tomat ic transmission) or with 1st gear en­
gaged (manual transmission). Otherwise
the vehicle could roll away u nintent ionally .
(D Note
If the eng ine has been under heavy load for
an extended per iod of t ime, heat builds up in
the engine compartment after the engine is
sw itched off and there is a risk of damaging

for at idle for approximately two minutes
be­
fore shutting it off.
