ENGINE MAINTENANCE MODE (FOR PLUG-IN HYBRID)
Starting Engine Maintenance
Mode
To prevent damage of the engine
lubrication system when the engine
has not been started for a long time:
- When the engine is started after 5
weeks of being turned off, the
engine maintenance mode will
operate.
- When the engine maintenance
mode is operated, HEV mode will
be kept on after the engine is ON
and the above message will be dis-
played on the cluster.
If you press the HEV switch to shift
EV mode during engine mainte-
nance mode, the above message will
appear due to priority of the engine
maintenance mode. Stopping Engine Maintenance
Mode
The engine will automatically stop
after sufficient heating. If the engine
is turned OFF without sufficient heat-
ing, the engine maintenance mode
will be operated once more.
