ignition lock and the SmartKey must be in the

only the case if you are not depressing the
brake pedal.

Start/Stop button, the engine starts immedi-
ately.
The Start/Stop button can be removed from
the ignition lock. Then, you can insert the
SmartKey into the ignition lock.

button from the ignition lock when you

Key is in the vehicle.
