and an acoustic warning is given. Brake immediately!
Radar sensor
ACC 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.

WARNING
The intelligent technology used in the ACC cannot overcome the laws of physics, and functions only
within the limits of the system. Never let the extra convenience tempt you into taking safety risks
when driving. Careless or unintentional use of the Adaptive Cruise Control (ACC) can cause accidents
and lead to serious injury. 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.
Never use the ACC in poor visibility, on steep or winding roads, or on slippery road surfaces e.g. due
to snow, ice, wet roads, loose chippings, or on flooded roads.
Never use the ACC offroad or on non-surfaced roads. The ACC is designed for use on surfaced roads
only.
The ACC will not react to stationary vehicles.
The ACC will 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.
Special driving situations

Fig. 118 On the instrument cluster display: slower vehicle detected in the left-hand lane (illustration).

If the radar sensor is exposed to environmental conditions that impair sensor functioning, the
system may detect this only after a certain time. For this reason, possible functional restrictions may
be displayed only after a delay at the start of the journey and when driving ⇒ .
Objects that cannot be detected
Persons.
Animals.
Stationary vehicles.
Crossing or oncoming vehicles.
Other stationary obstacles.
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. 120  .
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. 119  .
Vehicles outside the sensor range
Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g. motorbikes
⇒ Fig. 119  .
Vehicles that change into your lane directly in front of your vehicle ⇒ Fig. 120  .
Vehicles with bodies or attachments that project beyond the vehicle.

WARNING
If you use ACC in the above situations, this can result in accidents and serious injuries as well as
violation of legal regulations.

settings of the Infotainment system ⇒ Vehicle settings menu .

WARNING
If you do not maintain the minimum distance to a vehicle in front and the difference in speed
between the vehicle in front and your own vehicle is so great that the braking action of the ACC is
insufficient, you are in danger of colliding with the vehicle in front. The braking distance is also
longer in rain and winter road conditions.
ACC may not be able to detect all driving situations correctly.
Always be prepared to brake the vehicle yourself.
Speed and distance control are overridden when you press the accelerator. ACC does not brake
automatically in this case.
Observe any country-specific regulations relating to the minimum distance.
Always set a larger distance in wet or snowy conditions or when visibility is poor.

Some settings can be stored in the user accounts of the personalisation function and therefore
change automatically when the user account changes ⇒ Personalisation .

Area monitoring system (Front Assist)
Introduction
This chapter contains information on the followingsubjects:
⇒ Warning levels and braking intervention 
⇒ Limits of Front Assist 
⇒ Pedestrian Monitoring 
⇒ Operating the area monitoring system (Front Assist) 
⇒ Troubleshooting 
The area monitoring system (Front Assist) with City Emergency Braking System and Pedestrian
Monitoring 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 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

The system is able to detect possible collisions with vehicles in front or pedestrians crossing in front
of the vehicle and prepares the vehicle for a possible emergency braking procedure.
A warning tone sounds and the red warning lamp lights up. Brake or take avoiding action.
Speed range: around 30 km/h (20 mph) to 250 km/h (155 mph).
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 avoiding action.
Speed range: around 30 km/h (20 mph) to 250 km/h (155 mph).
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 mph) to 250 km/h (155 mph).
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 mph) to 250 km/h (155 mph).
City Emergency Braking System
The City Emergency Braking System is part of Front Assist. If the driver does not react to a possible
collision, the system can also automatically brake the vehicle with increasing braking force without
any advance warning.
The red warning lamp lights up
Speed range: around 5 km/h (3 mph) to 30 km/h (20 mph).
Limits of Front Assist
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Front Assist is not available or its functions are restricted for a period of around 30 seconds (also
longer, depending on the driving situation) immediately after the vehicle is started.
Front Assist has physical and system-related limitations. You should therefore always be prepared to
take full control of the vehicle if necessary.
Delayed response
If the radar sensor is exposed to environmental conditions that impair sensor functioning, the
system may detect this only after a certain time. For this reason, possible functional restrictions may
be displayed only after a delay at the start of the journey and when driving ⇒ .

Poor road conditions.
Driving through road works.
In urban areas.

WARNING
The intelligent technology of Traffic Jam Assist cannot overcome the laws of physics, and functions
only within the limits of the system. Always take care when using Traffic Jam Assist as you could
otherwise 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.
Do not use Traffic Jam Assist in urban traffic.
Do not use Traffic Jam Assist in poor visibility, on steep or winding roads, or on slippery road
surfaces e.g. on snow, ice, wet roads, loose chippings or flooded roads.
Never use Traffic Jam Assist offroad or on unsurfaced roads. Traffic Jam Assist is designed solely for
use on surfaced roads.
Traffic Jam Assist does not react to persons, animals or vehicles crossing or approaching in the same
lane.
If the speed reduction achieved by Traffic Jam Assist is insufficient, brake the vehicle immediately by
depressing the foot brake.
If the vehicle starts to roll unintentionally after the driver has been prompted to take control of the
vehicle, brake the vehicle immediately using the foot brake.
If a driver intervention prompt appears on the instrument cluster display, take control of the vehicle
immediately.
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 driver must be prepared to take control of the vehicle (by accelerating or braking) at all times.

If Traffic Jam Assist does not function as described in this chapter, do not use the system and go to a
qualified workshop.

If there is a fault in the system, visit a qualified workshop and have the system checked.
