tion lamp (1) lights up in white. However, this does not indicate abnormality.

In cold weather, DEF level cannot be detected and DEF level caution lamp (1) lights up in white for approxi-
mately 1 hour. However, this does not indicate abnormality.
•
Even if DEF level caution lamp (1) does not light up in white, it may take a long time for DEF level gauge to
display the correct position.
Note that the following cases are not abnormal:
