Write multiple if statements:

If carYear is before 1967, put "Probably has few safety features.\n" to output.

If after 1970, put "Probably has head rests.\n" to output.

If after 1992, put "Probably has electronic stability control.\n" to output.

If after 2000, put "Probably has tire-pressure monitor.\n" to output.

Ex: If carYear is 1995, then output is:

Probably has head rests.
Probably has electronic stability control.

if carYear < 1967:

print("Probably has few safety features.\n")
if carYear > 1970:
print("Probably has head rests.\n")
if carYear > 1992:
print("Probably has electronic stability control.\n")
if carYear > 2000:
print("Probably has tire-pressure monitor.\n")

Here are the multiple if statements to achieve the desired output:

```python
if carYear < 1967:
print("Probably has few safety features.")
if carYear > 1970:
print("Probably has head rests.")
if carYear > 1992:
print("Probably has electronic stability control.")
if carYear > 2000:
print("Probably has tire-pressure monitor.")
```

This code checks each condition separately and outputs the corresponding message if the condition is satisfied.
