Volvo XC90: Driver support / Rear Collision Warning limitations
(Option/accessory.)
(Warning of collision from the rear.)
In some situations, it may be difficult for Rear Collision Warning (RCW) to
warn the driver of a collision risk.
This may be the case if:
- the vehicle approaching from the rear is detected at a late stage
- the vehicle approaching from the rear changes lanes at a late stage
- a trailer, bicycle holder or similar is connected to the vehicle's electrical
system - the function will then be automatically deactivated.
NOTE
In certain markets RCW does not warn with the direction indicators
due to local traffic regulations – in such cases, that part of the function is deactivated.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain
general limitations.
(Option/accessory.)
(Warning of collision from the rear.)
The Rear Collision Warning1 (RCW) function can help the driver
avoid rear-end collisions from vehicles approaching from behind...
(Option/accessory.)
The BLIS1 function is designed to help provide assistance in heavy
traffic with several lanes moving in the same direction by helping the driver to
detect the presence of vehicles in the "blind spot" area behind and to the side
of the vehicle...
Other information:
(* Option/accessory.)
(Warning for crossing traffic when the vehicle is backing up.)
The driver can choose to deactivate the Cross Traffic Alert (CTA) function.

Vehicles with the Start/Stop function are equipped with two batteries – a
more powerful 12 V start battery and a support battery that provides stronger current
during the function's start sequence.
The 12 V support battery is located in a box next to the spring
strut in the engine compartment...
