Problems with the panorama roof with power tilt/sliding panel
GWARNING
If you do not reset the sliding sunroof after a malfunction or voltage supply interruption, then the

maximum force. Parts of the body could be trapped in the closing area in the process. This poses an increased risk of injury or even fatal injury.
In such or similar situations always make sure that no parts of the body are in the closing area.
Always reset the sliding sunroof after a malfunction or voltage supply interruption.
!If the sliding sunroof still cannot be opened or closed as a result of a malfunction, contact a
qualified specialist workshop.

Electrolyte may escape if the glass in an auto-
matic anti-glare mirror breaks. The electrolyte
is harmful and causes irritation. It must not
come into contact with your skin, eyes, res-
piratory organs or clothing or be swallowed.
There is a risk of injury.
If you come into contact with the electrolyte,
observe the following:
RRinse off the electrolyte from your skin
immediately with water.
RImmediately rinse the electrolyte out of
your eyes thoroughly with clean water.
RIf the electrolyte is swallowed, immediately
rinse your mouth out thoroughly. Do not
induce vomiting.
RIf electrolyte comes into contact with your
skin or hair or is swallowed, seek medical
attention immediately.
RImmediately change out of clothing which
has come into contact with electrolyte.
RIf an allergic reaction occurs, seek medical
attention immediately.
The "Automatic anti-glare mirrors" function is
only available if the vehicle is equipped with the
"Mirrors package".

(200 km/h) range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes
ATTENTION ASSIST is only an aid to the driver. It
might not always recognize fatigue or increasinginattentiveness in time or fail to recognize them
at all. The system 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 slower than
37 mph (60 km/h) or faster than 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 when you continue
your journey and starts assessing your tiredness
again 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
Displaying the attention level
You can have current status information dis-
played in the assistance menu (Ypage 182) of
the on-board computer.
XSelect the Assistance display for Attention
Assist using the on-board computer
(
Ypage 182).
The following information is displayed:
RLength of the journey since the last break.
RThe AttentionLeveldetermined by ATTEN-
TION ASSIST, displayed in a bar display in five
levels from high to low
RIf ATTENTION ASSIST is unable to calculate
the attention level and cannot output a warn-
ing, the System Passive
message appears.
The bar display then changes the display,
such as when you are driving at a speed below
37 mph (60 km/h) or above 124 mph
(200 km/h).
Activating ATTENTION ASSIST
XActivate ATTENTION ASSIST using the on-
board computer (Ypage 183).
The system determines the attention level of
the driver depending on the setting selected:
Standard
selected: the sensitivity with which
the system determines the attention level is set
to normal.
Sensitive
selected: the sensitivity is set
higher. The attention level detected by Attention
Assist is adapted accordingly and the driver is
warned earlier.
When ATTENTION ASSIST is deactivated, the
é symbol appears in the multifunction dis-
play in the assistance graphic display.
When ATTENTION ASSIST has been deactivated,
it is automatically reactivated after the engine
has been stopped. The sensitivity selected cor-
responds to the last selection activated (stand-
ard/sensitive).
Warning in the multifunction display
If fatigue or increasing lapses in concentration
are detected, a warning appears in the multi-
function display: ATTENTION ASSIST
Take aBreak!.
In addition to the message shown in the multi-
function display, you will then hear a warning
tone.

Coolant temperature gauge
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
!A display message is shown if the coolant
temperature is too high.
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The engine
will otherwise be damaged.
The coolant temperature gage is in the instru-
ment cluster on the right-hand side (
Ypage 32).
The Hmarking in the coolant temperature gauge
corresponds to a coolant temperature of
approximately 248 ‡ (120 †).
Under normal operating conditions and at the
correct coolant level, the coolant temperature
gauge may rise to the Hmarking.
