A vehicle (1) comprises a chassis (3) and a tilt cab (3) which is mounted to said chassis and is tiltable with respect to the chassis. The vehicle furthermore comprises a tilting system for tilting said tilt cab (2) relative to the chassis between a lowered position and a raised position. The tilting system comprises a reservoir (7) for hydraulic fluid, a pump (6) and at least one double-acting hydraulic tilt cylinder (4) having a push chamber (44) and a pull chamber (43). The cylinder has a movable piston (45) and piston rod (46) asssembly, wherein the piston separates the push chamber and the pull chamber. The cylinder is connected to the chassis and to the cab, such that when hydraulic fluid is supplied to the push chamber (44) the cab moves to the raised position and when hydraulic fluid is supplied to the pull chamber (43) the cab moves to the lowered position. The tilting system furthermore comprises a control valve (8), which in a first position connects the pump (6) to the push chamber (44) of the cylinder and connects the reservoir (7) to the pull chamber (45), and in a second position connects the pump to the pull chamber of the cylinder and the reservoir to the push chamber. The tilt cylinder has a safety release device, which releases pressure from the pull chamber side to the push chamber side of the tilting system, in the event that the cab is in the lowered position and the pressure in the pull chamber exceeds a predetermined threshold pressure.
