If the housing of the high-voltage battery has been damaged, electrolyte and gases may leak out.
In the event of a vehicle fire, the internal pressure of the high-voltage battery could exceed a critical value. In this case, flammable gas escapes through a bleed valve in the vehicle's underbody.
The gas can ignite.
The hybrid system combines a combustion engine with an electric motor.
the combustion engine is generally switched off.
engine idling only occurs in certain instances.
if the high voltage battery is sufficiently charged the vehicle can start in electric drive without the combustion engine (noiseless start).
if the high voltage battery is not sufficiently charged or the operating temperature of the combustion engine has not been reached, the vehicle can start with the combustion engine.
the combustion engine is switched off as often as possible during the journey.
the vehicle can be accelerated electrically at speeds of up to approximately 120 km/h.
the electric motor supports the combustion engine (boost effect), e.g. when pulling away or accelerating.
the high-voltage battery is discharging.
the electric motor is operated as a alternator when in overrun mode and during braking.
the high-voltage battery is charging.
vehicles with hybrid systems generate significantly less noise than vehicles with combustion engines.
when driving in electric mode the vehicle may not be heard by other road users due to the significantly less noise generated.
depending on the vehicle's equipment and national legislation, the vehicle may be fitted with a sound generator as an acoustic presence indicator (Acoustic Vehicle Indication).
the sound generator generates vehicle noise emissions at a speed of up to 30 km/h.
the simulated vehicle noise emissions adjust automatically to your driving characteristics. the harder you accelerate, the louder the noise is.
this helps other road users, particularly pedestrians and bike riders, to hear your vehicle better.
when driving at speeds above 30 km/h the Acoustic Vehicle Indication switches off. Natural vehicle noise is then sufficient for the vehicle to be heard in good time by other road users.
the sound generator can be switched off via the multimedia system More.
