Activating the vehicle’s drive system
Once the electric drive has started, the vehicle’s drive system is ready for operation. When the
vehicle’s drive system has been activated, the electric drive is switched on.
Requirements for activating the vehicle’s drive system
The vehicle’s drive system can be activated when the following conditions are fulfilled:
—The high-voltage battery is sufficiently charged.
—There is no charging cable connected.
—The temperature of the high-voltage battery is within the operating range.
—Vehicles with starter button: There is a valid vehicle key in the vehicle.
Activating the vehicle’s drive system
—Vehicles with ignition lock: Switch on the ignition (→ Ignition lock, Function).
—Vehicles with starter button: Press the starter button once. The ignition is switched on.

Noises prior to driving
A “clicking” noise may be heard when activating the vehicle’s drive system. This is quite normal,
and no cause for concern.
Recognising vehicle's drive system
The electric drive produces no noticeable motor noises either while the drive system is being
activated or while it is running. It is therefore not possible to recognise that the vehicle's drive
system is ready based on motor noises. Instead, the following features indicate that the vehicle is
ready to drive:
—The needle in the power display in the instrument cluster is positioned at (→ Instrument
cluster, Description).
—The illumination of the needles in the instrument cluster is switched on regardless of whether
the vehicle's exterior lighting is switched on.
—The
indicator lamp lights up in the instrument cluster.
