Warning!
When your vehicle is in electric drive mode the
engine produces significantly lower noise
levels. Other motorists or pedestriants,
especially those who are visually or hearing
impaired, may be unable to hear your vehicle
while it is in motion. This is particularly true
when driving at lower speeds and during
parking maneuvers. At all times, it is the
responsibility of the driver to be aware of their
surroundings, especially in these low speed
situtations. Otherwise other road users could
be seriously or fatally injured. G
Warning!
When the READY indicator in the instrument
cluster is on while the combustion engine is
off, the combustion engine has been turned
off automatically. All vehicle systems
continue to be active as long as the ignition is
switched on. When you open the driver’s door
and unbuckle the seat belt with the READY
indicator on, while the automatic
transmission is in position N or P, the
combustion engine starts automatically.
Therefore, always do the following before
leaving the vehicle: R
Engage the parking brake.
R Shift the automatic transmission into park
position P.
R Switch off the ignition. The READY indicator
goes out.
