Volvo XC90: Driver support / Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be reduced in certain situations.
In certain situations, the system may provide a warning even if it has not detected
a change in driving behavior, e.g.:
- in strong crosswinds
- on grooved road surfaces.

In certain cases, driving behavior might not be affected despite the driver's
fatigue – when using the Pilot Assist* function – resulting in the driver not getting
a warning from DAC.
It is therefore very important to always stop and take a break at the slightest
sign of fatigue, regardless of whether the function has issued a warning or not.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain
general limitations.

The Distance Alert function can help the driver become aware if the time interval

display* in order to display Distance Alert...

The tread wear indicator shows the status of the tire's tread.
The tread wear indicator is a narrow elevated strip running across the tire's
longitudinal tread grooves. The letters TWI (Tread Wear Indicator) are visible on
the side of the tire. When approximately 1.6 mm (1/16 inch) is left on the tread,
the tread will be at the same height as the tread wear indicator. Replace the tire
as soon..
