Starting the engine
Do not run the engine in enclosed areas; 
otherwise, the inhalation of toxic exhaust 
gases can cause loss of consciousness and 
death. The exhaust gases contain carbon mon-
oxide, an odorless and colorless, but highly 
toxic gas. Never leave an unattended vehicle 
with the engine running; otherwise, such a vehi-
cle represents a potential safety hazard. 
Before leaving the vehicle with the engine run-
ning, always shift into neutral or selector lever / 
transmission position P and apply the parking 
brake forcefully to prevent the vehicle from roll-
ing.<
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in 
which the engine does not start. Otherwise, the 
fuel is not burned or incompletely burned and 
there is a danger of overheating and damaging 
the catalytic converter.<
Do not wait for the engine to warm up while the 
vehicle remains stationary. Start driving right 
away, but at moderate engine speeds.
