Volvo XC90: Starting and driving / Checking trailer lights
When connecting a trailer, make sure that all of the lights on the trailer
are functioning before starting to drive.
Trailer turn signals and brake lights
If one or more of the turn signals or brake lights on the trailer is not working,
a symbol and message will be displayed in the instrument panel. The other lights
on the trailer must be checked manually by the driver before the vehicle is driven.

If any of the trailer's turn signal lights is not working, the turn signal symbol
in the instrument panel will also flash more quickly than normal.
Trailer rear fog light
When a trailer is connected, the vehicle's rear fog light may not illuminate
and rear fog light functionality is instead transferred to the trailer. If this
is the case, check to see if the trailer is equipped with a rear fog light before
activating the vehicle's fog lights when driving with a trailer to help ensure safe
operation.
