Volvo XC90: Specifications / Towing capacity and tongue weight
Towing capacity and tongue weight are shown in the table.

CAUTION
The maximum trailer weights listed are only applicable for altitudes up
to 3280 ft (1,000 m) above sea level. With increasing altitude the engine power
and therefore the car's climbing ability are impaired because of the reduced air
density, so the maximum trailer weight has to be reduced accordingly. The weight
of the car and trailer must be reduced by 10% for every further 3280 ft (1,000 m)
(or part thereof).
The following table lists important weight data for your vehicle.

When loading the vehicle, the maximum gross vehicle weight and permissible
axle weights may not be exceeded...
