old the vehicle on the gradient in all situations or brake it
sufficiently on all slopes going downhill (e.g. if the ground is slippery or icy).
WARNING
Always be prepared to brake the vehicle. Accidents and injuries could occur if you are not prepared
to brake.
The downhill speed control is only a support function and may not be able to brake the vehicle
sufficiently in all situations when driving downhill.
The vehicle may become faster despite the downhill speed control being in operation.
Steering
Information on steering
The steering should be locked every time you leave the vehicle to make it more difficult for the
vehicle to be stolen.
The steering
The power steering is not hydraulic, but is an electromechanical system. The advantage of this
steering system is that no hydraulic hoses, hydraulic oil, pumps, filter or other parts are required.
The electromechanical system reduces fuel consumption. A hydraulic system requires constant oil
pressure in the system, whereas an electromechanical steering system only needs an energy supply
while steering.
In vehicles with driving profile selection, the selected driving profile can affect the behaviour of the
power steering Driving profile selection and 4MOTION Active Control
Electronic steering column lock in vehicles with a starter button
The steering column will be locked if the driver door is opened when the ignition is switched off. For
this, the vehicle should be stationary and, if necessary, the gear selector lever should be in position
P.
If the ignition is not switched off until after the driver door is opened, the electronic steering column
will only be locked when the vehicle is locked using the sensor in the door handle or the vehicle key.
Mechanical steering column lock (steering lock) in vehicles with an ignition lock
The steering column is locked if the vehicle key is removed from the ignition lock when the vehicle is
stationary. Turn the steering wheel slightly until the steering lock audibly engages.
Insert the vehicle key into the ignition lock to unlock the steering lock. Turn the steering wheel
slightly to relieve the load on the steering lock mechanism. Hold the steering wheel in this position
and turn the ignition on.
Electromechanical steering
the vehicle speed, steering wheel torque and steering wheel angle. The electromechanical steering
functions only when the engine is running.
You will need considerably more strength than normal to steer the vehicle if the power steering is
reduced or has failed completely.
Counter steering assistance
Counter steering assistance provides the driver with steering assistance in critical driving situations.
Additional steering forces assist the driver when counter steering
Progressive steering
Depending on the vehicle equipment level, progressive steering can adjust the steering response in a
driving situation. Progressive steering functions only when the engine is running.
In urban traffic, less steering input is required when parking, manoeuvring, or turning sharply.
When driving on country roads or on the motorway, the progressive steering provides a more
sporty, direct steering response, and a dynamic feel.
WARNING
If the power steering is not working, the steering wheel is difficult to turn, which makes it difficult to
steer the vehicle.
Depending on the vehicle equipment level, the power steering functions only when the engine is
running.
Never allow the vehicle to roll if the engine is switched off.
Never remove the vehicle key from the ignition if the vehicle is in motion. The steering column lock
may be activated and it will no longer be possible to steer the vehicle.
WARNING
In conjunction with the ESC, counter steering assistance provides the driver with assistance when
steering in critical driving situations. The driver must steer the vehicle at all times. Counter steering
assistance does not steer the vehicle.
NOTICE
When the vehicle is towed, the ignition must be switched on to prevent the steering wheel from
locking, and so that the turn signals, horn, wipers and window washer system can be used.

Additional points to note on uphill and downhill gradients
Before switching off the engine, turn the steering wheel so that the front wheels will roll against the
kerb if the parked vehicle starts to move.
When facing downhill, turn the wheels so that they face the kerb.
When facing uphill, turn the wheels so that they face the centre of the road.
WARNING
The components of the exhaust system become very hot. This can cause fires and serious injuries.
Never park the vehicle where parts of the exhaust system can come into contact with inflammable
material underneath the vehicle, e.g. undergrowth, leaves, dry grass, spilt fuel, oil etc.
WARNING
The vehicle may roll away if you leave and park the vehicle incorrectly. This can cause accidents and
serious injuries.
Ensure that the electronic parking brake is switched on before you leave the vehicle and the
indicator lamp in the instrument cluster lights up red after you switch off the ignition.
Never remove the vehicle key from the ignition if the vehicle is in motion. The steering lock may be
activated and you will no longer be able to steer or control the vehicle.
Never leave children or people requiring assistance alone in the vehicle. They could switch off the
electronic parking brake, or move the selector lever or gearshift lever, and thus set the vehicle in
motion.
Always take all vehicle keys with you every time you leave the vehicle. The engine can be started and
electrical equipment such as the window controls can be operated. This can cause serious injury.
Never leave children or people requiring assistance alone in the vehicle. They could become trapped
in the vehicle in an emergency and may not be able to get themselves to safety. For example, locked
vehicles may be subjected to very high or very low temperatures depending on the season. This can
cause serious injuries and illness or fatalities, especially in the case of small children.
NOTICE
Objects that protrude from the ground can damage the bumper and other components when
parking the vehicle or driving out of a parking space. Always take care when driving into parking
spaces with high kerbs or fixed boundaries. Stop before the wheels touch the fixed boundaries or
kerbs.
