Audi Q3: Driving through water

If you must drive through water, follow these instructions:

  • Check the stability of the ground, the current, and the water depth. If the ground is unstable, there is a strong current, or there are waves, the water must only reach up to the lower edge of the body at the most.
  • Deactivate the Start/Stop system'.
  • Drive carefully and no faster than at walking speeds to prevent the front of the vehicle from creating waves, because they could splash above the lower edge of the body. Oncoming vehicles could also create waves.
  • Do not stop the vehicle while in the water.
  • Do not drive in reverse.
  • Do not turn the engine off.


After driving through water, press the brake pedal carefully to dry the brakes so that the full braking effect will be restored.


Vehicle components such as the motor, drive system, suspension, or electrical system can.

be severely damaged by driving through water.


If possible, avoid driving through salt water because it increases the risk of corrosion. Use fresh water to clean any vehicle components that come into contact with salt water.

Regulation begins shortly after you start driving and is possible at speeds up to approximately 19 mph (30 km/h) and on hills that have an approximately 10-60% grade. If these conditions are met, regulation will be activated and the indicator light will turn on.

Ready mode

If one of the requirements for active regulation is not met, the system will be in ready mode. The indicator tight will turn on. Once the requirements are met again, the system will be able to provide active regulation again.

  • Be ready to apply the brakes at all times when using the hill hold assist.
