Starting and stopping the engine (models without push-button start system)
CAUTION
When operating the Subaru Ascent starter motor, never crank the engine continuously
for more than 10 seconds.
If the engine of the Subaru Ascent does not start within 5 to 10 seconds,
stop cranking and wait at least 10 seconds before attempting again. This pause helps
prevent overh ...
