Running Out Of Fuel (Diesel); Fuel Filter Replacement; (Diesel) - Cadillac XT4 Owner's Manual

To prime the fuel lines:
1. With the engine turned off, press
and hold ENGINE START/STOP
without applying the brake for
five seconds to place the vehicle in
Service Mode. See Ignition Positions
0 205. Wait approximately
five seconds and press ENGINE
START/STOP again to turn it off.
Perform this step three times or
more while the engine is turned off.
2. Press and hold ENGINE START/
STOP while applying the brake for
a maximum of 40 seconds at a
time, with five seconds between
attempts, until the engine starts.
If the engine tries to run, but does
not run smoothly, increase the
engine revolutions slightly by using
the accelerator pedal. This will help
force air through the system.
3. Repeat Step 2 if the engine stalls
and will not restart.
4. After a few attempts, if the engine
still does not start, see your
retailer.
