Only use the time intervals permitted bylocal traffic regulations.
The set time interval is also used by theAdaptive Cruise Control and Pilot Assistfunctions.

WARNING
Only use a time interval suitable for thecurrent traffic conditions.
The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.

Distance Alert functionality may be reduced incertain situations.
WARNING
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.
A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorter

NOTE
The greater the vehicles' speed, thegreater the distance between them for aset time interval.
Only use the time intervals permitted bylocal traffic regulations.
If the Adaptive Cruise Control does notseem to respond with a speed increasewhen activated, it may be because thetime interval to the vehicle ahead isshorter than the set time interval.

WARNING
Only use a time interval suitable for thecurrent traffic conditions.
The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.

Setting how ACC should maintain
distance * to the vehicle ahead
A number of different settings can be made forhow Adaptive Cruise Control should maintain atime interval to the vehicle ahead. Settings aremade using the DRIVE MODE controls.
Select one of the following:
Eco - ACC will focus on providing optimalfuel economy, which will increase the timeinterval to the vehicle ahead.
Comfort - ACC will focus on following theset time interval to the vehicle ahead assmoothly as possible.
Dynamic - ACC will focus on following theset time interval to the vehicle ahead moreexactly, which could mean faster accelerationand heavier braking.

Setting a time interval for PilotAssist
Pilot Assist can be set to different time intervals.
Different time intervals to thevehicle 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 ofapprox. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.

NOTE
When the symbol in the instrument panelshows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval.
When only a steering wheel is shown, there isno vehicle ahead within a reasonable dis-tance.
Controls for setting a time interval55.
Reduce the time interval
Increase the time interval
Distance indicator
–Press the (1) or (2) button to decrease orincrease the time interval.
> The distance indicator (3) shows the cur-rent time interval.
In order to follow the vehicle ahead as smoothlyas possible, Pilot Assist allows the time interval tovary considerably in certain situations. For exam-ple, at low speeds and short distances to thevehicle ahead, Pilot Assist increases the timeinterval slightly.
NOTE
The greater the vehicles' speed, thegreater the distance between them for aset time interval.
Only use the time intervals permitted bylocal traffic regulations.
If Pilot Assist does not seem to respondwith a speed increase when activated, itmay be because the time interval to thevehicle ahead is shorter than the set timeinterval.

WARNING
Only use a time interval suitable for thecurrent traffic conditions.
The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.

Setting how Pilot Assist should
maintain distance * to the vehicle ahead
The driver can choose different drive modes todetermine how Pilot Assist should maintain atime interval to the vehicle ahead. Settings aremade using the DRIVE MODE controls.
