2016 MERCEDES-BENZ SL ROADSTER warning light

Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched on even during the daytime. In some countries,
operation of the headlamps varies due to legal
requirements and self-imposed obligations. Driving abroad
Symmetrical dipped-beam headlamps If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is reg-
istered, your headlamps must be switched to
symmetrical dipped beam. This prevents
oncoming traffic from being dazzled. Symmetri-
cal lights do not illuminate as large an area of the edge of the carriageway.
Convert the headlamps as close to the border aspossible before driving in these countries
(Y page 210).
Asymmetrical dipped-beam headlamps Convert the headlamps back to asymmetrical
dipped beam as soon as possible after crossing
the border (Y page 210).
If the headlamps are converted to symmetrical
dipped beam, the "motorway mode" and "exten-
ded range foglamps" functions (Intelligent Light
System) are not available. Setting the exterior lighting

General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit the
prevailing driving and weather conditions. It
offers advanced functions for improved illumi-
nation of the road surface, e.g. depending on the vehicle speed or weather conditions. The sys-
tem includes the active light function, corneringlight function, motorway mode and extended
range foglamps. The system is only active when it is dark.
You can activate or deactivate the "Intelligent
Light System" function using the on-board com-
puter (Y page 209). Exterior lighting

WARNING
Adaptive Highbeam Assist Plus does not rec-
ognise road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
Plus may not recognise road users who do
have lights, or may recognise them too late. In this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or will be activated despite the presence of
other road users. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions and switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist Plus cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist Plus is only an aid.
You are responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and traf-
fic conditions.
In particular, the detection of obstacles can be

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
G
WARNING
When AIRSCARF is switched on, very hot air
can flow from the vents in the head restraints. This could result in burns in the immediate
vicinity of the air vents. There is a risk of injury.
Reduce the heater output before it becomes
too hot.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes: R keep the air inlet grille on the bonnet and in
the engine compartment on the front-
passenger side free of blockages, such as ice,
snow or leaves
R never cover the vents or ventilation grilles in
the vehicle interior
i You can move the adjusters for the air vents
vertically or horizontally to set the direction of the airflow.
