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.

The radar sensor has a limited field ofvision. In some situations, it may detect avehicle later than expected or not detectother vehicles at all.
The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see. Poorweather or winding roads can affect theradar sensor's capacity to detect vehiclesahead.
