Steering assistanceThe color of the steering wheel symbol indicates thecurrent status of steeringassistance: • GREEN indicates that steering assistance is active
• GRAY (as shown in illustration) indicates thatsteering assistance is deactivated.
Pilot Assist's steering assistance is based on monitoring the direction of the vehicle aheadand the traffic lane's side marker lines. Thedriver can override Pilot Assist's steering rec-ommendations at any time and steer inanother direction, e.g. to change lanes or avoidobstacles on the road. If the camera/radar sensor cannot detect the lane's side marker lines or if Pilot Assist isunable for some other reason to clearly inter-pret the lane, Pilot Assist will temporarilydeactivate steering assistance until it can onceagain interpret the lane markings. However,the speed and distance warnings will remainactive. The driver will be alerted by slightvibrations in the steering wheel that the func-tion has been temporarily deactivated.
WARNING
Pilot Assist is deactivated automatically and resumes working without prior notice.
In curves and forks in the roadPilot Assist is designed to interact with the driver. The driver should never wait for steer-ing assistance from Pilot Assist, but insteadshould always be ready to increase his or herown steering efforts, particularly in curves. When the vehicle is approaching an off-ramp or a fork in the road, the driver should steertoward the desired lane so that Pilot Assistcan detect the desired direction of travel.
Hands on the steering wheelPilot Assist only functions if the driver's handsare on the steering wheel. It is also importantfor the driver to always continue to be activeand alert when driving since Pilot Assist isunable to read all situations and may togglebetween off and on without prior warning.
If Pilot Assist detects that thedriver's hands are not on thesteering wheel, the systemwill provide a symbol and atext message in the instru-ment panel to instruct thedriver to actively steer the
vehicle.
If the driver's hands are still detected on the steering wheel after a few seconds havepassed, the instructions to actively steer thevehicle will be repeated, accompanied by anaudible signal. If Pilot Assist still does not detect the driver'shands on the steering wheel after a few moreseconds have passed, the audible signal willbecome intense and the steering function willswitch off. Pilot Assist must then be reactiva- ted by pressing the
button on the steering
wheel.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.

WARNING
The driver should be aware that if condi- tions suddenly change when using PassingAssistance, the function may implement anundesired acceleration in certain condi-tions. Some situations should be avoided, e.g. if: the vehicle is approaching an exit in the same direction as passing would nor-mally occur
the vehicle ahead slows before yourvehicle has had time to switch to thepassing lane
traffic in the passing lane slows down
Situations of this type can be avoided by temporarily putting Adaptive Cruise Controlor Pilot Assist in standby mode.

Collision risk warning from driver support
The driver support systems Adaptive Cruise Control * and Pilot Assist * can help alert the
driver if the distance to the vehicle ahead suddenly decreases to an unsafe distance.
Collision warning audible signal and symbol
Audible signal at risk of collision
Collision warning symbol
Camera/radar sensor distance monitoring
Adaptive Cruise Control and Pilot Assist use approx. 40% of the braking capacity. If a sit-uation requires more braking force than driversupport can provide, and if the driver does not apply the brakes, a warning light and audible warning signal will be activated to alert thedriver that immediate action is required.
WARNING
The driver support system only issues a warning for vehicles detected by its radarunit – thus, a warning may come after adelay or not at all. Never wait for a warning.Apply the brakes when necessary.
Collision warning symbol on the windshield
In vehicles equipped with a head-up display *,
a flashing warning symbol will be displayed on the windshield.
NOTE
Visual warnings on the windshield may be difficult to notice in cases of strong sun-light, reflections, extreme light contrasts,or if the driver is wearing sunglasses or isnot looking straight ahead.

The vehicle willreturn to the set speed when the acceleratorpedal is released.
Possible speed
Automatic transmission
The driver support functions can follow another vehicle at speeds from a standstill upto 200 km/h (125 mph). Pilot Assist can provide steering assistance from near-stationary speeds up to 140 km/h(87 mph). The lowest speed that can be set is 30 km/h (20 mph). When following another vehicle,ACC can monitor that vehicle's speed andslow your own vehicle down to a standstill,but it is not possible to set speeds lower than30 km/h (20 mph).

can alert the driver with light,
sound and pulsations in the brake pedal to help the driver detect pedestrians, cyclists,large animals and vehicles.
Function overview
Audible signal at risk of collision
Collision warning symbol
Camera/radar sensor distance monitoring
The function can help the driver avoid a colli- sion in e.g. stop-and-go traffic, when changesin the traffic ahead and driver distraction couldlead to an incident. City Safety activates abrief, forceful braking in an attempt to stopyour vehicle immediately behind the vehicle orobject ahead. The function assists the driver by automati-cally applying the brakes if there is an immi-nent risk of a collision and the driver does notreact in time by braking and/or steering away. City Safety is activated in situations in which the driver should have applied the brakesmuch earlier, which means that the systemwill not be able to assist the driver in all situa-tions. The function is designed to be activatedas late as possible to help avoid unnecessaryintervention. Automatic braking will only beapplied after or during a collision warning. Normally, the occupants of the vehicle will not be aware of City Safety except when the sys-tem intervenes when a collision is imminent.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment.

Rear Collision Warning *85
The Rear Collision Warning 86
(RCW) function
can help the driver avoid rear-end collisions from vehicles approaching from behind.
The function can alert drivers of following vehi- cles of the risk of a collision by rapidly flashingthe turn signals. If, at a speed below 30 km/h (20 mph), the function detects that the vehicle is in dangerof being hit from behind, the seat belt tension-ers may tension the front seat belts. TheWhiplash Protection System will also be acti-vated in a collision. Immediately before a collision from behind, the function may also activate the brakes inorder to reduce the forward acceleration of thevehicle during the collision. However, thebrakes will only be applied if your vehicle isstationary. The brakes will be immediatelyreleased if the accelerator pedal is depressed. The function is automatically activated each time the engine is started.

Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be reduced in certain situations.
In certain situations, the system may provide a warning even if it has not detected a change indriving behavior, e.g.: in strong crosswinds
on grooved road surfaces.
WARNING
In certain cases, driving behavior might not be affected despite the driver's fatigue – when using the Pilot Assist
* function –
resulting in the driver not getting a warning from DAC. It is therefore very important to always stop and take a break at the slightest signof fatigue, regardless of whether the func-tion has issued a warning or not.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.
