least Always maintain a distance of at least 11.8 in (30 cm) between the vehicle and the power washer nozzle. Information about the correct distance is available from the equipment manufacturer.
Move the power washer nozzle around when cleaning your vehicle.
Do not aim directly at any of the following:
• tires
• door gaps, roof gaps, joints etc.
• electrical components
• battery
• connectors
• lights
• seals
• trim elements
• ventilation slots
Damaged seals or electrical components can lead to leaks or failures.
