Pilot Assist
Pilot Assist helps the driver keep the vehicle in the current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.
How Pilot Assist worksThe Pilot Assist function is primarily intended for use on highways and other major roads where itcan help provide a more comfortable and relaxingdriving experience.
The camera/radar sensor monitors the distance to the vehicle ahead and detects lane markings 62
.
Camera and radar sensor
Distance monitor
Lane marker line monitors The driver sets the desired speed and distance to the vehicle ahead. Pilot Assist monitors the dis-tance to the vehicle ahead and the traffic lane'sside markers using the camera and radar sensor.The system maintains the set time interval to thevehicle ahead by automatically adjusting yourvehicle's speed and keeps your vehicle in its laneby providing steering assistance. Pilot Assist's steering assistance is based on monitoring the direction of the vehicle ahead andthe traffic lane's side marker lines. The driver canoverride Pilot Assist's steering recommendationsat any time and steer in another direction, e.g. tochange lanes or avoid obstacles on the road. If the camera/radar sensor cannot detect the lane's side marker lines or if Pilot Assist is unablefor some other reason to clearly interpret thelane, Pilot Assist will temporarily deactivate steer-ing assistance until it can once again interpretthe lane markings. However, the speed and dis-tance warnings will remain active.
WARNING
Pilot Assist is deactivated automatically and resumes working without prior notice.
The color of the steering wheel symbol indicates the currentstatus of steering assistance: • GREEN indicates that steer- ing assistance is active • GRAY (as shown in illustra-
tion) indicates that steering assistance is deacti- vated.
62 Note: This illustration is general and details may vary depending on model.

When the vehicle is approaching an off-ramp or a fork in the road, the driver should steer towardthe desired lane to indicate to Pilot Assist thedesired 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 vehicle appro- priately in the lane, the driver should turn off PilotAssist or switch to Adaptive Cruise Control.

> Pilot Assist will start.
Pilot Assist's steering assis- tance is only active when thesteering wheel symbol (2)changes from GRAY toGREEN. Pilot Assist will only regulate
the time interval to the vehicle ahead when the distance symbol shows a vehicle (1) over thesteering wheel symbol.
A speed interval will be marked at the same time. The higher speed is the set speed for your vehicle and thelower speed is the speed of thevehicle ahead (target vehicle).
Hands on the steering wheelPilot Assist only functions if the driver's hands are on the steering wheel. If Pilot Assist detectsthat the driver's hands are not on the steeringwheel, the driver will be instructed to activelysteer the vehicle by a text message and an audi-ble signal. If Pilot Assist still cannot detect the driver's hands on the steering wheel, the function will gointo standby mode. Pilot Assist must then be reactivated by pressing the
button on the
steering wheel.
NOTE
Note that the Pilot Assist function only works when the driver's hands are on the steeringwheel.

the set speed indicator (3) has moved tothe desired speed.
• The most recently set speed will be stored.
If speed is increased by depressing the accelera- tor pedal while pressing the
button on the
steering wheel, the vehicle's speed when the but- ton is pressed will be stored as the set speed. Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic transmission
Pilot Assist can follow another vehicle at speeds from a standstill up to 200 km/h (125 mph). The lowest speed that can be set for Pilot Assist is 30 km/h (20 mph). When following anothervehicle, ACC can monitor that vehicle's speedand slow your own vehicle down to a standstill,but it is not possible to set speeds lower than30 km/h (20 mph). The highest possible speed that can be set is200 km/h (125 mph).

Setting a time interval for PilotAssist
Pilot Assist can be set to different time intervals.
Different time intervals to the vehicle 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 of
approx. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
NOTE
When the symbol in the instrument panel shows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval. When only a steering wheel is shown, there is no vehicle ahead within a reasonable dis-tance.

WARNING
• With Pilot Assist in standby mode, the driver must intervene and steer and regu-late both speed and distance to the vehi-cle ahead.
• If the vehicle comes too close to a vehicleahead when Pilot Assist is in standbymode, the driver is instead warned of theshort distance by the Distance Alert func-tion.
Standby mode due to action by the driver
Pilot Assist will be temporarily deactivated and put in standby mode if:
• the brakes are applied.
• the gear selector is moved to
N
• a turn signal is used for more than 1 minute.
• the vehicle is driven faster than the setspeed for more than 1 minute
Temporarily increasing speed using the accelera-tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return to the set speed when the accelerator pedal isreleased. When the turn signals are used, Pilot Assist's steering assistance will be temporarily deacti-vated. When the turn signal is switched off, steer-ing assistance will be automatically reactivated ifthe traffic lane's side markings can still bedetected.

