502 Practical hints
Bleeding the fuel system (diesel engine only)
Driving the vehicle until the fuel tank is 
empty is not recommended. Otherwise, air 
may be sucked into the fuel system. If this 
happens, the? malfunction indicator 
lamp (USA only) or the ± malfunction 
indicator lamp (Canada only) comes on 
and the engine may not start immediately 
after refueling the vehicle.
After refueling:
Make sure the automatic transmission 
is set toP.
The gear position indicator in the multi-
function display should be on
P.
Do not depress the accelerator.
Turn the SmartKey in the starter switch 
to position 2 for at least 10 seconds 
(
page 40).
Return the SmartKey in the starter 
switch to position 0 (
page 40).
Turn the SmartKey in the starter switch 
to position 3 (
page 41) and hold it 
there for a maximum of 40 seconds or 
until the engine runs surge-free.
If the engine does not start:
Wait for approximately 2 minutes.
Turn the SmartKey in the starter switch 
to position 3 (
page 41) and hold it 
there for a maximum of 40 seconds or 
until the engine runs surge-free.
If the engine still does not start, do not 
make any further attempts to start the 
engine. Contact an authorized 
Mercedes-Benz Light Truck Center or call 
Roadside Assistance (
page 325).iVehicles with KEYLESS-GO*: If necessary, 
remove the KEYLESS-GO start/stop button from 
the starter switch (
page 41).iWhen the? malfunction indicator lamp 
(USA only) or the ± malfunction indicator 
lamp (Canada only) has been illuminated for the 
above condition, it will remain illuminated until 
the engine was cycled on and off four times in a 
row.
