Lane assistance steers the car back into its lane.
Lane assistance warns with steering wheel vibrations23
.
Depending on settings, lane assistance acts in accordance with the following:
1. Steering assistance activated: When the car
is approaching a lane line, LKA will actively steer the car back into its lane by applying a slight torque to the steering wheel.
2. Warning activated: If the car is about to cross a lane line, the driver is warned by means ofan acoustic signal or vibration in the steeringwheel.
NOTE
When a direction indicator is switched on, there are no steering corrections or alertsfrom Lane assistance.
WARNING
Lane assistance is merely a driver aid and does not engage in all driving situations ortraffic, weather or road conditions. The driver always bears ultimate responsibility for ensuring that the vehicle is driven safelyand that applicable laws and road traffic regu-lations are followed.
Steering assistanceA precondition for the functioning of the LKA steering assistance is that the driver

Lane assistance does not intervene
Lane assistance does not engage on sharp inside curves.
In some situations, lane assistance allows lane lines to be crossed without intervening with eithersteering assistance or a warning - e.g. whenusing the direction indicators or cutting bends.
LimitationsIn certain demanding conditions lane assistancemay have difficulty helping the driver correctly. Insuch cases it is recommended to switch off thisfunction. Examples of such conditions are:• road works
• winter road conditions
• poor road surface
• a very “sporty” driving style •
poor weather with reduced visibility
• sharp edges or lines other than the lane lines
• roads with unclear or non-existent line mark- ings.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.

Run-off Mitigation
The function of Run-off Mitigation is to assist the driver to reduce the risk of the car accidentallyleaving the road by means of actively steeringthe car back onto the road.
The function is active within the speed range 65-140 km/h (40-87 mph) on roads with clearlyvisible side markings/lane lines. A camera scans the edges of the road and the painted side markings. If the car is about to crossthe edge of the road, Run-off Mitigation willactively steer the car back onto the road. In addi-tion, if steering intervention is considered insuffi-cient to avoid run-off, brake intervention may alsobe activated. Run-off Mitigation does not intervene with either steering assistance or brake intervention if thedirection indicators are used. If the functiondetects that the driver is driving the car in anactive way, activation of Run-off Mitigation will besuppressed for a short time. The function has two activation levels: • Steering assistance only
• Steering assistance with brake intervention
Run-off Mitigation with steering assistance
Run-off Mitigation intervenes with steering assistance.
Run-off Mitigation with steering assistance
and brake intervention
Run-off Mitigation intervenes with steering assistance and braking.
Brake intervention helps in situations where steering assistance alone is not sufficient. Thebrake force is adapted automatically dependingon the situation at the time of run-off.
Settings for Run-off MitigationThe Run-off Mitigation function is selectable -the driver can select On or Off by dragging downthe centre display's top view and there searchingfor the following:
SettingsMy CarIntelliSafeLane
Assistance
To activate Run-off Mitigation:
• Select the box at
Collision Avoidance
Assistance, Steering aid during
increased collision risk - the function is
then activated.
The current setting for Run-off Mitigation when the engine is switched off remains the next timethe engine is started.
Limitations of Run-off MitigationIn certain demanding conditions, Run-off Mitiga-tion may have difficulty helping the driver cor-rectly. In such cases, it is recommended that thefunction be switched off. Examples of such conditions are:
• road works
• winter road conditions

STARTING AND DRIVING

snaking. The function is included in the stability system ESC19
.
Reasons for snakingThe snaking phenomenon can occur with any car/trailer combination. Snaking normally occursat high speeds. But, there is a risk of it occurringat lower speeds if the trailer is overloaded or theload is improperly distributed, e.g. too far back. In order for snaking to occur, there must be a triggering factor, e.g.: • Car with trailer subjected to a sudden and powerful side wind.
• Car with trailer drives on an uneven road sur-face or in a pothole.
• Sweeping steering wheel movements.
If snaking has started, it could be difficult or evenimpossible to suppress. This makes the car/trailer combination difficult to control and there isa risk that you could, for example, end up in thewrong lane or leave the carriageway.
Trailer Stability Assist functionThe trailer stability assist function continuallymonitors car movements, particularly lateralmovements. If snaking is detected, the frontwheels are individually braked. This serves to sta-bilise the car/trailer combination. This is oftenenough to help the driver regain control of thecar. If snaking is not eliminated the first time thattrailer stability assist comes into action, the car/trailer combination is braked with all wheels andengine power is reduced. Once snaking has beengradually suppressed and the car/trailer combi-nation is stable once again, the system stopsregulating and the driver once again has full con-trol of the car.
NOTE
The stability function is deactivated if the driver selects Sport mode by deactivating
ESC via the menu system in the centre dis-
play.
The trailer stability assist may fail to engage if the driver uses severe steering wheel movements totry to rectify the snaking because in such a situa-tion the system cannot determine whether it isthe trailer or the driver that is causing the snak-ing.
When trailer stability assist is operating, the ESC symbol
flashes in the driver display.
