cluster displayPractical hints Car care Index Flexible service system (FSS)
(service indicator)
The FSS permits a flexible service schedule that is
directly related to the operating conditions of the
vehicle.
The symbol 9 or ½ appears together with a
message in the multifunction display 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 starter switch to
position 2, or while driving when reaching the service
warning threshold.
The symbols and messages indicate the type of service
to be performed:
9Service A
½Service B
One of the following messages will appear in the display
(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 – PERFORM SERVICE”
The next service due date is displayed either in days or
in miles, depending on your driving style.
Once the suggested service term has passed, the symbol
and message appear for approximately 30 seconds and
a signal sounds every time when turning the electronic
key in starter switch to position 2.

lanes on a highway, move combination switch briefly to
the point of resistance only and release. The turn
signals blink three times.
To operate the turn signals continuously, move the
combination switch past the point of resistance (up or
down). The switch is automatically canceled when the
steering wheel is turned to a large enough degree.
Turn signal failure
If one of the turn signals fails, the turn signal indicator
system flashes and sounds at a faster than normal rate.
