DS 3: Checking levels / Brake fluid and Engine coolant

Brake fluid

The level of this fluid should be close to the "MAX" mark. If not, check the brake pads for wear.

To know how often the brake fluid should be replaced, refer to the manufacturer's servicing schedule.

Clean the cap before removing it to refill.

Use only DOT4 brake fluid from a sealed container.

Engine coolant

(Petrol or Diesel)

It is normal to top up this fluid between two services.

The check and top-up must only be done with the engine cold.

A level of coolant that is too low risks causing major damage to the engine; the coolant level must be close to the "MAX" mark without ever going above it.

If the level is close to or below the "MIN" mark, it is essential to top it up.

When the engine is hot, the temperature of the coolant is regulated by the fan.

As the cooling system is pressurised, wait at least one hour after switching off the engine before carrying out any work.

In order to avoid the risk of scalding if you need to top up in an emergency, wrap a cloth around the cap and unscrew the cap by two turns to allow the pressure to drop.

Once the pressure has dropped, remove the cap and top up to the required level.

(Electric)

Do not top up the coolant.

If the level is close to or below the "MIN" mark, it is essential to contact a dealer or a qualified workshop.
