Starting procedure with the SmartKey
To start the engine using the SmartKey
instead of KEYLESS-GO, pull the Start/Stop button out of the ignition lock.
To start a gasoline engine: turn the
SmartKey to position 3 in the ignition lock
and release it as soon as the
engine is running.
To start a diesel engine: turn the
SmartKey to position 2 in the ignition lock.
The 
preglow indicator lamp in the
instrument cluster lights up.
When the preglow indicator lamp
goes out, turn the SmartKey to position 3
and release it as soon as the
engine is running.
You can start the engine without preglow
if the engine is warm.
