directly related to the operating conditions of the
vehicle.
The symbol 9 or ½ appears together with a
message in the multifunction indicator prior to the next
suggested service.
Depending on operating conditions throughout the year,
the next service is calculated and displayed in days or
distance remaining.The message is displayed for approximately 10 seconds
when turning the electronic key in steering lock to
position 2, or while driving when reaching the service
warning threshold.
The symbols and messages indicate the type of service
to be performed:

(e.g. Service A):
“SERVICE A – IN xx DAYS”
“SERVICE A – IN xx MILES” (Canada: KM)
“SERVICE A – EXCEEDED BY xx DAYS”
“SERVICE A – EXCEEDED BY xx MILES” (Canada: KM)
“SERVICE A – DUE NOW”
The next service due date is displayed either in days or
in miles, depending on your driving style.
