Switching target vehicles withAdaptive Cruise Control
At certain speeds, models with automatic trans- missions and Adaptive Cruise Control (ACC 53
)
can switch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When Adaptive Cruise Control is actively follow- ing another vehicle at speeds under 30 km/h
(20 mph) and switches targets from a moving vehicle to a stationary vehicle, Adaptive CruiseControl will brake for the stationary vehicle.
WARNING
When Adaptive Cruise Control follows another vehicle at speeds over approx. 30 km/h
(20 mph) and changes target vehicle – from a moving vehicle to a stationary one – Adaptive Cruise Control will ignore the stationary vehi-
cle and instead accelerate to the stored speed. • The driver must then intervene and apply the brakes.
Automatic standby mode when switching
targets
Adaptive Cruise Control will be disabled and go into standby mode:
• if your vehicle's speed goes below 5 km/h(3 mph) and Adaptive Cruise Control cannotdetermine if the target object is a stationaryvehicle or another object, e.g. a speed bump.
• if your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatAdaptive Cruise Control no longer has a vehi-cle to follow.

Automatic braking with AdaptiveCruise Control The Adaptive cruise control (ACC 54
) has a spe-
cial brake function in slow traffic and while sta- tionary.
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,Adaptive Cruise Control will go into standbymode and the Auto-hold brake function will acti-vate.
–Adaptive Cruise Control can be reactivated in one of the following ways:
• Pressing the
button on the steering
wheel keypad.
• Pressing the accelerator pedal.
> Adaptive Cruise Control will resume fol- lowing the vehicle ahead if it begins to move within approx. 6 seconds.

NOTE
ACC can keep the vehicle stationary for no more than 5 minutes – after that time theparking brake is applied and Adaptive CruiseControl is deactivated. The parking brake must be released before Adaptive Cruise Control 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 AdaptiveCruise Control will go into standby mode. Thismeans that the brakes will be released and thevehicle could begin to roll. The driver mustactively apply the brakes to keep the vehicle sta-tionary. This can occur if:
• the driver depresses the brake pedal
• the parking brake is applied
• the gear selector is moved to the
P
, N
or R
positions
• the driver puts Adaptive Cruise Control in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will beapplied to keep the vehicle at a standstill. This occurs if Adaptive Cruise Control is keepingthe vehicle stationary using the brakes and:
• the driver opens the door or unbuckleshis/her seat belt
• ACC has kept the vehicle at a standstill formore than approx. 5 minutes
• the brakes overheat
• the driver switches off the engine manually.

Adaptive Cruise Control limitations
Adaptive Cruise Control (ACC 55
) may have lim-
ited functionality in certain situations.
Steep roads and/or heavy loadsAdaptive Cruise Control is primarily intended to be driven on flat roads. The function may not beable to maintain the correct time interval to thevehicle ahead when driving down steep hills. Thedriver should be extra attentive and prepared toapply the brakes.
• Do not use Adaptive Cruise Control if thevehicle is carrying a heavy load or towing atrailer.
Other limitations
•
The Off Road drive mode cannot be
selected if Adaptive Cruise Control is acti- vated.
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".

Switching between Cruise Controland Adaptive Cruise Control
In vehicles equipped with Adaptive Cruise Con- trol (ACC 56
), the driver can switch between
Cruise Control (CC 57

Cruise control Adaptive Cruise Control
A WHITE symbol: The function is active. GRAY symbol: Standby mode
Switching from ACC to CCTo do so: 1. Press the
button on the steering wheel
keypad to put Adaptive Cruise Control in standby mode. 2.
Tap the
Cruise Control button in the center
display's Function view. The button's indica- tor will change from GRAY to GREEN.

change from
ACC to CC, indicating that Adaptive Cruise Con- trol is off and Cruise Control is in standbymode.
3. Pressing the
button on the steering
wheel keypad.
> Cruise Control will start and the vehicle's current speed will be set.
WARNING
Switching from ACC to CC means that the vehicle:
• will no longer maintain a preset time interval to the vehicle ahead.
• will only follow the stored speed and thedriver must therefore apply the brakeswhen necessary.
If CC is active when the engine is turned off, ACC
will be automatically activated the next time theengine is started.

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.

310With Adaptive Cruise Control in
standby mode:
1. Press the
▶ button on the steering wheel (6).
> The
symbol will change to Pilot
Assist in standby mode (8).
2. Press the
button on the steering wheel
(2).
> Pilot Assist will start and the current speed will be stored, which will be shown by numbers in the center of the speedom-eter.
...or... With Adaptive Cruise Control started:
–Press the ▶ button on the steering wheel (6).
> 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.
