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.

activated, the engine auto-stops approxi-

speed driving* using a function
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.

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.

order to facilitate traction and speed control at
low speed.

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.
