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.

Introduction
This chapter contains information on the followingsubjects:
⇒ Driving with the lane keeping system
⇒ Troubleshooting
The lane keeping system (Lane Assistyf
helps the driver stay in lane.
Using a camera in the windscreen ⇒ Vehicle overviews, the lane keeping 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 equipmentyf
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 ⇒ Operation and display in the Infotainment system.
System limits
Use the lane keeping system only on motorways and good main roads.
The system is not active under the following conditions:

•Changes have been made to the paintwork in the area of the radar sensors or structural
modifications have been made, e.g. on the vehicle front end or the running gear.
•Tinting foils have been retrofitted on the side windows.
The intelligent technology of the lane change system including Rear Traffic Alert cannot
overcome the laws of physics, and functions only within the limits of the system. Do not
let the auxiliary function of the Rear Traffic Alert tempt you to take any risks while driving
– this can cause accidents. The system is not a substitute for the full concentration of the
driver.
•Never use the system with impaired vision or in unpredictable traffic situations, e.g. on
extremely busy roads or across several lanes.
•Always pay attention to the area around the vehicle – cyclists and pedestrians are
often not clearly detected.
•The Rear Traffic Alert will not always independently bring the vehicle to a complete
stop.
WARNING

Electronic Stability Control (ESCyf
ESC helps to reduce the risk of skidding and to improve driving stability in certain driving situations
⇒.
Depending on the vehicle equipment, ESC can be switched to a Sport mode ⇒ Switching TCS on 
and off.
When ESC is regulating, the yellow indicator lamp is shown on the instrument cluster display.
Traction control system (TCSyf
The TCS reduces the drive output if wheelspin occurs and adapts the output to suit road surface
conditions. The TCS makes it easier to pull away, accelerate and drive up hills.
Depending on the vehicle equipment, the TCS can be switched off in exceptional circumstances
⇒ Switching TCS on and off.
When the TCS is regulating, the yellow indicator lamp is shown on the instrument cluster
display.
Anti-lock brake system
The anti-lock brake system can prevent the wheels from locking when the brakes are applied up
until the point where the vehicle is nearly stationary and assists the driver in steering the vehicle
and keeping it under control.
Brake assist system
The brake assist system can help to reduce the stopping distance. The brake assist system
reinforces brake pressure when the driver depresses the brake pedal quickly in an emergency
situation.
Do not reduce the pressure on the brake pedal when the brake assist system is regulating. If you
reduce the pressure on the brake pedal, the brake assist system will switch off the brake servo.
Electronic differential lock (EDL and XDSyf
EDL brakes the wheel that has lost traction and distributes the driving force to the other drive
wheels.
The EDL switches off automatically under unusually heavy loads to prevent the disc brake from
overheating. The EDL switches back on again automatically as soon as the brake has cooled down.
XDS applies pressure to the brake of the wheel on the inside of the bend. This will improve traction,
helping the vehicle to remain in the required lane longer.
Automatic Post-Collision Braking System
In the event of an accident, the Automatic Post-Collision Braking System can help the driver to
reduce the risk of skidding, and the danger of secondary collisions, through automatic braking.
The Automatic Post-Collision Braking System functions only in front, side and rear collisions when
the airbag control unit detects a corresponding trigger threshold during the accident.
The ESC brakes the vehicle automatically, provided that the hydraulic braking system, the ESC and
the electrical system are undamaged in the accident and remain functional.
The following actions override automatic braking in the event of an accident:
•When the driver depresses the accelerator. No automatic braking occurs.
•When the brake pressure transmitted through the depressed brake pedal is greater than the
brake pressure provided by the system. The vehicle is braked manually.
