Interior Switches
Ignition Switch
The ignition key operates the four-position ignition switch. The ignition key can only be inserted or removed
in position 0.
If the engine fails to start, the ignition key must be returned to position 0 before the starter motor is re-engaged.
Do not operate the starter motor for more than 20s without the engine firing. If the engine fires but does not
fully start, let the starter motor cool for at least 2min between starts.
