Top-up: Use the green cap on the right to add coolant, filling to the correct level.

Extra caution: If you often need to top up oil, this may mean a leak or engine problem—have it checked by a mechanic.
-
Screenwash Reservoir
-
-
Location: Front left corner of the engine bay, with a blue cap.
-
How to check: Look inside—top up if the level is low.
