II switches off.
T he glow plug indica to r ligh t will only illumi­
nate fo r approximate ly 1 second w hen t he en ­
gine is warm or the outside temperature is
higher than
46 °F (8 °(). That means yo u can
start the eng ine
immedia tely .
To start the diesel eng ine after the fuel
tank has been run dry
If the fuel tank was r un comp lete ly dry, the
starting process after refue ling with diesel
fuel can take longer than usua l - up to one mi­
nute . This is because the fue l system first has
to be vented of a ir wh ile s tarting .
