t
he vehicle is started and begins to move.
The systems may be heard or felt while they
are operating or while performing diagnostic

It is recommended to leave both systems on
for normal driving conditions, but it may be

1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.

the vehicle may need more time to diagnose
the problem. If the condition persists, see your
dealer.
