How it's used
While often used in formal warnings or signs, in spoken Cantonese it carries a slightly more serious or cautionary tone than the more common 小心. It is frequently used when advising someone to be alert to a specific, potentially dangerous situation rather than just general caution. You will often hear it paired with 啲 to soften the command, making it sound more like friendly advice than a stern order.
Examples
Be careful of cars when crossing the road.
Watch your step while walking, the ground is very slippery.

Common mistake
Learners often confuse this with 小心, but 小心 is much more versatile and used in almost every daily situation. Using 當心 in casual, low-stakes contexts can sound slightly stiff or overly dramatic.
