IMPORTANT
Engine damage can occur if water enters the air filter. In depths greater than 25 cm, water could enter the transmission. This reduces the lubri-cating ability of the oils and shortens theservice life of these systems. Damage to any component, engine, transmis- sion, turbocharger, differential or its internalcomponents caused by flooding, hydrostaticlocking or oil shortage, is not covered by thewarranty. In the event of the engine stalling in water, do not try restart - tow the car from the water toa workshop - an authorised Volvo workshop isrecommended. Risk of engine breakdown.
