Problems with the side windows
GWARNING
If you close a side window again immediately
after it has been blocked or reset, the side
window closes with increased or maximum
force. The reversing feature is then not active. Parts of the body could be trapped in the clos-
ing area in the process. This poses an
increased risk of injury or even fatal injury.
Make sure that no parts of the body are in the
closing area. To stop the closing process,
release the switch or push the switch again to
reopen the side window.
If you cannot completely open or close a side
window:
If there are no objects or leaves in the window
guide that prevent the sliding sunroof from clos-
ing, there has been a malfunction or the on-
board voltage has been interrupted.
XReset the side window (Ypage 83).

In the setting Standard
, no warning vibration
occurs if:
Ryou operate the turn signal in the correspond-
ing direction. In this event, the warnings are
suppressed for a certain period of time.
Ra driving safety system, such as ABS, BAS or
ESP®, intervenes or performs a control
action.
When Adaptive

warning vibration when:
Ryou accelerate hard, e.g. kickdown.
Rbrake sharply.
Ryou steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
Ryou cut the corner on a sharp bend.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system differentiates between various
conditions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, such as a high-
way.
Rthe system detects solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.

Alertness Assistant ATTENTION
ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys such as on freeways and
interstate highways. It is active in the 40 mph
(60 km/h) to 125 mph (200 km/h) range. If
ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration on
the part of the driver, it suggests taking a break.
Important safety notes
ATTENTION ASSIST is only an aid. The system
may not always detect fatigue or lapses in con-
centration until too late, or may not detect them
at all. ATTENTION ASSIST is not a substitute for
a well-rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or not
occur at all:
Rif the length of the journey is less than approx-
imately 30 minutes
Rif the road condition is poor, e.g. if the surface
is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
Rif you are predominantly driving at a speed
below 40 mph (60 km/h) or above 125 mph
(200 km/h)
Rif the time has been set incorrectly
Rin active driving situations, such as when you
change lanes or change your speed
ATTENTION ASSIST is reset and starts assessing
your attention again when you continue your
journey if:
Ryou switch off the engine
Ryou take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break
