WARNING
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your vehi-
cle and it could roll away.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and depress it before the vehicle begins to
roll.
Take your foot off the brake pedal.

The vehicle is then held for about a second.
Pull away.

engine will automatically start. The vehicle
may begin moving. There is a risk of accident.
To prevent the vehicle from accidentally pull-
ing away, do not release the brake pedal until
you want to drive on.
Do not leave the vehicle until you have
switched off the ignition and secured the vehi-
cle to prevent it from rolling away.
! Always switch the ignition off and take the
key with you when leaving the vehicle.
The ECO start/stop function switches the
engine off automatically if the vehicle stops

When pulling away again, the engine starts
automatically. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle.
The ECO start/stop function is activated each
time the engine is switched on. The system is
operational when the ¤ symbol is shown
in the multifunction display.
