If you are going to be a lot later than 5 minutes, then you should call your manager and tell them about it.
"Hi Barbara, I'm going to be 30 minutes late today. My car is having trouble this morning, so I arranged for a ride with a friend."
"Hey Jack, I'm running a little late today. I just got out of my dentist appointment and it was longer than I expected."
"Mark? This is Pat. I'm stuck in traffic. I think there is an accident that is holding up traffic. I'm going to be a little late."
When you plan on being late ahead of time, it is much easier. For example, if you have a doctor's appointment in the morning, you can tell them in advance and then you don't have to worry about coming in on time.
"I have a doctor's appointment tomorrow morning. Remember I told you earlier this week? I'll come in right after my appointment."
"My daughter has been sick, so I'm going to take her to see the doctor tomorrow morning. Is it ok if I'm a little late? My appointment is at seven in the morning, so I'll only be an hour late."
"I have to take my parents to the airport tomorrow. I shouldn't be too late, but wanted to tell you ahead of time."
