as possible.
Before starting the engine check the
following:
• Make sure all occupants fasten their
seatbelts.

your vehicle. A significant decrease in
steering assistance could also occur. The
steering does not lock, but higher effort
could be required to steer your vehicle.
When you switch the ignition off, some
electrical circuits, for example airbags,
also turn off. If you unintentionally switch
the ignition off, shift into neutral (N) and
restart the engine.
1. Switch the ignition off to stop the
engine.
2. Put the transmission into neutral (N)
and use the brakes to bring your vehicle
