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.
Steering
The power steering is not hydraulic. It 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 starter button
The steering column will be locked if the driver door is opened and 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 vehicle key or the sensor in the door
handle.

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 clicks into place.
Insert the vehicle key into the ignition lock to unlock the steering lock. Turn the steering wheel
slightly to take the load off the steering lock mechanism. Hold the steering wheel in this position and
turn the ignition on.
Electromechanical steering
The power steering provided by the electromechanical steering system automatically adjusts to the
vehicle speed, steering wheel torque and steering wheel angle. The electromechanical steering
only functions 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 power steering in critical driving situations.
Additional steering power helps the driver when counter steering ⇒.
The intelligent Hill Descent Control technology cannot overcome the laws of physics, and
functions only within the limits of the system. Never allow the extra convenience afforded
by pull-away assist systems to tempt you into taking any risks when driving.
•Unintentional vehicle movements can cause serious injury.
•The Hill Descent Control cannot replace the full concentration of the driver.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions.
•A Hill Descent Control System may not be able to always hold the vehicle on uphill
gradients or brake it sufficiently on all slopes going downhill (e.g. if the ground is
slippery or icyyf .
WARNING
Always be prepared to brake the vehicle. Accidents and injuries could occur if this is not
ensured.
•The Hill Descent Control system is only a support function and may not be able to
brake the vehicle sufficiently in all situations when driving downhill.
•The vehicle may accelerate despite the Hill Descent Control system.
WARNING
Progressive steering
Depending on the vehicle equipment level, progressive steering can adjust the force of the steering
movement in a driving situation. Progressive steering only functions when the engine is running.
In urban driving, smaller steering movements are 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.

This chapter contains information on the followingsubjects:

⇒ Adjusting the driving profile to suit your requirements
⇒ Troubleshooting
The driving profile selection contains
factory-defined driving profiles which
have different effects on the vehicle
setup. You can also set your own
vehicle setup by means of an individual
driving profile.
Different driving profiles can be selected depending on the vehicle equipment level. The effect on
the vehicle setup in the individual driving profiles depends on the vehicle equipment.
The settings available depend on the type of drive. Vehicles with a front-wheel drive come with
ONROAD driving profiles ⇒ Selecting a driving profile (ONROADyf, while vehicles with all-wheel
If the power steering is not working, the steering wheel is difficult to turn, which makes it
difficult to steer the vehicle.
•The power steering only functions 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 lock when 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.
WARNING
The ignition of the vehicle being towed 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.

Introduction
Selecting the driving profile
•Switch on the ignition.
•Press the driving profile selection button ⇒ Fig. 128.
•Touch the function button in the Infotainment system to display additional information about
the active driving profile.
•Touch the function button for the required driving profile.
•OR: press the driving profile button ⇒ Fig. 128 again to select the next driving profile.
If the Normal driving profile is selected, the LED in the driving profile selection button will remain
switched off.
When the ignition is switched off, the set driving profile and the individual settings will remain
selected.
The driving profiles Sport and Eco will also remain selected after the ignition has been switched
off. However, settings for the engine or DSG dual clutch gearbox may switch to the Normal driving
profile when the ignition is switched back on again.
In order to reactivate the sports function, the Sport driving profile must be selected again or the
selector lever of the DSG dual clutch gearbox must be moved to S⇒ DSG dual clutch gearbox.
To reactivate the eco functions, select the Eco driving profile again.
Recommended driving situations for each driving profile
•Eco: switches the vehicle into economical mode and helps the driver to drive the vehicle in a
fuel-efficient manner. Coasting mode is available in the Eco driving profile.
•Comfort: the Comfort driving profile is available only for vehicles with adaptive chassis control
