Collision warning
Warning light in the windshield
Adaptive Cruise Control can exert brake force that is equivalent to approximately 40% of thevehicle's total braking capacity. In situations requiring more brake force than ACC can provide and if the driver does not applythe brakes, an audible signal from the City Safetysystem will sound and warning light will illuminatein the windshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

Setting an Adaptive Cruise Control time interval
ACC makes it possible to set various time inter- vals to the vehicle ahead.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The greater the number ofbars, the longer the time inter-val. One bar between the vehi-
cles represents a time interval of approximately1 second; 5 bars is approximately 3 seconds. The same symbol appears if Distance Alert is activated.
• If the symbol shows two vehicle's, ACC is actively following the vehicle ahead (a targetvehicle).
• If only one vehicle is displayed, ACC is
not
actively following another vehicle.

Controls for setting a time interval
Reduce the time interval
Increase the time interval
Distance/time indicator
–Press buttons (1) or (2) to reduce or increase the time interval.
> The distance/time indicator (3) shows the current time interval.
In order to follow the vehicle ahead as smoothly as possible, ACC allows the time interval to varyconsiderably in certain situations. At low speeds,when the distance to the vehicle ahead is short,ACC increases the time interval slightly. • If ACC does not seem to react when it is put in active mode, this may be because the set time interval to the vehicle ahead does notallow an increase in speed.
• The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.
• Only use time intervals permitted by localtraffic regulations.
WARNING
•
Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

WARNING
At speeds above 20 mph (30 km/h), if ACC
changes targets from a moving vehicle to a stationary one, the system will not react to the
stationary vehicle and will accelerate to the previously set speed. The driver must actively apply the brakes to slow/stop the vehicle.
Automatic standby mode when changing targets
ACC disengages and goes into standby mode if:
• your vehicle's speed goes below approx. 3 mph (5 km/h) and ACC cannot determineif the target object is a stationary vehicle orsome other type of object such as a speedbump, etc
• the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that ACC nolonger has a target vehicle to follow.
Auto-hold brake functionIn slow-moving, stop-and-go traffic or when stop-ped at a traffic light, driving will resume automati-cally if the vehicle is not stopped for more thanapprox. 3 seconds. If it takes more than3 seconds for the vehicle ahead to begin movingagain, ACC will go into standby mode and theauto-hold brake function will activate.
–The driver will then have to reactivate ACC in one of the following ways:
• Press the
button on the left-side
steering wheel keypad.
• Press the accelerator pedal.
> ACC will resume following the vehicle ahead (target vehicle) if it begins to move within approx. 6 seconds.
NOTE
ACC can keep the vehicle at a standstill for up to 5 minutes, after which the parking brakewill be set and ACC will go into standbymode. The parking brake has to be released before ACC can be reactivated.
Deactivation of the auto-hold brake function
In certain situations, auto-hold will be deactivated when the vehicle is at a standstill and ACC will gointo standby mode. This means that the brakes will be released and the vehicle can begin to roll. The driver must actively apply the brakes to keep the vehicle at a standstill. This can occur in the following situations: • the driver presses the brake pedal
• the parking brake is set •
the gear selector is moved to the
P, N or R
positions
• the driver puts ACC in standby mode.
Automatically setting the parking brakeIn certain situations, the parking brake is set automatically to help keep the vehicle at a stand-still. This occurs if ACC keeps the vehicle at a stand- still with the brakes and:
• the driver unbuckles the seat belt or opensthe door
• ACC has kept the vehicle at a standstill formore than approx. 5 minutes
• the brakes overheat
• the engine is turned off.

• bad weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations: • High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
• Pilot Assist does not "see" pedestrians,animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
Hands on the steering wheel
Pilot Assist only functions when the driver's hands are on the steering wheel
, which is con-
tinuously monitored by the system. If this is notthe case, the driver will be alerted by a text mes-sage in the instrument panel. If the driver's handsare not returned to the steering wheel, an audiblesignal will sound. If the driver does not return his/her hands to thesteering wheel after the audible signal, PilotAssist will go into standby mode and must be reactivated by pressing
.

In order to follow the vehicle ahead as smoothly as possible, Pilot Assist allows the time interval tovary considerably in certain situations. At lowspeeds, when the distance to the vehicle aheadis short, Pilot Assist increases the time intervalslightly.
• If Pilot Assist does not seem to react when itis put in active mode, this may be becausethe set time interval to the vehicle aheaddoes not allow an increase in speed.
• The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.
WARNING
• Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

Changing target vehicles and automatic braking with Pilot Assist
At certain speeds, Pilot Assist can change target vehicles and automatically apply the brakes.
Changing target vehicles
If the target vehicle turns suddenly, there may be a sta- tionary vehicle ahead
When Pilot Assist is actively following another vehicle at speeds under 20 mph (30 km/h) and
changes targets from a moving vehicle to a sta- tionary one, the system will brake for the station-ary vehicle.
WARNING
If Pilot Assist changes targets from a moving vehicle to a stationary one at speeds above
20 mph (30 km/h), the system will not react
to the stationary vehicle and will accelerate to the previously set speed. The driver must actively apply the brakes to slow/stop the vehicle.
Automatic standby mode when changing targets
Pilot Assist disengages and goes into standby mode if:
• your vehicle's speed goes below approx.3 mph (5 km/h) and Pilot Assist cannotdetermine if the target object is a stationaryvehicle or some other type of object such asa speed bump, etc
• the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that Pilot Assistno longer has a target vehicle to follow
Auto-hold brake functionIn slow-moving, stop-and-go traffic or when stop-ped at a traffic light, driving will resume automati-cally if the vehicle is not stopped for more thanapprox. 3 seconds. If it takes more than3 seconds for the vehicle ahead to begin movingagain, Pilot Assist will go into standby mode andthe auto-hold brake function will activate.

WARNING
Pilot Assist is not a collision avoidance sys- tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle. Do not use Pilot Assist in demanding driving conditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps. In certain situations, it may be difficult for Pilot Assist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
• the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad weather conditions (rain, snow, fog, slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations: • High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
• Pilot Assist does not "see" pedestrians,animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
The driver can always take action to override PilotAssist.
Steep roads and/or heavy loadsPilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills. Thedriver should be attentive and prepared to applythe brakes in these situations. Do not use Pilot Assist when the vehicle is trans-porting a heavy load or if it is towing a trailer.
Additional information
•
The Off Road drive mode cannot be
selected if Pilot Assist is activated.
• Pilot Assist uses the vehicle's camera and radar sensor, which have certain general limi-tations. See the articles "Camera limitations"and "Radar sensor limitations" for additionalinformation.
