1. ARS 2-X function
ARS 2-X is a completely new type of cruise control system that

supports the driver whi le driving. How ever, ARS 2-X does not
relieve the driver of their responsibility or reduce the pleasure of
driving.

ARS 2-X is an extension of the normal cruise control function that can
not only keep the speed constant, but will automatically adjusts the
speed to the flow of the traffic in front.
The system may be operated like a normal cruise control:

- Whenever you press the accelerator, the car accelerates

- Whenever you brake, the system will switch off
The driver is relieved of routine work (such as, taking note of the

maximum speed limit, reading the speedometer, estimating the distance
from the vehicle in front, and constantly regulating these parameters with
the accelerator and brake pedals) during NORMAL DRIVING.
The driver has time to observe the traffic in front, to decide on a driving
strategy, and to react in sufficient time to critical situations. This is the
reason why driving with ARS 2-X is less tiring and is safer and far more
enjoyable.

Basic function:

• As long as the road is free in front of the vehicle, the ARS 2-X
keeps the set speed

constant.

• If the vehicle approaches a slower-moving vehicle in front, it adapts
the speed to the vehicle ahead and then maintains the selected
time-distance (in seconds) from this vehicle.

• When the road becomes clear again, the vehicle again accelerates
back to the set speed

• The set speed can be selected in 5 mph (10 km/h) increments
(irrespective of the speed at which the vehicle is currently traveling)

• The ranging cruise control includes the possibility of limited brake
actuation. This allows you to adapt the speed comfortably and
relatively quickly by use of the finger controls. The limited braking
will also prevent the vehicle from traveling unintentionally faster on
roads with a gradient.

2. Benefits to the customer

• Relaxed driving

• Less fatigue

• Driving with better anticipation

• Noticeable on every journey

• Active safety improvements thanks to driving more attentively and

with more awareness of distances

• The many benefits of the ARS 2-X can also be seen in the comments

from the assessments of drivers (see below)

• The best arguments, favoring ARS 2-X can be experienced by

DRIVING with the system

3. How drivers assess the ARS 2-X based on their own

EXPERIENCE

• I’m enthusiastic about it – I want this function!

• Very pleasant

• Helpful and stress-reducing

• I needed half an hour to get used to this completely new driving

experience.

• Before I drove with the ARS 2-X, I thought I wouldn’t need
something like that.

• I’ll never again drive too slowly. Whenever the traffic situation
permits, I’ll drive at exactly the speed I want to drive at.
