how to get a 2017 ford escape 4wd 2 litre into maintence mode
1) Ignition switch ON
2) Press and hold gas pedal, and park brake switch in release (down)
3) While still holding gas pedal and park brake switch, turn ignition to OFF and then ON within 5 sec.
You should hear the caliper motors start working and message on the dash indicating service mode is active. You can then release the pedal and park brake switch and turn off the ignition.
To exit service mode, the process is the same except you must pull up on the park brake switch while performing the steps.
