For vehicles with both CC and ACC
–Change a set speed by pressing the (1)
or (3) buttons briefly or by pressing andholding them:
Press briefly: Press briefly: each presschanges the speed in +/- 5 mph(+/- 5 km/h) increments.
Press and hold: release the button whenthe set speed indicator (4) 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 (1) button onthe steering wheel, the vehicle's speed when thebutton 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.

Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applyingthe brakes. On downgrades, it can sometimes bedesirable to roll a bit faster and let speed bereduced instead by engine braking alone. Thedriver can temporarily disengage the Cruise Con-trol braking function.
To disengage CC:
–Press the accelerator pedal about halfwaydown and then release it.
> Cruise Control will automatically disen-gage the automatic brake function andspeed will only be reduced using theengine braking function.
How drive mode affects cruise control
The way the cruise control maintains the vehicle'sspeed can vary depending on the selected drive
mode22.

Cruise Control Eco Cruise with ECO drive
mode
In the ECO drive mode, cruise control's accelera-tion and deceleration will be smoother than inother drive modes to help provide optimal fuelefficiency and reduced environmental impact.Because of this, the vehicle's actual speed maybe slightly above or below the set speed.

Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control'sacceleration and deceleration will be faster andmore immediate than in other drive modes.

Starting passing assistance withAdaptive Cruise Control
Several conditions must be met for passingassistance to be possible.

Requirements for passing assistance
In order to activate passing assistance:
your vehicle must be following a vehicleahead (target vehicle)
your vehicle's current speed must beat least 70 km/h (43 mph)
the set speed for ACC must be highenough to safely pass another vehicle.

Starting parking assistance
To start passing assistance:
–Turn on the left turn signal.
> Passing assistance will start.

Limitations of passing assistancewith Adaptive Cruise Control
Passing assistance functionality may be reducedin certain situations.
WARNING
The driver should be aware that if conditionssuddenly change when using Parking Assis-tance, the function may implement an unde-sired acceleration in certain conditions.
Some situations should be avoided, e.g. if:
the vehicle is approaching an exit in thesame direction as passing would normallyoccur
the vehicle ahead slows before your vehi-cle has had time to switch to the passinglane
traffic in the passing lane slows down
a vehicle for right-hand traffic is driven ina country with left-hand traffic (or viceversa).
Situations of this type can be avoided by tempo-
rarily putting ACC45 in standby mode.

Switching target vehicles withAdaptive Cruise Control
At certain speeds, models with automatic trans-
missions and Adaptive Cruise Control (ACC46)can switch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may bestationary 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 movingvehicle to a stationary vehicle, Adaptive CruiseControl will brake for the stationary vehicle.

* Option/accessory.303

WARNING
When Adaptive Cruise Control follows anothervehicle at speeds over approx. 30 km/h(20 mph) and changes target vehicle – from amoving vehicle to a stationary one – AdaptiveCruise Control will ignore the stationary vehi-cle and instead accelerate to the storedspeed.
The driver must then intervene and applythe brakes.

Automatic standby mode when switching
targets
Adaptive Cruise Control will be disabled and gointo 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 (ACC47) 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 inone of the following ways:
Pressing the button on the steeringwheel keypad.
Pressing the accelerator pedal.
> Adaptive Cruise Control will resume fol-lowing the vehicle ahead if it begins tomove within approx. 6 seconds.
NOTE
ACC can keep the vehicle stationary for nomore than 5 minutes – after that time theparking brake is applied and Adaptive CruiseControl is deactivated.
The parking brake must be released beforeAdaptive Cruise Control can be reactivated.

Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivatedwhen 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 Rpositions
the driver puts Adaptive Cruise Control instandby mode.

Auto Activate Parking Brake
In certain situations, the parking brake will beapplied to keep the vehicle at a standstill.

Pilot Assist
Pilot Assist helps the driver keep the vehicle inthe current traffic lane by providing steeringassistance and maintaining an even speed and aset time interval to the vehicle ahead.

How Pilot Assist works
The Pilot Assist function is primarily intended foruse on highways and other major roads where itcan help provide a more comfortable and relaxingdriving experience.
The camera/radar sensor monitors the distance to thevehicle ahead and detects lane markings52.
Camera and radar sensor
Distance monitor
Lane marker line monitors
The driver sets the desired speed and distance tothe 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 onmonitoring 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 thelane'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 andresumes working without prior notice.
The color of the steering wheelsymbol 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.
