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.
Mechanical steering column lock (steering lockyfLQYHKLFOHVZLWKDQ
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.

or 210 km/h (130 mphyf7KLVVSHHGUDQJHPD\GLIIHULQFHUWDLQPDUNHWV.
Radar sensor
ACC detects driving situations by means of the radar sensor at the front of the vehicle ⇒ Front 
view. The range of the radar sensor is up to approximately 120 m.
Does the vehicle have ACC?
The vehicle is equipped with ACC if you can make settings for ACC in the vehicle settings of the
Infotainment system ⇒ Vehicle settings menu.
If the vehicle has ACC, the cruise control system is not available as an independent system.

•Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road
and traffic conditions.
•Do not use the ACC in poor visibility, on steep or winding roads, on slippery road
surfaces, e.g. on snow, ice, wet roads, loose chippings, or on flooded roads.
•Never use ACC off-road or on non-surfaced roads. The ACC is designed for use on
surfaced roads only.
•ACC does not respond to stationary vehicles.
•The ACC does not react to persons, animals or vehicles crossing or approaching in the
same lane.
•Brake immediately if speed reduction by ACC is not sufficient.
•Brake immediately if a request to brake appears on the instrument cluster display.
•Brake if the vehicle starts rolling unintentionally after a request to brake.
•Be prepared to control the speed yourself at all times.

Objects that cannot be detected
•Persons
•Animals
•Stationary vehicles
•Crossing or oncoming vehicles
•Other stationary obstacles
If the message ACC ready is shown on the instrument cluster display and the vehicle in
front moves off, your vehicle will move off automatically. In some cases, the radar sensor
may be unable to detect obstacles that are located in the vehicle's path. This can result in
serious injury and accidents.
•Always check the road ahead before moving off and brake the vehicle if necessary.
WARNING

If a stationary vehicle is hidden behind a vehicle that has been detected by the adaptive cruise
control and this vehicle turns off the road or changes lane, the ACC will not react to the stationary
vehicle ⇒ Fig. 144.
Bends
The radar sensor always measures straight ahead. For this reason, vehicles may be incorrectly
detected or vehicles driving ahead not detected in tight bends ⇒ Fig. 143.
Vehicles outside the sensor range
•Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g.
motorbikes ⇒ Fig. 143.

The area monitoring system (Front
AssistyfZLWK&LW\(PHUJHQF\%UDNLQJ
System can help to avoid accidents.
Within the limits of the system, Front Assist can warn the driver about imminent collisions, prepare
the vehicle for emergency braking, assist with braking, and initiate automatic braking. The warning
time varies depending on the traffic situation and driver behaviour.
Front Assist is not a substitute for the full concentration of the driver.
Driving with Front Assist
You can cancel the automatic braking interventions of Front Assist by steering or pressing the
accelerator.
Automatic braking
Front Assist can decelerate the vehicle to a standstill. The vehicle will then not be held
permanently. Depress the brake pedal.
The brake pedal will feel harder during an automatic braking operation.
Radar sensor
Front Assist detects driving situations by means of the radar sensor at the front of the vehicle
⇒ Front view. The range of the radar sensor is up to approximately 120 m.

Functions included in the system
The City Emergency Braking System and Pedestrian Monitoring (depending on vehicle equipmentyf
are part of Front Assist and are automatically active when Front Assist is switched on.
Warning levels and braking intervention
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Distance warning
The system detects when safety is endangered by driving too close to the vehicle in front. The
warning lamp Lit up Increase the distance.
Speed range: around 65 km/h (40 mphyfWRNPKPSK\f.
Advance warning
The system detects a possible collision with a vehicle in front or a pedestrian crossing in front of the
vehicle and prepares the vehicle for possible emergency braking.
A warning tone sounds and the warning lamp Lit up Brake or take evasive action.
Speed range: around 30 km/h (20 mphyfWRNPKPSK\f.
Urgent warning
If the driver does not react to the advance warning, the system may initiate a short braking jolt in
order to draw attention to the increasing collision risk. Brake or take evasive action.
Speed range: around 30 km/h (20 mphyfWRNPKPSK\f.
Automatic braking
If the driver also does not react to the urgent warning, the vehicle can be braked automatically with
braking force that increases in several stages. The reduced speed means that it is possible to
minimise the consequences of an accident.
Speed range: around 5 km/h (3 mphyfWRNPKPSK\f.
Braking intervention
If the system detects that the driver is braking insufficiently when there is a risk of collision, the
system can increase the braking force and help prevent a collision. The braking intervention takes
place only for as long as the brake pedal is pressed hard.
Speed range: around 5 km/h (3 mphyfWRNPKPSK\f.
The intelligent technology of Front Assist cannot overcome the laws of physics, and
functions only within the limits of the system. Never let the extra convenience afforded by
Front Assist tempt you into taking risks when driving. The driver is always responsible for
braking in time.
•If Front Assist issues a warning, brake your vehicle immediately depending on the
traffic situation or avoid the obstacle.
•Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road
and traffic conditions.
•Front Assist cannot prevent accidents and serious injuries on its own.
•Front Assist can issue unnecessary warnings and carry out unwanted braking
interventions in certain complex driving situations, e.g. at traffic islands.
•Front Assist can issue unnecessary warnings and carry out unwanted braking
interventions when its function is impaired, e.g. if the radar sensor is dirty or its
position has been changed.
•Front Assist without Pedestrian Monitoring does not react to persons. In addition, the
system does not react to animals or crossing vehicles or to vehicles that are
approaching in the same lane.
•If you are unsure whether the vehicle possesses Pedestrian Monitoring, please enquire
about this at a qualified workshop before starting your journey.
•Be prepared to take over control of the vehicle yourself at all times.
