The Distance Alert function can help the driverbecome aware if the time interval to the vehiclein front is too short. The vehicle must be equip-ped with a head-up display* in order to displayDistance Alert.
Symbol for Distance Alert on the windshield with head-up display
In vehicles equipped with a head-up display, asymbol will be displayed on the windshield aslong as the time interval to the vehicle ahead isshorter than the set time interval. However, theShow Driver Support function must be acti-vated under Settings in the vehicle's menu sys-tem.
Distance Alert is active at speeds above 30 km/h(20 mph) and only reacts for vehicles ahead mov-ing in the same direction as your vehicle. No dis-tance information is provided for oncoming, slow-moving or stationary vehicles.
NOTE
Visual warnings on the windshield may be dif-ficult to notice in cases of strong sunlight,reflections, extreme light contrasts, or if thedriver is wearing sunglasses or is not lookingstraight ahead.
NOTE
Distance Alert is deactivated while Adaptive
Cruise Control (ACC17) or Pilot Assist isactive.
WARNING
Distance Alert only reacts of the time intervalto the vehicle ahead is shorter than the presetvalue – vehicle speed is not affected.

WARNING
The function is supplementary driver sup-port intended to facilitate driving and helpmake it safer – it cannot handle all situa-tions in all traffic, weather and road condi-tions.
The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion.
Driver support functions are not a substi-tute for the driver's attention and judg-ment. The driver is always responsible forensuring the vehicle is driven in a safemanner, at the appropriate speed, with anappropriate distance to other vehicles,and in accordance with current trafficrules and regulations.
NOTE
The function uses the vehicle's camera andradar sensor, which has certain general limita-tions.

Adaptive Cruise Control*20
Adaptive Cruise Control (ACC21) helps thedriver maintain a constant speed with a set timeinterval to the vehicle ahead.
Adaptive Cruise Control can help provide a morerelaxed driving experience on long trips on high-ways or long, straight roads with even trafficflows.
The camera/radar sensor measures the distance to thevehicle ahead.
The driver sets a speed and a time interval to thevehicle ahead. If the camera/radar sensor detectsa slower-moving vehicle ahead, your vehicle'sspeed will be automatically adapted according tothe set time interval to that vehicle. When thereare no longer slower-moving vehicles ahead, thevehicle will return to the set speed.

The driver is always responsible forensuring the vehicle is driven in a safemanner, at the appropriate speed, with anappropriate distance to other vehicles,and in accordance with current trafficrules and regulations.
Pilot Assist regulates speed by accelerating andbraking. It is normal for the brakes to emit a slightsound when they are being used to adjust speed.
Pilot Assist attempts to smoothly regulate speed.The driver must apply the brakes in situationsrequiring immediate braking. For example, whenthere are great differences in speed betweenvehicles or if the vehicle ahead brakes suddenly.
Due to limitations in the camera and radar sen-sor, braking may occur unexpectedly or not at all.
Pilot Assist is designed to follow a vehicle aheadin the same lane and maintain a time interval tothat vehicle set by the driver. If the radar sensordoes not detect a vehicle ahead, it will insteadmaintain the speed set by the driver. This will alsohappen if the speed of the vehicle aheadexceeds the set speed for your vehicle.
WARNING
This is not a collision avoidance system.The driver is always responsible and mustintervene if the system fails to detect avehicle ahead.
The function does not brake for people oranimals and does not brake for smallvehicles, such as bikes and motorcycles.Similarly, it does not brake for low trailers,oncoming, slow-moving or stationary vehi-cles and objects.
Do not use the function in demanding sit-uations, such as in city traffic, at intersec-tions, on slippery surfaces, with a lot ofwater or slush on the road, in heavy rain/snow, in poor visibility, on winding roads,or on on/off ramps.
CAUTION
Maintenance of driver support components
may only performed by a workshop31.
In curves and forks in the road
Pilot Assist is designed to interact with the driver.The driver should never wait for steering assis-tance from Pilot Assist, but instead should alwaysbe ready to increase his or her own steeringefforts, particularly in curves.
When the vehicle is approaching an off-rampor a fork in the road, the driver should steertoward the desired lane to indicate to PilotAssist the desired direction of travel.
Pilot Assist strives to keep the vehicle
in the center of the lane
When Pilot Assist provides steering assistance, itstrives to position the vehicle in the center of thelane between the lane markings. For the smooth-est driving experience possible, the driver shouldpermit the vehicle to find the optimal positioning.The driver should check that the vehicle is posi-tioned safely in the lane and can always adjustthe vehicle's position by applying more force tothe steering wheel.
If Pilot Assist does not position the vehicleappropriately in the lane, the driver should

