Cross Traffic Alert (CTA)* limitations
CTA functionality may be reduced in certain sit-uations.

Limitations
CTA has limitations in certain situations, forexample, the CTA sensors cannot "see" throughother parked vehicles or obstructions.
The following are several examples where CTA's"field of vision" may initially be limited andapproaching vehicles cannot be detected untilthey are too close:
The vehicle is pulled far into a parking space
In angled parking spaces, CTA may be "blind" on oneside
CTA's blind area
CTA's "field of vision"
However, as you back your vehicle out of a park-ing space, CTA's "field of vision" expands.
Examples of other limitations include:
•Dirt, ice or snow obstructing the sensors mayreduce the system's function or make itimpossible to detect other vehicles orobjects.
•CTA is deactivated if a trailer's wiring is con-nected to the vehicle's electrical system.

Maintenance
The CTA sensors are located on the inside of therear fenders/bumper.
Keep the highlighted area clean (on both sides of thevehicle)
For the system to function optimally, the areaover and around the sensors must be kept clean.
Do not attach any objects, tape, decals, etc., onthe surface of the sensors.
CAUTION
Repairs to the BLIS/CTA systems and/orrepainting the rear bumper should only bedone by a trained and qualified Volvo servicetechnician.

Road Sign Information (RSI)*
RSI is a feature that helps the driver see roadsigns showing the posted speed limit.
Examples of readable road signs
If the vehicle passes a sign showing the speedlimit, this will be displayed in the instrument paneland the head-up display*.

NOTE
If the vehicle is equipped with the SensusNavigation system, speed-related informationis provided by this system in the followinginstances:
•In cases where the speed limit is givenindirectly (e.g., when driving on highwaysor other major roads).
•If a previously read speed limit sign is nolonger considered valid and no new signhas been passed.
If a third-party navigation system is beingused, RSI has no support for speed-relatedinformation.

WARNING
RSI does not function in all situations and isonly intended to provide supplementary infor-mation.
The driver is always responsible for operatingthe vehicle safely.

Road Sign Information (RSI)*limitations
The RSI function may be limited in certain situa-tions.
RSI may have difficulty reading signs that are:
•Faded
•Located in a curve
•Twisted or damaged
•Positioned high above the road
•Obstructed (by bushes, etc.)
•Partially covered by snow, ice, etc.
•If the digital maps used by the SensusNavigation system* are not up-to-date or do
not contain speed information7.

Driver Alert Control (DAC)
DAC is intended to alert the driver if his/her driv-ing becomes erratic due to e.g., distraction orfatigue.
DAC is designed to help detect a slowly chang-ing driving pattern. It is primarily intended to beused on main roads and is not meant for use incity traffic.
The function activates initially when the vehicle'sspeed first exceeds 40 mph (65 km/h) andremains active as long the speed remains aboveapprox. 38 mph (60 km/h)
A camera monitors the traffic lane's side markerlines and compares the direction of the road withthe driver

If the driving pattern becomesnoticeably erratic, the driver willbe alerted by an audible signaland Driver Alert Time for abreak will appear in the instru-ment panel along with a sym-bol.
The warning will be repeated if the driving patterndoes not change.

WARNING
•DAC is not intended to extend the dura-tion of driving. Always plan breaks at reg-ular intervals to help remain alert.
•A warning from DAC should not beignored. A driver may not be aware ofhow fatigued he/she has become.
•In certain cases, fatigue may not affectthe driver
