Driving with start/stop function  
With the start/stop function, the engine  
switches off temporarily when the car has  
stopped e.g. at traffic lights or in a traffic  
queue, and then starts again when it is nee-  
ded.  
The start/stop function reduces fuel consump-  
tion, which in turn contributes to reduced  
exhaust emissions.  
The start/stop function temporarily switches  
off the engine when stationary and then  
starts it automatically when required.  
The Start/Stop function is available when the  
car is started and can be activated if certain  
conditions have been met.  
Declutch, set the gear lever in neutral  
position and release the clutch pedal - the  
engine stops automatically.  
In drive mode Comfort or Eco, the engine  
may auto-stop before the car is completely  
stationary.  
The driver display indicates when the function  
is  
With adaptive cruise control or Pilot Assist  
activated, the engine auto-stops approxi-  
mately 3 seconds after the car has stopped.  
The system makes it possible to adopt an  
environmentally-conscious driving style by  
allowing the car to engine auto-stop when  
possible.

button  
The low speed control function (LSC14) facili-  
tates and improves traction for driving off-  
road and on slippery surfaces, such as with a  
caravan on grass or a boat trailer on a launch  
ramp.  
When LSC with HDC is activated, the feel  
of the accelerator pedal and engine  
response are changed.  
There is a function button for low-speed driv-  
ing with Hill Descent Control in the centre  
display's function view unless the car was  
equipped with a drive mode button in the  
centre console.  
In a car with drive mode button*, the function  
is included in the Off Road drive mode.  
The function is adapted for off-road driving  
and driving with a trailer at low speed, up to  
approx. 40 km/h (25 mph).  
The driving mode is not designed to be  
used on public roads.

Press the Hill Descent Control button to  
Low speed control prioritises low gears and  
traction. If the car is all-wheel drive, the  
motive force is distributed evenly in order to  
provide as good traction as possible on all  
wheels and to reduce the risk of wheel spin.  
The accelerator pedal is less responsive in  
order to facilitate traction and speed control at  
low speed.

The function is deactivated when driving at  
higher speeds and must be reactivated at a  
lower speed, if required.

> An indicator in the button illuminates  
when the function is activated.  
The function is activated together with hill  
descent control, (HDC15) which means that  
speed down steep hills can be controlled with  
the accelerator pedal, reducing the need to  
use the brake pedal. The system facilitates a  
low and even speed while driving on steep  
downhill gradients.
