engine MERCEDES-BENZ S-Class COUPE 2017 C217 Manual Online

When ATTENTION ASSIST is deactivated, the
00D7symbol 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:TakeaBreak!.
In addition to the message shown in the multi-
function display, you will then hear a warning
tone.
XIf necessary, take a break.
XConfirm the message by pressing the 0076
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you do
not take a break and ATTENTION ASSIST con-
tinues to detect increasing lapses in concentra-
tion, you will be warned again after 15 minutes
at the earliest. This will only happen if ATTEN-
TION ASSIST still detects typical indicators of
fatigue or increasing lapses in concentration.
If a warning is given in the multifunction display,
the multimedia system offers a service station
search. You can select a service station and
navigation to this service station will then begin.
This function can be activated and deactivated
in the multimedia system.
Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum speed
permitted to the driver in the instrument cluster.
The data and general traffic regulations stored in
the navigation system are used to determine the
current speed limit.
Traffic Sign Assist is a map-based system, and
for this reason, traffic signs put up temporarily
(e.g. near roadworks) are not detected. There is also no display for changing traffic signs.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are also
shown. The sign indicating the end of a restriction only
appears with the restriction in the instrument
cluster when:
Rthe regulation must be observed with the
restriction, or
RTraffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the avail-
able sources, no speed limit appears in the
instrument cluster either.
Traffic Sign Assist is not available in all coun-
tries. In this case, display 0043appears in the
assistance graphic (
Ypage 197).
Important safety notes
Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits. Traffic
signs always have priority over the Traffic Sign
Assist display.
The system may be either functionally impaired
or temporarily unavailable if the information in
the digital street map of the navigation system is
incorrect or out of date.
Activating Traffic Sign Assist
XActivate the Traffic Sign Assist display using
the on-board computer (Ypage 198).
If you have activated the Traffic Sign Assist dis-
play in the on-board computer, the traffic regu-
lations (speed limits and overtaking restrictions)
appear in the instrument cluster for five seconds in each case. The wrong-way warning and the
traffic sign display for speed limits and overtak-
ing restrictions remain active even when the
display has been deactivated.
176Driving systems
Driving and parking

The system does not detect:
Rsmaller animals, e.g. dogs and cats
Ranimals whose silhouette is not clearly rec-
ognizable
When detected, animals are marked with small
color frame corners. In contrast to pedestrian
recognition, there is no separate readiness sym-
bol in the multifunction display.
Activating/deactivating Night View
Assist Plus
Activation conditions
You can only activate Night View Assist Plus if all
of the following conditions are met:
Rthe ignition is switched on (Ypage 121) or the
engine has been started.
Rthe light switch is in the 0058or0058 posi-
tion.
Rreverse gear has not been engaged.
Activating/deactivating
XPress button 0043.
If Night View Assist Plus is activated, the
Night View Assist Plus display is shown in the multifunction display.
The infrared headlamps only switch on in the
dark from speeds of approximately 6 mph
(10 km/h) . This means that you do not have the
full visual range while the vehicle is stationary
and cannot check whether Night View Assist
Plus is working. The infrared headlamps are
deactivated at speeds below 3 mph (5 km/h).
The Night View image continues to be displayed
until you deactivate it by pressing button 0043.
Automatic activation
You can select theNightViewAssistAuto‐matic Activationoption via the Night View
Assist menu. The pedestrian and animal search function remains active even when the Night
View image is not displayed. In the dark, in unlit
surroundings and at speeds of more than
60 km/h, the Night View image is automatically
displayed in the multifunction display as soon as
pedestrians or animals are detected.
XIn the assistance menu, select automatic acti-
vation of Night View Assist Plus
(
Ypage 198).
Spotlight function
General notes
Under certain conditions, the spotlight function
uses the headlamps to flash at detected pedes- trians.
The spotlight function is only active if:
Rpedestrian recognition is active
Rthe road surface is not lit
Rthe driving speed is at least 40 mph
(60 km/h)
Rthe "Adaptive Highbeam Assist PLUS" func-
tion is activated (Ypage 107).
The spotlight function is not active or is active
only to a limited extent if:
Ryou are driving in city traffic
Rthere are pedestrians located in the area of an
oncoming vehicle or a vehicle in front
Activating the spotlight function
The pedestrian detection with spotlight function is running the background. If the prerequisites
are met, the spotlight function uses the head-
lamps to flash four short pulses at a pedestrian
detected on or near to the road.
XIn the light menu, select the spotlight function
of Night View Assist Plus (Ypage 201).
The spotlight function does not flash at animals.

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 above 257 ‡
(125 †) do not drive any further. The engine
will otherwise be damaged.
The coolant temperature gauge is in the lower
section of the tachometer (
Ypage 34).
Under normal operating conditions and with the
specified coolant level, the coolant temperature
may rise to 255 ‡ (124 †).
