Important safety notes

WARNING
Combustion engines emit poisonous exhaust gases such as carbon monoxide. Inhaling these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave the engine running in enclosed spaces without sufficient ventilation.

WARNING
Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide (CO), and inhaling it can cause unconsciousness and possible death.

Do not run the engine in confined areas (such as a garage) which are not properly ventilated.

If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and corrected immediately. If you must drive under these conditions, drive only with at least one window fully open at all times.

Do not depress the accelerator pedal when starting the engine.

Starting procedure

Shift the automatic transmission to position P.

The transmission position display in the multifunction display shows P.

For further information about the automatic transmission, see .

 If you depress the brake when starting the engine, pedal travel is unusually long and there is less pedal resistance.

Make sure that the parking brake is applied.

Turn the SmartKey in the ignition lock to position 3  and release it as soon as the engine is running.

You can also use the touch-start function.

To do this, turn the SmartKey to position 3  and release it immediately.

The engine then starts automatically.
