Automatic Engine Start/Stop
Function
The concept The automatic engine start-stop function
helps save fuel. The system switches off the
combustion engine when conditions for elec‐
tric driving, refer to page 73, have been met.
The ignition or drive readiness remains
switched on.
The tachometer registers 0 rpm. If necessary,
the combustion engine starts automatically.
The combustion engine is also stopped during
the trip when coasting or braking. This driving
condition, in which the vehicle is traveling with‐
out power and energy recovery is not active, is
referred to as coasting, refer to page 73.

▷High stress of the automatic climate con‐
trol in the heating or cooling phase.▷The engine compartment lid is unlocked.▷The vehicle is being optimized for the cur‐
rent driving style, for instance during the
breaking-in period or after a service ap‐
pointment.▷The hybrid system is malfunctioning.
Safety mode
An automatically stopped combustion engine
does not start independently when:
▷The driver's door is open and neither the
brake nor accelerator pedal are depressed.▷Unlocked hood.
The indicator lamps come on. The combustion

Requirements Electric driving is possible:▷The high-voltage battery is sufficiently
charged.▷Transmission position D or R is engaged.▷The drive system is at operating tempera‐
ture.▷The accelerator pedal is only slightly de‐
pressed.▷The driver's door is closed.
Possible up to speed of approx. 35 mph, ap‐
prox. 60 km/h.
Possible cruising range
Depending on the charge of the high-voltage
battery, the vehicle can be driven using electric
power constantly for up to 2-2.5 miles/3-4 km.
CoastingThe combustion engine is automatically stop‐
ped and disengaged from the drive train. This
driving condition is referred to as coasting.
Requirements Coasting is possible:
▷The high-voltage battery is sufficiently
charged.▷Transmission position D or R is engaged.▷The drive system is at operating tempera‐
ture.▷The driver's door is closed.▷In COMFORT mode: when rolling at
speeds exceeding 35 mph, approx.
60 km/h or when braking at speeds above
50 mph, approx. 80 km/h.▷In ECO PRO: mode, when coasting, with‐
out operating the brake, at speeds below
100 mph, approx. 160 km/h.Seite 73DrivingControls73
Online Edition for Part no. 01 40 2 909 774 - VI/13
After the coasting, the combustion or electric
motor restarts depending on the operating
state.
Driving with the combustion
engine: DRIVE
The combustion engine provides the primary
drive power to move the vehicle. If necessary,
the high-voltage battery is charged at the
same time.

Accelerating quickly, such as when passing,
requires the maximum available power from
the electric motor. To do this, apply extra force
to the accelerator pedal.
Energy recovery: CHARGEThe hybrid system makes it possible to con‐
vert kinetic energy into electrical power when
braking and coasting. This recovered energy
charges the high voltage battery. If necessary,
this stored electrical energy is output to the
electric motor.
The following conditions must be met to re‐
cover kinetic energy:▷The vehicle is moving.▷Transmission position D, M/S is engaged.▷The high-voltage battery is not fully
charged.
