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.
•Vehicles that change into your lane directly in front of your vehicle ⇒ Fig. 144.

⇒ Pedestrian Monitoring
⇒ System limits
⇒ Troubleshooting
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.
