The radar unit is used by the following functions:
• Distance Warning
*
• Adaptive cruise control
*
• Pilot Assist
*
• City Safety
Modification of the radar unit could result in its use being illegal.

CauseAction
Water or snow from the road surface swirls up and blocks the radar signals or camera view. No action. Sometimes the unit does not work on a very wet or snow-coveredroad surface.
Dirt has appeared between the inside of the windscreen and the cameraand radar unit. Visit a workshop to have the windscreen inside the unit's cover cleaned - anauthorised Volvo workshop is recommended.
NOTE
Keep the windscreen clean in front of the camera and radar unit.
Vehicle speedThe capacity of the radar unit to detect vehicles ahead is reduced significantly if:
• the speed of the vehicle ahead is signifi-cantly different from that of your own car
Limited field of visionThe radar unit has a limited field of vision. Insome situations another vehicle is not detected,or the detection is made later than expected.
The radar unit's field of vision.
Sometimes the radar unit is late at detecting vehicles at close distances - e.g. a vehicle that drives in between your car and the vehi-cle ahead.
Small vehicles, such as motorcycles, or vehi- cles not driving in the centre of the lane canremain undetected.
In bends, the radar unit may detect the wrong vehicle or lose a detected vehicle fromview.
Low trailers
Low trailer in radar shadow.
Low trailers can also be difficult for the radar unit to detect, or are not detected at all - the drivershould therefore be particularly careful when driv-ing behind low trailers when the adaptive cruisecontrol or Pilot Assist is activated.

With 8-inch driver display
The symbol is shown in the lower edge of the speedometer.
Symbol Specification
White symbol: The function is avail- able.

Conditions for the Start/Stop function For the Start/Stop function to work requires that a number of conditions are met.
If any condition is not met, this will be indicated in the driver display. See the section "Using theStart/Stop function".
The engine does not auto-stopThe engine does not auto-stop in the followingcases: • The car has not reached approx. 10 km/h (6 mph) after starting.
• After a number of repeated auto stops,speed must again exceed approx. 10 km/h(6 mph) before the next auto stop.
• The driver has unfastened the seatbelt.
• The capacity of the starter battery is belowthe minimum permissible level.
• The engine is not at normal operating tem-perature.
• The ambient temperature is under -5 °C orabove approx. 30 °C.
• the windscreen's electric heating is activated.
• The environment in the passenger compart-ment deviates from the set values.
• the car is reversed.

* Option/accessory.403
In the centre display's function view
A car without drive mode con- trol has a function button for
Driving mode ECO in the
centre display's function view.
–Press the button in order to activate the function.
> An indicator in the button illuminates when the function is activated.
Freewheel function Eco Coast 10The freewheel function Eco Coast means in prac- tice that engine braking ceases, meaning in turnthat the car's kinetic energy is used to freewheelfor longer distances. When the driver releasesthe accelerator pedal the gearbox is automaticallydisengaged from the engine whose speed isreduced to idling speed with reduced consump-tion. The function is best used where it is possible to freewheel a long way, e.g. roads with a slightdownhill gradient or when there is a predictablespeed reduction to freewheel into a zone with alower speed limit.
Activating the freewheel function
The function is activated when the accelerator pedal is fully released, in combination with thefollowing parameters:
• Drive mode
Eco is activated.
• The gear selector is in
D position.
• Speed within the range of approx. 65-140 km/h (40-87 mph).
• The road's downhill gradient is not steeperthan approx. 6%.
The driver display shows
COASTING when the
freewheel function is being used.
Limitations
The freewheel function is not available if:
• Engine and/or gearbox are not at normal operating temperature.
• The cruise control is activated.
• The gear selector is moved from the
D posi-
tion and the manual position.
• The speed is outside the range ofapprox. 65-140 km/h (40-87 mph).
• The road's downhill gradient is steeper thanapprox. 6%.
• Manual gear changing is performed with the steering wheel paddles
*.
Deactivating and switching off the freewheel function
In certain situations it may be desirable to deacti- vate or switch off the function in order to useengine braking. Examples of such situations maybe on steep downhill gradients or before animminent overtaking manoeuvre - in order to beable to do it in the safest way possible. Deactivate the freewheel function as follows:
• Actuate the accelerator or brake pedal.
• Move the gear selector to manual position.
• Changing gear with steering wheel paddles
*.
Switch off the freewheel function as follows:
• Change drive mode
*, or switch off the
Driving mode ECO in the function view.
Even without the freewheel function, it is possible to freewheel for short distances. This, in turn,reduces consumption. However, for the best fueleconomy it is better to have the freewheel func-tion activated and be able to freewheel for longerdistances.
ECO gauge in the driver displayThe ECO gauge indicates how fuel-efficient thedriving is:
