WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior. In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves
R never cover the vents or ventilation grilles
in the vehicle interior Adjusting the air vents

Driving tips General driving tips
Drive carefully and maintain a suitable dis-
tance to the vehicle in front. Avoid frequent
and sudden acceleration as well as abrupt
braking.
During partial electric drive, pulling away and
acceleration, the electric motor supports the
internal combustion engine.
During overrun in transmission position Dand
braking, the electric motor operates as an
alternator.
To reduce fuel consumption, use:
R recuperative braking (Y page 273)
R overrun mode (Y page 283) or extended
overrun mode (Y page 283)
For further information on the ECO start/stop
function, see (Y page 282).
Additional driving tips (Y page 215).
Stationary vehicle
If the vehicle is stopped, the combustion
engine is, for the most part, switched off.
Automatic climate control continues to func-
tion. The electro-mechanically assisted steer-
ing gear allows use of the power steering