Automatic standby mode
Pilot Assist is dependent on other systems, such as Electronic Stability Control (ESC66
). If any of
these other systems stops working, Pilot Assist will automatically switch off.
WARNING
With automatic standby mode, the driver is warned by an acoustic signal and a messageon the instrument panel. • The driver must then regulate vehicle speed, apply the brakes if necessary, andmaintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standbymode if, e.g.: • the driver opens the door.
• the brake temperature is high.
• the driver's hands are not on the steering wheel.
• the parking brake is applied.
• the engine speed (rpm) is too low/high.
• the driver unbuckles the seat belt.
• one or more of the wheels lose traction.
• the camera/radar sensor is covered by snowor heavy rain (the camera lens/radar wavesare blocked) •
your vehicle's speed goes below 5 km/h(3 mph) and Pilot Assist cannot determine ifthe vehicle ahead 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 thatPilot Assist no longer has a vehicle to follow.Reactivating Pilot Assist from standby
mode
Note: This illustration is general and details may vary depending on model.
To reactivate Pilot Assist:
–Press the button on the steering wheel
(1).
> Speed will be set to the most recently stored speed.
WARNING
A noticeable increase in speed may follow when the speed is resumed with the
steering wheel button.

Switching target vehicles with PilotAssist
At certain speeds, models with automatic trans-
missions and Pilot Assist can switch target vehi-cles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When Pilot Assist is actively following another vehicle at speeds under 30 km/h (20 mph) and
switches targets from a moving vehicle to a sta-
tionary vehicle, Pilot Assist will brake for the sta-tionary vehicle.
WARNING
When Pilot Assist follows another vehicle at speeds over approx. 30 km/h (20 mph) and
changes target vehicle – from a moving vehi- cle to a stationary one – Pilot Assist will ignore the stationary vehicle and instead
accelerate to the stored speed.
• The driver must then intervene and apply the brakes.
Automatic standby mode when switching
targets
Pilot Assist disengages and goes into standby mode if:
• your vehicle's speed goes below 5 km/h(3 mph) and Pilot Assist cannot determine ifthe target object is a stationary vehicle oranother object, e.g. a speed bump.
• your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatPilot Assist no longer has a vehicle to follow.

Automatic braking with Pilot Assist
Pilot Assist has a special braking function in slow traffic and at a standstill.
Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stop- ped at a traffic light, driving will resume automati-cally if the vehicle is stopped for less thanapprox. 3 seconds. If it takes more than 3 sec-onds for the vehicle ahead to begin moving again,Pilot Assist will go into standby mode and theAuto-hold brake function will activate.
–Pilot Assist can be reactivated by:
• Pressing the
button on the steering
wheel keypad.
• Pressing the accelerator pedal.
> Pilot Assist will resume following the vehi- cle ahead if it begins to move within approx. 6 seconds.
NOTE
Pilot Assist can keep the vehicle stationary for no more than 5 minutes – after that timethe parking brake is applied and the functionis deactivated. The parking brake must be released before Pilot Assist can be reactivated.

The driver is responsible for ensuring that the vehicle maintains a suitable distancefrom such obstacles.
• The camera and radar sensors do nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects that completely or partiallyblock the route.
• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is lim-ited in force, which means that it cannotalways help the driver to steer and keepthe vehicle within the lane.
• Pilot Assist is switched off if the powersteering is working with reduced power -e.g. during cooling due to overheating(see section "Speed-dependent steeringforce").
The driver can always correct or adjust steeringassistance provided by Pilot Assist by turning thesteering wheel to the desired position.
Steep roads and/or heavy loadsPilot Assist is primarily intended to be driven onflat roads. The function may not be able to main-tain the correct time interval to the vehicle aheadwhen driving down steep hills. The driver should be extra attentive and prepared to apply thebrakes.
• Do not use Pilot Assist if the vehicle is carry-ing a heavy load or towing a trailer.
NOTE
Pilot Assist cannot be activated if a trailer, bike carrier or similar is connected to thevehicle electrical system.
Other limitations
•
The Off Road drive mode cannot be
selected when Pilot Assist is activated.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".
