The system automatically adapts the low-beamheadlamp range depending on the distance tothe other vehicle. Once the system no longerdetects any other vehicles, it reactivates thehigh-beam headlamps.
The system's optical sensor is located behindthe windshield near the overhead control panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize
road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be deac-
tivated or will be activated regardless. There is
a risk of an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take intoaccount road, weather or traffic conditions.Adaptive Highbeam Assist is only an aid. You areresponsible for adjusting the vehicle's lightingto the prevailing light, visibility and traffic con-ditions.
In particular, the detection of obstacles can beimpaired if:
Rthere is poor visibility, e.g. due to fog, heavyrain or snow
Rthere is dirt on the sensors or anything elsecovering the sensors

braking maneuvers. Do not use cruise control orActive Distance Assist DISTRONIC.
If the vehicle threatens to skid or cannot bestopped when moving at low speed:
XShift the transmission to position\\.
The outside temperature indicator is notdesigned to serve as an ice-warning device andis therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.
Indicated temperatures just above the freezingpoint do not guarantee that the road surface isfree of ice. The road may still be icy, especially inwooded areas or on bridges. The vehicle couldskid if you fail to adapt your driving style. Alwaysadapt your driving style and drive at a speed tosuit the prevailing weather conditions.
You should pay special attention to road condi-tions when temperatures are around freezingpoint.

Further information on driving safety systems(Ypage 65).
Cruise control
General notes
Cruise control maintains a constant road speedfor you. It brakes automatically in order to avoidexceeding the set speed. Change into a lower
gear in good time on long and steep downhillgradients. This is especially important if thevehicle is laden or towing a trailer. By doing so,you will make use of the braking effect of theengine. This relieves the load on the brake sys-tem and prevents the brakes from overheatingand wearing too quickly.
Use cruise control only if road and traffic con-ditions make it appropriate to maintain a steadyspeed for a prolonged period. You can store anyroad speed above 20 mph (30 km/h).
Important safety notes
Cruise control can neither reduce the risk of anaccident if you fail to adapt your driving style noroverride the laws of physics. Cruise control can-not take into account the road, traffic andweather conditions. Cruise control is only anaid. You are responsible for maintaining a safedistance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inlane.
Do not use cruise control:
Rin road and traffic conditions which do notallow you to maintain a constant speed, e.g. inheavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-erating could cause the drive wheels to losetraction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,heavy rain or snow
If there is a change of drivers, advise the newdriver of the speed stored.
iThe speed indicated in the speedometermay differ slightly from the speed stored.
Cruise control lever
CActivates or increases speed
DActivates or reduces speed

Driving and pa rking

ple, the detected vehicle turns a corner andan obstacle or stationary vehicle is revealed,Active Distance Assist DISTRONIC will notbrake for them.
RCrossing vehicles: Active Distance AssistDISTRONIC may mistakenly detect vehiclesthat are crossing your lane. Activating ActiveDistance Assist DISTRONIC at, for example, atraffic light with crossing traffic could causeyour vehicle to pull away at the wrong time.
In such situations, brake if necessary. ActiveDistance Assist DISTRONIC will then be deacti-vated.
Active Distance Assist DISTRONIC with
Active Steering Assist
General notes
Active Distance Assist DISTRONIC with ActiveSteering Assist aids you in keeping the vehicle inthe center of the driving lane by means of mod-erate steering interventions in a speed rangefrom 0 - 125 mph (0 - 200 km/h).
It monitors the area in front of your vehicle bymeans of multifunction cameraC, which ismounted at the top of the windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),Active Steering Assist focuses on the vehicle infront, taking into account lane markings, e.g.when following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h),Active Steering Assist focuses on clear lanemarkings (left and right), focusing on the vehiclein front only if clear lane markings are not pres-ent.
If these conditions are not present, Active Steer-ing Assist cannot provide assistance.
Active Distance Assist DISTRONIC must beactive in order for the function to be available.
Important safety notes
Active Distance Assist DISTRONIC with ActiveSteering Assist can neither reduce the risk of anaccident if you fail to adapt your driving style noroverride the laws of physics. Active DistanceAssist DISTRONIC with Active Steering Assistcannot take into account road, weather or trafficconditions. Active Distance Assist DISTRONICwith Active Steering Assist is only an aid. You areresponsible for maintaining a safe distance tothe vehicle in front, for vehicle speed, for brak-ing in good time and for staying in lane.
Active Distance Assist DISTRONIC with ActiveSteering Assist does not detect road and trafficconditions and does not detect all road users. Ifyou are following a vehicle which is drivingtowards the edge of the road, your vehicle couldcome into contact with the curb or other roadboundaries. Be particularly aware of other roadusers, e.g. cyclists, that are directly next to yourvehicle.
Obstacles such as traffic pylons at roadworks onthe lane or projecting out into the lane are notdetected.
An inappropriate steering intervention, e.g. afterintentionally driving over a lane marking, can becorrected at any time if you steer slightly in theopposite direction.
Active Distance Assist DISTRONIC with ActiveSteering Assist cannot continuously keep yourvehicle in lane. In some cases, steering inter-vention is not sufficient to bring the vehicle backto the lane. In such cases, you must steer thevehicle yourself to ensure that it does not leavethe lane.
The system may be impaired or may not functionif:
Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or heavy spray
Rthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)
Rthe windshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the camera
Rthere are no or several unclear lane markingsfor one lane, e.g. roadworks
Rthe lane markings are worn away, dark or cov-ered up, e.g. by dirt or snow
