Climate control
Heated rear window Ü 3 42.
The preselected temperature is
automatically regulated. In the
automatic
mode the fan speed and air
distribution automatically regulate the
air flow.
The system can be manually adapted
by use of air distribution and air flow
controls. Data is shown on the Info-Display.
Setting modifications are briefly

Driving and operating
The system can also be activated at
low speed by pressing the r button.
An obstacle is indicated by buzzers.
The interval between the buzzers
becomes shorter as the vehicle gets
closer to the obstacle. When the
distance is less than 30 cm, the
buzzer is continuous. 9
Warning Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external
noise sources may cause
the system to fail to detect
obstacles. Deactivation
Deactivate the system by pressing
the r button.
The system automatically switches
itself off when the vehicle is driven
above a certain speed.

Fuel
Fuel for petrol engines
Only
use unleaded fuel that complies
with DIN EN 228.
Fuels with ethanol content greater
than 5% may only be used if the
vehicle has been specifically
developed and approved for these
fuels.
Use fuel with the recommended
octane rating 3 209. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly
increases fuel consumption. Caution
Use of fuel with too low an octane
rating could lead to uncontrolled
combustion and engine damage.
Fuel for diesel engines
Only use diesel fuel that complies
with
DIN EN 590. The fuel must have
low sulphur content (max. 50 ppm).
