4.3. Automatic Water Absorption

For continuous water spraying in water, the car features automatic water absorption.

  1. When the car is in water, locate the water intake cover on the bottom of the vehicle.
  2. Unclip or open this cover. The car will then automatically absorb water to refill its internal tank for spraying.
  3. Ensure the cover is securely closed when operating on land or when not using the automatic absorption feature.
