Daytime running lamps/  
Sidelamps  
These LED lamps at the front and rear of the  
vehicle light up automatically when the engine  
starts.  
Three flashes  
►ꢀ Press briefly upwards or downwards, without  
going beyond the point of resistance; the direction  
indicators will flash 3 times.  
Never look too closely at the light beam of  
LED technology lamps - risk of serious eye  
injury!  
Parking lamps  
(Depending on version)  
They perform the following functions:  
– Daytime running lamps (lighting control stalk at  
position "AUTO" with adequate ambient light).  
– Sidelamps (lighting control stalk at position  
"AUTO" with low ambient light or "Sidelamps  
only" or "Dipped/main beam headlamps").  
Vehicle side marking by lighting the sidelamps on  
the traffic side only.  
►ꢀ Within one minute after switching off the  
ignition, operate the lighting control stalk  
upwards or downwards, depending on the side of  
the traffic (e.g. when parking on the right, push  
the lighting control stalk down to light up on the  
left).  
Direction indicators  
Travelling abroad  
This is confirmed by an audible signal and the  
lighting of the corresponding direction indicator  
lamp on the instrument panel.  
The design of the dipped beam headlamps  
allows you to drive, without any modification,  
in a country that drives on the other side of  
the road to the country in which your vehicle  
was sold.  
►ꢀ To switch off the parking lamps, return the  
lighting control stalk to the central position.  
However, for versions with DS ACTIVE LED  
VISION headlamps, the Adaptive Frontlight  
System function should not be activated in  
order to avoid dazzling drivers of oncoming  
vehicles.  
Automatic illumination of  
lamps  
►ꢀ Left or right: lower or raise the lighting control  
stalk, beyond the point of resistance.  
With the lighting control stalk in the “AUTO”  
position and if a low level of exterior brightness  
is detected by the rain/sunshine sensor, the  
sidelamps and dipped beam headlamps are  
switched on automatically, without any action on  
the part of the driver. They may also come on if  
rain is detected, at the same time as automatic  
operation of the windscreen wipers.  
If you keep the direction indicators on for  
more than 20 seconds, the volume of the  
audible signal will increase if the speed is  
above 50 mph (80 km/h).
