a short time. G
WARNING
The glass in the panorama sunroof could
break in an accident. If you are not wearing a
seat belt, there is a risk that you could be
thrown through the opening in the event of the
vehicle overturning. Therefore, always wear a
seat belt to reduce the risk of injuries.

functions may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.
i Resonance noises can occur in addition
to the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.

Hill start assist
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. G
WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
X Take your foot off the brake pedal.
The vehicle is then held for about a second.
X Pull away.
Hill start assist will not function if:
R you are pulling away on a level road or a
downhill gradient.

you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving.
There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away. General notes The ECO start/stop function switches the
