Solar panel*
A solar panel is available in combination
with the panorama sliding / pop-up roof.
The solar cells convert natural light into
electrical energy. When the engine is
switched off, the energy generated auto-
matically switches on the ventilation fan.
The constant air flow creates a cooler tem-
perature for cars parked in the sunlight.
The air flow depends on the intensity of the
solar radiation. The ventilation starts two
minutes after switching off the engine.

If Distronic is activated, one or two seg-
ments come on around the set speed.1Segments
If Distronic detects a vehicle directly
ahead, the segments from the speed of the
vehicle ahead to the set speed come on.
If Distronic calculates that there is a dan-
ger of collision:
The DTR warning lampl in the in-
strument cluster comes on red.
An intermittent warning sounds.
Immediately brake the vehicle to avoid
a collision.Under no circumstances should the
driver await the intermittent warning
sound before braking. See the fallow-
ing warning note.
The intermittent warning sound ceases
and the red DTR warning lampl
goes out when the necessary distance
to the vehicle ahead is again estab-
lished.
iThe vehicle speed displayed on the
speedometer can briefly vary from the
speed setting on the Distronic system.

Driving systems
Distronic menu in the control system
In the Distronic menu you can read the cur-
rent settings for Distronic. What appears in
the display depends on whether Distronic
and the distance warning function are
turned on or off.
Press buttonè orÿ repeatedly
until you see one of the following dis-
plays.
Warning!
G
An intermittent warning sounds and the
DTR warning lamp in the instrument cluster
is illuminated if the Distronic system calcu-
lates that the distance to the vehicle ahead
and your vehicle’s current speed indicate
that Distronic will not be capable of slowing
the vehicle sufficiently to maintain the pre-
set following distance, which creates a dan-
ger of a collision.
Immediately brake the vehicle to increase
the distance to the vehicle in front of you.
The warning sound is intended as a final cau-
tion that you have not interceded with your
own braking inputs to avoid a potentially
dangerous situation. Do not wait for the op-
eration of the warning signal to intercede
with your own braking, as that will result in
potentially dangerous emergency braking
which will not always result in an impact be-
ing avoided.
Tailgating increases the risk of an accident.
Warning!
G
Distronic brakes your vehicle with a maxi-
mum deceleration of 6.5 ft / s
2 (2 m / s
2).
This corresponds to about 20% of the maxi-
mum deceleration ability of your vehicle.
Distronic brakes the vehicle in an effort to
restore the preset distance or to maintain
the speed. The brake pedal is automatically
applied as this happens which results in the
brake pedal moving.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the Distronic system.
Do not place your foot under the brake pedal
– your foot could become caught.
