Read the "Important safety notes" section
(Y page 66). G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 250) as well as display
messages (Y page 219). ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety and
offers increased braking comfort. In addition to
the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 172) and hill start
assist (Y page 136). STEER CONTROL

noticeable steering force to the steering wheel
in the direction required for vehicle stabilisation.
This steering support is provided in particular if:

Important safety notes
G
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
i Optimal climate control function is achieved
by opening the air vents fully and setting the
adjusters to the middle position. 130

When pulling away again, the engine starts auto-
matically. The ECO start/stop function thereby
helps you to reduce the fuel consumption and
emissions of your vehicle.
