
The parking slot suggestion of the
system is accepted when the vehicle
is stopped by the driver within
10 metres after the "Stop" message is
given. The system calculates the
optimal route into the parking slot.
Then it manoeuvres the driver into the slot by giving detailed instructions.The instructions in the display show:
■ a hint when driving faster than 30 km/h,
■ the demand to stop the vehicle, when a parking slot is detected,
■ the direction of driving during the parking manoeuvre,
■ the steering wheel position during parking,
■ for some of the instructions a progress bar is shown.

Driving and operating201
A successful parking manoeuvre is
indicated by the End position symbol.
Always pay attention to the sound of
the front-rear parking assist.
Continuous sound means that the
distance to an obstacle is less than
approx. 30 cm.
Changing the parking side
The system is configured to detect
parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
indicator to the driver side for the
duration of searching.
As soon as turn indicator is switched
off, the system searches for parking
slots on the passenger side again.
Display priorities
After activating the advanced parking assist, a message appears in the
Driver Information Centre. Advanced
parking assist indication in the Driver
Information Centre can be inhibited
