General information
Enclosed areas
Do not let the engine run in enclosed areas; otherwise, breathing of exhaust fumes may lead to loss of consciousness and death. The exhaust gases contain carbon monoxide, an odorless and colorless but highly toxic gas.
Unattended vehicle
Do not leave the car unattended with the engine running; otherwise, it presents a potential source of danger.
Before leaving the car with the engine running, set the parking brake and place the transmission in position P or neutral to prevent the car from moving.
Frequent starting in quick succession
Avoid repeated futile attempts at starting the car and avoid starting the car frequently in quick succession. Otherwise, the fuel is not burned or is inadequately burned, and there is the danger of overheating and damaging the catalytic converter.
Do not wait for the engine to warm up while the vehicle remains stationary. Start driving at moderate engine speeds.
Starting the engine

Press on the brake pedal and press the Start/Stop button. The engine is cranked until it starts.