Pilot Assist limitations
Pilot Assist functionality may be reduced in cer-tain situations.
Pilot Assist is a driver support function designedto simplify driving and assist the driver in manysituations. However, the driver is always responsi-ble for maintaining a suitable distance to vehiclesor objects around it and ensuring that the vehicleis correctly positioned in the traffic lane.
WARNING
In some situations, Pilot Assist may have trou-ble helping the driver properly or may bedeactivated automatically – we advise againstusing Pilot Assist in such cases. Examples ofsuch situations include:
the lane markings are worn, missing orcross each other.
lane division is unclear, for example, whenthe lanes divide or merge or at exits orwhen there are multiple sets of markings.
edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edges orstrong shadows.
the lane is narrow or winding.
the lane contains ridges or holes.
weather conditions are poor, e.g. rain,snow or fog or slush or reduced visibilitywith poor light conditions, backlighting,wet road surface, etc.
The driver should also note that Pilot Assisthas the following limitations:
High curbs, roadside barriers, temporaryobstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane mark-ings, with a subsequent risk of contactbetween the vehicle and such obstacles.

The previous illustration34 shows that Pilot Assistis set to maintain a speed of 110 km/h (68 mph)and that there is no target vehicle ahead to fol-low.
Pilot Assist will provide steering assistancebecause it can detect the lane's side markinglines.

Camera/radar sensor distance monitoring
Driver support uses approx. 40% of the vehicle'sbraking capacity. If a situation requires morebraking force than driver support can provide, andif the driver does not apply the brakes, a warning
light and audible warning signal will be activatedto alert the driver that immediate action isrequired.
WARNING
The driver support system only issues a warn-ing for vehicles detected by its radar unit –thus, a warning may come after a delay or notat all. Never wait for a warning. Apply thebrakes when necessary.

Switching target vehicles with driversupport
At certain speeds, vehicles with automatic trans-missions and the driver support functions Adap-
tive Cruise Control*36 and Pilot Assist canswitch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may bestationary traffic ahead.
When driver support is actively following anothervehicle at speeds under 30 km/h (20 mph) andswitches targets from a moving vehicle to a sta-tionary vehicle, driver support will brake for thestationary vehicle.
WARNING
When driver support follows another vehicle atspeeds over approx. 30 km/h (20 mph) andchanges target vehicle – from a moving vehi-cle to a stationary one – driver support willignore the stationary vehicle and insteadaccelerate to the stored speed.
The driver must then intervene and applythe brakes.
Automatic standby mode when switching
targets
Driver support disengages and goes into standbymode if:
your vehicle's speed goes under 5 km/h(3 mph) and driver support cannot determineif the target vehicle is stationary or if it isanother object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatdriver support no longer has a vehicle to fol-low.

Set time interval for driver support
The time interval to the vehicle ahead can be set
for the functions Adaptive Cruise Control*37,Pilot Assist and Distance Alert*.
Different time intervals to thevehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The more bars, the longerthe time interval. One bar rep-resents an interval ofapprox. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
NOTE
When the symbol in the instrument panelshows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval.
When only a steering wheel is shown, there isno vehicle ahead within a reasonable dis-tance.
NOTE
When the symbol in the instrument panelshows two vehicles, ACC is following the vehi-cle ahead at a preset time interval.
When only one vehicle is shown, there is novehicle ahead within a reasonable distance.

–Press the (1) or (2) button to decrease orincrease the time interval.
>The distance indicator (3) shows the cur-rent time interval.
In order to help your vehicle follow the vehicleahead as smoothly and comfortably as possible,Adaptive Cruise Control allows the time intervalto vary noticeably in certain situations. At lowspeeds, when the distance to the vehicle aheadis short, Adaptive Cruise Control increases thetime interval slightly.
NOTE
The greater the vehicles' speed, thegreater the distance between them for aset time interval.
Only use the time intervals permitted bylocal traffic regulations.
If driver support does not seem torespond with a speed increase when acti-vated, it may be because the time intervalto the vehicle ahead is shorter than theset time interval.
WARNING
Only use a time interval suitable for thecurrent traffic conditions.
The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.
