On-Board Diagnostics
Fig . 24 Locat ion of Data Link Connector (D LC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
signed a code . In case of a malfunction, the com­
ponent w ill be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system .
If the light illuminates after a refuel ing, stop the
veh icle and make sure the fue l filler cap is prop­
erly closed (on ly vehicles with gasol ine engine)
¢page 298.
In order to make an accurate d iagnosis, the stor­

Central Locking
Description
You can lock and unlock the veh icle centrally . You
have the following choices:
- Remote control key¢
page 40,
-Sensors in the door handles * ¢ page 40
- Lock cylinder on the driver's door¢ page 42,
or
- Interior central locking switch ¢
page 41.
Turn signals
The turn s ignals flash twice when you unlock the
veh icle and flash once when you lock the veh icle.
If they do not flash, then one of the doors, the
rear lid or the hood is not closed.
Automatic locking (Auto Lock)
The Auto Lock funct ion locks all doors and the
luggage compartment lid once the speed has ex­
ceeded approximately 9 mph (15 km/h).
The vehicle can be unlocked if the opening func­
tion in the central locking system sw itch is used
or one of the door handles is pulled.
In the event of a crash with airbag deployment,
the doors will a lso automat ically unlock to allow
access to the vehicle.
Selective door unlocking
The doors and luggage compartment lid will lock
when they close . You can set in the Infotainment
system whether
only the driver's door or the en­
tire vehicle should be unlocked when unlocking
¢page 41.
Unintentionally locking yourself out
The following conditions prevent you from lock­
ing your remote control key in the vehicle:
- If the driver's door is open, the vehicle cannot
be locked by pressing the~ button on the re­

-On vehicles with a convenience key*, the lug­
gage compartment lid unlocks again after clos­
ing if the most recently used key is in the lug­
gage compartment. The emergency flashers blink four times.
