Safety

When the hazard warning lights are switched on, for example if you are being towed, you can still
indicate a change in direction or lane change by operating the turn signal. The hazard warning lights
will be interrupted temporarily.
Switch on the hazard warning lights, e.g. in the following situations:
When traffic ahead suddenly starts moving more slowly or you reach the tail end of a traffic jam to
warn vehicles behind you.
There is an emergency situation.
The vehicle has broken down.
When tow-starting or towing.
Always follow local regulations on the use of the hazard warning lights.
If the hazard warning lights are not working, you must use an alternative method of drawing
attention to the broken-down vehicle. This method must comply with traffic legislation.

WARNING
Any broken-down vehicle poses a high accident risk for the vehicle occupants and for other road
users.
Stop the vehicle as soon as possible and when safe to do so.
Park the vehicle at a safe distance from moving traffic.
Switch on the hazard warning lights.
Never leave other persons alone in the vehicle, particularly children or people requiring assistance.
This applies in particular when the doors are locked. People locked in the vehicle may be subjected
to very high or very low temperatures.

WARNING
Ignoring any of the items on this important safety checklist can lead to accidents and severe injuries.
Always follow the instructions in the checklist and observe the general safety procedures.

WARNING
The components of the exhaust system become very hot. This can cause fires and serious injuries.
Park the vehicle so that no part of the exhaust system can come into contact with any inflammable
material underneath the vehicle, e.g. dry grass, fuel.

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 radar sensor has a range of up to approximately 120 m.
Functions included in the system
The City Emergency Braking System and Pedestrian Monitoring (depending on vehicle equipment)
are part of Front Assist and are automatically active when Front Assist is switched on.

WARNING
The intelligent technology used in 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 safety 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 to vehicles that are crossing or approaching in the same lane.
If you are unsure whether your 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.
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 lights up. Increase the distance.
Speed range: around 65 km/h (40 mph) to 250 km/h (155 mph).
Advance warning

Objects that cannot be detected
Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g. vehicles
that are driving offset to your vehicle or motorbikes.
Vehicles that change into your lane directly in front of your vehicle.
Vehicles with bodies or attachments that project beyond the vehicle.
Oncoming vehicles or vehicles crossing your path.
Pedestrians who are stationary, moving towards the vehicle or moving in the same direction as the
vehicle.
Function limitations
In tight bends.
Driving in heavy rain, snow or heavy spray.
Driving in multi-storey car parks.
Driving on roads with embedded metal objects, e.g. railway tracks.
Reversing.
If TCS is switched off manually.
If ESC is taking corrective action.
If the radar sensor is dirty or covered.
If there is a fault in several brake lights on the vehicle or on a trailer with an electrical connection to
the vehicle ⇒  .
If the vehicle accelerates hard or the accelerator is fully depressed.
In complex driving situations, e.g. at traffic islands.
In unclear traffic situations, e.g. vehicles ahead are braking heavily or turning off.
If there is a fault in Front Assist.
Switching off Front Assist
If the vehicle is used in a capacity other than driving in normal traffic, e.g. offroad.
If the vehicle is being towed or is loaded onto another vehicle.
If the radar sensor is covered temporarily by add-on parts, e.g. auxiliary headlights.
If the radar sensor is faulty.
After external force on the radar sensor, e.g. after a frontal collision.
In the event of multiple unwanted interventions.

If the problem persists, switch off Front Assist and go to a qualified workshop.
Lane keeping system (Lane Assist)
Introduction
This chapter contains information on the followingsubjects:
⇒ Driving with the lane keeping system 
⇒ Troubleshooting 
The lane keeping system (Lane Assist) helps the driver stay in lane.
Using a camera in the windscreen, the lane departure warning system detects lane markings on the
road. If your vehicle moves too close to a recognised lane marking, the system will warn the driver
with a corrective steering intervention. The corrective steering intervention can be overridden by
the driver at any time.
Adaptive lane guidance (depending on vehicle equipment)
The adaptive lane guidance system detects the preferred position in a lane and keeps the vehicle in
this position.
Adaptive lane guidance is switched on and off in the Driver assistance menu in the Infotainment
system ⇒ Vehicle settings menu .
System limits
Use the lane keeping system only on motorways and good main roads.
The system is not active under the following conditions:
The lane keeping system has not detected any lane markings.

WARNING
The intelligent technology used in the lane keeping system cannot overcome the laws of physics, and
functions only within the limits of the system. Always take care when using the lane departure
warning system otherwise you could cause accidents or injuries. The system is not a substitute for
the full concentration of the driver.
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic
conditions.
Your hands should always be on the steering wheel so that you can steer at any time. The driver is
always responsible for staying in lane.
The lane keeping system cannot recognise all lane markings. Poor road surfaces, road structures or
objects could be recognised incorrectly as lane markings by the lane keeping system. The lane
keeping system should be switched off immediately in these situations.
Follow the information on the instrument cluster display and respond according to the commands.

Always pay close attention to the surroundings of the vehicle.
If the camera's field of view is dirty, covered or damaged, the function of the lane keeping system
may be impaired.

Some settings can be saved in the user accounts of the personalisation function and can therefore
change automatically when the user account is changed ⇒ Personalisation .
Driving with the lane keeping system

Fig. 123 On the instrument cluster display: lane keeping system displays.
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Switching the lane keeping system on and off
Using the button for the driver assist systems, select the corresponding menu option ⇒ Button for
driver assist systems .
OR: in the Driver assistance menu in the Infotainment system ⇒ Vehicle settings menu .
If the indicator lamp lights up yellow in the instrument cluster display, the lane keeping system
is switched on but is not active.
The lane keeping system is active at speeds above approximately 65 km/h (40 mph) when lane
markings can be identified ⇒ System limits . The indicator lamp lights up green.

Temporarily switching off the lane keeping system
Switch off the lane keeping system in the following situations:
Very sporty driving.
In poor weather conditions and when driving on poor roads.
In roadworks and before crests in the road.
Driver intervention prompt
In the absence of any steering input, the system prompts the driver with acoustic warnings and a
display on the instrument cluster display to take over active steering.
If the driver does not respond, the system will give another warning by initiating a quick jolt of the
brake before switching to passive mode or activating Emergency Assist (with some equipment
levels).
Steering wheel vibration
The following situations can lead to vibration of the steering wheel:
If the corrective steering intervention is not sufficient to keep the vehicle in its lane.
If the system can no longer detect a lane during a significant steering intervention.

If there is a system fault, the lane keeping system can deactivate itself automatically.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction 
No camera visibility, error message, system switches itself off
Clean the windscreen ⇒ Caring for and cleaning the vehicle exterior .
Check whether any damage is visible on the windscreen in the camera's field of view.
The system is not responding as expected
Regularly clean the camera's field of view, and keep it free from snow and ice.
Do not cover the camera's field of view.
Check the area of the windscreen that is in the camera's field of view for damage.
Do not fit any objects to the steering wheel.
Traffic Jam Assist
Traffic Jam Assist helps the driver to keep in lane, and also provides assistance when following other
vehicles in congestion or slow-moving traffic.
